Air medical transport for acute ischemic stroke patients: a retrospective cohort study of national trends over an 8-year period.
This study examined patterns of air transport for acute ischemic stroke patients over a period of 8 years (2007-2014). The authors abstracted a 20% national sample of Medicare data from patients ≥ 66 years of age hospitalized with a primary diagnosis of acute ischemic stroke who presented to the emergency department by ambulance (air or ground). They analyzed data from 149,751 hospitalized stroke patients who had a mean age of 81.6 years (standard deviation = 8.0 years), 62.1% female (n = 93,007), and 86.3% White (n = 129,268). Of these, 3.7% used any form of air ambulance. Air ambulance use (2007: 2.5%, 2014: 4.9%) and arrival at certified stroke centers (2007: 40.3%, 2014: 63.2%) increased over time. Air ambulance use was less likely among older patients (76-85 years and >85 years vs. 66-75 years; odds ratio [OR] = 0.68 and OR = 0.34, respectively) and all racial minorities except American Natives (OR = 2.07) and more likely among sicker patients (Charlson Comorbidity Index ≥ 2 vs. 1, OR = 1.23) and rural residents (OR = 1.34). After adjustment for covariates, air ambulance use was associated with higher odds of thrombolysis (adjusted OR = 2.57).

Insurance-based disparities in stroke center access in california: a network science approach.
The purpose of this study was to examine whether there is a relationship between ischemic stroke patient insurance and probability of transfer to a stroke center overall as well as whether hospital cluster modified the relationship between insurance and likelihood of stroke center transfer. The study included 332,995 total ischemic stroke encounters, with 3.5% transferred from the initial ED. The study found that of 52,316 participants presenting to a non-stroke center, 7.1% were transferred. Compared to privately insured patients, there were lower odds of transfer and of transfer to a stroke center among all groups. Within the 14 identified hospital clusters, there was variation in insurance-based disparities in transfer. The largest hospital was also the lowest performing cluster which fully explained the insurance-based disparity in odds of stroke center transfer. The study concluded that uninsured patients had lower stroke center access through transfer than patients with insurance, with the variation primarily explained by patterns in 1 specific hospital cluster.

The pre-adaptation of a stroke-specific self-management program among older adults.
To understand the management of multimorbidity in aging stroke survivors and to examine the complex relationships between comorbidities, researchers used visual analytics to identify patient subgroup. Five significant subgroups of comorbidities such as obesity and cancer were identified. An interdisciplinary team constructed six vignettes that highlighted multimorbidity to customize a self-management program that fitted the needs of older adult stroke survivors.

Initiation of oral anticoagulation in US older adults newly diagnosed with atrial fibrillation during hospitalization.
This study investigated prevalence of oral anticoagulant initiation for newly diagnosed US older adults with atrial fibrillation within 7 days of hospital discharge. The authors used a 20% national sample of Medicare fee-for-service beneficiaries, identifying patients aged 65 years or older newly diagnosed with atrial fibrillation while hospitalized in 2016. Among 38,379 older adults newly diagnosed with atrial fibrillation while hospitalized (mean age 78.2; 51.8% female; 83.3% white), 36,633 (95.4%) had an indication for anticoagulation and 24.6% (9011) of those initiated an oral anticoagulant following discharge. Higher CHA(2) DS(2) -VASc score was associated with a small increase in oral anticoagulant initiation (predicted probability 20.5% for scores <2 and 24.9% for ≥4). Elevated HAS-BLED score was associated with a small decrease in probability of anticoagulant initiation (25.4% for score <2 and 23.1% for ≥3). Frailty was associated with decreased likelihood of oral anticoagulant initiation (24.7% for non-frail and 18.1% for moderately-severely frail). Anticoagulant initiation varied by primary reason for hospitalization, with predicted probability highest among patients with a primary diagnosis of atrial fibrillation (46.1%) and lowest among those with non-cardiovascular conditions (13.8%) and bleeds (3.6%).

Impact of clinician training background and stroke location on bedside diagnostic test accuracy in the acute vestibular syndrome - a meta-analysis.
Researchers conducted a systematic review to assess the accuracy of bedside diagnosis of acute dizziness/vertigo to differentiate peripheral vestibular from central neurologic causes. Their review indicated that the Head Impulse, Nystagmus, Test of Skew (HINTS) examination by trained clinicians can differentiate peripheral from central causes and show higher diagnostic accuracy for stroke in the first 24-48 hours than MRI diffusion-weighted imaging. They concluded that these techniques should be disseminated to clinicians evaluating dizziness/vertigo.

Thoracoabdominal aortic aneurysm life-altering events following endovascular aortic repair in the Vascular Quality Initiative.
This study’s objective was to examine the rates of postoperative mortality and morbidity stratified by type of endovascular aortic aneurysm repair (EVAR). The authors identified all patients who underwent EVAR in the Vascular Quality Initiative registry from January 2011 to May 2022. Patients were then stratified by repair type: infrarenal EVAR, complex EVAR, thoracic endovascular aortic repair (TEVAR), extent I to III thoracoabdominal aortic aneurysm (TAAA) repair, or aortic arch repair. Primary outcomes across the different treatment groups was postoperative thoracoabdominal aortic aneurysm life-altering events (TALE). They identified a total of 52,592 EVARs, 3768 complex EVARs, 3899 TEVARs, 1139 extent I to III TAAA repairs, and 479 arch repairs, with TALE observed in 1.2% of EVARs, 4.8% of complex EVARs, 6.0% of TEVARs, 10% of extent I to III TAAA repairs, and 14% of arch repairs. More proximal landing zone was associated with higher odds of TALE after complex EVAR, TEVAR, and extent I to III TAAA repair. Aortic diameter >65 mm was associated with higher odds of TALE after infrarenal EVAR, complex EVAR, TEVAR, and arch repair. The use of parallel grafting technique (chimney/snorkel/periscope) during extent I to III TAAA repair was also associated with higher odds of TALE. Preoperative chronic kidney disease was also associated with higher odds of TALE after infrarenal EVAR, complex EVAR, TEVAR, and extent I to III TAAA repair.

Association of direct oral anticoagulation management strategies with clinical outcomes for adults with atrial fibrillation.
This study investigated the impact of an anticoagulation management service (AMS) on clinical outcomes of adults with atrial fibrillation (AF). This retrospective cohort study was conducted in 3 Kaiser Permanente regions, with each region taking a slightly different approach to direct oral anticoagulant (DOAC) care. These approaches included (1) usual care (UC) by the prescribing clinician, (2) UC plus an automated population management tool (PMT), or (3) pharmacist-managed AMS care. The study included 44,746 adults with a diagnosis of AF who initiated DOAC or warfarin between August 2016 and January 1, 2020, 6182 in the UC model, 33,624 in the UC plus PMT care model, and 4939 in the AMS care model. Baseline characteristics (mean age, 73.1 years, 56.1% male, 67.2% non-Hispanic White, median CHA2DS2-VASc [congestive heart failure, hypertension, age ≥75 years, diabetes, stroke, vascular disease, age 65-74 years, female sex] score of 3 [IQR, 2-5]) were well balanced after inverse probability of treatment weighting (IPTW). The cohort was followed over a median of 2 years, and patients who received the UC plus PMT or AMS care model did not have significantly better outcomes than those who received only UC.

Distal embolic protection use during transfemoral carotid artery stenting is associated with improved in-hospital outcomes.
Researchers sought to assess in-hospital outcomes in patients who had undergone transfemoral carotid artery stenting (tfCAS) with and without embolic protection using a distal filter. Patients undergoing tfCAS were identified in the Vascular Quality Initiative and those who received proximal embolic balloon protection were excluded. Outcomes of interest were stroke, death, composite stroke/death, myocardial infarction, transient ischemic attack, and hyperperfusion syndrome. Results indicated that tfCAS performed without attempted distal embolic protection was associated with higher risk of in-hospital stroke and death; tfCAS after a failed attempt at filter placement had equivalent stroke/death to patients with no filter attempted, but higher risk of stroke/death compared with those with successfully placed filters. The researchers concluded that these findings support current Society for Vascular Surgery guidelines and, if a filter cannot be safely placed, alternative approaches to carotid revascularization should be considered.

Efficacy and safety of single versus dual antiplatelet therapy in carotid artery stenting.
This study’s objective was to examine the efficacy and safety of preoperative single antiplatelet therapy (AP) therapy vs double antiplatelet therapy (DAPT) in patients who had undergone transfemoral CAS (tfCAS) or transcarotid artery revascularization (TCAR). The authors identified all patients who had undergone tfCAS or TCAR in the Vascular Quality Initiative database from 2016 to 2021. A total of 18,570 tfCAS patients were included, of which 70% had received DAPT, 5.6% no AP therapy, 10% ASA only, 8.0% ASA + AP loading dose, 4.6% P2Y12 inhibitor (P2Yi) only, and 2.9% P2Yi + AP loading dose. After adjustment, compared with DAPT, the incidence of stroke/death was higher with no AP therapy, ASA only, and ASA + AP loading dose, but was similar with P2Yi only, and P2Yi + AP loading dose. No differences were found in the incidence of bleeding rates between the treatment groups after tfCAS or TCAR. These findings support the current guidelines recommending DAPT before CAS but also suggest that P2Yi monotherapy might confer thromboembolic benefits similar to those with DAPT.

Risk assessment of the acute stroke diagnostic process using failure modes, effects, and criticality analysis.
The authors conducted a failure modes, effects, and criticality analysis (FMECA) of the emergency department (ED)-based acute stroke diagnostic process at three health systems in Chicago. The FMECA was designed to identify and rank order failures in the processes of care. The authors found that failure to use existing screening scales to identify patients with large-vessel occlusions early in the ED course ranked highest; other highly ranked failures were obtaining an accurate history of the index event, suspecting acute stroke in triage, and using established stroke screening tools at ED arrival to identify potential stroke patients. They concluded that these results highlight the crucial importance of the first steps in the diagnostic process.

Impact of Medicare eligibility on informal caregiving for surgery and stroke.
The purpose of this study was to assess whether the intensity of family and friend care changes after older individuals enroll in Medicare at 65. Researchers used Health and Retirement Study survey data covering a 20-year period to compare informal care received by patients who had been hospitalized for stroke, heart surgery, or joint surgery, and who were stratified into propensity-weighted pre- and post-Medicare eligibility cohorts. Their results showed that onset of Medicare eligibility was associated with a substantial decrease in family and friend caregiving use received by stroke patients, but not in the other acute care cohorts. They concluded that this effect of Medicare coverage on informal caregiving had implications for patient function and caregiver burden, and should be considered in episode-based reimbursement models that alter professional rehabilitative care intensity.

Statin therapy is associated with improved perioperative outcomes and long-term mortality following carotid revascularization in the Vascular Quality Initiative.
This study evaluated the outcomes of carotid artery stenosis (CAS) patients using statin therapy before undergoing carotid revascularization in the Vascular Quality Initiative registry. The authors identified all patients who underwent carotid endarterectomy (CEA), transfemoral carotid artery stenting (tfCAS), or transcarotid artery revascularization (TCAR) in the Vascular Quality Initiative registry from January 2016 to September 2021. Compared with statin use, no statin use was associated with a higher risk of in-hospital stroke or death and 5-year mortality among CEA and tfCAS patients, although there was no significant difference in outcomes among TCAR patients.

Comparison of functional status improvements among patients with stroke receiving postacute care in inpatient rehabilitation vs skilled nursing facilities.
This cohort study compared functional status improvements of poststroke patients who either went to an inpatient rehabilitation facility (IRF) or a skilled nursing facility (SNF). The study used data from Medicare claims for stroke from January 2013 through November 2014. A total of 99,185 patients were studied. Patients admitted to SNFs tended to be older, female, and had a longer hospital length of stay than those admitted to IRFs. Stroke patients admitted to IRFs had larger improvements for mobility score points and for self-care on admission compared with those admitted to SNFs. There was found to be no statistical difference in the odds of 30- to 365-day mortality.

Patients with greater stroke severity and premorbid disability are less likely to receive therapist consultations and intervention during acute care hospitalization.
The goal of this single-center longitudinal observational study was to estimate the proportion of and factors associated with receipt of therapist consultations and interventions during acute care hospitalization following ischemic and hemorrhagic stroke. Findings showed that approximately 1 in 4 study participants with acute stroke received neither a consultation nor an intervention. The authors conclude that efforts to improve the delivery of acute care therapy services are needed to optimize care for these people.

Social network structure in young stroke survivors with aphasia: a case series report.
The purpose of this study was to profile the social networks of four young adult stroke survivors with aphasia. Results showed that pre-stroke friendships were dissolved or reduced at the onset of aphasia. The most impaired persons with aphasia spent most of their days in isolation without a consistent communication partner. This study result suggests that young adult stroke survivors with aphasia have significant changes in their social network structure after stroke, but it is unclear if the observed change in social network structure is more related to age or level of communication impairment.

Role of diabetes and insulin use in the risk of stroke and acute myocardial infarction in patients with atrial fibrillation: a Medicare analysis.
This study examined the role of diabetes and insulin use in the risk of stroke and acute myocardial infarction (AMI) in patients with atrial fibrillation (AF). A cohort of Medicare beneficiaries newly diagnoses with AF from 2011 to 2013 were identified. The cohort was divided into those with diabetes requiring insulin (6.7%), those with diabetes not requiring insulin (31.3%) and non-diabetics (62%). Diabetics requiring insulin were at the greatest risk of stroke and AMI, and diabetics not requiring insulin were at slightly lower risk, but non-diabetics had the lowest risk.

Evaluation of the experience of spoke hospitals in an academic telestroke network.
Implementation of telestroke has been associated with improved thrombolysis rates and clinical outcomes in remote or neurologically underserved spoke hospitals. Yet, the experience of spoke hospitals using telestroke has not been well described. In this study, the investigators sought to characterize spoke hospitals' perceptions of telestroke to understand perceived advantages, challenges, and barriers to use.

Stroke survivors' perspectives on post-acute rehabilitation options, goals, satisfaction, and transition to home.
This study analyzed stroke survivors’ perspectives on post-acute rehabilitation involvement with their care during discharge planning. Researchers interviewed eighteen stroke survivors who were sent to inpatient rehabilitation facilities after a stroke. They were surveyed about their involvement in decisions made in the selection of their rehabilitation facilities, and more than half were not. About two-thirds of patients were not involved in rehabilitation goal setting. However, most patients were satisfied with their rehabilitation stay.

Home-time is a patient-centered outcome variable for stroke: an executive summary.
An outcome measure to assess functional recovery after stroke that is easily obtainable and meaningful to the patient can be very useful for assessing risks and benefits of therapeutic strategies. Home-time, which is defined as the total number of days spent alive by the patient at home, outside healthcare institutions after discharge from an index stroke event, is such a measure, and is discussed in this paper.

Changes in use of postacute care associated with accountable care organizations in hip fracture, stroke, and pneumonia hospitalized cohorts.
In this study, researchers examined changes in more and less discretionary condition-specific postacute care use associated with Medicare accountable care organization (ACO) implementation. They found that ACOs decreased spending on postacute care by decreasing use of discretionary services. In addition, ACO implementation was associated with reduced length of stay in skilled nursing facilities, while hip fracture patients used institutional postacute settings at higher rates. The authors also observed decreases in spending, readmission days, and mortality among pneumonia patients.

In this paper, researchers studied low baseline plasma 25-hydroxyvitamin D (25(OH)D) and its association with long-term risk of sepsis. Data from the Reasons for Geographic and Racial Differences in Stroke study was used. Findings reveals that, among community-dwelling US adults, low plasma 25(OH)D measured at a time of relative health was independently associated with increased risk of sepsis.

Design and implementation of structured clinical documentation support tools for treating stroke patients.
This article describes the development of a customized structured clinical documentation toolkit that standardizes patient data collection to conform to Best Practices for treating patients with stroke. The toolkit collects demographic information for patients, relevant score test measures, and information on disability, treatment, and outcomes. Basic descriptive data gathered via the toolkits is provided and their utility in collecting patient data in a manner that supports both quality clinical care and research initiatives demonstrated. Quality improvement projects and current research initiatives using the toolkit are also discussed.

Frailty syndrome and risk of sepsis in the REasons for Geographic And Racial Differences in Stroke (REGARDS) cohort.
This study examined the association between frailty (weakness, exhaustion, and low physical activity) and the risk of sepsis in stroke patients. Data from the cohort study Reasons for Geographic and Racial Differences in Stroke (REGARDS) was used. There was an associated increase in sepsis hospitalizations and 30-day case fatalities from sepsis in stroke patients with more frailty indicators.
