Description

Technical Field

[0001] The present invention relates to a warning score output system and a warning score output method that output a plurality of patients, for example, in order according to severity (risk).

Background Art

[0002] Conventionally, as a tool for predicting patient deterioration, methods such as the Early Warning Score (hereinafter simply abbreviated as "EWS") have been proposed. EWS is described in, for example, Patent Document 1.

[0003] EWS is a score obtained by scoring each of the respiratory rate (RR), oxygen saturation (SpO2), body temperature (BT), systolic blood pressure (ABPs), and heart rate (HR) acquired every unit time based on a predetermined standard, and further summing them up. By sharing the EWS within the hospital, it becomes possible to quickly respond to the clinical risks of patients throughout the hospital.

[0004] In addition, Patent Documents 2 to 4 describe techniques for sorting patients according to a warning score indicating the severity (risk) of patients such as EWS and displaying them in a list, or sorting patients by color and displaying them in a list. This enables medical staff to immediately recognize the patients who should be treated preferentially.

[Modes for carrying out the invention]

[0012] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0013] <1> System Configuration Figure 1 is a block diagram showing an example configuration of a hospital system 10 to which the warning score display system of this embodiment is applied. Note that the warning score display system of this embodiment is not limited to the hospital system 10 configured in Figure 1, but can be applied in various forms within a hospital. Furthermore, the warning score display system of this embodiment can be configured not only within a hospital, but also, for example, across a patient's home and a medical institution such as a hospital that provides treatment for that patient.

[0014] The hospital system 10 in Figure 1 includes biological information measuring devices 11a, 11b, and 11c, a server 12, and terminals 13a, 13b, and 13c.

[0015] The biological information measuring devices 11a, 11b, and 11c measure biological information such as respiratory rate (RR), oxygen saturation (SpO2), body temperature (BT), systolic blood pressure (ABPs), and heart rate (HR) for each patient in the hospital room. The measured biological information is sent to the server 12.

[0016] Furthermore, the biological information measured by the biological information measuring devices 11a, 11b, and 11c may be sent to the server 12 via a spot check monitor (not shown), etc. Incidentally, the spot check monitor can aggregate the biological information obtained by the biological information measuring devices 11a, 11b, and 11c and send it to the server 12 or the terminal 13a of the electronic medical record system, etc. Also, the spot check monitor can calculate the EWS based on the biological information obtained by the biological information measuring devices 11a, 11b, and 11c and send the EWS along with the biological information.

[0017] Figure 2 shows an example of a display image shown on the display unit of the spot check monitor. In the example in Figure 2, the measured values ​​of vital signs, the score for each vital sign, and the EWS (Energy Warning System) calculated by summing these scores are displayed for a particular patient. The spot check monitor transmits this information to the server 12 or the like.

[0018] Server 12 aggregates and stores the vital signs and EWS data of each patient received from the vital signs measurement devices 11a, 11b, and 11c, as well as the spot check monitor. Server 12 also forms a list image for displaying the vital signs and EWS data of multiple patients. This list image is displayed on the display unit (not shown) of Server 12, as well as on the display units (not shown) of terminals 13a, 13b, and 13c.

[0019] Terminals 13a, 13b, and 13c are terminals installed in the hospital's higher-level systems such as the electronic medical record system, the nurses' station, and the emergency medical team, respectively. Terminals 13a, 13b, and 13c can access server 12 to receive a list image formed by server 12 and display it on their own display units (not shown).

[0020] In this way, the hospital system 10 measures the vital signs of each patient using the vital signs measuring devices 11a, 11b, and 11c, and the server 12 forms a list image containing the vital signs and EWS of multiple patients, and this list image can be displayed on multiple terminals 13a, 13b, and 13c within the hospital.

[0021] Figure 3 is a block diagram showing the configuration of the warning score display system 100 according to this embodiment.

[0022] The warning score display system 100 includes a warning score acquisition unit 101, a sorting unit 102, an image forming unit 103, a display unit 104, a storage unit 105, a confirmation operation unit 106, and a control unit 110. The control unit 110 controls the overall operation of the warning score display system 100. In other words, when each element of the warning score display system 100 operates in coordination, the control unit 110 controls the operation timing of each element.

[0023] The warning score acquisition unit 101 calculates each patient's EWS based on each patient's biological information. The method for calculating this EWS can be the same as known techniques described in Patent Documents 1-5, so a detailed explanation is omitted here.

[0024] The sorting unit 102 sorts multiple patients based on EWS scores, biometric information scores, and so on. For example, the sorting unit 102 sorts patients in descending order of EWS score.

[0025] The image forming unit 103 forms a list image by arranging multiple patients in the order sorted by the sorting unit 102. For example, it forms a list image in which patients with larger EWS are positioned higher or to the left. The list image includes patient-identifying information such as the patient's name, each patient's biological information, and each patient's EWS.

[0026] The display unit 104 displays a list image formed by the image forming unit 103.

[0027] In addition to the above configuration, the warning score display system 100 of this embodiment has a confirmation operation unit 106 that can accept confirmation operations from medical personnel regarding treatment for each patient. The confirmation operation unit 106 is embodied, for example, by a mobile terminal such as a smartphone carried by a medical personnel. Alternatively, the confirmation operation unit 106 can be embodied by a mouse or keyboard connected to the server 12. Furthermore, if the display unit 104 that displays the list image has a touch panel configuration, the confirmation operation unit 106 can be embodied by this touch panel. In other words, various operation input units that accept user operations can be applied as the confirmation operation unit 106.

[0028] When a medical professional performs a confirmation operation using the confirmation operation unit 106 to indicate that they have performed a procedure on a patient, a confirmation signal is sent from the confirmation operation unit 106 to the sorting unit 102 and the image forming unit 103.

[0029] When the sorting unit 102 receives a confirmation signal, it performs sorting processing in the list image, such as lowering the display order of the patient corresponding to the confirmation signal. When the image forming unit 103 receives a confirmation signal, it changes the treatment status in the list image. This sorting and changing of treatment status will be explained in detail later.

[0030] Here, the warning score acquisition unit 101, sorting unit 102, image forming unit 103, and control unit 110 each include a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), etc., as their main components. The CPU reads a program corresponding to the processing content from the ROM and loads it into the RAM, and in cooperation with the loaded program, the functions of the warning score acquisition unit 101, sorting unit 102, image forming unit 103, and control unit 110 are realized.

[0031] In this embodiment, the functions of the warning score acquisition unit 101, sorting unit 102, image forming unit 103, storage unit 105, and control unit 110 are implemented by the server 12. The display unit 104 is provided on the server 12 and terminals 13a, 13b, and 13c. The confirmation operation unit 106 is implemented by a mouse, keyboard, mobile terminal, touch panel, etc., connected to the server 12, as described above.

[0032] However, the components constituting the warning score display system 100 are not limited to these. For example, the warning score acquisition unit 101 may be implemented by a spot check monitor (not shown), and the image forming unit 103 may be provided in terminals 13a, 13b, and 13c.

[0033] <2> List of images according to the embodiment Next, the list image formed by the image forming unit 103 of this embodiment and displayed on the display unit 104 will be explained using Figures 4-9.

[0034] As shown in Figure 4, the list image includes patient identification information for each patient, such as patient name, patient ID, gender, and age. To the right of each patient identification information, the department and bed number where the patient is hospitalized are displayed, and further to the right, the date and time of measurement of the vital signs are displayed.

[0035] Furthermore, to the right of the measurement date and time, the EWS for each patient is displayed. To the right of that, the vital signs information for each patient is displayed. In the example in Figure 4, the vital signs information displayed includes respiratory rate, SpO2, systolic blood pressure, pulse rate, level of consciousness, and body temperature. The measured value is displayed in the upper section of each vital sign information, and the score is displayed in the lower section. The EWS and the scores for each vital sign information are calculated by the warning score acquisition unit 101. In the example in Figure 4, the oxygen administration status is displayed next to the SpO2.

[0036] The display areas for EWS and biometric information scores are color-coded according to their values. For example, the EWS display area is red if the EWS score is 7 or higher, orange if it is between 5 and 6, green if it is between 1 and 4, and colorless if it is 0. The display area for biometric information scores is red if the score is 3, orange if it is 2, green if it is 1, and colorless if it is 0.

[0037] Furthermore, the list image displays warnings corresponding to each patient. In the example in Figure 4, warnings such as "Please attach the vital signs monitor" are displayed in the columns for Patient A and Patient B, and a warning such as "1 hour and 11 minutes have passed" is displayed in the column for Patient D. In this embodiment, these warnings are displayed in a blinking manner. In other words, the list image alternates between a state where the warning is lit up, as shown in Figure 4, and a state where the warning is off (not shown). This makes the warnings stand out. Also, when the warning is off, information that is hidden when the warning is lit becomes visible, thus effectively increasing the amount of information that can be displayed.

[0038] In addition to these, the list image of this embodiment is provided with a treatment status display area 201. The treatment status display area 201 displays the treatment status for each patient. The image forming unit 103 changes the display in the treatment status display area 201 based on the size of the EWS and the operation status of the confirmation operation unit 106.

[0039] In this embodiment, for patients with an EWS size of 5 or more, the status "Confirmed" is displayed in the treatment status display area 201. Healthcare professionals can identify patients who require treatment by looking at this "Confirmed" status.

[0040] The term "treatment" refers to, for example, performing some kind of medical procedure on a patient. This includes checking the patient's condition. The medical professional who performed the treatment on the patient, or the medical professional who received notification that the treatment has been performed, inputs that the treatment has been completed by operating the confirmation unit 106. As mentioned above, the confirmation unit 106 may be a mobile terminal or a touch panel, but in this embodiment, we will explain using the case where it is a mouse and keyboard connected to the server 12 as an example.

[0041] Medical professionals can input that a procedure has been completed by selecting the "Confirm" button displayed on the display unit 104 using the mouse. Specifically, they move the cursor to the "Confirm" button and click it.

[0042] For example, if a healthcare professional selects the "Confirm" button displayed in the treatment status display area 201 corresponding to patient A, as shown in Figure 5, the image forming unit 103 changes patient A's treatment status to "Confirmed," as shown in Figure 6.

[0043] Next, after a predetermined time (e.g., 5 minutes) has elapsed since changing the treatment status of patient A to "confirmed," the display ranking of patient A is lowered, as shown in Figure 7. In other words, the display position of patient A, whose treatment has been completed, is moved to a less conspicuous position. In practice, this change in position is performed by the sorting unit 102 sorting the display order of patients whose confirmation operation has been received, lowering their display order.

[0044] The display position of patients whose treatment has been confirmed can be changed (lowered) as appropriate. However, it is not advisable to change it to an extremely inconspicuous position. For example, it could be lowered to a position equivalent to the position obtained by subtracting a predetermined number from the EWS (e.g., subtracting 3). Incidentally, this subtraction process is performed solely for the purpose of changing the position, and does not actually reduce the displayed numerical value.

[0045] Note that while Figure 7 shows an example where the display rank of patient A, whose treatment has been confirmed, is lowered, as shown in Figure 8, the "Confirm" button for patient A, whose treatment has been confirmed, can also be removed without changing the display rank. The point is to change the status display in the treatment status display area 201 so that healthcare professionals can recognize that treatment has been completed for patients who needed it. However, as shown in Figure 7, lowering the display rank of patients whose treatment has been confirmed makes it easier for healthcare professionals to grasp the priority of which treatments should be performed.

[0046] Furthermore, as shown in Figure 9, the EWS column in the list image may display the previous EWS in addition to the current EWS. Also, when a healthcare professional selects a desired patient from the list image, a trend graph of the selected patient's biometric information may be displayed, as shown in Figure 10.

[0047] <3> Instructions for updating the list of images Figure 11 is a flowchart showing the update procedure performed when the list image is updated by the warning score display system 100.

[0048] The warning score display system 100, after measuring (inputting) biometric information in step S1, determines in step S2 whether each patient is at high risk (severity). In practice, the warning score acquisition unit 101 determines whether the risk is high based on the calculated EWS. For example, if the EWS is 5 or higher, it is determined that the risk is high. The criteria for determining whether the risk is high or not can be set by the medical institution operating the system.

[0049] If the warning score acquisition unit 101 determines that the risk is high, it moves to step S3 and assigns a status flag to the patient; if it determines that the risk is not high, it moves to step S4 and does not assign a status flag to the patient. A status flag is a flag that indicates that treatment is necessary in the treatment status display area 201. Specifically, a "Confirm" button is displayed for patients who have been assigned a status flag, and the "Confirm" button is not displayed for patients who have not been assigned a status flag.

[0050] In the following step S5, the image forming unit 103 determines whether or not there are past valid measurement values. Here, past valid measurement values ​​refer to biological information that is older than a predetermined time (for example, 24 hours). For example, if there is biological information that is older than 24 hours from the time of measurement, it is determined that there are past valid measurement values.

[0051] If the image forming unit 103 determines that there are past valid measurement values, it proceeds to step S6 and displays the past valid measurement values ​​as the previous values, as well as the current measurement values ​​as the current values. This prevents outdated biological information from being confused with newer biological information and displayed incorrectly. Incidentally, in step S6, it is not necessary to display past valid measurement values. On the other hand, if it determines that there are no past valid measurement values, it proceeds to step S7 and displays the current measurement values ​​as the current values.

[0052] In the following step S8, the image forming unit 103 waits until it is time to update the screen, and when it is time to update the screen, it moves to step S9 and displays the list images based on steps S6 and S7 on the display unit 104. Here, the screen update timing may be when new biological information is input, when a new patient who should be given a warning appears, or at a predetermined interval (for example, once every 5 minutes).

[0053] <4> Control operation of the treatment status Figure 12 is a flowchart illustrating the control operation of the processing status.

[0054] If a patient with status 1 (requiring treatment) is identified in step S10 (i.e., a patient with a status flag is identified), the warning score display system 100 proceeds to step S11 and displays "Confirmed" on the screen. Specifically, "Confirmed" is displayed in the status display area 201 of the patient with the status flag (see Figure 4).

[0055] If the confirmation operation is accepted in the following step S12, the process proceeds to step S13 to change the patient's status to status 2 (procedure completed), and in step S14, "Confirmed" is changed to "Confirmed" (see Figure 6).

[0056] In the following step S17, if it is determined that a predetermined time (for example, 5 minutes) has elapsed, the process moves to step S18, where the patient's status is changed to status 0 (no treatment required), and in step S19, "Confirmed" is deleted (see Figures 7 and 8).

[0057] In the following step S20, it is determined whether a predetermined time has elapsed. This predetermined time can be, for example, one hour or six hours. This predetermined time should be set appropriately considering the patient's risk if no treatment is performed.

[0058] Until a predetermined time has elapsed, step S22 displays instructions and the validity period on the screen. For example, instructions such as "Remeasure within 52 minutes" (see Figure 5) are displayed. Once the predetermined time has elapsed (i.e., if remeasurement is not performed within the time indicated in the instructions), the system proceeds to step S21 and begins issuing a warning.

[0059] Next, in step S23, the status is changed to status 1 (requires treatment), and the process returns to step S11. In this way, the image forming unit 103 changes the treatment status display back to "confirmed," which prompts treatment, after a period of time has elapsed since the treatment status display was set to "confirmed" or cleared. This allows for the display to prompt medical personnel to perform treatment again, even for patients who have already received treatment from a medical professional, after a predetermined amount of time has elapsed, thereby preventing patients from being left unattended after treatment.

[0060] As an option, steps S15 and S16 may be added between steps S14 and S17. In step S15, the status of all patients who have been confirmed prior to this confirmation is changed to status 0. In step S16, the screen display is changed based on the status in step S15.

[0061] Steps S15 and S16 are effective when there are so many patients with status 1 (requiring treatment) that they cannot all fit on the screen. In other words, steps S15 and S16 allow you to lower the priority of all patients except those recently checked (treated) by forcibly changing their status to 0 (no treatment needed) without waiting for a predetermined amount of time to pass, thereby displaying other patients who require treatment at the top.

[0062] <5> Example of treatment status This section provides a detailed explanation of the treatment status displayed in the treatment status display area 201.

[0063] In this embodiment, as shown in Figure 4-9, the display of the treatment status display area 201 is changed according to the treatment status for each patient.

[0064] Specifically, as shown in Figure 13, if treatment is required for the patient, "Confirmed" is displayed; when a confirmation operation indicating that the treatment is complete is performed, "Confirmed" is displayed; and after a predetermined time has elapsed, "Confirmed" is removed.

[0065] Figure 14 shows another example of the display in the treatment status display area 201. In the example in Figure 14, "Confirm" is displayed when treatment is required for the patient. When a confirmation operation is performed to indicate that the treatment is complete, the date and time of the confirmation operation and the name of the healthcare professional who performed the confirmation operation are displayed. After a predetermined time has elapsed, the frame surrounding the date, time and name disappears. In this way, healthcare professionals viewing the list image can recognize not only whether the treatment is complete or not, but also who performed the treatment and when.

[0066] Figure 15 shows another example of the display in the treatment status display area 201.

[0067] The display example in Figure 15 shows a case where the patient's treatment status includes status 0 (no treatment needed), status 1 (treatment required), status 2 (treatment completed), and status 3 (treatment started). If a patient is determined to be status 1, the treatment status display area 201 for that patient will display the buttons "Check List," "Start Treatment," and "Complete Treatment," as shown in Figure 15A. When the "Check List" button is selected by a healthcare professional, the "Check List" button will disappear and the "Start Treatment" and "Complete Treatment" buttons will be displayed, as shown in Figure 15B.

[0068] In addition to the "procedure completed" confirmation operation by the medical professional, a "procedure started" confirmation operation is also entered, so the warning score display system 100 can also understand that the medical professional is in the middle of a procedure.

[0069] <6> Example of sorting patients in a list of images The list image displayed by the warning score display system 100 of this embodiment can be said to control the level of attention given to healthcare professionals by the status in the treatment status display area 201 and the sorting order of the patients. Here, we will explain in detail how patients are sorted in the list image.

[0070] In this embodiment, four methods are presented for sorting (displaying order) patients in a list image. Figures 16-19 are diagrams illustrating each sorting method 1-4, and are simplified representations of the list images exemplified in Figures 4-9, etc. In the list images of Figures 16-19, multiple patient information is arranged from top to bottom. Also, the treatment status display area, EWS, scores for each biological information, and warnings are displayed from left to right.

[0071] ●(Sort method 1) Patients are sorted according to the priority order of Treatment Status > EWS Subscore > Warning. Figure 16 is a schematic diagram showing an example of a list image sorted by sorting method 1.

[0072] ●(Sort method 2) Patients are sorted by priority: Treatment Status > Warning > EWS Subscore. Figure 17 is a simplified diagram showing an example of a list image sorted by sorting method 2. In Figure 17, for example, the 8th patient from the top has an EWS of 1 and a warning of "6 hours elapsed" (i.e., 6 hours have passed since the time for remeasurement). On the other hand, the 9th patient from the top has an EWS of 5 and a warning of "Remeasure within 51 minutes". Therefore, although the 8th patient has a lower EWS than the 9th patient, it is displayed higher than the patient with a higher EWS because the importance of the warning is higher.

[0073] ●(Sort method 3) Patients are sorted in the following order of priority: Treatment Status > EWS (4 classifications: High, Medium, Low-Medium, Low) > Warning > EWS Subscore. Figure 18 is a simplified diagram showing an example of a list image sorted by sorting method 3.

[0074] ●(Sort method 4) Patients are sorted in the following order of priority: Treatment Status > EWS (2 classifications: Low-Medium or higher, Low) > Warning > EWS Subscore. Figure 19 is a simplified diagram showing an example of a list image sorted by sorting method 4.

[0075] While four sorting methods are presented here, the sorting methods of the present invention are not limited to these. For example, factors such as the oldest measurement time may be added as sorting elements. Specifically, from the perspective that patients with older measurement times are at higher risk of changes in their condition, it is desirable to rank patients with older measurement times higher. In addition, while treatment status is used as the highest-level sorting element, higher-level elements may also be added.

[0076] <7> How to display warnings This section provides a detailed explanation of how to display warnings in a list of images.

[0077] Figure 20 is a flowchart showing the procedure for displaying a warning according to this embodiment. As shown in Figure 20, when the image display update timing is reached in step S30, the image forming unit 103 moves to step S31 to determine whether or not a high-risk patient is present, and if a high-risk patient is present, it moves to step S32 to display the warning content on the screen. This allows for immediate display of a warning, such as "Please connect the vital signs monitor," when a high-risk patient, such as one with an EWS score of 7 or higher, is present.

[0078] In response to this, the image forming unit 103 proceeds to step S33 if no high-risk patients are present. In step S33, it determines whether or not there are patients at risk, and if not, it proceeds to step S37 and does not issue a warning.

[0079] On the other hand, if there are patients at risk, the system proceeds to step S34 and waits until a predetermined time has elapsed. This predetermined time is, for example, 1 hour for moderately risky patients and 6 hours for low-risk patients. Once the predetermined time has elapsed, the system proceeds to step S35 and displays a warning message on the screen. Furthermore, in the following step S36, the patient's status is changed to status 1 (requires treatment).

[0080] Here, for patients at medium or low risk, monitoring is required once every hour or once every 4-6 hours. If the next set of biometric data is not entered after that time, a warning is issued through the processing in steps S34-S35.

[0081] In the embodiment described above, low-risk patients with an EWS score of 0-4 were not subject to "treatment." However, in the processing procedure shown in Figure 20, if the recommended measurement frequency, such as once every 6 hours, is exceeded, a warning is issued and the patient is changed to a "treatment-requiring" patient in step S36.

[0082] Figure 21 is a flowchart showing the display procedure for another method of displaying a warning. When the image display update timing is reached in step S40, the image forming unit 103 moves to step S41 to determine whether the risk has worsened compared to the previous value, based on the EWS and biological information scores (subscores). If a patient's risk has worsened compared to the previous value, the unit moves to step S42 to display a warning on the screen. For example, a warning such as "It has worsened compared to last time" may be displayed. Alternatively, a warning such as "EWS has risen sharply" may be displayed.

[0083] <8> summary As described above, according to this embodiment, the warning score display system 100 includes a warning score acquisition unit 101 that obtains a warning score based on the patient's biological information, a sorting unit 102 that sorts multiple patients based on the warning score, an image forming unit (image forming unit 103) that forms a list image in which the multiple patients are arranged in the order sorted by the sorting unit 102, and an output unit (display unit 104) that outputs the list image. The image forming unit (image forming unit 103) forms a treatment status area (treatment status display area 201) in the list image in which the treatment status for each patient can be described.

[0084] Furthermore, according to this embodiment, the steps include forming a treatment status (such as "Confirmed") on the list image indicating whether or not treatment is necessary for the patient; receiving a treatment confirmation signal from a medical professional to the patient (a signal from the confirmation operation unit 106); and changing the treatment status based on the treatment confirmation signal (for example, changing "Confirmed" to "Confirmed").

[0085] This will allow healthcare professionals to accurately and easily determine the priority of patient treatment from a list of images.

[0086] The embodiments described above are merely examples of how the present invention can be implemented, and the technical scope of the present invention should not be limited by them. In other words, the present invention can be implemented in various ways without departing from its gist or its main features.

[0087] In the list image, specific patients may be pinned to a fixed position. For example, a specific patient may be pinned to the top of the list regardless of their status flag.

[0088] The list image may be configured to display only patients requiring treatment. Alternatively, the list image may display the number of patients requiring treatment.

[0089] Depending on the permissions of the healthcare professional logged into the system, the range of patients displayed in the list image may be narrowed.

[0090] If there is a delay in treatment by healthcare professionals, the elapsed time may be highlighted in the list image (countdown display or pop-up display). The color and shape of the "Confirm" button may also be changed according to the elapsed time. This will help to encourage healthcare professionals to take action.

[0091] Warnings may be displayed not only visually but also audibly. In this case, a notification function may be provided if the audible level is too low.

[0092] In the above-described embodiment, a treatment status display area 201 was formed to the left of the EWS, and the treatment status for each patient was described in the treatment status display area 201. However, the present invention is not limited to this, and essentially, it is sufficient to form a treatment status area in the list image in which the treatment status for each patient can be described, and the position of the treatment status area is not limited to the position in the above-described embodiment.

[0093] Furthermore, while the above-described embodiment mentions the use of the words "Confirmed" and "Confirmed" to describe the treatment status, the present invention is not limited to this. For example, the treatment status may be described using words other than those used in the embodiment, such as "Treatment Required" or "Treatment Completed." Moreover, the method of describing the treatment status is not limited to words; it may also be described by, for example, color or brightness. For example, the column for patients requiring treatment and the column for patients whose treatment has been completed may be distinguished by color or brightness. In this case, the treatment status area can be said to be a display column for each patient.

[0094] The above embodiment described the case where EWS (Early Warning Score) was used as the warning score, but the same procedure can be performed when using NEWS (National Early Warning Score), EWS (Early Warning Score), SOFA (Sequential Organ Failure Assessment), qSOFA (quick SOFA), APACHE, etc. as the warning score. In short, any score that represents the severity (risk) of the patient's condition should be used as the warning score.

[0095] Furthermore, while the above-described embodiment described the application of the present invention to a warning score display system 100, the present invention is not limited to this and can also be applied to systems that print a list image based on warning scores, systems that record a list image based on warning scores, or systems that send a list image based on warning scores via email or the like. In short, by changing the display unit 104 in Figure 3 to a printing unit, a recording unit, or a transmission unit, a warning score printing system, a warning score recording system, or a warning score transmission system can be realized, and the same effects as the warning score display system of the above-described embodiment can be obtained in these as well. In other words, the present invention is widely useful as a warning score output system and a warning score output system that outputs a list image of multiple patients based on warning scores.

[0096] In the warning score display system 100 described above, the list images are usually displayed continuously in real time. However, when printing, recording, or transmitting the list images, the output timing of the list images may be, for example, when the list images are updated, or at periodic intervals. In this case, it is preferable to print, record, or transmit the output timing along with the list images.

[0097] In this specification, all instances of "warning score" may be interpreted as "alert score." [Industrial applicability]

[0098] The present invention is widely applicable to a warning score display system and a warning score display method that display a list image including EWS for multiple patients. [Explanation of symbols]
