More health plans withholding NCQA data

The number of health plans refusing to allow the Washington, DC-based National Committee for Quality Assurance (NCQA) to release data on 50 performance measures rose sharply in 1998, Knight-Ridder/Tribune News reports.

Nationwide, 292 health plans reported data measured as part of the Health Employer Data Information Set (HEDIS), the article states.

HEDIS measures are used to measure health plan performance in a variety of areas—such as vaccination rates for patients younger than 2 years old, and mammogram screening rates among health plan members. About 155 other plans gave data to NCQA, but would not allow the information to be released. That number compares with 41 plans that did not want their data released for public consumption last year.

Typically, those withholding their data performed worst on almost every measure than plans that allowed their data to be released, the article states.
