[How competence are Germany's carotid surgeons. Evaluation after 15,000 interventions]

Area of Science:

• Vascular Surgery
• Health Services Research
• Medical Quality Assurance

Context:

• The German Vascular Society (DGG) initiated a mandatory data recording system for carotid reconstructive procedures to ensure surgical quality and meet legal standards.
• Data from 158 centers, encompassing 15,116 interventions, have been collected since the system's inception.
• This comprehensive dataset provides a robust foundation for evaluating surgical outcomes in carotid stenosis treatment.

Purpose:

• To assess and assure the quality of surgical interventions for carotid stenosis.
• To establish benchmarks for post-operative neurological deficits and mortality rates in carotid surgery.
• To identify factors influencing patient risk profiles and lesion characteristics in relation to surgical outcomes.

Summary:

• Analysis of 15,116 carotid reconstructive procedures reveals a severe post-operative neurological deficit rate of 1.9% and a mortality rate of 1%.
• These outcomes compare favorably with existing literature, suggesting effective quality control measures.
• Statistical analysis indicates that patient risk profiles and the specific nature and morphology of carotid lesions are significant determinants of morbidity and mortality.

Impact:

• The DGG's data recording system provides critical insights into the safety and efficacy of carotid stenosis surgery.
• Findings support the established quality standards for carotid surgery and inform risk stratification strategies.
• This initiative contributes to improved patient care and outcomes in vascular surgery through evidence-based quality monitoring.
