An interventional study of R-SWITCH integrated intervention package in Acute Malnutrition, Severe, Malnutrition, Child and Wasting, sponsored by International Food Policy Research Institute. Recruiting at 1 site in Ethiopia. Open to participants aged 6 Months to 5 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-24.

The R-SWITCH intervention aims to address the low coverage of treatment for severe wasting (SAM) by leveraging existing community groups to deliver an integrated package focused on prevention, screening, referral, and treatment of SAM. It includes behavior change communication on child nutrition and health, active screening, improved passive screening at health posts, and follow-up of referred cases and those enrolled in outpatient treatment programs (OTP). The primary objectives of the R-SWITCH studies are to assess the intervention's impact on OTP coverage, identify implementation barriers and facilitators, and evaluate its cost-efficiency and cost-effectiveness.
Despite the high mortality risk of severe wasting (also referred to as severe acute malnutrition or SAM), only a small proportion of children with severe wasting are currently identified and admitted to available outpatient treatment programs (OTP). In 2020, an estimated 4.9 million children with severe wasting received treatment, approximately a third of the total burden. Outside of humanitarian settings, this proportion is even lower (estimated to be around 15%). These figures highlight the urgent need to increase treatment coverage to meet the Sustainable Development Goals (SDG), which aim to reduce the prevalence of child wasting to less than 5% by 2025 and less than 3% by 2030. The continuum of care for SAM, from case identification, referral to treatment, and post-treatment follow-up, is hampered by several barriers including caregiver lack of awareness on the risks and treatment services of SAM, stigma related to SAM, poor accessibility to treatment, frequent stockouts of treatment inputs, and the overall workload faced by first-line health workers.
The R-SWITCH intervention will leverage existing community groups to deliver an integrated package aimed at preventing SAM through behavior change communication (BCC) on child nutrition and health, increasing wasting screening coverage through active screening, family-led MUAC and improved passive screening health posts, increasing treatment coverage through follow-up of earlier referred cases, cases enrolled in OTP, and children who completed OTP and recovered.
The primary objectives of the R-SWITCH studies are:
82 studies on the registry are indexed under Severe Acute Malnutrition; 13 are open to participants now.

Started May 2024 (actual). Primary completion is estimated for Sep 2026, 28 months after the start.
Of 32 non-industry interventional studies with no phase under Severe Acute Malnutrition, half reached primary completion within 19 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 28. This study's planned 28 months is above that.
Counting every sponsor, half of 32 studies reached it within 19 months; a quarter within 11 and three quarters within 28.
