What is a PSO?
In response to rising health care costs and increasing concerns about the quality of health care delivery in the United States, the Department of Health and Human Services instituted the Patient Safety and Quality Act of 2005 to encourage healthcare providers to share outcome and patient safety data without fear of reprisal.
The Final Rule of this Act, which took effect in November 2008, established an implementation mechanism known as a Patient Safety Organization (PSO), through which the objectives of the Patient Safety Act could be achieved. The Agency for Healthcare Research and Quality (AHRQ) was designated to administer the provisions of the Patient Safety Act and oversee the approval and operations of PSOs.
