Can we join CHPSO even though our hospital is not in California? Does our hospital have to join a PSO?

Since many of its members are outside California, CHPSO in 2015 changed its name from the California Hospital Patient Safety Organization to CHPSO. CHPSO members currently include healthcare organizations in nine states: Arizona, California, Colorado, Hawaii, Nevada, New Mexico, Oregon, Texas, and Washington. As one of the first federally-listed PSOs through the Agency for Healthcare Research and Quality (AHRQ), CHPSO welcomes members from all states and US territories. Details about CHPSO benefits and pricing are available on the CHPSO website by clicking here.

In terms of joining a PSO, the Centers for Medicare and Medicaid (CMS) finalized the PSO requirements for January 1, 2017 for hospitals of greater than 50 beds contracting with a Qualified Health Plans (QHPs), restricting QHPs from contracting with them unless the hospital either:

(i)(A) Utilizes a patient safety evaluation system [for reporting to a PSO] as defined in 42 CFR 3.20; and (B) Implements a mechanism for comprehensive person-centered hospital discharge to improve care coordination and health care quality for each patient; or

(ii) Implements an evidence-based initiative, to improve health care quality through the collection, management and analysis of patient safety events that reduces all cause preventable harm, prevents hospital readmission, or improves care coordination.

If a hospital chooses to take route (ii), hospitals do not have the benefits of PSO participation, such asthe Patient Safety Work Product (PSWP) privilege, safe tables and feedback on events and reports. For more details or to set up an appointment with a CHPSO team member, please contact
