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. An average hospital scores 1.0 on the index.

UC's patients generally have more complex medical conditions, which often can be managed only in tertiary referral hospitals like UC hospitals, than patients at other hospitals.

UC medical centers must balance their role as a safety net with the need to treat patients with highly advanced medical conditions that require state-of-the-art equipment and technology.
