Executive Summary: A Realist Review of What Works to Improve Data Use for Immunization

The goal of the Immunization Data: Evidence for Action (IDEA) project is to identify, review, synthesize, and disseminate what works to improve the use of immunization data and why it works. In partnership with the Pan American Health Organization, the Health Systems Analytics team at PATH conducted a “realist” systematic review of existing research evidence to answer two principal research questions:

01. What are the most effective interventions to improve the use of data for immunization program and policy decision-making?

02. Why and how do these interventions produce the outcomes that they do?
