Description

The present invention relates to a condition change display device.

Conventionally, when the condition of a patient in a hospital suddenly changes, for example, when the heart rate drops below a certain value, an alarm sensor is activated to notify the medical staff.

However, the method of notifying the medical staff of the change in the patient's condition by the alarm sensor cannot prevent the illness because the medical staff is notified at the stage when the illness has already developed. From the viewpoint of disease prevention, it is desirable to be able to detect the disease at the stage of a sign of sudden change in the condition. As a method for capturing such a change in the patient's condition, for example, NEWS (National Early Warning Score), EWS (Early Warning Score), SOFA (Sequential Organ Failure Assistance), qSOFA (quic2) method, qSOFA (quic) method, etc. Is known (see Patent Document 1).

FIG. 2 is a diagram showing a reference value of NEWS, which is one of the discrimination methods. NEWS is a method for determining sepsis. As shown in FIG. 2, the endpoints (parameters) used in NEWS are respiratory rate, percutaneous arterial oxygen saturation (SpO ₂ ), oxygen support, body temperature, systolic blood pressure, heart rate, and consciousness level. When the determination of sepsis is performed using NEWS, for example, when the respiratory rate per minute acquired by the acquisition unit 4 is 8 or less or 25 or more, the score regarding the respiratory rate is 3. If the respiratory rate is 21 or more and 24 or less, the respiratory rate score is 2. When the respiratory rate is 9 or more and 11 or less, the score for the respiratory rate is 1. When the respiratory rate is 12 or more and 20 or less, the score for the respiratory rate is 0. For the remaining parameters, the score is calculated based on the standard values and the like defined in the medical guidelines and the like. The calculated scores are added up. In the present specification, this total score is referred to as a total score A.

FIG. 3 is a diagram showing a reference value of SOFA, which is one of the discrimination methods. SOFA is a method for determining sepsis. SOFA is particularly used in determining whether or not there is an organ disorder. The endpoints (parameters) used in SOFA are consciousness, respiration, circulation, plasma bilirubin level, plasma creatinine level, and coagulated platelet count. For example, when the number of coagulated platelets acquired by the acquisition unit 4 is less than 20, the score for the number of coagulated platelets is 4. When the number of coagulated platelets is 20 or more and less than 50, the score for the number of coagulated platelets is 3. When the number of coagulated platelets is 50 or more and less than 100, the score for the number of coagulated platelets is 2. When the number of coagulated platelets is 100 or more and less than 150, the score for the number of coagulated platelets is 1. When the number of coagulated platelets is 150 or more, the score regarding the number of coagulated platelets is 0. For the remaining items, the score is calculated based on the standard values set in the medical guidelines. The calculated scores are added up. In the present specification, this total score is referred to as a total score B.

FIG. 4 is a diagram showing a reference value of qSOFA, which is one of the discrimination methods. qSOFA is a method for determining sepsis. qSOFA is used specifically in determining whether or not an infectious disease is present. As shown in FIG. 4, the evaluation items (parameters) used in qSOFA are respiratory rate, systolic blood pressure, and consciousness. For example, when the respiratory rate acquired by the acquisition unit 4 is 22 times or more per minute, the score regarding the respiratory rate is 1. If this is not the case, the score is 0. Further, when the collection period blood pressure acquired by the acquisition unit 4 is 100 mmHg or less, the score regarding the systolic blood pressure is 1. If this is not the case, the score is 0. In addition, if the patient is unconscious, the consciousness score is 1. On the other hand, if the patient is conscious, the consciousness score is 0. The calculated scores are added up. In the present specification, this total score is referred to as a total score C.

5A and 5B are diagrams showing a reference value of APACHE2, which is one of the discrimination methods. APACHE2 is a method for determining the severity of a patient. As shown in FIG. 5A, the endpoints (parameters) used in APACHE2 are body temperature, mean blood pressure, heart rate, respiratory rate, oxygenation, arterial blood PH, serum Na, serum K, plasma Cre, hematocrit (Ht), leukocytes. Number (WBC), Glasgow Coma Scale (GCS). For example, when the mean blood pressure acquired by the acquisition unit 4 is 160 or more or 49 or less, the score regarding the mean blood pressure is 4. When the mean blood pressure is 130 or more and 159 or less, the score regarding the mean blood pressure is 3. When the mean blood pressure is 110 or more and 129 or less, or 50 or more and 69 or less, the score for mean blood pressure is 2. When the mean blood pressure is 70 or more and 109 or less, the score regarding the mean blood pressure is 0. For the remaining items, the score is calculated based on the standard values set in the medical guidelines. The calculated scores are added up. In the present specification, this total value is referred to as a total value X.

As shown in FIG. 5B, when APACHE2 is used, age points and chronic pathological condition points are added to the total value X. For example, when the patient is 45 years old and is a patient after emergency surgery, 2 points as age points and 5 points as chronic pathological condition points are added to the total value X, respectively. As used herein, this value is referred to as the Apache score. The discrimination unit 6 calculates the severity mortality rate by performing a predetermined calculation based on the Apache score.

In the present specification, it is based on the biological information acquired by the acquisition unit 4 and each discrimination method stored in the storage unit 5, such as the total score A, the total score B, the total score C, and the severity mortality rate. The value, percentage, etc. calculated by the discriminating unit 6 is called a total score.

As described above, for example, even in the method for discriminating sepsis, the medical meaning of the reference value and the value of the total score is different for each discriminating method.

FIG. 6 is a diagram showing a standardized table P in each discrimination method. The standardized table P is a table for classifying and displaying the patient's condition level into four color groups for each discrimination method. The four color groups in this embodiment are a white group, a green group, an orange group, and a red group. The white group corresponds to the condition level that the patient is in a normal state. The red group corresponds to the condition level at which the patient is in an abnormal and dangerous condition. The orange group corresponds to the condition level that the patient is not normal, though not as much as the patient in the red group. The green group corresponds to the condition level that the patient is not normal, though not as much as the patient in the orange group. That is, the condition levels of patients other than the white group are worse in the order of the green group, the orange group, and the red group. The classification of the color groups shown here is only an example. Of course, the classification of color groups is not limited to this example.

For example, for NEWS, when the overall score A is 0, the color group is classified into the white group. When the total score A is 1 or more and 4 or less, the color group is classified into the green group. When the overall score A is 5 or more and 6 or less, or at least one of the evaluation items in NEWS is a score of 3, the color group is classified into the orange group. When the overall score A is 7 or more, the color group is classified into the red group.

For SOFA, when the overall score B is 0, the color group is classified into the white group. When the total score B is 1, the color group is classified into the orange group. When the total score B is 2 or more, the color group is classified into the red group.

For qSOFA, when the overall score C is 0, the color group is classified into the white group. When the total score C is 1, the color group is classified into the orange group. When the total score C is 2 or more, the color group is classified into the red group.

For APACHE2, the color group is classified as the white group when the severe mortality rate is 0%. When the severity mortality rate is greater than 1% but less than 50%, the color group is classified as a green group. When the severity mortality rate is greater than 50% but less than 75%, the color group is classified as an orange group. When the severity mortality rate is greater than 75%, the color group is classified as a red group.

FIG. 7 is a diagram showing a standardization table Q for standardizing the parameters constituting each discrimination method. As shown in FIG. 7, for example, when the respiratory rate per minute is 12 or more and 20 or less, the color group is classified into the white group. When the respiratory rate is 9 or more and 11 or less, the color group is classified into the green group. When the respiratory rate is 21 or more and 24 or less, the color group is classified into the orange group. When the respiratory rate is 8 or less or 25 or more, the color group is classified as a red group.

As shown in FIG. 7, for oxygen supplementation, the color group is classified into an orange group when oxygen supplementation is required, and a white group when oxygen supplementation is not required. Regarding the urine volume, when the daily urine volume is 500 mL or more, the color group is classified into the white group. When the daily urine volume is 200 mL or more and less than 500 mL, the color group is classified into the orange group. When the daily urine volume is less than 200 mL, the color group is classified as a red group. The other parameters are classified into four stages, and one color group is associated with each stage.

Returning to FIG. 1, the configuration of the condition change display device 1 will be described. The discrimination unit 6 is configured to discriminate changes in the patient's condition based on the biological information acquired by the acquisition unit 4 and the discrimination method stored in the storage unit 5. For example, when NEWS and SOFA are used to determine whether a patient has septic disease, the discriminating unit 6 includes biometric information acquired by the acquisition unit 4 and NEWS stored in the storage unit 5. The total score A and the total score B are calculated based on the reference value of SOFA. The discrimination unit 6 determines and classifies which of the above-mentioned four color groups the total score A and the total score B correspond to, based on the standardized table P stored in the storage unit 5.

In addition, the discriminating unit 6 can also discriminate whether the measured value or the total score at a certain point in time is rising or falling compared to the immediately preceding measured value or the total score, or whether or not it has changed (trend). Is. The discrimination unit 6 generates a trend information signal based on the discrimination result. The signal is transmitted to the control unit 2.

The display unit 7 is a display such as a liquid crystal display or an organic EL display, and is configured to display the discrimination result by the discrimination unit 6.

The display control unit 8 controls the display unit 7 to display the discrimination result by the discrimination unit 6 in a display mode standardized based on the standardized table P or the standardized table Q stored in the storage unit 5. It is possible. The standardization method in this embodiment is a method of coloring a predetermined portion.

Based on the trend information signal received from the discriminating unit 6, the display control unit 8 increases or decreases the measured value or the total score at a certain time point with respect to the display unit 7 as compared with the immediately preceding measured value or the total score. Controls to display a symbol indicating whether or not it has changed.

The display control unit 8 may control the display unit 7 to color the symbol based on the color group determined by the discrimination unit 6.

FIG. 8 is a diagram relating to a screen for displaying changes in the patient's condition. As shown in FIG. 8, the display unit 7 displays the change in the patient's condition in a standardized, that is, colored display mode. In the embodiments shown in FIGS. 8 to 10, hatching is added instead of the color. The hatch corresponding to the white group is plain. The hatch corresponding to the green group is a diagonal line that slopes from the upper left to the lower right. The hatches corresponding to the orange group are horizontal lines. The hatches corresponding to the red groups are vertical lines. The screen shown in FIG. 8 is divided into four sections. Information about each patient is displayed in each compartment. In the screen example shown in FIG. 8, changes in the condition of the four patients can be confirmed in a list.

The patient name is displayed in the upper center of each section. On the left side of the patient name, the identification number corresponding to the patient is displayed. The room number corresponding to the patient is displayed on the left side of the identification number. In this specification, information including a patient name, an identification number, and a room number may be referred to as patient identification information. Room numbers are colored according to the color groups classified based on the overall score or numerical value as of the latest time point (10:00, July 10, 2017). Below the room number, the name of each discrimination method or parameter arbitrarily selected by the medical staff is displayed. On the right side of each discrimination method name or parameter name, the discrimination result corresponding to each discrimination method or parameter is displayed. The discrimination results are displayed in chronological order. The determination result is displayed as a vertical bar graph or a horizontal bar graph. The discrimination result is standardized, that is, colored based on the total score or the measured value corresponding to the discrimination method or the parameter. Therefore, the discrimination results are visually distinguished.

Focusing on Kotaro, the screen shown in FIG. 8 will be described in detail. Information about Kotaro is displayed in the upper left section. Information on NEWS, SOFA, and Lactate is displayed in a horizontal bar graph in the section. Focus on the horizontal bar graph for NEWS. For example, when the total score of Kotaro's NEWS from 4:00 on July 10, 2017 to 5:40 on the same day is 0, the discriminating unit 6 sets the total score of Kotaro's NEWS in the time zone to white. Classify into groups. Therefore, the horizontal bar graph in the time zone is colored in white. When the total score of Kotaro's NEWS from 5:40 to 7:20 on the same day is 1 to 4, the discriminating unit 6 classifies the total score of Kotaro's NEWS in the time zone into the green group. Therefore, the horizontal bar graph in the time zone is colored in green. When the total score of Kotaro's NEWS after 7:20 on the same day is 5 to 6, the discriminating unit 6 classifies the total score of Kotaro's NEWS in the time zone into the orange group. Therefore, the horizontal bar graph in the time zone is colored orange.

Focus on the horizontal bar graph for SOFA. For example, when the total SOFA score of Kotaro from 4:00 on July 10, 2017 to 6:40 on the same day is 0, the discriminating unit 6 sets the total SOFA score of Kotaro in the time zone to white. Classify into groups. When the total score of Kotaro's SOFA after 6:40 on the same day is 1, the discriminating unit 6 classifies the total score of Kotaro's NEWS in the time zone into the orange group.

Focus on the horizontal bar graph for lactate. For example, when the value of photoelectric Taro's lactate from 4:00 on July 10, 2017 to 4:40 on the same day is less than 1 mmol / l, the discriminating unit 6 sets the value of photoelectric Taro's lactate in the time zone. Classify into white group. When the value of Photoelectric Taro's lactate from 4:40 to 7:00 on the same day is 1 mmol / l, the discriminating unit 6 classifies the value of Photoelectric Taro's lactate in the time zone into the green group. When the value of Photoelectric Taro's lactate after 7:00 on the same day is 2 mmol / l to 4 mmol / l, the discriminating unit 6 classifies the value of Photoelectric Taro's lactate in the time zone into an orange group.

Next, focusing on Kozaburo, the screen shown in FIG. 8 will be described in detail. Information about Kozaburo is displayed in the lower left section. Information about NEWS is displayed in the section as a vertical bar graph and a horizontal bar graph. The horizontal bar graph is located above the vertical bar graph. As shown in the vertical bar graph, the total score of Kozaburo's NEWS from 4:00 on July 10, 2017 to 5:20 on the same day has changed from 1 to 4. Therefore, the discrimination unit 6 classifies the total score of Kozaburo's NEWS in the time zone into the green group. Therefore, the vertical bar graph and the horizontal bar graph in the time zone are colored in green. From 5:20 to 8:40 on the same day, Kozaburo's NEWS overall score has changed from 5 to 6. Therefore, the discrimination unit 6 classifies the total score of Kozaburo's NEWS in the time zone into the orange group. Therefore, the vertical bar graph and the horizontal bar graph in the time zone are colored in orange. From 8:40 to 9:00 on the same day, Kozaburo's NEWS overall score is 7. Therefore, the discrimination unit 6 classifies the total score of Kozaburo's NEWS in the time zone into the red group. Therefore, the vertical bar graph and the horizontal bar graph in the time zone are colored in red. From 9:00 to 9:20 on the same day, Kozaburo's NEWS overall score is 6. Therefore, the discrimination unit 6 classifies the total score of Kozaburo's NEWS in the time zone into the orange group. The total score of NEWS of Kozaburo after 9:20 on the same day is 7. Therefore, the discrimination unit 6 classifies the total score of Kozaburo's NEWS in the time zone into the red group.

In addition, the display control unit 8 tells the display unit 7 that the patient's condition level is the worst among the color groups related to the total score or the measured value at the latest time point (July 10, 2017, 10:00). Controls to display the room number with the color corresponding to the indicated color group. Taking Kumiko photoelectric as an example, the color groups to which the overall score or measured value of Kumiko photoelectric belongs at the latest time point are the green group and the red group. Since the patient's condition level is worse in the red group than in the green group, the room number of Kumiko photoelectric is displayed on the display unit 7 with the color corresponding to the red group, that is, red.

Information on the discrimination method (NEWS, SOFA) and the parameter (lactate) is displayed in the section of Kotaro, but only the discrimination method may be displayed as in the display mode in the section of Koshiro.

FIG. 9 is a diagram relating to a screen displaying a change in the patient's condition at a certain point in time. The screen shown in FIG. 9 is divided into four sections. Information about each patient is displayed in each compartment. Therefore, in the screen example shown in FIG. 9, changes in the condition of the four patients can be confirmed in a list.

As shown in FIG. 9, the display unit 7 has no discrimination method name or parameter name, the latest total score or measured value obtained at the present time, and no increase, decrease, or change in the total score or measured value. A symbol indicating that is displayed. The patient name is displayed in the upper center of each section. On the left side of the patient name, the identification number corresponding to the patient is displayed. The room number corresponding to the patient is displayed on the left side of the identification number. Room numbers are given a color corresponding to a color group classified based on the overall score or numerical value. In the center of each section in the vertical direction, the name of each discrimination method or parameter arbitrarily selected by the medical staff is displayed. Below each discrimination method name or parameter name, a total score or numerical value corresponding to each discrimination method or parameter is displayed. The overall score or numerical value is given a color corresponding to the color group classified based on the overall score or numerical value. An arrow-shaped symbol (also referred to as an arrow symbol) is displayed on the right side of the total score or the numerical value.

The overall score or measurement is colored according to the color groups described above. For this reason, the overall score or measured value is visually distinguished.

The arrow symbol will be described. An upward arrow symbol indicates that the latest overall score or measurement obtained at this time is higher than the previous overall score or measurement for that time point. Conversely, the down arrow symbol indicates that the latest overall score or measurement obtained at this time is lower than the previous overall score or measurement for that time point. In addition, the horizontal arrow symbol indicates that the latest total score or measured value obtained at the present time is equal to the total score or measured value immediately before the time.

Focusing on Kotaro, the screen shown in FIG. 9 will be described in detail. The section related to Kotaro is the upper left section. In the example shown in FIG. 9, the total score of NEWS of Kotaro is 6. In this case, the discrimination unit 6 classifies the total score of the NEWS into the orange group. Since the measured value of Kotaro's respiration is 290, the discriminating unit 6 classifies the measured value into the orange group. Since the measured value of Kotaro's systolic blood pressure is 120 mmHg, the discriminating unit 6 classifies the measured value into the white group.

Next, focusing on Kotaro, the arrow symbols will be described in detail. For example, if the total score of Kotaro's NEWS immediately before the present time is 5, the total score of Kotaro's NEWS at the present time is higher than the total score of immediately before. Therefore, the discrimination unit 6 determines that the total score of Kotaro's NEWS has increased. The discrimination unit 6 transmits a signal generated based on the discrimination result to the control unit 2. Since the signal is a signal indicating that the total score of Kotaro's NEWS has increased, the display control unit 8 which is a part of the control unit 2 causes the display unit 7 to display an upward arrow symbol. Control.

For example, if the respiration of Kotaro immediately before the present time is 300, the respiration of Kotaro at the present time is lower than the value immediately before. Therefore, the discrimination unit 6 determines that Kotaro's breathing has decreased. The discrimination unit 6 transmits a signal generated based on the discrimination result to the control unit 2. In this case, since the signal is a signal indicating that Kotaro's breathing has decreased, the display control unit 8 which is a part of the control unit 2 causes the display unit 7 to display a downward arrow symbol. Control.

For example, when the systolic blood pressure of Kotaro immediately before the present time is 120 mmHg, the systolic blood pressure of Kotaro at the present time is equal to the systolic blood pressure immediately before. Therefore, the discrimination unit 6 determines that the systolic blood pressure of Kotaro has not changed. The discrimination unit 6 transmits a signal generated based on the discrimination result to the control unit 2. In this case, since the signal is a signal indicating that the systolic blood pressure of Kotaro has not changed, the display control unit 8 which is a part of the control unit 2 displays a horizontal arrow symbol with respect to the display unit 7. Control to display.

Further, the display control unit 8 controls the display unit 7 to display a room number colored based on the color group indicating that the patient is in the worst condition among the color groups related to the total score or the measured value. do. Taking Kotaro as an example, the color groups to which Kotaro's total score or measured value belongs at present are the white group and the orange group. Since the condition level of the patient is worse in the orange group than in the white group, the room number of Kotaro is displayed on the display unit 7 in a color corresponding to the orange group, that is, in a state of being colored orange.

The screens shown in FIGS. 8 and 9 display information about four patients on one screen, but are not limited to this example. For example, only information about one patient may be displayed on one screen.

The screens shown in FIGS. 8 and 9 are divided into two horizontal columns and two vertical rows, but the present invention is not limited to this example. For example, it may be divided into one horizontal column and four vertical rows. Further, the display mode of the display unit 7 may be configured to be appropriately changed by the display control unit 8 based on the size of the display unit and the like.

FIG. 10 is a diagram showing a screen in which patients are arranged for each color group. On the screen shown in FIG. 10, a plurality of patient names, a plurality of identification numbers corresponding to each patient, and a plurality of room numbers corresponding to each patient are displayed. The plurality of patients displayed on the screen are patients whose condition has been determined based on a specific discrimination method or parameter. The patient name is displayed substantially in the center of the screen in the left-right direction. The patient identification number is displayed on the left side of the patient name. The room number corresponding to the patient is displayed on the left side of the patient identification number. The room numbers are colored based on the color groups classified by the discriminating unit 6 according to the specific discriminating method or parameter. In this embodiment, patient identification information is arranged from top to bottom in the order of patients with poor condition.

When an input operation for switching the screen of the display unit 7 is input to the input operation unit 3, the operation signal is transmitted to the control unit 2. The display control unit 8 which is a part of the control unit 2 controls the display unit 7 to switch between the screens shown in FIGS. 8 to 10 based on the operation signal.

According to the above configuration, each discrimination result by the plurality of discrimination methods is colored and displayed on the display unit 7 based on the color group classified by the discrimination unit 6. Therefore, the medical worker can quickly and uniformly evaluate each discrimination result only by looking at each discrimination result displayed on the display unit 7. As described above, according to the above configuration, it is possible to reduce the load on the medical staff when the medical staff wants to comprehensively judge the change in the condition of the patient by using a plurality of discrimination methods.

Further, according to the above configuration, it is possible to evaluate while uniformly grasping the trend (trend) of biological information which is a parameter of each discrimination method.

Further, according to the above configuration, the medical staff can quantitatively and qualitatively grasp the urgency of the patient's response by confirming the numerical value of the total score and the display mode thereof.

Further, according to the above configuration, the medical worker can collectively confirm the change in the condition of a plurality of patients in a standardized display mode.
