ABSTRACT
Objective: The disposal of unwanted, unused, or expired medicines is a concern. Currently, there is little knowledge regarding their disposal among patients in South Africa. Consequently, there is a need to address this. Methods: This was a descriptive and quantitative study with patients conducted among 16 primary health-care clinics (PHCs) in South Africa. A structured questionnaire was administered to 171 conveniently selected patients. Data on ideal disposal methods were collected and compared to actual disposal practices. Findings: 74.9% of patients reported having unused medicines at home, of whom 34.4% wanted these medicines disposed of. However, 64.9% did not know how to dispose of them, with 95.3% reporting having never been informed by health-care professionals of disposal methods. While patients prefer to return medicines to their PHC, only 7.0% did so. Patients' ideal disposal practices included designated collection task teams (25.1%) and dissolving their unused medicines in water (38.6%). However, current practices indicated that patients flushed medicines down the sewer (31.6%) or disposed of them in municipal bins (23.9%). Conclusion: Patients disposed of their unwanted medicines using incorrect disposal techniques, which they thought were correct. This urgently needs to be addressed.
ABSTRACT
Objective: Professional nurses, pharmacists, and medical practitioners are responsible for disposing of medicines within health-care facilities. South African regulations stipulate that medicines should not be disposed of through sewage systems because of the potential impact on patients and the environment. Consequently, our objective was to determine knowledge and practices among health-care professionals (HCPs) in South Africa and the information they provide to patients regarding the safe disposal of unused/expired/damaged medicines to provide future guidance with identified concerns. Methods: A descriptive study was conducted among 165 HCPs at 16 primary health-care clinics in two subdistricts of the city of Tshwane in Gauteng Province through self-administered questionnaires. Findings: Only 23.5% of HCPs stated that they participated in destroying medicines within their facilities. More than half (65.1%) also reported that they always counsel patients regarding the safe storage of their medicines in their homes, with 27.9% indicating they counsel patients on the safe disposal of their medicines during consultations. More than half (65.1%) also reported that patients never asked about the disposal of medicines. Of concern is that incineration (31.9%), flushing down the toilet (20.6%), and flushing down the sink (9.9%) were regarded by HCPs as correct disposal methods, while 9.6% stated that they did not know the correct methods. In addition, 71.1% reported never receiving training regarding the safe disposal of medicine. Conclusion: There is an urgent need to educate HCPs regarding appropriate medicine waste disposal in South Africa. This can start with including this topic in the curriculum of HCPs, including pharmacists, and continuing post qualification.
