To the Editor: Dr McCormick and colleagues1 report that health maintenance organizations (HMOs)
that had low Health Plan Employer Data and Information Set (HEDIS) scores
were more likely to stop disclosing their quality data. They state that most
plans are not publicly reporting information regarding treatment outcomes
and decisions, when in fact the overwhelming majority of them do. The authors'
conclusion is based only on data from 1997 to 1999. I am puzzled that they
did not include the most recent data, given that the latest information from
2001 shows that health plans representing 95% of managed care enrollees now
publicly disclose their HEDIS scores.2
