Educational intervention for preventing bloodborne infection among medical students in China

Abstract

Although medical students are known to be at risk for bloodborne infections, there have been no systematic studies, effective intervention programmes, or guidelines for them in China. We developed prevention guidelines, implemented an intervention, and evaluated the effectiveness of knowledge among medical students. This study was designed as a cluster randomised controlled trial. All those who completed a consent form were randomly assigned either to an intervention or to a control group. The intervention group underwent an educational intervention programme consisting of a series of lectures and videos following a baseline survey. The control group completed the same intervention programme after the study was completed. A questionnaire of 25 items was sent to participants three months and nine months after the initial intervention programme. Outcomes measured before and after intervention included knowledge of transmission route, first-aid care, and post-exposure prophylaxis. Pearson's chi(2)-test was used, and the efficacy of students was analysed to control for bias. Intervention in the form of a one-time bloodborne pathogen educational prevention programme for Chinese medical students had little effect on knowledge.
