Description

Technical Field

[0001] This invention relates to the field of health perception technology, and in particular to a method, device and medium for nurses to perceive health based on instantaneous ecological assessment. Background Technology

[0002] With the deepening of research on nursing quality management and occupational health, nurse health perception and management technologies have received widespread attention. Due to the development of wearable technology, mobile interactive terminals, and big data processing, Ecological Instantaneous Assessment (EMA) has been introduced into the field of nursing health to collect nurses' physiological indicators, emotional states, and subjective experiences in real time, enabling dynamic tracking of nurses' health. EMA technology combines subjective questionnaires with objective physiological monitoring, capturing changes in nurses' health status under different nursing tasks, shift stages, and work environments through time-series analysis, thereby improving the real-time nature and precision of health perception.

[0003] Existing technologies still have shortcomings. First, when initiating perceptual questions, the nurse's nursing action status and the safety status of the nursing task are usually not considered. Questions may still be initiated randomly or at fixed times when the nurse is performing a nursing task or in an emergency, thus interfering with the workflow. At the same time, there is a lack of dynamic identification and screening capabilities for nurses in low-interference and stable transition periods. The timing of question initiation is difficult to control precisely and cannot be adapted to specific nursing contexts and shift tasks, resulting in perceptual questions failing to effectively match the nurse's task execution rhythm in actual nursing scenarios. Summary of the Invention

[0004] In view of the aforementioned existing problems, the present invention is proposed.

[0005] Therefore, this invention provides a nurse health perception method based on instantaneous ecological assessment to address the problem that nurses may still randomly or regularly initiate questions while performing nursing tasks or in the midst of an emergency.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: In a first aspect, the present invention provides a nurse's health perception method based on instantaneous ecological assessment, comprising, Nursing shift information and nursing task information are collected to form a nursing context, which is then used as the trigger for ecological instantaneous assessment. The system identifies the occupancy status of nursing actions and the safety status of nursing tasks based on the nursing context. It determines the evaluable time segments based on the time segments where the nursing action occupancy status is unoccupied and the nursing task safety status is safe. It then removes the time segments from the evaluable time segments where the number of times the perceived question is initiated reaches a preset frequency limit. Finally, it filters the remaining evaluable time segments for stable conditions of nursing task switching to obtain stable switching time segments. These stable switching time segments are designated as low-disturbance evaluation windows and used as the timing for initiating perceived questions. The perceived questions include question identifier, question content, question type, display trigger conditions, and feedback collection method. Based on the low-disturbance assessment window, the sensory questions corresponding to the nursing context are matched by the preset question correspondence table and sent to the nurse's interactive terminal. The subjective state of the nurse is received through voice interaction and touch input. At the same time, the physiological state formed by the wrist-worn device worn by the nurse during the sensory question response is obtained. The subjective state and physiological state are mapped to the nursing context to form a sensory record. The perception records are mapped to a risk matrix, and the corresponding health risk areas are identified in the risk matrix. The status labels and level labels corresponding to the health risk areas are retrieved to generate nurses' health status and health status scores. Based on the nurses' health status and health status scores, they are matched with a preset support content library to generate mindfulness audio, micro-rest reminders, and environmental adjustment suggestions, thus forming support content.

[0007] As a preferred embodiment of the nurse health perception method based on instantaneous ecological assessment described in this invention, the nurse shift information includes the start and end times of the shift, the handover time, and the job role. The nursing task information includes nursing task category, nursing task execution time period, nursing task recipient, and nursing task priority; The formation of the nursing context specifically refers to: Nursing task information is chronologically collected according to the start and end times of shifts and the handover time to obtain the shift task sequence. Nursing tasks in the shift task sequence are context-labeled according to job roles and nursing task categories to obtain nursing task labeling results; By associating the results of nursing task marking, the time period of nursing task execution, the object of nursing task, and the priority of nursing task, a nursing context is formed.

[0008] As a preferred embodiment of the nurse health perception method based on instantaneous ecological assessment described in this invention, the step of identifying the occupancy status of nursing actions and the safety status of nursing tasks according to the nursing context specifically includes: Read the nursing task marker results, nursing task execution time period and nursing task priority in the nursing context, and obtain the nursing record status and nursing confirmation status generated by the nurse's interactive terminal; The nursing task marking results, nursing record status, and nursing confirmation status are matched with the preset nursing action status table to obtain nursing action matching results, and the nursing action occupancy status is identified based on the nursing action matching results. The nursing task execution time and priority are matched with a preset nursing safety status table to obtain nursing safety matching results, and the nursing task safety status is identified based on the nursing safety matching results. Link the occupancy status of nursing actions and the safety status of nursing tasks to the nursing context.

[0009] As a preferred embodiment of the nurse health perception method based on ecological instantaneous assessment described in this invention, wherein determining the switching stable time segment as the low-disturbance assessment window specifically involves: Read the occupancy status of nursing actions and the safety status of nursing tasks, and use the occupancy status of nursing actions and the safety status of nursing tasks as the identification results; The recognition results are matched with the preset evaluation window rule table to obtain the evaluation window matching results; The time segments in the evaluation window matching results that represent nursing actions being occupied are masked, and the time segments in the evaluation window matching results that represent nursing actions being unoccupied and nursing tasks being safe are marked as evaluable, thus obtaining evaluable time segments; Read the perception question initiation record before the evaluable time segment, compare the number of initiations in the perception question initiation record with the preset frequency limit, mark the time segment that reaches the preset frequency limit as burdened, and remove the time segment with the burden mark from the evaluable time segment to obtain the low burden time segment. A nursing task switching boundary recognition algorithm is used to filter low-burden time segments. The nursing action occupancy status and nursing task safety status before and after the low-burden time segment are read in chronological order. The time position when the nursing action occupancy status changes from occupied to unoccupied and the nursing task safety status changes from unsafe to safe is marked as a task switching candidate boundary. Within a preset stable time period after the task switching candidate boundary, it is continuously verified whether the nursing action occupancy status remains unoccupied and whether the nursing task safety status remains safe. The low-burden time segment corresponding to the verified task switching candidate boundary is marked as a switching stable time segment. The switching stable time segments are time-series corrected according to the nursing task execution time periods in the nursing context, and switching stable time segments that conflict with subsequent nursing tasks are eliminated to generate a low-disturbance assessment window.

[0010] As a preferred embodiment of the nurse health perception method based on ecological instantaneous assessment described in this invention, wherein: the step of activating perception questions corresponding to the nursing context obtained by matching a preset question correspondence table according to a low-disturbance assessment window specifically includes: Read the nursing context associated with the low-perturbation assessment window, and extract the nursing task labeling results, nursing task execution time period, and nursing task priority from the nursing context; The nursing task marking results, nursing task execution time period, and nursing task priority are matched with the preset question correspondence table to obtain the question matching results; Based on the question matching results, select the perceptual questions that correspond to the nursing context, and determine the initiation time point and effective response time period of the perceptual questions according to the start and end time periods of the low-disturbance assessment window, and generate the perceptual question initiation instruction.

[0011] As a preferred embodiment of the nurse health perception method based on instantaneous ecological assessment described in this invention, wherein: the formation of perception records specifically includes: The nurse's interactive terminal displays the perceived question in the low-disturbance assessment window based on the instruction initiated by the perceived question, and receives the voice interaction content and touch input content input by the nurse in response to the perceived question. The voice interaction content is transcribed into text, and the touch input content is categorized into options. The transcribed text and option categorization results are marked with status to form a subjective state. During the period from the presentation of the sensory questions to the nurse's feedback, physiological data collected by the wristband is acquired and time-stamped to form a physiological state. By associating subjective state, physiological state, perceptual questions, and nursing context, a perceptual record is formed.

[0012] As a preferred embodiment of the nurse health perception method based on instantaneous ecological assessment described in this invention, the generation of nurse health status and health status score specifically includes: Semantic aggregation is performed on the subjective state, physiological state and nursing context in the perception records to form nurse instantaneous state items, nurse physiological response items and nursing scenario items; The nurse's instantaneous state item is mapped to the subjective state dimension in the risk matrix, the nurse's physiological reaction item is mapped to the physiological state dimension in the risk matrix, the nursing context type and the degree of restriction on the initiation of the perceived question in the nursing scenario item are mapped to the nursing task dimension in the risk matrix, and the shift time location in the nursing scenario item is mapped to the shift time period dimension in the risk matrix to form a risk mapping result. Based on the risk mapping results, the region affiliation is compared in the risk matrix pre-divided according to the dimensions of subjective state, physiological state, nursing task, and shift time to determine the health risk area corresponding to the perception record, and the health status label and risk level label corresponding to the health risk area are retrieved. Write the health status label into the nurse's health status, and write the risk level label into the health status score.

[0013] As a preferred embodiment of the nurse health perception method based on instantaneous ecological assessment described in this invention, the formation of supporting content specifically includes: Nurses' health status is categorized into different categories, and their health status scores are assigned to different grade ranges to form supporting index conditions. Based on the supporting index conditions, mindfulness audio, micro-rest reminders, and environmental adjustment suggestions are selected from the preset supporting content library to form candidate supporting content; The candidate support content is arranged in the order of display according to the execution time and priority of nursing tasks in the nursing context, forming the support content to be pushed out; Send the support content to be pushed to the nurse's interactive terminal to form support content that corresponds to the nurse's health status, health status score and nursing context; The support content includes mindfulness audio, micro-rest reminders, and environmental adjustment suggestions. The mindfulness audio includes guided mindfulness instructions and breathing rhythm prompts. The micro-rest reminders include rest movement guidance and rest duration prompts. The environmental adjustment suggestions include suggestions for adjusting at least one of light, noise, and temperature.

[0014] In a second aspect, the present invention provides a computer device including a memory and a processor, wherein the memory stores a computer program, wherein: when the computer program is executed by the processor, it implements any step of the nurse health perception method based on ecological instantaneous assessment as described in the first aspect of the present invention.

[0015] Thirdly, the present invention provides a computer-readable storage medium having a computer program stored thereon, wherein: when the computer program is executed by a processor, it implements any step of the nurse health perception method based on ecological instantaneous assessment as described in the first aspect of the present invention.

[0016] The beneficial effects of this invention are as follows: It uses the nursing context as the trigger for instantaneous ecological assessment, and determines a low-disturbance assessment window based on the occupancy status of nursing actions, the safety status of nursing tasks, burden markers, and the identification results of nursing task switching boundaries. This eliminates the reliance on random or fixed-time initiation of perception questions. Consequently, perception questions can avoid time periods when nurses are performing nursing tasks, handling emergencies, or frequently receiving questions, reducing interference with the continuity of nursing operations, minimizing nurses' resistance to responses due to frequent interruptions, and improving nurses' willingness to respond and the completeness of feedback in real nursing scenarios. Simultaneously, the low-disturbance assessment window aligns with the rhythm of nursing task execution and shift scheduling, enabling perception records to more accurately reflect the nurse's subjective and physiological state in specific nursing contexts. This improves the reliability of nurses' health status and health status scores, providing more suitable support for subsequent mindfulness audio, micro-rest reminders, and environmental adjustment suggestions.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0025] Reference Figures 1-4 As one embodiment of the present invention, this embodiment provides a nurse's health perception method based on instantaneous ecological assessment, comprising the following steps: S1: Collect nurse shift information and nursing task information to form a nursing context, and use the nursing context as the trigger for ecological instantaneous assessment.

[0026] S1.1: Retrieves the shift type, shift start and end time, shift handover time, and job role from the nursing shift schedule record. The shift type indicates the nurse's work status in day shift, night shift, rotating shift, and continuous shift. The shift start and end time limits the time range of the nurse's health perception. The shift handover time marks the transition period between the nurse's entry into and exit from the work status. The job role marks the nurse's responsibilities as the responsible nurse, circulating nurse, treating nurse, and handover nurse in the current shift. The shift type, shift start and end time, shift handover time, and job role are saved as nurse shift information.

[0027] The nursing task category, execution time, patient, and priority are retrieved from the nursing task record. The nursing task category is marked as medication administration, rounds, nursing records, patient communication, emergency response assistance and handover records, doctor's orders verification, patient transfer assistance, treatment assistance, and incomplete nursing task organization. The nursing task execution time is marked as the time when the nursing task occurs within the shift. The nursing task patient is marked as the de-identified task-related object corresponding to the nursing task. The de-identified task-related object includes bed code, nursing area, handover object, circulating area, treatment preparation items, emergency response items, patient transfer assistance items, and incomplete nursing task organization items, but does not include patient name, ID number, contact information, and medical record number. The nursing task priority is marked as the degree of restriction on the timing of the initiation of the perception question by the nursing task. The nursing task category, execution time, patient, and priority are used as nursing task information.

[0028] S1.2: Using the start and end times of the shift as the boundary for collecting nursing task information, nursing task information whose execution time falls within the start and end times of the shift is included in the current shift's scope, and the shift handover time is used as the starting and ending transition nodes of the shift's task sequence; the period from the start time of the shift to the end time of the starting handover time is defined as the first segment of the shift, the period from the end time of the starting handover time to the start time of the ending handover time is defined as the middle segment of the shift, and the period from the start time of the ending handover time to the end time of the shift is defined as the last segment of the shift; nursing task information included in the current shift's scope... Nursing tasks are arranged chronologically according to their execution time. Handover records, bedside rounds, and doctor's orders that occur at the beginning of the shift are placed at the beginning of the shift's task sequence. Medication administration, rounds, nursing records, patient communication, and emergency coordination that occur in the middle of the shift are placed in the middle of the shift's task sequence according to their actual occurrence time. Nursing records, handover records, and the compilation of unfinished nursing tasks that occur at the end of the shift are placed at the end of the shift's task sequence. This ensures that the categories of nursing tasks, the execution time of nursing tasks, the patients receiving nursing tasks, and the priority of nursing tasks form a continuous shift task sequence in the same time order.

[0029] S1.3: Read nursing tasks sequentially from the shift task sequence and match job roles with nursing task categories; when the job role is the responsible nurse and the nursing task category is medication administration, rounds, patient communication, and nursing record keeping, mark the corresponding nursing task as the responsible nursing context; when the job role is the circulating nurse and the nursing task category is rounds, emergency assistance, and patient transfer assistance, mark the corresponding nursing task as the circulating nursing context; when the job role is the treatment nurse and the nursing task category is medication administration, doctor's order verification, and treatment assistance, mark the corresponding nursing task as the treatment nursing context; when the job role is the handover nurse and the nursing task category is handover record keeping, nursing record keeping, and unfinished nursing task organization, mark the corresponding nursing task as the handover nursing context; after completing the context marking, the nursing task retains the nursing task execution time, nursing task recipient, and nursing task priority, forming the nursing task marking result.

[0030] S1.4: The nursing task marking result is used as the context category of the nursing task, the nursing task execution period is used as the time location of the nursing task, the nursing task object is used as the patient bed and nursing matter corresponding to the nursing task, and the nursing task priority is used as the degree of restriction for initiating the perceived question. The nursing task marking result, nursing task execution period, nursing task object, and nursing task priority are bound together according to the same nursing task to form a nursing context that includes context category, time location, patient bed, nursing matter, and degree of restriction for initiation. When the nurse enters the nursing task execution period at the current time, and the nursing task object is consistent with the patient bed and nursing matter currently displayed on the nurse's interactive terminal, the nursing task execution period is used as the candidate trigger time range, the patient bed and nursing matter corresponding to the nursing task object are used as the candidate trigger task range, and the nursing context is written into the ecological instantaneous assessment candidate trigger range composed of the candidate trigger time range and the candidate trigger task range. The nursing task priority in the nursing context is used to restrict whether the perceived question is allowed to be initiated, so that the ecological instantaneous assessment revolves around the real nursing task.

[0031] S2: Identify the occupancy status of nursing actions and the safety status of nursing tasks based on the nursing context. Determine the evaluable time segments based on the time segments where the nursing action occupancy status is unoccupied and the nursing task safety status is safe. Remove the time segments from the evaluable time segments where the number of times the perceived question is initiated reaches the preset frequency limit. Then, filter the remaining evaluable time segments for stable conditions of nursing task switching to obtain stable switching time segments. Determine the stable switching time segments as low-disturbance evaluation windows. Use the low-disturbance evaluation windows as the timing for initiating perceived questions. Perceived questions include question identifier, question content, question type, display trigger conditions, and feedback collection method.

[0032] S2.1: Read the nursing task marker results, nursing task execution time period, and nursing task priority in the nursing context, and obtain the nursing record status and nursing confirmation status generated by the nurse's interactive terminal, specifically: The nursing task marker results, execution time period, and priority are retrieved from the nursing context. The nursing task marker results indicate the type of nursing context to which the nurse's current nursing task belongs, the execution time period indicates the time position of the nurse's current nursing task in the shift task sequence, and the priority indicates the degree of restriction on the initiation of the perceived question. The nursing record status and nursing confirmation status are retrieved from the nurse's interactive terminal. The nursing record status indicates whether the nursing record is in the process of being processed, and the nursing confirmation status indicates whether the nursing confirmation is in the process of being processed. The nursing record status and nursing confirmation status serve as the source of status for identifying the occupancy status of nursing actions and the safety status of nursing tasks.

[0033] S2.2: Match the nursing task marking results, nursing record status, and nursing confirmation status with the preset nursing action status table to obtain the nursing action matching results, and identify the nursing action occupancy status based on the nursing action matching results, specifically: The nursing task marking results, nursing record status, and nursing confirmation status are input into a preset nursing action status table. The preset nursing action status table sets up a correspondence according to the nursing context type, nursing record processing status, and nursing confirmation processing status. When the nursing record status is "recording," the preset nursing action status table marks the nursing action matching result as "record occupied." When the nursing confirmation status is "confirming," the preset nursing action status table marks the nursing action matching result as "confirmed occupied." When the nursing record status is "completed" and the nursing confirmation status is "confirmed," the preset nursing action status table marks the nursing action matching result as "idle transition." The nursing action occupation status is identified as "occupied" based on record occupation and confirmation occupation, and as "unoccupied" based on idle transition.

[0034] To further explain, the nursing action status table consists of nursing context type, nursing record processing status, nursing confirmation processing status, and nursing action matching result. The nursing context type is derived from the nursing task tagging result. The nursing record processing status is set according to not started recording, recording in progress, and completed recording. The nursing confirmation processing status is set according to unconfirmed, confirming, and confirmed. The nursing action matching result is set according to record occupied, confirmation occupied, and idle transition. The nursing action status table is configured by nursing management rules and nurse interaction terminal operation rules before use. For example, when the nursing record processing status is recorded in progress, it corresponds to record occupied; when the nursing confirmation processing status is confirmed in progress, it corresponds to confirmation occupied; and when the nursing record processing status is completed and the nursing confirmation processing status is confirmed, it corresponds to idle transition.

[0035] S2.3: Match the nursing task execution time period and nursing task priority with the preset nursing safety status table to obtain the nursing safety matching result, and identify the nursing task safety status based on the nursing safety matching result, specifically as follows: The nursing task execution time and priority are input into a preset nursing safety status table. The nursing safety status table sets a correspondence according to the occurrence time and urgency of the nursing task. When the nursing task execution time is within the execution range and the nursing task priority corresponds to an emergency nursing task, the nursing safety matching result is marked as prohibited from assessment. When the nursing task execution time is within the execution range and the nursing task priority corresponds to a routine nursing task, the nursing safety matching result is marked as delayed assessment. The execution range is from the start time to the end time of the nursing task execution time. When the nursing task execution time is within the task interval range and the nursing task priority does not correspond to an emergency nursing task, the nursing safety matching result is marked as allowed assessment. The task interval range is the time period between adjacent nursing task execution times that is not occupied by nursing tasks. The nursing task safety status is identified as unsafe based on prohibited assessment and delayed assessment, and as safe based on allowed assessment.

[0036] To further explain, the nursing safety status table consists of the nursing task execution time period, nursing task priority, and nursing safety matching result. The nursing task execution time period is set according to the current execution range and task interval range. The nursing task priority is set according to emergency nursing tasks, important nursing tasks, and routine nursing tasks. Emergency nursing tasks are nursing tasks that require immediate treatment and are not allowed to involve sensory questions. Important nursing tasks are nursing tasks that need to be completed first within the current nursing task execution time period and are only allowed to initiate sensory questions later. Routine nursing tasks are nursing tasks that are executed according to the shift task sequence and are allowed to initiate sensory questions within the task interval range. The nursing safety matching result is set according to prohibited assessment, delayed assessment, and allowed assessment. The preset nursing safety status table is configured by nursing task management rules and nursing safety management rules before use. For example, emergency nursing tasks correspond to prohibited assessment, important nursing tasks correspond to delayed assessment, and routine nursing tasks correspond to allowed assessment within the task interval range.

[0037] The status of nursing actions and the safety status of nursing tasks are written into the corresponding nursing context, so that the nursing context simultaneously includes the nurse's current nursing task, the status of nursing actions, and the safety status of nursing tasks.

[0038] S2.4: Match the recognition results with the preset evaluation window rule table to obtain the evaluation window matching results, specifically: The occupancy status of nursing actions and the safety status of nursing tasks are used as the recognition results. The recognition results are input into a preset evaluation window rule table. The evaluation window rule table sets a correspondence according to the occupancy status of nursing actions and the safety status of nursing tasks. When the occupancy status of nursing actions is occupied, the evaluation window matching result is marked as unevaluable. When the occupancy status of nursing actions is not occupied and the safety status of nursing tasks is unsafe, the evaluation window matching result is marked as postponed. When the occupancy status of nursing actions is not occupied and the safety status of nursing tasks is safe, the evaluation window matching result is marked as evaluable. This allows the evaluation window matching result to indicate whether the time segment corresponding to the recognition result allows the initiation of a perception question.

[0039] To further explain, the assessment window rule table consists of the nursing action occupancy status, the nursing task safety status, and the assessment window matching result. The nursing action occupancy status is set according to occupied and unoccupied, the nursing task safety status is set according to safe and unsafe, and the assessment window matching result is set according to unassessable, deferred assessment, and assessable. The preset assessment window rule table is configured by the nursing action occupancy rules and the nursing task safety rules before use. For example, occupied corresponds to unassessable, unoccupied and unsafe corresponds to deferred assessment, and unoccupied and safe corresponds to assessable.

[0040] S2.5: Mask the time segments in the evaluation window matching results that indicate the nursing action is occupied, and mark the time segments in the evaluation window matching results that indicate the nursing action is not occupied and the nursing task is safe as evaluable, thus obtaining the evaluable time segments, specifically: For time segments in the evaluation window matching results that represent the occupied status of nursing actions, a masking mark is made on the time series so that these time segments are not used to initiate perception questions. For time segments in the evaluation window matching results that represent the unoccupied status of nursing actions and the safe status of nursing tasks, an evaluable mark is made on the time series so that these time segments can be used as available trigger times for perception questions. The time segments after the masking mark and the evaluable mark are arranged in chronological order to form continuous evaluable time segments for the generation of the next low-disturbance evaluation window.

[0041] S2.6: Read the perception question initiation records before the evaluable time segment, compare the number of initiations in the perception question initiation records with the preset frequency limit, mark the time segments that reach the preset frequency limit as burdened, and remove the time segments with burden marks from the evaluable time segments to obtain low-burden time segments, specifically: Before the evaluable time segment enters the low-disturbance evaluation window, the initiation records of perception questions that have been formed before the evaluable time segment are read, and the number of initiations is counted according to the initiation time corresponding to the perception question initiation record. The number of initiations is compared with the preset frequency limit. When the number of initiations reaches the preset frequency limit, the corresponding time segment is marked as a burdened time segment, and a burden mark is written to the burdened time segment. The burdened time segments with burden marks are excluded from the evaluable time segments, and the time segments that have not reached the preset frequency limit and still have evaluable marks are retained to form low-burden time segments.

[0042] To further explain, the frequency limit is set based on the nurse's ability to safely complete the perception questions without affecting the nursing operation during continuous nursing tasks. It takes into account factors such as shift task density, nursing task execution intensity and perception question completion time. For example, the number of perception questions that can be initiated within one hour is three. Time periods exceeding three times are marked as burden time segments and used to eliminate time segments in the assessable time segments that may cause excessive interference to nurses.

[0043] S2.7: The nursing task switching boundary recognition algorithm takes low-burden time segments as input and constructs a state sequence according to the time order of the low-burden time segments. Each time position in the state sequence corresponds to the nursing action occupancy state and the nursing task safety state. An action occupancy code value and a task safety code value are generated for each time position in the state sequence. The action occupancy code value ranges from 0 to 1; when the nursing action occupancy state is occupied, the action occupancy code value is 1, and when the nursing action occupancy state is not occupied, the action occupancy code value is 0. The task safety code value ranges from 0 to 1; when the nursing task safety state is unsafe, the task safety code value is 0, and when the nursing task safety state is safe, the task safety code value is 1. The action occupancy code value and the task safety code value are combined into a state code pair. A state code pair of (1, 0) indicates an unsafe occupancy state, and a state code pair of (0, 1) indicates a safe unoccupancy state. The nursing task switching boundary recognition algorithm compares the state changes of adjacent time positions point by point along the state sequence and calculates the task release transfer value. The calculation formula is: ; in, Indicates the first The task release transfer value corresponding to each time position ranges from -2 to 2. This indicates the coded values ​​used by actions at a location in the previous period. This indicates the occupancy value of the action at the next time position. This represents the task security code value at the next time position. This indicates the task security code value at the previous time position.

[0044] When the status code pair of the current time position is (1, 0) and the status code pair of the next time position is (0, 1), and the task release transfer value is 2, the next time position is recorded as the task switching candidate boundary. Starting from the task switching candidate boundary, continuous low-burden time segments after the candidate boundary are extracted, and the nursing action occupancy status and nursing task safety status corresponding to the continuous low-burden time segments are continuously verified within a preset stable duration. The continuous stable count value is accumulated according to the time positions where the action occupancy code value is continuously 0 and the task safety code value is continuously 1. When the continuous stable count value reaches the count threshold corresponding to the preset stable duration, the continuous low-burden time segment is used as the switching stable time segment. When the action occupancy code value turns to 1 and the task safety code value turns to 0 within the preset stable duration, or when the continuous low-burden time segment overlaps with the subsequent nursing task execution period, the continuous low-burden time segment is excluded, and the switching stable time segment is finally obtained.

[0045] To further explain, the stabilization duration is set based on the time required to complete the perceived question, the task transition interval between the nurse exiting the previous nursing action and entering the next nursing action, the time required for the physiological data collected by the wristband to form a stable segment, and the response preparation time for the nurse's interactive terminal to display the perceived question. It can be set to 30 to 60 seconds, with 30 seconds being the preferred setting. The counting threshold is determined based on the stabilization duration and the time sampling interval of the state sequence. The counting threshold is equal to the value obtained by dividing the stabilization duration by the time sampling interval, where the time sampling interval is the time difference between two adjacent time positions in the state sequence. In actual configuration, the minimum available response time required for the nurse to complete one perceived question can be used as the lower limit, and the upper limit can be set to not intrude on the execution time of subsequent nursing tasks. For example, if the stabilization duration is set to 30 seconds and the time sampling interval is 5 seconds, the counting threshold is 6, which means that only when the action occupancy code value is 0 and the task safety code value is 1 for six consecutive time positions starting from the task switching candidate boundary is the continuous low-burden time segment considered as the switching stable time segment.

[0046] S2.8: Perform time-series correction on the switching stable time segments according to the nursing task execution time periods in the nursing context. When at least one of the following conditions is met—that the switching stable time segment overlaps with the subsequent nursing task execution time period, or that the time between the end time of the switching stable time segment and the start time of the subsequent nursing task execution time period is less than a preset safety interval—the switching stable time segment is identified as a switching stable time segment that conflicts with the subsequent nursing task and is removed. A low-disturbance evaluation window is generated, specifically as follows: According to the nursing task execution time period in the nursing context, the start and end times of the switching stable time segment are compared with the nursing task execution time period of the subsequent nursing task. When at least one of the following conditions is met: the end time of the switching stable time segment enters the nursing task execution time period of the subsequent nursing task, there is a time overlap between the switching stable time segment and the nursing task execution time period of the subsequent nursing task, or the time from the end time of the switching stable time segment to the start time of the subsequent nursing task execution time period is less than a preset safety interval, the corresponding switching stable time segment is marked as a task conflict segment, and the task conflict segment is removed from the switching stable time segment. The remaining switching stable time segments are arranged in chronological order to generate a low-disturbance assessment window. When the shift task sequence enters the start time of the low-disturbance assessment window, the low-disturbance assessment window is associated with the current nursing context, and the start time of the low-disturbance assessment window is used as the initiation time of the perception question.

[0047] To further explain, the safety interval is set based on the time required to complete the perceived question, the preparation time required for the nurse to switch from the perceived question feedback state to the subsequent nursing task execution state, and the priority of the subsequent nursing task; the higher the priority of the subsequent nursing task, the longer the preset safety interval, which can be set to thirty seconds to two minutes.

[0048] Preferably, this invention combines the occupancy status of nursing actions, the safety status of nursing tasks with nursing context, assessment window rules, initiation frequency limits, and task switching boundary recognition algorithms to accurately determine the low-disturbance assessment window. This ensures that perceptual questions are initiated only when nursing actions are completed, nursing tasks are safe, and the nurse is in a stable transition state. Compared with existing technologies, this avoids frequent interference with nurses during periods of high nursing workload or urgent tasks, improving the acceptability and accuracy of instantaneous ecological assessment. At the same time, task switching boundary recognition and preset stable duration ensure that the timing of perceptual question initiation is stable and reliable, effectively reducing the subjective burden on nurses, improving the real-time nature and credibility of health perception, and achieving an innovative effect of natural connection between perceptual question initiation and nursing operations.

[0049] S3: Based on the low-disturbance assessment window, start the perception questions that correspond to the nursing context obtained by matching the preset question correspondence table, send the perception questions to the nurse's interactive terminal, receive the subjective state feedback from the nurse through voice interaction and touch input, and at the same time obtain the physiological state formed by the wrist-worn terminal during the perception question response, map the subjective state and physiological state to the nursing context, and form a perception record.

[0050] S3.1: During the start and end time of the low-perturbation assessment window, read the nursing context associated with the low-perturbation assessment window. When the nursing context associated with the low-perturbation assessment window contains multiple nursing tasks, sort the multiple nursing tasks according to the execution time of the nursing tasks, and read the sorted multiple nursing tasks one by one. Read each nursing task in the nursing context one by one in chronological order, extract the nursing task label results to indicate the type of nursing task to which the nursing task belongs: responsible nursing context, circulating nursing context, therapeutic nursing context, and handover nursing context. Extract the nursing task execution time to indicate the time position of the nursing task in the shift task sequence. Extract the nursing task priority to indicate the degree of restriction of each nursing task on the timing of the initiation of the perception question. Organize the extraction results according to the order of the nursing tasks in the shift task sequence for the next step of question matching.

[0051] S3.2: Read the nursing task marking results, nursing task execution time period, and nursing task priority in sequence, and look up the corresponding perception question type in the preset question correspondence table according to the nursing task marking results. Look up the perception question initiation time range in the preset question correspondence table according to the nursing task execution time period. Look up the perception question initiation restriction in the preset question correspondence table according to the nursing task priority. When the perception question type corresponds to the nursing task marking results and the perception question initiation time range covers the nursing task execution time period, and the perception question initiation restriction allows initiation within the current low-disturbance assessment window, save the corresponding perception question as a question matching result. The question matching result is used to indicate the perception questions that are allowed to be initiated within the current low-disturbance assessment window, providing a basis for subsequent perception question selection and initiation instruction generation.

[0052] To further explain, the question-and-answer table consists of nursing task marking results, nursing task execution time periods, nursing task priorities, perceived question types, perceived question initiation time ranges, and perceived question initiation restrictions. Nursing task marking results are set according to the context of responsible nursing, circulating nursing, therapeutic nursing, and handover nursing. Perceived question types are set according to subjective fatigue, emotional exhaustion, attentional state, and recovery needs. The perceived question initiation time range is set according to the start and end time periods of the low-disturbance assessment window. Perceived question initiation restrictions are set according to nursing task priorities. For example, the responsible nursing context corresponds to subjective fatigue and attentional state, the circulating nursing context corresponds to subjective fatigue and recovery needs, the therapeutic nursing context corresponds to attentional state, the handover nursing context corresponds to emotional exhaustion and recovery needs, emergency nursing tasks correspond to prohibition of initiation, important nursing tasks correspond to delayed initiation, and routine nursing tasks correspond to permission of initiation.

[0053] The perception questions include question identifiers, question content, question types, display trigger conditions, and feedback collection methods. Question identifiers are used to distinguish different perception questions, question content is used to present the nurse's subjective state feedback, question types include subjective fatigue, emotional exhaustion, attention state, and recovery needs, display trigger conditions correspond to the start and end time periods of the low-disturbance assessment window, and feedback collection methods include voice interaction and touch input.

[0054] S3.3: Within the low-disturbance assessment window, each initiable perceptual question in the question matching results is read sequentially, and the perceptual question is checked against the nursing task marking results, nursing task execution time period, and nursing task priority in the nursing context. When the perceptual question completely corresponds to the nursing context and the initiation time of the perceptual question falls within the start and end time period of the low-disturbance assessment window, the perceptual question is written into the initiable list. According to the allowed initiation time period and order of each perceptual question in the initiable list, the perceptual question is time-located to determine the initiation time point and effective response time period of the perceptual question, and the corresponding perceptual question initiation instruction is generated. The perceptual question initiation instruction includes the perceptual question identifier, initiation start time, and effective response time period, and is arranged sequentially according to the start and end time periods of the low-disturbance assessment window, for nurses to initiate perceptual questions in sequence on the interactive terminal.

[0055] S3.4: During the start and end time of the low-disturbance assessment window, the initiation instructions for the perception questions are read sequentially, and each perception question is displayed on the nurse's interactive interface in the order of the instructions. When the nurse inputs the perception questions by voice on the interactive interface, the voice content is collected and converted into text using a speech-to-text tool. The text transcription result is then bound to the corresponding perception question. When the nurse inputs the perception questions by touch on the interactive interface, the touch selection is recorded and categorized according to the perception question options. The categorization result is then bound to the corresponding perception question. The text transcription result and the categorization result are marked with status, including the answer completion status, answer type status, and corresponding nursing task marking result, forming a subjective status. The subjective status is associated with the low-disturbance assessment window and the nursing context in the order of the perception questions, ensuring that each subjective status corresponds to a specific nursing task and the allowed initiation time period.

[0056] S3.5: Record the display start time when the perception question begins to be displayed, and record the feedback completion time when the nurse completes the voice interaction and touch input. The period between the display start time and the feedback completion time is defined as the perception question response period. During the perception question response period, read the physiological data collected by the wristband, including heart rate, heart rate variability, skin conductance response, and activity intensity. Read the sampling rates set by the wristband for heart rate, heart rate variability, skin conductance response, and activity intensity, and write the sampling rates into the acquisition attributes of the physiological data. Perform moving average filtering on heart rate and heart rate variability, baseline drift correction on skin conductance response, and short-term smoothing on activity intensity to obtain filtered physiological data. Filter the filtered physiological data. Physiological acquisition points that exceed the wrist-worn measurement range, have missing timestamps, have consecutive repetition values ​​exceeding the preset repetition duration, or exhibit sudden changes in activity intensity are marked as spurious acquisition points. These spurious acquisition points are then removed from the filtered physiological acquisition content to obtain valid physiological acquisition content. The duration of valid physiological acquisition content is calculated according to the perception question response period. When the duration of valid physiological acquisition content reaches the preset valid proportion of the perception question response period, the corresponding perception question response period is marked as a valid segment. Based on the acquisition time of the physiological acquisition content, heart rate, heart rate variability, skin conductance response, and activity intensity in the valid physiological acquisition content are mapped to the perception question response period, and the mapped valid physiological acquisition content is written into the timestamp to form the physiological state corresponding to the perception question response period.

[0057] To further explain, the repetition duration is set based on the normal fluctuation characteristics of the continuously acquired signals from the wrist-worn device, and can be set to 3 to 5 seconds; the effective ratio is set based on the effective coverage of the physiological content acquired during the response period of the perceived question, and can be set to 80% to 90%.

[0058] S3.6: Match the subjective state corresponding to each perception question with the physiological state during the perception question response in chronological order. Correspond the text transcription results, touch option classification results, and status markers of the subjective state with the heart rate, heart rate variability, skin conductance response, and activity intensity of the physiological state. Bind the matched subjective and physiological states with the perception question identifiers and the nursing task markers, nursing task execution time periods, and nursing task priorities in the nursing context associated with the low-disturbance assessment window. Integrate the association information of subjective state, physiological state, perception question, and nursing context to generate a complete perception record for subsequent health status and health status scoring.

[0059] S4: Map the perception records to the risk matrix, determine the health risk areas corresponding to the perception records in the risk matrix, retrieve the status labels and level labels corresponding to the health risk areas, generate the nurse's health status and health status score, and match the nurse's health status and health status score in the preset support content library to generate mindfulness audio, micro-rest reminders and environmental adjustment suggestions to form support content.

[0060] S4.1: Read subjective state, physiological state, and nursing context from the perception record. Convert the text transcription results, touch option classification results, and status markers in the subjective state into numerical scores according to preset scoring rules, and quantify and aggregate them according to subjective fatigue, emotional exhaustion, attention state, and recovery needs to form the nurse's instantaneous state item; aggregate the heart rate, heart rate variability, skin conductance response, and activity intensity in the physiological state according to heart rate response, neural regulation response, stress response, and activity load to form the nurse's physiological response item; aggregate the nursing task marking results, nursing task execution time period, and nursing task priority in the nursing context according to nursing context type, shift time location, and degree of restriction on the initiation of perception questions to form the nursing scenario item; the nurse's instantaneous state item, nurse's physiological response item, and nursing scenario item together serve as the input content for risk matrix positioning.

[0061] To further explain, the scoring rules are configured by nursing health assessment rules and nurse interaction interface question rules, including quantitative standards, scoring ranges, and mapping methods for each subjective state dimension. Specifically, these include: quantitative grading standards for subjective fatigue, emotional exhaustion, attention status, and recovery needs. Each grading standard maps text transcription results, touch option classification results, and status markers to numerical scores, and assigns values ​​according to a scoring range, for example, from 0 to 5. The scoring rules can be adjusted before use based on nurse shift intensity, nursing task complexity, and historical subjective assessment records to ensure that the scoring results reflect the true subjective state and are applicable to subsequent risk matrix positioning.

[0062] S4.2: Map the nurse's instantaneous state items (subjective fatigue, emotional exhaustion, attention state, and recovery needs) to the subjective state dimension in the risk matrix; map the nurse's physiological response items (heart rate response, neural regulation response, stress response, and activity load) to the physiological state dimension in the risk matrix; map the nursing context type and the degree of restriction on the initiation of perceptual questions in the nursing scenario item to the nursing task dimension in the risk matrix; map the shift time location in the nursing scenario item to the shift time period dimension in the risk matrix; locate the corresponding matrix position of the perceptual record in the risk matrix according to the intersection of the subjective state dimension, physiological state dimension, nursing task dimension, and shift time period dimension, and save the matrix position as the risk mapping result for subsequent delineation of health risk areas.

[0063] S4.3: Based on the risk mapping results, read the matrix position corresponding to the perception record in the risk matrix pre-divided according to the dimensions of subjective state, physiological state, nursing task, and shift time. Then, compare the matrix position with the pre-divided health risk areas within the risk matrix. When the matrix position falls into the physical load area, the perception record is assigned to the physical fatigue health risk area; when it falls into the emotional depletion area, it is assigned to the emotional stress health risk area; when it falls into the attention decline area, it is assigned to the attention fluctuation health risk area; and when it falls into the recovery need area, it is assigned to the insufficient recovery health risk area. After completing the assignment of health risk areas, read the health status label and risk level label bound to the health risk area. The health status label is used to represent the nurse's health status, and the risk level label is used to represent the health status score.

[0064] To further explain, health risk areas are pre-divided according to the dimensions of subjective state, physiological state, nursing task, and shift / time period before the risk matrix is ​​used. The subjective state dimension includes subjective fatigue, emotional exhaustion, attention state, and recovery needs. The physiological state dimension includes heart rate response, neural regulation response, stress response, and activity load. The nursing task dimension includes nursing context type and degree of restriction initiation of perceived questions. The shift / time period dimension includes pre-shift, during-shift, end-shift, and shift handover periods. The matrix range corresponding to subjective fatigue and activity load is divided into physical fatigue health risk areas. The matrix range corresponding to emotional exhaustion and stress response is divided into emotional stress health risk areas. The matrix range corresponding to attention state, heart rate response, and nursing task dimensions is divided into attention fluctuation health risk areas. The matrix range corresponding to recovery needs and shift / time period dimensions is divided into inadequate recovery health risk areas. Health status labels and risk level labels are then bound to each health risk area.

[0065] S4.4: After reading the health status labels corresponding to the health risk areas, write the health status labels into the nurse's health status according to the nurse's identity and nursing task sequence associated with the perception records and nursing context, so that the nurse's health status includes health information such as subjective fatigue, emotional exhaustion, attention status, and recovery needs; after reading the risk level labels corresponding to the health risk areas, write the risk level labels into the health status score according to the shift time and nursing task priority associated with the perception records and nursing context, so that the health status score can reflect the nurse's overall health risk level during the current shift task.

[0066] S4.5: Subjective fatigue, emotional exhaustion, attentional state, and recovery needs in the nurse's health status are categorized into physical fatigue, emotional stress, attentional fluctuations, and insufficient recovery, respectively. The health status scores are then assigned to low-risk, medium-risk, and high-risk ranges, forming a support index condition composed of status categories and level ranges. The corresponding content is searched in a preset support content library according to the support index condition. When the support index condition is physical fatigue, micro-rest reminders are selected; when it is emotional stress, mindfulness audio is selected; when it is attentional fluctuations, environmental adjustment suggestions are selected; and when it is insufficient recovery, both micro-rest reminders and mindfulness audio are selected. The prompt intensity and display priority of the candidate content are adjusted according to the low-risk, medium-risk, and high-risk ranges to form candidate support content.

[0067] S4.6: According to the nursing task execution time period in the nursing context, check whether the candidate support content falls within the current nursing task execution time period; when the candidate support content overlaps with the current nursing task execution time period, extend the candidate support content to the dedicated support content trigger window after the current nursing task ends, ensuring that it does not overlap with the perception questions initiated in the low-disturbance assessment window; when the candidate support content does not overlap with the current nursing task execution time period, retain the original display time period of the candidate support content; then arrange the display order of the candidate support content according to the nursing task priority. When the nursing task priority corresponds to an emergency nursing task, move the non-immediate content in the candidate support content to the back; when the nursing task priority corresponds to a routine nursing task, arrange the mindfulness audio, micro-rest reminders, and environmental adjustment suggestions according to the risk correspondence of the candidate support content to form the support content to be pushed.

[0068] S4.7: Send the support content to be pushed to the nurse's interactive terminal in the order of display. The nurse's interactive terminal will display mindfulness audio, micro-rest reminders, and environmental adjustment suggestions during the corresponding display period. When sending the support content to be pushed, bind the support content to be pushed with the nurse's health status, health status score, and nursing context, so that mindfulness audio corresponds to the emotional stress category, micro-rest reminders correspond to the physical fatigue and insufficient recovery categories, and environmental adjustment suggestions correspond to the attention fluctuation category. The support content to be pushed after the binding is completed will be the support content corresponding to the nurse's health status, health status score, and nursing context.

[0069] This embodiment also provides a computer device applicable to the nurse health perception method based on ecological instantaneous assessment, comprising: a memory and a processor; the memory is used to store computer-executable instructions, and the processor is used to execute the computer-executable instructions to implement the nurse health perception method based on ecological instantaneous assessment as proposed in the above embodiment.

[0071] In summary, this invention uses the nursing context as the trigger for instantaneous ecological assessment and determines a low-disturbance assessment window based on the occupancy status of nursing actions, the safety status of nursing tasks, burden markers, and the identification results of nursing task switching boundaries. This eliminates the reliance on random or fixed-time initiation of perception questions. Consequently, perception questions can avoid periods when nurses are performing nursing tasks, handling emergencies, or frequently receiving questions, reducing interference with the continuity of nursing operations, minimizing nurses' resistance to responses due to frequent interruptions, and improving nurses' willingness to respond and the completeness of feedback in real nursing scenarios. Simultaneously, the low-disturbance assessment window aligns with the rhythm of nursing task execution and shift scheduling, enabling perception records to more accurately reflect the nurse's subjective and physiological state in specific nursing contexts, improving the reliability of nurses' health status and health status scores, and providing more suitable support for subsequent mindfulness audio, micro-rest reminders, and environmental adjustment suggestions.
