Assessing the prevalence of unused medicines at home and associated factors: a community-based cross-sectional study

Abstract Background Prescriptions come with extensive instructions on taking medicines but provide little information about the burden of unused medicines. This issue centers around the vast quantities of unused medications accumulated in households. The study aimed to assess the prevalence of unused medicines and associated factors in Gondar City. Method The study was conducted through a community-based cross-sectional survey in Gondar City from July 30 to August 30, 2023. The data was collected using the Kobo toolbox, exported into an Excel sheet, and then analyzed using SPSS version 27 software. Both multivariate and bivariate binary logistic regressions were performed in the data analysis. A p-value of 0.05 with a 95% confidence interval was used to determine statistical significance. Result The study interviewed 786 participants, with a 92.8% response rate. 55% of the 786 households surveyed kept unused medications at home, most commonly antibiotics (37%), antipyretics (17.6%), and analgesics (15%). Factors associated with having unused medicines at home included not receiving medication information (AOR = 2.327, 95% CI: 1.535, 3.527), having a chronic disease (AOR = 5.897, 95% CI: 3.667, 9.484), having health insurance coverage (AOR = 1.456, 95% CI: 1.036, 2.047), self-medicating with NSAIDs (AOR = 2.018, 95% CI: 1.396, 2.919), and poor disposal practices (AOR = 3.613, 95% CI: 2.546, 5.127). Conclusion The study found a considerable high prevalence of unused medications in Gondar City due to factors like lack of medication education, chronic conditions, insurance coverage, self-medication, and poor disposal practices. To address this, public education programs and safe disposal guidelines should be implemented to promote safer practices.
