Incidence and predictors of severe acute malnutrition mortality in children aged 6-59 months admitted at Pawe general hospital, Northwest Ethiopia.

Abstract

Severe acute malnutrition (SAM) is defined as a weight-for-height < -3z scores of the median WHO growth standards, or visible severe wasting or the presence of nutritional edema. SAM related mortality rates in under-five children are well documented in Ethiopia but data on their predictors are limited. We aimed to document factors associated with SAM related mortality to inform better inpatient management. A facility-based retrospective cohort study was conducted among children admitted due to SAM at Pawe General Hospital, Northwest Ethiopia, from the 1st of January 2015 to the 31st of December 2019. Data from the records of SAM children were extracted using a standardized checklist. Epi-Data version 3.2 was used for data entry, and Stata version 14 was used for analysis. Bi-variable and multivariable Cox regression analyses were conducted to identify predictors of mortality. Variables with P<0.05 were considered significant predictors of mortality. Five-hundred sixty-eight SAM cases were identified of mean age was 27.4 (SD± 16.5) months. The crude death rate was 91/568 (16.02%) and the mean time to death was determined as 13 (±8) days. Independent risk factors for death were: (i) vomiting AHR = 5.1 (1.35-21.1, p = 0.026), (ii) diarrhea AHR = 2.79 (1.46-5.4, p = 0.002), (iii) needing nasogastric therapy AHR = 3.22 (1.65-6.26, p = 0.001), (iv) anemia AHR = 1.89 (1.15-3.2, p = 0.012), and (v) being readmitted with SAM AHR = 1.7 (1.12-2.8, p = 0.037). SAM mortality was high in under-five children in our setting. The identified risk factors should inform treatment and prevention strategies. Improved community health education should focus on healthy nutrition and seeking early treatment. Inpatient mortality may be reduced by stricter adherence to treatment guidelines and recognizing early the key risk factors for death.
