Evidence Action

Non-profit scaling evidence-based health interventions

Overview

Evidence Action reduces poverty and improves health by scaling proven, cost-effective interventions in low-income regions. Its programs include Deworm the World, which works with governments to run national school-based deworming programs, and Dispensers for Safe Water, which installs chlorine dispensers at rural water sources to provide safe drinking water. The organization supports governments, communities, and other nonprofits by delivering programs that have been rigorously evaluated for impact and cost efficiency, relying on charitable donations, grants, and partnerships to fund scaling. Unlike groups that offer generic aid, Evidence Action emphasizes evidence-based results and tight use of resources to achieve measurable improvements. The goal is to reach millions more people with proven health and poverty-reduction interventions and to demonstrate clear, scalable impact.

Simplify's Take

What believers are saying

  • GiveWell added roughly $3.7 million in January 2026 for African chlorination pilots.
  • India's February 2026 SPM NIWAS partnership deepens Evidence Action's policy access.
  • India's 2026 rural-water budget commits about $58 billion over five years, expanding demand.

What critics are saying

  • Evidence Action relies heavily on GiveWell and a few foundations for program capital.
  • Revelio Labs shows 2025 headcount fell 3.2%, signaling tighter operating capacity.
  • Government adoption gates everything; if Andhra Pradesh stalls, India chlorination growth freezes.

What makes Evidence Action unique

  • Evidence Action turns randomized evidence into government-run programs, not perpetual NGO delivery.
  • Deworm the World has delivered 2.2 billion treatments since 2014.
  • Safe Water Now installs in-line chlorination, a cheap, automated intervention at village sources.

Evidence Action and CIDRZ survey shows high syphilis screening and treatment in ANC, highlights need for improved counselling and provider training.

Evidence Action and CIDRZ survey shows high syphilis screening and treatment in ANC, highlights need for improved counselling and provider training. April 10, 2026 Owen Chishimba Chibebe shares results of the 2025 Comprehensive Facility Survey on syphilis screening and treatment in antenatal care. Evidence Action in partnership with the Centre for Infectious Disease Research in Zambia (CIDRZ), conducted the 2025 Comprehensive Facility Survey (CFS) to assess the performance of the Ministry of Health's efforts to address gaps in syphilis screening and treatment services during antenatal care (ANC). The survey, which is the primary programme, monitoring activity, measured screening and treatment coverage across trained facilities. Speaking during the CIDRZ research meetings, Senior Monitoring, Learning and Evaluation Officer at Evidence Action, Mr Owen Chishimba Chibebe said the survey sampled 44 facilities from a frame of 837 trained health facilities. He explained that the objective was to estimate coverage of syphilis screening and treatment services by tracking pregnant women attending first ANC, those tested, those who tested positive, and those treated with benzathine penicillin G. Mr Chibebe noted that findings showed strong screening performance, with 90 percent of pregnant women tested for syphilis among trained facilities. In addition, 97 percent of facilities had testing commodities in stock at the time of survey, and 89 percent of providers recalled correct testing guidelines. On treatment coverage, he said 90 percent of syphilis-positive pregnant women received treatment using the alternate ANC approach compared to the 101 percent using the data quality adjustment factor approach, while 94 percent of facilities had benzathine penicillinin stock at the time of survey. All surveyed providers also recalled the correct treatment guidelines. Mr Chibebe highlighted that screening and treatment rates were high, meaning most pregnant women in trained facilities were receiving essential services. However, he noted gaps in counselling, knowledge of congenital syphilis risks, and treatment timing and knowledge of correct dosages. He recommended strengthening provider training, counselling skills, and supportive supervision to improve service delivery and protect mothers and newborns. April 9, 2026 April 8, 2026
