Door-in-Door-Out Times at Referring Hospitals and Outcomes of Hemorrhagic Stroke.

STUDY OBJECTIVE: Interhospital transfer is often required in the care of patients with hemorrhagic stroke. Guidelines recommend a door-in-door-out (DIDO) time of ≤120 minutes at the transferring emergency department (ED); however, it is unknown whether DIDO times are related to clinical outcomes of hemorrhagic stroke. METHODS: Retrospective, observational cohort study using US registry data from Get With The Guidelines-Stroke participating hospitals. Patients include those aged ≥18 years with intracerebral hemorrhage (ICH) or subarachnoid hemorrhage (SAH) who were transferred from the ED to a Get With The Guidelines participating receiving hospital from January 1, 2019, to July 31, 2022. The primary outcome was ordinal discharge modified Rankin scale (mRS) score and secondary outcomes included dichotomous discharge mRS, ability to ambulate independently at discharge, and inhospital mortality at the receiving hospital. RESULTS: In all, 19,708 ICH and 7,757 patients with SAH were included. For patients with ICH, an increasing DIDO time was associated with greater odds of mRS 0 to 3 versus 4 to 6 at discharge in the unadjusted analyses (DIDO 91 to 180 minutes, odds ratio [OR] 1.15 [1.04 to 1.27]; DIDO 181 to 270 minutes, OR 1.51 [1.33, 1.71]; DIDO >270 minutes, OR 1.83 [1.58, 2.11]; versus DIDO ≤90 minutes). In the adjusted analyses, no associations were observed. Similar results were seen for mRS at discharge in patients with SAH. In both patients with ICH and SAH, longer DIDO times were associated with greater odds of independent ambulation at discharge and lower odds of inhospital mortality in the unadjusted analyses. After adjustment, the effect sizes of these associations were reduced, with some of the results based on quartiles becoming statistically nonsignificant. CONCLUSION: These findings suggest that EDs currently expedite the transfer of the sickest patients; however, prospective studies and more granular data are needed to understand the impact of early treatment and timing of transfer for patients with hemorrhagic stroke.

Neighborhood Racial and Ethnic Predominance, Child Opportunity, and Violence-Related Mortality among Children and Adolescents in Chicago.

Our objective was to determine whether Child Opportunity Index (COI), a measure of neighborhood socioeconomic and built environment specific to children, mediated the relationship of census tract Black or Hispanic predominance with increased rates of census tract violence-related mortality. The hypothesis was that COI would partially mediate the relationship. This cross-sectional study combined data from the American Community Survey 5-year estimates, the COI 2.0, and the Illinois Violent Death Reporting System 2015-2019 for the City of Chicago. Individuals ages 0-19 years were included. The primary exposure was census tract Black, Hispanic, White, and other race predominance (> 50% of population). The primary outcome was census tract violence-related mortality. A mediation analysis was performed to evaluate the role of COI as a potential mediator. Multivariable logistic regression modeling census tract violence-related mortality demonstrated a direct effect of census tract Black predominance (adjusted odds ratio [aOR] 2.59, 95% confidence interval [CI] 1.30-5.14) on violence-related mortality compared to White predominance. There was no association of census tract Hispanic predominance with violence-related mortality compared to White predominance (aOR 1.57, 95% CI 0.88-2.84). Approximately 64.9% (95% CI 60.2-80.0%) of the effect of census tract Black predominance and 67.9% (95% CI 61.2-200%) of the effect of census tract Hispanic predominance on violence-related mortality was indirect via COI. COI partially mediated the effect of census tract Black and Hispanic predominance on census tract violence-related mortality. Interventions that target neighborhood social and economic factors should be considered to reduce violence-related mortality among children and adolescents.

Emergency Department Process Times and Door-In-Door-Out Times in Interhospital Transfers After Acute Ischemic Stroke.

Importance: Stroke treatment is exquisitely time sensitive. The door-in-door-out (DIDO) time, defined as the total time spent in the emergency department (ED) at a transferring hospital, is an important quality metric for the care of acute stroke. However, little is known about the contributions of specific process steps to delays and disparities in DIDO time. Objective: To quantify process steps and their association with DIDO times at transferring hospitals among patients with acute ischemic stroke (AIS). Design, Setting, and Participants: This retrospective cohort study analyzed patients in the American Heart Association Get With the Guidelines-Stroke registry with AIS presenting between January 1, 2019, to December 31, 2021, and transferred from the presenting hospital ED to another acute care hospital for evaluation of thrombolytics, endovascular therapy, or postthrombolytic care. Data were analyzed from July 8 to October 13, 2023. Exposures: Intervals of ED care of ischemic stroke: door-to-imaging and imaging-to-door times. Main Outcomes and Measures: The primary outcome was DIDO time. Multivariate generalized estimating equations regression models were performed to compare contributions of interval process times to explain variation in DIDO time, controlling for patient- and hospital-level characteristics. Results: Among 28 887 patients (50.5% male; mean [SD] age, 68.3 [14.8] years; 5.5% Hispanic, 14.7% non-Hispanic Black, and 73.2% non-Hispanic White), mean (SD) DIDO time was 171.4 (149.5) minutes, mean (SD) door-to-imaging time was 18.3 (34.1) minutes, and mean (SD) imaging-to-door time was 153.1 (141.5) minutes. In the model adjusting for door-to-imaging time, the following were associated with longer DIDO time: age 80 years or older (compared with 18-59 years; 5.97 [95% CI, 1.02-10.92] minutes), female sex (5.21 [95% CI, 1.55-8.87] minutes), and non-Hispanic Black race (compared with non-Hispanic White 10.09 [95% CI, 4.21-15.96] minutes). In the model including imaging-to-door time as a covariate, disparities in DIDO by age and female sex became nonsignificant, and the disparity by Black race was attenuated (2.32 [95% CI, 1.09-3.56] minutes). Conclusions and Relevance: In this national cohort study of interhospital transfer of patients with AIS, delays in DIDO time by Black race, older age (≥80 years), and female sex were largely explained by the imaging-to-door period, suggesting that future systems interventions should target this interval to reduce these disparities. While existing guidelines and care resources heavily focus on reducing door-to-imaging times, further attention is warranted to reduce imaging-to-door times in the management of patients with AIS who require interhospital transfer.

Disparities in Emergency Medical Services Use, Prehospital Notification, and Symptom Onset to Arrival in Patients With Acute Stroke.

BACKGROUND: Disparities in time to hospital presentation and prehospital stroke care may be important drivers in inequities in acute stroke treatment rates, functional outcomes, and mortality. It is unknown how patient-level factors, such as race and ethnicity and county-level socioeconomic status, affect these aspects of prehospital stroke care. METHODS: Cross-sectional study of patients with ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage in the Get With the Guidelines-Stroke registry, presenting from July 2015 to December 2019, with symptom onset <24 hours. Multivariable logistic regression and quantile regression were used to investigate the outcomes of interest: emergency medical services (EMS) transport (versus private vehicle), EMS prehospital notification (versus no prehospital notification), and stroke symptom onset to time of arrival at the emergency department. Prespecified covariates included patient-level, hospital-level, and county-level characteristics. RESULTS: The inclusion criteria was met by the 606 369 patients. Of the patients, 51.2% were men and 69.9% White, with a median National Institutes of Health Stroke Severity of 4 (IQR, 2-10), and median social deprivation index (SDI) of 51 (IQR, 27-75). Median symptom onset to arrival time was 176 minutes (IQR, 64-565). Black race was significantly associated with prolonged symptom onset to emergency department arrival time (+28.21 minutes [95% CI, 25.59-30.84]), and decreased odds of EMS prehospital notification (OR, 0.80 [95% CI, 0.78-0.82]). SDI was not associated with differences in EMS use but was associated with lower odds of EMS prehospital notification (upper SDI tercile versus lowest, OR, 0.79 [95% CI, 0.78-0.81]). SDI was also significantly associated with stroke symptom onset to emergency department arrival time (upper SDI tercile versus lowest +2.56 minutes [95% CI, 0.58-4.53]). CONCLUSIONS: In this national cross-sectional study, Black race was associated with prolonged onset to time of arrival intervals and significantly decreased odds of EMS prehospital notification, despite similar use of EMS transport. Greater county-level deprivation was also associated with reduced odds of EMS prehospital notification and slightly prolonged stroke symptom onset to emergency department arrival time. Efforts to reduce place-based disparities in stroke care must address significant inequities in prehospital care of acute stroke and continue to address health inequities associated with race and ethnicity.

Lipoprotein(a) among normotensive patients and risk of incident hypertension.

Lipoprotein(a) has been shown to be disruptive to local endothelial cells, whose integrity is critical to blood pressure (BP) regulation. Cross-sectional analysis has shown an association between lipoprotein(a) and prevalent hypertension, though it is unclear if lipoprotein(a) increases risk of incident hypertension. To assess this, the authors measured baseline lipoprotein(a) among 5307 normotensive patients (median age 26 years (interquartile range [IQR] 12-50) and used Cox proportional hazard models to generate hazard rations (HR) with 95% confidence intervals (CI; median follow-up 10-years). The authors categorized lipoprotein(a) as <15 mg/dL, 15-<30 mg/dL, 30-50 mg/dL, >50 mg/dL, and performed subgroup analysis of adults >50 years at baseline. Incident hypertension was defined as a measured BP ≥140/90 mm Hg or a new ICD-9/10 code. After adjustment, hypertension for patients with baseline lipoprotein(a) 15-<30 mg/dL, 30-50 mg/dL, and >50 mg/dL was 0.91 (0.72-1.16), 1.05 (0.79-1.38), and 1.02 (0.83-1.26; vs. <15 mg/dL). However, among adults >50 years, lipoprotein(a) >50 mg/dL was associated with increased incident hypertension (1.62 [1.17-2.26]).

Exploratory qualitative study of firearm storage practices among surgeons in the USA: contexts and motivations.

BACKGROUND: A US survey of surgeons found that 32% store firearms unlocked and loaded. This study explored conditions and contexts impacting personal firearm storage methods among surgeons. METHODS: We conducted semi-structured interviews with English-speaking fellows of the American College of Surgeons who treated patients injured by firearms and who owned or lived in homes with firearms. Participants were recruited through email and subsequent snowball sampling from April 2022 to August 2022. All interviews were audio-recorded and transcribed verbatim. Thematic analysis was applied to transcripts to identify codes. A mixed deductive and inductive approach was used for data reduction and sorting. RESULTS: A total of 32 surgeons were interviewed; most were male and white. Dominant themes for firearm storage practices were based on (1) attitudes; (2) perceived norms; (3) personal agency; and (4) intention of firearm use. Personal agency often conflicted with attitudes and perceived norms for surgeons owning firearms for self-defence. CONCLUSIONS: Storage practices in this sample of firearm-owning surgeons were driven by intent for firearm use, coupled with attitudes, perceived norms and personal agency. Personal agency often conflicted with attitudes and perceived norms, especially for surgeons who owned their firearm for self-defence.

Trends in Black-White Differences of Antihypertensive Treatment in Individuals With and Without History of Stroke.

BACKGROUND: Recent hypertension guidelines for the general population have included race-specific recommendations for antihypertensives, whereas current stroke-specific recommendations for antihypertensives do not vary by race. The impact of these guidelines on antihypertensive regimen changes over time, and if this has varied by prevalent stroke status, is unclear. METHODS: The use of antihypertensive medications was studied cross-sectionally among self-identified Black and White participants, aged ≥45 years, with and without history of stroke, from the REGARDS study (Reasons for Geographic and Racial Differences in Stroke). Participants completed an in-home examination in 2003-2007 (visit 1) with/without an examination in 2013-2016 (visit 2). Stratified by prevalent stroke status, logistic regression mixed models examined associations between antihypertensive class use for visit 2 versus visit 1 and Black versus White individuals with an interaction adjusted for demographics, socioeconomic status, and vascular risk factors/vital signs. RESULTS: Of 17 244 stroke-free participants at visit 1, Black participants had greater adjusted odds of angiotensin-converting enzyme inhibitor usage than White participants (odds ratio [OR], 1.51 [95% CI, 1.30-1.77]). This difference was smaller in the 7476 stroke-free participants at visit 2 (OR, 1.16 [95% CI, 1.08-1.25]). In stroke-free participants at visit 1, Black participants had lower odds of calcium channel blocker (CCB) usage than White participants (OR, 0.47 [95% CI, 0.41-0.55]), but CCB usage did not differ significantly between Black and White stroke-free participants at visit 2 (OR, 1.02 [95% CI, 0.95-1.09]). Among 1437 stroke survivor participants at visit 1, Black participants had lower odds of CCB use than White participants (OR, 0.34 [95% CI, 0.26-0.45]). In 689 stroke survivor participants at visit 2, CCB use did not differ between Black and White participants (OR, 0.80 [95% CI, 0.61-1.06]). CONCLUSIONS: Racial differences in the use of guideline-recommended antihypertensives decreased between 2003-2007 and 2013-2016 in stroke-free individuals. In stroke survivors, racial differences in CCB usage narrowed over the time periods. These findings suggest there is still a mismatch between race-specific hypertension guidelines and recent clinical practice.

Patient and Hospital Characteristics Associated with Admission Among Patients With Minor Isolated Extremity Firearm Injuries: A Propensity-Matched Analysis.

Objective: To quantify the association between insurance and hospital admission following minor isolated extremity firearm injury. Background: The association between insurance and injury admission has not been examined. Methods: This was an observational retrospective cohort study of minor isolated extremity firearm injury captured in the Healthcare Cost and Utilization Project State Inpatient and Emergency Department Databases in 6 states (New York, Arkansas, Wisconsin, Massachusetts, Florida, and Maryland) from 2016 to 2017 among patients aged 16 years or older. The primary exposure was insurance. Admitted patients were propensity score matched to nonadmitted patients on age, extremity Abbreviated Injury Score, and Elixhauser Comorbidity Index with exact matching within hospital to adjust for selection bias. A general estimating equation logistic regression estimated the association between insurance and odds of admission in the matched cohort while controlling for sex, race, injury intent, injury type, hospital profit type, and trauma center designation with observations clustered by propensity score-matched pairs within hospital. Results: A total of 8151 patients presented to hospital with a minor isolated extremity firearm injury between 2016 and 2017 in 6 states. Patients were 88.0% male, 56.6% Black, and 71.7% aged 16 to 36 years old, and 22.1% were admitted. A total of 2090 patients were matched on propensity for admission. Privately insured matched patients had 1.70 higher adjusted odds of admission and 95% confidence interval of 1.30 to 2.22, compared with uninsured after adjusting for patient and hospital characteristics. Conclusions: Insurance was associated with hospital admission for minor isolated extremity firearm injury.

Impact of Poverty on Stroke Recurrence: A Population-Based Study.

BACKGROUND AND OBJECTIVES: Poverty is associated with greater stroke incidence. The relationship between poverty and stroke recurrence is less clear. METHODS: In this population-based study, incident strokes within the Greater Cincinnati/Northern Kentucky region were ascertained during the 2015 study period and followed up for recurrence until December 31, 2018. The primary exposure was neighborhood socioeconomic status (nSES), defined by the percentage of households below the federal poverty line in each census tract in 4 categories (≤5%, >5%-10%, >10%-25%, >25%). Poisson regression models provided recurrence rate estimates per 100,000 residents using population data from the 2015 5-year American Community Survey, adjusting for age, sex, and race. In a secondary analysis, Cox models allowed for the inclusion of vascular risk factors in the assessment of recurrence risk by nSES among those with incident stroke. RESULTS: Of 2,125 patients with incident stroke, 245 had a recurrent stroke during the study period. Poorer nSES was associated with increased stroke recurrence, with rates of 12.5, 17.5, 25.4, and 29.9 per 100,000 in census tracts with ≤5%, >5%-10%, >10%-25%, and >25% below the poverty line, respectively (p < 0.01). The relative risk (95% CI) for recurrent stroke among Black vs White individuals was 2.54 (1.91-3.37) before adjusting for nSES, and 2.00 (1.47-2.74) after adjusting for nSES, a 35.1% decrease. In the secondary analysis, poorer nSES (HR 1.74, 95% CI 1.10-2.76 for lowest vs highest category) and Black race (HR 1.31, 95% CI 1.01-1.70) were both independently associated with recurrence risk, though neither retained significance after full adjustment. Age, diabetes, and left ventricular hypertrophy were associated with increased recurrence risk in fully adjusted models. DISCUSSION: Residents of poorer neighborhoods had a dose-dependent increase in stroke recurrence risk, and neighborhood poverty accounted for approximately one-third of the excess risk among Black individuals. These results highlight the importance of poverty, race, and the intersection of the 2 as potent drivers of stroke recurrence.

'My doctor self and my human self': A qualitative study of physicians' presentation of self on social media.

INTRODUCTION: When using social media, physicians are encouraged and trained to maintain separate professional and personal identities. However, this separation is difficult and even undesirable, as the blurring of personal and professional online presence can influence patient trust. Thus, it is necessary to develop policies and educational resources that are more responsive to the blurring of personal and professional boundaries on social media. This study aims to provide an understanding of how physicians present themselves holistically online to inform such policies and resources. METHODS: Twenty-eight US-based physicians who use social media were interviewed. Participants were asked to describe how and why they use social media, specifically Twitter (rebranded as 'X' in 2023). Interviews were complemented by data from the participants' Twitter profiles. Data were analysed using reflexive thematic analysis guided by Goffman's dramaturgical model. This model uses the metaphor of a stage to characterise how individuals attempt to control the aspects of the identities-or faces-they display during social interactions. RESULTS: The participants presented seven faces, which included professionally focused faces (e.g. networker) and those more personal in nature (e.g. human). The participants crafted and maintained these faces through discursive choices in their tweets and profiles, which were motivated by their audience's perceptions. We identified overlaps and tensions at the intersections of these faces, which posed professional and personal challenges for participants. CONCLUSIONS: Physicians strategically emphasise their more professional or personal faces according to their objectives and motivations in different communicative situations, and tailor their language and content to better reach their target audiences. While tensions arise between these faces, physicians still prefer to project a rounded, integral image of themselves on social media. This suggests a need to reconsider social media policies and related educational initiatives to better align with the realities of these digital environments.

Appendicitis Hospitalization Care Costs Among Patients With Delayed Diagnosis of Appendicitis.

Importance: Delayed appendicitis diagnosis is associated with worse outcomes. Appendicitis hospital care costs associated with delayed diagnosis are unknown. Objective: To determine whether delayed appendicitis diagnosis was associated with increased appendicitis hospital care costs. Design, Setting, and Participants: This cohort study used data from patients receiving an appendectomy aged 18 to 64 years in 5 states (Florida, Maryland, Massachusetts, New York, Wisconsin) that were captured in the Healthcare Cost and Utilization Project State Inpatient and Emergency Department databases for the years 2016 and 2017 with no additional follow-up. Data were analyzed January through April 2023. Exposures: Delayed diagnosis was defined as a previous emergency department or inpatient hospital encounter with an abdominal diagnosis other than appendicitis, and no intervention 7 days prior to appendectomy encounter. Main Outcomes and Measures: The main outcome was appendicitis hospital care costs. This was calculated from aggregated charges of encounters 7 days prior to appendectomy, the appendectomy encounter, and 30 days postoperatively. Cost-to-charge ratios were applied to charges to obtain costs, which were then adjusted for wage index, inflation to 2022 US dollar, and with extreme outliers winsorized. A multivariable Poisson regression estimated appendicitis hospital care costs associated with a delayed diagnosis while controlling for age, sex, race and ethnicity, insurance status, care discontinuity, income quartile, hospital size, teaching status, medical school affiliation, percentage of Black and Hispanic patient discharges, core-based statistical area, and state. Results: There were 76 183 patients (38 939 female [51.1%]; 2192 Asian or Pacific Islander [2.9%], 14 132 Hispanic [18.5%], 8195 non-Hispanic Black [10.8%], 46 949 non-Hispanic White [61.6%]) underwent appendectomy, and 2045 (2.7%) had a delayed diagnosis. Delayed diagnosis patients had median (IQR) unadjusted cost of $11 099 ($6752-$17 740) compared with $9177 ($5575-$14 481) for nondelayed (P < .001). Patients with delayed diagnosis had 1.23 times (95% CI, 1.16-1.28 times) adjusted increased appendicitis hospital care costs. The mean marginal cost of delayed diagnosis was $2712 (95% CI, $2083-$3342). Even controlling for delayed diagnosis, non-Hispanic Black patients had 1.22 times (95% CI, 1.17-1.28 times) the adjusted increased appendicitis hospital care costs compared with non-Hispanic White patients. Conclusions and Relevance: In this cohort study, delayed diagnosis of appendicitis was associated with increased hospital care costs.

Association of Prior Stroke With Health Care Perceptions of Adequate Emergency Care in Women.

BACKGROUND: Women with a history of stroke represent a vulnerable patient population due to their extant disability, morbidity, and risk of recurrence. The association between prior stroke with patient experience and perception of emergency medical care is unknown. METHODS: We utilized data from the Health Care Experiences and Perception cross-sectional, online survey from the American Heart Association Research Goes Red Registry. Ordinal logistic regression models were performed to assess the association between a self-reported history of stroke in the prior 10 years and the perception of not receiving adequate care in an emergency department because of gender or race. Models were adjusted for age at the time of enrollment, race/ethnicity, myocardial infarction within 10 years, and current smoking status. RESULTS: A total of 3498 women participants met inclusion criteria: 89 participants with a history of stroke in the past 10 years (mean age, 49.4 years; 10.1% Black participants and 5.6% Hispanic participants) and 3409 participants without such history (mean age, 45.8 years; 7.8% Black participants and 7.0% Hispanic participants). In multivariate logistic regression models, stroke history was significantly associated with greater odds of answering "to a great extent" that "I will not receive adequate care in an emergency room based on my gender" (odds ratio, 3.23 [95% CI, 1.69-6.17]) and "…race/ethnicity" (odds ratio, 3.88 [95% CI, 1.45-10.39]). Similar results were seen for secondary outcomes. CONCLUSIONS: Women patients with a stroke history felt less likely to receive adequate emergency care based on gender and race/ethnicity. Whether these negative health perceptions are associated with delays in presentation for stroke or other time-sensitive conditions should be the focus of future studies, given that these populations are known to less frequently receive advanced therapies for stroke, in part due to delays in presentation.

Access, Outcomes, and Costs Associated with Surgery for Malignancy Among People Experiencing Homelessness.

BACKGROUND: Little is known about surgery for malignancy among people experiencing homelessness (PEH). Poor healthcare access may lead to delayed diagnosis and need for unplanned surgery. This study aimed to (1) characterize access to care among PEH, (2) evaluate postoperative outcomes, and (3) assess costs associated with surgery for malignancy among PEH. METHODS: This was a retrospective cohort study of patients in the Healthcare Cost and Utilization Project (HCUP) who underwent surgery in Florida, New York, or Massachusetts for gastrointestinal or lung cancer from 2016 to 2017. PEH were identified using HCUP's "Homeless" variable and ICD-10 code Z59. Multivariable regression models controlling patient and hospital variables evaluated associations between homelessness and postoperative morbidity, length of stay (LOS), 30-day readmission, and hospitalization costs. RESULTS: Of 67,034 patients at 566 hospitals, 98 (0.2%) were PEH. Most PEH (44.9%) underwent surgery for colorectal cancer. PEH more frequently underwent unplanned surgery than housed patients (65.3% vs 23.7%, odds ratio (OR) 5.17, 95% confidence interval (CI) 3.00-8.92) and less often were treated at cancer centers (66.0% vs 76.2%, p=0.02). Morbidity rates were similar between groups (20.4% vs 14.5%, p=0.10). However, PEH demonstrated higher odds of facility discharge (OR 5.89, 95% CI 3.50-9.78) and readmission (OR 1.81, 95% CI 1.07-3.05) as well as 67.7% longer adjusted LOS (95% CI 42.0-98.2%). Adjusted costs were 32.7% higher (95% CI 14.5-53.9%) among PEH. CONCLUSIONS: PEH demonstrated increased odds of unplanned surgery, longer LOS, and increased costs. These results underscore a need for improved access to oncologic care for PEH.

Door-in-Door-out Times for Interhospital Transfer of Patients With Stroke.

Importance: Treatments for time-sensitive acute stroke are not available at every hospital, often requiring interhospital transfer. Current guidelines recommend hospitals achieve a door-in-door-out time of no more than 120 minutes at the transferring emergency department (ED). Objective: To evaluate door-in-door-out times for acute stroke transfers in the American Heart Association Get With The Guidelines-Stroke registry and to identify patient and hospital factors associated with door-in-door-out times. Design, Setting, and Participants: US registry-based, retrospective study of patients with ischemic or hemorrhagic stroke from January 2019 through December 2021 who were transferred from the ED at registry-affiliated hospitals to other acute care hospitals. Exposure: Patient- and hospital-level characteristics. Main Outcomes and Measures: The primary outcome was the door-in-door-out time (time of transfer out minus time of arrival to the transferring ED) as a continuous variable and a categorical variable (≤120 minutes, >120 minutes). Generalized estimating equation (GEE) regression models were used to identify patient and hospital-level characteristics associated with door-in-door-out time overall and in subgroups of patients with hemorrhagic stroke, acute ischemic stroke eligible for endovascular therapy, and acute ischemic stroke transferred for reasons other than endovascular therapy. Results: Among 108 913 patients (mean [SD] age, 66.7 [15.2] years; 71.7% non-Hispanic White; 50.6% male) transferred from 1925 hospitals, 67 235 had acute ischemic stroke and 41 678 had hemorrhagic stroke. Overall, the median door-in-door-out time was 174 minutes (IQR, 116-276 minutes): 29 741 patients (27.3%) had a door-in-door-out time of 120 minutes or less. The factors significantly associated with longer median times were age 80 years or older (vs 18-59 years; 14.9 minutes, 95% CI, 12.3 to 17.5 minutes), female sex (5.2 minutes; 95% CI, 3.6 to 6.9 minutes), non-Hispanic Black vs non-Hispanic White (8.2 minutes, 95% CI, 5.7 to 10.8 minutes), and Hispanic ethnicity vs non-Hispanic White (5.4 minutes, 95% CI, 1.8 to 9.0 minutes). The following were significantly associated with shorter median door-in-door-out time: emergency medical services prenotification (-20.1 minutes; 95% CI, -22.1 to -18.1 minutes), National Institutes of Health Stroke Scale (NIHSS) score exceeding 12 vs a score of 0 to 1 (-66.7 minutes; 95% CI, -68.7 to -64.7 minutes), and patients with acute ischemic stroke eligible for endovascular therapy vs the hemorrhagic stroke subgroup (-16.8 minutes; 95% CI, -21.0 to -12.7 minutes). Among patients with acute ischemic stroke eligible for endovascular therapy, female sex, Black race, and Hispanic ethnicity were associated with a significantly higher door-in-door-out time, whereas emergency medical services prenotification, intravenous thrombolysis, and a higher NIHSS score were associated with significantly lower door-in-door-out times. Conclusions and Relevance: In this US registry-based study of interhospital transfer for acute stroke, the median door-in-door-out time was 174 minutes, which is longer than current recommendations for acute stroke transfer. Disparities and modifiable health system factors associated with longer door-in-door-out times are suitable targets for quality improvement initiatives.

Physician and Biomedical Scientist Harassment on Social Media During the COVID-19 Pandemic.

This survey study assesses the frequency and nature of harassment on social media experienced by physicians, biomedical scientists, and trainees during the COVID-19 pandemic.

Household income is associated with functional outcomes in a multi-institutional cohort of patients with ischemic stroke and COVID-19.

OBJECTIVES: The COVID-19 pandemic has heightened awareness of health disparities associated with socioeconomic status (SES) across the United States. We examined whether household income is associated with functional outcomes after stroke and COVID-19. MATERIALS AND METHODS: This was a multi-institutional, retrospective cohort study of consecutively hospitalized patients with SARS-CoV-2 and radiographically confirmed stroke presenting from March through November 2020 to any of five comprehensive stroke centers in metropolitan Chicago, Illinois, USA. Zip-code-derived household income was dichotomized at the Chicago median. Logistic regression was used to examine the relationship between household income and good functional outcome (modified Rankin Scale 0-3 at discharge, after ischemic stroke). RESULTS: Across five hospitals, 159 patients were included. Black patients comprised 48.1%, White patients 38.6%, and Hispanic patients 27.7%. Median household income was $46,938 [IQR: $32,460-63,219]. Ischemic stroke occurred in 115 (72.3%) patients (median NIHSS 7, IQR: 0.5-18.5) and hemorrhagic stroke in 37 (23.7%). When controlling for age, sex, severe COVID-19, and NIHSS, patients with ischemic stroke and household income above the Chicago median were more likely to have a good functional outcome at discharge (OR 7.53, 95% CI 1.61 - 45.73; P=0.016). Race/ethnicity were not included in final adjusted models given collinearity with income. CONCLUSIONS: In this multi-institutional study of hospitalized patients with stroke, those residing in higher SES zip codes were more likely to have better functional outcomes, despite controlling for stroke severity and COVID-19 severity. This suggests that area-based SES factors may play a role in outcomes from stroke and COVID-19.
