Obstetric Healthcare Workers' Adherence to Hand Hygiene Recommendations during the COVID-19 Pandemic: Observations and Social-Cognitive Determinants

Background Hand hygiene is crucial to avoid healthcare-associated infections and the transmission of COVID-19. Although the WHO has issued global hand hygiene recommendations for healthcare, adherence remains challenging. Considering social-cognitive theories such as thehealth action process approach(HAPA) can help to improve healthcare workers' adherence. This study aimed to observe adherence and to assess determinants in obstetric hospitals during and after the onset of the COVID-19 pandemic. Methods In all, 267 observations of behaviour were conducted in two German obstetric university hospitals over three time periods (pre-COVID-19 pandemic,heightened awareness, andstrict precautions). In addition, 115 healthcare workers answered questionnaires regarding social-cognitive determinants of hand hygiene behaviour. Multiple regression and multiple mediation analyses were used to analyse associations. Results Adherence to hand hygiene recommendations increased from 47 per centpre-COVID-19 pandemicto 95 per cent just before lockdown while simple measures against the pandemic were taken. Self-efficacy was associated with the intention to sanitise hands (beta = .397,p < .001). Coping self-efficacy mediated the association of intention with hand hygiene adherence. Conclusions Obstetric healthcare workers seem to adapt their hand hygiene behaviour to prevent infections facing the global COVID-19 pandemic. To further improve interventions, social-cognitive determinants should be considered, especially intention and (coping) self-efficacy.
