A required resource for anyone involved in collecting, calculating or submitting HEDIS data, Volume 2 features the complete technical specifications for each measure. It also includes general guidelines for data collection and reporting, detailed instructions about how to perform the necessary calculations and guidelines for sampling.
HEDIS is the gold standard in health care performance measurement, used by more than 90 percent of the nation's health plans and many leading employers and regulators. HEDIS is a set of standardized measures that specifies how organizations collect, audit and report performance information across the most pressing clinical areas, as well as important dimensions of customer satisfaction and patient experience.
HEDIS Volume 2 incorporates the following additional content, providing added value to our customers:
Rules for Allowable Adjustments of HEDIS: Recognizing that HEDIS measures have traditionally been specified for health plan reporting, and that the industry desires to apply the measures to different levels of the health care system to facilitate, for example, population health management and development of quality improvement programs and initiatives, NCQA incorporated the Rules for Allowable Adjustments of HEDIS (the "Rules") into HEDIS Volume 2 alongside applicable HEDIS measures and specifications. The Rules describe an approach and prescribe guidelines for adjusting NCQA's HEDIS measure specifications for use with other populations. The Rules were reviewed and approved by NCQA measure experts and provide room for evaluating alternate populations without changing the clinical intent of the measure through removal of continuous enrollment or product-line criteria, for example.
