Abstract

Background: The COVID-19 pandemic has emphasized the importance of effective hand hygiene in reducing transmission of infectious diseases. Older adults face increased vulnerability due to age-related risks, co-morbidities, and limited access to digital health information. Understanding their knowledge, attitudes, and practices (KAP) toward hand hygiene is essential for targeted interventions. Materials and Methods: A cross-sectional study was conducted among 202 elderly individuals (?60 years) attending a government tertiary care hospital in Chennai. A validated, structured KAP questionnaire consisting of 27 items was administered after obtaining informed consent and ethical clearance. Data were analysed using SPSS version 26, applying descriptive statistics, Pearson's correlation, and significance testing at p < 0.05. Results: The mean participant age was 68.87 years; 52% were males. Most participants demonstrated adequate knowledge of COVID-19 transmission, with 82.7% reporting exposure to government awareness initiatives. Knowledge scores negatively correlated with age (r = -0.167, p = 0.018). Positive attitudes were reported by the majority, and significant behavioural improvements were observed after the pandemic, including increased handwashing frequency (48.2%), greater use of liquid soap, and higher adoption of hand sanitiser use. However, gaps persisted in correct technique, recommended duration, and key hand-hygiene moments. Conclusion: The pandemic substantially improved hand-hygiene knowledge and practices among elderly persons; however, deficiencies in technique, accessibility, and perceived vulnerability highlight the need for focused health education, improved resource availability, and sustained public-health reinforcement to protect high-risk elderly populations.
