The NEJM speculates in an editorial:
Ultimately, the payment of primary care physicians might be a blend of fee for service, monthly fees for practices serving as patient-centered medical homes, and additional bonuses for meeting quality and efficiency performance goals. Primary care physicians could instead be paid a monthly fee per patient (adjusted for the case mix), along with a bonus for performance. Such payment methods are more likely to be acceptable to physicians than is global capitation, because they do not put physicians at risk for services provided by others, and they contain only positive performance bonuses.
