RESUMEN

Patients with advanced cancer generate 4 million visits annually to emergency departments (EDs) and other dedicated, high-acuity oncology urgent care centers. Because of both the increasing complexity of systemic treatments overall and the higher rates of active therapy in the geriatric population, many patients experiencing acute decompensations are frail and acutely ill. This article comprehensively reviews the spectrum of oncologic emergencies and urgencies typically encountered in acute care settings. Presentation, underlying etiology, and up-to-date clinical pathways are discussed. Criteria for either a safe discharge to home or a transition of care to the inpatient oncology hospitalist team are emphasized. This review extends beyond familiar conditions such as febrile neutropenia, hypercalcemia, tumor lysis syndrome, malignant spinal cord compression, mechanical bowel obstruction, and breakthrough pain crises to include a broader spectrum of topics encompassing the syndrome of inappropriate antidiuretic hormone secretion, venous thromboembolism and malignant effusions, as well as chemotherapy-induced mucositis, cardiomyopathy, nausea, vomiting, and diarrhea. Emergent and urgent complications associated with targeted therapeutics, including small molecules, naked and drug-conjugated monoclonal antibodies, as well as immune checkpoint inhibitors and chimeric antigen receptor T-cells, are summarized. Finally, strategies for facilitating same-day direct admission to hospice from the ED are discussed. This article not only can serve as a point-of-care reference for the ED physician but also can assist outpatient oncologists as well as inpatient hospitalists in coordinating care around the ED visit.

RESUMEN

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.

RESUMEN

Acute dizziness and vertigo are common emergency department presentations (≈4% of annual visits) and sometimes, a life-threatening diagnosis like stroke is missed. Recent literature reviews the challenges in evaluation of these symptoms and offers guidelines for diagnostic approaches. Strong evidence indicates that when well-trained providers perform a high-quality bedside neurovestibular examination, accurate diagnosis of peripheral vestibular disorders and stroke increases. However, it is less clear who can and should be performing these assessments on a routine basis. This article offers a focused debate for and against routine specialty consultation for patients with acute dizziness or vertigo in the emergency department as well as a potential path forward utilizing new portable technologies to quantify eye movements.

RESUMEN

BACKGROUND: Transfemoral access is predominantly used for mechanical thrombectomy in patients with stroke with a large vessel occlusion. Following the interventional cardiology guidelines, routine transradial access has been proposed as an alternative, although its safety and efficacy remain controversial. We aim to explore the noninferiority of radial access in terms of final recanalization. METHODS: The study was an investigator-initiated, single-center, evaluator-blinded, noninferiority randomized clinical trial. Patients with stroke undergoing mechanical thrombectomy, with a patent femoral artery and a radial artery diameter ≥2.5 mm, were randomly assigned (1:1) to either transradial (60 patients) or transfemoral access (60 patients). The primary binary outcome was the successful recanalization (expanded Treatment in Cerebral Ischemia score, 2b-3) assigned by blinded evaluators. We established a noninferiority margin of -13.2%, considering an acceptable reduction of 15% in the expected recanalization rates. RESULTS: From September 2021 to July 2023, 120 patients were randomly assigned and 116 (58 transradial access and 58 transfemoral access) with confirmed intracranial occlusion on the initial angiogram were included in the intention-to-treat analysis. Successful recanalization was achieved in 51 (87.9%) patients assigned to transfemoral access and in 56/58 (96.6%) patients assigned to transradial (adjusted 1 side risk difference [RD], -5.0% [95% CI, -6.61% to +13.1%]) showing noninferiority of transradial access. Median time from angiosuite arrival to first pass (femoral, 30 [interquartile range, 25-37] minutes versus radial: 41 [interquartile range, 33-62] minutes; P<0.001) and from angiosuite arrival to recanalization (femoral: 42 (IQR, 28-74) versus radial: 59.5 (IQR, 44-81) minutes; P<0.050) were longer in the transradial access group. Both groups presented 1 severe access complication and there was no difference in the rate of access conversion: transradial 7 (12.1%) versus transfemoral 5 (8.6%) (P=0.751). CONCLUSIONS: Among patients who underwent mechanical thrombectomy, transradial access was noninferior to transfemoral access in terms of final recanalization. Procedural delays may favor transfemoral access as the default first-line approach. REGISTRATION: URL: https://www.clinicaltrials.gov; Unique identifier: NCT05225636.

RESUMEN

Among 100 propensity score-matched emergency department patients receiving ≤14 days doxycycline versus cephalexin monotherapy for outpatient treatment of nonpurulent (presumed streptococcal) skin and soft tissue infection, a low rate of 14-day clinical failure was observed [6% each group; odds ratio (OR), 1.34 (0.21-8.69); P = 0.745], defined as hospital admission, i.v. antibiotic therapy, or change in oral antibiotic. Doxycycline may represent a reasonable therapeutic alternative for this indication in regions with low tetracycline resistance.

RESUMEN

Despite advances in clinical decision support, the diagnosis, prognostic risk stratification, treatment and disposition of emergency department patients with pulmonary embolism remain challenging. The use of diagnostic risk stratification tools and D-dimer can decrease unnecessary exposure to radiation and intravenous contrast; however, D-dimer is elevated in many conditions including normal pregnancy, so imaging is often indicated. Once diagnosed, prognostic risk stratification tools can inform treatment decisions across the risk spectrum, including identifying low-risk patients with pulmonary embolism who can safely be treated at home. For patients requiring hospitalization, alternatives to unfractionated heparin can improve time to therapeutic anticoagulation and reduce treatment-related bleeding risk.

RESUMEN

Significant inconsistencies in respiratory care provision for Duchenne muscular dystrophy (DMD) are reported across different specialist neuromuscular centres in the UK. The absence of robust clinical evidence and expert consensus is a barrier to the implementation of care recommendations in public healthcare systems as is the need to increase awareness of key aspects of care for those living with DMD. Here, we provide evidenced-based and/or consensus-based best practice for the respiratory care of children and adults living with DMD in the UK, both as part of routine care and in an emergency. METHODOLOGY: Initiated by an expert working group of UK-based respiratory physicians (including British Thoracic Society (BTS) representatives), neuromuscular clinicians, physiotherapist and patient representatives, draft guidelines were created based on published evidence, current practice and expert opinion. After wider consultation with UK respiratory teams and neuromuscular services, consensus was achieved on these best practice recommendations for respiratory care in DMD. RESULT: The resulting recommendations are presented in the form of a flow chart for assessment and monitoring, with additional guidance and a separate chart setting out key considerations for emergency management. The recommendations have been endorsed by the BTS. CONCLUSIONS: These guidelines provide practical, reasoned recommendations for all those managing day-to-day and acute respiratory care in children and adults with DMD. The hope is that this will support patients and healthcare professionals in accessing high standards of care across the UK.

RESUMEN

OBJECTIVES: To assess pediatric critical care transport (CCT) teams' performance in a simulated environment and to explore the impact of team and center characteristics on performance. STUDY DESIGN: This observational, multicenter, simulation-based study enlisted a national cohort of pediatric transport centers. Teams participated in 3 scenarios: nonaccidental abusive head injury, sepsis, and cardiac arrest. The primary outcome was teams' simulation performance score. Secondary outcomes were associations between performance, center and team characteristics. RESULTS: We recruited 78 transport teams with 196 members from 12 CCT centers. Scores on performance measures that were developed were 89% (IQR 78-100) for nonaccidental abusive head injury, 63.3% (IQR 45.5-81.8) for sepsis, and 86.6% (IQR 66.6-93.3) for cardiac arrest. In multivariable analysis, overall performance was higher for teams including a respiratory therapist (0.5 points [95% CI: 0.13, 0.86]) or paramedic (0.49 points [95% CI: 0.1, 0.88]) and dedicated pediatric teams (0.37 points [95% 0.06, 0.68]). Each year increase in program age was associated with an increase of 0.04 points (95% CI: 0.02, 0.06). CONCLUSIONS: Dedicated pediatric teams, inclusion of respiratory therapists and paramedics, and center age were associated with higher simulation scores for pediatric CCT teams. These insights can guide efforts to enhance the quality of care for children during interfacility transports.

RESUMEN

OBJECTIVE: To determine factors associated with magnetic resonance imaging (MRI) and noninvasive diagnostic angiography among children presenting to the emergency department (ED) with acute ischemic stroke. STUDY DESIGN: We performed a cross-sectional study using data from >50 US children's hospitals. We included children 29 days through 17 years old hospitalized from the ED with an International Classification of Diseases, Tenth Revision, Clinical Modification, diagnosis code for acute ischemic stroke between October 1, 2015, and November 30, 2022. We excluded children with a principal diagnosis code of trauma/external injury, without neuroimaging on day of presentation, and into-ED transfers. Our outcomes were defined as acquisition of MRI (vs computed tomography only) and angiography (vs no angiography) on day of presentation. We performed generalized linear mixed modeling with hospital as a random effect to determine the association of demographics, known comorbidities, and treatment factors with each outcome. RESULTS: We included 1601 children. In multivariable analysis, younger age, mechanical ventilation, and Black race were associated with lower odds of MRI acquisition, whereas history of moyamoya disease and sickle cell disease were associated with greater odds. Younger age, mechanical ventilation, Hispanic ethnicity, Black race, other races, history of metabolic disease, and history of seizures were associated with lower odds of angiography. CONCLUSIONS: Younger and non-White children experienced lower odds of MRI and angiography, which may be driven by health system limitations or provider implicit biases or both. Our results expose risk factors for underdiagnosis of ischemic stroke and provide opportunities to tailor institutional pathways reflective of underlying pathophysiology.

RESUMEN

The emergency department (ED) has increasingly become an important public health partner in non-targeted hepatitis C virus (HCV) testing and referral to care efforts. HCV has traditionally been an infection associated with the Baby Boomer generation; however, recent exacerbation of the opioid epidemic has resulted in a growing number of younger cohorts, namely Millennials, also impacted by HCV. Examination of this age-related demographic shift, including subsequent linkage success and linkage barriers, from the perspective of an ED-based testing and linkage programme may have implications for future population and health systems interventions. A retrospective descriptive chart review was performed, inclusive of data from August 2015 through December 2020. We compared the quantity of positive HCV screening antibody (Ab) and confirmatory (RNA) tests and further considered linkage rates and correlative demographics (e.g. gender, race). Patient barriers to HCV care linkage (e.g. substance misuse, lack of health insurance, homelessness) were also evaluated. The data set was disaggregated by birth cohort to include Silent Generation (SG) (1928-45), Baby Boomer (BB) (1946-64), Generation X (Gen X) (1965-80), Millennial (1981-96) and Generation Z (1997-2012). Descriptive statistics and chi-square analysis were performed. Overall, 83,817 patients were tested for HCV (50.6% of eligible); 6187 (7.4%) were HCV Ab positive, and 2665 were HCV RNA positive (3.2%). RNA-positive individuals were more likely to be white (70.4%) and male (67.7%); generational distribution was similar (BB 33.3%, Gen X 32.0% and Millennials 32.7%). Amongst Ab-positive patients, white (45.5%), male (47.2%) and Millennial (49.7%) individuals were most likely to be RNA-positive. Overall, 28.1% of the RNA-positive cohort successfully linked to care; linkage to care rates were significantly higher in older generations (38.1% in BB vs. 17.8% in Millennials) (p < .00001). Over 90% were identified as having at least one linkage to care barrier. Younger generations (Gen X and Millennials) were disproportionately impacted by linkage barriers, including incarceration, lack of health insurance, history of mental health and substance use disorders, as well as history of or active injection drug use (IDU) (p < .00001). Older generations (SG and BB) were more likely to be impacted by competing medical comorbidities (p < .00001). The ED population represents a particularly vulnerable, at-risk cohort with a high prevalence of HCV and linkage to care barriers. While past HCV-specific recommendations and interventions have focused on Baby Boomers, this data suggests that younger generations, including Gen X and Millennials, are increasingly affected by HCV and face disparate social risk and social need factors which impede definitive care linkage and treatment.

RESUMEN

Intimate partner violence is a serious, but underappreciated, issue that predominantly affects women and often results in concussion (i.e., mild traumatic brain injury). However, concussion in intimate partner violence is unique because it often involves a concomitant strangulation which may exacerbate or alter the physiology and clinical presentation of the brain injury. Therefore, here we conducted human and rodent studies to provide insight into knowledge gaps related to the detection, pathophysiology, and functional consequences of intimate partner violence-related brain injury. We conducted the first study to analyze blood biomarkers and symptoms of brain injury in intimate partner violence patients presenting to an emergency department within 72 h of concussion. Intimate partner violence concussion patients, some of whom had also experienced a concomitant strangulation, had elevated serum neurofilament light and worse brain injury symptoms compared to healthy control, orthopedic trauma, and non-intimate partner violence concussion groups. We also developed the first rat model of non-fatal strangulation and examined the consequences of strangulation and concussion in isolation and in combination on pathophysiology, blood biomarkers, and behavior at 2 h and 1wk post-injury. Rats exposed to combined strangulation and concussion had exacerbated motor and cognitive deficits, neuroinflammation, and serum glial fibrillary acidic protein levels compared with either injury in isolation. Taken together, these rodent findings demonstrate that a concomitant strangulation modifies and exacerbates concussion pathophysiology, biomarkers, and functional consequences. Overall, these findings provide novel insights into intimate partner violence-related brain injury and provides a foundation for future translational studies.

RESUMEN

BACKGROUND AND OBJECTIVES: The appropriate use of blood components is essential for ethical use of a precious, donated product. The aim of this study was to report in-hospital red blood cell (RBC) transfusion after pre-hospital transfusion by helicopter emergency medical service paramedics. A secondary aim was to assess the potential for venous blood lactate to predict ongoing transfusion. MATERIALS AND METHODS: All patients who received RBC in air ambulance were transported to a single adult major trauma centre, had venous blood lactate measured on arrival and did not die before ability to transfuse RBC were included. The association of venous blood lactate with ongoing RBC transfusion was assessed using multi-variable logistic regression analysis and reported using adjusted odds ratios (aOR). The discriminative ability of venous blood lactate was assessed using area under receiver operating characteristics curve (AUROC). RESULTS: From 1 January 2016 to 15 May 2019, there were 165 eligible patients, and 128 patients were included. In-hospital transfusion occurred in 97 (75.8%) of patients. Blood lactate was associated with ongoing RBC transfusion (aOR: 2.00; 95% confidence interval [CI]: 1.36-2.94). Blood lactate provided acceptable discriminative ability for ongoing transfusion (AUROC: 0.78; 95% CI: 0.70-0.86). CONCLUSIONS: After excluding patients with early deaths, a quarter of those who had prehospital RBC transfusion had no further transfusion in hospital. Venous blood lactate appears to provide value in identifying such patients. Lactate levels after pre-hospital transfusion could be used as a biomarker for transfusion requirement after trauma.

RESUMEN

AIMS: The aim of this study is to describe the disposition of tranexamic acid (TXA) in adult trauma patients and derive a dosing regimen that optimizes exposure based on a predefined exposure target. METHODS: We performed a population pharmacokinetic (popPK) analysis of participants enrolled in the Tranexamic Acid Mechanisms and Pharmacokinetics in Traumatic Injury (TAMPITI) trial (≥18 years with traumatic injury, given ≥1 blood product and/or requiring immediate transfer to the operating room) who were randomized to a single dose of either 2 or 4 g of TXA ≤2 h from time of injury. PopPK analysis was conducted using nonlinear mixed-effects modelling (NONMEM). Simulations were then performed using the final model to generate estimated plasma TXA concentrations in 1000 simulated participants. Dosing schemes were evaluated to determine maintenance of TXA plasma concentrations >10 mg/L for ≥8 h after administration of the initial dose. RESULTS: TXA PK was best described by a two-compartment model with proportional residual error and allometric scaling on all parameters. Platelet count, skeletal muscle oxygen saturation measured by near-infrared spectroscopy and interleukin-8 concentration were significant covariates on TXA clearance. Based on simulations, a 2 g IV bolus dose, repeated 3 h later, best achieved the target exposure. CONCLUSIONS: According to simulations from a popPK model of TXA, a 2 g IV bolus with a repeated dose 3 h later would be most likely to maintain concentrations >10 mg/L for 8 h in >95% of adult trauma patients and should be considered for patients with ongoing haemorrhage.

RESUMEN

INTRODUCTION: The outpatient parenteral antibiotic therapy (OPAT) program of Vancouver General Hospital (VGH) was supervised by emergency physicians (EPs) until 2017 when infectious disease (ID) physicians began assisting in management. We designed a retrospective study to determine whether ID involvement led to improved outcomes. METHODS: This study analyzes the impact of ID involvement by comparing the mean days patients spent on OPAT with ID involvement versus EPs alone through a retrospective chart review. Secondary research objectives were to compare patient care decisions, e.g., antibiotic choice, tests ordered, and final diagnosis. RESULTS: There was no difference between the mean number of days on OPAT between physician types. Compared to historic patterns, patients seen in OPAT after increased ID consultation spent an average of 0.5 fewer days in the program. However, when grouped by the first day of ID assessment, the average total days in OPAT was closely aligned with the day of first ID assessment, implying that ID frequently discharged patients close to initial assessment. Patients seen by ID were less likely to return within one month of discharge compared to those not seen by ID. Secondary findings include ID physicians prescribing a greater range of antibiotics, providing more varied final diagnoses, prescribing antibiotics less frequently, as well as ordering more cultures, diagnostic imaging and specialist consults. DISCUSSION: The findings of this study support the hypothesis that ID involvement in OPAT programs leads to changes in care that may have beneficial outcomes for patients and the healthcare system.

RESUMEN

BACKGROUND: Although the clinical impact of emergency medicine clinical pharmacists (EMCPs) on patient care outcomes is well documented, their educational impact on resident physicians' training is not. OBJECTIVE: To further highlight the utility of EMCPs, this study evaluated emergency medicine (EM) resident physicians' perceptions of EMCPs' involvement in their training. METHODS: A voluntary, anonymous web-based survey was sent by email to all 44 EM resident physicians in July 2022. The survey included multiple choice, 5-point Likert scale, and free response questions derived from Accreditation Council for Graduate Medical Education pharmacotherapy competency-based milestones. RESULTS: Thirty-six of the 44 (82%) residents completed the survey and all 10 PGY-4 class residents completed the survey. Nearly half of the respondents (44.4%) reported they consulted/interacted with the EMCPs 3 to 5 times per week and this number increased with the level of training. Respondents most often consulted the EMCPs to obtain medication indications, antibiotic dosing, pediatric dosing, and contraindications. Overall, respondents primarily reported strongly agree to all survey questions. Nearly all respondents strongly agreed the EMCPs are an important part of the patient care team and provide education that is different from what a supervising physician provides. All respondents who completed the pharmacy elective strongly agreed the elective was valuable and strongly recommended other residents to complete it. CONCLUSION AND RELEVANCE: Respondents reported EMCPs are an important part of the patient care team, play a significant role in their training, and provide education that is different from what a supervising physician provides. Our findings encourage other institutions to leverage physicians' views of EMCPs to expand their service line.

RESUMEN

BACKGROUND: Sugammadex rapidly reverses the nondepolarizing neuromuscular blocking agents (NMBAs) rocuronium and vecuronium. The role of sugammadex is not well-defined outside of the postoperative setting. OBJECTIVE: This study aims to describe sugammadex use outside the postoperative setting for the reversal of nondepolarizing NMBAs. METHODS: This was a single-center, retrospective cohort study conducted in patients who received sugammadex outside of the postoperative setting at an academic medical center between June 2016 and November 2022. The primary outcome was the effect of sugammadex use for rocuronium reversal, defined as any increase in train-of-four (TOF) after sugammadex administration and/or progress note documentation if TOF was unavailable. Secondary outcomes included adverse events and documentation of contraceptive counseling in patients taking hormonal contraceptives with child-bearing ability. RESULTS: A total of 14 383 patients received sugammadex during the study period. Of those patients, 39 (0.3%) were outside of the postoperative setting for the reversal of rocuronium and included in the study. Twenty-nine (74%) patients had an increase in TOF after sugammadex administration and/or progress note documentation if TOF was unavailable. Ten (26%) patients lacked documentation regarding the effect of sugammadex. No adverse reactions were reported. Three (8%) patients included in the study were of child-bearing ability, and 1 of the 3 patients was counseled on using an alternative method of contraception following sugammadex administration. CONCLUSION AND RELEVANCE: There is a paucity of literature for the use of sugammadex outside of the postoperative setting. This study found that while the use of sugammadex was rare, overall, it was safe and well-tolerated.

RESUMEN

INTRODUCTION: Vulnerably housed individuals access emergency departments (EDs) more frequently than the general population. Despite Canada's universal public health care system, vulnerably housed persons face structural barriers to care and experience discrimination from healthcare providers. This study examines how vulnerably housed persons perceive their experience of care in the ED and Urgent Care Center (UCC) in Kingston, Ontario and aims to develop strategies for improving care for this group. METHODS: As part of a larger mixed-methods study, narratives were collected from participants attending the ED/UCC as well as community-based partner organizations, asking them to describe an experience of a recent ED visit (< 24 months). Participants could identify as members of up to three equity-deserving groups (EDGs) (for example homeless, part of an ethnic minority, having a disability, experiencing mental health issues). Coding and thematic analysis were completed for the experiences of participants who identified as being vulnerably housed (n = 171). Results were presented back to individuals with lived experience and service providers working with clients with unstable housing. RESULTS: Participants reported judgement related to a past or presumed history of mental health or substance use and based on physical appearance. They also often felt unheard and that they were treated as less than human by healthcare providers. Lack of effective communication about the ED process, wait times, diagnosis, and treatment led to negative care experiences. Participants reported positive experiences when their autonomy in care-decision making was respected. Furthermore, having a patient-centered approach to care and addressing specific patient needs, identities and priorities led to positive care experiences. CONCLUSIONS: The ED care experiences of vulnerably housed persons may be improved through healthcare provider training related to trauma-informed and patient-centered care and communication strategies in the ED. Another potential strategy to improve care is to have advocates accompany vulnerably housed persons to the ED. Finally, improving access to primary care may lead to reduced ED visits and better longitudinal care for vulnerably housed persons.

RESUMEN

PURPOSE OF REVIEW: Mobile stroke units (MSU) have established a new, evidence-based treatment in prehospital stroke care, endorsed by current international guidelines and can facilitate pre-hospital research efforts. In addition, other novel pre-hospital modalities beyond the MSU are emerging. In this review, we will summarize existing evidence and outline future trajectories of prehospital stroke care & research on and off MSUs. RECENT FINDINGS: The proof of MSUs' positive effect on patient outcomes is leading to their increased adoption in emergency medical services of many countries. Nevertheless, prehospital stroke care worldwide largely consists of regular ambulances. Advancements in portable technology for detecting neurocardiovascular diseases, telemedicine, AI and large-scale ultra-early biobanking have the potential to transform prehospital stroke care also beyond the MSU concept. The increasing implementation of telemedicine in emergency medical services is demonstrating beneficial effects in the pre-hospital setting. In synergy with telemedicine the exponential growth of AI-technology is already changing and will likely further transform pre-hospital stroke care in the future. Other promising areas include the development and validation of miniaturized portable devices for the pre-hospital detection of acute stroke. MSUs are enabling large-scale screening for ultra-early blood-based biomarkers, facilitating the differentiation between ischemia, hemorrhage, and stroke mimics. The development of suitable point-of-care tests for such biomarkers holds the potential to advance pre-hospital stroke care outside the MSU-concept. A multimodal approach of AI-supported telemedicine, portable devices and blood-based biomarkers appears to be an increasingly realistic scenario for improving prehospital stroke care in regular ambulances in the future.

RESUMEN

Numerous states implemented laws to protect emergency patients from surprise out-of-network medical bills. We investigated the effects of the state laws on emergency clinician reimbursements, charges, network participation, and potential surprise billing episodes. We did not find consistent evidence of effects on prices or charges. However, the state laws resulted in increased network participation and a reduction in potential surprise billing episodes. Our results suggest that the federal No Surprises Act, which is similar to many of the state laws, is unlikely to lead to price increases, but may benefit patients through increased provider network participation and alignment.
