The Clinton Health Access Initiative (CHAI), with funding from the Bill & Melinda Gates Foundation and IKEA Foundation, partnered with the Governments of Uttar Pradesh, Madhya Pradesh, and Gujarat to support scale-up of zinc and ORS, from 2012-2016. The program focused on ensuring consistent supply and dispensing practices with public and private health providers, and reinforcing messaging among caregivers. Treatment coverage increased significantly since baseline—from 28% to 51% for ORS and from <1% to 34% for zinc, on average across the three focal states. These gains were seen equally, if not more so, among rural and poorer populations. Private providers who received detailing were more likely to dispense ORS and zinc compared to those who were not. Exposure to a mass media campaign in focal states also resulted in higher ORS and zinc coverage.
