We are used to reading paper after paper saying that CHWs can do this and they can do that, so many that I wonder about the potential burden being placed on them. I was expecting this paper to have the same result. But no, in fact 'Despite extensive training, [CHWs] could not consistently identify signs and symptoms associated with omphalitis in the subâ€Saharan African setting'. Citation and abstract below.

Objective: Omphalitis, or umbilical cord infection, is an important cause of newborn morbidity and mortality in lowâ€resource settings. We tested an algorithm that taskâ€shifts omphalitis diagnosis to communityâ€level workers in sub-Saharan Africa.
Methods: Community-based field monitors and Zambian paediatricians independently evaluated newborns presenting to health facilities in Southern Zambia using a signs and symptoms checklist. Responses were compared against the paediatrician's gold standard clinical diagnosis.
Results: Of 1009 newborns enrolled, 6.2% presented with omphalitis per the gold standard clinical diagnosis. Paediatricians' signs and symptoms with the highest sensitivity were presence of pus (79.4%), redness at the base (50.8%) and newborn flinching when cord was palpated (33.3%). The field monitor's signs and symptoms answers had low correlation with paediatrician's answers; all signs and symptoms assessed had sensitivity <16%.
Conclusion: Despite extensive training, field monitors could not consistently identify signs and symptoms associated with omphalitis in the subâ€Saharan African setting.
Comment: Of course, these findings are as likely to reflect the training as much as the CHWs themselves.
