Cassatt Patient Safety Organization Voluntarily Relinquishes Status: Implications for Patient Safety Data and Federal Oversight

On June 8, 2026, the Cassatt Patient Safety Organization, identified as PSO number P0136, formally relinquished its status as a federally recognized Patient Safety Organization. This voluntary action, announced by the Department of Health and Human Services' Agency for Healthcare Research and Quality (AHRQ), necessitates a structured process for the disposition of sensitive patient safety information and highlights the critical regulatory mechanisms designed to safeguard healthcare data integrity and promote patient safety.

The Role of Patient Safety Organizations

Patient Safety Organizations were established under the Patient Safety and Quality Improvement Act of 2005 (Patient Safety Act) and its implementing Patient Safety and Quality Improvement Final Rule (Patient Safety Rule), codified in 42 U.S.C. 299b-21 to 299b-26 and 42 CFR part 3. The primary mission of PSOs is to foster a culture of open reporting and analysis of medical errors and adverse events without fear of legal discovery. They achieve this by creating a secure environment where healthcare providers can voluntarily submit "patient safety work product" (PSWP) on a privileged and confidential basis.

This framework is designed to encourage healthcare providers to identify and learn from safety incidents, ultimately improving the quality of care and reducing medical errors. AHRQ, on behalf of the Secretary of HHS, is responsible for listing and overseeing these organizations, ensuring they meet the statutory and regulatory requirements.

The Delisting of Cassatt Patient Safety Organization

The delisting of a PSO can occur for several reasons: voluntary relinquishment, failure to meet the ongoing requirements of the Patient Safety Act and Rule, or expiration of its listing. In Cassatt PSO's case, the delisting resulted from a notification of proposed voluntary relinquishment. This is not an unusual occurrence within the PSO program, as organizations may change their strategic focus or operational capacity.

The official delisting of Cassatt PSO became effective at midnight ET on June 8, 2026. This action means Cassatt no longer holds the federal protections and responsibilities associated with PSO status. AHRQ, as the administering agency, provides public notice of such delistings, maintaining transparency in the program and keeping stakeholders informed about the active roster of PSOs.

Handling of Patient Safety Work Product

One of the most critical aspects of any PSO delisting, especially voluntary relinquishment, is the proper management of Patient Safety Work Product (PSWP) collected during the organization's active period. The Patient Safety Rule, specifically section 3.108(c)(2)(i) and (ii), mandates that a delisted PSO must notify the healthcare providers who reported to it and ensure the disposition of PSWP consistent with section 3.108(b)(3).

Under section 3.108(b)(3), a delisted PSO is given a 90-day window from the effective date of delisting to complete the appropriate disposition of all PSWP in its possession. This crucial step ensures that the confidentiality and privilege protections afforded to this sensitive information are maintained, even after the PSO ceases its official operations. The proper handling prevents unauthorized disclosure and safeguards the trust placed in the PSO system by healthcare providers.

Broader Implications for Patient Safety and Data Confidentiality

The delisting of Cassatt PSO, while a routine administrative action in some respects, serves as an important reminder of the integrity of the federal PSO program. The program's effectiveness hinges on the assurance that data reported by providers remains protected. Any failure in this regard could undermine confidence and discourage future reporting, thereby jeopardizing the overarching goal of improving patient safety.

For healthcare providers who previously reported to Cassatt PSO, the notification process and proper disposition of PSWP are vital. They need assurance that their voluntarily submitted safety information will continue to be handled with the highest degree of confidentiality and privilege. This event also reinforces AHRQ's ongoing commitment to administering the Patient Safety Act and Rule rigorously, ensuring that all PSOs, both active and those undergoing delisting, adhere to the established standards. The public availability of PSO directories, including information on delisted entities, further demonstrates this commitment to transparency and accountability in the national effort to enhance healthcare quality.
