Measuring the Value-Functions of Primary Care: Provider Level Continuity of Care Measure

This is a process measure evaluating primary care physicians; for each physician, their denominator is all of the patients they saw during the evaluation period who had at least 2 PCP visits (could include visits to other PCPs), and the numerator is the number of those patients whose Bice-Boxerman Continuity of Care Index is >= 0.7.
The Bice-Boxerman index is a validated measure of patient-level care continuity that ranges from 0 to 1; 0 reflects completely disjointed care (a different provider for each visit) and 1 reflects complete continuity with the same provider for all visits.
