Background: Bio-medical waste (BMW) means any waste, which is generated during the diagnosis, treatment or immunization of human beings or animals or in research activities or in the production or testing of biological or in any health camp activities. Proper management of BMW ensures protection of public health and environment against any adverse effect associated with such waste materials. Several studies have reported that health care workers lack adequate level of awareness and right attitude regarding proper BMW management which ultimately reflects as incorrect practice of handling and disposal of bio medical waste. This study aimed to assess the knowledge, attitude and practices of healthcare workers regarding bio-medical waste management.

Methods: This study was conducted at Tomo Riba Institute of Health and Medical Sciences (TRIHMS), Arunachal Pradesh, India. Hospital based cross sectional study was conducted and questionnaire were administered to 313 healthcare workers of TRIHMS who consented to participate in the study. A predesigned questionnaire for knowledge, attitude and practice study was used for data collection. Data was analysed using Microsoft Excel and STATA 13.

Results: Study results show that the average knowledge score was highest amongst nurses (10±2.6) and least in class IV staffs (7.2±1.9).  Amongst all participants laboratory technicians were mostly average or poor on the attitude score. Overall only 23 percent (n=73) of the healthcare workers were found to be performing good BMW management practice.

Conclusions: Our study revealed that there is significant variation in knowledge, attitude, and practice regarding biomedical waste management among healthcare workers.
