RESUMO
OBJECTIVES: Although team-based care can improve coronary heart disease (CHD) risk factors and is considered cost-effective from a healthcare system perspective, little is known about the financial impact of team-based primary care for secondary prevention of CHD. The purpose of this study was to define the impact of team-based care for CHD on utilization, costs, and revenue of a private primary care practice. STUDY DESIGN: Interrupted time series analysis. METHODS: Between March 1, 2010, and March 31, 2013, we assisted a private medical practice, comprising 5 primary care clinic sites, to organize and deliver team-based care for patients with CHD. We used billing records and the registered nurse care manager's diary to calculate the cost of team-based care, differences in the average number of visits per patient, and revenue per patient before and after the implementation of team-based care. RESULTS: The net cost of team-based primary care was $291 per patient over the 1-year period of observation. CONCLUSIONS: The findings from this study are consistent with other economic analyses of team-based care and suggest that payment for care must be restructured if patients are expected to enjoy the benefits of team-based primary care.
