ABSTRACT: Objective
We investigated whether mental illness is associated with lower rates of carotid endarterectomy (CEA)/carotid artery stenting (CAS) after stroke due to carotid stenosis.Methods
In this retrospective cross-sectional study, ischemic stroke cases due to carotid stenosis were identified in the 2007-2014 Nationwide (National) Inpatient Sample. Psychiatric conditions were identified by secondary ICD-9-CM diagnosis codes for schizophrenia/psychoses, bipolar disorder, depression, anxiety, or substance use disorders. Using logistic regression, we tested the association between psychiatric conditions and CEA/CAS, controlling for demographic, clinical, and hospital factors.Results
Among 37,474 included stroke cases, 6,922 (18.5%) had a psychiatric comorbidity. The presence of any psychiatric condition was associated with lower odds of CEA/CAS (adjusted odds ratio [OR] 0.84, 95% confidence interval [CI] 0.78-0.90). Schizophrenia/psychoses (OR 0.72, 95% CI 0.55-0.93), depression (OR 0.83, 95% CI 0.75-0.91), and substance use disorders (OR 0.73, 95% CI 0.65-0.83) were each associated with lower odds of CEA/CAS. The association of mental illness and CEA/CAS was dose-dependent: compared to patients without mental illness, patients with multiple psychiatric comorbidities (OR 0.74, 95% CI 0.62-0.87) had lower odds of CEA/CAS than those with only one psychiatric comorbidity (OR 0.86, 95% CI 0.79-0.92; p value for trend <0.001).Conclusion
The odds of carotid revascularization after stroke is lower in patients with mental illness, particularly those with schizophrenia/psychoses, depression, substance use disorders, and multiple psychiatric diagnoses.

Project description:ObjectiveWe sought to determine whether the use of carotid revascularization procedures after stroke due to carotid stenosis differs between minority-serving hospitals and hospitals serving predominantly white patients.MethodsWe identified ischemic stroke cases due to carotid disease, identified by ICD-9-CM codes, from 2007 to 2011 in the Nationwide Inpatient Sample. The use of carotid endarterectomy (CEA) and carotid artery stenting (CAS) was recorded. Hospitals with ≥40% racial/ethnic minority patients (minority-serving hospitals) were compared to hospitals with <40% minority patients (predominantly white hospitals [hereafter, abbreviated to white]). Logistic regression was used to evaluate the use of CEA/CAS among minority-serving and white hospitals.ResultsOf the 26,189 ischemic stroke cases meeting inclusion criteria, 20,870 (79.7%) were treated at 1,113 white hospitals and 5,319 (20.3%) received care at 325 minority-serving hospitals. Compared to patients in white hospitals, patients in minority-serving hospitals were less likely to undergo CEA/CAS (17.6%, 95% confidence interval [CI] 16.6%-18.6%, in minority-serving vs 21.2%, 95% CI 20.7%-21.8%, in white hospitals; p < 0.001). In fully adjusted logistic regression models, the odds of CEA/CAS were lower in minority-serving compared to white hospitals (odds ratio 0.81, 95% CI 0.70-0.93), independent of individual patient race/ethnicity and other measured hospital characteristics. White and Hispanic individuals had significantly lower odds of CEA/CAS in minority-serving compared to white hospitals. Patient-level racial/ethnic differences in the use of carotid revascularization procedures remained within each hospital stratum.ConclusionThe odds of carotid revascularization after stroke is lower in minority- compared to white-serving hospitals, suggesting system-level factors as a major contributor to explain race disparities in the use of carotid revascularization.

Project description:BACKGROUND AND PURPOSE:Intravenous thrombolysis (IVT) improves outcomes after acute ischemic stroke but is underused in certain patient populations. Mental illness is pervasive in the United States, and patients with comorbid psychiatric disease experience inequities in treatment for a range of conditions. We aimed to determine whether comorbid psychiatric disease is associated with differences in IVT use in acute ischemic stroke. METHODS:Acute ischemic stroke admissions between 2007 and 2011 were identified in the Nationwide Inpatient Sample. Psychiatric disease was defined by International Classification of Diseases, Ninth Revision, Clinical Modification codes for secondary diagnoses of schizophrenia or other psychoses, bipolar disorder, depression, or anxiety. Using logistic regression, we tested the association between IVT and psychiatric disease, controlling for demographic, clinical, and hospital factors. RESULTS:Of the 325?009 ischemic stroke cases meeting inclusion criteria, 12.8% had any of the specified psychiatric comorbidities. IVT was used in 3.6% of those with, and 4.4% of those without, psychiatric disease (P<0.001). Presence of any psychiatric disease was associated with lower odds of receiving IVT (adjusted odds ratio, 0.80; 95% confidence interval, 0.76-0.85). When psychiatric diagnoses were analyzed separately individuals with schizophrenia or other psychoses, anxiety, or depression each had significantly lower odds of IVT compared to individuals without psychiatric disease. CONCLUSIONS:Acute ischemic stroke patients with comorbid psychiatric disease have significantly lower odds of IVT. Understanding barriers to IVT use in such patients may help in developing interventions to increase access to evidence-based stroke care.

Project description:Background and purposeIn 2006, the American Heart Association recommended that carotid revascularization generally occurs within 2 weeks of stroke based on data from 2 trials of carotid endarterectomy (CEA). We aimed to determine whether the time between stroke and CEA or carotid artery stenting (CAS) has decreased and whether the proportion of procedures occurring within 14 days has increased.MethodsUsing validated International Classification of Diseases, Ninth Revision, Clinical Modification codes and administrative claims data from nonfederal hospitals in CA, FL, and NY, we identified patients with ischemic stroke who underwent CEA or CAS within 90 days of an ischemic stroke from 2005 to 2013. Our outcomes were the number of days between stroke and CEA/CAS and the proportion of patients undergoing CEA/CAS within the recommended 14-day period. We assessed temporal trends using nonparametric correlation, the χ2 test for trend, and logistic regression.ResultsWe identified 16 298 patients with ischemic stroke who underwent CEA/CAS within 90 days. The time from stroke to CEA/CAS decreased from 25 days (interquartile range, 5-48 days) in 2005 to 6 days (interquartile range, 3-17 days) in 2013 (P<0.001). The proportion of patients who underwent CEA/CAS within 14 days of stroke increased from 40% (95% confidence interval, 37%-43%) in 2005 to 73% (95% confidence interval, 71%-76%) in 2013 (P<0.001). These temporal trends remained significant after adjustment for patient demographics and comorbidities.ConclusionsSince 2005, revascularization for symptomatic carotid disease has been occurring progressively sooner after ischemic stroke.

Project description:Stroke occurs more commonly after carotid artery stenting than after carotid endarterectomy. Details regarding stroke type, severity, and characteristics have not been reported previously. We describe the strokes that have occurred in the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST).CREST is a randomized, open-allocation, controlled trial with blinded end-point adjudication. Stroke was a component of the primary composite outcome. Patients who received their assigned treatment within 30 days of randomization were included. Stroke was adjudicated by a panel of board-certified vascular neurologists with secondary central review of clinically obtained brain images. Stroke type, laterality, timing, and outcome were reported. A periprocedural stroke occurred among 81 of the 2502 patients randomized and among 69 of the 2272 in the present analysis. Strokes were predominantly minor (81%, n=56), ischemic (90%, n=62), in the anterior circulation (94%, n=65), and ipsilateral to the treated artery (88%, n=61). There were 7 hemorrhages, which occurred 3 to 21 days after the procedure, and 5 were fatal. Major stroke occurred in 13 (0.6%) of the 2272 patients. The estimated 4-year mortality after stroke was 21.1% compared with 11.6% for those without stroke. The adjusted risk of death at 4 years was higher after periprocedural stroke (hazard ratio, 2.78; 95% confidence interval, 1.63-4.76).Stroke, particularly severe stroke, was uncommon after carotid intervention in CREST, but stroke was associated with significant morbidity and was independently associated with a nearly 3-fold increased future mortality. The delayed timing of major and hemorrhagic stroke after revascularization suggests that these strokes may be preventable.

Project description:BackgroundCarotid artery revascularization can result in new ischemic brain lesions on diffusion-weighted magnetic resonance imaging. This study aimed to investigate the relationship between periprocedural ischemic diffusion-weighted imaging (DWI) lesions after carotid artery revascularization and recurrent long-term cerebrovascular events.MethodsA secondary observational prospective cohort analysis of existing clinical trial data was performed on 162 patients with symptomatic carotid stenosis that were previously randomized to carotid artery stenting or carotid endarterectomy in the ICSS (International Carotid Stenting Study) and included in the magnetic resonance imaging substudy. Magnetic resonance imagings were performed 1 to 7 days before and 1 to 3 days after treatment. The primary composite clinical outcome was the time to any stroke or transient ischemic attack during follow-up. Patients with new diffusion-weighted imaging (DWI) lesions on posttreatment magnetic resonance imaging scan (DWI+) were compared with patients without new lesions (DWI-).ResultsThe median time of follow-up was 8.6 years (interquartile range, 5.0-12.5). Kaplan-Meier cumulative incidence for the primary outcome after 12.5-year follow-up was 35.3% (SE, 8.9%) in DWI+ patients and 31.1% (SE, 5.6%) in DWI- patients. Uni- and multivariable regression analyses did not show significant differences (hazard ratio, 1.50 [95% CI, 0.76-2.94] and hazard ratio, 1.30 [95% CI, 0.10-1.02], respectively). Higher event rate of the primary outcome in DWI+ patients in the overall cohort was mainly caused by events in the carotid artery stenting group.ConclusionsBased on our outcome analysis within the ICSS magnetic resonance imaging substudy, DWI lesions following carotid revascularization did not seem to have a relationship with long-term stroke risk.RegistrationURL: https://www.Clinicaltrialsgov; Unique identifier: ISRCTN 25337470.

Project description:BackgroundPsychiatric comorbidity is known to contribute to illness (the state of feeling unwell/unable to rely on one's body) and increased use of healthcare resources, but the effect on inpatient outcomes in fracture care is relatively unexplored.Questions/purposesOur primary null hypothesis is that a concomitant diagnosis of depression, anxiety, dementia, or schizophrenia is not associated with (1) discharge to another care facility rather than home after lower extremity fractures. Secondary study questions address the associations between psychiatric comorbidity and (2) longer inpatient stay and inpatient (3) adverse events; (4) blood transfusion; and (5) mortality after lower extremity fractures.MethodsUsing the National Hospital Discharge Survey database, we analyzed a total estimated number of 10,669,449 patients with lower limb fractures from 1990 to 2007. Sixty-four percent were women, and the mean±SD age was 67±22 years. The prevalence in the study population was 3.2% for depression, 1.6% for anxiety, 0.6% for schizophrenia, and 2.9% for dementia.ResultsA discharge diagnosis of psychiatric comorbidity was associated with a lower rate of discharge to home after accounting for an association with greater medical comorbidity (schizophrenia: odds ratio [OR], 5.6, 95% confidence interval [CI], 5.5-5.8; dementia: OR, 1.3, 95% CI, 1.2-1.3; depression: OR, 1.2, 95% CI, 1.2-1.3; anxiety: OR, 1.04, 95% CI, 1.02-1.06). Hospital stay was longer for patients with schizophrenia and dementia but shorter in patients with depression or anxiety compared with patients without any mental disorders. Schizophrenia was associated with more in-hospital adverse events and depression and anxiety with fewer events. A diagnosis of depression was associated with blood transfusion. Psychiatric comorbidity was not associated with a higher risk of in-hospital death.ConclusionsOptimal inpatient management of patients with lower extremity fractures should account for the influence of psychiatric comorbidities, dementia and schizophrenia in particular.

Project description:ImportanceCarotid artery stenting has been limited to use in patients with high surgical risk; outcomes in patients with standard surgical risk are not well known.ObjectiveTo compare stroke, death, and myocardial infarction outcomes following transcarotid artery revascularization vs carotid endarterectomy in patients with standard surgical risk.Design, setting, and participantsThis retrospective propensity-matched cohort study was conducted from August 2016 to August 2019 with follow-up until August 31, 2020, using data from the multicenter Vascular Quality Initiative Carotid Artery Stent and Carotid Endarterectomy registries. Patients with standard surgical risk, defined as those lacking Medicare-defined high medical or surgical risk characteristics and undergoing transcarotid artery revascularization (n = 2962) or carotid endarterectomy (n = 35 063) for atherosclerotic carotid disease. In total, 760 patients were excluded for treatment of multiple lesions or in conjunction with other procedures.ExposuresTranscarotid artery revascularization vs carotid endarterectomy.Main outcomes and measuresThe primary outcome was a composite end point of 30-day stroke, death, or myocardial infarction or 1-year ipsilateral stroke.ResultsAfter 1:3 matching, 2962 patients undergoing transcarotid artery revascularization (mean [SD] age, 70.4 [6.9] years; 1910 [64.5%] male) and 8886 undergoing endarterectomy (mean [SD] age, 70.0 [6.5] years; 5777 [65.0%] male) were identified. There was no statistically significant difference in the risk of the primary composite end point between the 2 cohorts (transcarotid 3.0% vs endarterectomy 2.6%; absolute difference, 0.40% [95% CI, -0.43% to 1.24%]; relative risk [RR], 1.14 [95% CI, 0.87 to 1.50]; P = .34). Transcarotid artery revascularization was associated with a higher risk of 1-year ipsilateral stroke (1.6% vs 1.1%; absolute difference, 0.52% [95% CI, 0.03 to 1.08]; RR, 1.49 [95% CI, 1.05 to 2.11%]; P = .02) but no difference in 1-year all-cause mortality (2.6% vs 2.5%; absolute difference, -0.13% [95% CI, -0.18% to 0.33%]; RR, 1.04 [95% CI, 0.78 to 1.39]; P = .67).Conclusions and relevanceIn this study, the risk of 30-day stroke, death, or myocardial infarction or 1-year ipsilateral stroke was similar in patients undergoing transcarotid artery revascularization compared with those undergoing endarterectomy for carotid stenosis.

Project description:Importance:The Carotid Revascularization Endarterectomy vs Stenting Trial (CREST) showed greater safety of carotid artery stenting (CAS) in patients younger than 70 years and carotid endarterectomy (CEA) in those older than 70 years. It is unknown how the result of CREST has influenced carotid revascularization choices in the United States. Objective:To evaluate national patterns in CAS performance in patients older than 70 years in the post-CREST (2011-2014) compared with the pre-CREST (2007-2010) era. Design, Setting, and Participants:All adults older than 70 years undergoing carotid revascularization in the United States from 2007 to 2014 were retrospectively identified from the 2007-2014 National Inpatient Sample using International Classification of Disease, Ninth Revision procedural codes. From 61 324 882 unweighted hospitalizations contained in the 2007-2014 National Inpatient Sample, 494 733 weighted carotid revascularization admissions in adults older than 70 years were identified using International Classification of Disease, Ninth Revision procedural codes. Main Outcomes and Measures:The proportion of CAS performed in all age groups over time was estimated and multivariable-adjusted models were used to compare the odds of receiving CAS in the pre-CREST with those in the post-CREST era in adults older than 70 years. Results:A total of 41.8% of all patients were women, and mean (SE) age at presentation was 78.1 (0.03) years. A total of 16.3% of CAS and 10.1% of CEA procedures were performed in patients with symptomatic stenosis. The proportion of patients older than 70 years receiving CAS increased from 11.9% in the pre-CREST to 13.8% in the post-CREST era (P = .005). In multivariable models, the odds of receiving CAS increased by 13% in all patients older than 70 years in the post-CREST compared with the pre-CREST period (odds ratio [OR], 1.13, 95% CI, 1.00-1.28, P = .04), including symptomatic women (OR, 1.31, 1.05-1.65, P = .02). Symptomatic stenosis (OR 1.39; 95% CI, 1.27-1.52; P < .001), congestive heart failure (OR, 1.48; 95% CI, 1.35-1.63; P < .001), and peripheral vascular disease (OR, 1.35; 95% CI, 1.27-1.43; P < .001) were associated with higher odds of CAS; comorbid hypertension (OR, 0.70; 95% CI, 0.66-0.74; P < .001), smoking (OR, 0.84; 95% CI, 0.78-0.91; P < .001), and weekend admission (OR, 0.77; 95% CI, 0.68-0.88; P < .001) were negatively associated with the odds of CAS. Conclusions and Relevance:Despite concerns for higher periprocedural complications with CAS in elderly patients, the odds of CAS increased in the post-CREST compared with pre-CREST era in patients older than 70 years, including symptomatic women.

Project description:Several carotid endarterectomy randomized, controlled trials and series have reported higher perioperative stroke and death rates for women compared with men. The potential for this same relationship with carotid artery stenting was examined in the lead-in phase of the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST).CREST compares efficacy of carotid endarterectomy and carotid artery stenting in preventing stroke, myocardial infarction, and death in the periprocedural period and ipsilateral stroke over the follow-up period. CREST included a "lead-in" phase of symptomatic (>or=50% stenosis) and asymptomatic (>or=70% stenosis) patients. Patients were examined by a neurologist preprocedure, at 24 hours, and at 30 days. Review of stroke and death was by an independent events committee. The association of sex with periprocedural stroke and death was examined in 1564 patients undergoing carotid artery stenting (26.5% symptomatic).Women comprised 37% of the lead-in cohort and did not differ from men by age, symptomatic status, or characteristics of the internal carotid artery. The 30-day stroke and death rate for women was 4.5% (26 of 579; 95% CI, 3.0% to 6.5%) compared with 4.2% (41 of 985; 95% CI, 3.0% to 5.6%) for men. The difference in stroke and death rate was not significant nor were there any significant differences by sex after adjustment for age, arterial characteristics, or cardiovascular risk factors.These results do not provide evidence that women have a higher carotid artery stenting stroke and death rate compared with men. The potential differential periprocedural risk by sex will be prospectively addressed in the randomized phase of CREST.

Project description:Two positive randomized trials established carotid endarterectomy (CEA) as a superior treatment to medical management alone for the treatment of asymptomatic carotid artery stenosis. However, advances in medical therapy have led to an active and spirited debate about the best treatment for asymptomatic carotid stenosis. The Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis (CREST 2) trial aims to better define the best treatment for the average patient with severe asymptomatic carotid stenosis. Enrollment in the trial may be hampered by strong opinions on either side of the debate. It is important to realize that equipoise exists and that neither the old data on CEA nor the new data on optimal medical therapy provide a rigorous answer. The assumption that medical therapy has already been proven superior to revascularization procedures may hinder both enrollment in the trial and technical advancements in revascularization procedures.
