Carotid endarterectomy for elderly patients: predicting complications

Area of Science:

• Vascular Surgery
• Health Services Research
• Medical Quality Improvement

Background:

• Carotid endarterectomy (CE) is a common procedure to prevent stroke.
• Assessing the quality of CE is crucial for patient safety and outcomes.
• Predicting complication rates is essential for informed decision-making.

Purpose of the Study:

• To investigate if hospital and physician structural variables predict complication or death rates after carotid endarterectomy.
• To identify reliable predictors of adverse outcomes following CE.

Main Methods:

• A survey of medical records was conducted for 1302 patients aged 65+ undergoing CE in three US regions.
• Regression analyses controlled for patient condition severity to predict postoperative stroke, heart attack, and 30-day mortality.
• Physician and hospital characteristics were analyzed as potential predictors.

Main Results:

• The overall 30-day complication or death rate was 11.3%.
• Patient demographics, physician volume, board certification, age, and hospital characteristics did not significantly predict outcomes.
• Surgeons graduating from non-Western/Canadian foreign medical schools were associated with a higher complication rate (19.6% vs. 10.4%, P<0.05).

Conclusions:

• Postoperative complication and death rates following carotid endarterectomy are generally not predictable by standard structural variables.
• Referring physicians should not rely solely on surgeon experience or hospital type.
• Actual, documented complication and death rates for surgeons and hospitals should be considered when recommending CE.
