Abstract
PURPOSE: The ongoing COVID-19 crisis has drastically changed the practice of biomedical waste (BMW) generation and management. Studies venturing into the facility level preparedness at various levels of healthcare delivery during pandemic situation is the need of the hour. Hence, we did this study to assess the BMW disposal practices amongst secondary and tertiary health facilities during COVID-19 pandemic in Tamil Nadu. MATERIALS AND METHODS: This cross-sectional survey was conducted amongst doctors, nurses and allied healthcare staffs across various departments in 18 public health facilities across six districts of Tamil Nadu. Multivariable logistic regression analysis was done based on the random-intercept model to assess the determinants of BMW disposal practices. The effect size was reported as adjusted odds ratio (aOR) with 95% confidence interval (CI). RESULTS: In total, 2593 BMW disposal observations were made. During nearly three-fourth of the observations (73%), the BMW was disposed of appropriately. Nurses (aOR = 1.54; 95%CI: 1.06-2.23) and doctors (aOR = 1.60; 95%CI: 1.05-2.45), healthcare workers in Paediatrics department (aOR = 1.77; 95%CI: 1.13-2.76), healthcare workers in inpatient department (aOR = 2.77; 95%CI: 1.95-3.94) and injection outpatient department (aOR = 2.69; 95%CI: 1.59-4.47) had significantly better odds of having appropriate BMW disposal practices. CONCLUSION: Our study shows that nearly during three-fourth of the observations, healthcare workers performed appropriate BMW disposal practices. However, measures should be taken to achieve 100% compliance by healthcare workers especially the target groups identified in our study by allocating appropriate resources and periodically monitor the BMW disposal practices.
