HOW CHIA WORKS

How does CHIA collect & check its data?

CHIA collects health care data from payers, providers, and public programs across Massachusetts through standardized submissions. The data undergoes rigorous validation and quality checks before analysis, ensuring accuracy and consistency.

Findings are reviewed internally and, in many cases, shaped by advisory groups of experts, stakeholders, and public health leaders to ensure transparency, relevance, and impact.
