ObjectivePatient, hospital, and surgeon factors affect outcome after carotid endarterectomy (CEA). The nature and importance of hospital-specific factors, especially those unrelated to procedural volume, that affect post-CEA outcome remains poorly defined. We used a statewide database to determine the impact of several hospital-associated factors on outcome after CEA.MethodsHospital factors were established by telephone survey and validated by repeated survey as well as by the Connecticut Hospital Association, Connecticut state, and individual hospital internet Websites. All CEA in Connecticut non-federal hospitals between 1991 and 2002 were examined, including perioperative mortality, stroke, and cardiac complications. Multivariable logistic regression was used to analyze data.ResultsThere were 14,288 CEAs performed with 0.5% mortality, 1.3% stroke, and 2.4% cardiac complications. The only hospital factor independently predictive of perioperative mortality was few number of hospital beds (less than 132 beds; odds ratio (OR) 2.78, P = 0.032). Factors predictive of perioperative stroke included few number of beds (OR 1.96, P = 0.001) and absence of a critical pathway (OR 1.39, P = 0.038). Factors predictive of perioperative cardiac complications included few number of beds (OR 3.01, P = 0.003), absence of a critical pathway (OR 1.50, P = 0.001), and absence of dedicated vascular recovery beds (OR 1.35, P = 0.03). Combined mortality, stroke, or cardiac complications were independently predicted by few hospital beds (OR 4.58, P = 0.002), absence of a critical pathway (OR 1.81, P ≤ 0.0001), or inability to perform cardiac angiography (OR 3.92, P = 0.024).ConclusionsHospital-based factors, such as greater bed capacity, use of critical pathways, ability to perform cardiac angiography, or presence of a dedicated vascular recovery unit predict reduced perioperative mortality, stroke and cardiac complications from CEA. These results suggest that hospital-associated factors do impact surgical outcome and that surgeons need to optimize these factors, extrinsic to the patient and surgeon, to provide maximal quality of care.
