Introduction: The COVID-19 pandemic has wreaked havoc on the presentation, care and outcomes of patients with acute cerebrovascular and cardiovascular conditions. We sought to measure the national impact of COVID-19 on the care for acute ischemic stroke (AIS) and acute myocardial infarction (AMI). Methods: In this retrospective, observational study, we used the Premier Healthcare Database to evaluate the changes in the volume of care and hospital outcomes for AIS and AMI in relation to the pandemic. The pandemic months were defined from March 1, 2020- April 30, 2020 and compared to the same period in the year prior. Outcome measures were volumes of hospitalization and reperfusion treatment for AIS and AMI (including intravenous thrombolysis [IVT] and/or mechanical thrombectomy [MT] for AIS and percutaneous coronary interventions [PCI] for AMI) as well as in-hospital mortality, hospital length of stay (LOS) and hospitalization costs were compared across a 2-month period at the height of the pandemic versus the corresponding period in the prior year. Results: There were 95,453 AIS patients across 145 hospitals and 19,744 AMI patients across 126 hospitals. There was a significant nation-wide decline in the absolute number of hospitalizations for AIS (-38.94%;95%CI,-34.75% to -40.71%) and AMI (-38.90%;95%CI,-37.03% to -40.81%) as well as IVT (-30.32%;95%CI,-27.02% to -33.83%), MT (-23.54%;95%CI,-19.84% to -27.70%), and PCI (-35.05%;95%CI,-33.04% to -37.12%) during the first two months of the pandemic. This occurred across low-, mid-, and high-volume centers and in all geographic regions. Higher in-hospital mortality was observed in AIS patients (5.7% vs.4.2%, p=0.0037;OR 1.41,95%CI 1.1-1.8) but not AMI patients. A shift towards an increase in the proportion of admitted AIS and AMI patients receiving reperfusion therapies suggests a greater clinical severity among patients that were hospitalized for these conditions during the pandemic. A shorter length of stay (AIS: -17%, AMI: -20%), and decreased hospitalization costs (AIS: -12%, AMI: -19%) were observed. Conclusions: Our findings shed light on the combined health outcomes and economic impact the COVID-19 pandemic has had on acute stroke and cardiac emergency care.

Introduction: There are limited contemporary data on prevalence and outcomes of acute ischemic stroke (AIS) complicating acute myocardial infarction (AMI). Methods: Adult (>18 years) AMI admissions using the National Inpatient Sample database (2000-2017) were evaluated for in-hospital AIS. Outcomes of interest included in-hospital mortality, hospitalization costs, length of stay, and use of tracheostomy and percutaneous endoscopic gastrostomy (PEG). The discharge destination was used to classify AIS survivors into good and poor functional outcomes with poor (moderate to severe disability) defined as discharge to extended care facility including short-term hospital/rehabilitation facility, intermediate care or long-term care facilities. Results: Of a total 11,622,528 AMI admissions, 183,896 (1.6%) had concomitant AIS. Over the 18-year period, AIS rates were stable in STEMI admissions and decreased in NSTEMI (p<0.001). Compared to those without, the AIS cohort was on average older, female, of non-White race, with greater comorbidities, and higher rates of arrhythmias. The AMI-AIS admissions received less frequent coronary angiography (46.9% vs. 63.8%) and percutaneous coronary angiography (22.7% vs 41.8%) (p<0.001). Female sex, non-White race, higher comorbidity, ST-segment-elevation AMI presentation, atrial fibrillation/flutter, use of mechanical circulatory support and invasive mechanical ventilation were identified as individual predictors of AIS after AMI. The AIS cohort had higher in-hospital mortality (16.4% vs. 6.0%; adjusted OR 1.75 [95% CI 1.72-1.78]; p<0.001) with a steady decrease in the adjusted in-hospital mortality in over the 18-year period (21% in 2000 vs 17% in 2017). The AIS cohort had longer hospital length of stay, higher hospitalization costs, greater use of tracheostomy and PEG, and less frequent discharges to home (all p<0.001). In AMI-AIS survivors (N=153,318), 57.3% had a poor functional outcome with temporal trends showing a slight increase in recent years (57% in 2000 vs 62% in 2017). Conclusions: AIS is associated with significantly higher in-hospital mortality and poor functional outcomes in AMI admissions. Despite improvement in in-hospital mortality, poor functional outcomes remain high.

The Impact

Background: Intravenous thrombolysis with recombinant tissue plasminogen activator (rtPA) is an effective treatment of acute ischemic stroke (AIS). The safety of intravenous rtPA in patients with thrombocytopenia is unclear. This study sought to evaluate the impact of thrombocytopenia on in-hospital outcomes in patients with AIS who received intravenous thrombolysis. Methods: This was a retrospective study using the 2012–2014 National Inpatient Sample (20% stratified sample of US hospitals). The study identified adult patients admitted with AIS who received intravenous rtPA during hospitalization. The identified admissions were stratified into 2 cohorts based on the presence or absence of thrombocytopenia. Multilevel, multivariate regression analysis and propensity matching were performed to evaluate in-hospital mortality, length of stay, and in-hospital complications. Results: Of 101,527 patients admitted for AIS and received intravenous rtPA from 2012 to 2014, 3,520 (3.47%) had thrombocytopenia. In-hospital mortality was 10.8 vs. 6.9% in patients with and without thrombocytopenia in original data, p < 0.001. In-hospital length of stay was significantly higher in the thrombocytopenia group (5.9 vs. 8.2 days, p < 0.001). The differences were significant in both the multivariate regression model and the propensity score matching model. Patients with thrombocytopenia also had a statistically higher incidence of intracranial hemorrhage, postprocedural bleeding, blood transfusion, tracheotomy, and mechanical ventilation. Conclusion: Thrombocytopenia is associated with higher in-hospital mortality, longer length of stay, a higher incidence of intracranial hemorrhage, postprocedural bleeding, and mechanical ventilation in stroke patients who received intravenous rtPA.

Introduction: There is a paucity of contemporary data on the burden of intracranial hemorrhage (ICH) complicating acute myocardial infarction (AMI). Methods: The National Inpatient Sample database (2000 to 2017) was used to evaluate in-hospital burden of ICH in adult (>18 years) AMI admissions. In-hospital mortality, hospitalization costs, length of stay, and measure of functional ability were the outcomes of interest. The discharge destination along with use of tracheostomy and percutaneous endoscopic gastrostomy (PEG) were used to estimate functional burden. Results: Of a total 11,622,528 AMI admissions, 23,422 (0.2%) had concomitant ICH. Compared to those without, admissions with ICH were on average older, female, of non-White race, with greater comorbidities, and higher rates of arrhythmias (all p<0.001). Female sex, non-White race, ST-segment-elevation AMI presentation, use of fibrinolytics, mechanical circulatory support and invasive mechanical ventilation were identified as individual predictors of ICH. The AMI admissions with ICH received less frequent coronary angiography (46.9% vs. 63.8%), percutaneous coronary intervention (22.7% vs. 41.8%), and coronary artery bypass grafting (5.4% vs. 9.2%) as compared to those without (all p<0.001). ICH was associated with a significantly higher in-hospital mortality (41.4% vs. 6.1%; adjusted OR 5.65 [95% CI 5.47-5.84]; p<0.001), and adjusted temporal trends showed a steady decrease in in-hospital mortality over the 18-year period (Figure 1A). AMI-ICH admissions also had longer hospital length of stay, higher hospitalization costs, and greater use of PEG (all p<0.001). In AMI-ICH survivors (N=13, 689), 81.3% had a poor functional outcome indicating severe morbidity and temporal trends revealed a slight increase over the study period (Figure 1B). Conclusions: ICH causes a substantial burden in AMI due to associated higher in-hospital mortality, resource utilization, and poor functional outcomes.

Thrombolytic Treatment

BACKGROUND: Despite the recent emphasis on protocols for emergent triage and treatment of in-hospital acute ischemic stroke, there is little data on rates and outcomes of patients receiving thrombolytics for in-hospital ischemic strokes. OBJECTIVE: To determine the rates of in-hospital ischemic stroke treated with thrombolytics and to compare outcomes with patients treated with thrombolytics on admission. DESIGN/METHODS: We analyzed a seven-year data (2002-2009) from the National Inpatient Survey (NIS), a nationally representative inpatient database in the United States. We identified patients who had in-hospital ischemic strokes (defined by thrombolytic treatment after one day of hospitalization) and those who received thrombolytics on the admission day. We compared demographics, baseline clinical characteristics, in hospital complications, length of stay, hospitalization charges, and discharge disposition, between the two patient groups. RESULT: A total of 18036 (21.5%) and 65912 (78.5%) patients received thrombolytics for in-hospital and on admission acute ischemic stroke, respectively. In hospital complications such as pneumonia (5.0% vs. 3.4%, p=0.0006), deep venous thrombosis (1.9% vs. 0.6%, p<0.0001) and pulmonary embolism (0.8% vs. 0.4%, p=0.01) were significantly higher in the in-hospital group compared to on admission thrombolytic treated group. Hospital length of stay and mean hospital charges were not different between the two groups. Patients who had in-hospital strokes had had higher rates of in hospital mortality (12.1% vs. 10.6%, p=0.02). In a multivariate analysis, in-hospital thrombolytic treated group had higher in-hospital mortality after adjustment for age, gender and baseline clinical characteristics (odds ratio 0.84, 95% confidence interval 0.74-0.95, p=0.008). CONCLUSION/RELEVANCE: In current practice, one out of every five acute ischemic stroke patients treated with thrombolytics is receiving treatment for in-hospital strokes. The higher mortality and complicated hospitalization in such patients needs to be recognized.

Background and objectives: There are limited data on racial differences in clinical and economic outcomes of acute ischemic stroke (AIS) hospitalizations in the US. We sought to ascertain the effect of race on AIS outcomes in a population based retrospective cohort study. Methods: We used the 2012 National Inpatient Sample (NIS), which is the largest database of inpatient stays in the US, to identify cases of AIS using ICD9-CM codes 433.01, 433.11, 433.21, 433.31, 433.81, 433.91, 434.01, 434.11, 434.91 and 437.1 in patients >=18 years of age. Cases with missing data on race were excluded (5% of study sample). Primary outcome was in-hospital mortality. Secondary outcomes included proportion receiving endovascular mechanical thrombectomy (EMT) or thrombolysis, mean inflation adjusted charges and length of stay. Linear and logistic regression was used to test differences in continuous and categorical outcomes respectively. Survey techniques were used for all analyses. Results: There were 452, 330 hospitalizations for AIS in patients >=18 years in 2012. In univariate logistic regression using race as predictor, in-hospital mortality was significantly lower for Blacks (p<0.001), Hispanics (p=0.025) and Native Americans (p=0.047) compared to Whites. However, after adjusting for age, sex, Charlson comorbidity index, EMT and thrombolysis only blacks had a significantly lower mortality compared to whites (OR 0.74, 95% CI 0.66 - 0.82, p<0.001). Black patients were less likely to receive thrombolysis (OR 0.87, 95% CI 0.79 - 0.95; p=0.003) whereas Asian or Pacific Islanders were more likely to receive thrombolysis (OR 1.20, 95% CI 1.01 - 1.44; p=0.043) compared to whites. There was no difference in rates of EMT by race (p=0.18). Total charges and length of stay were significantly higher in racial minorities compared to whites (table). Conclusions: Blacks hospitalized for AIS have significantly lower in-hospital mortality compared to whites but are significantly less likely to receive thrombolysis compared to whites. Total charges and length of stay are significantly higher for racial minorities. Future studies should investigate mechanisms of this apparent protective effect of black race on in-hospital mortality in AIS.

Background: As is seen in the early door-to-needle times of intravenous thrombolysis in the treatment of acute ischemic stroke (AIS), prior endovascular management trials have demonstrated early revascularization can lead to improved outcomes. We aimed to study the relationship of the time from acute stroke onset to the time of arterial groin puncture (OTP) as a possible predictor of successful revascularization. Methods: We retrospectively analyzed 149 patients who presented to our hospital with AIS and underwent emergent endovascular treatment from January 1, 2008 to March 31, 2011. Charts were reviewed for baseline characteristics, OTP times, and endovascular therapies employed. Primary outcomes included successful revascularization (TIMI 2 to 3 flow), improvement of baseline NIHSS ≥ 4, symptomatic ICH (increase of NIHSS ≥ 4), in-hospital mortality, and mRS two or less at discharge. We excluded patients with OTP times greater than eight hours to ensure consistency with approved usage of mechanical thrombectomy devices. Independent samples T-tests were performed to determine relationships of OTP with our primary outcomes. Results: Of the 149 patients who underwent endovascular therapy, 120 had OTP times less than eight hours. Of these 120, 44% were male, median age was 73 years (range 17, 93), median baseline NIHSS was 18 (range 5, 28), 53% received intravenous tissue plasminogen activator (tPA), 69% received intra-arterial tPA, and mechanical thrombectomy was performed in 69%. Internal carotid artery occlusions were seen in 32% of patients, 50% had M1 segment occlusions, and only five patients had posterior circulation occlusions. Successful revascularization was achieved in 70% of interventions, 10% of patients had mRS ≤ 2 at discharge, symptomatic hemorrhage was 18%, and in-hospital mortality was 24%. Patients with TIMI 2 to 3 flow had significantly shorter mean OTP times (3.9 vs 4.5 hours; p=0.024). No significant associations of mean OTP times were found with symptomatic hemorrhage rate (4.4 vs 4.0; p=0.628), in-hospital mortality (4.0 vs 4.0; p=0.677), improvement in NIHSS (3.9 vs 4.2; p=0.283), or a mRS ≤ 2 at discharge (3.7 vs 4.1; p=0.185). Conclusions: The recanalization rate in our study is comparable to prior endovascular trials. Patients with OTP times less than 3.9 hours were more likely to result in successful revascularization. Onset to groin puncture did not predict in-hospital mortality, symptomatic hemorrhage, or condition at discharge in our study. Further study is needed to determine if advanced perfusion imaging prior to intervention may impact treatment time and ultimately clinical outcome.

Background To study the relationship between race and outcomes of patients with firearm injuries hospitalized in the United States. Methods The 2016 National Inpatient Sample was used. Patients were included if they had a principal diagnosis of firearm injury. Exclusion criteria were age <16 years and elective admissions. The primary outcome was in-hospital mortality. Secondary outcomes were morbidity (traumatic shock, prolonged mechanical ventilation, acute respiratory distress syndrome [ADRS], and ventilator-associated pneumonia [VAP]), and resource utilization (length of stay and total hospitalization charges and costs). Results The sample included 31 335 patients; 52% were Black and 29% were Caucasian. The mean age was 32 years and 88% were male. Black patients had lower odds of mortality (adjusted odds ratio (aOR): 0.41 (95% CI: 0.32-0.53), P < .01). However, compared with Caucasians, Blacks had higher mean total hospitalization charges (adjusted mean difference (aMD) : $14 052 (CI: $1469-$26 635), P = .03) and costs (aMD: $3248 (CI: $654-$5842), P = .01) despite similar mean length of stay (aMD: 0.70 (CI: −0.05-1.45), P = .07). Both racial groups had similar rates of traumatic shock (aOR: 0.91 (0.72-1.15), P = .44), prolonged mechanical ventilation (aOR: 0.82 (0.63-1.09), P = .17), ARDS (aOR: 1.18 (0.45-3.07), P = .74) and VAP (aOR: 1.27 (0.47-3.41), P = .63). Discussion Black patients with firearm injuries had a lower adjusted odds of in-hospital mortality compared with other races. However, despite having a similar hospital length of stay and in-hospital morbidity, -Black patients had higher total hospitalization costs and charges.

Background: Impaired level of consciousness (LOC) on presentation after acute ischemic stroke (AIS) may affect outcomes and the decision to withdraw life-sustaining treatment (WLST). We aim to investigate the outcomes and their trends after AISby the LOC on stroke presentation. Methods: We studied 238,989 cases with AIS in the Florida Stroke Registry from 2010-2019. Pearson chi-squared and Kruskall-Wallis tests were used to compare descriptive statistics. A multivariable-logistic regression with GEE accounted for basic demographics, comorbidities, stroke severity, location, hospital size and teaching status. Results: At stroke presentation, 32,861 (14%) cases had impaired LOC (mean age 77, 54% women, 60 white%, 19% Black, 16% Hispanic). Compared to cases with preserved LOC, impaired cases were older (77 vs. 72 years old), more women (54% vs. 48%), had more comorbidities, greater stroke severity on NIHSS ≥ 5 (49% vs. 27%), higher WLST rates (3% vs. 0.6%), and greater in-hospital mortality rates (9% vs. 3%). In our adjusted model however, no significant association was found between impaired LOC and in-hospital mortality, or length of stay. Those with preserved LOC were more likely discharged home/rehab (OR 0.7, 95%CI 0.6-0.8, p<0.0001) and more likely to ambulate independently (OR 0.7, 95%CI 0.6-0.9, p=0.001). Trend analysis (2010-2019) showed decreased mortality, increased length of stay, and increased rates of discharge to home/rehab in all irrespective of LOC status. Conclusion: In this large multicenter registry, AIS cases presenting with impaired LOC had more severe strokes at presentation. Although LOC was not associated with significantly worse in-hospital morality, it was associated with higher rates of WLST and more disability among survivors. Future efforts should focus on biomarkers of LOC that discriminates the potential for early recovery and reduced disability in acute stroke patients with impaired LOC.
