DESIGN: A systematic review was conducted that adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses.
DATA SOURCES: MEDLINE, Embase, CINAHL, Web of Science, PsycINFO and Google Scholar were searched up to 23 February 2024.
STUDY ELIGIBILITY CRITERIA AND SETTING: Qualitative, quantitative and mixed-method primary research studies. There was no limitation on the publication date, geographical locations or the study settings.
PARTICIPANTS: Pharmacists, doctors, nurses and students from these respective professional groups in any country.
PRIMARY OUTCOME MEASURES: The levels of healthcare staff and students' KAPs about disposal of unwanted medications.
DATE EXTRACTION AND SYNTHESIS: Data extraction was conducted by four of the researchers independently. The study details were categorised into three main domains, that is, KAP using the KAP model. Other relevant information was also extracted, and synthesised in overall themes, such as challenges and recommendations.
RESULTS: Thirty-seven studies from 18 countries (Asia n=21, the USA n=7, Africa n=5, EU n=2, South America n=2) were included. 86.5% (n=32) investigated participants' knowledge of medication disposal. Although there was a good level of awareness about the environmental impacts, there were significant gaps in knowledge regarding correct disposal methods, available services, guidelines and training. Thirty studies explored participants' attitudes towards medication disposal. There was a generally positive attitude towards the need for environmentally safe disposal practices. Thirty-five studies evaluated participants' practices in relation to medication disposal. Although there was generally a positive attitude and some understanding of appropriate disposal methods, the majority of the participants did not follow the practice guidelines, especially outside healthcare settings.
DISCUSSIONS AND CONCLUSIONS: Although healthcare staff and students have fair knowledge and positive attitudes towards medicine disposal, their actual practices are lacking. One significant challenge identified is the limited awareness about proper disposal methods coupled with a lack of established services or guidelines. Even in cases where take-back programmes are available, they often face issues with accessibility. To tackle these challenges, it is suggested that governmental bodies should establish and enforce clear policies on medication disposal while also expanding educational initiatives to increase understanding among professionals and students. Furthermore, improving access to take-back programmes is crucial for ensuring safe medication disposal and minimising potential environmental and health hazards.
PROSPERO REGISTRATION NUMBER: CRD42024503162.
AIMS: To determine the national self-reported incidence and risk factors for NSI among Malaysian Ministry of Health (MOH) HCWs.
METHODS: Using data from the MOH national sharps injury surveillance programme, information on reported NSIs over a 1-year period (2016) for different HCW subgroups were extracted and analysed.
RESULTS: A total of 1234 NSI cases were reported in 2016, giving an overall incidence of 6 injuries per 1000 HCWs. Medical doctors recorded the highest incidence (21.1 per 1000 HCWs) followed by dental staff (7.5), pharmacy staff (4.2), nurses (3.7), medical assistants (3.4) and allied and auxiliary staff (1.0). Doctors had significantly increased risk of NSI compared with allied and auxiliary staff (relative risk [RR] = 20.7, 95% confidence interval [CI] 15.5-27.5), medical assistants (RR = 6.1, 95% CI 4.5-8.2), nurses (RR = 5.7, 95% CI 5.0-6.6), pharmacy staff (RR = 5.0, 95% CI 3.7-6.6) and dental staff (RR = 2.8, 95% CI 2.2-3.5). Significant differences were found in age and sharps- handling experience between occupational subgroups (P < 0.001 for both variables). Male employees had higher risk than females (RR = 1.33, 95% CI 1.18-1.50), with a significant difference seen in their sharps-handling experience (P < 0.01). Important risk factors included unsafe practices such as recapping of needles and their improper disposal.
CONCLUSIONS: The national incidence of NSI amongst Malaysian HCWs was lower compared with other countries, but unsafe practices remain an important concern. There is a need to formulate, implement and monitor safe and consistent practices for the different healthcare professionals.
DESIGN/METHODOLOGY/APPROACH: The authors conducted a gap analysis on recommended practices gathered from the literature and current practices gathered through semi-structured interviews with Malaysian medical personnel. A life cycle approach was adopted covering mercury use: input, storage, handling, accident, waste disposal and governance phases.
FINDINGS: The authors found that there are significant gaps between recommended and current mercury management practices. Analysis indicates improper mercury management as the main contributor to these gaps. The authors found from recommended practices that core components needing improvement include: mercury management action plan, mercury use identification team, purchasing policy, proper guidelines and monitoring systems.
PRACTICAL IMPLICATIONS: This study helps us to understand mercury management practices and suggests essential steps to establish a mercury-free medical facility.
ORIGINALITY/VALUE: This study explored the gaps between recommended and current mercury management practices in a medical facility and contributes to the Minamata Convention on Mercury aspirations.
