The incidence of PCST varies widely across registries and institutions in the So Cal VOICe. Despite the wide variation, the incidence of new postoperative MI is exceptionally low. Further studies should evaluate the cost-effectiveness of the PCST practices and future quality improvement efforts should focus on standardization of indications for PCST.
Background
The objective of this study was to examine the variation in practice patterns and associated outcomes for carotid endarterectomy (CEA) within the Southern California Vascular Outcomes Improvement Collaborative (So Cal VOICe), a regional quality group of the Vascular Quality Initiative.
Methods
All cases entered in the CEA registry by the So Cal VOICe were included in the study.
Results
From September 2010 through September 2015, 1,110 CEA cases were entered by 9 centers in the So Cal VOICe. Six hundred seventy-seven patients (61%) were male with mean age of 73 years. Nine hundred eighty-eight (89%) were hypertensive, 655 (59%) were prior or current smokers, 389 (35%) were diabetics, and 233 (21%) had coronary artery disease. Eight hundred twenty-one (74%) patients were asymptomatic (no history of ipsilateral neurologic event). The percentage of asymptomatic patients varied across the 9 centers from 57% to 91%. Preoperatively, 344 (31%) underwent cardiac stress test, center variation 13–75%, 500 (45%) underwent only duplex, center variation 11–72%. Intraoperatively, 600 (54%) underwent routine shunting, whereas 67 (6%) were shunted for an indication, and 444 (40%) were not shunted. Wound drainage was used in 422 (38%) cases, center variation 2–98%. Completion imaging by duplex and/or angiogram was performed in 766 (69%) cases, center variation 0–100%. Postoperatively, 11 (1%) patients had a new ipsilateral postoperative neurologic event, center variation 0–1.3%, 6 (0.5%) had a postoperative myocardial infarction, center variation 0–1.3%, and 8 (0.7%) required return to operating room for bleeding, center variation 0–1.3%.
Conclusions
Despite wide variation in practice patterns surrounding CEA in the So Cal VOICe, postoperative complications were uniformly low. Further work will focus on identifying practices that can be modified to improve cost-effectiveness while maintaining excellent outcomes.
Percutaneous chest tube placement is a relatively common procedure that can be performed by multiple specialties. Chest tube insertion is frequently performed by interventional radiologists (IRs) due to the advantage of imaging guidance including ultrasound (US), fluoroscopy, and computed tomography (CT) which allow for precise placement not achieved with bedside insertion techniques. Chest tube management is increasingly conducted by IRs, signifying the importance of a greater understanding of chest tube management and troubleshooting, especially for IR trainees. This manuscript is specifically tailored for the IR trainees to provide an overview of chest tube management. The practical considerations detailing the entire chest tube process are covered such as indications, technique, relevant anatomy, collection devices, commonly used catheters, postprocedural complications, lytic therapy, and troubleshooting. This guide aims to help the IR trainees feel more confident in chest tube placement and periprocedural care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
