CAHPS in practice: the Iowa demonstration.

This article evaluates the usefulness of the Consumer Assessment of Health Plan Study (CAHPS) surveys and reports in a demonstration and evaluation with three health care purchasers in Iowa. The CAHPS survey detected significant differences between health plans in several domains of health care. Both paper- and Web-based consumer reports were developed and distributed to consumers and stakeholders. There was some agreement on the value of these reports, but areas for improvement were noted.
