The clinical care domain measures clinical care quality predominantly by using mortality measures. The mortality rate refers to the patient death rate for a specific disease. There are five mortality measures used in this domain (listed here). The sixth measure is the complications rate for the total hip/knee arthroplasty (a.k.a. replacement) procedure:

• MORT-30-AMI: 30-day mortality for patients that have an acute myocardial infarction
• MORT-30-HF: 30-day mortality for patients that have heart failure
• MORT-30-PN: 30-day mortality for patients that have pneumonia
• THA/TKA: The number of THA/TKA procedures with complications
• MORT-30-COPD: 30-day mortality for patients that have COPD
• MORT-30-CABG: 30-day mortality for patients that undergo coronary artery bypass grafting
