SUPPLEMENTARY INFORMATION: emcdonald on DSK67QTVN1PROD with NOTICES Background The Patient Safety Act authorizes the listing of PSOs, which are entities or component organizations whose mission and primary activity is to conduct activities to improve patient safety and the quality of health care delivery. HHS issued the Patient Safety Rule to implement the Patient Safety Act. AHRQ administers the provisions of the Patient Safety Act and Patient Safety Rule (PDF file, 450 KB. PDF Help) relating to the listing and operation of PSOs. The Patient Safety Rule authorizes AHRQ to list as a PSO an entity that attests that it meets the statutory and regulatory requirements for listing. A PSO can be ‘‘delisted’’ if it is found no longer to meet the requirements of the Patient Safety Act and Patient Safety Rule, or when a PSO chooses to voluntarily relinquish its status as a PSO for any reason. Section 3.108(d) of the Patient Safety Rule requires AHRQ to provide public notice when it removes an organization from the list of federally approved PSOs. AHRQ has accepted a notification from the Northern Metropolitan Patient Safety Institute, PSO number P0021, which is a component entity of Northern Metropolitan Hospital Association, to voluntarily relinquish its status as a PSO. Accordingly, the Northern Metropolitan Patient Safety Institute was delisted effective at 12:00 Midnight ET (2400) on May 29, 2013. Northern Metropolitan Patient Safety Institute has patient safety work product (PSWP) in its possession. The PSO will meet the requirements of section 3.108(c)(2)(i) of the Patient Safety Rule regarding notification of providers that have reported to the PSO. In addition, according to section 3.108(c)(2)(ii) of the Patient Safety Rule regarding disposition of PSWP, the PSO has 90 days from the effective date of delisting and revocation to complete the disposition of PSWP that is currently in the PSO’s possession. More information on PSOs can be obtained through AHRQ’s PSO Web site at https://www.pso.AHRQ.gov/ index.html. Dated: June 21, 2013. Carolyn M. Clancy, Director.
