Evaluating patient knowledge and use of medication disposal in a Chinatown community pharmacy

Abstract

BackgroundDrug take-back programs (TBPs) provide the opportunity to safely dispose of unused or expired medications (UEMs), potentially reducing the risk of environmental harm and morbidity. Data on patient perceptions and participation are limited, especially in underserved Asian populations. ObjectiveThis study aimed to evaluate medication disposal perceptions and behaviors through a free mail-in medication disposal program among patients in a Chinatown community pharmacy. MethodsAn institutional review board–approved Web-based survey was developed in English and Mandarin. Student pharmacists tabled at a Chinatown community pharmacy in Boston, Massachusetts. The patients were educated about safe medication disposal practices and invited to take the anonymous survey assessing medication disposal needs, practices, and beliefs accessed in person by using a quick response code. On survey completion, the patients were offered a disposal envelope. Envelope tracking numbers were used to evaluate medication disposal over a 9-month follow-up period. ResultsSixty-two patients of Asian descent completed the survey, and 42 (67.7%) accepted an envelope. Forty-seven patients (75.8%) reported having access to UEMs. More than half indicated that TBPs were important to alleviate the risk of medication and environmental consequences despite low previous use (6.5%). Most patients felt more aware of TBPs (72.6%), an increased sense of the importance of TBPs (74.2%), and intent to participate in TBPs (69.4%), including using the envelope (75.8%). Three (4.8%) patients disposed of medications using the study-provided envelope during the 9-month follow-up. ConclusionPatient education about TBPs and their importance may be effective in increasing TBP awareness in a population with low TBP use. Free disposal envelopes did not seem to be highly used within 9 months of receipt despite interest and access to UEMs. Future research should continue offering programs at no charge, evaluating barriers to free TBP use, and implementing follow-up procedures to increase envelope use.
