Background: Intensive care patients are at risk for healthcare-associated infections (HCAIs), and hand hygiene (HH) compliance in health-care workers (HCWs) is reportedly low. This study aimed to compare closed-circuit television (CCTV) monitoring to direct observation on the HH compliance and its impact on HCAIs. Methods: In a prospective cohort study, HCWs were observed for HH compliance and HCAIs were studied. The study period was August 1, 2014–December 31, 2014 (direct observation period), and March 1, 2015–July 31, 2015 (CCTV monitoring period), with 2 months washout period. A HH education module (running a video daily, reinforcement of HH everyday evening, 2-weekly classes about HH importance, and posters reinforcing the importance of HH on the prominent sites of pediatric intensive care unit) was implemented in both periods. Each day was divided into blocks of 6-h. One hour from each block was randomly selected stratified by day and night shifts. HH compliance was observed according to the World Health Organization, “My Five Moments of HH.” Results: A total of 751 patients (direct observation period n = 369, CCTV monitoring period n = 382) were admitted. The HH compliance rate was higher in the CCTV monitoring period (56.6%, n = 5953 / 10519) as compared to that of the direct observation period (36.1%, n = 2178 / 6028) (relative risk = 1.57, 95% confidence interval: 1.51 - 1.63, P ≤ 0.001). Ventilator-associated pneumonia (4.7 vs. 12 / 1000 ventilation-day) and central line-associated bloodstream infection (1.9 vs. 6.6 / 1000 central line-day) were lower in the CCTV monitoring period. There was no difference in mortality between the study periods (18.3%, n = 70 / 382 vs. 21.1%, n = 78 / 369, relative risk = 0.87, 95% confidence interval: 0.65–1.16, P = 0.333). Conclusion: CCTV monitoring was associated with improved HH compliance, which was associated with lower HCAIs.
