↵a Type 1 nuances: separate floors or same floor, both options (same floor preferred, if not available other floor), another location. Type 2 nuances: all providers/staff in one space; some providers in one space with medical assistants separate; teams organized into pods.
↵b Existing space is defined as clinic existing prior to integration efforts commencing, with only minor changes to accommodate new model of care delivery.
↵c Where the new clinician sees patients.
↵d Variable (primary, same floor; backup, separate locations).
