    Effectiveness of sms technology on timely community health worker follow-up for childhood malnutrition: A retrospective cohort study in sub-Saharan Africa
    (U.S. Agency for International Development, 2018) Sarma, Shohinee; Nemser, Bennett; Cole-Lewis, Heather
    The Millennium Villages Project facilitated technology-based health interventions in rural under-resourced areas of subSaharan Africa. Our study examined whether data entry using SMS compared with paper forms by community health workers (CHWs) led to higher proportion of timely follow-up visits for malnutrition screening in under-5 children in Ghana, Rwanda, Senegal, and Uganda.: Children under 5 years were screened for malnutrition every 90 days by CHWs using mid-upper arm circumference (MUAC) readings. CHWs used either SMS texts or paper forms to enter MUAC data. Reminder texts were sent at 15 days before follow-up was needed. Chi-square tests assessed proportion of timely follow-up visits within 90 days between SMS and paper groups. Logistic regression analysis was conducted in a step-wise multivariate model. Post-hoc power calculations were conducted to verify strength of associations.
