DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine search system for verifying the presence or absence of interaction between medicines when performing a prescription audit in a prescription input system or a premium claim system used in a medical field.

[0002]

2. Description of the Related Art In the past, there has been a social problem caused by a fatal medical accident caused by serious side effects due to the interaction of pharmaceuticals. For this reason, a system for verifying the presence or absence of interaction between drugs is required.

[0003] By the way, the latest information on drugs, including information on interactions, is supplied to the world from pharmaceutical companies as drug attachments. At present, the description of the interactions in the pharmaceutical package insert is unique to each pharmaceutical company. Further, the interaction in which the drug that expresses the interaction is expressed in a 1: n relationship is not standardized.

[0004] There are roughly two methods for checking the interaction of drugs. One is to determine the textual description of the interaction by comparing the text with each prescription audit, and the second is to prepare a pair of drugs that may cause an interaction in advance. .
In the latter method, it is an issue how to reflect the latest information, and there is a social demand for promptly reflecting the interaction information of a drug in the data for interaction verification.

[0005] A system for verifying drug interactions in computer software used in the medical field includes:
For a drug to be verified, a drug in which a drug that may interact with the drug is registered in advance as a pair based on the drug information as described above has been used.

[0006]

In the medical practice, it takes a great deal of labor for a medical worker to predict which medicines will interact with each other and to perform the above-mentioned registration work manually. is necessary. Also, even once registered, new drug information is generated every day, and even more labor is required to keep it up to date. For this reason, it has been difficult to frequently update the data following pharmaceutical information that changes daily. Also, when trying to search for textual information on drug interactions by drug name, applying conventional techniques requires that words in the text be registered in advance as keywords. However, this also requires a large amount of work and is not feasible.

[0007] An object of the present invention is to solve such a problem and to verify the presence or absence of interaction between drugs with good productivity.

[0008]

According to the drug interaction verification method of the present invention, when verifying the presence or absence of interaction between drugs, interaction verification data is created in advance based on textual information on drug interactions. The textual information of drug interactions is composed of a set of textual information of drug potentials that can produce interactions for each drug name, and the information for each drug is the drug name And a body part consisting of the interaction information on the drug in the heading, and the paragraph position in the sentence structure in the body part corresponding to the severity of the interaction is used. As the source drug name,
Furthermore, a drug name that is different from the search source drug name but indicates the same drug is used as the search source synonymous drug name, and a search is performed on the text part of the textual information on drug interactions, and the search source drug name or the search source synonymous When a drug name was searched and extracted from the body part, the drug name in the heading part corresponding to the body part was determined to be the name of the partner drug that could have an interaction with the drug of the source drug name, and further searched and extracted After replacing the paragraph position in the main text with the severity rank that indicates the severity of the interaction, a record of the set of the source drug name, the partner drug name, and the severity rank is recorded. It is characterized by data for operation verification.

Here, as the search source synonymous drug name, a drug class name, an organic chemical class name, or the like representing the drug of the search source drug name is used.

In the search of the present invention, a sentence in which an arbitrary word (a) exists with respect to an arbitrary set of sentences (a) can be replaced with an arbitrary word (a) without preparing for keyword registration. As a sentence in which the word (a) exists, a method of rapidly searching a sentence set (a) and extracting a sentence containing an arbitrary word (a) can be used. In other words, by performing a high-speed search for any drug name or another word meaning a drug in the text on drug interactions, any drug can generate an interaction from a vast set of sentences It can be extracted as a drug that may be present.

In the present invention, such a search is mechanically repeated for the entire sentence information related to the interaction to create data for interaction verification. In addition, it is preferable to target as many drug names as possible as search source drug names. Since the interaction verification data of the present invention thus obtained is provided with necessary data in a simple data structure, it is possible to verify the presence or absence of interaction between drugs with high productivity. it can. Further, the data for interaction verification created here can be used as it is as basic data in a conventional interaction verification system.

In the present invention, it is preferable that the interaction verification data is a set of a search source drug name, a partner drug name, a severity rank, and a search source synonymous drug name. Further, as the severity rank recorded in the interaction verification data, it is preferable to use the name of the paragraph name previously assigned to each paragraph in the body part. This increases the size of the data, but can help the verifier understand the content during drug interaction verification.

Alternatively, in the present invention, the name of the drug to be recorded in the interaction verification data is preferably recorded as a code indicating the drug.
This allows the data size to be smaller than when the name is recorded as it is, and in some cases, such as prescriptions, the drug is represented by a code. In such a case, the speed at which the data is referred during verification is increased. Can also be improved.

In the present invention, at the stage of prescribing a drug by a doctor and at the stage of dispensing based on a prescription by a pharmacist, the combination of drugs on the prescription is referred to by referring to the interaction verification data of the present invention. It is preferable to verify the possibility that an interaction will occur due to the application of the formulation. That is, the productivity of the verification work can be improved by using the interaction verification data of the present invention.

[0015]

EXAMPLE As an example of the present invention, interaction verification data was created based on the "medicine information database" information provided by the Medical Information System Development Center.

[0016] The "pharmaceutical information database" information
This corresponds to textual information on drug interaction in the present invention. In other words, the “medicine information database” information is configured as a set of information of medicines that have a possibility of developing an interaction in a text format for each medicine name. In addition, information for each drug consists of a heading part consisting of the drug name and a text part consisting of interaction information on the drug under the heading. In the text part, the position of the paragraph in the sentence structure indicates the severity of the interaction. It corresponds to.

The obtained data for interaction verification is
Used when auditing the interaction of prescriptions in the prescription input system or the insurance claim system, and used to discover and clearly indicate to the end user the possible combinations of interactions between the prescribed drugs, The productivity of the interaction verification work was improved.

Specifically, at the time of checking the prescription, for the combination of drugs on the prescription, an operation of referring to the interaction verification data prepared in advance by the code of the drug was performed. Here, if there is a corresponding drug, it means that the prescription may cause some interaction. Furthermore, by providing descriptive text in the main text regarding the interaction of the relevant drug, the final judgment of the human being could be obtained, and this could be used to change the prescription and provide guidance on medication.

The timing of creating the data for interaction verification is performed every time the “pharmaceutical information database” information is newly provided from the Medical Information System Development Center. Provided to the site.

[0020]

As described in detail above, the present invention realizes the rapid creation of drug interaction verification support data at any time by using the latest textual information on drug interaction, and enables pharmaceutical companies Will be able to promptly reflect the latest information on the package insert issued by the company in the data for interaction verification. Further, in the present invention, the time for interaction verification can be reduced as compared with the conventional method. This can be useful information in medical practice where a quick prescription check is required.

As described above, when a doctor determines an interaction that may occur in a prescription he describes in accordance with a medical treatment, or when a pharmacist dispenses a prescription based on the prescription, only a judgment relying on human memory. Instead, by receiving the help of verification by a computer system, it is possible to assist humans in acquiring the latest information and to contribute to prevent accidents due to interactions associated with drug administration.
