The study team working on the PCORI application for comparative effectiveness study of surgical interventions selected 18 sites to participate in the grant application. Nearly all of the sites were selected from current participants in CPRN. Below are the site principle investigators (PIs) and the institutions that have been selected. All sites are actively working on completing site specific aspects of their participation in the study if it is funded by PCORI. The application is due to PCORI on July 31, 2015.
