A cross-sectional survey to assess the drug disposal practices of unused and expired medicines among lay public visiting a tertiary care hospital in an urban metropolis

Abstract

Objectives: A cross-sectional survey was conducted to evaluate the knowledge, awareness and practice among the lay public regarding storage and disposal of unused and expired medicines. Materials and Methods: This was an observational, cross-sectional, single-centre and questionnaire-based survey. After obtaining Institutional Ethics Committee approval, the study was conducted using a pre-validated structured questionnaire distributed among the lay public visiting a tertiary care hospital located in an urban metropolitan city. Results: Four hundred of 720 individuals visiting the tertiary care hospital participated in the survey. The results revealed that 75% had never referred to any sources to get the correct information about the proper and safe disposal of medicines and had no knowledge regarding the same. About 12.75% of study participants reported that they were educated regarding the disposal of medicines by their treating physicians (RR: 0.71 [95% CI: 0.51–0.99]) when compared with the other sources of information (18%) with statistically significant contribution made by the physicians (p<0.05). About 67% of the public stored their medicines at room temperature. Majority (83.75%) of the study participants reported that they disposed unused and expired drugs in the dustbin. Only 42.5% of the public knew the detrimental effect of improper drug disposal on human health and our ecosystem. In addition, 80% (320/400) of the participants confirmed that, given the option, they would prefer to return the unused or expired drugs to the pharmacy shops from where the medicines were purchased. Conclusion: There is a need to educate drug consumers/general public about safe and proper disposal of unused/ expired medicines. Health-care professionals, governments and policymakers should offer training to educate the general public about Indian regulations for safe disposal of unused/expired medicines.
