Hygiene practices during clinical training: knowledge, attitudes and practice among a cohort of South Asian Medical students

Abstract Background Proper hygienic practices are important in preventing nosocomial infection. This study aimed to determine knowledge, attitudes and practices (KAP) on hand, attire and equipment hygiene during clinical training among medical students at a State Medical Institution in Sri Lanka. Methods This cross-sectional study was conducted among 3rd, 4th and final (5th) year medical students of the Faculty of Medicine, University of Colombo, who had undergone at least 6 months of clinical training. KAP on hand hygiene (HH), attire hygiene (AH) and equipment hygiene (EH) were assessed using a pre-tested, self-administered questionnaire with a Likert-type scale. KAP scores were graded as follows: good ≥75; moderate:74.9–50; unsatisfactory:49.9–25; poor:< 25%. KAP based on duration of training and gender were compared using independent samples t-tests. Results Three hundred thirty-three students participated (mean age 24 ± 1.1 years, male: female = 1: 1.2). Combined KAP scores on hand and attire hygiene were moderate (HH:73%, AH:65%) while equipment hygiene was unsatisfactory (EH:47%). Senior students (5th year) had higher combined KAP and knowledge (K) on hand hygiene (HH KAP 75% vs. 72%, p = 0.01; K:72% vs. 67%, p = 0.001) and equipment hygiene (EH KAP 50% vs. 44%, p = 0.001; K:47% vs. 35%, p = 0.001) compared to junior students (3rd/ 4th years). However, they had lower KAP and P scores on attire hygiene (AH KAP 63% vs. 67%, p = 0.006; P:60% vs. 67%, p = 0.004). Female students had better AH compared to male students (KAP:67% vs. 64% p = 0.01; K 71% vs. 66%, p = 0.048; P:66% vs. 62%, p = 0.05). Conclusions Overall, hand hygiene was moderate among medical students and improved with progression of training. Attire hygiene was also graded as moderate but to a lesser extent compared to hand hygiene, lower in males, and declined over time, indicating need for better reinforcement of attire hygiene practices with progression of clinical training. Equipment hygiene was unsatisfactory among most medical students and thus needs to be highlighted as a potential area to be improved during clinical training. This study suggests that knowledge, attitudes and practices on equipment and attire hygiene among medical students was less satisfactory and needs to receive greater emphasis during medical clinical training.
