RESUMO
BACKGROUND: As part of a randomised controlled trial of treatment with placebo versus 3â days of amoxicillin for nonsevere fast-breathing pneumonia among Malawian children aged 2-59â months, a subset of children was hospitalised for observation. We sought to characterise the progression of fast-breathing pneumonia among children undergoing repeat assessments to better understand which children do and do not deteriorate. METHODS: Vital signs and physical examination findings, including respiratory rate, arterial oxygen saturation measured by pulse oximetry (S pO2 ), chest indrawing and temperature were assessed every 3â h for the duration of hospitalisation. Children were assessed for treatment failure during study visits on days 1, 2, 3 and 4. RESULTS: Hospital monitoring data from 436 children were included. While no children had S pO2 90-93% at baseline, 7.4% (16 of 215) of children receiving amoxicillin and 9.5% (21 of 221) receiving placebo developed S pO2 90-93% during monitoring. Similarly, no children had chest indrawing at enrolment, but 6.6% (14 of 215) in the amoxicillin group and 7.2% (16 of 221) in the placebo group went on to develop chest indrawing during hospitalisation. CONCLUSION: Repeat monitoring of children with fast-breathing pneumonia identified vital and physical examination signs not present at baseline, including S pO2 90-93% and chest indrawing. This information may support providers and policymakers in developing guidance for care of children with nonsevere pneumonia.
