When compared with the average for all California medical centers and hospitals, UC medical centers treat more complicated cases. The difference has grown during the past seven years.

The "Case Mix" Index is a standard hospital metric for addressing the question: "How sick are our patients?" Hospitals with more seriously ill patients score higher on the index, which translates into more resources used by the hospital and higher cost. A patient of average complexity scores 1.0 on the index. The index has been rising at each of the medical centers, reflecting growth in highly complex care including complex surgical cases and transplants.

The patient mix at the UC medical centers reflects that the centers act as tertiary referral hospitals that often serve sicker patients and those with the most complex cases. As noted earlier, they treat critically ill newborns, care for cancer patients, and treat half of all transplant patients and one-quarter of extensive burn cases in California.
