Note: Reading Row one as example, of the 2,824 individuals in category (A1), 44.8% were identified with back pain events in only the Office-Based (OB) setting, 1.3% were identified with back pain events in only OutPatient (OP), 2.5% were identified with back pain events in only ER, 9% were identified with only back pain Rx events, and 42.3% were identified with back pain events in more than one, i.e. some combination of OB, OP, ER, and/or Rx back pain events. This table represents adult back pain cases identified in MEPS Panels 5-through-10 Ambulatory Utilization Events files, Office-Based (OB), Outpatient (OP), ER, and Rx, by categories of approximated back pain episodes-of-care groups (N = 8,244).
