ABSTRACT
BACKGROUND:
Sanitation workers are also known as “garbage workers” who play a significant role in the sanitation chain. For many generations sanitation workers’ level of knowledge regarding hygiene practices has remained low due to a lack of educational programmes on hygiene. As a result, they are widely exposed to hygiene-related diseases such as cholera, skin infections and various other diseases, increasing their risk of mortality to 40%. This review aims to explore the global impact of educational programs on the hygiene knowledge and practices of sanitation workers.
METHODS:
The systematic literature search was conducted for studies published between 2013 and 2023 using the following databases: MEDLINE (via EBSCOHost), PubMed, and Google Scholar to identify quantitative studies on the subject. Study quality was assessed using the Joanna Briggs Institute Critical Evaluation Instruments. Data extracted from the included articles was presented using a summary of findings table and presented graphically through charts and tables, employing both descriptive and inferential statistical methods. The PRISMA flow diagram was used to present the article selection process.
RESULTS:
The systematic review included 15 eligible studies from a total of 2777 articles. At least 60% (n=9) of the reviewed studies found educational programmes relating to hygiene to have a positive impact on sanitation workers’ hygiene knowledge and practices. However, most (n=7) studies indicated that the efficacy of programmes on hygiene knowledge and practices is indirectly influenced by educational background, age and work experience (predictor factors).
CONCLUSIONS:
Educational programmes regarding hygiene have the potential to significantly improve sanitation workers' knowledge and practices. Findings also suggest the implementation of active and intensive intervention programmes to improve sanitation workers' hygiene knowledge and practices.
