It was a data treasure trove promising answers to a question asked by health consumers everywhere: Which doctors, clinics and hospitals deliver the best care for the best price? But Utah's All-Payer Claims Database, a repository of all medical and pharmacy insurance claims filed statewide, has failed to deliver. State Department of Health employees charged with building and overseeing the database have moved on to other positions in state government. The New Jersey-based vendor hired to mine the data, Care Advantage, went out of business last month. And promised reports comparing health centers on certain quality measures have yet to materialize.
