Time to death and predictors of mortality among asphyxiated neonates in southwest Ethiopia, 2022: prospective cohort study

Abstract

ObjectiveThis study aimed to determine the time to death and predictors of mortality among asphyxiated neonates admitted to public hospitals in the southwest region of Ethiopia.DesignAn institution-based prospective cohort study was conducted.SettingPublic hospitals in southwest Ethiopia.ParticipantsA total of 144 asphyxiated neonates, who were admitted to the neonatal intensive care unit, and their mothers participated from March 2022 to 30 September 2022. Data were entered into EpiData V.4.4.2.1 and exported to STATA V.16 for analysis. The Cox proportional hazards model using bivariate (p<0.25) and multivariate (p<0.05) analyses was used to identify the predictors of mortality. The median survival time was estimated using Kaplan-Meier survival estimates.Primary outcomeTime to death from asphyxia and its predictors in neonates.ResultsThe mortality incidence rate of asphyxiated neonates was 9.1 deaths per 1000 person-days of observation (95% CI: 7.11 to 11.52) with a median survival time of 8 days, and 45.83% (95% CI: 37.81% to 54.08%) of asphyxiated neonates died. Being male (adjusted HR (AHR) 0.32 (95% CI: 0.14 to 0.76)), neonatal sepsis (AHR 0.321 (95% CI: 0.13 to 0.77)), not receiving kangaroo mother care (AHR 0.16 (95% CI: 0. 07 to 0.39)) and vaginal delivery (AHR 0.39 (95% CI: 0.16 to 0.95)) were independent predictors of mortality of asphyxiated neonates.ConclusionsIn this study, asphyxiated neonates had a higher incidence of mortality with a median survival time of only 8 days. Being male, vaginal delivery, not receiving kangaroo mother care and comorbidities such as neonatal sepsis were independent predictors of mortality among asphyxiated neonates. Therefore, healthcare providers and other stakeholders should provide timely initiation of advanced diagnosis and appropriate therapeutic interventions for neonates with asphyxia to reduce neonatal mortality.
