RESUMO
BACKGROUND: Despite current efforts to improve hand hygiene in health care facilities, compliance among birth attendants remains low. Current improvement strategies are inadequate, largely focusing on a limited set of known behavioural determinants or addressing hand hygiene as part of a generalized set of hygiene behaviours. To inform the design of a facility -based hand hygiene behaviour change intervention in Kampong Chhnang, Cambodia, a theory-driven formative research study was conducted to investigate the context specific behaviours and determinants of handwashing during labour and delivery among birth attendants. METHODS: This formative mixed-methods research followed a sequential explanatory design and was conducted across eight healthcare facilities. The hand hygiene practices of all birth attendants present during the labour and delivery of 45 women were directly observed and compliance with hand hygiene protocols assessed in analysis. Semi-structured, interactive interviews were subsequently conducted with 20 key healthcare workers to explore the corresponding cognitive, emotional, and environmental drivers of hand hygiene behaviours. RESULTS: Birth attendants' compliance with hand hygiene protocol was 18% prior to performing labour, delivery and newborn aftercare procedures. Hand hygiene compliance did not differ by facility type or attendants' qualification, but differed by shift with adequate hand hygiene less likely to be observed during the night shift (p = 0.03). The midwives' hand hygiene practices were influenced by cognitive, psychological, environmental and contextual factors including habits, gloving norms, time, workload, inadequate knowledge and infection risk perception. CONCLUSION: The resulting insights from formative research suggest a multi-component improvement intervention that addresses the different key behaviour determinants to be designed for the labour and delivery room. A combination of disruption of the physical environment via nudges and cues, participatory education to the midwives and the promotion of new norms using social influence and affiliation may increase the birth attendants' hand hygiene compliance in our study settings.

BACKGROUND: Newborns delivered in healthcare facilities in low- and middle-income countries are at an increased risk of healthcare associated infections. Facility-based studies have focused primarily on healthcare worker behaviour during labour & delivery with limited attention to hygiene practices in post-natal care areas and largely ignore the wide variety of actors involved in maternal and neonatal care. METHODS: This exploratory mixed-methods study took place in six healthcare facilities in Nigeria where 31 structured observations were completed during post-natal care, discharge, and the first 6 hours after return to the home. Frequency of hand hygiene opportunities and hand hygiene actions were assessed for types of patient care (maternal and newborn care) and the role individuals played in caregiving (healthcare workers, cleaners, non-maternal caregivers). Qualitative interviews with mothers were completed approximately 1 week after facility discharge. RESULTS: Maternal and newborn care were performed by a range of actors including healthcare workers, mothers, cleaners and non-maternal caregivers. Of 291 hand hygiene opportunities observed at health facilities, and 459 observed in home environments, adequate hand hygiene actions were observed during only 1% of all hand hygiene opportunities. Adequate hand hygiene prior to cord contact was observed in only 6% (1/17) of cord contact related hand hygiene opportunities at healthcare facilities and 7% (2/29) in households. Discharge advice was infrequent and not standardised and could not be remembered by the mother after a week. Mothers reported discomfort around telling non-maternal caregivers to practice adequate hand hygiene for their newborn. CONCLUSIONS: In this setting, hand hygiene practices during post-natal care and the first 6 hours in the home environment were consistently inadequate. Effective strategies are needed to promote safe hand hygiene practices within the post-natal care ward and home in low resource, high-burden settings. Such strategies need to target not just mothers and healthcare workers but also other caregivers.

Adequate hand hygiene practices throughout the continuum of care of maternal and newborn health are essential for infection prevention. However, the hand hygiene compliance of facility-based birth attendants, parents and other caregivers along this continuum is low and behavioural-science informed interventions targeting the range of caregivers in both the healthcare facility and home environments are scarce. We assessed the limited efficacy of a novel multimodal behaviour change intervention, delivered at the facility, to improve the hand hygiene practices among midwives and caregivers during childbirth through the return to the home environment. The 6-month intervention was implemented in 4 of 8 purposively selected facilities and included environmental restructuring, hand hygiene infrastructure provision, cues and reminders, and participatory training. In this controlled before-and-after study, the hand hygiene practices of all caregivers present along the care continuum of 99 women and newborns were directly observed. Direct observations took place during three time periods; labour, delivery and immediate aftercare in the facility delivery room, postnatal care in the facility ward and in the home environment within the first 48 h following discharge. Multilevel logistic regression models, adjusted for baseline measures, assessed differences in hand hygiene practices between intervention and control facilities. The intervention was associated with increased odds of improved practice of birth attendants during birth and newborn care in the delivery room (Adjusted odds ratio [AOR] = 4.7; 95% confidence interval [CI] = 2.7, 7.7), and that of parental and non-parental caregivers prior to newborn care in the post-natal care ward (AOR = 9.2; CI = 1.3, 66.2); however, the absolute magnitude of improvements was limited. Intervention effects were not presented for the home environment due COVID-19 related restrictions on observation duration at endline which resulted in too low observation numbers to warrant testing. Our results suggest the potential of a facility-based multimodal behaviour change intervention to improve hand hygiene practices that are critical to maternal and neonatal infection along the continuum of care.

BACKGROUND: Globally, infections are the third leading cause of neonatal mortality. Predominant risk factors for facility-born newborns are poor hygiene practices that span both facilities and home environments. Current improvement interventions focus on only one environment and target limited caregivers, primarily birth attendants and mothers. To inform the design of a hand hygiene behavioural change intervention in rural Cambodia, a formative mixed-methods observational study was conducted to investigate the context-specific behaviours and determinants of handwashing among healthcare workers, and maternal and non-maternal caregivers along the early newborn care continuum. METHODS: Direct observations of hygiene practices of all individuals providing care to 46 newborns across eight facilities and the associated communities were completed and hand hygiene compliance was assessed. Semi-structured interactive interviews were subsequently conducted with 35 midwives and household members to explore the corresponding cognitive, emotional and environmental factors influencing the observed key hand hygiene behaviours. RESULTS: Hand hygiene opportunities during newborn care were frequent in both settings (n = 1319) and predominantly performed by mothers, fathers and non-parental caregivers. Compliance with hand hygiene protocol across all caregivers, including midwives, was inadequate (0%). Practices were influenced by the lack of accessible physical infrastructure, time, increased workload, low infection risk perception, nurture-related motives, norms and inadequate knowledge. CONCLUSIONS: Our findings indicate that an effective intervention in this context should be multi-modal to address the different key behaviour determinants and target a wide range of caregivers.

BACKGROUND: The development of new diagnostics is an important tool in the fight against disease. Latent Class Analysis (LCA) is used to estimate the sensitivity and specificity of tests in the absence of a gold standard. The main field diagnostic for Schistosoma mansoni infection, Kato-Katz (KK), is not very sensitive at low infection intensities. A point-of-care circulating cathodic antigen (CCA) test has been shown to be more sensitive than KK. However, CCA can return an ambiguous 'trace' result between 'positive' and 'negative', and much debate has focused on interpretation of traces results. METHODOLOGY/PRINCIPLE FINDINGS: We show how LCA can be extended to include ambiguous trace results and analyse S. mansoni studies from both Côte d'Ivoire (CdI) and Uganda. We compare the diagnostic performance of KK and CCA and the observed results by each test to the estimated infection prevalence in the population. Prevalence by KK was higher in CdI (13.4%) than in Uganda (6.1%), but prevalence by CCA was similar between countries, both when trace was assumed to be negative (CCAtn: 11.7% in CdI and 9.7% in Uganda) and positive (CCAtp: 20.1% in CdI and 22.5% in Uganda). The estimated sensitivity of CCA was more consistent between countries than the estimated sensitivity of KK, and estimated infection prevalence did not significantly differ between CdI (20.5%) and Uganda (19.1%). The prevalence by CCA with trace as positive did not differ significantly from estimates of infection prevalence in either country, whereas both KK and CCA with trace as negative significantly underestimated infection prevalence in both countries. CONCLUSIONS: Incorporation of ambiguous results into an LCA enables the effect of different treatment thresholds to be directly assessed and is applicable in many fields. Our results showed that CCA with trace as positive most accurately estimated infection prevalence.
