KNOWLEDGE AND APPLICATION OF INFECTION PREVENTION AND CONTROL PRACTICES AMONG MEDICAL INTERNS IN A TERTIARY CARE TEACHING HOSPITAL: AN ANALYTICAL CROSS-SECTIONAL STUDY

Abstract

Infection prevention and control (IPC) practices are essential for reducing healthcare-associated infections and antimicrobial resistance, particularly among medical interns involved in direct patient care. This analytical cross-sectional study assessed knowledge, perceptions, self-reported application of IPC practices, and factors associated with application among medical interns in a tertiary care teaching hospital from January to June 2025. Universal sampling was used, and 73 eligible interns participated. Data were collected using a structured electronic questionnaire with expert content review and pilot testing. The median-based nonparametric tests and Spearman correlation were used for analysis. The mean knowledge score was 9.51 ± 1.38 out of 12, while mean perception and application scores were 52.50 ± 4.52 out of 60 and 54.03 ± 6.40 out of 60, respectively. Knowledge gaps were identified in transmission-based precautions (39.7%) and recommended bleach concentration for surface disinfection (41.1%). Knowledge and application were not significantly correlated (ρ=0.147, p=0.215), whereas perception showed a moderate positive correlation with application (ρ=0.490, p<0.001). Application scores differed significantly across clinical departments (p=0.007). The most frequently reported barriers were lack of time (58.9%) and fatigue/workload (46.6%). Medical interns demonstrated relatively good knowledge, positive perceptions, and satisfactory self-reported application of IPC practices, but specific knowledge and behavioral gaps remain. Regular refresher training, simulation-based learning, supervision, and audit-feedback may help reinforce consistent IPC practices.
