ABSTRACT
The WHO Safe Childbirth Checklist (SCC) was developed to ensure the delivery of essential maternal and perinatal care practices around the time of childbirth. A research collaboration was subsequently established to explore factors that influence use of the Checklist in a range of settings around the world. This analysis article presents an overview of the WHO SCC Collaboration and the lessons garnered from implementing the Checklist across a diverse range of settings. Project leads from each collaboration site were asked to distribute two surveys. The first was given to end users, and the second to implementation teams to describe their respective experiences using the Checklist. A total of 134 end users and 38 implementation teams responded to the surveys, from 19 countries across all levels of income. End users were willing to adopt the SCC and found it easy to use. Training and the provision of supervision while using the Checklist, alongside leadership engagement and local ownership, were important factors which helped facilitate initial implementation and successful uptake of the Checklist. Teams identified several challenges, but more importantly successfully implemented the WHO SCC. A critical step in all settings was the adaptation of the Checklist to reflect local context and national protocols and standards. These findings were invaluable in developing the final version of the WHO SCC and its associated implementation guide. Our experience will provide useful insights for any institution wishing to implement the Checklist.
ABSTRACT
The distribution and stability of human immunodeficiency virus type 1 (HIV-1) in breast milk (BM) components remain largely unknown. Inhibitory effects, if any, of BM on HIV RNA and DNA PCR amplification are poorly understood. We have addressed these issues by using virus-spiked BM samples from HIV-negative women. BM samples from HIV-negative women were spiked with HIV-1 virions or cells containing a single integrated copy of HIV DNA (8E5/LAV). After incubation under different experimental conditions, viral RNA was detected by the Roche Amplicor UltraSensitive assay in whole-milk, skim milk, and lipid fractions. We found excellent correlation between HIV-1 input copy and recovery in whole milk (r = 0.965, P < 0.0001), skim milk (r = 0.972, P < 0.0001), and the lipid fraction (r = 0.905, P < 0.001). PCR inhibition was observed in less than 10% of the spiked samples. Similar levels of inhibition were noted in BM samples collected from HIV-infected women. HIV proviral DNA was detected in BM samples using real-time PCR (linear correlation between the threshold cycle versus log DNA copy number, >0.982). The effects of incubation duration and temperature and repeated freeze-thaw cycles on HIV RNA recovery were analyzed. HIV RNA levels were remarkably stable in whole milk after three freeze-thaw cycles and for up to 30 h at room temperature. Our findings improve the understanding of the dynamics of HIV detection in BM and the conditions for BM sample collection, storage, and processing.
