Class of 2013 Abstract / Specific Aims: The purpose of the study is to describe the reasons for medication disposals at Take-Back-Rx events and make inferences regarding medication adherence. Methods: Participants at Take-Back-Rx were invited to complete a survey that collected information on the participants current medical conditions, associated medications, unwanted medications, and demographic information. Main Results: The majority of participants were non-Hispanic White (89.2%) on Medicare (87.8%) with at least some college education (72.1%). The mean number of reasons listed for disposal was 2.25 and the majority of medications were expired (70%) or the dose/agent changed (47%). Conclusion: This study effectively described the reasons for medication disposals at Take-Back Rx events, but applicability to further patient populations may be limited due to shortcomings of the instrument.
