Measuring Quality of Care and Outcomes for Patients Undergoing Stroke Prevention Procedures

At the Cedars-Sinai Department of Neurosurgery, two procedures are used to correct a narrowing of the carotid artery that can lead to a stroke:

  • Carotid endarterectomy, in which the build up of fatty plaque inside the carotid artery is removed
  • Carotid stenting is a non-surgical procedure, a catheter-based procedure, used to prevent stroke, by correcting stenosis (narrowing) in the common carotid artery.

In its ongoing commitment to improving the quality of care and outcomes for patients receiving treatment, the Department of Neurosurgery monitors:

  • The volume of each type of procedure done
  • The average length of stay in the medical center required for each type of procedure
  • Mortality rates for patients up to 30 days after their discharge from the medical center following each procedure.

The graphs below reflect volumes, average lengths of stay and mortality rates for carotid endarterectomies and carotid stenting procedures done at Cedars-Sinai. The data are from the University HealthSystem Consortium (UHC), an alliance of 120 academic medical centers and 3001 of their affiliated hospitals representing the nation's leading academic medical centers.  The majority of these facilities participate   in UHC's Clinical DataBase/Resource Manager. The data were assessed on April 27, 2014 for patients discharged January 1, 2011 - December 31, 2013.


Carotid Endarterectomy Procedures

The graph below shows the total number of carotid endarterectomy procedures performed at Cedars-Sinai Medical Center for the past 3 years.

The following graph compares the observed (actual) numbers of days a patient undergoing a carotid endarterectomy stayed at Cedars-Sinai Medical Center with the number of days that a patient of the same gender and age with a similar diagnosis, procedure and complications would be expected to stay in the hospital. 

A lower observed length of stay is better than a higher one.

The following graph compares the actual percentage of patients undergoing a carotid endarterectomy who died before being discharged from Cedars-Sinai Medical Center from the percent of expected deaths for patients of the same age and gender with a similar diagnosis, procedure and complications.    

A lower observed mortality rate is better than a higher one. At Cedars-Sinai Medical Center, there were no deaths following carotid endarterectomies done in 2011, 2012 or 2013.  

    

Carotid Stenting Procedures

The graph below shows the total number of carotid stenting procedures performed at  Cedars-Sinai Medical Center during the past 3 years.

 

The following graph compares the observed (actual) numbers of days a patient undergoing a carotid stent procedure stayed at Cedars-Sinai Medical Center with the number of days that a patient of the same gender and age with a similar diagnosis, procedure and complications would be expected to stay in the hospital. 

A lower observed length of stay is better than a higher one.

 

The following graph compares the actual percentage of patients undergoing a carotid stent procedure who died before being discharged from Cedars-Sinai Medical Center from the percent of expected deaths for patients of the same age and gender with a similar diagnosis, procedure and complications. 

A lower observed mortality rate is better than a higher one. At Cedars-Sinai, there were no deaths following carotid stenting procedures done between 2011 and 2013.
