This project seeks to advance knowledge about how non-financial incentive structures can be designed to generate improvements in the allocation of resources devoted to primary and secondary prevention, with the overall goals of improving population health and reducing health system costs. Sue Mavedzenge, representing RTI, is an infectious disease epidemiologist, who has lived and worked in Zimbabwe for many years. Sue will play a critical role in the study design, trial implementation and monitoring, and analysis and interpretation of study results.
