CDN is dedicated to providing and improving comprehensive and accessible community-oriented primary and preventive health services for underserved populations. CDN provides clinicians with the opportunity to conduct clinical research in their practices, which provides their patients with the means to access high quality evidenced-based care in their neighborhoods. This enables access to care that otherwise would be restricted to tertiary care sites, universities, and other research centers.

CDN has over 25 years of experience developing, conducting, implementing and evaluating practice- based research with Community Health Centers (CHCs) and other safety net practices. Clinical research conducted by CDN at member sites covers a wide range of prevention and treatment studies involving conventional medical therapies, behavioral interventions, as well as integrative/complementary/alternative health practices.

N2 PBRN: Building a Network of Safety Net PBRNs

CDN was recently designated an AHRQ Center of Excellence in Primary Care-Practice Based Research and Learning (Grant No. 1 P30-HS-021667; PI JN Tobin) and was designated the lead PBRN in a network of networks N2 PBRNN2 PBRN is a network of networks that includes nine established PBRNs. Together, N2 PBRN covers 16 states, and includes nearly 200 active research-engaged practices, both urban and rural, from a network of over 600 practices. This represents over 2,700 Full Time Employed (FTE) physicians, 1,750 FTE nurses, nearly 2,500 FTE other medical personnel, and a combined patient population of 4.2 million. The goal of N2 PBRN is to strengthen the research and dissemination infrastructure of each collaborating PBRN by creating an enduring infrastructure to:

  1. Accelerate the generation of new clinical knowledge
  2. Build a community of learning for primary care practices to improve quality, patient safety and effectiveness of care by implementing new clinical knowledge into practice
