BACKGROUND: No studies in Japan have examined whether dispensing by family pharmacists, who are incentivized by reimbursement to provide continuous and exclusive medication management, results in prescription changes. Our primary objective was to identify the variables affecting prescription changes, particularly to investigate dispensing by family pharmacists as a possible factor.METHODS: We identified 333,503 records of pharmacy claims data from patients aged 65 years or older who received medication instructions at outpatient pharmacies at Tsukuba, a medium-sized city near Tokyo, between April 2018 and March 2019. We extracted data on dispensing by family pharmacists, number of medicines, patient sex, patient age, and pharmacy category. A multilevel modified Poisson regression analysis was performed to analyze the correlation between dispensing by family pharmacists and pharmacist-initiated prescription change.RESULTS: Dispensing by family pharmacists was 1.37 times more likely to involve a record of prescription change than dispensing by non-family pharmacists. Older age, female sex, polypharmacy, and small-scale pharmacies were also found to be factors.CONCLUSION: This study indicated that dispensing by family pharmacists was a potential factor for pharmacist-initiated prescription changes that may prevent excessive medication and limit pharmacological interactions. Since the likelihood of inappropriate prescriptions being issued varies from hospital to hospital, subsequent studies should take into account the quality of each institution.
