Measurement and Inference in the Equity of Specialized Pediatric Healthcare

PI’s: Julie Swann & Nicoleta Serban

Aim 1: Quantify the access to healthcare for pediatric patients, including access to specialized care.  
Aim 2: Identify measures of healthcare quality for high-impact pediatric conditions.
Aim 3: Evaluate and explain inequities in the healthcare measures geographically and for subpopulations like Medicaid-eligible children including identifying areas of significantly positive or negative outcomes.

Equity is the absence of systematic disparities in healthcare delivery (e.g., access, quality, cost and outcomes) between groups of people.  Access has many elements including distance and resources for healthcare. This seed grant initiated our first detailed examination of equity in access across the state of Georgia, and it laid the foundation for a number of other ongoing studies.
