Objective : Recently, a directive that all pharmacies should have a family pharmacist by 2025 was announced. However, this directive has not been clearly communicated to patients. The purpose of this study was to examine the effect of patient information handouts on the number of patients who use the new family pharmacist system, using the evaluation index of family pharmacies (Key Performance Indicator [KPI]). Methods : We created and distributed patient handouts about family pharmacists. The number of new family pharmacists, the number of consultations, and the consultation content from June-August 2021 (pre-distribution period) and September-November 2021 (distribution period) were examined to compare the KPI group and non-KPI group. A cutoff score of the KPI index was used to determine compliant vs. non-compliant. Results : The median (interquartile range) number of new patients in the KPI group (7 pharmacies) increased from 0 (0.0, 1.5) in the pre-distribution period to 4 (2.5, 10.5) in the distribution period (P＝0.019). In the non-KPI group (4 pharmacies) it was 0 (0.0, 0.0) both before and after distribution. The number of consultations about unused prescribed medications and health increased (P＝0.031 and 0.047, respectively) in the KPI group during the distribution period, with no change in the non-KPI group. Conclusion : The use of handouts led to an increase in users of the family pharmacist system in the KPI group. The use of handouts at KPI pharmacies will help patients understand the pharmacist profession and the benefits of the family pharmacist system.
