A1 Neale, Anne Victoria YR 2011 UL http://www.jabfm.org/content/24/5/481.abstract AB We have quite a rich issue this month related to practice-based research networks (PBRNs)—reflections on where they have been, where they should go, how they should happen; lessons learned about recruiting physicians and patients and new research methods; and several clinical studies from existing PBRNs. We had an amazing number of manuscripts submitted this year for the PBRN issue; as a result, this is a powerful issue. Some are under revision for future issues of the Journal of the American Board of Family Medicine, just as we have some articles from PBRNs appearing in most issues. PBRNs have deepened the family medicine research tradition. The importance of primary care research to build the evidence base of our clinical practice, plus the useful work building the methods of primary care research, distinguishes the pioneers in PBRNs. PBRNs are Health Improvement Networks and national treasures to be nurtured.
