HEDIS Gap Closure That Holds After the Measurement Year

Fourth-quarter outreach campaigns reliably move HEDIS rates, and just as reliably give back part of the gain the following year. The pattern signals that the gap was closed at the margin rather than at the source.

Durable improvement starts with distinguishing three different failures: the service did not happen, the service happened but was not documented, or the documentation exists but was not captured in a compliant format. Each has a different fix, and outreach only addresses the first.

Supplemental data strategy resolves much of the second and third categories. Standing feeds from health systems, registries, and labs convert clinical reality into measure-compliant evidence without new patient contact.

For genuine care gaps, embed the prompt in the workflow where the decision is made rather than in a separate report. Point-of-care gap lists, standing orders, and pre-visit planning outperform year-end mailings.

Finally, review measure performance monthly with the same seriousness as a financial statement. Quality performance responds to attention cadence more than to campaign intensity.
