Making the case
One little number explains quite a bit about DHMC's patient population. The number is the case mix index (CMI) and it reflects the diversity, clinical complexity, and need for resources among the patient population at a certain hospital. A hospital with a high CMI has a greater variety of cases, sicker patients, and a need for more equipment. For FY2010, DHMC's CMI, 2.13, ranked in the top 3% nationally—96th out of 3,594 hospitals. The chart below shows CMIs for various hospitals and medical centers across the U.S. For more about DHMC's case mix index, see "CMI offers a case in point" in the Fall 2011 issue of Dartmouth Medicine.
