摘要:Background In Uttar Pradesh (UP), India, a new initiative to intro- duce zinc and reinvigorate ORS for diarrhea treatment in the public and private sectors was rolled out in selected districts. We conducted an external evaluation of the program that included assessing the knowledge and practices of private sector providers 6 months after the initial program rollout. Methods We conducted interviews and direct observations among a randomly selected group of formal and informal private sector pro- viders in 12 districts of UP. We calculated summary statistics for re- ported provider characteristics, diarrhea treatment knowledge and preferred treatments, as well as the treatments advised during con- sultation with a child with diarrhea.
