This study will be conducted as a stratified cluster randomized trial of a monthly schedule of follow up in the treatment of uncomplicated SAM among children aged 6 to 59 months. The unit of randomization will be the outpatient therapeutic feeding center. The 10 health centers supported by International Medical Corps UK (IMC-UK) will be stratified by size (± 1000 admissions per site per year), and centers within a stratum will be randomized in a 1:1 ratio to one of two schedules of treatment: (1) standard weekly visits or (2) monthly visits with support for home-based surveillance.
