Estimating the Costs of Implementing Comprehensive Primary Care: A Narrative Review.

The performance of the any health-care system relies on a high-functioning primary care system. Increasing primary care practices' adoption of "comprehensive primary care" capabilities might yield meaningful improvements in the quality and efficiency of primary care. However, many comprehensive primary care capabilities, such as care management and coordination, are not compensated via traditional fee-for-service payment. To calculate new payments for these capabilities, policymakers would need estimates of the costs that practices incur when adopting, maintaining, and using the capabilities. We performed a narrative review of the existing literature on the costs of adopting and implementing comprehensive primary care capabilities. These studies have found that practices incur significant costs when adopting and implementing comprehensive primary care capabilities. However, the studies had significant limitations that prevent extensive use of their estimates for payment policy. Particularly, the strongest studies focused on a small numbers of practices in specific geographic areas and the concepts and methods used to assess costs varied greatly across the studies. Furthermore, none of the studies in our review attempted to estimate differences in costs across practices with patients at varying levels of complexity and illness burden which is important for risk-adjusting payments to practices. Therefore, due to the heterogeneous designs and limited generalizability of published studies highlight the need for additional research, especially if payers wish to link their financial support for comprehensive primary care capabilities to the costs of these capabilities for primary care practices.

Performance on Electronic Clinical Quality Measures in the Comprehensive Primary Care Initiative.

Electronic clinical quality measures (eCQMs) that capture data from electronic health records promise accurate and timely measurement, but their use has been limited in payment. The Comprehensive Primary Care initiative sponsored by the Centers for Medicare & Medicaid Services used eCQMs as part of a shared savings incentive. To assess performance, the authors developed benchmarks for 11 measures and compared performance of initiative and benchmark practices. Initiative practices outperformed benchmark practices on 8 measures in 2015 (between 6.3 and 17.7 percentage points) and 9 measures in 2016 (between 1.7 and 20 percentage points). Initiative practices improved significantly on 7 measures from 2015 to 2016 (between 3.3 and 8.6 percentage points). For 3 measures, the improvement was greater than benchmark practices that reported the same measures in a 2-year period (between 1 and 8.9 percentage points). The authors conclude that eCQMs can be used for payment.
