Sustainability, Vol. 12, Pages 11: Investigation and Analysis of Medication Disposal in Hospitals and Community Pharmacies in Taiwan (Sustainability)

Taiwan offers affordable access to health care through the National Health Insurance (NHI) Program, but this increases the risk of waste of medications and pollution caused by improper disposal. This research aimed to: (1) understand methods of disposal of unused medications, and public awareness of related issues, (2) understand the sources and types of unused medications and reasons for their disposal, and (3) propose improvements to current disposal practices. Data on practices and perspectives on the disposal of medications were collected from members of the public using a questionnaire, and subjected to chi-square analysis of demographic variables. The survey found that many respondents disposed of medications inappropriately, but most believed the government should establish a return system. The majority of discarded medications came from hospitals, and were most frequently discarded because patients had forgotten to take them. Based on these findings, the study proposes that receiving stations be established across Taiwan for the safe and environmentally friendly disposal of unused medications, along with a system of monthly checks and compensation for pharmacists’ costs. The study also suggests that pharmacists strengthen medication guidance, spend more time on medication counseling, better understand the reasons for medication waste, and offer health education and advice to physicians and the public.
