Measuring the Quality of Orthopaedic Care at Cedars-Sinai

The Cedars-Sinai Orthopaedic Center continually monitors the care it provides to patients. Several factors are measured:

  • Total volume of procedures. Studies suggest that for many surgical procedures, hospitals that perform high volumes have better quality outcomes, i.e. lower short-term and long term mortality and morbidity. Volume is an indicator of experience, which influences outcomes in multiple ways. In addition to the experience of surgeons in performing specific procedures, high volume hospitals may institute specific care processes that improve outcomes and have the infrastructure dedicated to particular clinical specialties, including related technology and intensive care personnel. Commitment to quality standards throughout the institution is also an important determinant of better outcomes.1,2 In addition, outcomes for high-risk procedures have been shown to be better when performed by more highly-trained surgeons than by general surgeons.3
  • The percentage of procedures that are performed on an outpatient basis. When a procedure can be done on a outpatient basis, the patient tends to heal more quickly with less pain and less interference with his or her daily activities.
  • Average length of stay (ALOS): This refers to the average number of days a patient stays at Cedars-Sinai Medical Center after being admitted. The goal is to ensure that all patients are appropriately treated in the hospital for their respective conditions, and are not hospitalized longer than they need to be.
  • Surgical Site Infections.  A surgical site infection is an infection that occurs after surgery, in the part of the body where the surgery was performed. Many such infections involve the skin only, but some are more serious and in tissues under the skin or in an organ.  These are called deep incisional and organ/space surgical site infections.  We measure our performance by tracking the observed vs. expected rate of infection, as calculated by the California Department of Public Health and the Centers for Disease Control and Reporting National Healthcare Safety Network.  To learn more, and view Cedars-Sinai performance for hip and knee replacement surgeries, click on the links below.
