The IRAM Chad impact evaluation will be based on a cluster randomized controlled trial to study the impact of the integrated and multisectoral services package (PASIM), aimed at reducing the incidence and prevalence of wasting through integrated interventions, including, among other things, strengthening the activity of community care groups, food supplementation, water treatment, and screening for wasting conducted by families.
The general objective of the integrated and multisectoral services package (PASIM) is to reduce the incidence and prevalence of wasting through integrated interventions, including, among other things, strengthening the activity of community care groups. The members of the care groups conduct home visits to children aged 6-23 months (or up to 59 months when the children are under treatment for wasting or have been discharged in the previous 6 months) to deliver messages for behavioral change related to complementary feeding, health and hygiene ; deliver nutritional supplement and water purification inputs; improve screening coverage (training and supervision of families to take the Mid-Upper Arm Circumference measurements, referral of malnourished cases); and verify adherence to treatment of malnourished cases, in the health district of Mongo, Guéra province, Chad, Central Africa.
The evaluation of the impact of PASIM will be based on a cluster randomized controlled trial, consisting of 100 villages or clusters of villages. The selected evaluation model will be that of a comparison of control groups (n=50; no implementation of the intervention) and intervention (n=50) through the follow-up of 3 cohorts :
The primary impact results are as follows:
Secondary impact results include, but are not limited to :

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control | No Intervention | The control group receiving the standards of care and the usual activities of the partners without additional support from the IRAM project for the implementation of the PASIM. This includes the usual Community Management of Acute Malnutrition (CMAM) program. This group will also continue to benefit from the BCC and screening services already existing in their areas. | |
| Intervention | Experimental | The PASIM is delivered by the care groups. Each beneficiary is visited at home at least once a month (up to once a week if possible). The package of activities includes : Behavior change communication (all children in care groups) Monthly delivery of a nutritional supplement: limited to [6-11] months old children diagnosed as non-wasted (green MUAC) or for [6-59] months old for 6 months after discharge from the national CMAM program. Monthly delivery of a water purification input: limited to households with [6-11] months old children or with [6-59] months old children under CMAM treatment and for 6 months after discharge. Delivery of micronutrient powders to [12-23] months old children. Screening and referral for [6-59] months old children, formative supervision of MUAC measurement in families. |

Formative supervision of MUAC measurement in families. The training will be carried out by the members of the care groups and at each home visit, they will be able to ensure that the MUAC measurement technique is well mastered by the mother (or another member) and correct the technique if necessary. |
|
| Screening by care group | Behavioral | Monthly screening by the care group volunteers of the children they follow, using the MUAC. Referral to the health center of [6-59] months old children screened as malnourished (result of MUAC orange or red), and follow-up on referral to confirm child was enrolled |

| CMAM compliance | Behavioral | Weekly follow-up of [6-59] months old children under treatment and for 6 months after discharge from the national treatment and consolidation program : care group volunteers follow children under treatment until they recover and for the whole duration of their consolidation (for children cured of severe emaciation) through weekly home visits. They monitor treatment adherence (i.e., families follow the planned schedule of visits and receive inputs for treatment or consolidation) and treatment compliance (i.e., the malnourished or consolidating child receives the planned dose of therapeutic or supplementary food each day). |
