Time to recovery and predictors among admitted preterm neonates in the neonatal intensive care units of public hospitals of Addis Ababa, Ethiopia, 2021.

INTRODUCTION

Ethiopia implemented measures to reduce preterm mortality, and much is currently being done to avoid preterm death, yet preterm death remains the top cause of infant death. As a result, evaluating median time of recovery and determinants will provide information to planners and policymakers to design strategies to improve preterm survival.

METHODS

Hospital-based retrospective follow-up study was conducted in four selected public hospitals of Addis Ababa from September 2018 to August 2021. Data were collected using a pretested structured questionnaire. Epi-data 4.6 and STATA Version 16 were used for data entry and analysis. Kaplan-Meier survival curve, log-rank test, and median time were computed. To find predictors of time to recovery, a multivariable Cox proportional hazards regression model was fitted, and variables with a p-value less than 0.05 were considered statistically significant.

RESULTS

A total of 466 preterm babies were included in the study of which 261 (56.1%) preterm neonates survived and were discharged from NICUs. The median time to recovery was 10 days (95% CI: 9-12). Low birth weight (Adjusted hazard-ratio [AHR]: 1.91, 95% CI: 1.2-3.06), normal birth weight (AHR: 2.09, 95% CI: 1.16-3.76), late preterm (AHR: 1.91, 95% CI: 1.02-3.55), no hospital-acquired infection (AHR: 2.19, 95% CI: 1.36-3.5), no thrombocytopenia (AHR: 1.96, 95% CI: 1.27-3.02), continuous positive airway pressure (AHR: 0.66, 95% CI: 0.48-0.91), and kangaroo mother care (AHR: 2.04, 95% CI: 1.48-2.81) were found to be independent predictors of time to recovery of preterm babies.

DISCUSSION/CONCLUSION: The recovery rate was found relatively low. Several predictors of preterm recovery time were discovered in the study. The majority of predictors were preventable or treatable. Therefore, emphasis should be given towards prevention and early anticipation, and management of these predictors. Studies to assess the quality of care and cause of low survival rate of preterm infants are recommended.
