Electronic monitoring-based pharmacist-delivered counseling enhance adherence among Japanese COPD patients
METHODS: We conducted the pharmacy-based retrospective cohort study using EMPC database. We extracted eligible 178 patients (72.6±11.8 year old; 145 male, 33 female) from February to November in 2011, who had been prescribed Spiriva for the first time. We divided patients into two groups: the interventional (INT) group whose patients received EMPC continuously regarding Spiriva at each pharmacy visit, and the control (CNT) group whose patients received only conventional pharmacists counseling. Patients were defined as dropout cases when electronic monitoring discontinued for 2 months or more from the last pharmacy visit. EMPC intervention included standardized documentation templates, pharmacists’ education in advance. The survival analysis (Kaplan-Meier methods) and the Cox proportional hazards model which adjusted patients’ profiles (age, sex) were used.
RESULTS: The median follow-up were 95 months (range: 61 to 163) in INT group, and 30 months (range: 20 to 74) in CNT group respectively. (logrank test p=0.0031, Wilcoxon test p=0.0025) INT group showed significantly lower risk than CNT group, adjusted by age and sex (Hazard Ratio (HR): 0.59; 95% Confidence Interval (CI): 0.41-0.85) over the entire follow-up period.
CONCLUSIONS: EMPC database has potential in pharmacoepidemiological research area. Although further studies are needed, our results suggested that EMPC in pharmacy might contribute to improving medication adherence in COPD patients.
