Description

Technical Field

[0001] This invention relates to the field of medical information management technology, specifically to a closed-loop handover system for the entire surgical process based on a smart terminal. Background Technology

[0002] The complete handover process for surgical patients is a crucial aspect of hospital clinical nursing work. It encompasses the entire process of transferring the patient from the ward to the anesthesia preparation room, operating room, post-anesthesia recovery room, and back to the ward. The handover includes core medical information such as the patient's identity, vital signs, surgical site, and management of tubing. The accuracy and continuity of the surgical handover directly affect surgical safety and patient treatment outcomes, and are essential for reducing the risk of medical accidents.

[0003] In the current handover process, the hospital has replaced the inefficient traditional methods of verbal communication and paper-based records with the introduction of medical personal digital assistant terminals. Furthermore, according to nursing quality management requirements, each handover requires reviewing and verifying all handover items on the handover form. However, existing technology generally uses static handover form templates, which list all verification items, resulting in a large amount of information to observe; moreover, there are redundant handover items unrelated to the current surgery, interfering with nurses' focus and judgment when verifying handover items, making it difficult to quickly locate the required items.

[0004] Therefore, there is an urgent need for a closed-loop handover system for the entire surgical process based on smart terminals to improve the verification efficiency during the handover process and facilitate the refined management of handover projects. Summary of the Invention

[0005] The purpose of this invention is to address the technical problem in existing static handover forms where the items to be checked cannot be dynamically adjusted according to the patient's surgical information, resulting in redundant handover items that interfere with nurses' observation of information and reduce verification efficiency. This invention provides a closed-loop handover system for the entire surgical process based on a smart terminal. This system dynamically constructs individualized surgical handover forms based on the surgical patient's surgical information and preoperative nursing information, reducing redundant information in the handover forms, facilitating rapid verification by nurses, and improving handover efficiency.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution: A closed-loop handover system for the entire surgical process based on a smart terminal includes: The data module is configured to acquire patients' preoperative nursing information and surgical information; The handover module is configured to determine multiple handover pairs and handover paths based on surgical information. The handover item module is configured to form a first set of handover items mapped from surgical information and preoperative nursing information; extract handover items from historical surgical handover forms obtained from surgical information to form a second set; calculate the difference between the second set and the first set to obtain optional items; and add the selected handover items from the optional items to the first set. The handover form module is configured to assign one or more handover pairs to the handover items in the first set; combine the handover items under each handover pair to form a department handover form; and combine multiple department handover forms according to the handover path to obtain the current surgical handover form. The handover management module includes multiple handover pairs. When handover is performed according to the handover path, it receives and verifies the results, updates the department handover form, and synchronizes it to the current surgical handover form.

[0007] Compared with the prior art, the beneficial effects of the present invention include: 1. This invention provides a closed-loop handover system for the entire surgical process based on intelligent terminals. It realizes an in-hospital handover process where surgical patients begin in the ward, sequentially move to the anesthesia preparation room, operating room, and post-anesthesia recovery room, and then return to the ward. By defining the handover path and direction based on surgical information, the surgical handover process can be standardized, reducing information omissions and promoting continuity and completeness. The comprehensive handover content extracted from historical records, combined with a handover form determined based on patient surgical information, ensures detailed patient records while reducing redundant entries, facilitating refined management of handover information and ensuring accurate and smooth handover processes. Furthermore, by configuring mutually exclusive modification permissions for the handover form between the transferring and receiving parties, accountability is ensured, reducing adverse events related to surgical handover and supporting the traceability of handover information.

[0008] 2. This invention provides a closed-loop handover system for the entire surgical process based on a smart terminal. By analyzing the mapping rules between multiple surgical information, preoperative nursing information, and handover items in historical surgical handover forms, a preset mapping table is constructed. Based on the patient's individualized surgical and preoperative nursing information, the system intelligently matches and recommends handover items relevant to that patient from this preset mapping table. This enables the dynamic generation of individualized handover forms for different patients, effectively reducing the interference of redundant handover items unrelated to the current surgery on nursing staff. It also helps solve the information overload problem caused by static templates that list all verification items, allowing nursing staff to quickly focus on the patient's individualized verification items, thus improving the accuracy of verification handover data and increasing handover efficiency.

Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of the present invention can be combined with each other. It should be noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. The terms "first," "second," "historical," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0011] It is important to note that, under current medical conditions and resources, patient surgical information is entered by doctors through their workstations. This process involves binding surgical information, the patient's unique identifier, and the doctor's unique identifier before sending the information to the surgical anesthesia system. The chief resident then schedules the patient's surgery based on the urgency of their condition. Therefore, there is typically a time delay between the generation of patient surgical information and the execution of the surgery. The handover system provided by this invention utilizes this time delay to generate individualized surgical handover forms with associated surgical information for the patient, reducing redundant handover items and improving handover efficiency.

[0012] For example Figure 1 and Figure 2 As shown in the first embodiment of the present invention, a structural schematic diagram of a closed-loop handover system for the entire surgical procedure based on a smart terminal is provided, as well as a flowchart of the first handover process configured in the handover system. The system includes: The data module is configured to acquire patients' preoperative nursing information and surgical information; The handover module is configured to determine multiple handover pairs and handover paths based on surgical information. The handover item module is configured to form a first set of handover items mapped from surgical information and preoperative nursing information; extract handover items from historical surgical handover forms obtained from surgical information to form a second set; calculate the difference between the second set and the first set to obtain optional items; and add the selected handover items from the optional items to the first set. The handover form module is configured to assign one or more handover pairs to the handover items in the first set; combine the handover items under each handover pair to form a department handover form; and combine multiple department handover forms according to the handover path to obtain the current surgical handover form. The handover management module includes multiple handover pairs. When handover is performed according to the handover path, it receives and verifies the results, updates the department handover form, and synchronizes it to the current surgical handover form.

[0013] Specifically, the handover system provided by this invention is interconnected with both the hospital information system and the surgical anesthesia system. Through a data module, it retrieves preoperative nursing information and surgical information from the hospital information system and the surgical anesthesia system based on the patient's unique identifier, such as their hospital number. Alternatively, it sends updated departmental handover data to the surgical anesthesia system for synchronization. Preoperative nursing information includes, but is not limited to: patient identification information (name, gender, age, hospital number, etc.), vital signs (temperature, pulse, respiration, blood pressure, etc.), tubing information (whether an indwelling intravenous catheter is present, whether a urinary catheter is in place, etc.), and skin condition (pressure points, location of existing pressure sores, etc.). Surgical information includes, but is not limited to: surgical name, preoperative diagnosis, surgical procedure, anesthesia method, and surgical site.

[0014] It is important to note that the surgical and nursing information in this invention consists of text data recorded by medical staff regarding medical procedures. This text data needs to be extracted or converted into standardized terminology. Using natural language processing techniques such as keyword matching and syntactic analysis, this text data is broken down into structured clinical text. The clinical text is then compared with a standard terminology database. If a clinical text successfully matches a variant of a standard term in the database, the clinical text is replaced with the corresponding terminology text. The standard terminology database includes multiple sub-databases such as a surgical terminology database and a nursing terminology database. Each sub-database stores the correspondence between clinical text and its variant forms (synonyms, abbreviations, colloquial expressions, etc.) and the terminology text.

[0015] The handover module receives surgical information from the data module. Using natural language processing technologies such as keyword matching and syntactic analysis, it extracts the anesthesia method from the surgical information. Based on whether the anesthesia method is extracted, it determines whether the anesthesia preparation room needs to be included. Then, it plans the various departments in the handover path and the patient's handover direction between these departments. Typically, routine surgeries require general or local anesthesia. In this case, the responsible departments in the handover path include: ward, anesthesia preparation room, operating room, and recovery room. Correspondingly, the handover pairs formed according to the handover direction include: ward-anesthesia preparation room, anesthesia preparation room-operating room, operating room-recovery room, and recovery room-ward. Some day surgery minimally invasive procedures do not require anesthesia. In this case, the responsible departments in the handover path include: ward, operating room, and recovery room. The corresponding handover pairs include: ward-operating room, operating room-recovery room, and recovery room-ward.

[0016] The handover module receives surgical and preoperative nursing information from the data module to identify the key handover items for the current surgery, avoiding the introduction of irrelevant items. This preoperative or postoperative nursing information, typically present in standard surgical or nursing procedures, does not vary from patient to patient. Therefore, once the patient's surgical information is determined, it can be retrieved using a pre-defined mapping table. This table retrieves derived postoperative nursing information based on surgical information such as surgical name, surgical procedure, surgical operation, and anesthesia method; and retrieves continuing preoperative nursing information based on preoperative nursing information such as vital signs, tube management, and skin condition. For this preoperative and postoperative nursing information, the mapped handover items are obtained according to the correspondence between nursing information and handover items in the pre-defined mapping table, forming the first set. The pre-defined mapping table is constructed using multiple mapping rules summarized from medical and nursing experience based on historical surgical information, historical preoperative nursing information, and corresponding historical surgical handover forms.

[0017] It should be noted that the postoperative nursing information in this invention refers to the patient's nursing information while the patient is still in the handover process after surgery.

[0018] It should be noted that the derivation of postoperative nursing information from surgical information in this invention refers to a statistical association analysis based on the co-occurrence patterns of surgical information and surgical nursing information observed in clinical practice, without presupposing a causal relationship between postoperative nursing information and surgical execution.

[0019] The surgical handover form is linked to surgical information, and patients undergoing the same surgery have a higher similarity in handover items. The handover item module retrieves historical surgical handover forms from the surgical anesthesia system based on surgical information such as the surgical name and preoperative diagnosis, directly extracting handover items to form a second set. A difference operation is performed between the second set and the first set to obtain handover items that appeared in historical surgical handover forms but were not mapped to the first set by the current mapping rules; these are recorded as optional items. These optional items may be specific handover items added during surgery due to surgical risks in past patients, and are relevant for handover items requiring attention. For example, if an elderly patient required endotracheal intubation due to acute respiratory distress, the same situation may exist for currently older patients. Within the surgical time delay window, the handover item module can send these optional items to the terminals of each department. Departmental nursing staff can then determine, based on their experience, whether there are any handover items requiring attention, and send the selected handover items to the handover item module and add them to the first set.

[0020] The handover form module receives a first set from the handover item module. It analyzes each handover item in the first set and assigns it to one or more handover pairs based on the applicable responsible department. For example, the "intravenous access" handover item will be assigned to all department handover forms. The applicable responsible department is determined by statistical analysis of handover items in historical surgical handover forms, and this department is set as the identifier for the handover item to establish association. Furthermore, the handover management dimension for each handover item can be obtained by statistical analysis of historical surgical handover forms, including but not limited to patient identity information, vital signs, tubing management, skin condition, and preoperative preparation. These handover management dimensions are preset in the handover form module. Then, the handover form module combines the handover items from each handover pair according to the preset handover management dimensions to form department handover forms, including preoperative handover records, anesthesia preparation room handover records, postoperative handover records, and recovery room handover records. Finally, the handover form module combines multiple departmental handover forms according to the handover path sequence to form the current surgical handover form, and sends the current surgical handover form to the surgical anesthesia system for synchronization and data saving.

[0021] The handover management module includes multiple handover pairs, which form a handover path according to the handover direction. The handover pairs verify patient identity information by scanning patient wristbands (QR codes, barcodes, etc.) or RFID tags associated with the patient's unique identifier. Based on the patient's unique identifier, they retrieve the corresponding department handover form from the hospital information system and display it on the terminal associated with the handover pair. Nursing staff in the responsible department of the handover pair check each handover item on the department handover form displayed on the terminal. The checks include verifying the consistency of the patient's identity information, whether the values ​​of the handover items match the patient's actual condition, and whether the numerical information is within the normal range. If discrepancies are found, one party in the handover pair records the difference, updates the department handover form, and after the nursing staff clicks submit, the department handover form is synchronized to the current surgical handover form, ensuring that the current surgical handover form always reflects the latest handover status.

[0022] This invention provides a closed-loop handover system for the entire surgical process based on a smart terminal. By analyzing historical surgical handover forms and mapping rules between multiple surgical information, preoperative nursing information, and handover items, a preset mapping table is constructed. Based on the patient's individualized surgical and preoperative nursing information, the system intelligently matches and recommends handover items relevant to that patient from this preset mapping table. This enables the dynamic generation of individualized handover forms for different patients, effectively reducing the interference of redundant handover items unrelated to the current surgery on nursing staff. It also helps solve the information overload problem caused by static templates that list all verification items, allowing nursing staff to quickly focus on the patient's individualized verification items, thus improving the accuracy of verification handover data and increasing handover efficiency.

[0023] Furthermore, the handover management module is also configured as follows: Based on the handover direction of the department handover form, the handover pair is divided into the transferring party that provides the department handover form and the receiving party that verifies the department handover form; the operating permissions of the transferring party and the receiving party on the department handover form are configured to be mutually exclusive.

[0024] Specifically, the access permissions for the department handover form can be modification permissions. The handover path always starts from the ward, passes through the anesthesia preparation room, operating room, and recovery room, and finally returns to the ward, forming a closed loop. Therefore, the handover direction of the department handover form remains fixed. To clarify responsibility, the transferring and receiving parties cannot modify the department handover form simultaneously during the handover, and the party with modification permissions must remain consistent across different handover pairs within the same handover path. Preferably, based on the current medical scenario, the transferring party is configured to have modification permissions. By configuring that only one party can have modification permissions at a time, the clear division of responsibilities during the handover process is ensured, data conflicts caused by simultaneous editing by both parties are avoided, and the accuracy and reliability of the handover are improved.

[0025] Meanwhile, the handover management module records key information about the handover process, including handover time, nursing staff identity, verification details, and updated content, generating a complete handover traceability record. These records are used for subsequent quality traceability, risk analysis, and process optimization.

[0026] Furthermore, the transferring or receiving party shall include at least the ward terminal, operating room terminal, and recovery room terminal; the corresponding departmental handover forms shall include at least the preoperative handover form, the postoperative handover form, and the recovery room handover form. The handover process is configured according to the handover path as follows: The ward terminal, operating room terminal, and recovery room terminal are connected sequentially along the handover direction. The ward terminal updates the preoperative handover form, the operating room terminal updates the postoperative handover form, and the recovery room terminal updates the recovery room handover form. Each terminal synchronizes the update results to the current surgical handover form. When adjacent terminals are handed over, the receiving party obtains and displays the updated department handover form from the transferring party based on the patient's unique identifier. If there is a difference between the value of the handover item and the patient's actual value during the handover, the corresponding department handover form is updated based on the new value filled in by the nursing staff and synchronized again to the current surgical handover form.

[0027] Furthermore, an anesthesia preparation room terminal is also included between the ward terminal and the operating room terminal; the corresponding department handover form also includes an anesthesia handover form; The handover process is configured according to the handover path as follows: The handover direction has been adjusted to connect sequentially from the ward terminal, anesthesia preparation room terminal, operating room terminal, recovery room terminal to the return ward terminal; During the anesthesia preparation room, the terminal updates the anesthesia handover form and synchronizes it to the current surgical handover form. Other terminals simultaneously update the corresponding department handover forms to the current surgical handover form.

[0028] Specifically, for example Figure 3 and Figure 4 As shown, this embodiment takes the entire handover process, including the anesthesia preparation room, as an example. The transferring and receiving parties include ward terminals, anesthesia preparation room terminals, operating room terminals, and recovery room terminals. The corresponding departmental handover forms include preoperative handover forms, anesthesia handover forms, postoperative handover forms, and recovery room handover forms. The handover process is configured according to the handover path as follows: sequential connection from ward terminal, anesthesia preparation room terminal, operating room terminal, recovery room terminal to the final return to the ward terminal.

[0029] After receiving the surgical information entered by the doctor, the surgical anesthesia system sends a first notification to the handover system to alert the patient to the new surgical information. Upon receiving the first notification, the handover system requests surgical information based on the patient's unique identifier, generates a handover pair, a handover path, and an initial first set, and sends the initial first set and optional items to the terminals corresponding to each department along the handover path. Nurses in each department verify the initial first set and select the handover items they need to focus on from the optional items. The system then receives the first set and selected handover items submitted by the nurses, adds the selected items to the initial first set, and obtains the first set used to form the current surgical handover form. This formed surgical handover form is then sent to the surgical anesthesia system. After receiving the surgical schedule entered by the doctor, the surgical anesthesia system sends a second notification to the handover system to remind the patient of the surgical time. Upon receiving the second notification, the handover system sets a reminder for the patient's surgical time. When the surgical time arrives, the handover system sends a pre-operative preparation notification to the terminals of each department, and each department begins the handover process according to the handover path.

[0030] Ward nurses use a ward terminal to scan the patient's wristband to obtain the patient's unique identifier. Based on this identifier, they retrieve the preoperative handover form and verify and update all information on it according to the patient's current condition. This includes verifying the patient's identity information, the clarity of the surgical site markings, the stability of vital signs such as heart rate and respiration, the placement of the indwelling catheter, and preoperative medication administration. After verification, the ward nurse clicks the "Submit" button on the ward terminal, which automatically synchronizes the updated preoperative handover form to the current surgical handover form. Simultaneously, a handover notification is sent to the anesthesia preparation room terminal, preparing to receive the patient. When the patient arrives at the operating room (anesthesia is usually administered in the operating room), the anesthesia nurse scans the patient's wristband using the anesthesia preparation room terminal. Based on the patient's unique identifier, the nurse automatically retrieves and displays the preoperative handover form submitted by the ward terminal from the current surgical handover form. Together with the ward nurses, they verify the contents of the preoperative handover form to confirm that the patient's basic information, vital signs, intravenous access, etc., are consistent with the patient's actual condition. After verification, the anesthesia nurse clicks the "Submit" button on the anesthesia preparation room terminal. The anesthesia preparation room terminal automatically synchronizes the anesthesia nurse's medical ID, electronic screen handwritten signature, and other identity information to the current surgical handover form in the surgical anesthesia system.

[0031] Anesthesia nurses use the anesthesia preparation room terminal to obtain the anesthesia handover form based on the patient's unique identifier. They update the form with information such as vital signs, tubing management, and nerve blocks based on the actual anesthesia progress, automatically synchronizing the updated form to the current surgical handover form. After anesthesia, they send a handover notification to the operating room terminal, preparing to receive the patient. Operating room nurses use the terminal to scan the patient's wristband to obtain their unique identifier. They then retrieve the anesthesia handover form based on this identifier and, together with the anesthesia nurses, verify and update the form according to the patient's current condition. After verification, the operating room nurses click the "Submit" button on the terminal, which automatically synchronizes their medical ID, electronic signature, and other identification information to the current surgical handover form in the surgical anesthesia system.

[0032] Operating room nurses retrieve the postoperative handover form using the patient's unique identifier via the operating room terminal. Based on the patient's actual surgical condition, they update the information on the postoperative handover form, such as vital signs, tubing management, and postoperative care arrangements, automatically synchronizing the updated form to the current surgical handover form. After surgery, they send a handover notification to the recovery room terminal, preparing to receive the patient. Recovery room nurses use the recovery room terminal to scan the patient's wristband, obtain the patient's unique identifier, retrieve the postoperative handover form based on this identifier, and, together with the operating room nurses, verify and update the information on the preoperative handover form according to the patient's current condition. After verification, the recovery room nurses click the "Submit" button on the recovery room terminal, which automatically synchronizes the recovery room nurses' medical ID, electronic handwritten signature, and other identification information to the current surgical handover form in the surgical anesthesia system.

[0033] Recovery room nurses retrieve the recovery room handover form using the patient's unique identifier via the recovery room terminal. Based on the patient's actual recovery progress, they update the form with information such as vital signs, tubing management, post-operative care, and whether the analgesia pump is set. The updated handover form is automatically synchronized to the current surgical handover form in the anesthesia system. Once the patient meets the recovery criteria, a handover notification is sent to the ward terminal, preparing to receive the patient back to the ward. Ward nurses scan the patient's wristband using the ward terminal to obtain the patient's unique identifier. Using this identifier, they retrieve the recovery room handover form and, together with the recovery room nurses, verify and update the information on the handover form based on the patient's current condition. After verification, the ward nurses click the "Submit" button on the ward terminal, which automatically synchronizes their medical ID, electronic signature, and other identification information to the current surgical handover form in the anesthesia system. This completes the entire data loop, ensuring consistent and traceable data throughout the process.

[0034] In addition, if the actual patient situation is inconsistent with the data on the handover form provided by the transferring party, the transferring party shall verify the information with both parties and then correct it to the latest and most accurate information.

[0035] This invention provides a closed-loop surgical handover system based on intelligent terminals, realizing an in-hospital handover process where surgical patients are transferred sequentially from the ward to the anesthesia preparation room, operating room, and post-anesthesia recovery room, before returning to the ward. By standardizing the handover process through handover paths and directions determined by surgical information, the system reduces information omissions and promotes continuity and completeness. The comprehensive handover content extracted from historical records, combined with a handover form based on patient surgical information, ensures detailed patient records while reducing redundant entries, facilitating refined management of handover information and ensuring accurate and smooth handover processes. Furthermore, the system ensures accountability by configuring mutually exclusive modification permissions for the handover form between the transferring and receiving parties, reducing adverse events related to surgical handover and supporting the traceability of handover information.

[0036] In a second embodiment of the present invention, based on a further optimization of the first embodiment, the handover item module maps handover items from a preset mapping table constructed based on multiple mapping rules according to surgical information and preoperative nursing information, wherein the multiple mapping rules include: The first mapping rule is configured to map postoperative care information derived from surgical information as handover items; The second mapping rule is configured to map preoperative nursing information, which continues as postoperative nursing information in the handover path, into handover items. The third mapping rule is configured to map preoperative nursing information that will be intervened by surgical information as a handover item.

[0037] Specifically, the handover items that need to be verified are used to ensure patient transport safety and continuity of care. Currently, it is difficult to classify the handover items in surgical handover forms using a unified technical classification standard. In this embodiment, the handover management dimensions used in historical paper surgical handover forms are statistically classified by department. Therefore, the handover system presets a handover mapping table based on the statistical classification results to represent the derivative relationship between surgical information and postoperative nursing information. That is, new postoperative nursing information may be generated after the surgical procedure is performed. For example, if endotracheal intubation occurs during the operation, airway-related handover items need to be added under the tube management dimension in the operating room handover form and the recovery room handover form: endotracheal intubation, tracheostomy cannula; and the continuation of preoperative nursing information in the handover path to the postoperative period. For example, the indwelling needle usually placed on the back of the patient's hand is present throughout the entire handover path; and the intervention relationship of surgical information on the removal, replacement, and modification of preoperative nursing information, such as the removal of a double-J stent through day surgery after kidney stone surgery. By analyzing the statistical patterns of surgical handover forms, a standardized mapping table was used to map complex surgical and nursing information into unified handover items, thus achieving automatic generation and adaptation of handover items.

[0038] Furthermore, based on the mapping and handover items of surgical information and preoperative nursing information, including: Structured clinical text is extracted from surgical information and preoperative nursing information, and the clinical text terminology is standardized into terminology text. Perform a full character match between the terminology text and the preset mapping table. If a match is found, retrieve the corresponding handover item. If the full character match fails, then a similarity match is performed based on the term text, and the intersection with the highest similarity is taken as the intersection. If a similarity match fails, the text of the failed term is marked as an item to be mapped, and a manual supplementary suggestion is generated.

[0039] Specifically, when mapping handover items, the module first performs structured parsing of clinical text records of surgical information and preoperative nursing information through keyword matching and syntactic analysis. This extracts clinical text including surgical type, surgical subject, and surgical procedure. For example, from "patient undergoes laparoscopic cholecystectomy under general anesthesia," it extracts clinical text such as "general anesthesia," "laparoscopy," and "cholecystectomy." For clinical text records of preoperative nursing information, it extracts clinical text including nursing measures and nursing sites. For example, from "patient had an indwelling needle inserted into the back of his left hand," it extracts clinical text such as "back of left hand" and "indwelling needle." The extracted clinical text is then compared with a standard terminology database. If a clinical text successfully matches a variant of a standard term in the database, the clinical text is replaced with the corresponding terminology text. The standard terminology database includes multiple sub-databases, such as a surgical terminology database and a nursing terminology database. Each sub-database stores the correspondence between clinical text and its synonyms, abbreviations, colloquial expressions, and variant forms with the terminology text.

[0040] The standardized terminology text is then precisely matched character-by-character with a pre-defined mapping table. This table uses a key-value pair structure, where the key is the standard terminology text and the value is the corresponding list of handover items. A hash lookup algorithm quickly locates a key in the pre-defined mapping table that is identical to the standard terminology text; if one exists, the corresponding handover item is retrieved directly. If a full-character match fails, the semantic similarity between the terminology text and all keys in the pre-defined mapping table is calculated. Keys with semantic similarity greater than a similarity threshold are selected, and the handover item corresponding to the key with the highest semantic similarity is chosen. If the semantic similarity between the terminology text and all keys is less than or equal to the similarity threshold, the terminology text is marked as an item to be added, and a prompt message is displayed on the terminal interface. Nursing staff review this information and fill it in the "Other" field. After submitting the departmental handover form, management personnel review it again to determine whether to add it to the mapping table. This ensures that nursing information recorded by different medical staff can be accurately understood and uniformly managed by the system, improving the accuracy of handover item extraction and matching.

[0041] Furthermore, a preset mapping table is constructed based on the first mapping rule, including: Obtain preoperative and postoperative nursing information corresponding to historical surgical handover forms; Extract the handover items from historical surgical handover forms and remove the preoperative and postoperative nursing information corresponding to the same handover item; Calculate the difference between the remaining postoperative nursing information and the preoperative nursing information to obtain the postoperative derivative nursing information, and obtain the corresponding derivative handover items in the historical surgical handover form for the derivative nursing information; Obtain surgical information corresponding to historical surgical handover forms; establish a mapping relationship between surgical information and derived handover items.

[0042] Specifically, historical surgical handover forms for multiple patients are obtained from the hospital information system. At the same time, historical surgical information, historical preoperative nursing information, and historical postoperative nursing information corresponding to the historical surgical handover forms are obtained. The correspondence between this information and the handover items is analyzed by combining the experience of nursing staff and historical mapping tables. Taking a patient undergoing laparoscopic cholecystectomy as an example, natural language processing technologies such as keyword matching and syntactic analysis are used to retrieve surgical clinical texts such as "laparoscopic cholecystectomy," "right upper quadrant," and "general anesthesia" from historical surgical information. Historical preoperative nursing information includes "blood pressure monitoring 120 / 80 mmHg" and "heart rate monitoring 75 bpm"; historical postoperative nursing information includes "blood pressure monitoring 110 / 70 mmHg," "heart rate monitoring 70 bpm," and "drainage tube placed on the right abdominal wall, drainage fluid is clear"; correspondingly, historical surgical handover forms include historical handover items such as "blood pressure" and "heart rate" under the "vital signs" handover management dimension, and historical handover items such as "abdominal drainage tube" under the "tube management" handover management dimension.

[0043] The system retrieves historical handover items such as "blood pressure" and "heart rate," and removes the corresponding historical preoperative and postoperative nursing information. Specifically, it removes preoperative and postoperative "blood pressure monitoring" and "heart rate monitoring," leaving different historical handover items. For these remaining items, the system calculates the difference between them to identify nursing information present in the postoperative nursing information but absent in the preoperative nursing information. This information is considered new nursing information derived from the surgical procedure, and its corresponding historical handover item is recorded as a derived handover item. Finally, the surgical clinical text is combined to obtain "(laparoscopic cholecystectomy, general anesthesia, right upper quadrant)," which is then mapped to the derived handover item "abdominal drainage tube" using key-value pairs. This mapping relationship is stored in a pre-defined mapping table. In another embodiment, separate data tables can be created for historical surgical information and historical handover items, and a data table can be created for the mapping relationship between different combinations of surgical information and different combinations of handover items. The set mapping relationship is realized through a relational database formed by multiple tables. By analyzing the nursing information derived after surgery, newly added nursing information after the surgery can be automatically obtained as handover items, which helps to improve the completeness of the preset mapping table.

[0044] Furthermore, a preset mapping table is constructed based on the second mapping rule, including: Extract the handover items from historical surgical handover forms and obtain the preoperative and postoperative nursing information corresponding to the handover items; Whether information is considered as continuing care information is determined based on whether the similarity between preoperative and postoperative care information is greater than a preset continuing information threshold. Establish a mapping relationship between preoperative nursing information that is determined to be continuing care information and handover items.

[0045] Specifically, natural language processing techniques such as keyword matching and syntactic analysis are used to extract historical handover items from historical surgical handover forms, obtaining historical preoperative and postoperative nursing information corresponding to each historical handover item. In this embodiment, historical preoperative and postoperative nursing information with identical characters is first extracted by full character matching. For example, under the "tube management" handover management dimension, the historical handover item "peripheral vein" corresponds to the historical preoperative and postoperative nursing information "right dorsal vein indwelling needle." However, the recorded text of nursing information for the same handover item by medical staff before and after surgery may differ. Therefore, preferably, the semantic similarity between historical preoperative and postoperative nursing information is calculated. Historical preoperative and postoperative nursing information with a semantic similarity greater than a preset continuation information threshold is obtained, indicating that they are the same nursing information and recorded as continuation nursing information. The corresponding historical preoperative nursing information is then mapped to the corresponding historical handover item using the aforementioned key-value pairs or relational data. By analyzing which preoperative nursing care needs to be continued after surgery, handover items can be extracted based on the continuity and consistency of nursing information, which helps improve the completeness of the preset mapping table.

[0046] Furthermore, a preset mapping table is constructed based on the third mapping rule, including: Extract handover items from historical surgical handover forms to obtain preoperative and postoperative nursing information corresponding to the same handover item; obtain preoperative nursing information that differs from postoperative nursing information. Obtain surgical information corresponding to historical surgical handover forms; establish a mapping relationship between surgical information and handover items corresponding to preoperative nursing information.

[0047] Specifically, historical handover items are extracted from historical surgical handover forms. Simultaneously, historical surgical information, preoperative nursing information, and postoperative nursing information corresponding to these forms are obtained. Natural language processing technologies such as keyword matching and syntactic analysis are used to extract key information from the historical surgical information, including the surgical name, surgical site, and anesthesia method. Historical preoperative and postoperative nursing information corresponding to the same historical handover item are obtained. Through character matching or by calculating the semantic similarity between the two information, historical preoperative nursing information that fails to match or has a semantic similarity less than a preset intervention threshold is identified. This indicates that the information has been removed, replaced, or adjusted due to intervention in surgical information such as the surgical procedure. For example, a double-J stent may be removed via day surgery after kidney stone surgery, or the patient's skin condition may change from normal before surgery to postoperative local redness due to prolonged surgery. Historical surgical information that has influenced historical preoperative nursing information is obtained, along with the historical handover items corresponding to the altered preoperative nursing information. A mapping relationship is established between historical surgical information and historical handover items using the aforementioned key-value pairs or relational data. By analyzing the intervention relationships between surgical information and preoperative nursing information, such as removal, replacement, or adjustment, the handover items affected by surgical information can be identified, which helps improve the integrity of the pre-set mapping table.

[0048] Furthermore, the handover module retrieves historical surgical handover forms based on surgical information, including: Extract the surgical name and preoperative diagnosis from the current surgical information, and obtain historical surgical handover forms where the surgical name and preoperative diagnosis results are the same. Obtain surgical information that has an impact on preoperative nursing information and convert it into a first vector; calculate the first similarity between the first vector of the current patient and the first vector of the corresponding patient in the historical surgical handover form; Extract the second vector representing the integrity of the patient's body surface from the preoperative nursing information, and calculate the second similarity between the second vector of the current patient and the second vector of the corresponding patient in the historical surgical handover form; If both the first similarity and the second similarity are greater than the corresponding preset threshold, the historical surgical handover form with the highest first similarity is obtained for extracting handover items.

[0049] Specifically, to make the handover item recommendations more personalized and valuable, the handover item module intelligently retrieves historical surgical handover forms most similar to the current patient based on surgical information as a reference. In this embodiment, firstly, based on the surgical name and preoperative diagnosis results extracted from the current surgical information, historical surgical handover forms with the same surgical name and preoperative diagnosis are initially screened from the historical database. Then, according to the mapping table formed by the third mapping rule, medical information representing interventional surgical operations such as removal, replacement, and alteration, such as surgical name, surgical site, and surgical procedure, is extracted from the current surgical information and converted into a first vector through one-hot encoding, word embedding model, etc. Simultaneously, information words representing the patient's preoperative state, such as skin condition, pressure ulcer risk, and existing tubing information, are extracted from the preoperative nursing information and converted into a second vector through one-hot encoding, word embedding model, etc. The system calculates the cosine similarity between the current patient and multiple historical cases on the aforementioned two vectors. By comparing the directional similarity between the vector corresponding to the current patient and the vector corresponding to the historical case, historical cases with a cosine similarity greater than a preset threshold are identified. Historical surgical handover forms with cosine similarities in both vector types exceeding their respective preset thresholds are selected as candidates. For each candidate historical surgical handover form, the one with the highest cosine similarity is chosen, and the handover items are extracted from it. This allows for the acquisition of surgical handover forms from historical cases with similar surgical handover processes to the current patient as a reference, improving the accuracy of constructing surgical handover forms.
