CORRESPONDING AUTHOR: Kevin A. Pearce, MD MPH, Department of Family Practice, and Community Medicine, University of Kentucky College, of Medicine, Rm K-302, Kentucky Clinic, Lexington, KY 40536-0284, kpearce{at}email.uky.edu

BACKGROUND We describe the rationale, methods, and important lessons learned from doing a practice content study in a new practice-based research network (PBRN).

METHODS We performed a modified replication of the National Ambulatory Medical Care Survey (NAMCS) in the Kentucky Ambulatory Network (KAN). Network clinicians had input into focused modifications of the NAMCS protocol, including addition of data fields of special interest to them. Cross-sectional sampling of patient visits was done for a 1-year period, with each practice collecting data during 2 separate weeks. We used selected results to illustrate lessons learned and the value of this endeavor.

RESULTS Twenty-three KAN clinicians helped recruit 33 of their colleagues, and these 56 community-based primary care clinicians collected data on 2,228 office visits. Patient demographics (except race) and the top 10 diagnoses were similar to US NAMCS data. One third of visits addressed 3 or more diagnoses, and one fourth of the visits involved 4 or more medications. The top 10 primary diagnoses represented only one third of all primary diagnoses. Seventy percent of adult patients were either overweight (30%) or obese (40%). Rates of counseling on diet or exercise rose with increases in body mass index.

CONCLUSION This study helped us establish and activate our new PBRN, increasing its membership in the process. The descriptive data gained will stimulate, guide, and support our future research activities.
