          Abstract

          Background

          Hand hygiene compliance (HHC) monitoring is almost always done in daytime. Documentation of HHC in healthcare workers (HCWs) is limited during odd hours and nighttime.

          Aim

          The objective of the study was to determine diurnal variation in HHC in different categories of health care workers in tertiary care hospital in North India.

          Methods

          A prospective, observational study was conducted in three COVID-19 intensive care units (ICUs) with closed-circuit television (CCTV) cameras. Dedicated infection control nurses monitored HHC among various HCWs (doctors, nursing staff, technicians, hospital and sanitary attendants) during day and nighttime, in 20- minute durations. The difference in HHC by-professional category and for each WHO moment was assessed using chi-square test and p value.

          Findings

          A total of 705 opportunities were observed over a period of seven days, with overall compliance of 53%. Day and nighttime compliance was recorded to be 60.7% and 42.1%, respectively ( p<0.001). HCC was highest amongst resident doctors with little diurnal variation. However, nurses and housekeeping staff exhibited significant diurnal variation. The compliance at “after” moments was much higher than “before” moments in all professional categories.

          Conclusion

          There was a significant decrease in compliance during nighttime, amongst all HCWs, with maximum variation exhibited by nursing staff. The present study underlines the importance of monitoring HHC at odd hours, to elicit a more accurate picture round the clock. Healthcare facilities monitoring compliance only during the daytime may substantially overestimate HHC.

          Compliance with handwashing in a teaching hospital. Infection Control Program.

          Transmission of microorganisms from the hands of health care workers is the main source of cross-infection in hospitals and can be prevented by handwashing. To identify predictors of noncompliance with handwashing during routine patient care. Observational study. Teaching hospital in Geneva, Switzerland. Nurses (66%), physicians (10%), nursing assistants (13%), and other health care workers (11%). Compliance with handwashing. In 2834 observed opportunities for handwashing, average compliance was 48%. In multivariate analysis, noncompliance was higher among physicians (odds ratio [OR], 2.8 [95% CI, 1.9 to 4.1]), nursing assistants (OR, 1.3 [CI, 1.0 to 1.6]), and other health care workers (OR, 2.1 [CI, 1.4 to 3.2]) than among nurses and was lowest on weekends (OR, 0.6 [CI, 0.4 to 0.8]). Noncompliance was higher in intensive care than in internal medicine units (OR, 2.0 [CI, 1.3 to 3.1]), during procedures that carry a high risk for contamination (OR, 1.8 [CI, 1.4 to 2.4]), and when intensity of patient care was high (compared with 60 opportunities: OR, 2.1 [CI, 1.3 to 3.5]). Compliance with handwashing was moderate. Variation across hospital ward and type of health care worker suggests that targeted educational programs may be useful. Even though observational data cannot prove causality, the association between noncompliance and intensity of care suggests that understaffing may decrease quality of patient care.

            Why healthcare workers don't wash their hands: a behavioral explanation.

            To elucidate behavioral determinants of handwashing among nurses. Statistical modeling using the Theory of Planned Behavior and relevant components to handwashing behavior by nurses that were derived from focus-group discussions and literature review. The community and 3 tertiary care hospitals. Children aged 9-10 years, mothers, and nurses. Responses from 754 nurses were analyzed using backward linear regression for handwashing intention. We reasoned that handwashing results in 2 distinct behavioral practices--inherent handwashing and elective handwashing--with our model explaining 64% and 76%, respectively, of the variance in behavioral intention. Translation of community handwashing behavior to healthcare settings is the predominant driver of all handwashing, both inherent (weighted beta =2.92) and elective (weighted beta =4.1). Intended elective in-hospital handwashing behavior is further significantly predicted by nurses' beliefs in the benefits of the activity (weighted beta =3.12), peer pressure of senior physicians (weighted beta =3.0) and administrators (weighted beta =2.2), and role modeling (weighted beta =3.0) but only to a minimal extent by reduction in effort (weighted beta =1.13). Inherent community behavior (weighted beta =2.92), attitudes (weighted beta =0.84), and peer behavior (weighted beta =1.08) were strongly predictive of inherent handwashing intent. A small increase in handwashing adherence may be seen after implementing the use of alcoholic hand rubs, to decrease the effort required to wash hands. However, the facilitation of compliance is not simply related to effort but is highly dependent on altering behavioral perceptions. Thus, introduction of hand rub alone without an associated behavioral modification program is unlikely to induce a sustained increase in hand hygiene compliance.
