RESUMO
BACKGROUND: Patients undergoing arteriovenous (AV) access creation for hemodialysis often have significant comorbidities. Our goal was to quantify the long-term survival and associated risks factors for long-term mortality in these patients to aid in optimization of goals and expectations. METHODS: The Vascular Implant Surveillance and Interventional Outcomes Network Vascular Quality Initiative Medicare linked data was used to assess long-term survival in the HD registry. Demographics, comorbidities, and interventions were recorded. Because the majority of hemodialysis patients are provided Medicare, Medicare linkage was used to obtain survival data. Multivariable analysis was used to identify independent associations with mortality. RESULTS: There were 13,945 AV access patients analyzed including 10,872 (78%) AV fistulas and 3073 (22%) AV grafts. The median age was 67 years and 56% of patients were male. Approximately one-third had a prior AV access and 44.7% had prior tunneled dialysis catheters. Patients receiving an AV fistula, compared with AV grafts, were more often younger, male, White, obese, independently ambulatory, preoperatively living at home, and less often have a prior AV access and tunneled dialysis catheters (P < .05 for all). The 5-year mortality overall was 62.9% with 61.2% for AV fistulas and 68.8% for AV grafts (P < .001). On multivariable analysis for 5 year mortality, nonambulatory status (hazard ratio [HR], 1.67; 95% confidence interval [CI], 1.53-1.83; P < .001), lower extremity access (HR, 1.67; 95% CI, 1.35-2.05; P < .001), human immunodeficiency virus or acquired immunodeficiency syndrome (HR, 1.44; 95% CI, 1.13-1.82; P < .001), White race (HR, 1.43; 95% CI, 1.35-1.51; P < .001), congestive heart failure (HR, 1.33; 95% CI, 1.26-1.41; P < .001), chronic obstructive pulmonary disease (HR, 1.23; 95% CI, 1.15-1.31; P < .001), and AV graft placement (HR, 1.12; 95% CI, 1.02-1.23, P = .016) were most associated with poor survival. Factors associated with improved survival were never smoking (HR, .73; 95% CI, 0.67-0.79; P < .001), prior/quit smoking (HR, .78; 95% CI, 0.72-0.84; P < .001), preoperative home living (HR, .75; 95% CI, 0.68-0.83; P < .001), and hypertension (HR, .89; 95% CI, 0.8-0.99; P = .03). CONCLUSIONS: Long-term survival in Medicare patients undergoing AV access creation is poor with nearly two-thirds of patients having died at 5 years. There are many modifiable risk factors that may improve survival in these patients and give an opportunity for transplantation.

OBJECTIVE: The Emergency Medical Treatment and Labor Act (EMTALA) is a federal law established in 1986 to ensure that patients who present to an emergency department receive medical care regardless of means. Violations are reported to the Centers for Medicare and Medicaid Services and can result in significant financial penalties. Our objective was to assess all available EMTALA violations for vascular-related issues. METHODS: EMTALA violations in the Centers for Medicare and Medicaid Services publicly available hospital violations database from 2011 to 2018 were evaluated for vascular-related issues. Details recorded were case type, hospital type, hospital region, reasons for violation, disposition, and mortality. RESULTS: There were 7001 patients identified with any EMTALA violation and 98 (1.4%) were deemed vascular related. The majority (82.7%) of EMTALA violations occurred at urban/suburban hospitals. Based on the Association of American Medical Colleges United States region, vascular-related EMTALA violations occurred in the Northeast (7.1%), Southern (56.1%), Central (18.4%), and Western (18.4%) United States. Case types included cerebrovascular (28.6%), aortic related (22.4%; which consisted of ruptured aortic aneurysms [8.2%], aortic dissection [11.2%], and other aortic [3.1%]), vascular trauma (15.3%), venous-thromboembolic (15.3%), peripheral arterial disease (9.2%), dialysis access (5.1%), bowel ischemia (3.1%), and other (1%) cases. Patients were transferred to another facility in 41.8% of cases. The most common reasons for violation were specialty refusal or unavailability (30.6%), inappropriate documentation (29.6%), misdiagnosis (18.4%), poor communication (17.3%), inappropriate triage (13.3%), failure to obtain diagnostic laboratory tests or imaging (12.2%), and ancillary or nursing staff issues (7.1%). The overall mortality was 19.4% and 31.6% died during the index emergency department visit. Vascular conditions associated with death were venous thromboembolism (31.6%), ruptured aortic aneurysm (21.1%), aortic dissection (21.1%), other aortic causes (10.5%), vascular trauma (10.5%), and bowel ischemia (5.3%). CONCLUSIONS: Although the frequency of vascular-related EMTALA violations was low, improvements in communication, awareness of vascular disease among staff, specialty staffing, and the development of referral networks and processes are needed to ensure that patients receive adequate care and that institutions are not placed at undue risk.

BACKGROUND: Length of stay (LOS) after carotid endarterectomy (CEA) and carotid artery stenting (CAS) for asymptomatic disease is used as a quality measure and affects hospital operating margins. Patient-level Medicaid status has traditionally been associated with longer hospital LOS. Our goal was to assess the association between hospital-level Medicaid prevalence and postoperative LOS after CEA and CAS. METHODS: The National Inpatient Sample was queried from 2006-2014 for CEA and CAS performed for asymptomatic carotid stenosis. Overall hospital-level Medicaid prevalence was divided into quartiles. The quartiles were further categorized into low Medicaid prevalence (LM) (lowest quartile), medium Medicaid prevalence (MM) (second and third quartiles), and high Medicaid prevalence (HM) (fourth quartile) cohorts. The primary outcome evaluated was postoperative LOS >1 day. The secondary outcomes included perioperative/in-hospital complications and mortality. RESULTS: There were 984,283 patients with asymptomatic carotid stenosis who underwent CEA (88%) or CAS (12%). Mean postoperative LOS after CEA at hospitals with LM, MM, and HM prevalence was 1.4 ± 1.5, 2.1 ± 2.5, and 2.2 ± 2.8 days (P = 0.0001), respectively, and after CAS were 1.7 ± 2.6, 1.8 ± 2.1, and 2 ± 2.6 days (P < 0.0001), respectively. After CEA, relative to LM prevalence, MM (OR 1.62, 95% CI 1.17-2.24) and HM (OR 1.66, 95% CI 1.2-2.28) prevalence were associated with a higher likelihood of LOS > 1 day (P = 0.009). After CAS, relative to LM prevalence, HM prevalence was associated with a higher likelihood of LOS >1 day (OR 1.42, 95% CI 1.06-1.91) (P = 0.003). After CEA, neurologic (0.8% vs. 0.9% vs. 0.9%, P = 0.83) and cardiac complications (0.9% vs. 1.2% vs. 1.2%, P = 0.24) were similar among hospitals with LM, MM, and HM prevalence, respectively. After CAS, the prevalence of neurological (1.1% vs. 1% vs. 1.2%, P = 0.42) and cardiac complications (2% vs. 1.3% vs. 1.5%, P = 0.46) were also similar. After both CEA and CAS, mortality was similar among Medicaid prevalence cohorts. CONCLUSIONS: Higher hospital-level Medicaid prevalence was associated with longer LOS after CEA and CAS for asymptomatic carotid stenosis. Value-based payment models should adjust for hospital-level Medicaid prevalence to appropriately reimburse providers and hospital with higher Medicaid prevalence as well as investigate care pathways and systems improvement to help reduce LOS.

OBJECTIVE: Firearm injuries have traditionally been associated with worse outcomes compared with other types of penetrating trauma. Lower extremity trauma with vascular injury is a common presentation at many centers. Our goal was to compare firearm and non-firearm lower extremity penetrating injuries requiring vascular repair. METHODS: We analyzed the National Inpatient Sample from 2010 to 2014 for all penetrating lower extremity injuries requiring vascular repair based on International Classification of Diseases, Ninth Revision codes. Our primary outcomes were in-hospital lower extremity amputation and death. RESULTS: We identified 19,494 patients with lower extremity penetrating injuries requiring vascular repair-15,727 (80.7%) firearm injuries and 3767 (19.3%) non-firearm injuries. The majority of patients were male (91%), and intent was most often assault/legal intervention (64.3%). In all penetrating injuries requiring vascular repair, the majority (72.9%) had an arterial injury and 43.8% had a venous injury. Location of vascular injury included iliac (19.3%), femoral-popliteal (60%), and tibial (13.2%) vascular segments. Interventions included direct vascular repair (52.1%), ligation (22.1%), bypass (19.4%), and endovascular procedures (3.6%). Patients with firearm injuries were more frequently younger, black, male, and on Medicaid, with lower household income, intent of assault or legal action, and two most severe injuries in the same body region (P < .0001 for all). Firearm injuries compared with non-firearm injuries were more often reported to be arterial (75.5% vs 61.9%), to involve iliac (20.6% vs 13.7%) and femoral-popliteal vessels (64.7% vs 39.9%), to undergo endovascular repair (4% vs 2.1%), and to have a bypass (22.5% vs 6.5%; P < .05 for all). Firearm-related in-hospital major amputation (3.3% vs 0.8%; P = .001) and mortality (7.6% vs 4.2%; P = .001) were higher compared with non-firearm penetrating trauma. Multivariable analysis showed that injury by a firearm source was independently associated with postoperative major amputation (odds ratio, 4.78; 95% confidence interval, 2.07-11.01; P < .0001) and mortality (odds ratio, 1.74; 95% confidence interval, 1.14-2.65; P = .01). CONCLUSIONS: Firearm injury is associated with a higher rate of amputation and mortality compared with non-firearm injuries of the lower extremity requiring vascular repair. These data can continue to guide public health discussions about morbidity and mortality from firearm injury.

OBJECTIVE: Infectious complications of arteriovenous grafts (AVGs) are a major source of morbidity. Our aim was to characterize contemporary risk factors for upper extremity AVG infection. METHODS: The Vascular Quality Initiative (2011-2018) was queried for all patients undergoing upper extremity AVG creation. AVG infection was classified as an infection treated with antibiotics, incision and drainage, or graft removal. Multivariable analyses were used to evaluate risk factors for short- and long-term AVG infection. RESULTS: Of 1758 upper extremity AVGs, 49 (2.8%) developed significant infection within 3 months, resulting in incision and drainage in 24% and graft removal in 76% of cases. None were managed with antibiotics alone in the study sample. Patients with significant AVG infection were more likely to be white, to be insured, to have a history of coronary artery bypass graft and intravenous (IV) drug use, to be undergoing a concomitant vascular procedure, and to be discharged on an anticoagulant. In multivariable analysis, significant AVG infection within 3 months was associated with IV drug use history (odds ratio [OR], 5; 95% confidence interval [CI], 1.75-14.3; P = .003), discharge to a health care facility (OR, 2.66; 95% CI, 1.07-6.63; P = .035), discharge on an anticoagulant (OR, 2.31; 95% CI, 1.13-4.72; P = .021), white race (OR, 2.3; 95% CI, 1.21-4.34; P = .011), and female sex (OR, 2.02; 95% CI, 1.06-3.85; P = .033). Kaplan-Meier analysis showed that freedom from graft site infection at 1 year was 96.4%. Longer term graft infection at 1 year was independently associated with IV drug use history (hazard ratio [HR], 1.98; 95% CI, 1.06-3.68; P = .032), initial discharge to a health care facility (HR, 1.88; 95% CI, 1.19-2.97; P = .007), and white race (HR, 1.64; 95% CI, 1.23-2.19; P = .001). CONCLUSIONS: Although significant AVG infection was uncommon in the Vascular Quality Initiative, the majority were treated with graft removal. In select high-risk patients, extra care should be taken and alternative forms of arteriovenous access may be considered.
