Abstract

Background: Pneumonia and malaria are the leading causes of global childhood mortality. We describe the clinical presentation of children diagnosed with pneumonia and/or malaria, and identify possible missed cases and diagnostic predictors.

Methods: Prospective cohort study involving children (aged 28 days to 15 years) admitted to 12 secondary-level hospitals in south-west Nigeria, from November 2015 to October 2017. We described children diagnosed with malaria and/or pneumonia on admission and identified potential missed cases using WHO criteria. We used logistic regression models to identify associations between clinical features and severe pneumonia and malaria diagnoses.

Results: Of 16 432 admitted children, 16 184 (98.5%) had adequate data for analysis. Two-thirds (10 561, 65.4%) of children were diagnosed with malaria and/or pneumonia by the admitting doctor; 31.5% (567/1799) of those with pneumonia were also diagnosed with malaria. Of 1345 (8.3%) children who met WHO severe pneumonia criteria, 557 (41.4%) lacked a pneumonia diagnosis. Compared with "potential missed" diagnoses of severe pneumonia, children with "detected" severe pneumonia were more likely to receive antibiotics (odds ratio [OR], 4.03; 2.63-6.16, P < .001), and less likely to die (OR, 0.72; 0.51-1.02, P = .067). Of 2299 (14.2%) children who met WHO severe malaria criteria, 365 (15.9%) lacked a malaria diagnosis. Compared with "potential missed" diagnoses of severe malaria, children with "detected" severe malaria were less likely to die (OR, 0.59; 0.38-0.91, P = 0.017), with no observed difference in antimalarial administration (OR, 0.29; 0.87-1.93, P = .374). We identified predictors of severe pneumonia and malaria diagnosis.

Conclusion: Pneumonia should be considered in all severely unwell children with respiratory signs, regardless of treatment for malaria or other conditions.
