Improving the quality of preventive cardiovascular care provided by primary care physicians: insights from a US Quality Improvement Organization

Background. During 2000-03, Qualidigm, a US Quality Improvement Organization, conducted a project to improve the care received by elderly Medicare patients with coronary artery disease or cardiovascular risk factors. Methods. We recruited primary care physicians in private practice in the state of Connecticut. Then, we identified approximately 30-50 patients per physician from the periods 1 January 2000 to 31 December 2000 and 1 November 2001 to 31 October 2002. We abstracted medical records to assess processes and outcomes of care, and we provided the physicians with performance data and a variety of practice-enhancing materials. The physicians utilized those materials that they perceived to be most helpful. Results. We identified and recruited 974 primary care physicians to participate. Of these, 103 (10.6%) committed to participate, and 85 of the 103 completed the project. Among the intervention tools, physicians and their office personnel utilized personal digital assistants (PDAs) (36.5%) and patient education materials (34.1%) most commonly. Overall, quality of care improved for most physicians (mean quality score 62.0 to 67.8%, P < 0.001). However, not all improved, and most improvements were modest [mean absolute improvement in quality score 5.8%, standard deviation (SD) 6.8%]. Conclusions. Quality Improvement Organizations and others interested in improving outpatient quality of care face significant challenges in recruiting self-employed primary care physicians to quality improvement projects and in bringing about transformational change. Future primary care quality improvement projects should include careful assessments of practice-specific barriers, interventions that are linked to these barriers, and support of the practices on implementation.
