Effectiveness of the kakaritsuke-yakuzaishi (family pharmacist) system for underage individuals in Japan: a cohort study using a health insurance claims database

This study demonstrated that the family pharmacist system improved TDDI prevention among underage individuals. However, its effectiveness was consistent regardless of the characteristics related to the utilization of the family pharmacist system, indicating that the trend of positively applying the system to those with these characteristics was not supported. The operation of the system may be reconsidered for the efficient allocation of medical resources.
