Accelerating newborn survival in Ghana through a low-dose, high-frequency health worker training approach: a cluster randomized trial.

BACKGROUND: Newborn deaths comprise nearly half of under-5 deaths in Ghana, despite the fact that skilled birth attendants (SBAs) are present at 68% of births, which implies that evidence-based care during labor, birth and the immediate postnatal period may be deficient. We assessed the effect of a low-dose, high-frequency (LDHF) training approach on long-term evidence-based skill retention among SBAs and impact on adverse birth outcomes. METHODS: From 2014 to 2017, we conducted a cluster-randomized trial in 40 hospitals in Ghana. Eligible hospitals were stratified by region and randomly assigned to one of four implementation waves. We assessed the relative risks (RRs) of institutional intrapartum stillbirths and 24-h newborn mortality in months 1-6 and 7-12 of implementation as compared to the historical control period, and in post-intervention facilities compared to pre-intervention facilities during the same period. All SBAs providing labor and delivery care were invited to enroll; their knowledge and skills were assessed pre- and post-training, and 1 year later. RESULTS: Adjusting for region and health facility type, the RR of 24-h newborn mortality in the 40 enrolled hospitals was 0·41 (95% CI 0·32-0·51; p < 0.001) in months 1-6 and 0·30 (95% CI 0·21-0·43; p < 0·001) in months 7-12 compared to baseline. The adjusted RR of intrapartum stillbirth was 0·64 (95% CI 0·53-0·77; p < 0·001) in months 1-6 and 0·48 (95% CI 0·36-0·63; p < 0·001) in months 7-12 compared to baseline. Four hundred three SBAs consented and enrolled. After 1 year, 200 SBAs assessed had 28% (95% CI 25-32; p < 0·001) and 31% (95% CI 27-36; p < 0·001) higher scores than baseline on low-dose 1 and 2 content skills, respectively. CONCLUSIONS: This training approach results in a sustained decrease in facility-based newborn mortality and intrapartum stillbirths, and retained knowledge and skills among SBAs after a year. We recommend use of this approach for future maternal and newborn health in-service training and programs.

First Molecular Detection of SARS-CoV-2 in Sewage and Wastewater in Ghana.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is shed in the stool of infected individuals and can be detected in sewage and wastewater contaminated with infected stool. This study is aimed at detecting the virus and its potential survival in sewage and wastewater in Ghana. The cross-sectional study included samples from 16 validated environmental surveillance sites in 7 regions of Ghana. A total of 354 samples composed of wastewater (280) and sewage (74) were collected from November 2020 to November 2022. Overall, 17% of the samples were positive for SARS-CoV-2 by real-time PCR, with 6% in sewage and 11% in wastewater. The highest number of positive samples was collected from the Greater Accra Region (7.3%) with the least recorded in the Bono East Region (0.6%). Further characterization of the positive samples using the next-generation sequencing (NGS) approach yielded two variants: Alpha (B.1.1.7) and Delta (AY.36). Attempts to isolate SARS-CoV-2 in the Vero cell line were not successful probably due to the low viral load concentrations (Ct values > 35) or prolonged exposure to high temperatures rendering the virus noninfectious. Our findings suggest that SARS-CoV-2 RNA in sewage and wastewater may not be infectious, but the prevalence shows that the virus persists in the communities within Ghana.
