Evaluating the Impact of Interoperability on Healthcare Outcomes: Pilot Study
February 21, 2017 — 10:00AM EST - 05:00PM EST
The DoD/VA Interagency Program Office (IPO) led a pilot study to develop a metric, based on clinical outcomes, that can help quantify the benefits of interoperability between the DoD and VA healthcare systems. The enterprise data repositories of the DoD and VA were queried for hemoglobin A1C results, diagnoses, and anthropometric data. The availability of shared data was positively associated with fewer redundant A1C screening tests. This suggests that clinicians are viewing shared data and using it to improve adherence to diabetes screening guidelines. This proof of concept demonstrated a repeatable process of generating and testing new outcome-oriented metrics between the DoD and VA healthcare systems.
Understand how DoD and VA are approaching outcome-oriented metrics for interoperability-related health outcomes. Lessons learned from this study are benefiting subsequent DoD/VA use case analyses.
Quantify the proportion of shared patients receiving redundant A1C screening tests. Analysts may consider evaluating the trend - over time and a larger population - of use case-specific measures similar to this one in anticipation that the percentage would drop with improvements to interoperability.
Associate prior DoD A1C screening results with fewer subsequent VA A1C screening lab tests. Using clinical best practice guidelines as a basis for targeted analysis of the patient population data enables the inference of an impact of interoperability on the decision to order an A1C lab test.
