Performance of low-literate community health workers treating severe acute malnutrition in South Sudan.

Previous studies have described barriers to access of childhood severe acute malnutrition (SAM) treatment, including long travel distances and high opportunity costs. To increase access in remote communities, the International Rescue Committee developed a simplified SAM treatment protocol and low-literacy-adapted tools for community-based distributors (CBD, the community health worker cadre in South Sudan) to deliver treatment in the community. A mixed-methods pilot study was conducted to assess whether low-literate CBDs can adhere to a simplified SAM treatment protocol and to examine the community acceptability of CBDs providing treatment. Fifty-seven CBDs were randomly selected to receive training. CBD performance was assessed immediately after training, and 44 CBDs whose performance score met a predetermined standard were deployed to test the delivery of SAM treatment in their communities. CBDs were observed and scored on their performance on a biweekly basis through the study. Immediately after training, 91% of the CBDs passed the predetermined 80% performance score cut-off, and 49% of the CBDs had perfect scores. During the study, 141 case management observations by supervisory staff were conducted, resulting in a mean score of 89.9% (95% CI: 86.4%-96.0%). For each performance supervision completed, the final performance score of the CBD rose by 2.0% (95% CI: 0.3%-3.7%), but no other CBD characteristic was associated with the final performance score. This study shows that low-literate CBDs in South Sudan were able to follow a simplified treatment protocol for uncomplicated SAM with high accuracy using low-literacy-adapted tools, showing promise for increasing access to acute malnutrition treatment in remote communities.

Severe acute malnutrition treatment delivered by low-literate community health workers in South Sudan: A prospective cohort study.

BACKGROUND: Community health worker (CHW)-delivered acute malnutrition treatment programs have been tested previously, but not with low-literate/-numerate cadres who operate in areas with the highest malnutrition burden and under-five mortality rates. The International Rescue Committee developed low-literacy-adapted tools and treatment protocol to enable low-literate/-numerate community-based distributors (CBD, the CHW cadre in South Sudan) to treat children for severe acute malnutrition (SAM) in their communities. METHODS: We conducted a prospective cohort study in March-September 2017, with 44 CBDs enrolling a total of 308 SAM children into treatment in their communities. Child treatment outcomes and length of treatment were documented. Uncomplicated SAM cases, defined for our study as children with mid-upper arm circumference (MUAC) of 90 to <115 mm or bilateral pitting oedema, without any medical complications, were treated for up to 16 weeks, and were considered fully recovered when they reached MUAC≥125 mm for two consecutive weeks. RESULTS: The recovery rate from the severe to the moderate acute malnutrition (MAM) cut-off of MUAC 115 mm was 91% (95% confidence interval (CI) = 88%-95%). The median length of treatment was five weeks. The recovery rate of children from SAM to full recovery was 75% (95% CI = 69%-81%). The median time to full recovery was eight weeks. The recovery rates reported here exclude children referred for care from the denominator, per standard reporting of acute malnutrition treatment recovery rates. When the data were compared against routine monitoring and evaluation data from nearby static clinics, children treated by CBDs appeared to have improved continuity of care and shorter time to recovery. CONCLUSIONS: The recovery rate for SAM children enrolled in acute malnutrition treatment by low-literate CBDs shows promise that deploying CHWs to treat SAM in areas with high prevalence and low treatment access may lead to higher recovery, better continuity of care in the transition between SAM and MAM, and shorter treatment time. Proper adaptations of tools and protocols can empower CHW cadres with low literacy and numeracy to successfully complete treatment steps. Key questions of scalability and cost-effectiveness remain.
