Using a Multicountry Learning Network to Harvest and Rapidly Spread Implementation Knowledge across Programs Aimed to Reduce Mother-to-Child Transmission of HIV and Improve Nutrition: Perspectives and Lessons Learned for Similar Large-Scale Initiatives.

As countries pursue UNAIDS's 90-90-90 target for ending the AIDS epidemic, success is dependent on learning how to deliver effective care. We describe a learning network and mechanisms used to foster communication and sharing of ideas and results across 6 countries in the Partnership for HIV-Free Survival. The network used 2 forms of peer exchange, in-person and virtual, and a variety of knowledge management mechanisms to harvest and spread key learning. Key learning included valuable insights on how to design and convene a multicountry learning network, including top enablers of success and practical insights on the network's value. The network was instrumental in accelerating learning about improving care. Our experience shows the value of creating a quality improvement-driven, multicountry learning network to accelerate the pace of improving care systems. Government ownership and adaptation of collaborative learning efforts to the country context must be considered when designing future networks.
