Time of recovery and associated factors of children with severe acute malnutrition treated at outpatient therapeutic feeding program in Dire Dawa, Eastern Ethiopia

Background The outpatient therapeutic feeding program is one dimension of the Community Based Management of Acute Malnutrition (CMAM) that provides screening, diagnostic and treatment services for children with Severe Acute Malnutrition (SAM). However, little is known about the program outcomes and factors affecting time to recovery. Objectives To determine median time of recovery and associated factors among under-five children with SAM treated at outpatient therapeutic feeding unit in Dire Dawa, Eastern Ethiopia from January 1st, 2013 to December 31st, 2016. Methods A facility-based retrospective cohort study supplemented with qualitative inquiry was conducted to analyze the records of 713 under-5 children with SAM that were randomly selected from four health centers and one hospital in Dire Dawa. In-depth interviews were conducted with five health professionals. Data was collected from the nutrition registration log book by using structured check lists. The collected data were entered into EPI-data version 3.1 software and exported to SPSS version 23 for analysis using Kaplan Meir and Cox proportional hazard regression. Results The overall recovery rate was 569 (79.8%). Eighty (11.2%) defaulted, 27 (3.8%) were non-responders, 4 (0.6%) died and 15 (2.1%) were transferred-out. The median recovery time was 8.7 weeks (IQR: 5.0-14 weeks). Children with an admission weight of >= 7kg (AHR = 1.73, 95% CI: (1.41-2.14), children who were dewormed (AHR = 1.44, 95% CI: (1.01-2.06) and children with weight gain of >= 8g/kg/day (AHR = 5.76, 95% CI: (4.51-7.38) had higher probability of recovering faster. However, marasmic children stayed longer in treatment (AHR = 0.51, 95% CI: (0.37-0.71) and a low Plumpy Nut consumption rate (g/day) (AHR = 0.79) was associated with longer time of stay on treatment. Conclusion The recovery rate was within the level specified in the Sphere International standards which is > 75%. A higher weight at admission, taking deworming and a steady weight gain were positively associated with a fast recovery time. Appropriate nutritional therapy and management of SAM as per the national protocol will be helpful to overcome lower weight gain and higher length of stay on treatment.
