TECHNICAL FIELD OF THE INVENTION
The present invention relates to a medical information management system and a management method for managing medical information.
[0002]
[Prior art]
Some conventional medical information management systems aim to prevent medical mistakes by managing medical information using barcodes. For example, in a system described in Japanese Patent Application Laid-Open No. 2001-155098, “Medical Information Management System”, a barcode indicating the content of a prescription is printed on a prescription, and a barcode indicating the name of the drug and the amount of the drug is attached to the drug. In addition, doctors, nurses, and patients carry barcodes indicating their names, so that information on prescriptions and medications can be managed with a computer, and if a medicine different from the one written on the prescription is used. Can alert it.
[0003]
Another conventional medical information management system uses an RFID (Radio Frequency Identification) in addition to a barcode. An RFID is an IC used for identifying objects in a non-contact manner, and is also called an RF tag, an IC tag, or the like. For example, Japanese Patent Application Laid-Open No. 2002-132962, "Hospital Medical Information System for Preventing Patient Misidentification" describes an example of a system similar to the above, which uses an RFID in addition to a barcode.
[0004]
Further, there is another conventional system in which a history of medical information can be written in an RFID or an IC card in which personal information of a patient is written. Japanese Patent Application Laid-Open No. 2002-109070 entitled "Medical Supplies, Medical Information Processing Method, Drug Administration Confirmation Device, Drug Administration Confirmation Method, and Printing Apparatus and Printing Method" discloses that an RFID is attached to a patient as a wristband, Describes a system in which, in addition to personal information of a patient, information indicating a medication history and an examination history can be written at any time. Japanese Patent Application Laid-Open No. 2000-342638 discloses a system in which an IC card provided for a patient or his / her bet can record a medical history in addition to an identification code of the patient.
[0005]
In another conventional system, an IC card carried by a patient can record, in addition to identification information of the patient, medical information on prescription, treatment, and the like for the patient. Japanese Patent Application Laid-Open No. 2002-157341 discloses a "medical accident prevention method", in which patient information including a patient name, a patient ID number, a medical history, and the like are recorded on a patient IC card, and prescriptions, treatments, and the like specified by a doctor are indicated. A system is described that enables the storage of therapy information.
[0006]
[Problems to be solved by the invention]

Things. In these systems, a doctor inputs instruction information such as prescription and treatment using a computer terminal or the like, records the input information on a computer, an IC card, or the like, and prepares for treatment such as medication based on the recorded information. And implementation. In such a system, for example, as described in the above-mentioned Japanese Patent Application Laid-Open No. 2000-342638, by combining with a system of an electronic medical record, it is possible to input details of instructions by a doctor in detail and accurately. .
[0007]
By the way, regardless of the presence or absence of digitization, a medical record (medical record) records in detail information such as a treatment method including prescription and treatment, a date of medical treatment, and the like. Records on medical records are usually made prior to treatment. However, the medical record may be recorded after a change or addition of treatment is made based on oral or telephone instructions to other doctors and nurses. In other words, there may be a case where the instruction content on the medical record input and recorded by the doctor is temporarily different from the actual treatment content. In such a case, in a conventional system using an electronic medical record, it is necessary to exceptionally omit part or all of the computer processing for identification and collation using recording means such as a barcode, RFID, and IC card. It is possible to do.
[0008]
The present invention has been made in consideration of the above circumstances, is intended to prevent careless mistakes in medical treatment, and can flexibly cope with the addition or change of instruction contents related to medical treatment, Furthermore, since a patient has a history of medical instruction contents and medical treatment contents, it is an object of the present invention to provide a medical information management system and a management method that can prevent falsification of records by doctors, nurses, and the like.

[0019]
Next, an operation example of the medical information management system shown in FIG. 1 will be described with reference to FIGS. FIG. 3 is a sequence diagram showing, in a time series, an operation example when a doctor examines a patient and issues a treatment instruction in a consultation room or the like. Here, the flow of processing at the time of re-examination for a certain patient will be described as an example.
[0020]
When the doctor operates the doctor terminal 3 to perform the authentication process (step 101 in FIG. 3), the input authentication information such as the doctor's personal identification number and password is transmitted to the information management server 1 and the information management server 1 The result is sent to the doctor's terminal 3. The input of the personal identification number is performed by bringing the reader / writer 7 close to the vicinity of the ID card 21 of the doctor. Here, if the authentication result is acceptable, the following processing can be executed.
[0021]
The doctor terminal 3 displays an operation to be performed next (in this case, an instruction to read the data of the patient RFID 31a). When the doctor brings the reader / writer 7 closer to the patient wristband 31 in accordance with the display, The patient's personal information (patient ID, chart number, allergy information in FIG. 2) recorded in the patient RFID 31a is transmitted from the patient RFID 31a to the doctor terminal 3 (steps 102 to 103). The doctor's terminal 3 transfers the acquired information to the information management server 1 (step 104), and subsequently performs a process of acquiring information on the treatment and medication from the patient's RFID 31a, and additionally input information about them. (Step 105). Upon receiving the transmission request signal for the treatment / medication and their additional information, the patient RFID 31a transmits the requested information (step 106). The doctor terminal 3 transfers the acquired information to the information management server 1 (Step 107).
[0022]
Next, the information management server 1 transmits the information of the medical record (electronic medical record) of the patient (step 108), and the contents of the medical record are displayed on the doctor terminal 3 (step 109). At this time, information on the medical record that has been recorded so far and history information on the latest treatment and medication that have not yet been recorded in the medical record are displayed. As the latest history information (unconfirmed information), the history information on the treatment and medication that occurred between the time of the previous medical record recording and this operation is based on the instructions already recorded in the medical record, The information is displayed in a distinguished manner from those that have not yet been recorded, such as those spoken or given by telephone or the like. Here, when the doctor performs an operation of inputting information on the current treatment instruction (treatment and medication instruction) and other supplementary information, and further performs a finalizing operation on undetermined information (step 110), the information management server 1 executes A medical record update process (input of new information and confirmation process of unconfirmed information) is performed (step 111).
[0023]
Next, the information management server 1 converts a part or all of the information required for the treatment instruction (treatment and medication instruction) information into a recording format for the patient RFID 31a, and then converts the information into instruction information. Is transmitted to the doctor terminal 3 (step 112). The doctor terminal 3 transfers the received information to the patient RFID 31a (step 113), and the instruction information is recorded on the patient RFID 31a (step 114).
[0024]
Next, with reference to FIG. 4, an operation example when preparing a medicine or a medical device used for the treatment of the patient in a treatment room, a treatment preparation room, or the like will be described. First, when a certain nurse A operates the nurse terminal 4 to perform an authentication process (step 201 in FIG. 4), the information of the personal identification number of the nurse A inputted using the ID card 22 and the nursing Authentication information including the password input at the professional terminal 4 is transmitted to the information management server 1. Then, authentication is confirmed in the information management server 1, and the result is sent back to the nurse terminal 4. Here, if the authentication result is acceptable, the following processing can be executed.
[0025]
The nurse terminal 4 displays a display of an operation to be performed next (in this case, a display instructing to read data of the patient RFID 31a), and the nurse A places the reader / writer 8 on the patient wristband 31 in accordance with the display. When approached, the patient's personal information (patient ID, chart number, allergy information, etc. in FIG. 2) recorded in the patient RFID 31a is transmitted from the patient RFID 31a to the nurse terminal 4 (step 202 to step). 203). The nurse terminal 4 transfers the acquired information to the information management server 1 (step 204), and subsequently performs a process of acquiring instruction information regarding treatment and medication from the patient RFID 31a (step 205). Upon receiving the transmission request signal for the treatment / medication instruction information, the patient RFID 31a transmits the requested information (step 206).
[0026]
Next, the nurse terminal 4 performs a process of acquiring treatment instruction information from the information management server 1 (step 207). Here, the treatment instruction information is information indicating the contents of a treatment (treatment and medication) instruction by a doctor based on the recorded contents of the latest medical record. When the information management server 1 transmits the treatment instruction information (step 208), the nurse terminal 4 receives and displays the information (step 209).
[0027]
Next, based on the treatment instruction information displayed on the nurse terminal 4 (or based on a description of a document printed in a predetermined format), the nurse A uses a medical device (for example, a thermometer, List of blood pressure monitors, blood flow meters, tonometers, electrocardiographs, clinical chemistry test equipment, blood test equipment, syringes, tubes and catheters, blood collection and transfusion equipment, infusion equipment, suturing equipment, etc.) and administration A list showing the names and quantities of medicines to be entered is input to the nurse terminal 4 as treatment preparation information (step 210). In addition, even if the information is not included in the treatment instruction information displayed on the nurse's terminal 4, the treatment or administration of the treatment or medication instructed, for example, orally by a doctor or by using a telephone or a handwritten document is performed. If there are instructions, information on the medical devices and medicines to be used for them is also input into the nurse terminal 4 as treatment preparation information at the same time (step 210). However, when there is no need to particularly modify the treatment instruction information acquired in step 207, the processing in steps 210 to 217 can be omitted. That is, for example, the presence or absence of a correction is confirmed at the time of the display process in step 209, and if there is no need for correction, after the medicine and the medical device are actually prepared based on the treatment instruction information, It is also possible to change the flow of the processing so as to resume from the processing.
[0028]
The nurse terminal 4 collates the treatment preparation information input in step 210 with the instruction information acquired from the patient RFID 31a in step 205, and checks whether there is any contradiction (step 211). For example, if there is a verbal instruction after the final update of the medical record data by the doctor and the treatment preparation information input in step 210 includes a new medicine not recorded in the patient RFID 31a, The terminal 4 determines that the collation has not been performed (“no” in step 212). In this case, the nurse terminal 4 determines whether or not the operating nurse A is registered as being able to modify the information in the patient RFID 31a (step 213). Based on the treatment preparation information input in step 210, instruction information to be additionally recorded in the patient RFID 31a is created as additional instruction information (step 215). Then, the nurse terminal 4 transmits the additional instruction information to the patient RFID 31a (step 216), and the additional instruction information is recorded on the patient RFID 31a (step 217).
[0029]
On the other hand, if it is determined in step 212 that the collation has not been performed, and furthermore, if it is determined in step 213 that the operating nurse A cannot correct the information in the patient RFID 31a, this is displayed on a screen in step 214, A notification is made by sound output (step 214), and a display requesting the input of treatment preparation information is performed again (step 210).
[0030]
If the collation is determined in step 212, or the additional instruction information is recorded on the patient RFID 31a in steps 216 to 217, the nurse A is shown in the list input as the treatment preparation information in step 210. You will actually prepare medical equipment and medicines. Here, in the case where the medicine to be prepared is, for example, a medicine bottle 41 shown in FIG. 1 which is subdivided into a predetermined unit amount, there is no need to rewrite the recorded contents of the RFID attached to the medicine in advance. . However, for example, when a plurality of chemicals are mixed and filled into the drip bag 42 as shown in FIG. 1, it is necessary to rewrite the recorded content of the RFID 42a so as to be compatible with the actual content. This rewriting process is desirably executable by the nurse terminal 4. However, it may be executed by another device. Then, when the necessary medical devices and medicines are prepared, the prepared items are compared with the treatment preparation information using the nurse terminal 4.
[0031]
The reader / writer 8 sequentially (or at once) approaches the prepared medical device or medicine and reads the recorded contents of the RFID attached to the medical device or medicine, and reads the read information and the treatment preparation information (or If the treatment instruction information does not need to be corrected, the collation with the treatment instruction information is performed (step 218). If there is no problem in the collation result, for example, the fact is displayed, and then the collation processing ends (step 219). On the other hand, if there is an inconsistency in the collation result, this is reported (step 220), and the collation processing is performed again (step 218).
[0032]
Next, with reference to FIG. 5, an example of an operation when an actual treatment or medication is performed on the patient in a treatment room, a hospital room, or the like will be described. First, when a certain nurse B operates the reader / writer 5 to perform an authentication process (step 301 in FIG. 5), the personal identification number of the nurse B input using the ID card 23 in the reader / writer 5 is obtained. Authentication is performed to determine whether or not the information matches the information registered in advance. Here, if the authentication result is acceptable, the following processing can be executed.
[0033]
A display for selecting an operation to be performed next is displayed on the liquid crystal screen of the reader / writer 5. When the nurse B selects the collation processing of medicine and medical equipment, a display for instructing reading of data of the patient RFID 31a is displayed. Is made. When the nurse B brings the reader / writer 5 close to the wristband 31 of the patient in accordance therewith, the patient's personal information (the patient ID, the chart number, allergy information, etc. in FIG. 2) recorded in the patient's RFID 31a is read. Is transmitted to the reader / writer 5 (steps 302 to 303). The reader / writer 5 subsequently performs a process of acquiring instruction information regarding treatment and medication from the patient RFID 31a (steps 304 to 305). Further, the reader / writer 5 performs a process of acquiring additional instruction information regarding treatment and medication from the patient RFID 31a (steps 306 to 307). Here, the instruction information corresponds to an instruction already recorded in the medical record, and the additional instruction information corresponds to an instruction not yet recorded in the medical record.
[0034]
By bringing the reader / writer 5 closer to the prepared medical device or medicine one by one (or all at once), the reader / writer 5 reads and reads the recorded content of the RFID attached to the medical device or medicine. The collated information is compared with the instruction information and the additional instruction information (step 308). If there is no problem in the collation result (step 309), that fact is displayed (step 310). On the other hand, if there is a contradiction in the collation result, this is reported (step 311), and the collation processing is performed again (step 308).
[0035]
Next, when an operation (first input operation) for confirming that the medicine and the medical device have been used is performed by the nurse B (step 312), the reader / writer 5 sends the used information to the patient RFID 31a. The information is transmitted (step 313), and the used information is recorded in the patient RFID 31a for each medicine and each medical device (step 314).
[0036]
When an operation (second input operation) for confirming the disposal of the used medicines and medical devices used by the nurse B is performed (step 315), the reader / writer 5 sends the disposal confirmation information to each The medicine and each medical device are transmitted to the information management server 1 (step 316), and the information is recorded in the database 2 by the information management server 1 (step 317). It is preferable because inventory management of medicines and medical devices can be performed using this discard information.
[0037]
In the above operation example, in each of the stage of preparing the medicine or the medical device and the stage of actually using the medicine or the medical device, the contents of the preparation or use and the correspondence recorded in the storage means (RFID 31a) of the patient Since the matching with the information to be performed is performed, the possibility of occurrence of careless mistake can be further reduced. In addition, since information on the used medicines and medical devices is recorded in the storage means (RFID 31a) of the patient, by reading the information recorded in the storage means (RFID 31a), it is possible to accurately confirm the actual treatment content. Can be. Therefore, it is possible to prevent a problem that the information is lost when the treatment content is changed or corrected in the middle. In addition, it is conceivable that the correction of the data to be verified when performing the actual treatment or medication may not be appropriate in terms of time or place. However, in the preparation stage, the correction processing is performed, and the verification processing is further performed. As a result, the accuracy can be further improved, and the possibility of occurrence of a careless mistake in the correction processing can be reduced.
[0038]
Note that the above embodiment is an example of the embodiment of the present invention. For example, the number of terminals and reader / writers is increased, and the information recorded on the RFID 31a is used at the time of examination or surgery. It is possible to appropriately make changes such as enabling confirmation and treatment instruction confirmation. The present system may be combined with an electronic medical record system, or may be configured as a system that does not use an electronic medical record system. If the electronic medical record system is not used, instructions from doctors to nurses etc. can be made using the medical record of the document, or documents using similar instructions in other forms can be used. it can. Further, the program used in the present embodiment can be distributed via a computer-readable recording medium or a communication line.
[0039]
【The invention's effect】
According to the present invention, at each stage of preparing a medicine or medical device and using an actually prepared medicine or medical device, information recorded in the first storage means carried by the patient, Since the collation processing is performed with the identification information attached to the medicine or the medical device, careless mistakes in medical treatment can be prevented, and the data can be more reliably recorded in the first storage means, for example, in the preparation stage. Since the information can be corrected, it is possible to flexibly cope with the addition or change of the medical instruction content.
