Legend: *Case Mix Groups (CMG) are aggregates of acute care inpatients with similar resource utilization; the Canadian Institute of Health Information developed CMG for use until 2007 when an enhanced version (CMG+) was introduced.

FP = family physician, GIM = general internal medicine, IM = internal medicine, COPD = chronic obstructive pulmonary disease, AMI = acute myocardial infarction.
