Abstract

Addressing the underlying drivers of biomedical waste management practices at Tanga Regional Referral Hospital (TRRH) is essential for protecting healthcare workers and the wider community. This study characterized types and quantities of biomedical solid waste generated, assessed the BMW management practices and identified key drivers influencing adherence to recommended practices. A cross sectional design was employed with quantitative research methods, seventy-four (74) healthcare workers were sampled. Data were collected through structured questionnaires, direct observation, and document review. Data were analyzed using descriptive statistics and multivariate logistic regression to identify predictors of proper BMW management. Research was guided by Health Belief model (HBM) and Waste Management Hierarchy theories (WMH). TRRH generates 1,313 kg of biomedical waste weekly 60.8% (798 kg) highly infectious and 39.2% (515 kg) infectious. The study reveals gap in adherence to BWM practices. 81% (n=60) of staff received BMW training, training alone was not a significant predictor of compliance (p>0.05). Instead, full-time employment (OR=4.9, p<0.05) and age 41–50 years (OR=12.9, p<0.05) were statistically significant. These findings indicates that institutional role and experience, drive compliance. The study recommends to implement a color coded segregation system aligned with WHO standards, maintain bins, gear, and storage facilities, and digitize recordkeeping. Apply In service practical training and mentor younger ones and part-time staff and develop a hospital Waste management plan to bridge the gap between knowledge and practice.
