Assistant Professor and Director of the Community Health Impact Coalition
Dr. Ballard studies the effects of interventions to improve the performance of community health workers in low-income countries and conducts research on methodological issues related to the evaluation of complex social interventions. Her research on the community health worker program optimization practice was recently included in the World Health Organization’s first guideline on community health workers.
Dr. Ballard conducted one of the earliest syntheses of existing guidance concerning the practice of overviews of reviews practice and led the development of a proposed methodological checklist to minimize risk of bias in overviews. This proposed checklist is now being employed by overviews in the Cochrane Database of Systematic Reviews and is recommended by Australia’s National Health and Medical Research Council in their draft guidance on assessing risk of bias.
At Mount Sinai, Dr. Ballard is conducting research and developing knowledge products that will catalyze the adoption of high-impact community health systems design across the community health ecosystem and create an enabling environment for quality. Dr. Ballard is the Director of the Community Health Impact Coalition, a quality of care initiative by practitioners in 15+ countries who are working together to build, test, and scale community health delivery models that serve high-risk populations. Leveraging implementation research, health technology, and model health systems, the Coalition will advocate for and support actionable, evidence-based policy change.
