The document summarizes new cardiac surgery programs at the University of Arizona Medical Center (UAMC) including minimally invasive and robotic techniques. It discusses implementation frameworks focusing on team development and metrics of success. Outcomes data shows the new programs achieved lower mortality and morbidity rates compared to national benchmarks. The programs increased hospital volume and referrals while improving patient satisfaction. The summary focuses on the high level information around new programs, implementation strategies, outcomes data, and business impacts.

21. Metrics of Success: Robotic Mitral Valve
• SAFETY: Composite morbidity/mortality do not exceed 10%
• COSTS: No greater than 25% increase over conventional cases
• SATISFACTION:
– Staff: “Culture of safety”1
survey results do not decline by more than 5%
– Patients: Patient satisfaction exceeds the results for conventional cases
• EFFECTIVENESS:
– 90% repair rate
– 90% freedom from reoperation at 1 year

34. Redefining Value
(in the era of patient centered care)
1. Clinical outcomes
2. Cost-effectiveness
3. Quality of life
4. If less-invasive is not inferior,
then it is superior.
