Understanding of Coronavirus Disease 2019 (COVID-19) and the practice of preventive measures among doctors and nurses in a university teaching hospital- A cross-sectional study

ABSTRACT

INTRODUCTION: Knowledge and adequate practice of preventive measures among health care workers (HCWs) are important to reduce the risk of COVID-19 transmission. METHODS: A cross-sectional study was conducted among doctors and nurses in the medical department in Pusat Perubatan Universiti Kebangsaan Malaysia between November 18, 2020 and December 18, 2020 during the third wave of COVID-19 epidemic in Malaysia. We studied the knowledge and practice of preventive measures of COVID-19 among doctors and nurses in the COVID-19 or sudden acute respiratory infection (SARI) wards and general medical wards. Data was collected using a validated self-designed google form online-questionnaire. RESULTS: A total of 407 subjects completed the study and 80.8% were females;55.8% were aged between 30-39 years;46.4% were medical doctors. The main source of COVID-19 knowledge was the Ministry of Health Malaysia (MOH) website (35.1%). Majority (97%) had sufficient knowledge and 82% practiced proper preventive measures. Doctors had a higher mean knowledge score compared to nurses (p < 0.001). HCWs working in COVID-19 or SARI wards scored higher in knowledge questions compared to those in the general medical wards (p = 0.020). Nurses practiced better preventive measures (p < 0.001). Good knowledge could not be predicted based on professions (OR 0.222, 95% CI 0.048 - 1.028, p = 0.054). Majority were unable to recall the proper steps of donning (85.8%) and doffing (98.5%). CONCLUSIONS: Although majority had good knowledge and practiced proper preventive measures, there was a poor recall in donning and doffing steps regardless of place of practice. The MOH website is a useful platform for tailored continuous medical education and regular updates on COVID-19. Regular training and retraining on donning and doffing of PPE is needed to bridge this gap.
