Awareness of biomedical waste management among dental professionals and auxiliary staff in Amritsar, India

The aim of this study was to determine awareness of biomedical waste (BMW) management policies and practices among dental professionals and auxiliary staff in a dental hospital/clinics in Amritsar, India, to inform the development of future policies for effective implementation of BMW rules.The study involved 160 staff members at the Amritsar hospital/clinics (80 dentists and 80 auxiliary staff) to whom a questionnaire was distributed regarding policies, practices and awareness relating to BMW. The questionnaire was first piloted. Completed questionnaires were returned anonymously. The resulting data were statistically tested using the chi-square test for differences between the dentists and auxiliary staff.In respect of BMW management policies, there was a highly significant difference in the responses of the dentists, whose answers suggested far greater knowledge than that of the auxiliaries (P0.001). Regarding BMW management practices, the dentists were significantly more aware (P0.001) of the method of waste collection in the hospital and the disposal of various items into different colour-coded bags. As for employee education/awareness, there was a significant difference (P0.05) between the dentists and the auxiliaries on the question regarding records of BMW maintained in the hospital and the other responses to questions on these topics had a highly significant (P0.001) difference between the two groups in favour of the dentists.The results of this study have demonstrated a lack of awareness of most aspects of BMW management among dental auxiliary staff in the dental hospital/clinics in Amritsar and a lack of awareness of some aspects among dentists who work in the hospital/clinics. The results provide the hospital authorities with data upon which they can develop a strategy for improving BMW management.
