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.

The table below highlights the types of procedures done at the Cedars-Sinai Orthopaedic Center in terms of the categories defined above:
