Diameter Health Publishes Peer Reviewed Study


Study in Applied Clinical Informatics features client Kansas Health Information Network (KHIN)

Applied Clinical Informatics published “Using Clinical Data Standards to Measure Quality: A New Approach” a peer reviewed article authored by Diameter Health’s John D’Amore, Chun Li, Jonathan Niloff, MD, company advisor Dean Sittig, and Laura McCrary, from the Kansas Health Information Network (KHIN).

The paper evaluates the use of clinical document interchange standards as the basis for quality measurement. Using Diameter Health technology certified by the National Committee for Quality Assurance (NCQA), it identifies and addresses important measurement challenges for seventeen NCQA quality measures.

The study identifies and addresses challenges that affect the use of interoperability standards to measure quality performance by a Qualified Clinical Data Registry (QCDR). The Doctors Quality Reporting Network, offered as part of KHIN, was approved as a QCDR in 2017 by CMS.  KHIN is one of the largest health information exchanges in the nation with over 10,000 providers and almost 6 million patients.

Eric Rosow, CEO of Diameter Health CEO said, “The study published in Applied Clinical Informatics demonstrates the continuing thought leadership and collaboration of our team members, advisors and clients in expanding the horizon of interoperable clinical data standards.   While this work is an outstanding academic achievement, it will also have a practical impact on improving the efficiency and effectiveness of healthcare.”

The immediate beneficiaries of improved data quality are health information exchanges and their members who are able to harmonize data from multiple sources to support member analytic initiatives, and payers who can use the NCQA certified data as standard, supplemental data for HEDIS and STAR reporting. Individual patients will benefit as well as better data quality improves patient care.

Laura McCrary Ed.D of KHIN said, “This study provides the first definitive evidence that quality measures can be calculated across the longitudinal patient data in a health information exchange.  This research is ground breaking and will provide the basis for moving away from provider centric quality measures to patient centric quality measures.   It is truly time that quality metrics evaluate the quality of care that is provided to patients across their entire care team.
