Immunization Data: Evidence for Action. A Realist Review of What Works to Improve Data Use for Immunization

The IDEA review is a global synthesis of existing evidence aimed at increasing the use of high-quality data to improve immunization coverage.

The goal of the 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 PAHO, the Health Systems Analytics team at PATH conducted a “realist” systematic review of existing research evidence to determine what are the most effective interventions to improve the use of data for immunization program and policy decision-making; and why and how these interventions produce the outcomes that they do.

The IDEA review draws on nearly 550 documents including published literature, working papers, project evaluations and reports, which were distilled and prioritized by global immunization experts.
