[Modes for carrying out the invention]

[0011] Embodiments of this disclosure will be described in detail below with reference to the drawings. These embodiments are not intended to limit the technology of this disclosure.

[0012] The information processing device of this embodiment is a device that outputs evaluation indicators of biological information values ​​during a treatment period related to medical procedures on living organisms. In this embodiment, as a specific example, the case in which the information processing device outputs evaluation indicators of biological information values ​​of a patient during surgery will be described.

[0013] Figure 1 shows a block diagram illustrating an example of the configuration of the information processing device 10 of this embodiment. As shown in Figure 1, the information processing device 10 of this embodiment comprises a control unit 20, a storage unit 22, a communication interface unit 24, an operation unit 26, and a display unit 28. The control unit 20, storage unit 22, communication interface unit 24, operation unit 26, and display unit 28 are connected to each other via a bus 29, such as a system bus or a control bus, enabling the exchange of various types of information.

[0014] The control unit 20 of this embodiment controls the overall operation of the information processing apparatus 10. The control unit 20 is a processor and includes a CPU (Central Processing Unit) 20A. Further, the control unit 20 is connected to a storage unit 22, which will be described later. Note that the control unit 20 may include a GPU (Graphics Processing Unit).

[0015] The operation unit 26 is used for the user to input various kinds of information. The operation unit 26 is not particularly limited, and examples thereof include various switches, touch panels, touch pens, mice, and microphones for voice input. The display unit 28 displays information regarding evaluation indexes and the like. Examples of the display unit 28 include a liquid crystal display and an LED (Light Emitting Diode) display. Note that the operation unit 26 and the display unit 28 may be integrated into a touch panel display.

[0016] The communication I / F unit 24 communicates various kinds of information with devices outside the information processing apparatus 10 via a network (not shown) by wireless communication or wired communication.

[0017] The memory unit 22 includes a ROM (Read Only Memory) 22A, a RAM (Random Access Memory) 22B, and a storage unit 22C. The ROM 22A pre-stores various programs executed by the CPU 20A. The RAM 22B temporarily stores various data. The storage unit 22C stores information processing programs 30 executed by the CPU 20A, and other various information. In this embodiment, medical procedure information 32 is also pre-stored in the storage unit 22C. The medical procedure information 32 includes at least biometric information table values ​​representing the patient's biological information obtained from the patient during surgery. As will be described in detail later, the medical procedure information 32 in this embodiment includes biometric information values ​​representing multiple types of biological information. Furthermore, the medical procedure information 32 in this embodiment also includes other information related to the patient's condition during surgery. Examples of other information include administration information related to the administration of drugs to the patient. For example, the medical procedure information 32 is managed by storing biometric information for the same surgery in association with identification information for the same surgery. Storage 22C is a non-volatile memory unit, such as an HDD (Hard Disk Drive) or SSD (Solid State Drive).

[0018] In this embodiment, the medical procedure information 32 is described as being stored in the storage 22C of the memory unit 22, but the storage location of the medical procedure information 32 is not limited. For example, the medical procedure information 32 may be stored in a device outside the information processing device 10.

[0019] Furthermore, Figure 2 shows a functional block diagram of an example configuration of the information processing device 10 of this embodiment. As shown in Figure 2, the information processing device 10 comprises an acquisition unit 40, a duration derivation unit 42, an evaluation index derivation unit 44, and a display control unit 46. As an example, in the information processing device 10 of this embodiment, the CPU 20A of the control unit 20 executes an information processing program 30 stored in the storage 22C, so that the CPU 20A functions as the acquisition unit 40, the duration derivation unit 42, the evaluation index derivation unit 44, and the display control unit 46.

[0020] The acquisition unit 40 acquires medical procedure information 32, which includes biometric information values ​​representing the patient's biological information during the surgical period. The general flow of surgery for a patient is as follows: entering the operating room, initiation of anesthesia, intubation, commencement of surgery, completion of surgery, extubation, termination of anesthesia, and departure from the operating room. In this embodiment, the surgical period refers to the period from the commencement of surgery to the completion of surgery within the above flow. The definition of the surgical period is not limited to the above embodiment; for example, the surgical period may be defined as the period from the commencement of anesthesia to the termination of anesthesia, and it may also be configurable by the user of the information processing device 10.

[0021] Furthermore, the biological information values ​​acquired by the acquisition unit 40 may be the measured values ​​themselves output externally from the measuring device that measures the patient's biological information, or they may be values ​​obtained by processing the measured values. For example, they may be statistical values ​​(average, maximum, and minimum values, etc.) of the measured values ​​output from each of multiple measuring devices. In addition, time information during the surgical period is stored in association with the measured values. Note that the time information may be relative time, such as the elapsed time from the start of the surgical period, or it may represent absolute time, such as the system time.

[0022] The acquisition unit 40 outputs the acquired medical treatment information 32 to the duration derivation unit 42.

[0023] The duration deriving unit 42 derives the duration during which the biological information value remains within a numerical range associated with the type of biological information for a predetermined period of time. The medical treatment information 32 in this embodiment includes biological information values ​​representing multiple types of biological information. The types of biological information are not limited. For example, in the information processing device 10 of this embodiment, two levels of biological information types are adopted: a major category and subcategories (items) provided for each major category, and an evaluation index is derived for each subcategory (item). In this embodiment, two levels of biological information types are adopted, but this is not limited to this; there may be one level or three or more levels of biological information types.

[0024] As an example, five major categories of biological information are used: depth of anesthesia, circulation, respiration, body temperature, and muscle relaxation depth. In this embodiment, five major categories are used, but this is not limited to them. There may be two to four major categories, or six or more. Furthermore, examples of subcategories (items) included in each major category include, for depth of anesthesia, BIS (Bispectral Index), PSI (Patient State Index), SR (Suppression Ratio), SEF (Spectral Edge Frequency) left / right, and EMG (ElectroMyography). For circulation, HR (Heart Rate), ART (M), and NIP (Non-invasive Blood Pressure) are examples. For respiration, EtCO2 (End-tidal CO2) and SpO2 (Saturation of percutaneous O2) are examples. For body temperature, T1 value and T2 value are examples. Furthermore, examples of muscle relaxation depth include TOF (Train-Of-Four) and T1%.

[0025] The duration derivation unit 42 derives the duration for each type of biological information. For example, if the category is anesthetic depth, it derives the duration for each of BIS, PSI, SR, SEF left / right, and EMG.

[0026] As a specific example, we will describe a method of deriving the duration using the duration derivation unit 42 when the type of biological information is BIS.

[0027] When the type of biological information is BIS, the duration derivation unit 42 derives the duration during which the BIS value continues to be abnormal, that is, within a range deviating from the normal range, for a predetermined time or more. As a specific example, in the present embodiment, the BIS value is classified into four stages: normal, small deviation degree, medium deviation degree, and large deviation degree according to the degree of deviation from the normal range, and the duration derivation unit 42 derives the duration for each of the three stages of small deviation degree, medium deviation degree, and large deviation degree. In the present embodiment, the case where it is classified into four stages according to the degree of deviation from the normal range has been described, but the classification method and the like are not limited to this aspect. For example, it may be classified into two stages, three stages, or five or more stages.

[0028] The numerical range for a small deviation degree is that the BIS value is 35 or more and less than 40 (35 ≤ BIS < 40), or exceeds 60 and is 65 or less (60 < BIS ≤ 65), and the predetermined time is 3 minutes. The numerical range for a medium deviation degree is that the BIS value is 30 or more and less than 35 (30 ≤ BIS < 35), or exceeds 65 and is 70 or less (65 < BIS ≤ 70), and the predetermined time is 3 minutes. The numerical range for a large deviation degree is that the BIS value is less than 30 (BIS < 30), or exceeds 70 (70 < BIS), and the predetermined time is 3 minutes. In the present embodiment, the duration for each classification according to the degree of deviation from the normal range is the same, but it may be a different value for each classification according to the degree of deviation from the normal range.

[0029] As an example, the duration derivation unit 42 derives, as the duration for a small deviation degree, the time that does not overlap with the time during which the BIS value is less than 35 and continues for 3 minutes or more within the period during which the time when the BIS value is less than 40 continues for 3 minutes or more. Also, the time that does not overlap with the time during which the BIS value exceeds 65 and continues for 3 minutes or more within the period during which the time when the BIS value exceeds 60 continues for 3 minutes or more is derived. Hereinafter, the duration for a small deviation degree is referred to as T1.

[0030] In other words, in this embodiment, if the BIS value is less than 40 for a period of 3 minutes or more, and the BIS value is less than 35 for a period of less than 3 minutes, it can be considered that the value has deviated from the low deviation range due to noise, for example. Therefore, it is considered to be included in the low deviation period. Similarly, if the BIS value is greater than 65 for a period of 3 minutes or more, and the BIS value is greater than 60 for a period of less than 3 minutes, it can be considered that the value has deviated from the low deviation range due to noise, for example. Therefore, it is considered to be included in the low deviation period.

[0031] Furthermore, the duration derivation unit 42 derives a duration within the deviation that is 3 minutes or more during which the BIS value is less than 35, and does not overlap with a duration that is 3 minutes or more during which the BIS value is less than 30. It also derives a duration that is 3 minutes or more during which the BIS value is greater than 65, and does not overlap with a duration that is 3 minutes or more during which the BIS value is greater than 70. Hereinafter, the duration within the deviation will be referred to as T2.

[0032] In other words, in this embodiment, if the BIS value is less than 35 for a period of 3 minutes or more, and the BIS value is less than 30 for a period of less than 3 minutes, it can be considered that the value has deviated from the numerical range within the deviation degree due to noise, for example. Therefore, it is considered to be included in the period within the deviation degree. Also, if the IS value is greater than 70 for a period of 3 minutes or more, and the BIS value is greater than 65 for a period of less than 3 minutes, it can be considered that the value has deviated from the numerical range with a small deviation degree due to noise, for example. Therefore, it is considered to be included in the period within the deviation degree.

[0033] Furthermore, the duration derivation unit 42 derives the duration for which the BIS value is less than 30 for 3 minutes or more as the duration of a large deviation. It also derives the duration for which the BIS value exceeds 70 for 3 minutes or more. Hereinafter, the duration of a large deviation will be referred to as T3.

[0034] Referring to Figure 3, a specific example of how the duration derivation unit 42 derives an evaluation index for BIS will be explained. In the example shown in Figure 3, the duration derivation unit 42 identifies the following periods in which the BIS value is less than 40: period s1 with a duration of 3 minutes, period s2 with a duration of 3 minutes, period s3 with a duration of 2 minutes, period s4 with a duration of 2 minutes, period s5 with a duration of 1 minute, period s6 with a duration of 1 minute, and period s7 with a duration of 8 minutes. Of periods s1 to s7, the periods that are 3 minutes or longer are periods s1, s2, and s7. Therefore, the duration derivation unit 42 derives a duration T1 for each of periods s1, s2, and s7. For period s1, the duration T1 is 3 minutes because the time in period s1 in which the BIS value is less than 35 is 1 minute (see period m1). In period s2, the duration T1 is 3 minutes because the time during period s2 when the BIS value is less than 35 is 0 minutes. In period s7, the duration T1 is 8-3=5 minutes because the time during period s7 when the BIS value is less than 35 is 1 minute (see period m2) and 3 minutes (see period m3). Thus, the duration derivation unit 42 derives 3 minutes, 3 minutes, and 5 minutes as durations T1 with small deviations in the BIS value.

[0035] On the other hand, in the example shown in Figure 3, the duration derivation unit 42 identifies three periods where the BIS value is less than 35: period m1 with a duration of 1 minute, period m2 with a duration of 1 minute, and period m3 with a duration of 3 minutes. Of periods m1 to m3, the period that is 3 minutes or longer is period m3. Therefore, the duration derivation unit 42 derives the duration T2 for period m3. In period m3, the duration T2 is 3 minutes because the time during which the BIS value is less than 30 is 0 minutes. Thus, the duration derivation unit 42 derives 3 minutes as the duration T2 within the BIS value deviation.

[0036] On the other hand, in the example shown in Figure 3, the duration derivation unit 42 derives 0 minutes as the duration T3 with a large deviation in the BIS value, because there is no period in which the BIS value is less than 30.

[0037] The duration derivation unit 42 outputs the derived duration to the evaluation index derivation unit 44.

[0038] The evaluation index derivation unit 44 derives evaluation indices for biological information values ​​based at least on the duration and the duration of surgery.

[0039] As an example, the case where the type of biological information is BIS will be explained in detail. As an example, assuming a maximum score of 100 points, the evaluation index derivation unit 44 derives an evaluation index for the BIS value using a point deduction method. If the degree of deviation is small, 20 points × (total value of the duration T1 for small deviations ÷ surgical period) are deducted. If the degree of deviation is medium, 50 points × (total value of the duration T2 for medium deviations ÷ surgical period) are deducted. If the degree of deviation is large, 100 points × (total value of the duration T3 for large deviations ÷ surgical period) are deducted. Note that the number of points deducted and the duration for each degree of deviation are not limited to the values ​​in this embodiment. At least one of the number of points deducted or the duration may differ for each type of biological information. Also, at least one of the number of points deducted or the duration may be a predetermined set value or a value that the user can arbitrarily specify. Furthermore, at least one of the deduction points or duration may be adjusted so that the evaluation index for the medical procedure information group consisting of multiple medical procedure information 32 has a specific distribution. For example, at least one of the deduction points or duration may be adjusted so that the evaluation index is 80% or higher for 80% of the medical procedure information group.

[0040] In other words, the evaluation index derivation unit 44 derives the evaluation index using the following equation (1).

[0041] Evaluation index = 100 - 20 × (Total T1 value ÷ Surgery period) - 50 × (Total T2 value ÷ Surgery period) - 100 × (Total T3 value ÷ Surgery period) ... (1)

[0042] As described above, a specific example of how the evaluation index derivation unit 44 derives an evaluation index when the BIS value is as shown in Figure 3 will be explained. The surgical period is assumed to be 60 minutes. In the example of the BIS value shown in Figure 3, the duration T1 for which the BIS value deviation is small is s1 is 3 minutes, s2 is 3 minutes, and s7 is 5 minutes, so the total value of T1 is 11 minutes. The duration T2 for which the BIS value deviation is medium is 3 minutes for s3, so the total value of T2 is 3 minutes. The duration T3 for which the BIS value deviation is large is 0 minutes, so the total value of T3 is 0 minutes. From equation (1) above, as shown in equation (2) below, the evaluation index derivation unit 44 derives "93.8 points" as the evaluation index. The evaluation index derived in this way may be referred to as the "score" below.

[0043] Evaluation score = 100 - 20 × (11 ÷ 60) - 50 × (3 ÷ 60) - 100 × (0 / 60) = 93.8 points The evaluation index derivation unit 44 outputs the derived evaluation index to the display control unit 46.

[0044] The display control unit 46 controls the display of the evaluation index on the display unit 28. In this embodiment, since there are multiple types of biological information, the display control unit 46 controls the display of the evaluation index for each type. The display control unit 46 may also control the display of the evaluation values, which are the evaluation indexes, by relatively emphasizing them based on their relative magnitude. Specifically, the display control unit 46 may emphasize and display evaluation values ​​that are of a higher degree than low values ​​so that they stand out more. For example, if an evaluation index is higher than a predetermined reference value, it may be displayed with relative emphasis compared to cases where it is below the reference value. Relative emphasis can be achieved, for example, by making the thickness, color, background color, etc., of the notation for the major category of biological information or the notation for the evaluation index relatively different. The reference value may be a different numerical value for each type of biological information. The reference value may be a predetermined set value or a value that can be entered by the user. The reference value may also be set based on the statistical values ​​of the evaluation index for each major category of biological information in a medical treatment information group consisting of multiple medical treatment information 32. For example, a baseline value such as 80% of the average or maximum value, which are statistical values, may be used. Furthermore, the medical procedure information group may consist of medical procedure information 32 within the same medical facility, or multiple medical procedure information 32 associated with the same clinical department, surgical procedure, organ, or disease. For example, if there are evaluation indicators such as the top 20% or top 10 cases in the circulatory evaluation indicators of multiple medical facility information 32 associated with the same medical facility, these may be displayed with relative emphasis compared to other cases.

[0045] Furthermore, the display control unit 46 controls the display of a warning based on the duration. Specifically, it controls the display of a warning if the duration is longer than a predetermined time. The predetermined time, which serves as an indicator for determining whether or not to display a warning, may be set for each type of biological information, for example, each item of biological information in this embodiment, or it may be set for each item in multiple stages, in which case the time may be different for each stage. The warning displayed by the display control unit 46 may be a visible display on the display unit 28, or an audible display.

[0046] Furthermore, the display control unit 46 of this embodiment may also perform control to further display, as detailed display, information on drug administration to the patient associated with the type of biological information, and information on the drug's concentration in the body. For example, the display control unit 46 may also perform control to further display information on drug administration that affects biological information, and information on the drug's concentration in the body. For example, in the case of BIS, the display control unit 46 may further display information on anesthetic drug administration and information on the anesthetic drug's concentration in the body.

[0047] Next, the operation of the information processing device 10 of this embodiment will be described with reference to the drawings. Figure 4 shows a flowchart illustrating an example of the flow of information processing performed in the information processing device 10 of this embodiment. In this embodiment, as an example, the information processing device 10 executes the information processing shown as an example in Figure 4 by having the CPU 20A of the control unit 20 execute the information processing program 30 stored in the storage 22C based on a user's start instruction made by the operation unit 26.

[0048] In step S100 of Figure 4, the acquisition unit 40 acquires medical treatment information 32 from the storage 22C of the memory unit 22, as described above.

[0049] In the next step S102, the duration derivation unit 42 derives the duration as described above. If the medical procedure information 32 includes multiple types of biological information, the duration derivation unit 42 derives the duration for each type. In this embodiment, as described above, the duration is derived for each item in each category. Also, as described above, the duration may be derived for each item in multiple stages. For example, in the case of the BIS value example above, the duration T1 for small deviation, the duration T2 for medium deviation, and the duration T3 for large deviation are derived, respectively.

[0050] In the next step S104, the evaluation index derivation unit 44 derives an evaluation index based on the duration derived in step S102, as described above. If the medical treatment information 32 includes multiple types of biological information, the duration derivation unit 42 derives an evaluation index for each type. In this embodiment, as described above, an evaluation index is derived for each item in each category. For example, in the case of the BIS value example above, the evaluation index (score) is derived using equation (1) above.

[0051] In the next step, S106, the display control unit 46 displays the evaluation index derived in step S104 on the display unit 28, as described above. When the processing in step S106 is completed, the information processing shown in Figure 4 is completed.

[0052] Figures 5A to 5C show examples of how the display control unit 46 displays evaluation indicators on the display unit 28. Figure 5A is an example of a first display format in which multiple evaluation indicators derived for each type of biological information are arranged in a matrix. Figure 5B is an example of a second display format in which multiple evaluation indicators derived for each type of biological information (major category) of "circulation," "respiration," "body temperature," "depth of anesthesia," and "depth of muscle relaxation" are arranged vertically. Figure 5C is an example of a third display format in which details of the evaluation indicator and multiple evaluation indicators derived for each type of biological information arranged vertically are displayed for each biological information. Alternatively, a display format that shows details of the evaluation indicator for each biological information may be applied instead of the third display format, or in addition to the third display format.

[0053] Figures 5A to 5C show the case where there are five types (major categories) of biological information, but the number of types (major categories) of biological information to be displayed is not limited to five; it may be four or fewer, or six or more. As an example, Figures 6A to 6C show the case where there are six types (major categories) of biological information. In Figures 6A to 6C, in addition to the five major categories mentioned above, the item "Balance" is added. In the Balance section, "IN" represents the amount of intravenous fluids and transfused blood, and "OUT" represents the amount of urine and blood loss, making it possible to recognize the final value and trend of the balance between the amount of blood and water in the body.

[0054] As shown in Figures 5A to 6C, each category has a rectangular frame containing details of the main and sub-categories. The main category name is written in an L-shaped block that includes the top edge of the frame and the edge that intersects with the top edge. As shown in Figure 6D, the L-shaped blocks corresponding to each main category may be displayed in different ways. For example, they may have different background colors or text colors.

[0055] Furthermore, in the examples shown in Figures 5A to 6C, the details of each sub-item are displayed in the following order: chart (graph showing fluctuations), warning display (see "!" in the figure), and statistical information. The graph showing fluctuations is, for example, a graph showing the vital signs for each sub-item over time during the surgical period. Note that multiple sub-items may be grouped together and displayed as a single graph in the chart. For example, in the case of "circulation," the graphs for HR, ART, and NBP may be displayed superimposed, or their respective normal ranges may be displayed together.

[0056] Furthermore, in the example of the third display format shown in Figures 5C and 6C, a detailed display is shown that further displays biological information, drug administration information to the patient associated with the type of biological information, and drug concentration information in the body. In the embodiments shown in Figures 5C and 6C, instead of the details of BIS, details of multiple items such as BIS and PSI may be displayed as a single graph, that is, the respective graphs may be superimposed.

[0057] Furthermore, as shown in Figure 6E, in the third display format, biological information and detailed information on the administration of related drugs (administration records) may be displayed side by side. In the example shown in Figure 6E, as biological information for "circulation," graphs for the items with checkboxes checked, "NIP," "ART," and "HR," are displayed superimposed. In this way, it may be possible to switch (select) which items the graphs are displayed for. Also, in the example shown in Figure 6E, detailed information on the administration of multiple types of drugs can be displayed as administration records. For example, as shown in the upper section, a graph showing the hourly dosage of three types of drugs, "neosynezin," "ephedrine," and "norepinephrine," during surgery may be displayed. Alternatively, as shown in the lower section, the timing of each administration may be displayed individually. In addition, detailed information may be displayed for drugs with checkboxes checked.

[0058] Furthermore, in the third display format, as shown in Figure 6E, a surgical events column may be provided to display details of surgical events. For example, surgical events such as intubation or major changes related to the patient's vital signs may be displayed in association with the time at which the event occurred. Also, as shown at the top of Figure 6E, the item names, statistical values, and surgical duration of subcategories included in the major categories may be displayed. In this case, as with the first and second display formats, evaluation indicators may also be displayed, or they may be highlighted according to their evaluation indicators.

[0059] Regarding the display of vital signs, in addition to drug administration information, particularly anesthetic drug administration information, or in place of drug administration information, respiratory management records may be displayed. Alternatively, only detailed vital signs (graphs) may be displayed without displaying administration information or other data.

[0060] The first to third display formats are not particularly limited and may be set according to user specification, and it may be possible to switch between the first to third display formats. For example, the first and second display formats may be switched based on the aspect ratio of the display screen of the display unit 28. Specifically, the display control unit 46 may set the first display format if the display unit 28 is horizontally oriented, and the second display format if the display unit 28 is vertically oriented, based on the aspect ratio. The display screen of the display unit 28 may be the entire display area where the display elements of the display unit 28 are arranged, or it may be a part of the display area, such as a window that displays evaluation indicators in the first or second display format. In addition, the display may be switched to the third display format if any of the multiple evaluation indicators displayed in the first or second display format are specified by the user, or if any button is specified by the user.

[0061] As described above, the information processing device 10 of this embodiment comprises an acquisition unit 40, a duration derivation unit 42, and an evaluation index derivation unit 44. The acquisition unit 40 acquires biological information values ​​representing biological information about a living organism during a treatment period related to medical treatment on a living organism. The duration derivation unit 42 derives the duration for which the biological information value remains within a numerical range associated with the type of biological information for a predetermined period of time or longer. The evaluation index derivation unit 44 outputs an evaluation index derived based on at least the duration and the treatment period.

[0062] Therefore, the information processing device 10 of this embodiment can exclude cases where biological information values ​​suddenly fall within the numerical range, such as noise, and thus can perform evaluations with higher accuracy compared to cases that are not based on duration.

[0063] The evaluation index may be a statistical value of the biological information value or a standard deviation of the evaluation value of the biological information value. For example, it may be a statistical value or standard deviation for each item, or a statistical value or standard deviation for each category. That is, for each category, it may be a statistical value or standard deviation of evaluation indexes for multiple items. The information processing device 10 may display a list of multiple medical procedure information 32 together with the evaluation index. The information processing device 10 accepts input of conditions for the medical procedure information 32 to be displayed in a list, for example, via the operation unit 26. The conditions for the medical procedure information 32 to be displayed in a list are, for example, conditions that specify at least one of the patient's age, sex, medical department, surgical procedure, disease, organ, and date of surgery, which are recorded in association with the medical procedure information 32. Based on the input conditions, the information processing device 10 extracts the corresponding multiple medical procedure information 32 and displays them together with the evaluation index. Figure 7 shows an example of an evaluation index. The list shown in Figure 7 is a list of cases including the standard deviation, which is the evaluation index for each case, and this list of cases is displayed, for example, as information indicating the patient's condition during surgery. In the example shown in Figure 7, for each case, information about the surgery and evaluation indicators are displayed, including the standard scores for circulation, respiration, body temperature, depth of anesthesia, depth of muscle relaxation, and the overall average standard score. Note that the evaluation indicators displayed are not limited to standard scores, and the statistical values ​​of the evaluation indicators may be displayed instead of the evaluation indicators themselves. For example, in the example in Figure 7, the standard scores of the evaluation indicators for each major category and the average of the standard scores of all major category evaluation indicators are displayed as the overall statistical value for the major categories, but this is not limited to this. Instead of the standard scores of the evaluation indicators for each major category, or in addition to them, the evaluation indicators for each major category may be displayed. Instead of the average of the standard scores of all major category evaluation indicators, or in addition to them, at least the maximum or minimum value of the standard scores of all major category evaluation indicators may be displayed as the overall statistical value for the major categories. Note that only the evaluation indicators for each major category or only the overall statistical value for the major categories may be displayed.Furthermore, when displaying a list of multiple medical procedure information 32, the system may sort and display the specified evaluation indicators in either descending or descending order, depending on the initial display or user input. The display control unit 46 may also perform control in Figure 7 to highlight and display items with lower evaluation values ​​that are of a higher degree. For example, if an evaluation indicator is higher than a predetermined standard value, it may be displayed with relative emphasis compared to cases where it is below the standard value.

[0064] In the above, scores, i.e., numerical values, are derived as evaluation indicators, but it is also possible to derive degrees such as "high," "medium," and "low," or "good" and "bad." Specifically, a reference range for the evaluation indicator may be set for each piece of information indicating degree, and degree information indicating that reference range may be presented. The reference range may be an absolute reference range, such as 60% or more and less than 80% for the evaluation indicator, or it may be a relative reference range, such as the top 20% or top 10, among the evaluation indicators shown by a group of medical treatment information for each facility.

[0065] Furthermore, while the above method derives evaluation indices for biological information values, evaluation indices related to the patient's condition derived from biological information values ​​may also be derived. For example, the evaluation index (score) derived by equation (1) above evaluates the BIS value itself. Alternatively, in the case of this score, for example, in the specific example above, if the score is 93.8 points, an evaluation index could be derived that indicates what the patient's condition was during the surgical period, for example, whether it was "good".

[0066] Furthermore, for example, if the medical procedure information 32 includes administration information, the acquisition unit 40 may acquire administration information regarding the administration of a drug to the patient from the medical procedure information 32, and based on the administration information, acquire the type of biological information and the biological information value if the drug administration satisfies predetermined administration conditions. For example, TOF and T1(%), which are items of muscle relaxation depth, may be acquired when at least one of the following conditions is met: the muscle relaxant has been administered multiple times in single shots, and the total amount administered is 0.6 mg or more per kg of body weight, or the muscle relaxant has been continuously administered.

[0067] Furthermore, in the above embodiment, the living organism described was a patient, i.e., a human body, but it could also be, for example, a sick animal, i.e., a human animal. Also, although this embodiment is limited to medical-related applications, it could be unrelated to medical applications, and the evaluation index could be derived based on subject information regarding the subject during the observation period.

[0068] Furthermore, while the above embodiment described the case where the numerical range is abnormal, the evaluation index may also be derived based on the normal range. For example, the normal range may be defined as a BIS value between 40 and 60, and the duration may be derived to derive the evaluation index. Alternatively, as with the deviation degree described above, the normal range may be divided into steps, and the duration may be derived for each step to derive the evaluation index.

[0069] It goes without saying that the configuration and operation of the information processing device 10, etc., described in the above embodiments are merely examples and can be modified as needed without departing from the spirit of the present invention. It also goes without saying that the above embodiments may be combined as appropriate.

[0070] Furthermore, in this embodiment, each process is executed on any computer. Alternatively, any computer may execute these processes using a processor as hardware, a program as software, or a combination thereof. In that case, the processor is configured to work in cooperation with the program to execute the various processes in this embodiment, and can function as a unit or means in this embodiment. The execution order of the processes by the processor is not limited to the order described and may be changed as appropriate. Any computer may be a general-purpose computer, a computer designed for a specific application, a workstation, or any other system capable of executing each process. For example, the information processing device 10 has a display unit 28, and the display control unit 46 controls the display of evaluation indicators on the display unit 28. However, the display unit 28 may be an external device, and the display control unit 46 may control the display of evaluation indicators on the display unit 28 of the external device connected via communication.

[0071] A processor may consist of one or more hardware components, and the type of hardware is not limited. For example, a processor may consist of a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a programmable logic device such as an FPGA (Field Programmable Gate Array), a dedicated circuit for executing a specific process such as an ASIC (Application Specific Integrated Circuit), a GPU (Graphic Processing Unit), or an NPU (Neural Processing Unit). Furthermore, the type of hardware may be a combination of different types of hardware. When multiple hardware components are configured to execute one or more processes of a processor, these components may reside in physically separate devices or in the same device. Also, in any embodiment, the order of each process performed by the processor is not limited to the order described above and may be changed as appropriate. Hardware is composed of electrical circuits (circuitry) that combine circuit elements such as semiconductor elements.

[0072] Furthermore, the program may be firmware or software such as microcode. Alternatively, the program may be, for example, a set of program modules, each function of which may be implemented by a processor configured to perform its respective function. The program may be program code or multiple code segments stored on one or more non-temporary computer-readable media (e.g., storage media or other storage). The program may be divided and stored on multiple non-temporary computer-readable media located on physically separate devices. Program code or code segments may represent any combination of procedures, functions, subprograms, routines, subroutines, modules, software packages, classes, or instructions, data structures, or program statements. Program code or code segments may be connected to other code segments or hardware circuits by sending and receiving information, data, arguments, parameters, or memory contents.

[0073] Furthermore, although the above embodiment describes an embodiment in which the information processing program 30 is pre-stored (installed) in the storage 22C of the memory unit 22, the invention is not limited to this. The information processing program 30 may be provided in the form of a recording medium such as a CD-ROM (Compact Disc Read Only Memory), DVD-ROM (Digital Versatile Disc Read Only Memory), or USB (Universal Serial Bus) memory.
