Abstract PURPOSE Practices in the 4-year Comprehensive Primary Care (CPC) initiative changed staffing patterns during 2012-2016 to improve care delivery. We sought to characterize these changes and to compare practice patterns with those in similar non-CPC practices in 2016. METHODS We conducted an online survey among selected US primary care practices. We statistically tested 2012-2016 changes in practice-reported staff composition among 461 CPC practices using 2-tailed t tests.
