Knowledge Assessment on Biomedical Waste Management among First Year Allied Health Science Students at Selected College, Chennai

Abstract

Introduction: Biomedical waste generated during healthcare activities poses serious risks to public health and the environment when not handled safely. Despite the implementation of the Biomedical Waste (Management and Handling) Rules in India, gaps in awareness and compliance remain evident across healthcare settings. Knowledge and adherence to biomedical waste management protocols are especially crucial for allied health science students, who form an integral part of the future healthcare workforce. Assessing their understanding and attitude toward safe waste management practices is essential for strengthening infection control and ensuring environmentally responsible healthcare delivery.
Aims: The study aimed to determine the knowledge on biomedical waste generation, health hazards and legislation, Awareness on BMW Management Practices, Attitude towards BMW Management and Needle-Stick Injury Awareness among first year allied health science students.
Methods: A descriptive cross-sectional study was conducted among 102 first year allied health students selected through convenience sampling. Data were collected using structured questionare comprising 35 closed ended questions under four categories: biomedical waste generation, health hazards and legislation, Awareness on BMW Management Practices, Attitude towards BMW Management and Needle-Stick Injury Awareness.
Results: Of the 102 participants, 52.9% exhibited good knowledge and 44.1% showed intermediate awareness of biomedical waste creation, risks, and legislation. The majority of respondents (50%) had intermediate understanding of biological waste management techniques, with good awareness coming in close (42.2%). 70.6% of pupils demonstrated a modest attitude towards safe waste-handling procedures, according to attitude and behaviour assessments. 62.7% of respondents demonstrated good awareness of needlestick injuries. There were significant association found between the course of study and awareness of needlestick injuries (*p = 0.010) and between the course of study and knowledge level (*p= 0.034). Other demographic factors did not exhibit statistical significance.
Conclusion: This study revealed that the first year allied health science students possess moderate level of knowledge and attitude towards Biomedical Waste management. Practical compliance and safe waste handling behavior remain insufficient. This demonstrates that students need structured educational intervention and regular training to strengthen the biomedical waste management practices.
