Diabetes care in the U.S. consistently fails to meet recommended quality standards. Barriers impede the translation of evidence-based guidelines into sustainable practice. Few studies have considered multiple barriers, and there is a lack of evidence-based strategy in choosing interventions to overcome barriers. This study involves a comprehensive assessment of practice barriers to diabetes guidelines adherence across a primary care network. The BAT based upon a framework proposed by Cabana, et al (1999) will be validated to correlate with provider and practice adherence to diabetes care guidelines. A Diabetes Flow Sheet implemented in our Network to track adherence to guidelines will be assessed and correlated with measured barriers. This organizational strategy will support an evidence-based approach to quality initiative interventions. The BAT will be administered to practice team members: providers, support staff, and practice managers in our Network of 25 primary care practices. Five hypotheses are tested:
