 The present invention relates to an emergency medical information system for selecting a severity classification and transfer hospital, and more specifically, the first aid activity log information prepared during emergency response in pre-hospital emergency situations is input through a web application (web applicaion). The emergency medical information system determines the severity classification of patients and selects the optimal transport hospital for the patient.

The emergency log is a record of the patient's condition and first aid before the paramedics arrive at the medical institution.

Triage refers to the classification of patients by symptom to prioritize first aid and patient transfer. That is, when a large number of patients occur, it is necessary to provide the best medical care to a large number of patients with a limited number of people, so even if you are not a specialist, the priority of first aid and transfer is given by classifying the patient's condition.

In emergency cases, patients requiring urgent first aid account for 10-15% of all emergency cases. The prognosis of the patients is reported to be good when the patients are transported directly to a hospital which can be treated according to the severity. In this sense, severity classification is an important area of emergency medical care. However, emergency personnel who work outside hospitals or medical workers who work in small and medium hospitals do not have sufficient clinical experience or academic knowledge about emergency medical care. Often, severity cannot be assessed quickly.

In addition, pre-hospital conditions have limited testing instruments available and limited physical examinations. In this respect, the occurrence of the event or the symptoms of the patient's complaints may be an easy basis for acquiring the patient, while being easier to acquire than other information. When the information is initially identified, the practical content can not only help to determine the pre-hospital severity of the patient, but also help to access the disease effectively when the diagnosis is made later.

The emergency medical system has established an organic organizational system for evacuation and treatment of patients so that they can provide appropriate medical care as soon as possible when an emergency patient occurs due to an accident or an unexpected mass disaster. It consists of three stages, such as evacuation and hospital. All of these processes must be built in a coherent system under mutually cooperative mechanisms to ensure proper connection between the accident site, the transportation process and the hospital emergency room.

 In this situation, triage is a function to rank and classify patients who need medical treatment in order to efficiently allocate limited medical resources. By doing this, non-emergency patients are primary and secondary hospitals, and emergency patients are tertiary hospitals. The system can be transferred to the center to provide an efficient medical system and provide a satisfactory treatment to patients.

However, the reality is that hospitals to be transferred are determined by geographical proximity or hospital awareness regardless of patient condition. This may be due to the emotional aspect of the medical care of patients or guardians in Korea, but it is also difficult to apply the severity in pre-hospital emergency situations. This is more important than the limitations of the equipment or resources available and the complexity of the severity classification system, which means that there is not enough time to allocate enough time for severity classification at times that are insufficient for patient status and treatment in emergencies.

 Therefore, the severity classification system is made only by recording the patient's condition without having to know the severity classification system. Based on this, a system for automatically selecting the transfer hospital is required.

 In this regard, the present invention receives emergency activity log information prepared in case of emergency rescue in a pre-hospital emergency via a web application to determine the severity classification of patients based on this, and provides an emergency medical information system to select the optimal transport hospital for the patient. do.

To do this, it is necessary to set up an appropriate first aid log for the severity classification system based on the information available to patients in pre-hospital emergencies. In particular, in setting the format of the emergency log, it is difficult to use various diagnostic devices such as blood tests or radiation devices when transferring medical institutions by ambulance, and there are problems such as limitations of medical knowledge of emergency medical workers. In all situations, it is difficult to expect a diagnosis of the patient's condition.

In the present invention, the Manchester triage system (hereinafter, referred to as 'MTS') classification system for performing severity classification based on the symptoms and signs of the patients was selected. In the MTS classification system, the severity classification results of the patient are classified into five categories: immediate, emergency, emergency, semi-urgency, and non-urgency. They are classified into groups and each group has a target time for the appropriate treatment. The time value is immediate ('0') for immediate treatment patients (immediate), less than 10 minutes for emergency patients, less than 60 minutes for emergency patients, and semi-urgency ) Within 120 minutes and non-urgency is 240 minutes.

The technical problem to be achieved by the present invention is to provide an emergency medical information system that receives the first aid activity log information through a web application to determine the severity classification of the patient and select the optimal transport hospital for the patient accordingly.

Another technical problem to be achieved by the present invention is to provide information to classify the severity while maintaining the marking form of a conventional first aid journal, which is easy to use, and provides a first aid journal consisting of computerization There is.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the emergency medical information system for selecting the severity classification and transfer hospital according to an embodiment of the present invention will be described in detail.

1 is a schematic configuration diagram for explaining the configuration of the emergency medical information system for selecting the severity classification and transfer hospital according to an embodiment of the present invention, an emergency rescue system (100), a regional emergency medical information center server 200 It is provided with a transfer hospital (290).

The emergency rescue system 100 prepares and stores an emergency rescue journal, such as an emergency log, and reports it to the server 200 of the regional emergency medical information center, and from the regional emergency medical information center server 200 Receive information from medical institutions. The emergency rescue system 100 includes an input unit 110, a memory unit 120, an operation processing unit 130, and a display unit 190.

The input unit 110 inputs information according to the emergency log.

The operation processing unit 130 stores the emergency activity log information input from the input unit 110 and receives the information of the emergency medical institution in the area from the regional emergency medical information center server 200 and calculates and processes the transfer hospital 290 Select and transmit the first aid activity log information to the selected transfer hospital (290). That is, the calculation processing unit 120 determines the severity of the patient from the emergency activity log information, and selects adjacent hospitals available based on the location of the patient according to the severity classification result and displays it on the display 130. The stretching processing unit 130 is the reception management unit 135, the past history unit 140, the incident situation unit 145, observation inspection unit 150, patient group management unit 155, hospital selection location management unit 160, hospital classification management unit 165.

The reception management unit 135 manages a reception management area of the computerized first aid activity log. The reception management unit 135 fills out the items of the emergency rescue journal according to the patient's condition, so that the information according to the patient's condition, that is, the information related to the notification and reception of the emergency rescue, the information of the time of the rescue activity process and the patient Information related to the transfer, information about other statistics and management are input and stored, and the patient's gender and age information input by the reception management unit 135 is transmitted to the patient group management unit 155 for severity classification, and the reception management unit 135 Transmit the patient's occurrence location in the hospital selection location management unit 160.

The past medical history unit 140 manages the past medical history area of the patient of the computerized first aid activity log. Past medical history unit 140 transmits the past medical history information of the patient input from the emergency medical personnel to the patient group management unit 155.

The incident situation unit 145 manages the incident situation area of the computerized emergency log. The incident situation unit 145 transmits the incident situation information input from the emergency medical personnel to the patient group management unit 155.

Observation inspection unit 150 manages the observation inspection area of the computerized first aid activity log. Observation inspection unit 150 transmits the observation inspection information input from the emergency medical technician to the patient group management unit 155.

The patient group manager 155 classifies the severity. The severity classification of patients is divided into immediate treatment group (time value is immediate), emergency patient group (time value is within 10 minutes), emergency patient group (time value is within 60 minutes), and other groups.

That is, according to the severity classification result, the patient is one of the immediate treatment group, the emergency group, the emergency group, the semi-urgency and the non-emergency group. Are classified.

Hospital selection location management unit 160 receives emergency medical institution information from the regional emergency medical center 200, and determines the adjacent hospital. That is, the hospital selection position management unit 160 receives information from the regional emergency medical center 200, adjacent hospital information of emergency medical centers and emergency medical institutions, and adjacent hospital information of internal medicine, surgery, pediatrics, obstetrics and gynecology, and other departments.

The hospital classification management unit 165 receives the severity classification result from the patient group management unit 155, receives the adjacent hospital information from the hospital selection position management unit, and assigns the corresponding hospital classification to the corresponding patient classification.

The immediate treatment group (Immerdiate group), the emergency patient group (Emergency group), and the emergency patient group (Urgency group) are regarded by the emergency medical institution / center 290 and other patients are regarded as non-emergency patient groups and assigned to the on-call medical institution. Meanwhile, in the severity classification, each group has a corresponding target time, and the optimal time is set within the corresponding distance radius by converting the time value into a distance. At this time, the immediate medical treatment group (Immerdiate group) is set to the nearest emergency medical institution, the emergency patient group (Emergency group) is set up an emergency medical institution within a radius of 5km, and the emergency group is a radius of 30km away Emergency medical institutions are set up, and other groups are not strongly related to the target time in the emergency situation, so the medical care institutions are divided into internal medicine, surgery, pediatrics, gynecology, orthopedics, and other departments. Is assigned. When the average speed of the ambulance is regarded as 30 km / hr, the distance value within 5 km and within 30 km may vary.

The memory unit 130 receives and stores emergency activity log information from the operation processing unit 120.

The display 190 displays emergency activity log information.

The regional emergency medical information center 290 transmits the information of the emergency medical institution in the regional area to the emergency medical emergency system 100 when a request is received from the emergency medical emergency system 100.

 The transfer hospital 290 is a transfer hospital selected from the emergency rescue system 100, can be largely divided into an emergency medical institution 300 and on-call medical institution (400).

The emergency medical institution 300 is an emergency medical institution 300 is set according to the severity classification and time value of the patient in the immediate treatment patient group (Immerdiate group), the emergency patient group (Emergency group), the emergency patient group (Urgency group).

The on-call medical institution 400 does not have much relation with the target time in the case of semi-urgency and non-emergency group, so the on-call medical institution is largely in medicine, surgery, pediatrics, gynecology, orthopedics, When the group is selected and the relevant group is selected, all on-the-job medical institutions in the area are displayed to set up the desired on-the-job medical institution 400 among them.

In the present invention, at least basic medical knowledge is required in order to perform the severity classification. Therefore, the subject who performs the severity classification in the pre-hospital emergency is regarded as an emergency rescuer, and the transport situation to the hospital by an ambulance is the subject of the present invention. .

The format of the first aid activity log of the present invention is the content of information that can be obtained to the patient in the pre-hospital emergency, so that the severity can be classified only by this information, and the MTS performs severity classification based on the symptoms and signs of the patient. Use a classification system.

Based on the analysis of the items of the first aid activity log currently used to apply the MTS severity classification system to the first aid activity log, the first aid activity log of the present invention means what each item of MTS means. Area information was divided into 4 areas of the observation area and observation inspection area, and specific details were reset according to the area. It also considered the work capabilities of emergency rescue workers in Korea and the equipment status of ambulances.

Table 1 is a table in which each item of the first aid activity log is divided into four areas of a reception management area, a past medical history area, an incident situation area, an observation inspection area, and the sub items are allocated.

Item Subitems Reception area Report date, dispatch time, on-site arrival time, on-site departure time, hospital arrival time, return time, reporter's personal information, report method, disaster jurisdiction, dispatch type, patient personal information, occupation, address of patient's occurrence, guardian's personal information, patient transfer , Untransfer history, transporter Past medical field case history Incident Situation Area Patient Symptoms, Traffic Accidents, Intentional Status, Patient Occurrence Types Observation Consciousness status, pupil reaction, vital signs, accident site, severity classification, paramedic evaluation, first aid history, physician guidance

The reception management area (Reg_mag) consists of information related to the notification and reception of emergency rescue, information to confirm the time of rescue activities, information related to patient transfer, and other statistics and management. In other words, the reception management area includes report date, dispatch time, site arrival time, site departure time, hospital arrival time, return time, reporter's personal information, reporting method, disaster jurisdiction, dispatch type, patient personal information, occupation, patient's address, and guardian. It consists of data such as personal information, patient transfer history, non-transfer history and sender. From a medical point of view, the main thing that can be obtained in the reception area can be information about the patient's personal information such as the patient's gender / age.

The Med_his domain is an area for obtaining information about a patient's existing disease from a patient or guardian.

Inc_situ domain is the reason for the patient's emergency. It is an area that describes the specific situation when an incident occurs and is identified by the guardian or the patient. The event situation area consists of data such as patient symptoms, traffic accidents, intentions, and types of patient occurrences.

Obs_exam domain is an area where emergency medical personnel can grasp the patient's condition based on objective examination or observation. Observation and examination area consists of data such as consciousness status, pupil reaction, vital signs, accident site, severity classification, first aid evaluation, first aid history, physician guidance.

In the present invention, the first aid activity log has low sensitivity by forming a high-sensitivity quality item so that patients at high risk are classified as patients at low risk, thus losing the appropriateness of treatment and time and material. To prevent waste.

Table 2 is a table showing the severity classification system of the present invention.

MTS Item Incident Situation Area Observation Chest pain; Heart pain Chest pain, heart pain Chest pain; non-ideal pulse rate Chest pain Pulse rate> 120 or pulse rate <60, ECG headache; Tender side headache Tenderness observation of temporal lobe headache; Suspected meningitis headache Temperature> 37.5, stiff neck observation, rash of skin

Table 2 is a reconstruction of the MTS severity classification system based on the results of the analysis of the information of the emergency log. For example, in case of chest pain patients with abnormal heart rate in MTS severity classification, the case of chest pain in the event situation area and pulse rate in the observation area were more than 120 times or less than 60 times or abnormal results were observed in ECG. Meanwhile, the MTS triage system uses the Glasgow Coma Scale (hereinafter referred to as the GCS) method to assess the mental state (M / S) of patients and uses the Triaged-revised trauma score. (Hereinafter referred to as TRTS), but the situation in Korea uses the method of consciousness (alert, response to verbal order, response to pain, unresponse) (hereinafter referred to as AVPU). Based on the studies conducted, the triage score (hereinafter referred to as TS) for traumatic patients and the modified triage score (hereinafter referred to as MTS) for non-traumatic patients are applied to the present invention. did. At this time, MTS divides the revised trauma score (RTS) into three groups, but since the method of mental state evaluation is different, such a system cannot be introduced as it is, and therefore, in the TS and MTS of the present invention, the normal group and the immediate treatment patient group (Immediate) group into two groups. In this case, the patient may be classified as an emergency group in the original MTS severity classification, but may also be classified as an immediate treatment patient group in the present invention, but prevents false negatives in the evaluation. The meaning of triage was different from that of the application. In addition, the MTS classification system excludes these items because there are items that are difficult to diagnose in pre-hospital emergencies such as umbilical cord porlapse.

Table 3 is a table showing the sub-items added in the present invention for severity evaluation.

 Existing first aid journal subentry Newly created subitems Reception area Report date, dispatch time, on-site arrival time, on-site departure time, hospital arrival time, return time, reporter's personal information, reporting method, disaster jurisdiction, dispatch type, patient personal information, occupation, address of patient's occurrence, guardian's personal information Non-transfer history, sender, statistics  Same as existing Past medical field Past history Same as existing Incident Situation Area Patient symptoms Trauma cause, trauma cause, additional query 1, additional query 3 Observation Paramedic evaluation of accident site Physical examination item classification table, ECG, hearing sound, Glucose, Skin test, additional query 2

 Table 3 is grouped to display the results of items derived through the analysis of severity classification.

The reception management area and the past medical history area are the same as the conventional one.

In the event situation, the symptoms and signs of the patient can be divided into the causes of the trauma and the causes of the trauma, depending on the cause, and additional information items are included in the other questions 1 and 3.

In the observation area, brief examinations were presented in a table to indicate the anatomical location of the human lesion. Detailed tests are presented separately. In addition, the remaining test items were included in the other questions.

In the present invention, in the modeling of the emergency log and the construction of a web-based system, the relationship between items in each area in the reception management area, the past medical history area, the incident situation area, and the observation inspection area Modeled with a class diagram, and based on the results, we built a web application based on the Application Service Provider (ASP). The Internet-based ASP form is an effective solution for emergency medical information systems in that it can be easily integrated with other medical information systems. That is, the present invention has an advantage of organic integration with various other medical information systems by building a web application based on ASP.

Figure 2 is an illustration of an example of the relationship between the items made for severity classification in the present invention. In particular, Fig. 2 shows items having a connection with pain.

In Figure 2, the pain pattern is divided into abdominal pain, heart pain, headache, back pain.

The sub-items of abdominal pain include personal information, fertility, persistent vomiting, mucus and bloody stool.

Subtypes of heart pain include chest pain and meningococcal abnormalities.

The sub-items of headache include light terror, temporal tenderness, body temperature, neck stiffness, and skin rash.

The sub-items of low back pain include ambulance and direct trauma.

This linkage shows that information of one item is determined by the severity of information linked to other items. For example, in patients with headache, the severity can be determined by the severity of the pain, but even when the pain is not severe, the severity may be determined by stiff neck, high fever, light fright, and skin rash. It is.

3 is a class diagram illustrating a relationship analysis between items for severity classification in the present invention.

In FIG. 3, two types of stereo types are used to indicate the relationship between classes: a subscription (<< subscribe >>) and a delive (<< derive >>). A subscription (<< subscribe >>) indicates that when a particular event occurs in one class it notifies the other class to which it is connected. Delive (<< derive >>) indicates that a new information can be derived based on information input from another class.

In the development type class, it is determined whether the patient's development type is a trauma or a traumatic cause. If the trauma is identified as the cause, the item corresponding to the patient is selected in the traumatic cause class.

In most traumatic classes, severity classification can be determined without additional information (e.g., if a fall> 3m is selected, it will be identified as an emergency patient group without any other information), but if there is a trauma in the severity classification and an unconscious past, If trauma is selected from the occurrence type class, it should be identified and entered into the history of unconsciousness in the additional query 1 class regardless of the input contents.

If a traumatic cause is selected in the incidence type class, an item corresponding to the patient in the traumatic cause class should be selected.

Items that can be classified as severity by the relationship between one item in the traumatic cause class or other items in the class (eg, those whose severity is determined by one item: cardiac arrest, dyspnea, relationships between other items) Severity is determined by the case of abdominal pain and hemoptysis), but some items should be determined by the relationship between different classes.

In the pain symptom class, if pain-related items (backache, headache, abdominal pain, chest pain) are selected in the traumatic cause class, the pain level, radiating pain, repulsive pain, and cycle should be determined.

In the bleeding symptom class, if the items related to bleeding (hemoptysis, vaginal bleeding, blood of stool, etc.) are selected in the traumatic cause class, the degree of bleeding should be identified.

In the patient personal information class, sex and age are judged. Women 12 years old and 50 years old or younger are judged to be females of childbearing age. do.

In the past history class, patients with behavioral or hypersensitivity reactions in the traumatic and external causes class will determine whether there is a history of major psychiatric disorders or a severe allergic history in the past history.

In the ECG class, chest pain is selected in the traumatic and external causes class, and in this class, MI / Angina should be checked.

If the Glucose class has no response / adverse reactions selected in the traumatic cause class, check the BST to determine if it is more than 300 or less than 70. Also, if the M / S is abnormal in the vitality test, check whether it is 200 or more. Must see

The pupil reaction class should identify what the pupil state is when the M / S is abnormal in the vital signs and when the no response / adverse reaction item is selected in the traumatic cause class.

Skin class is used to detect rash or purpura in patients with suspected meningitis or intracranial hematoma (dementia), or to determine the degree of dehydration in patients with suspicion of dehydration. Necessary information may be identified.

Cheongjinum class is used to determine whether Wheezing is suspected in asthmatic patients or inhalation injury in patients with suspected asthma.

In the additional query class, additional queries are requested when specific information is accepted from the traumatic cause class. For example, if a patient complains of chest pain and a chest pain is selected in the extratraumatic area, it should be identified in Pain 3 (cardiac pain).

In addition, patients determined to behave abnormally in the traumatic cause class should be aware of the possibility of self-injury or injury in question 1 of the other questions. If the other miscellaneous classes contain information related to the event situation area, the other miscellaneous classes are those with information related to the observational examination area. For example, it is necessary to determine whether there is an abnormality in the area when the patient has a fall in the traumatic cause class or to determine whether the bladder inflate in a patient with urination disorder in the traumatic cause class.

On the other hand, regardless of other classes, the class can determine the severity based on its own information. For example, the severity can be determined according to the bleeding information in the bleeding symptom class without the information of the traumatic cause class, and in the past history class, the severity can be determined by the information alone.

The physical examination class and the vital signs are classes that are not related to other classes but must be performed regardless of the patient's condition.

The MTS / TS class identifies the vital signs of a patient as a numerical value. The trauma patient is judged by the TS, and the trauma patient is determined by the MTS calculation. (MTS (Modified triage score) ≤ 11 TS (triage score) ≤ 8 Immerdiate group) On the other hand, MTS needs information about chest pain to calculate, so it is necessary to know whether to input chest pain items in 3 of other materials.

In other words, in case of occurrence type class, if the cause of patient's symptom is caused by trauma or other cause other than trauma, and input the relevant information, the item that needs additional information by <scribe> relationship They receive the necessary information through the corresponding additional query class. In the traumatic cause class, the items that need additional information for severity receive the corresponding test result or past medical history information by the subscription relationship.

Based on the information received in this way, the severity judgment class executes the severity classification through the de-live (<< derive >>) relationship.

Figure 4 is an example of an emergency log implemented as a web application in the present invention.

4 illustrates a part of a screen in which an emergency log is implemented as a web application. Considering the fact that the emergency log is used in the field, the items are arranged and screened as closely as possible to the emergency log being used. If it is difficult to express the existing paper-type first aid journals on the web screen as much as possible, or if more detailed information is needed for severity classification, some items have been modified or newly created.

5 is an example of the explanation window of the item of the computerized first aid activity log of the present invention.

The present invention is configured to display a separate screen for explaining the corresponding contents when clicking on the item title in order to facilitate understanding what the corresponding items of the first aid activity log as shown in FIG.

6 is an example of the information display requested in the computerized emergency log of the present invention.

When entering information about the patient and pressing the OK button to determine the severity, if it is difficult to classify the severity only by the corresponding information, the red border of the information is reflected to reflect the connection as shown in FIG. Indicates. On the other hand, in this case, since the patient's condition is actually good, there may be cases in which the patient information is no longer needed, so the number of times that the severity determination button can be pressed is limited to two times so that the severity can be determined only by the input information.

Improving the efficient operation of the emergency medical system through appropriate transportation for the emergency patient's condition is one of the important goals of the severity classification, the present invention provides a method for selecting a transfer hospital through the severity classification. To this end, referring to the provisions of Article 2-5 Emergency Medical Institutions of Korea's Emergency Medical Law, hospital information was collected in three categories: emergency medical centers, emergency medical institutions, and on-call medical institutions. Since it is only one place, it is considered an emergency medical center.

In the present invention, the distance from the patient occurrence area determined arbitrarily according to the hospital information is obtained, and the result information by the severity classification is composed of the severity and the appropriate treatment time of the patient, so the severity classification of the patient (Immediate / Emergency / Urgency / other ), The appropriate treatment time (immediately within 10 minutes / within 60 minutes / none) is classified based on the distance to the patient based on the hospital information collected based on the average speed of the ambulance 30 km / hr (closest / 5 km / 30 km) All hospitals) and less than semi-urgent severity outcomes are hardly considered an emergency and are therefore classified in other groups.

7 is a sequence diagram showing the relationship between the severity classification and the transfer hospital selection process in the present invention.

The reception management unit 135 fills in the items of the emergency rescue journal according to the condition of the emergency medical personnel according to the patient's condition and inputs the information according to the patient's condition (S100), and the sex and age of the patient input from the reception management unit 135 for severity classification. Information is transmitted to the patient group management unit 155 (S120), the reception management unit 135 transmits the location of the patient to the hospital selection location management unit 160 (S140).

When the emergency medical personnel input the past medical history information of the patient in the past medical history unit 140 (S160), the past medical history unit 140 transmits the past medical history information of the patient to the patient group management unit 155 (S180).

When the emergency rescuer inputs the event situation information to the event situation unit 145 (S200), the event situation unit 145 transmits the event situation information to the patient group management unit 155 (S220).

When the emergency rescuer inputs the observation test information to the observation inspection unit 150 (S240), the observation inspection unit 150 transmits the observation inspection information to the patient group management unit 155 (S260).

Patient group management unit 155 classifies the severity (S280). The severity classification of patients is divided into immediate treatment group (time value is immediate), emergency patient group (time value is within 10 minutes), emergency patient group (time value is within 60 minutes), and other groups.

Hospital selection location management unit 160 receives emergency medical institution information from the regional emergency medical center 200 (S300), and determines the adjacent hospital (S320). That is, the hospital selection location management unit 160 receives information from neighboring hospitals of emergency medical centers and emergency medical institutions and hospitals of internal medicine, surgery, pediatrics, obstetrics and gynecology, and other departments from the emergency medical center 200.

The hospital classification management unit 165 receives the severity classification result from the patient group management unit 155 (S340) and receives adjacent hospital information from the hospital selection position management unit 160 (S360).

Hospital classification management unit 165 allocates the corresponding hospital classification to the patient classification (S380). In other words, the immediate care patient group is assigned the nearest emergency medical institution, the emergency patient group is assigned an emergency medical institution within a radius of 5 km, the emergency patient group is assigned an emergency medical institution within a radius of 30 km, and the other group is assigned to patients in the relevant area. Assign the on-call medical institution. When the average speed of the ambulance is regarded as 30 km / hr, the distance value within 5 km and within 30 km may vary.

In other words, when the emergency medical personnel fill in each item of the first aid journal according to the patient's condition, the reception management unit 135 identifies the patient's sex and age information for the severity classification, and the past medical history unit 140 records the patient's past. Medical history information is grasped, the information corresponding to the patient's state in the event situation unit 145 and observation inspection unit 150 is grasped. The information thus determined is determined in the patient group management unit 155 the severity of the patient.

In addition, the reception management unit 135 obtains the information on the location of the patient and the emergency emergency (ER) hospital information in the regional emergency medical center (200), through which the hospital selection location management (160) based on the patient occurrence location Identify possible adjacent hospitals. Adjacent hospital information and the result of the patient's severity determination are linked through the hospital classification management unit 165 to serve as a transport hospital selection guide according to the patient's severity.

The linkage method was assigned to the immediate care patient group, emergency group, emergency group for emergency medical centers / institutions, and other patients as non-emergency patients. This takes into account the ability for proper diagnosis and treatment in the future when the patient arrives at the transfer hospital.

On the other hand, the immediate treatment patient group (Immerdiate group), emergency group (emergency group) and emergency group (Urgency group) are different in the target time due to the severity classification results. The difference occurs. The immediate treatment group displays the nearest emergency medical center, the emergency group is a 5 km radius of the emergency medical center, and the urgent group is a 30 km radius of the emergency The medical center is displayed. This was converted into distance considering the average speed of 30km / hr in Seoul. Other groups are not significantly related to the target time in emergencies, so the on-call medical institutions are divided into internal medicine, surgery, pediatrics, obstetrics and gynecology, orthopedics, and other departments. do.

In addition, since the hospitals with moderate severity may not be shown by the above process, all emergency medical institutions in the relevant area will appear so that the transportation distance is close and the hospital selection for the patient can be made as possible.

8 is an example of the transfer hospital guide window according to the severity classification results in the present invention.

Through the screen window in FIG. 8, it is possible to know the distance from each transfer hospital and the patient of the transfer hospital.

The present invention is not limited to the above described and illustrated in the drawings, and of course, more modifications and variations are possible to those skilled in the art within the scope of the following claims.

As described above, the present invention provides an emergency medical information system that receives emergency activity log information through a web application, determines the severity classification of the patient, and selects an optimal transport hospital for the patient, based on this. The computerized first aid activity log of the invention provides information to classify the severity while maintaining the marking form of a conventional first aid activity log, and is made easy to use.

Severity classification is an important area of emergency medical care at present, but emergency personnel working at non-hospital sites or medical personnel working at small and medium hospitals do not have sufficient clinical experience or academic knowledge about emergency medical treatment. In many cases, there is a lack of rapid assessment and there are limited testing instruments available in pre-hospital situations and limited physical examinations. In this respect, the occurrence of the event and the symptoms that the patient complains about are easier to acquire than other information, but can be an important basis for the patient's grasp. Not only will it help, but it will also help you approach the disease effectively when the diagnosis is made later in the hospital. In this environment, the following effects can be expected from this study.

First, without having to know the triage system separately. By recording the patient's condition, a triage system can save time and effort in triage.

Secondly, the ambulance is able to function effectively according to the patient's condition away from the role of merely staying in the patient transfer function. If this role is activated, it may contribute to the improvement of the inefficiency and economic efficiency which may be caused by emergency room visits by non-emergency patients.

In addition, in the present invention, when determining the distance to the hospital no matter where the patient occurs, it is possible to easily set up a transfer hospital using a global positioning system (GPS) technology.
