Description

  The present invention relates to a system for selecting a hospital that can accept a patient.

In recent years, a problem of refusal to accept a patient has occurred in a plurality of medical sites due to a shortage of doctors (absolute number / specialist imbalance), a shortage of beds, and the like.
As a countermeasure against such a problem, in a medical network system in Tokyo, 24 hospitals share information on the current acceptance status and respond to acceptance and acceptance of new victims. ing. Further, in Patent Document 1, the emergency vehicle arrives at the address area of the report source efficiently and in a short time based on the detailed information of the report source transmitted by the emergency report terminal, and the transport destination obtained for each transport destination Based on the information, there has been proposed a vehicle dispatch management method for an emergency vehicle that reliably and quickly transports a victim from a reporter to a transport destination.

JP 2001-325689 A

  However, in the above-mentioned medical network system, doctors are busy with medical care and the update of the shared information is delayed, so the latest situation is not reflected in the shared information, and although it is actually acceptable, it may be rejected. there were. Further, in the technique of Patent Document 1, whether or not a patient can be accepted is determined based only on transport destination information at the time of inquiry (the state of vacant beds, the number of doctors currently available, etc.), and therefore future predictions are not included. Therefore, accurate determination cannot be performed, and the range of hospital selection is narrowed.

  This invention is made | formed in view of the said subject, The main objective is to determine the hospital which can accept a sick person appropriately.

  In order to solve the above-mentioned problem, the present invention is an emergency hospital selection system, and receives an inquiry of an accepting hospital that can accept a sick person including position information of the terminal from a terminal mounted on an emergency vehicle. A management server; and a hospital server that receives an inquiry about a response time from the management server until the hospital can handle a sick person, calculates the response time, and transmits the response time to the management server. However, when receiving the inquiry of the receiving hospital from the terminal and means for storing the hospital location information in advance for each hospital, the inquiry of the corresponding time is transmitted to the hospital server for each hospital, As a response, the means for receiving and storing the corresponding time from the hospital server, the location information of the terminal included in the inquiry of the accepting hospital, and the prestored information of each hospital Based on the location information, for each hospital, a means for calculating and storing the travel time from the current position of the emergency vehicle to the hospital and the larger of the corresponding time and the travel time for each hospital Means for storing the time until the hospital can accept the patient and the minimum of the reception times of each hospital, and the hospital associated with the minimum value is selected as the receiving hospital. And means for transmitting information related to the hospital to the terminal.

  According to this configuration, when selecting a hospital to accept a patient, not only the travel time from the emergency site to the hospital, but also the response time until the hospital can handle the patient, Even if it is impossible, hospitals that can be handled after a while will be included in the options, so the range of hospital choices will be widened, and it is possible to avoid traversing due to rejection of acceptance. And, for example, even if there is a hospital that takes a long time to respond even if it is close to the emergency site, and a hospital that has a short time to respond even if it is far from the emergency site, it can actually be accepted. Since it evaluates according to the acceptance time until, it is possible to select the optimal hospital.

Further, according to the present invention, in the emergency hospital selection system, the management server is configured to accept a hospital located within a predetermined range including the location of the terminal based on the location information of each hospital stored in advance. When the minimum value is equal to or smaller than a predetermined value, the hospital related to the minimum value is selected as an accepting hospital, information on the hospital is transmitted to the terminal, and the minimum value is larger than the predetermined value. Furthermore, the range may be enlarged, and a hospital located within the range may be selected as the receiving hospital.
According to this configuration, by determining a range of hospitals to be selected as receiving hospitals, a hospital whose time for receiving a sick person is equal to or less than a predetermined value is searched for, so that the receiving time can be limited. If there is no hospital whose acceptance time is less than or equal to a predetermined value, the possibility of finding a hospital that can be immediately responded or has a short response time can be found by expanding the range and searching for a hospital.

In the emergency hospital selection system according to the present invention, when the hospital server receives the response time inquiry from the management server, the means calculates the response time of one or more doctors belonging to the hospital. And a means for specifying a minimum value among the calculated corresponding times and transmitting the minimum value to the management server as the corresponding time of the hospital.
According to this configuration, when there are a plurality of doctors in the hospital, the hospital server responds to the doctor with the shortest time until the victim can be handled, that is, the doctor who can deal with the victim the earliest. Notify the management server of the time. According to this, the hospital can best cope with the inquiry about the response time of the victim.

In the emergency hospital selection system according to the present invention, the hospital server further includes means for acquiring and storing location information of the mobile terminal as needed by communicating with the mobile terminal possessed by each doctor of the hospital. And when calculating the corresponding time, if the stored position of the mobile terminal is in the hospital, the travel time of the doctor from the position of the mobile terminal to the operating room is calculated, and the travel time is calculated. It may be stored as the corresponding time.
According to this configuration, since a doctor in the hospital is searched and the victim is dealt with, even if the doctor is not ready to respond, such as waiting in the waiting room of the operating room, if he is in the hospital Since it becomes a candidate of correspondence, the range which chooses an acceptance hospital becomes wide. Then, by calculating the travel time to the doctor's operating room, the corresponding time of the hospital can be obtained with high accuracy.

Further, the present invention is the emergency hospital selection system, wherein the hospital server stores in advance a keyword indicating a progress rate of the operation issued by a doctor belonging to the hospital during the operation, and a doctor operating the operation When voice data is acquired, when the voice data is the keyword, a surgery end time at which the surgery is finished is calculated based on the progress rate indicated by the keyword, and the calculated surgery end time is calculated as the doctor And a means for storing the information in association with each other, and when calculating the corresponding time, the current time may be subtracted from the stored operation end time, and the subtraction value may be stored as the corresponding time. .
According to this configuration, even a doctor who cannot respond immediately because of an operation becomes a candidate for correspondence, and thus the range of selection of an accepting hospital is widened. And since the doctor who is operating issues the keyword which shows the progress rate of an operation, since the time when the said operation is complete | finished is calculated, the response time of the said hospital can be calculated | required accurately.

  The present invention includes a management server and a hospital server. In addition, the problems disclosed by the present application and the solutions thereof will be clarified by the description of the mode for carrying out the invention and the drawings.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. The emergency hospital selection system 1 according to the embodiment of the present invention grasps not only the travel time of an ambulance but also the state of the hospital (the doctor, bed, operating room availability, etc.) and rescues the patient based on them. It is a system for selecting hospitals to be transported from the field. For each hospital, the ambulance travel time and the time until the hospital can respond (the time from the current time until the doctor can respond to the victim) Calculate and determine the hospital with the shortest acceptance time by taking the longer travel time and response time as the acceptance time until it becomes acceptable. Then, in order to calculate the time until the doctor becomes available, the end time of the surgery is predicted by voice recognition of a keyword indicating the progress status of the doctor during the surgery.

  According to this, even if it is not possible to respond immediately, search for a hospital that can be accommodated after waiting for a while, and by selecting a hospital to be transported considering the travel time from the site to the hospital, A hospital can be determined.

The hospital data 35A is data relating to a hospital in an area controlled by the management server 3, and includes a record including a hospital name 35A1, position information 35A2, and a server address 35A3. The hospital name 35A1 is the name of the hospital in the jurisdiction area. The position information 35A2 is information indicating the position of the hospital, and is, for example, latitude or longitude. The server address 35A3 is the network address (MAC [Media Access Control] address, IP address, etc.) of the hospital server 4 installed in the hospital, and is used for the management server 3 to communicate with each hospital server 4.

  FIG. 4B shows the configuration of the target hospital data 35B. The target hospital data 35B is data related to a hospital in the search range specified by the management server 3, and includes records including a hospital name 35B1, a distance 35B2, a travel time 35B3, a corresponding time 35B4, and an acceptance time 35B5. The hospital name 35B1 is the name of the hospital extracted from the hospital data 35A by the position information 35A2 according to the search range. The distance 35B2 is a movement distance between the hospital and the emergency site, and a distance along the movement route is set. The travel time 35B3 is the travel time from the emergency site to the hospital, and at least a value obtained by dividing the travel distance by the average speed of the ambulance is set. However, the travel time 35B3 may reflect the congestion situation on the travel route. The response time 35B4 is the time until the hospital can respond to the patient from the present time, for example, the time until the doctor in charge belonging to the hospital can respond. The acceptance time 35B5 is a time until the patient is actually accepted and treatment is possible, and a larger (not smaller) value is set between the movement time 35B3 and the corresponding time 35B4. In other words, if the ambulance arrives at the hospital, the patient will wait if the doctor cannot respond, and if the ambulance does not come to the hospital even if the doctor is available, the doctor will wait. Those who take time will be the actual acceptance time.

  FIG. 4C shows the configuration of the search range data 35C. The search range data 35C is data for the management server 3 to specify the search range, and includes a record including the distance 35C1.

Then, when the operation is completed, the record is deleted.

≪System processing≫
FIG. 7 is a flowchart showing hospital search processing of the management server 3. The management server 3 receives a hospital inquiry from the vehicle terminal 2 mounted on the ambulance at the emergency site, searches for the optimal hospital, and performs a process of notifying the vehicle terminal 2.

  First, the management server 3 receives an inquiry about an accepted hospital including data on the current position and a desired medical department from the vehicle terminal 2 (S701). The current position is data obtained from GPS position information received by the vehicle terminal 2 at the site where the ambulance arrived. The desired medical department is data input by the emergency crew to the vehicle terminal 2. Next, the search range data 35C in the storage unit 35 is referred to, and the search range for the hospital is determined (S702). For example, when 5 km of the distance 35C1 is selected from the search range data 35C, the search range is determined within a circle with a radius of 5 km centered on the current position received from the vehicle terminal 2. The search range guarantees to some extent the reception time from the current time until the emergency patient can be received at the hospital. For example, the reception time is less than the maximum travel time (for example, 10 minutes) within the search range. Assume that The maximum movement time is the maximum time required for moving from the current position of the vehicle terminal 2 to the boundary of the search range.

  Subsequently, the management server 3 refers to the hospital data 35A and map data 35D in the storage unit 35, extracts hospitals within the determined search range, and stores the hospital name 35B1, distance 35B2 and movement to the target hospital data 35B. Time 35B3 is set (S703). In the extraction of the hospital, the hospital name 35A1 located within the search range is specified by the position information 35A2 of the hospital data 35A, and set to the hospital name 35B1 of the target hospital data 35B. For the distance 35B2, an optimum route (for example, the shortest route) from the current position to the hospital is specified by the map data 35D, and a distance along the route is set. In the travel time 35B3, the time when the route is moved at the average speed of the ambulance is set, but the traffic congestion state of the road may be reflected. The above process can be realized by applying a car navigation system.

  Then, the management server 3 transmits a response time inquiry including the medical department to the hospital server 4 of one hospital among the hospitals within the search range set in the target hospital data 35B of the storage unit 35. (S704). In this case, the server address 35A3 stored in the hospital data 35A is used as the destination address. As a response to this, the hospital server 4 sends a message indicating that immediate response is possible or not possible, or a specific response time.

  If the hospital server 4 can respond immediately (Y in S705), the management server 3 selects the hospital and notifies the name of the hospital and its location information to the vehicle terminal 2 that has received an inquiry from the receiving hospital. At the same time, the hospital server 4 of the selected hospital is notified that an ambulance is scheduled to go (S711). At this time, the hospital server 4 calls a doctor who can respond immediately through the portable terminal, and requests the emergency patient. If the hospital server 4 cannot respond (N in S705 and Y in S706), the determination process in S708 is performed (details will be described later).

  If the specific response time is included in the message received from the hospital server 4 (N in S706), the management server 3 sets the response time to the response time 35B4 in the record of the target hospital data 35B. The larger one of the response time 35B4 and the movement time 35B3 is set as the reception time 35B5 (S707). Then, it is determined whether or not an inquiry has been made to all the hospital servers 4 within the search range set in the target hospital data 35B of the storage unit 35 (S708). If there is a hospital server 4 that has not made an inquiry (N in S708), an inquiry is made (S704).

  If all the hospital servers 4 within the search range have been inquired (Y in S708), the management server 3 specifies the minimum value among the reception times 35B5 set in the target hospital data 35B of the storage unit 35 ( S709). And it is determined whether the minimum value is below a predetermined value (S710). The predetermined value is, for example, the maximum travel time within the search range. If the minimum value of the acceptance time is larger than the predetermined value (N in S710), it means that the response time of the hospital within the search range is long. Therefore, if the search range is expanded, immediate response is possible or the response time is short. Since there is a possibility of finding a hospital, the search range is expanded (S712), and a hospital within the search range is extracted and set (S703). If an appropriate hospital is not found even when the search range is expanded, the appropriate hospital is selected by relaxing the determination condition of S710.

  When the minimum value of the acceptance time is equal to or less than the predetermined value (Y in S710), the management server 3 selects the hospital and supplies the hospital name and its position information to the vehicle terminal 2 that has inquired the acceptance hospital. In addition, the hospital server 4 of the selected hospital is notified that an ambulance is scheduled to go (S711). At this time, the vehicle terminal 2 receives the hospital name and its position information from the management server 3 and displays them on the display. The ambulance crew members see the hospital name and its position information displayed on the display of the vehicle terminal 2 and start an ambulance toward the hospital. In addition, the hospital server 4 receives a notification that an ambulance is coming from the management server 3, calls the doctor related to the minimum value of the reception time through the portable terminal, and requests the emergency patient to respond. The doctor receives a call from the mobile terminal, moves to a waiting room in the operating room, and waits for an emergency patient to come.

  FIG. 8 is a flowchart showing the inquiry handling process of the hospital server 4. The hospital server 4 receives the inquiry of the response time from the management server 3, confirms the situation of the equipment in the hospital and the doctor in charge, and sends a message indicating that immediate response is possible or not possible or a specific response time is included in the management server The process of transmitting to 3 is performed.

  First, the hospital server 4 refers to the department doctor data 45A in the storage unit 45 and determines whether there is a medical department included in the inquiry from the management server 3 (S801). If there is the medical department (Y in S801), it is determined whether or not there is an empty bed by referring to the empty bed number 45B1 in the empty status data 45B (S802). If the number of vacant beds 45B1 is not zero and there is an vacant bed (Y in S802), for example, it is determined whether or not an emergency patient can be handled immediately from the availability of a doctor in the waiting room or the operating room (S803). If immediate response is possible (Y in S803), a message indicating that immediate response is possible is transmitted to the management server 3 (S810).

  If it is not possible to respond immediately (N in S803), the hospital server 4 refers to the department doctor data 45A and the hospital map data 45D in the storage unit 45, and the doctor who is not operating in the hospital, that is, by calling It is determined whether there is a doctor who can respond (S804). In this determination, it is checked whether or not the current position 45A3 of the doctor is within the range of the in-hospital map data 45D for each belonging doctor name 45A2 of the medical department 45A1 in the department doctor data 45A. The doctor who is operating is handled separately from “the doctor in charge” in the determination of S804.

  If there is a doctor in charge in the hospital (Y in S804), it is determined whether or not there is an empty operating room with reference to the number 45B2 of empty operating rooms in the empty status data 45B (S805). If the number of empty operating rooms 45B2 is not zero and there is an empty operating room (Y in S805), refer to the department doctor data 45A and the hospital map data 45D in the storage unit 45, and calculate the hospital doctor's response time, The doctor name 45C1 and the correspondence time 45C2 of the doctor correspondence time data 45C in the storage unit 45 are set (S806). The correspondence time of the in-hospital doctor calculates the travel time along the passage in the hospital from the current position 45A3 of the doctor to the operating room. If there is no doctor in charge in the hospital (N in S804), or if there is no empty operating room (N in S805), the process in S806 is skipped.

  Subsequently, the hospital server 4 refers to the department doctor data 45A and the doctor-specific end time data 45F to determine whether there is a doctor in charge during the operation (S807). In this determination process, it is checked whether or not there is a doctor included in the doctor name 45F1 of the doctor end time data 45F among the doctor names 45A2 of the department 45A1 in the department doctor data 45A. If there is a doctor in charge during the operation (Y in S807), the time until the end of the operation is calculated by subtracting the current time from the predicted end time 45F4 of the end time data 45F for each doctor, and the doctor of the doctor corresponding time data 45C A name 45C1 and a corresponding time 45C2 are set (S808). If there is no doctor in charge during the operation (N in S807), the process of S808 is skipped.

  Then, the hospital server 4 determines whether or not there is a doctor in charge corresponding to the emergency patient by checking whether or not one or more records are set in the doctor response time data 45C of the storage unit 45 (S809). If there is a corresponding doctor in charge (Y in S809), the minimum time is specified out of the response time 45C2 set in the doctor response time data 45C, and a message including the minimum response time is notified to the management server 3 (S811). ). When there is no medical department (N in S801), there is no vacant bed (N in S802), or there is no corresponding doctor in charge (N in S809), a message indicating that the management server 4 is not available Is notified (S812).

  FIG. 9 is a flowchart showing the operation end time prediction process of the hospital server 4. For example, the hospital server 4 predicts the surgery end time when receiving a surgery start message from a terminal installed in the operating room, and then acquires a keyword indicating the progress status from the doctor during the surgery. The process of updating the predicted value of the operation end time is performed based on the above. Note that the inquiry response process from the management server 3 in FIG. 8 and the operation end time prediction process in FIG. 9 are executed asynchronously as separate tasks in the processing unit 44 of the hospital server 4, and the operation end time prediction process is predicted. An operation is performed in which an end time is set and the inquiry handling process refers to the predicted end time.

  First, the hospital server 4 obtains the doctor name, the technique name, and the start time included in the surgery start message, and sets the doctor name 45F1, the technique name 45F2, and the start time 45F3 in the doctor end time data 45F ( S901). By adding the record in this way, it can be understood that the doctor has started the operation. Next, referring to the technique-specific keyword data 45E, the standard time 45E6 of the technique name 45E1 is added to the start time 45F3, and the added value is set to the prediction end time 45F4 (S902). In the example of FIG. 6, the standard time 45E6 of the surgical procedure I is 60 minutes and the start time 45F3 of the doctor X performing the surgical procedure I is 13:00, so the predicted start time 45F4 is temporarily set to 14:00.

  And the hospital server 4 determines whether the audio | voice was received from the microphone installed in the operating room (S903). If the voice has been received (Y in S903), the doctor name 45A2 is identified from the corresponding voice pattern 45A4 by referring to the department doctor data 45A in the storage unit 45, and the doctor is referred to by the doctor end time data 45F. The technique name 45F2 is specified from the name 45F1 (S904). The identification of the doctor name is not limited to the method based on the voice pattern. For example, from the schedule of the operating room where the microphone receiving the voice is installed, the doctor who is operating in the operating room at that time The name may be specified. Next, it is determined whether or not the received voice is a keyword (S905). In this determination process, it is checked whether or not the voice is one of the 30% keyword 45E2, the 50% keyword 45E3, the 80% keyword 45E4, and the 100% keyword 45E5 with reference to the keyword data 45E by technique.

  If the voice is a keyword (Y in S905), it is determined whether it is a 100% keyword (S906). If it is a 100% keyword (Y in S906), it means that the operation has ended, and therefore the record of the doctor name 45F1 is deleted from the doctor end time data 45F (S907). If the keyword is not 100% (N in S906), since the voice is one of the 30% keyword 45E2, the 50% keyword 45E3 and the 80% keyword 45E4, the predicted end time is calculated according to the corresponding keyword, and the time Thus, the predicted end time 45F4 of the doctor-specific end time data 45F is updated (S908), and the process returns to the voice reception determination process (S903).

  In the process of calculating the predicted end time, for example, if the voice is “half-end”, the surgery is 50% complete because the keyword data 45E by the technique is a 50% keyword. If the current time at that time is 13:35, 35 minutes (50% in the first half) have passed since 13:00 of the start time 45F3, and it is assumed that the operation proceeds at the same pace. The end is predicted to be 14:10 obtained by adding 35 minutes (50% of the second half) to 13:35 of the current time. In general, if Y minutes have elapsed from the start time when the X% keyword is received, a predicted value of the remaining time until the end is obtained by Y * (100−X) / X.

  When no voice is received from the operating room (N in S903) or when the received voice is not a keyword (N in S905), the hospital server 4 returns to the voice reception determination process (S903).

  Note that the processing of S903 to S908 is not necessarily the same as the processing of S901 to S902, and when a plurality of operations are performed in parallel, audio is received from microphones in a plurality of operating rooms in S903. Therefore, the processing of S904 to S908 is sequentially executed with each voice reception as a trigger.

  In the above embodiment, in order to make each device (terminal and server) in the emergency hospital selection system 1 shown in FIG. 1 function, a program executed by the CPU is recorded on a computer-readable recording medium, and the recording is performed. The emergency hospital selection system 1 according to the embodiment of the present invention is realized by causing the computer to read and execute the program. In this case, the program may be provided to the computer via a network such as the Internet, or a semiconductor chip or the like in which the program is written may be incorporated in the computer.

  According to the embodiment of the present invention described above, a hospital that can receive an emergency patient can be appropriately determined. Whether the doctor can respond to an emergency patient is calculated not only in the current state, but also in the future, including how long the doctor will be able to respond, and the hospital response time is calculated. A wide range of hospitals can be considered. According to this, it is possible to prevent useless time from elapses due to the rotation state. In addition, by recognizing the voice uttered at every milestone by the doctor during the operation, the end time of the operation is predicted based on the keyword indicating the progress of the operation, thus preventing the doctor from forgetting to enter the progress status. It is possible to obtain the hospital response time with high accuracy.

<< Other embodiments >>
As mentioned above, although the form for implementing this invention was demonstrated, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes equivalents thereof. For example, the following embodiments can be considered.

(1) In the above embodiment, the management server 3 has described that the larger of the travel time and the corresponding time is set as the acceptance time, and the hospital with the smallest acceptance time is selected. You may apply. For example, a hospital with a short response time, a hospital close to the site, a hospital with a low medical cost, or the like may be selected from hospitals located within the search range.

(2) In the above embodiment, as shown in S807 of FIG. 8 or S901 of FIG. 9, the determination as to whether or not there is a doctor who is operating is performed by using the data set by the terminal input operation of the doctor who starts the operation. Although described as being performed with reference, it may be performed by another method. For example, it is conceivable to detect that an operation is being performed by sound, video, weight, device operation, lighting of a lamp, or the like in an operating room.

(3) Instead of setting the progress rate for each keyword as in the above embodiment, the standard time for each keyword and the overall standard time may be set for each technique. In this case, the total predicted time = the total standard time * the actual elapsed time / the standard time, and the remaining time = the total predicted time−the actual elapsed time.
