VA Captures More Complete Quality Performance Data Compared to Medicare Advantage


BACKGROUND:
Medicare Advantage (MA) plans and the VA healthcare system assess quality of care using standardized Healthcare Effectiveness Data and Information Set (HEDIS) performance measures. However, little is known about the relative accuracy of quality indicators for persons receiving care in more than one healthcare system. Private plans typically generate performance data using insurance claims or abstracted charts, which may fail to capture the entirety of a patient's care compared with VA's comprehensive electronic health record. Investigators in this study examined the agreement between VA and MA quality assessments for a group of dually-enrolled Veterans, testing the hypothesis that private health plans under-report quality of care relative to a fully integrated delivery system utilizing a comprehensive electronic health record. The number of Veterans sampled for measurement by both systems in the same year (2008 or 2009) ranged from 249 for cholesterol control among Veterans with coronary heart disease to 600 for HbA1c testing among Veterans with diabetes.

FINDINGS:

  • Despite assessing the same Veterans using identical performance measure specifications, reported VA performance was significantly better than reported MA performance for all 12 HEDIS measures. For example, VA's performance advantage ranged from 10 percentage points (46% for VA vs. 36% for MA) for HbA1c <7.0% in diabetes to 55 percentage points (80% for VA vs. 25% for MA) for blood pressure <140/90mmHg in diabetes.
  • In sensitivity analyses limited to Veterans having at least 10 MA outpatient encounters, VA reported better performance than MA for 11 of 12 measures – ranging from 10 percentage points to 36 percentage points.
  • The overall agreement between VA and MA HEDIS assessments ranged from 39% to 63%. Performance rates derived from VA and MA aggregate data were 2 percentage points to 14 percentage points higher than those reported by VA alone.

IMPLICATIONS:

  • Findings suggest that neither Medicare Advantage plans nor VA fully capture quality of care information for dually-enrolled Veterans. However, VA captures significantly more information than MA. This may be attributable to VA's system-wide electronic health record that allows for more complete capture of quality information across multiple providers and settings.

LIMITATIONS:

  • Investigators did not validate reported performance rates from either healthcare system.

What are HSR&D Publication Briefs?

HSR&D requires notification by HSR&D-funded investigators about all articles accepted for publication. These journal articles are reviewed by HSR&D and publication briefs or summaries are written for a select number of articles that are then forwarded to VHA Central Office leadership to keep them informed about important findings or information. Articles to be summarized are selected by HSR&D based on timeliness of the findings, interest of leadership, or potential impact on the organization. Publication briefs are written for only a small number of HSR&D published articles. Visit the HSR&D citations database for a complete listing of HSR&D articles and presentations.
