New Angiology Study Results Reported from Boston University [The Association of Publication of Center for Medicaid and Medicare Services Guidelines for Carotid Artery Angioplasty and Stenting (CAS) and CREST Results on the Utilization of CAS in ...]

By a News Reporter-Staff News Editor at Insurance Weekly News -- Research findings on Angiology are discussed in a new report. According to news reporting out of Boston, Massachusetts, by VerticalNews editors, research stated, "Since the 2004 approval of carotid artery angioplasty and stenting (CAS), there have been 2 seminal publications about CAS reimbursement (Center for Medicaid and Medicare Several guidelines [CMSG]; 2008) and clinical outcomes (Carotid Revascularization Endarterectomy versus Stent Trial [CREST]; 2010). We explored trends in CAS utilization after these publications nationally."

Our news journalists obtained a quote from the research from Boston University, "The most recent datasets of the nationwide inpatient sample (NIS) was queried for patients undergoing carotid revascularization. Utilization proportions of CAS were calculated quarterly from 2005 to 2011 for NIS. Three-time intervals related to CMSG and CREST publication were selected 2005-2008, 2008-2010, and after 2010. Logistic regression with piecewise linear trend for time was used to estimate different trends in CAS utilization for overall samples and for neurologically asymptomatic and symptomatic cases. The majority (95%) of the carotid revascularizations were performed on asymptomatic patients. Overall, CAS utilization constituted 12.5% of carotid revascularization procedures with a significant period increase of CAS; from 9.4% to 14%; P< 0.001. There was a small but significant decrease in the rate of CAS utilization after CMSG were published corresponding to a 2% decline in the odds ratio (OR) of CAS per quarter (OR, 0.98; 95% confidence interval, 0.97-0.99; P = 0.001). After CREST, CAS utilization continued to increase in both NIS but the rate of increase did not change significantly from the prepublication to the postpublication time interval. The odds of in-hospital mortality and postoperative stroke were independently and significantly higher for CAS patients in both overall and within the symptomatic cohorts. In all 3 periods of the study, and compared to carotid endarterectomy, the odds of mortality and postoperative stroke were significantly higher among patients who underwent CAS. Although overall utilization of CAS increased since 2005, it was not uniformly associated by the publication of CMSG or CREST."

According to the news editors, the research concluded: "Despite increased utilization, the odds of adverse outcomes were independently higher among CAS patients."
