RESUMO
BACKGROUND: Efforts to improve prescription of oral anticoagulation (OAC) drugs in patients with atrial fibrillation have had limited success in improving guideline adherence. METHODS: We evaluated adherence to the American College of Cardiology/American Heart Association performance measures for OAC in eligible patients with a CHA2DS2-VASc score ≥2 and trends in prescription over time in the American Heart Association's Get With The Guidelines-AFIB (atrial fibrillation) registry. Adjusted associations with in-hospital outcomes were also determined. The cohort included 33 235 patients with a CHA2DS2-VASc score ≥2 who were admitted for atrial fibrillation and were enrolled at 115 sites between January 1, 2013, and September 31, 2017. RESULTS: The median (25th, 75th percentile) age was 73 years (65, 81 years); 51% were female; and the median (25th, 75th percentile) CHA2DS2-VASc score was 4 (3, 5). At admission, 16 206 (59.5%) of 27 221 patients with a previous diagnosis of atrial fibrillation were taking OAC agents, and OAC drug use at admission was associated with a lower adjusted odds of in-hospital ischemic stroke (odds ratio, 0.38; 95% CI, 0.24-0.59; P<0.0001). At discharge, prescription of OAC in eligible patients (no contraindications) was 93.5% (n=25 499 of 27 270). In a sensitivity analysis, when excluding only strict contraindications (4.6%, n=1497 of 32 806), OAC prescription at discharge was 80.3%. OAC prescription at discharge was higher in those aged ≤75 years, men, those with heart failure, those with previous atrial fibrillation ablation, and those with rhythm control ( P<0.0001 for all). OAC use was lowest in Hispanic patients (90.2%, P<0.0001). Prescription of OAC at discharge in eligible patients improved over time from 79.9% to 96.6% ( P<0.0001). CONCLUSIONS: Among hospitals participating in the GWTG-AFIB quality improvement program, OAC prescription at discharge in eligible guideline-indicated patients increased significantly and improved consistently over time. These data confirm that high-level adherence to guideline-recommended stroke prevention is achievable.

BACKGROUND: Endovascular therapy (EVT) is standard of care in patients with acute disabling ischemic stroke attributable to large-vessel occlusion and is more effective when delivered quickly. It is currently unclear whether time targets achieved in clinical trials can be achieved in clinical practice. We describe interval times from patient arrival in the emergency department (door) to first pass (treatment initiation) in patients receiving EVT within Get With The Guidelines-Stroke hospitals and analyze patient- and hospital-level variables associated with these times. METHODS: Data are from sites participating fully as Comprehensive Stroke Centers within Get With The Guidelines-Stroke hospitals from October 2014 to September 2016. Workflow times analyzed include door to imaging, imaging to arterial access, arterial access to first pass, and the composite door to first pass time. Data are described overall and by calendar-year quarters. Multivariable modeling was used to identify patient- and hospital-level variables associated with workflow times. RESULTS: Among 2929 patients with EVT from 195 hospitals (median age, 71 years [interquartile range {IQR}, 60-81]; 50.7% female; median baseline National Institute of Health Stroke Score, 17 [IQR, 12-22]; median annual EVT administration number, 16 [IQR, 10-27]), median door to first pass time was 130 minutes (IQR, 101-170 minutes), door to imaging time was 12 minutes (IQR, 7-20 minutes), imaging to arterial puncture time was 93 minutes (IQR, 68-126 minutes), and arterial puncture to first pass time was 18 minutes (IQR, 4-31 minutes). Overall, 3% patients achieved a door to first pass time ≤60 minutes. A statistically significant linear time trend was noted for door to first pass time (quarter 4 year 2014 median time, 134.5 minutes to quarter 3 year 2016 median time, 128 minutes, P=0.002). In multivariable analysis, older age, arrival during nonregular hours, and history of diabetes mellitus were associated with longer door to first pass time. Hospitals achieving shorter door to intravenous alteplase administration (door to needle) times were more likely to achieve faster door to first pass time ( P<0.001). Each 5 cases/y increase in EVT case volume was associated with a 3% shorter door to first pass time, up to a case volume of 40 per year ( P<0.001). CONCLUSIONS: Although EVT treatment times are modestly improving, additional efforts are needed to streamline workflow so that the true potential of this treatment is realized. These data may inform benchmark goals for EVT workflow times.

BACKGROUND: Little is known about how hospitals are connected in the transfer of ischemic stroke (IS) patients. We aimed to describe differences in characteristics of transferred versus nontransferred patients and between transferring and receiving hospitals in the Northeastern United States, and to describe changes over time. METHODS: We used Medicare claims data, and a subset linked with the Get with the Guidelines-Stroke registry from 2007 to 2011. Receiving hospitals were those with annual IS volume greater than or equal to 120 and greater than or equal to 15% received as transfers, and transferring hospitals were nonaccepting hospitals that transferred greater than or equal to 15% of their total (ED plus inpatient) IS patient discharges. A transferring-to-receiving hospital connection was identified if greater than or equal to 5 patients per year were shared. ArcGIS 10.3.1 was used for network visualization. RESULTS: Among 177,270 admissions to 402 Northeast hospitals, 6906 (3.9%) patients were transferred. Transferred patients were younger with more severe strokes (78 versus 81 years, P < .001; National Institutes of Health Stroke Severity 7 versus 5, P < .001), and were as likely to receive tissue plasminogen activator as nontransferred (P = .29). From 2007 to 2011, there were more patients transferred (960 [3%] to 1777 [6%], P < .001), and more transferring hospitals (46 [12%] to 91 [24%], P < .001), and receiving hospitals (6 [2%] to 16 [4%], P < .001). Most transferring hospitals were exclusively connected to a single receiving hospital. CONCLUSIONS: From 2007 to 2011, hospitals in the United States Northeast became more connected in the care of IS patients, with increasing patient transfers and hospital connections. Yet most hospitals remained unconnected. Further characterization of this transfer network will be important for understanding and improving regional stroke systems of care.

BACKGROUND: Beginning in December 2014, a series of pivotal trials showed that endovascular thrombectomy (EVT) was highly effective, prompting calls to reorganize stroke systems of care. However, there are few data on how these trials influenced the frequency of EVT in clinical practice. We used data from the Get With The Guidelines-Stroke program to determine how the frequency of EVT changed in US practice. METHODS: We analyzed prospectively collected data from a cohort of 2 437 975 patients with ischemic stroke admitted to 2222 participating hospitals between April 2003 and the third quarter of 2016. Weighted linear regression with 2 linear splines and a knot at January 2015 was used to compare the slope of the change in EVT use before and after the pivotal trials were published. Potentially eligible patients were defined as last known well to arrival time ≤4.5 hours and National Institutes of Health Stroke Scale score ≥6. RESULTS: The frequency of EVT use was slowly increasing before January 2015 but then sharply accelerated thereafter. In the third quarter 2016, EVT was provided to 3.3% of all patients with ischemic stroke at all hospitals, representing 15.1% of all patients who were potentially eligible for EVT based on stroke duration and severity. At EVT-capable hospitals, 7.5% of all patients with ischemic stroke were treated in the third quarter of 2016, including 27.3% of the potentially eligible patients. From 2013 to 2016, case volumes nearly doubled at EVT-capable hospitals. Mean case volume per EVT-capable hospital was 37.6 per year in the last 4 quarters. EVT case volumes increased in nearly all US states from 2014 to the last 4 quarters, but with persistent geographic variation unexplained by differences in potential patient eligibility. CONCLUSIONS: EVT use is increasing rapidly; however, there are still opportunities to treat more patients. Reorganizing stroke systems to route patients to adequately resourced EVT-capable hospitals might increase treatment of eligible patients, improve outcomes, and reduce disparities.

BACKGROUND AND PURPOSE: The recommended treatment for ischemic stroke is tPA (tissue-type plasminogen activator). Although sickle cell disease (SCD) represents no known contraindication to tPA, National Heart Lung and Blood Institute of the National Institutes of Health recommended acute exchange transfusion for stroke in SCD, not tPA. Data on safety and outcomes of tPA in patients are needed to guide tPA use in SCD. METHODS: We matched patients from the American Heart Association and American Stroke Association Get With The Guidelines-Stroke registry with SCD to patients without SCD and compared usage, complications, and discharge outcomes after tPA. Multivariable logistic regression models using generalized estimating equations were used to assess outcomes. RESULTS: From 2 016 652 stroke patients admitted to Get With The Guidelines-Stroke sites in the United States, 832 SCD and 3328 non-SCD controls with no differences in admission National Institutes of Health Stroke Scale or blood pressure were identified. Neither the fraction receiving thrombolytic therapy (8.2% for SCD versus 9.4% non-SCD) nor symptomatic intracranial hemorrhage (4.9% of SCD versus 3.2% non-SCD; P=0.4502) was different. There was no difference in a prespecified set of outcome measures for those with SCD compared with controls. CONCLUSIONS: Coexistent SCD had no significant impact on the safety or outcome of thrombolytic therapy in acute ischemic stroke. Although the sample size is relatively small, these data suggest that adults with SCD and acute ischemic stroke should be treated with thrombolysis, if they otherwise qualify. Addition studies, however, should track the intracranial hemorrhage rate and provide information on other SCD-related care such as transfusion.

BACKGROUND AND PURPOSE: Primary stroke center (PSC) certification was established to identify hospitals providing evidence-based care for stroke patients. The numbers of PSCs certified by Joint Commission (JC), Healthcare Facilities Accreditation Program, Det Norske Veritas, and State-based agencies have significantly increased in the past decade. This study aimed to evaluate whether PSCs certified by different organizations have similar quality of care and in-hospital outcomes. METHODS: The study population consisted of acute ischemic stroke patients who were admitted to PSCs participating in Get With The Guidelines-Stroke between January 1, 2010, and December 31, 2012. Measures of care quality and outcomes were compared among the 4 different PSC certifications. RESULTS: A total of 477 297 acute ischemic stroke admissions were identified from 977 certified PSCs (73.8% JC, 3.7% Det Norske Veritas, 1.2% Healthcare Facilities Accreditation Program, and 21.3% State-based). Composite care quality was generally similar among the 4 groups of hospitals, although State-based PSCs underperformed JC PSCs in a few key measures, including intravenous tissue-type plasminogen activator use. The rates of tissue-type plasminogen activator use were higher in JC and Det Norske Veritas (9.0% and 9.8%) and lower in State and Healthcare Facilities Accreditation Program certified hospitals (7.1% and 5.9%) (P<0.0001). Door-to-needle times were significantly longer in Healthcare Facilities Accreditation Program hospitals. State PSCs had higher in-hospital risk-adjusted mortality (odds ratio 1.23, 95% confidence intervals 1.07-1.41) compared with JC PSCs. CONCLUSIONS: Among Get With The Guidelines-Stroke hospitals with PSC certification, acute ischemic stroke quality of care and outcomes may differ according to which organization provided certification. These findings may have important implications for further improving systems of care.

BACKGROUND AND PURPOSE: Although the use of antiplatelet therapy (APT) is associated with the risk of intracerebral hemorrhage (ICH), there are limited data on prestroke APT and outcomes, particularly among patients on combination APT (CAPT). We hypothesized that the previous use of antiplatelet agents is associated with increased mortality in ICH. METHODS: We analyzed data of 82 576 patients with ICH who were not on oral anticoagulant therapy from 1574 Get with the Guidelines-Stroke hospitals between October 2012 and March 2016. Patients were categorized as not on APT, on single-APT (SAPT), and CAPT before hospital presentation with ICH. We described baseline characteristics, comorbidities, hospital characteristics and outcomes, overall and stratified by APT use. RESULTS: Before the diagnosis of ICH, 65.8% patients were not on APT, 29.5% patients were on SAPT, and 4.8% patients were on CAPT. There was an overall modest increased in-hospital mortality in the APT group versus no APT group (24% versus 23%; adjusted odds ratio, 1.05; 95% confidence interval, 1.01-1.10). Although patients on SAPT and CAPT were older and had higher risk profiles in terms of comorbidities, there was no significant difference in the in-hospital mortality among patients on SAPT versus those not on any APT (23% versus 23%; adjusted odds ratio, 1.01; 95% confidence interval, 0.97-1.05). However, in-hospital mortality was higher among those on CAPT versus those not on APT (30% versus 23%; adjusted odds ratio, 1.50; 95% confidence interval, 1.39-1.63). CONCLUSIONS: Our study suggests that among patients with ICH, previous use of CAPT, but not SAPT, was associated with higher risk for in-hospital mortality.

BACKGROUND AND PURPOSE: Intravenous tissue-type plasminogen activator (tPA) is a proven treatment for acute ischemic stroke, but there has been limited evaluation among patients aged ≥90 years. METHODS: We analyzed data from the Get With The Guidelines-Stroke national quality improvement registry from January 2009 to April 2013. Frequency, determinants, and outcomes of tPA use were compared among patients aged ≥90 and 3 younger age groups (18-64, 65-79, and 80-89 years). RESULTS: Among 35 708 patients from 1178 sites who arrived within 2 hours of time last known well and received tPA, 2585 (7.2%) were ≥90 years. Compared with younger patients, the rate of tPA use among patients without a documented contraindication was lower among patients aged ≥90 years (67.4% versus 84.1% in 18-89-year olds; P<0.0001). Discharge outcomes among individuals aged ≥90 years included discharge to home or acute rehabilitation in 31.4%, independent ambulation at discharge in 13.4%, symptomatic hemorrhage in 6.1%, and in-hospital mortality or hospice discharge in 36.4%. On multivariable analysis, good functional outcomes generally occurred less often and mortality more often among patients aged ≥90 years. The risk of symptomatic hemorrhage was increased compared with patients <65 years but was not significantly different than the risk in 66- to 89-year olds. CONCLUSIONS: The use of intravenous tPA among those aged ≥90 years is lower than in younger patients. When fibrinolytic therapy is used, the risk of symptomatic hemorrhage is not higher than in 66- to 89-year olds; however, mortality is higher and functional outcomes are lower.

BACKGROUND: Stroke, which is a rare but devastating event during pregnancy, occurs in 34 of every 100,000 deliveries; obstetricians are often the first providers to be contacted by symptomatic patients. At least one-half of pregnancy-related strokes are likely to be of the ischemic stroke subtype. Most pregnant or newly postpartum women with ischemic stroke do not receive acute stroke reperfusion therapy, although this is the recommended treatment for adults. Little is known about these therapies in pregnant or postpartum women because pregnancy has been an exclusion criterion for all reperfusion trials. Until recently, pregnancy and obstetric delivery were specifically identified as warnings to intravenous alteplase tissue plasminogen activator in Federal Drug Administration labeling. OBJECTIVE: The primary study objective was to compare the characteristics and outcomes of pregnant or postpartum vs nonpregnant women with ischemic stroke who received acute reperfusion therapy. STUDY DESIGN: Pregnant or postpartum (<6 weeks; n = 338) and nonpregnant (n = 24,303) women 18-44 years old with ischemic stroke from 1991 hospitals that participated in the American Heart Association's Get With the Guidelines-Stroke Registry from 2008-2013 were identified by medical history or International Classification of Diseases, Ninth Revision, codes. Acute stroke reperfusion therapy was defined as intravenous tissue plasminogen activator, catheter-based thrombolysis, or thrombectomy or any combination thereof. A sensitivity analysis was done on patients who received intravenous tissue plasminogen activator monotherapy only. Chi-square tests were used for categoric variables, and Wilcoxon Rank-Sum was used for continuous variables. Conditional logistic regression was used to assess the association of pregnancy with short-term outcomes. RESULTS: Baseline characteristics of the pregnant or postpartum vs nonpregnant women with ischemic stroke revealed a younger group who, despite greater stroke severity, were less likely to have a history of hypertension or to arrive via emergency medical services. There were similar rates of acute stroke reperfusion therapy in the pregnant or postpartum vs nonpregnant women (11.8% vs 10.5%; P = .42). Pregnant or postpartum women were less likely to receive intravenous tissue plasminogen activator monotherapy (4.4% vs 7.9%; P = .03), primarily because of pregnancy and recent surgery. There was a trend toward increased symptomatic intracranial hemorrhage in the pregnant or postpartum patients who were treated with tissue plasminogen activator, yet no cases of major systemic bleeding or in-hospital death occurred, and there were similar rates of discharge to home. Data on the timing of pregnancy, which were available in 145 of 338 cases, showed that 44.8% of pregnancy-related strokes were antepartum, that 2.8% occurred during delivery, and that 52.4% were during the postpartum period. CONCLUSIONS: Using data from the Get With the Guidelines-Stroke Registry to assemble the largest cohort of pregnant or postpartum ischemic stroke patients who had been treated with reperfusion therapy, we observed that pregnant or postpartum women had similarly favorable short-term outcomes and equal rates of total reperfusion therapy to nonpregnant women, despite lower rates of intravenous tissue plasminogen activator use. Future studies should identify the characteristics of pregnant and postpartum ischemic stroke patients who are most likely to safely benefit from reperfusion therapy.

BACKGROUND AND PURPOSE: Race/ethnic-related differences in safety of intravenous thrombolytic therapy have been shown in patients with myocardial infarction, but not studied in ischemic stroke. METHODS: Using data from the Get With The Guidelines (GWTG)-Stroke program (n=54 334), we evaluated differences in risk-adjusted bleeding rates (any, symptomatic intracerebral hemorrhage [sICH], serious life-threatening [excluding sICH], or other) and mortality in white (n=40 411), black (n=8243), Hispanic (n=4257), and Asian (n=1523) patients receiving intravenous tissue-type plasminogen activator (tPA) for acute ischemic stroke. RESULTS: Compared with white patients, overall adjusted hemorrhagic complications after tPA were higher in black (odds ratio, 1.14, 95% confidence interval, 1.04-1.28) and Asian (odds ratio, 1.36, 95% confidence interval, 1.14-1.61) patients. Overall adjusted bleeding complications in Hispanics were similar to those of whites. Increased risk of overall bleeding in Asians was related to higher risk of adjusted sICH (odds ratio, 1.47, 95% confidence interval, 1.19-1.82), whereas in blacks, it was related to higher risk of other bleeding. No significant race-related difference was noted in risk of serious or life-threatening bleeding or in overall mortality or death in patients with sICH or any hemorrhagic complications. CONCLUSIONS: In patients with stroke receiving tPA, hemorrhagic complications were slightly higher in blacks and Asians, but not in Hispanics compared with whites. Asians also faced significantly higher risk for sICH relative to other race/ethnic groups. Future studies are needed to evaluate whether reduction in tPA dose similar to that used in many Asian countries could improve the safety of tPA therapy in Asians in the United States with acute ischemic strokes while maintaining efficacy.

BACKGROUND AND PURPOSE: Analysis of quality of care for in-hospital stroke has not been previously performed at the national level. This study compares patient characteristics, process measures of quality, and outcomes for in-hospital strokes with those for community-onset strokes in a national cohort. METHODS: We performed a retrospective cohort study of the Get With The Guidelines-Stroke (GWTG-Stroke) database of The American Heart Association from January 2006 to April 2012, using data from 1280 sites that reported ≥1 in-hospital stroke. Patient characteristics, comorbid illnesses, medications, quality of care measures, and outcomes were analyzed for 21 349 in-hospital ischemic strokes compared with 928 885 community-onset ischemic strokes. RESULTS: Patients with in-hospital stroke had more thromboembolic risk factors, including atrial fibrillation, prosthetic heart valves, carotid stenosis, and heart failure (P<0.0001), and experienced more severe strokes (median National Institutes of Health Stroke Score 9.0 versus 4.0; P<0.0001). Using GWTG-Stroke achievement measures, the proportion of patients with defect-free care was lower for in-hospital strokes (60.8% versus 82.0%; P<0.0001). After accounting for patient and hospital characteristics, patients with in-hospital strokes were less likely to be discharged home (adjusted odds ratio 0.37; 95% confidence intervals [0.35-0.39]) or be able to ambulate independently at discharge (adjusted odds ratio 0.42; 95% confidence intervals [0.39-0.45]). In-hospital mortality was higher for in-hospital stroke (adjusted odds ratio 2.72; 95% confidence intervals [2.57-2.88]). CONCLUSIONS: Compared with community-onset ischemic stroke, patients with in-hospital stroke experienced more severe strokes, received lower adherence to process-based quality measures, and had worse outcomes. These findings suggest there is an important opportunity for targeted quality improvement efforts for patients with in-hospital stroke.

BACKGROUND AND PURPOSE: Although racial/ethnic differences in care are pervasive in many areas of medicine, little is known whether intracerebral hemorrhage (ICH) care processes or outcomes differ by race/ethnicity. METHODS: We analyzed 123 623 patients with ICH (83 216 white, 22 147 black, 10 519 Hispanic, and 7741 Asian) hospitalized at 1199 Get With The Guidelines-Stroke hospitals between 2003 and 2012. Multivariable logistic regression with generalized estimating equation was used to evaluate the association among race, stroke performance measures, and in-hospital outcomes. RESULTS: Relative to white patients, black, Hispanic, and Asian patients were significantly younger, but more frequently had more severe stroke (median National Institutes of Health Stroke Scale, 9, 10, 10, and 11, respectively; P<0.001). After adjustment for both patient and hospital-level characteristics, black patients were more likely to receive deep venous thrombosis prophylaxis, rehabilitation assessment, dysphagia screening, and stroke education, but less likely to have door to computed tomographic time ≤25 minutes and smoking cessation counseling than whites. Both Hispanic and Asian patients had higher odds of dysphagia screening but lower odds of smoking cessation counseling. In-hospital all-cause mortality was lower for blacks (23.0%), Hispanics (22.8%), and Asians (25.3%) than for white patients (27.6%). After risk adjustment, all minority groups had lower odds of death, of receiving comfort measures only or of being discharged to hospice. In contrast, they were more likely to exceed the median length of stay when compared with white patients. CONCLUSIONS: Although individual quality indicators in ICH varied by race/ethnicity, black, Hispanic, and Asian patients with ICH had lower risk-adjusted in-hospital mortality than white patients with ICH.

BACKGROUND: Studies on outcomes among patients with heart failure (HF) with preserved left ventricular ejection fraction (HFpEF), borderline left ventricular ejection fraction (HFbEF), and reduced left ventricular ejection fraction (HFrEF) remain limited. We sought to characterize mortality and readmission in patients with HF in the contemporary era. METHODS: Get With The Guidelines-HF was linked to Medicare data for longitudinal follow-up. Patients were grouped into HFpEF (left ventricular ejection fraction [EF] ≥ 50%), HFbEF (40% ≤ EF < 50%), and HFrEF (EF < 40%). Multivariable models were constructed to examine the relationship between EF and outcomes at 30 days and 1 year and to study trends over time. RESULTS: A total of 40,239 patients from 220 hospitals between 2005 and 2011 were included in the study: 18,897 (47%) had HFpEF, 5,626 (14%) had HFbEF, and 15,716 (39%) had HFrEF. In crude survival analysis, patients with HFrEF had slightly increased mortality compared with HFbEF and HFpEF. After risk adjustment, mortality at 1 year was not significantly different for HFrEF, HFbEF, and HFpEF (HFrEF vs HFpEF, hazard ratio [HR] 1.040 [95% CI 0.998-1.084], and HFbEF vs HFpEF, HR 0.967 [95% CI 0.917-1.020]). Patients with HFpEF had increased risk of all-cause readmission compared with HFrEF. Conversely, risk of cardiovascular and HF readmissions were higher in HFrEF and HFbEF compared with HFpEF. CONCLUSIONS: Among patients hospitalized with HF, patients with HFpEF and HFbEF had slightly lower mortality and higher all-cause readmission risk than patients with HFrEF, although the mortality differences did not persist after risk adjustment. Irrespective of EF, these patients experience substantial mortality and readmission highlighting the need for new therapeutic strategies.

BACKGROUND: Longitudinal data directly comparing the rates of death and rehospitalization of patients discharged after transient ischemic attack (TIA) versus acute ischemic stroke (AIS) are lacking. METHODS: Data were analyzed from 2802 patients (TIA n = 552; AIS n = 2250) admitted to 100 U.S. hospitals participating in the Get With The Guidelines-Stroke and the Adherence Evaluation of Acute Ischemic Stroke-Longitudinal registry. The primary composite outcome was the adjusted rate of all-cause death and rehospitalization over 1 year after discharge. Four additional single or combined outcomes were explored. RESULTS: Compared with AIS, TIA patients were older (median 69 v 66 years; P = .007) and more likely female (53.3% v 44.2%; P < .0001). Secondary prevention medication use after hospital discharge was less intensive after TIA, with underuse for both conditions. All-cause death or rehospitalization at 1 year was similar for TIA and AIS patients (37.7% v 34.6%; P = .271); the frequency for TIA patients was higher after covariate adjustment (hazard ratio [HR] 1.19; 95% confidence interval [CI] 1.01-1.41). One-year all-cause mortality was similar among those with TIA compared to AIS patients (3.8% v 5.7%; P = .071; adjusted HR 0.86; 95% CI 0.52-1.42). All-cause rehospitalizations were higher for TIA compared to AIS patients (36.4% v 33.0%; P = .186; adjusted HR 1.20; 95% CI 1.02-1.42), but similar for stroke rehospitalizations (10.1% v 7.4%; P = .037; adjusted HR 1.38, 95% CI 0.997-1.92). CONCLUSIONS: Patients with TIA have similar or worse 12-month postdischarge risk of death or rehospitalization as compared with those with AIS. Outcomes after TIA and AIS might be improved with better adherence to secondary preventive guidelines.

BACKGROUND: Guidelines recommend hospice care as a treatment option for end-stage heart failure (HF) patients. Little is known regarding utilization of hospice care in a contemporary cohort of patients hospitalized with HF and how this may vary by estimated mortality risk. METHODS: We analyzed HF patients ≥65 years (n = 58,330) from 214 hospitals participating in the Get With the Guidelines-HF program. Univariate analysis comparing patients discharged to hospice versus other patients was performed. Hospice utilization was evaluated for deciles of estimated 90-day mortality risk using a validated model. Multivariate analysis using admission patient and hospital characteristics was also performed to determine factors associated with hospice discharge. RESULTS: There were 1,442 patients discharged to hospice, and rates of referral varied widely by hospital (interquartile range 0-3.7%) as shown in the univariate analysis. Patients discharged to hospice were significantly older and more often white, had lower left ventricular ejection fraction, higher B-type natriuretic peptide, and lower systolic blood pressure on admission. Utilization rates for each decile of 90-day estimated mortality risk ranged from 0.3% to 8.6%. Multivariable analysis found that factors associated with hospice utilization included increased age, low systolic blood pressure on admission, and increased blood urea nitrogen. CONCLUSIONS: Hospice utilization remains low among HF patients, even those with the highest predicted risk of death.

BACKGROUND AND PURPOSE: Mild or rapidly improving stroke is a frequently cited reason for not giving intravenous recombinant tissue-type plasminogen activator (rtPA), but some of these patients may have poor outcomes. We used data from a large nationwide study (Get With The Guidelines-Stroke) to determine risk factors for poor outcomes after mild or improving stroke at hospital discharge. METHODS: Between 2003 and 2009, there were 29,200 ischemic stroke patients (from 1092 hospitals) arriving within 2 hours after symptom onset with mild or rapidly improving stroke symptoms as the only contraindication to rtPA. Logistic regression was used to determine the independent predictors of discharge to home. RESULTS: Among 93,517 patients arriving within 2 hours, 31.2% (29,200) did not receive rtPA solely because of mild/improving stroke. Among the 29,200 mild/improving cases, 28.3% were not discharged to home, and 28.5% were unable to ambulate without assistance at hospital discharge. The likelihood of home discharge was strongly related to initial National Institutes of Health Stroke Scale score (P<0.001). In multivariable-adjusted analysis, patients not discharged to home were more likely to be older, female, and black; have a higher National Institutes of Health Stroke Scale score and vascular risk factors; and were less likely to be taking lipid-lowering medication before admission. CONCLUSIONS: In this large, nationwide study, a sizeable minority of patients who did not receive intravenous rtPA solely because of mild/improving stroke had poor short-term outcomes, raising the possibility that stroke-related disability is relatively common, even in "mild" stroke. A controlled trial of reperfusion therapy in this population may be warranted.

BACKGROUND: Although Hispanics constitute the largest minority in the United States, it is unknown whether regional differences in quality of care and outcomes exist among Hispanic patients hospitalized with acute myocardial infarction (MI). METHODS: Using the GWTG-CAD Registry, clinical characteristics, conformity with quality measures, and in-hospital outcomes were assessed among Hispanic patients from different geographic regions admitted for acute MI in participating hospitals. RESULTS: A total of 11,299 Hispanic patients treated for acute MI at 277 hospitals from 4 regions were included in the study. Midwestern Hispanics were more likely to be younger, with male predominance in all regions. Northeastern Hispanics were more often insured with Medicaid. All subgroups showed high rates of hypertension, dyslipidemia, diabetes, and smoking, with the highest rates observed in the northeast region. Northeastern Hispanics were more likely to be discharged on angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, ß-blockers, and statin or other lipid-lowering therapy. No significant regional differences were observed in aspirin, clopidogrel, and guideline-recommended door-to-balloon and door-to-thrombolysis times. Although Hispanics in the south and northeast were more likely to have a longer hospital stay compared with the west, there were no regional differences in in-hospital mortality. CONCLUSIONS: Among Hispanics with acute MI enrolled in the GWTG-CAD program, there were modest regional differences in clinical profile; high rates of use and, with few exceptions, no regional differences in guideline-recommended therapies; and no regional variation in in-hospital mortality.

Background There is disagreement in the literature about the relationship between strokes and seasonal conditions. We sought to (1) describe seasonal patterns of stroke in the United States, and (2) determine the relationship between weather variables and stroke outcomes. Methods and Results We performed a cross-sectional study using Get With The Guidelines-Stroke data from 896 hospitals across the continental United States. We examined effects of season, climate region, and climate variables on stroke outcomes. We identified 457 638 patients admitted from 2011 to 2015 with ischemic stroke. There was a higher frequency of admissions in winter (116 862 in winter versus 113 689 in spring, 113 569 in summer, and 113 518 in fall; P<0.0001). Winter was associated with higher odds of in-hospital mortality (odds ratio [OR] 1.08 relative to spring, confidence interval [ CI ] 1.04-1.13, P=0.0004) and lower odds of discharge home ( OR 0.92, CI 0.91-0.94, P<0.0001) or independent ambulation at discharge ( OR 0.96, CI 0.94-0.98, P=0.0006). These differences were attenuated after adjusting for climate region and case mix and became inconsistent after controlling for weather variables. Temperature and precipitation were independently associated with outcome after multivariable analysis, with increases in temperature and precipitation associated with lower odds of mortality ( OR 0.95, CI 0.93-0.97, P<0.0001 and OR 0.95, CI 0.90-1.00, P=0.035, respectively). Conclusions Admissions for ischemic stroke were more frequent in the winter. Warmer and wetter weather conditions were independently associated with better outcomes. Further studies should aim to identify sensitive populations and inform public health measures aimed at resource allocation, readiness, and adaptive strategies.

Background Patients presenting to hospitals during non-weekday hours experience worse outcomes, often attributed to reduced staffing. The American Heart Association International Stroke Conference ( ISC ) is well attended by stroke clinicians. We sought to determine whether patients with acute ischemic stroke ( AIS ) admitted during the ISC receive less guideline-adherent care and experience worse outcomes. Methods and Results We performed a retrospective cohort study of US hospitals participating in Get With The Guidelines-Stroke and assessed use of intravenous tissue plasminogen activator, other quality measures, and outcomes for patients with AIS admitted during the ISC compared with those admitted the weeks before and after the conference. A total of 69 738 patients with AIS were included: mean age, 72 years; 52% women; 29% nonwhite. There was no difference between the average weekly number of AIS cases admitted during ISC weeks versus non- ISC weeks (1984 versus 1997; P=0.95). Patient and hospital characteristics were similar between ISC and non- ISC time periods. There were no significant differences in 14 quality metrics and 5 clinical outcomes between patients with AIS treated during the ISC versus non- ISC weeks. Patients with AIS who presented within 2 hours of onset had no difference in the likelihood of receiving intravenous tissue plasminogen activator within 3 hours (adjusted odds ratio, 0.89; 95% confidence interval, 0.77-1.03; P=0.13) or the likelihood of receiving intravenous tissue plasminogen activator within 60 minutes of arrival (adjusted odds ratio, 0.92; 95% confidence interval, 0.83-1.02; P=0.13). Conclusions Patients with acute stroke admitted to Get With The Guidelines-Stroke hospitals during ISC received the same quality care and had similar outcomes as patients admitted at other times.

BACKGROUND: The Centers for Medicare & Medicaid Services rewards hospitals that have low 30-day riskstandardized mortality rates (RSMR) for heart failure (HF). OBJECTIVE: To describe the use of early comfort care for patients with HF, and whether hospitals that more commonly initiate comfort care have higher 30-day mortality rates. DESIGN: A retrospective, observational study. SETTING: Acute care hospitals in the United States. PATIENTS: A total of 93,920 fee-for-service Medicare beneficiaries admitted with HF from January 2008 to December 2014 to 272 hospitals participating in the Get With The Guidelines-Heart Failure registry. EXPOSURE: Early comfort care (defined as comfort care within 48 hours of hospitalization) rate. MEASUREMENTS: A 30-day RSMR. RESULTS: Hospitals' early comfort care rates were low for patients admitted for HF, with no change over time (2.5% to 2.6%, from 2008 to 2014, P = .56). Rates varied widely (0% to 40%), with 14.3% of hospitals not initiating comfort care for any patients during the first 2 days of hospitalization. Risk-standardized early comfort care rates were not correlated with RSMR (median RSMR = 10.9%, 25th to 75th percentile = 10.1% to 12.0%; Spearman's rank correlation = 0.13; P = .66). CONCLUSIONS: Hospital use of early comfort care for HF varies, has not increased over time, and on average, is not correlated with 30-day RSMR. This suggests that current efforts to lower mortality rates have not had unintended consequences for hospitals that institute early comfort care more commonly than their peers.
