Medical students should have adequate Infection control knowledge for better compliance. This study aimed to assess the effectiveness of structured training on improving the infection control practices.

This study is a quasi-experimental type with before and after design. Proforma encompassing Knowledge of student towards Infection control practices under five domains was used. Following this a structured package of educational intervention comprised of one day Continued Medical Education, Audio Visual Demonstration followed by bedside real time hands on training on infection control practices was provided. Finally knowledge and skill was assessed by Objective structured practical examination (OSPE) and post-test questionnaire. Domain wise proportions of correct responses were compared between pre and post intervention using z test.

A total of 382 Medical undergraduate students participated.Of the five domains, biomedical waste management (43%) and personal protective equipment (52%) got least scoring.. Knowledge was more in the domain of antibiotic resistance (72%) and hand washing (60%). Invariably, all five domains showed significant knowledge improvement from the baseline to immediately after training as well as six months later. [Proportion of correct knowledge on personal protective equipments: pretest-52% Vs immediate post intervention: 93% Vs 6 months post intervention: 88.4%, p<0.0001; Biomedical waste management: 43% Vs 93% Vs 88.6%, p<0.0001; transmission based precautions: 55% Vs 88% Vs 83.4%, p<0.0001]

The overall knowledge on Infection control practices of medical students was low initially but improved drastically following the structured educational intervention programme.
