Differences in psychosocial determinants of hand hygiene between health care professional groups: insights from a mixed-methods analysis

Background: Good hand hygiene (HH) prevents health care-associated infections. We compared psychosocial and organizational factors associated with HH compliance and perceived need for improvement among physicians, nurses, and allied health professionals (AHPs). Methods: We conducted a mixed-methods study in a 1,600-bed adult tertiary-care hospital in Singapore. Seven focus group discussions were conducted and data were analyzed using thematic analysis. The subsequent cross-sectional survey involved 1,064 staff members. Principal components analysis was performed to derive the latent factor structure that was applied in multivariable analyses. Results: All staff members acknowledged that HH was an integral part of their work, but were noncompliant due to competing priorities. Physicians were forgetful but appreciated reminders. Nurses were intrinsically motivated for HH. After adjusting for gender, staff category, seniority, and dermatitis history, having positive knowledge-attitudes-behaviors (odds ratio [OR], 1.44; 95% confidence interval [CI], 1.23-1.69), personal motivators-enablers (OR, 1.60; 95% CI, 1.38-1.86), and emotional motivators (OR, 1.62; 95% CI 1.40-1.88) were positively associated with good HH compliance. Women (OR, 3.91; 95% CI, 1.37-11.11), seniors (OR, 2.88; 95% CI, 1.08-7.68), nurses (OR, 4.05; 95% CI, 1.51-10.87), and staff with personal motivators-enablers for HH (OR, 1.60; 95% CI, 1.08-2.37) were more likely to perceive a need for improvement. Conclusions: Factors influencing self-reported HH differed between health care professional groups. Group-specific interventions are needed to improve compliance
