Screening for Acute Malnutrition

This project includes a pilot cluster-randomized trial of the efficacy of training caregivers to screen for acute malnutrition (AM) in children aged 6-59 months using mid-upper arm circumference (MUAC) in Burkina Faso. The pilot will be conducted to establish the feasibility of procedures and preliminary outcome data to inform the sample size calculations and design of a future longer-term, fully powered cluster-randomized trial. Forty communities enrolled in the Bill \& Melinda Gates Foundation-funded Child Health with Azithromycin Treatment (CHAT) trial will be randomly selected for this pilot and randomized to receive the caregiver training intervention or no additional intervention. All communities will continue to receive standard of care screening for AM according to national guidelines, which includes community-based screening for AM by community health workers using MUAC every 6 months. A baseline census will be conducted before randomization to enumerate the eligible population of caregivers and children 6-59 months old and measure MUAC. A final census with MUAC measurement will be conducted 6 months later (primary outcome). Data will be collected on all children presenting to the Centre de Santé et Promotion Sociale (CSPS) for malnutrition to track secondary outcomes. During intervention training, we will also conduct a diagnostic accuracy study to evaluate the validity of caregiver screening by comparing the MUAC measurements of caregivers against the gold standard measurement of the experienced health personnel conducting the training. Also during training, intervention communities will be randomized to one of two training approaches: training by caregivers or training by health agents and adherence to the protocol during follow-up monitoring visits will be compared to determine effectiveness of training.
