Currently, the number of animals administered in animal hospitals and drugs prescriptions has increased. At the same time, the number of cases of violation of administrative measures due to violations of the Narcotics Control Act has also increased. Therefore, it is necessary to review whether the current status of drug prescriptions, management and supervision systems in animal hospitals are correct and whether there is anything to be supplemented. Although drug handling is managed through NIMS, there are problems such as poor supervision due to the NIMS single system, reporting exceptions that form blind spots for management supervision, and lack of connection between prescriptions and medical departments within the system. In order to overcome these problems, the following improvement plans are proposed. First, reduces the hassle of handling reports and facilitates verification of medical records and prescriptions by strengthening the link between NIMS and animal hospital electronic charts, and strengthens the link between drug handling reports of medical institutions and drug handling reports of animal hospitals to prevent exposure to medical shopping. Second, by introducing a preliminary notification system into the veterinary system, drug misuse is prevented through prior notification in accordance with the criteria for preventing misuse of animal drugs. Third, by modifying the NIMS reporting system by introducing disease classification symbols, the exact cause of the increase in use is identified by preparing drug use data for each disease. Based on these improvements, it is expected that a management system that reflects the actual medical environment of animal hospitals will be established and drug abuse will be prevented based on guidelines.
