Lessons Learnt during the Implementation of WISN for Comprehensive Primary Health Care in India, South Africa and Peru.

While India and South Africa had unique experiences with the integration of WISN in their health system, none of the countries has yet benefited from the implementation of WISN due to financial, infrastructure and technical challenges. Since the methodology developed by the Peruvian Ministry of Health is context-specific, its implementation has been promising for health workforce planning. The learnings from these countries' experiences will prove useful in bringing future changes for the health workforce.
