The National Committee for Quality Assurance (NCQA) publishes the an annual report that summarizes results from its Healthcare Effectiveness Data and Information Set. HEDIS is a performance measurement tool for health plans. The State of Health Care Quality Report 2014 (pdf) shows results from calendar year 2013 that were collected from 814 HMOs and 353 PPOs nationwide. The number of Americans enrolled in health plans that report HEDIS data has doubled in 11 years to more than 171 million, or 54 percent of the U.S. population, NCQA said.
Performance remains low in many areas, NCQA reported, adding that too few Americans receive efficient, effective care or recommended tests and treatments. Performance on mental health care and addiction treatment metrics is weakest, NCQA reported. But more children with ADHD are receiving recommended treatment than ever before, a rare highlight amid many poor results on behavioral healthcare measures, the committee said.
