Description

Embodiments of the present invention relates to a hospital information system and program.

In order to prevent the occurrence of medical errors such as misidentification of patients and medication errors in medical institutions, authentication technology using bar codes is used. For example, when administering a drug to a patient based on a prescription instruction to instruct a drug to be prescribed to the patient by a doctor, the barcode printed on the wristband worn on the patient and the drug attached to the container of the drug The barcode printed on the label is read by the mobile terminal. Thereby, it is determined whether or not the drug based on the prescription instruction is correctly administered to the patient.

On the other hand, the workload of the medical staff such as issuing the barcode, creating the wristband and the label, distributing the wristband, and attaching the label increases. In addition, errors such as a wristband distribution error, a label sticking error, and a barcode reading error occur. This increases the risk of medical malpractice such as patient misidentification and medication error.

In step S11, the processing circuit 46 transfers the input transfer patient image ImgP and transfer drug image ImgM to the medical information management apparatus 3 by using the image confirmation operation as a trigger.

In step S12, the processing circuit 36 determines the prescription instruction of the designated execution number “0003” based on the comparison between the transfer patient image ImgP and the related patient image and the comparison between the transfer drug image ImgM and the related drug image. , The transfer patient image ImgP and the transfer drug image ImgM are determined to be correct or not. In order to determine whether or not the combination is correct, the processing circuit 36 executes the comparison process of the patient images in step S12a and the comparison process of the drug images in step S12b.

First, the patient image comparison processing in step S12a will be described.

FIG. 10 is a diagram showing a patient image master stored in the database 35 shown in FIG. The patient image master illustrated in FIG. 10 associates a patient ID with a feature amount of at least one patient image for each of a plurality of patient images. Here, in step S5, the medical staff specifies the prescription instruction with the implementation number “0003” as the prescription instruction to be executed. Therefore, the processing circuit 36 reads the related patient image ImgP-1 associated with the patient ID “P-1” included in the prescription instruction of the designated execution number “0003” from the patient image master of the database 35. FIG. 11 is a diagram showing a related patient image ImgP-1 read out from the patient image master of the database 35 shown in FIG. The processing circuit 36 compares the characteristic amount of the transferred patient image ImgP shown in FIG. 5 with the characteristic amount of the related patient image ImgP-1 shown in FIG. 11. The processing circuit 36 determines whether or not the matching rate between the feature amount of the transferred patient image ImgP and the feature amount of the related patient image ImgP-1 is equal to or higher than a predetermined threshold value based on the comparison. For example, the processing circuit 36 calculates the matching rate for each of the contour of the patient's face, the skin color of the patient, and the distance between the nose and eyes of the patient regarding the patient image. The processing circuit 36 determines whether or not the matching rates for the patient images are all equal to or greater than a predetermined threshold value.

If all the matching rates for the patient images are equal to or higher than the predetermined threshold, the processing circuit 36 determines that the transferred patient image ImgP and the related patient image ImgP-1 match. If at least one of the matching rates for the patient images is less than the predetermined threshold, the processing circuit 36 determines that the transferred patient image ImgP and the related patient image ImgP-1 do not match.
