Acute Malnutrition in Childhood
Conditions
Brief summary
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.
Interventions
OTHERCaretaker MUAC screening - training by health workers
Study personnel will train caregivers to conduct weekly AM screening using the color-coded MUAC tape. AM screening will involve identifying the midpoint of the child's right arm, wrapping the tape around the mid-point, inserting one end of the tape through the slit at the other end, pulling the tape secure, and reading the measurement based on the color bands. Caregivers will be trained to refer children with yellow or red readings to the nearest CSPS and will be provided with a referral slip to do so. Caregivers will be informed of the signs, symptoms, and consequences of malnutrition as well as the available nutritional programs. Study personnel will conduct monthly supervision visits including brief refresher trainings. In all study communities, standard of care screening for AM will continue. This includes biannual community-based screening by community health workers as well as weekly malnutrition days led by the CSPS.
OTHERCaretaker MUAC screening - training by caregivers
Study personnel will train a group of caregivers to perform AM training of all caregivers living in their communities. they will instruct caregivers to conduct weekly AM screening. Training will include the same information as the communities receiving training by Health workers: MUAC training and how to interpret MUAC as well as key concepts of malnutrition. Caregivers will be trained to refer children with yellow or red readings to the nearest CSPS and will be. In all study communities, standard of care screening for AM will continue. This includes biannual community-based screening by community health workers as well as weekly malnutrition days led by the CSPS.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Community-level mean mid-upper arm circumference (MUAC) | 6 months | Community-level mean MUAC in children 6-59 months of age as assessed during the final census after 6 months of intervention |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Sensitivity | 6 months | Diagnostic accuracy study comparing caregiver measurements to the gold standard measurement from study personnel will include sensitivity as an outcome measure, defined as the number of true positives divided by the total number of cases of global acute malnutrition (MUAC \< 125 mm) |
| Specificity | 6 months | Diagnostic accuracy study comparing caregiver measurements to the gold standard measurement from study personnel will include specificity as an outcome measure, defined as the number of true negatives divided by the total number of children without global acute malnutrition (MUAC \< 125 mm) |
| Cases referred | 6 months | Number of cases of AM referred to the CSPS during the study period as collected at the CSPS |
| Mid-upper arm circumference (MUAC) at admission | 6 months | MUAC among children 6-59 months of age at admission to CSPS nutritional programs during the study period as routinely collected at the CSPS |
| Effectiveness of caregiver training | 6 months | Adherence to protocol in the communities with caretakers training compared to health workers training as measured by caregiver survey and supervisor monitoring checklist. Relevant items from each data collection source will be summarized into a single summary score. |
