Knowledge, Attitude and Practice of Biomedical Waste Management among Intern Doctors at a Tertiary Care Centre in Eastern India

Abstract

Objective: To assess the knowledge, attitudes, and practices (KAP) regarding biomedical waste (BMW) management among intern doctors at a tertiary care center in Eastern India.

Methods: An observational, cross-sectional study was conducted between August and December 2024, involving 150 intern doctors from a medical college in Eastern India. Data were collected using a structured, pretested questionnaire encompassing 30 KAP-related items. Descriptive and inferential statistical analyses were performed using SPSS version 16.0, with a significance level of p<0.05.

Results: Out of 150 interns, data of 139 participants who returned completed questionnaire (mean age: 24.3 ± 1.2 years; 52.5% males) were analysed. The mean scores for knowledge, attitude, and practice were 7.19 ± 2.14, 7.83 ± 1.77, and 6.88 ± 1.91, respectively. Interns demonstrated strong knowledge in areas such as sharps disposal (80.6%) and color-coded segregation (79.1%) but showed gaps in understanding specific protocols like sodium hypochlorite concentration (54.7%). Attitudes were generally favourable, with 93.5% recognizing the necessity of safe disposal. However, 51.8% perceived BMWM as an added burden. Practices such as proper PPE use (90.6%) and immediate sharps disposal (82.7%) were adhered to, but participation in audits (29.5%) and protocol reviews (63.3%) was limited.

Conclusions: Intern doctors displayed moderate KAP levels regarding BMW management, with significant gaps in specific knowledge and inconsistent practices. Targeted training programs emphasizing practical application and streamlined workflows are recommended to enhance compliance and foster a culture of safety in healthcare.
