FIG. 4 is a diagram illustrating an example of nosocomial infection information stored in the nosocomial infection information DB 16. As shown in FIG. 4, the hospital infection information DB 16 stores “room ID, doctor in charge, nurse in charge, number of patients, number of infected persons, number of vaccinated persons”.

  The “room ID” stored here is an identifier for identifying a room. The “in-charge doctor” is information for specifying the doctor in charge of the room, and the “in-charge nurse” is information for specifying the nurse in charge of the room. “Number of patients” is the number of patients admitted to the room, “Number of infected persons” is the number of patients who have been confirmed to be infected with infectious diseases, and “Number of vaccinated persons” is The number of patients vaccinated against infectious diseases. In addition, about each room, patient ID etc. which identify a patient can also be matched.

  In the example of FIG. 4, room 1-1 is a room in charge of doctor A and nurse E, 5 are hospitalized, 3 are vaccinated, and 2 are infected. It shows that. In addition, FIG. 4 shows that the room 1-1 and the room 2-1 are both in charge of the doctor A, and the room 1-1 and the room 1-3 are different from each other, but the nurses in charge are the same. I know that there is. The information stored here is set and updated by an administrator or the like.

  The movement information DB 17 is a database that stores movement information between patient rooms. FIG. 5 is a diagram illustrating an example of movement information stored in the movement information DB 17. As illustrated in FIG. 5, the movement information DB 17 stores “movement source room ID, movement destination room ID, patient”. The “movement source room ID” stored here is an identifier that identifies the room from which the patient has moved, and the “movement destination room ID” is an identifier that identifies the room to which the patient has moved, and “patient”. Is information for identifying the infected person who has moved.

  The first line in FIG. 5 shows that patient H has moved from room 1-1 to room 1-2. In addition, the movement includes a temporary movement such as an examination in addition to the movement of the hospitalized room. In addition, the patient targeted by the movement information can be a general inpatient, or can be an infectious person whose infection is confirmed among the inpatients. Further, not only the patient but also the change or movement of the doctor in charge or the nurse in charge can be counted as a management target. Further, the movement information DB 17 can further associate movement dates and times.

  The room infection risk DB 18 is a database that stores information regarding the infection risk of each room. FIG. 6 is a diagram illustrating an example of infection risk information stored in the room infection risk DB 18. As illustrated in FIG. 6, the room infection risk DB 18 stores “room ID, risk”. The “room ID” stored here is an identifier for identifying a room. “Risk” indicates an infection risk and is set, for example, in five stages. In the example of FIG. 6, it can be seen that the risk of infection is highest when the risk of the room 1-1 is 5.

  The room-to-room infection risk DB 19 is a database that stores the relationship regarding infection between rooms. FIG. 7 is a diagram showing an example of infection risk information stored in the inter-room infection risk DB 19. As illustrated in FIG. 7, the inter-room infection risk DB 19 stores “room ID1, room ID2, relationship”. The “room ID 1” and “room ID 2” stored here are identifiers that specify the room. “Relation” is information indicating the risk of infection between rooms, and is set, for example, in five stages. In the example of FIG. 7, it can be seen that the infection risk in the room 1-1 and the room 1-1 is 3.

  The control unit 20 is a processing unit that controls the entire information processing apparatus 10, and is, for example, a processor. The control unit 20 includes an infection information management unit 21, a room risk generation unit 22, an inter-room risk generation unit 23, a map generation unit 24, and a map display unit 25. The infection information management unit 21, the room risk generation unit 22, the inter-room risk generation unit 23, the map generation unit 24, and the map display unit 25 are an example of an electronic circuit such as a processor and an example of a process executed by the processor.

  The infection information management unit 21 is a processing unit that receives information about an infected person. For example, the infection information management unit 21 accepts the doctor in charge of each room in the hospital, the nurse in charge of each room, the number of patients, the number of infected persons, the number of vaccinations, etc. via the administrator terminal and the like in the hospital infection information DB 16. Store. In addition, the infection information management unit 21 accepts patient movement information and stores it in the movement information DB 17.

  The room risk generation unit 22 is a processing unit that generates an infection risk for each room. Specifically, the room risk generation unit 22 calculates the infection risk based on the number of infected persons in each room, and calculates the infection risk for each room based on the person's infection information and the movement information between the person's rooms. The infection risk is stored in the room infection risk DB 18.

  For example, the room risk generation unit 22 refers to the nosocomial infection information DB 16 in FIG. 4 and calculates the ratio of the number of infected persons in the number of patients for each room. The room risk generator 22 sets the infection risk to 5 within the range of 100% to 70%, 4 for the risk within the range of 69% to 60%, and 3 for the infection within the range of 59% to 50%. In the range of 49% to 30%, the infection risk can be set to 2, and in the case of 29% or less, the infection risk can be set to 1.

  Furthermore, the room risk generation unit 22 can increase or decrease the infection risk using various types of information. For example, the room risk generation unit 22 decreases the infection risk by 1 when the ratio of the number of vaccinations in the number of patients is 50% or more, and increases the infection risk by 1 when the ratio is less than 50%. You can also.

  As another example, the room risk generation unit 22 may refer to the movement information DB 17 to decrease the infection risk of the room where the patient has gone out by 1 and increase the infection risk of the room where the patient has entered by 1. it can.

  The inter-room risk generation unit 23 is a processing unit that calculates the strength of the relationship regarding infection between rooms. Specifically, the inter-room risk generation unit 23 calculates the strength of the relationship regarding the infection between the rooms based on the person's infection information and the movement information between the persons' rooms, and the inter-room infection risk DB 19. To store.

  For example, as shown in FIG. 7, the inter-room risk generation unit 23 first generates a combination of rooms and sets an initial value 0 to a relationship corresponding to each combination. Next, the inter-room risk generation unit 23 refers to the nosocomial infection information DB 16 and increments the relationship of the same room by the doctor in charge by one. Further, the inter-room risk generation unit 23 increases the relationship of the same room by the nurse in charge by one.

  Further, the inter-room risk generation unit 23 can increase or decrease the relationship according to the number of moving people with reference to the movement information DB 17. For example, when two patients move from the room 1-1 to the room 1-2, the inter-room risk generation unit 23 increases the relationship between the room 1-1 and the room 1-2 by two.

  The map generation unit 24 is a processing unit that generates an in-hospital three-dimensional map using infection information. For example, the map generation unit 24 refers to the floor information DB 14 to plot each floor in a three-dimensional space, and further refers to the room information DB 15 to plot each room as a node on each plotted floor. And the map production | generation part 24 changes the magnitude | size of the node corresponding to each room with reference to room infection risk DB18 according to the risk of each room. That is, the map generation unit 24 sets the size of each room so as to increase in the order of risk 1, 2, 3, 4, 5.

  Further, the map generation unit 24 connects the plotted nodes with lines (edges), and changes the line thickness based on the relationship stored in the room-to-room infection risk DB 19. For example, the map generation unit 24 sets the size of each line so that the line becomes thicker in the order of infection values 1, 2, 3, 4, and 5. Note that the map generation unit 24 draws only a room having a risk equal to or higher than a threshold (for example, 2) as a node, or draws an edge only between rooms where the relationship between rooms is equal to or higher than the threshold (for example, 2). You can also.

  Further, the map generation unit 24 specifies the spread direction of the infection using the movement information, the infection time, etc., and shows the direction on the map. For example, when the patient is moving from the room 1-1 to the room 1-2 with reference to the movement information DB 17, the map generation unit 24 refers to the room 1-1 to the room 1-2 on the three-dimensional map. The arrow is illustrated. In addition, the map generation unit 24 uses the latest date and time of the infected person in each room to show an arrow from the room with the oldest infected person to the room with the latest infected person, By connecting the latest date and time in order from the oldest, the spread direction of the infection is identified and illustrated. As another example, the map generation unit 24 can also show a line in a direction in which the risk of infection is greater for each room connected by edges.

  The map display unit 25 is a processing unit that displays the three-dimensional map generated by the map generation unit 24 on a display or the like. Further, the map display unit 25 executes rotation, enlargement, reduction, and the like of the generated map in accordance with a user operation. The map display unit 25 can also display detailed information such as the room infection risk DB 18 and the inter-room infection risk DB 19 when a room position or edge on the three-dimensional map is selected.

  FIG. 8 is a diagram illustrating an example of a three-dimensional map. In FIG. 8, it is assumed that illustration of a room with an infection risk of 1 or 2 is suppressed, and only rooms with an infection risk of 3 or more are shown. As shown in FIG. 8, the target hospital has 5 floors from 1F to 5F, and rooms with an infection risk of 3 or more are 5-1, 4-1, 4-2, 4-3, 3- 7 rooms of 2, 3-3, 2-3. In addition, the infection risk in the room 4-2 is the largest, the infection risk in the room 5-1 and the room 3-3 is the second largest, and the infection risk in the rooms 4-1, 4-3, 3-2, and 2-3. The next big thing. In addition, regarding the infection period of the infected person, since the room 5-1 is the oldest and the room 2-3 is the newest, an arrow indicating the direction of infection is illustrated from the room 5-1 toward the room 2-3. The The larger the relationship between the rooms, the thicker the lines are connected. With such a three-dimensional map, it is possible to visually confirm the position and direction of the infected person. Note that the infection direction is not limited to the arrow, and various display methods can be adopted as long as the information can specify the direction, such as east, west, south, north, and floor information.

[Process flow]
FIG. 9 is a flowchart showing the flow of processing. As shown in FIG. 9, when the process is started (S101: Yes), the room risk generation unit 22 reads the hospital infection information in the hospital infection information DB 16 (S102), and calculates the infection risk for each room (S103). ). Subsequently, the room-to-room risk generation unit 23 calculates an infection risk for each room (S104).

  Thereafter, the map generation unit 24 reads the coordinates of the floor area from the floor information DB 14 and displays them in the three-dimensional space (S105). Subsequently, the map generation unit 24 reads the center coordinates of each room from the room information DB 15 and displays them as a node in the three-dimensional space (S106).

  Then, the map generation unit 24 reads the risk (infection risk) of each room from the room infection risk DB 18 and reflects it in the size of the node (S107). Further, the map generation unit 24 reads the risk (relationship) between each room from the room-to-room infection risk DB 19, and when the threshold is exceeded, draws an edge between the rooms and reflects the magnitude of the risk on the edge thickness. (S108).

[effect]
As described above, the information processing apparatus 10 generates a three-dimensional map in which a room is a node and a relationship between rooms is an edge. The size of the node reflects the size of the room risk, and the thickness of the edge reflects the strength of the rooms. The node position reflects the physical positional relationship of the rooms. The information processing apparatus 10 can also display a layer object so that rooms on the same floor can be seen.

  In addition, the information processing apparatus 10 can visually display in which direction the infection spreads by rotating and referencing the map at various angles. Further, the information processing apparatus 10 can visually display the spread of infection by detecting the direction in which the infection is most spread and automatically rotating the viewpoint perpendicular to the direction.

Further, the information processing apparatus 10 can identify a plurality of infection directions according to the number of arrows, and can identify the number of arrows as the risk of infection direction. The information processing apparatus 10 can also specify the infection direction for each floor and display it on the map.

  Further, when there are infected persons in the room A and the room B, the information processing apparatus 10 can also draw the edge direction from the oldest to the newest, and when there are a plurality of infected persons, The direction of the edge can also be specified by comparing the old infection times or the average infection time. The information processing apparatus 10 can also draw an edge in the direction from the room A to the room B when a person (a doctor, a nurse, a patient, or the like) moves from the room A to the room B.

  Further, when there are a plurality of movements, the information processing apparatus 10 can add a score to each movement and finally draw the direction of the edge in a direction in which the score is large. The movement can include movements of doctors, nurses, patients, and the like. In the case of movement of infected patients, the score (risk, relationship) can also be controlled to increase.

  Further, the information processing apparatus 10 can specify a plane in a three-dimensional space by picking up three vectors. For example, the information processing apparatus 10 obtains a plane composed of three vectors for all combinations of three edge vectors, and obtains the sum of inner products on the respective planes for all vectors other than the three vectors. Then, the information processing apparatus 10 can determine that a plane having a higher total has a larger spread of infection, and can present a plurality of viewpoint candidates to the user in the ranking order of the total value.
