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, a nonsurgical, 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 at Cedars-Sinai required for each type of procedure
  • In-hospital mortality rates for patients from Cedars-Sinai following each procedure

The data shown in the graphs below comes from the University HealthSystem Consortium (UHC), an alliance of more than 300 of the nation’s nonprofit academic medical centers and their affiliated hospitals. The majority of these facilities participate in UHC's Clinical DataBase/Resource Manager.  The majority of these facilities participate   in UHC's Clinical DataBase/Resource Manager. The 2016 data were assessed on Feb. 25, 2017, for patients discharged Jan. 1, 2016-Dec. 31, 2016. Data for prior years was accessed approximately four months after year's end.


Carotid Endarterectomy Procedures

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

The following graph compares the observed (actual) numbers of days a patient undergoing a carotid endarterectomy stayed at Cedars-Sinai 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 with 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. 

  

Carotid Stenting Procedures

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

The following graph compares the observed (actual) numbers of days a patient undergoing a carotid stent procedure stayed at Cedars-Sinai 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 with the percent of expected deaths for patients of the same age and gender with a similar diagnosis, procedure and complications.
