The Agency for Healthcare Research and Quality (AHRQ) has published a notice regarding Patient Safety and Quality Improvement Act of 2005 reporting requirements. By way of background, the Act authorizes Patient Safety Organizations (PSOs) to collect and analyze confidential patient safety information reported by healthcare providers. AHRQ has coordinated the development of a set of common definitions and reporting formats to facilitate the voluntary collection of the patient safety data and reporting of this information to PSOs. The agency invites public input on the initial common formats and describes its process for developing future versions.
