Objective: To examine the effect of pharmacists’ visits to homebound patients on the elimination of unused drugs.Method: We conducted a survey with pharmacies throughout Japan that provided home-visit service, asking them questions regarding their work with up to five patients (the survey period was from January 15 through the end of February, 2013). Main survey questions were: (1) whether they managed unused drugs since the start of their home-visit, and (2) how they managed the unused drugs. For (2), we conducted case studies by asking the pharmacists to choose the case that impressed them most and describe the unused drugs involved, actions taken, and the results.Results: Data on 5,447 patients were collected from 1,890 pharmacies throughout Japan (collection rate: 56.9%). Pharmacists managed unused drugs from 2,484 patients (45.6%). 1,746 patients (3,590 cases) were qualified for analysis. In 2,332 cases (65.0%), pharmacist intervention eliminated the incidences of unused drugs. In 782 cases (21.8%), unused drugs were discarded, while the number of drug administration days was adjusted in 2,623 cases (73.1%). In 21 cases (0.6%), drugs were both discarded and had the number of days adjusted. There were others for 164 cases (4.5%). The total price of the eliminated unused drugs was approximately 6,920,000 yen (4,000 yen/person). Illnesses that benefited most from the elimination of unused drugs were chronic respiratory failure (16,306 yen/person), and Parkinson’s disease (4,803 yen/person).Conclusion: We confirmed the economic effect of eliminating unused drugs by pharmacists’ home visits.
