Impact studies examine the impact of a novel system alignment strategy on relevant measures of health and well-being for affected populations. These studies build on pilot studies confirming the feasibility and acceptability of the systems alignment strategy and use rigorous research methods to evaluate the impact on measures of health and health equity. As of 2019, Impact studies receive up to $500,000 in total funding to be used over a 36-month period to study the impact of a proposed system alignment strategy. Prior to 2019, Impact studies received up to $250,000 in total funding to be used over a 24-month period.
