Abstract

Introduction: Hand hygiene (HH) is essential for preventing healthcare-associated infections (HAIs), especially in ICUs and cancer care centers. These settings often involve immunocompromised patients and invasive devices, making HH critical for patient safety. Despite its recognized importance, consistent adherence to HH practices by healthcare workers (HCWs) remains a significant challenge. Aim and Objective: This study aimed to evaluate HH compliance in a tertiary care hospital in South India using a customized Android application aligned with WHO guidelines. Materials and Methods: This observational study was conducted across high-risk areas of a tertiary care hospital from June 2019 to May 2024. The hospital's high-risk units, under medical, surgical, and pediatric alliances, were included. An Android application based on the Ibhar platform and WHO hand hygiene audit guidelines was used for data collection. The study recorded HH opportunities, Complete HH Adherence (HHCAR), Partial HH Adherence (HHPAR), and Total HH Adherence (HHTAR). The data were analyzed for location-specific, profession-specific, and moment-specific compliance rates. Results: A total of 196,252 HH opportunities were recorded, with the surgical alliance accounting for the highest number. Pediatric units had the highest compliance, with an HHTAR of 89% and an HHCAR of 66%. Nurses demonstrated the highest compliance among professions, with an HHTAR of 82.8%. Compliance was higher after patient care moments compared to before. Statistically significant differences were noted across different specialties and moments. Conclusion: This large-scale study highlights the variation in HH compliance across different specialties and the need for targeted training sessions. Given the resource constraints in many tertiary care centers, focusing audits on high-risk areas is practical. The use of software-based applications like Ibhar enhances data collection and analysis, making the audit process more efficient. Regular HH audits and behavioral changes are essential to improve and sustain high standards of HH compliance, ultimately contributing to better infection control practices.
