Multicenter Study Clinical Trial
CAPTURE 2 risk-adjusted stroke outcome benchmarks for carotid artery stenting with distal embolic protection.
Many medical procedures undergo rapid evolution and process of care improvements after introduction. National outcome standards are useful to help physicians, institutions, and other stakeholders evaluate the quality of their programs and take action when suboptimal outcomes are identified. The purpose of this analysis was to derive contemporary risk-adjusted stroke rates from a large, contemporary, independently assessed outcome database within 30 days after carotid artery stenting (CAS) in the United States. ⋯ CAS outcomes in patients at high surgical risk have comparable periprocedural outcomes to published randomized trials of endarterectomy for patients at standard surgical risk. A model is presented for calculating a contemporary national standard for risk-adjusted stroke rates. Quality improvement measures could be based on relative performance to this benchmark and could improve overall outcomes for patients undergoing CAS.
