Description

The embodiments disclosed herein relate to medical information processing devices. In recent years, the aging population has led to an increase in patients with multimorbidity (a condition involving multiple co-existing diseases). In multimorbidity, multiple medications are used in combination, which can lead to side effects not present when using each medication individually, or create additional risks as a result of the treatment itself. It is known that these combined factors can easily increase the patient's risk and burden. Traditionally, techniques have been proposed to detect when symptoms no longer conform to the disease definition due to drug side effects, based on the relationship between disease symptoms and drug side effects. For example, symptoms that should appear in a particular disease may not be present due to drug side effects. However, with conventional technology, it was difficult for users such as doctors to understand the relationships between multiple diseases and multiple treatments, and it was not easy to grasp the risks that are heightened by multiple factors.

The following describes an embodiment of the medical information processing device with reference to the drawings. Figure 1 shows an example configuration of a medical information processing system according to an embodiment. As shown in Figure 1, the medical information processing system 1 includes a patient data DB (Database) 10, a disease data DB 20, a treatment data DB 30, a surrounding environment data DB 40, and a medical information processing device 100. Here, the patient data database (DB) 10, disease data database (DB) 20, treatment data database (DB) 30, surrounding environment data database (DB) 40, and medical information processing device (EDP) 100 are connected to each other via a network N, such as an in-hospital LAN, located within a medical facility such as a hospital. Note that the number of each device is not limited to the number shown in Figure 1. The patient data database 10 is a database that stores data about patients. Specifically, the patient data database 10 holds the patient data table 11. The patient data table 11 stores patient data, consisting of information such as name, disease name, treatment method, severity, dependency, treatment priority score, hobbies and preferences, surrounding environment, and past illnesses, associated with a patient ID that identifies the patient. Each patient's data is registered in the patient data table 11, for example, via a medical information processing device 100 or a terminal device installed in a medical facility such as a hospital. Alternatively, patient data may be registered based on medical information such as electronic medical records. Figure 2 shows an example of the data structure of the patient data table 11. As shown in Figure 2, the patient data table 11 stores patient IDs in association with patient data. For example, Figure 2 shows the patient data for patients
