Popis: Introduction: Following a significant recovery from Coronavirus Disease-2019 (COVID-19) pandemic, the world has recognised that Hand Hygiene (HH) and facial masks are key preventive measures against various cross infections, particularly in hospital settings. Studying the incidence of Methicillin Resistant Staphylococcus aureus (MRSA) as a part of Healthcare Associated Infections (HAI) surveillance is crucial, as MRSA transmission can be effectively prevented through HH. Aim: To assess the knowledge and compliance of HH among health personnel using the World Health Organisation (WHO) HH questionnaire. Materials and Methods: A prospective observational study was conducted at Bhaarath Medical College and Hospital, Chennai, Tamil Nadu, India, over one year, from December 2020 to November 2021. The Hospital Infection Control Committee (HICC) team carried out an HH survey using the WHO HH questionnaire to evaluate knowledge and attitudes among 115 Healthcare Workers (HCWs), including doctors and nursing staff, in a tertiary care hospital in Kanchipuram, Southern India. The study also involved monitoring monthly MRSA incidence density rates in Intensive Care Unit (ICU) settings as part of HAI surveillance, followed by regular HH audits. MRSA infectivity rates were statistically analysed using paired t-tests with Statistical Package for Social Sciences (SPSS) software version 21.0 to determine p-values and address standard deviations. Results: In this study, 26 (65%) of doctors had undergone training, while 57 (76%) of nurses reported recent formal HH training. Only 16 (40%) of doctors and 21 (28%) of nurses used alcohol-based handrub. Doctors exhibited knowledge ranging from 60-77.5% on germ transmission and hand rub-related questions, while nurses demonstrated better knowledge ranging from 72-93.3%. HH adherence was 30% among doctors and 72% among nurses. The MRSA infectivity rate varied over the year, starting at 1.33 per 1000 resident days before HH audits and decreasing to 0.3. Each HH audit led to a significant improvement in MRSA rates, with a p-value
