Activity Description: SatelLife has demonstrated that PDAs can reduce the cost and increase the effectiveness of disease detection and management. To prove the concept, the company, in coordination with the Acumen Fund and the Red Cross, distributed PDAs to to the rural health care workers that needed them most. From Ghana to Kenya to Malawi, PDAs changed the speed at which health data is collected, analyzed and used by doctors and health workers to fight disease. The project recorded a 10-fold increase in survey completion speed vs. the traditional paper model, resulting in up to $100K in cost reductions over five measles campaigns that utilized 30 PDAs to collect data faster and more accurately.
