Background: Infections acquired during labour and delivery are a significant cause of maternal and child morbidity and mortality. Adherence to hand hygiene protocols is a critical component of infection prevention strategies, but few studies have closely examined the hand hygiene of health care providers with sufficient detail to understand infection risks and prioritize prevention strategies. Methods: This observational study was conducted in six healthcare facilities in Nigeria. In each, five women were observed from the onset of labour through to delivery of the placenta. Hand hygiene infection risk was estimated for all procedures requiring aseptic technique compared against adherence to proper hand hygiene protocol and potential recontamination events. Results: Hands were washed with soap and sterile gloves applied with no observed recontamination before only 3% of all observed procedures requiring aseptic technique. There was no significant difference in hygiene compliance between midwives and doctors nor facilities or states. Adherence to proper hygiene protocol was observed more in morning compared to afternoon and night shifts. Conclusions: This study highlights that hand hygiene remains a barrier to delivering high-quality and safe care in health facilities. Improving hygiene practices during labour and delivery will require strategies that extend beyond infrastructure provision.
Many behaviours relevant to public health are part of everyday routines. However, few tools exist to study such behaviours. Here we reintroduce the behaviour setting, a theoretical concept developed in the 1950s, as an approach to the study of routine behaviour. The setting concept bridges theoretical and applied approaches in sociology, psychology and social practice; its components include stage, infrastructure, props, roles, norms, competencies, objectives and resultant routines. We apply settings theory to health-related water use behaviour in rural Nigeria. We captured the dimensions of water use behaviour settings in 23 households at varying distances from newlyintroduced kiosks selling purified water. We found that that routines concerning drinking, laundering, dish washing and handwashing were stable in their settings, varying little between households or by type of water source. Hygiene routines were suboptimal but drinking water was carefully segregated. The findings imply that the majority of water use behaviour was governed, not by an immediate desire to maximise health, but by long-established routines embedded in the social, technical and physical environment. It appears that that water kiosks are making only marginal improvements to the quantity and quality of water being used in homes. Improving public health will require the disruption of settings, for example, through bringing water infrastructure directly to the home, through the sale of new props that facilitate hygienic routines, or in the disruption of gender roles via the promotion of new norms. Settings are an ecologically valid, meso-level theoretical approach that link social and techno-physical environmental factors to behaviour. They provide a comprehensive framework within which to judge avenues for changing routine behaviours. The behaviour settings tool we developed was easy to use, provided a systematic means of capturing the determinants of routine behaviour, and the findings offered insight into methods for disrupting it.
