Groundbreaking original research developed by the Kansas Health Information Network (KHIN) and Diameter Health now demonstrates the incontestable value health information exchanges deliver by aggregating patient data across all healthcare providers into a longitudinal patient view.

Data gathered in the 2016-17 study validates the strategy promoted by MACRA/QPP to establish Qualified Clinical Data Registries (QCDRs) as new organizations which compute quality measures across providers. The study highlights the importance of using longitudinal patient data from providers to improve the accuracy and completeness of quality reporting. The research presents data from the KHIN health information exchange on primary care practices where more than 50,000 patients visited 214 separate care sites during the measurement period.

“This new research supports the use of health information exchange data in the computation of quality measures,” said Laura McCrary, Ed.D, executive director of KHIN. “Our research findings indicate quality measure calculation is possible using interoperability standards to collect near real-time clinical data from disparate electronic health records (EHRs).”

She added, “KHIN can now compute quality measures across all providers treating a patient, resulting in higher quality scores for providers and a more accurate, patient centric view of the quality of care provided. This is in stark contrast to the current model which computes quality measures from only the data in the provider’s EHR. Patients receive care from many different providers and this research suggests a more accurate assessment of the quality of care provided to a patient can be computed by using health information exchange data.”

Diameter Health CEO Eric Rosow, said, “The research results demonstrate how normalized, multi-sourced clinical data fuels a myriad of applications across the new healthcare ecosystem. The outcomes support Quality reporting, value-based care and population health initiatives, and will contribute standard supplemental data for Payer HEDIS and Stars reporting.”

McCrary and John D’Amore, President and Chief Strategy Officer of Diameter Health, will discuss the research study as part of their presentation, “QPP/MIPS Success With Longitudinal Quality Measurement” at HIMSS 2018 Annual Conference on Friday, March 9, from 12-1:00 p.m. in the Las Vegas - Venetian Convention Center.

The session examines Quality measures calculated using data from primary care practices’ own EHRs and compares this with quality measures computed from the data in the KHIN health information exchange. The speakers demonstrate that complete clinical information is essential to accurately calculate both process measures, such as preventive screening, and care outcomes measures.
