The Government Accountability Office (GAO) has issued a report entitled "Electronic Personal Health Information Exchange: Health Care Entities' Reported Disclosure Practices and Effects on Quality of Care." The report, which was required by the HITECH Act, reviews practices implemented by health information exchange organizations, providers, and other health care entities that disclose electronic personal health information, based on case studies of operational health information exchanges and a selection of each of the exchanges’ participating providers. The health care entities reported that they implement widely-accepted practices for safeguarding personal information to help ensure the appropriate use and disclosure of electronic personal health information for treatment purposes. In addition, both the exchanges and providers reported examples of ways that sharing electronic personal health information has had a positive effect on the quality of care that providers deliver to patients.
