Risk Factors For Pneumonia Mortality In Under-Five Children In A Tertiary Care Hospital Of Darjeeling District Of West Bengal: A Prospective Case-Control Study

Background: Among children admitted with pneumonia, several modifiable predictors have been identified for deaths in children in hospitals. Despite the presence of a several national programs designed to address most of the risk factors directly or indirectly it is surprising that they continue to be common in children with pneumonia. Objectives: The objective is to determine the risk factors for pneumonia mortality in under-five children in a tertiary care hospital of Darjeeling district of West Bengal. Methods: An analytical study with case-control design was conducted between May 2016 and October 2017. Children aged 2-59 months admitted with the diagnosis of pneumonia were followed up after admission and who died were recruited as cases and two consecutive age- and sex-matched controls were recruited among children who were declared cured and discharged. A total of 95 cases and 190 controls were studied and the risk factors were compared in the pair matched groups by the conditional logistic regression. Results: Factors influencing childhood pneumonia mortality were severely underweight (adjusted odds ratio [AOR]: 3.66 [1.28,10.46]) unimmunized child (AOR 4.18 [1.53, 11.41]), lack of exclusive breast feeding (AOR: 3.12 [1.23, 7.91]), past history of diarrhea or acute respiratory infection in the last 3 months (AOR: 7.27 [3.68, 14.36]), hypoxemia on admission (AOR: 2.53 [1.14, 5.61]), sub-center as the first contact health facility (AOR: 6.49 [2.15, 19.67]), and antibiotic not received at first contact (AOR: 3.18 [1.36, 7.43]). Conclusions: Most of the risk factors for death in children between 6 and 59 months of age are directly or indirectly related to health service delivery and can be ameliorated through proper structural and administrative measures.
