The Collaborative Ohio Inquiry Network (COIN) is a PBRN learning community that develops the capacity of PBRNs for research, conducts high-impact practice-based research, and translates research into practice.

COIN’s PBRNs include more than 277 primary care practices and 1,967 clinicians. Together, these PBRNs have conducted 144 externally-funded and 60 internally-funded studies, supported by over $47 million in external funding. The networks have generated 167 peer-reviewed research publications. They have a history of collaboration with each other on specific studies, and of partnership with other PBRNs around the country.
