RESUMEN
BACKGROUND AND AIMS: Home treatment is considered safe in acute pulmonary embolism (PE) patients selected by a validated triage tool (e.g. simplified PE severity index score or Hestia rule), but there is uncertainty regarding the applicability in underrepresented subgroups. The aim was to evaluate the safety of home treatment by performing an individual patient-level data meta-analysis. METHODS: Ten prospective cohort studies or randomized controlled trials were identified in a systematic search, totalling 2694 PE patients treated at home (discharged within 24â h) and identified by a predefined triage tool. The 14- and 30-day incidences of all-cause mortality and adverse events (combined endpoint of recurrent venous thromboembolism, major bleeding, and/or all-cause mortality) were evaluated. The relative risk (RR) for 14- and 30-day mortalities and adverse events is calculated in subgroups using a random effects model. RESULTS: The 14- and 30-day mortalities were 0.11% [95% confidence interval (CI) 0.0-0.24, I2 = 0) and 0.30% (95% CI 0.09-0.51, I2 = 0). The 14- and 30-day incidences of adverse events were 0.56% (95% CI 0.28-0.84, I2 = 0) and 1.2% (95% CI 0.79-1.6, I2 = 0). Cancer was associated with increased 30-day mortality [RR 4.9; 95% prediction interval (PI) 2.7-9.1; I2 = 0]. Pre-existing cardiopulmonary disease, abnormal troponin, and abnormal (N-terminal pro-)B-type natriuretic peptide [(NT-pro)BNP] at presentation were associated with an increased incidence of 14-day adverse events [RR 3.5 (95% PI 1.5-7.9, I2 = 0), 2.5 (95% PI 1.3-4.9, I2 = 0), and 3.9 (95% PI 1.6-9.8, I2 = 0), respectively], but not mortality. At 30 days, cancer, abnormal troponin, and abnormal (NT-pro)BNP were associated with an increased incidence of adverse events [RR 2.7 (95% PI 1.4-5.2, I2 = 0), 2.9 (95% PI 1.5-5.7, I2 = 0), and 3.3 (95% PI 1.6-7.1, I2 = 0), respectively]. CONCLUSIONS: The incidence of adverse events in home-treated PE patients, selected by a validated triage tool, was very low. Patients with cancer had a three- to five-fold higher incidence of adverse events and death. Patients with increased troponin or (NT-pro)BNP had a three-fold higher risk of adverse events, driven by recurrent venous thromboembolism and bleeding.

BACKGROUND: Guidelines emphasize rapid antibiotic treatment for sepsis, but infection presence is often uncertain at initial presentation. We investigated the incidence and drivers of false-positive presumptive infection diagnosis among emergency department (ED) patients meeting Sepsis-3 criteria. METHODS: For a retrospective cohort of patients hospitalized after meeting Sepsis-3 criteria (acute organ failure and suspected infection including blood cultures drawn and intravenous antimicrobials administered) in 1 of 4 EDs from 2013 to 2017, trained reviewers first identified the ED-diagnosed source of infection and adjudicated the presence and source of infection on final assessment. Reviewers subsequently adjudicated final infection probability for a randomly selected 10% subset of subjects. Risk factors for false-positive infection diagnosis and its association with 30-day mortality were evaluated using multivariable regression. RESULTS: Of 8267 patients meeting Sepsis-3 criteria in the ED, 699 (8.5%) did not have an infection on final adjudication and 1488 (18.0%) patients with confirmed infections had a different source of infection diagnosed in the ED versus final adjudication (ie, initial/final source diagnosis discordance). Among the subset of patients whose final infection probability was adjudicated (n = 812), 79 (9.7%) had only "possible" infection and 77 (9.5%) were not infected. Factors associated with false-positive infection diagnosis included hypothermia, altered mental status, comorbidity burden, and an "unknown infection source" diagnosis in the ED (odds ratio: 6.39; 95% confidence interval: 5.14-7.94). False-positive infection diagnosis was not associated with 30-day mortality. CONCLUSIONS: In this large multihospital study, <20% of ED patients meeting Sepsis-3 criteria had no infection or only possible infection on retrospective adjudication.

BACKGROUND: Assessment for risks associated with acute stable COVID-19 is important to optimize clinical trial enrollment and target patients for scarce therapeutics. To assess whether healthcare system engagement location is an independent predictor of outcomes we performed a secondary analysis of the ACTIV-4B Outpatient Thrombosis Prevention trial. METHODS: A secondary analysis of the ACTIV-4B trial that was conducted at 52 US sites between September 2020 and August 2021. Participants were enrolled through acute unscheduled episodic care (AUEC) enrollment location (emergency department, or urgent care clinic visit) compared to minimal contact (MC) enrollment (electronic contact from test center lists of positive patients).We report the primary composite outcome of cardiopulmonary hospitalizations, symptomatic venous thromboembolism, myocardial infarction, stroke, transient ischemic attack, systemic arterial thromboembolism, or death among stable outpatients stratified by enrollment setting, AUEC versus MC. A propensity score for AUEC enrollment was created, and Cox proportional hazards regression with inverse probability weighting (IPW) was used to compare the primary outcome by enrollment location. RESULTS: Among the 657 ACTIV-4B patients randomized, 533 (81.1%) with known enrollment setting data were included in this analysis, 227 from AUEC settings and 306 from MC settings. In a multivariate logistic regression model, time from COVID test, age, Black race, Hispanic ethnicity, and body mass index were associated with AUEC enrollment. Irrespective of trial treatment allocation, patients enrolled at an AUEC setting were 10-times more likely to suffer from the adjudicated primary outcome, 7.9% vs. 0.7%; p < 0.001, compared with patients enrolled at a MC setting. Upon Cox regression analysis adjustment patients enrolled at an AUEC setting remained at significant risk of the primary composite outcome, HR 3.40 (95% CI 1.46, 7.94). CONCLUSIONS: Patients with clinically stable COVID-19 presenting to an AUEC enrollment setting represent a population at increased risk of arterial and venous thrombosis complications, hospitalization for cardiopulmonary events, or death, when adjusted for other risk factors, compared with patients enrolled at a MC setting. Future outpatient therapeutic trials and clinical therapeutic delivery programs of clinically stable COVID-19 patients may focus on inclusion of higher-risk patient populations from AUEC engagement locations.

BACKGROUND: Unlike well-established diseases that base clinical care on randomized trials, past experiences, and training, prognosis in COVID19 relies on a weaker foundation. Knowledge from other respiratory failure diseases may inform clinical decisions in this novel disease. The objective was to predict 48-hour invasive mechanical ventilation (IMV) within 48 h in patients hospitalized with COVID-19 using COVID-like diseases (CLD). METHODS: This retrospective multicenter study trained machine learning (ML) models on patients hospitalized with CLD to predict IMV within 48 h in COVID-19 patients. CLD patients were identified using diagnosis codes for bacterial pneumonia, viral pneumonia, influenza, unspecified pneumonia and acute respiratory distress syndrome (ARDS), 2008-2019. A total of 16 cohorts were constructed, including any combinations of the four diseases plus an exploratory ARDS cohort, to determine the most appropriate cohort to use. Candidate predictors included demographic and clinical parameters that were previously associated with poor COVID-19 outcomes. Model development included the implementation of logistic regression and three ensemble tree-based algorithms: decision tree, AdaBoost, and XGBoost. Models were validated in hospitalized COVID-19 patients at two healthcare systems, March 2020-July 2020. ML models were trained on CLD patients at Stanford Hospital Alliance (SHA). Models were validated on hospitalized COVID-19 patients at both SHA and Intermountain Healthcare. RESULTS: CLD training data were obtained from SHA (n = 14,030), and validation data included 444 adult COVID-19 hospitalized patients from SHA (n = 185) and Intermountain (n = 259). XGBoost was the top-performing ML model, and among the 16 CLD training cohorts, the best model achieved an area under curve (AUC) of 0.883 in the validation set. In COVID-19 patients, the prediction models exhibited moderate discrimination performance, with the best models achieving an AUC of 0.77 at SHA and 0.65 at Intermountain. The model trained on all pneumonia and influenza cohorts had the best overall performance (SHA: positive predictive value (PPV) 0.29, negative predictive value (NPV) 0.97, positive likelihood ratio (PLR) 10.7; Intermountain: PPV, 0.23, NPV 0.97, PLR 10.3). We identified important factors associated with IMV that are not traditionally considered for respiratory diseases. CONCLUSIONS: The performance of prediction models derived from CLD for 48-hour IMV in patients hospitalized with COVID-19 demonstrate high specificity and can be used as a triage tool at point of care. Novel predictors of IMV identified in COVID-19 are often overlooked in clinical practice. Lessons learned from our approach may assist other research institutes seeking to build artificial intelligence technologies for novel or rare diseases with limited data for training and validation.

OBJECTIVE: Evaluate the cost-effectiveness and difference in length-of-stay when patients in the ED diagnosed with low-risk pulmonary embolism (PE) are managed with early discharge or observation. METHODS: Single cohort prospective management study from January 2013 to October 2016 of patients with PE diagnosed in the ED and evaluated for a primary composite endpoint of mortality, recurrent venous thromboembolism, and/or major bleeding event at 90 days. Low-risk patients had a PE Severity Index score < 86, no evidence of proximal deep vein thrombosis on venous compression ultrasonography of both lower extremities, and no evidence of right heart strain on echocardiography. Patients were managed either in the ED or in the hospital on observation status. Primary outcomes were total length of stay, total encounter costs, and 30-day costs. RESULTS: 213 patients were enrolled. 13 were excluded per the study protocol. Of the remaining 200, 122 were managed with emergency department observation (EDO) and 78 with hospital observation (HO). One patient managed with EDO met the composite outcome due to a major bleeding event on day 61. The mean length of stay for EDO was 793.4 min (SD -169.7, 95% CI:762-823) and for HO was 1170 (SD -211.4, 95% CI:1122-1218) with a difference of 376.8 (95% CI: 430-323, p < 0.0001). Total encounter mean costs for EDO were $1982.95 and $2759.59 for HO, with a difference of $776.64 (95% CI: 972-480, p > 0.0001). 30-day total mean costs for EDO were $2864.14 and $3441.52 for HO, with a difference of $577.38 (95% CI: -1372-217, p = 0.15). CONCLUSIONS: Patients with low-risk PE managed with ED-based observation have a shorter length of stay and lower total encounter costs than patients managed with Hospital-based observation.

Importance: Acutely ill inpatients with COVID-19 typically receive antithrombotic therapy, although the risks and benefits of this intervention among outpatients with COVID-19 have not been established. Objective: To assess whether anticoagulant or antiplatelet therapy can safely reduce major adverse cardiopulmonary outcomes among symptomatic but clinically stable outpatients with COVID-19. Design, Setting, and Participants: The ACTIV-4B Outpatient Thrombosis Prevention Trial was designed as a minimal-contact, adaptive, randomized, double-blind, placebo-controlled trial to compare anticoagulant and antiplatelet therapy among 7000 symptomatic but clinically stable outpatients with COVID-19. The trial was conducted at 52 US sites between September 2020 and June 2021; final follow-up was August 5, 2021. Prior to initiating treatment, participants were required to have platelet count greater than 100â¯000/mm3 and estimated glomerular filtration rate greater than 30 mL/min/1.73 m2. Interventions: Random allocation in a 1:1:1:1 ratio to aspirin (81 mg orally once daily; n = 164), prophylactic-dose apixaban (2.5 mg orally twice daily; n = 165), therapeutic-dose apixaban (5 mg orally twice daily; n = 164), or placebo (n = 164) for 45 days. Main Outcomes and Measures: The primary end point was a composite of all-cause mortality, symptomatic venous or arterial thromboembolism, myocardial infarction, stroke, or hospitalization for cardiovascular or pulmonary cause. The primary analyses for efficacy and bleeding events were limited to participants who took at least 1 dose of trial medication. Results: On June 18, 2021, the trial data and safety monitoring board recommended early termination because of lower than anticipated event rates; at that time, 657 symptomatic outpatients with COVID-19 had been randomized (median age, 54 years [IQR, 46-59]; 59% women). The median times from diagnosis to randomization and from randomization to initiation of study treatment were 7 days and 3 days, respectively. Twenty-two randomized participants (3.3%) were hospitalized for COVID-19 prior to initiating treatment. Among the 558 patients who initiated treatment, the adjudicated primary composite end point occurred in 1 patient (0.7%) in the aspirin group, 1 patient (0.7%) in the 2.5-mg apixaban group, 2 patients (1.4%) in the 5-mg apixaban group, and 1 patient (0.7%) in the placebo group. The risk differences compared with placebo for the primary end point were 0.0% (95% CI not calculable) in the aspirin group, 0.7% (95% CI, -2.1% to 4.1%) in the 2.5-mg apixaban group, and 1.4% (95% CI, -1.5% to 5.0%) in the 5-mg apixaban group. Risk differences compared with placebo for bleeding events were 2.0% (95% CI, -2.7% to 6.8%), 4.5% (95% CI, -0.7% to 10.2%), and 6.9% (95% CI, 1.4% to 12.9%) among participants who initiated therapy in the aspirin, prophylactic apixaban, and therapeutic apixaban groups, respectively, although none were major. Findings inclusive of all randomized patients were similar. Conclusions and Relevance: Among symptomatic clinically stable outpatients with COVID-19, treatment with aspirin or apixaban compared with placebo did not reduce the rate of a composite clinical outcome. However, the study was terminated after enrollment of 9% of participants because of an event rate lower than anticipated. Trial Registration: ClinicalTrials.gov Identifier: NCT04498273.

BACKGROUND: Emergency department (ED) visits associated with prescription opioids have increased in the last ten years. This study describes the opioid utilization of patients discharged from the ED with an opioid prescription for pain, 14 to 21â¯days post discharge. METHODS: This is a prospective, single-centered, survey-based observational descriptive study conducted from December 2017 to February 2018 in the ED at a tertiary level 1 trauma center. The primary outcomes were the percentage of patients with unused opioids and the quantity of opioids remaining 14 to 21â¯days post ED discharge. A sample of ED patients who received an oral opioid prescription were approached for informed consent and received a telephone survey 14 to 21â¯days post discharge. RESULTS: Of 178 patients approached for consent, 122 were enrolled. Among them, 98 were successfully surveyed (80.3%). The median number of pills prescribed was 8 (IQR:8-12). Nearly half (49%) of patients had unused opioids 14 to 21â¯days post ED discharge, not including 9.2% of patients who never filled their prescriptions. Of the total 980 pills prescribed, 327 pills remained unused (33.4%). Only 55.1% of patients reported receiving counseling on side effect of opioids and 21.4% of patients reported they received counseling on storage and disposal. CONCLUSION: The majority of patients in this study had unused or unfilled opioids 14 to 21â¯days post ED discharge, and approximately one third of the opioids prescribed remained unused. Most patients did not recall receiving opioid related education including proper disposal of medication.

STUDY OBJECTIVE: Barriers to early antibiotic administration for sepsis remain poorly understood. We investigated the association between emergency department (ED) crowding and door-to-antibiotic time in ED sepsis. METHODS: We conducted a retrospective cohort study of ED sepsis patients presenting to 2 community hospitals, a regional referral hospital, and a tertiary teaching hospital. The primary exposure was ED occupancy rate, defined as the ratio of registered ED patients to licensed ED beds. We defined ED overcrowding as an ED occupancy rate greater than or equal to 1. We used multivariable regression to measure the adjusted association between ED crowding and door-to-antibiotic time (elapsed time from ED arrival to first antibiotic initiation). Using Markov multistate models, we also investigated the association between ED crowding and pre-antibiotic care processes. RESULTS: Among 3,572 eligible sepsis patients, 70% arrived when the ED occupancy rate was greater than or equal to 0.5 and 14% arrived to an overcrowded ED. Median door-to-antibiotic time was 158 minutes (interquartile range 109 to 216 minutes). When the ED was overcrowded, 46% of patients received antibiotics within 3 hours of ED arrival compared with 63% when it was not (difference 14.4%; 95% confidence interval 9.7% to 19.2%). After adjustment, each 10% increase in ED occupancy rate was associated with a 4.0-minute increase (95% confidence interval 2.8 to 5.2 minutes) in door-to-antibiotic time and a decrease in the odds of antibiotic initiation within 3 hours (odds ratio 0.90; 95% confidence interval 0.88 to 0.93). Increasing ED crowding was associated with slower initial patient assessment but not further delays after the initial assessment. CONCLUSION: ED crowding was associated with increased sepsis antibiotic delay. Hospitals must devise strategies to optimize sepsis antibiotic administration during periods of ED crowding.

BACKGROUND AND AIMS: Spontaneous subarachnoid hemorrhage (SAH) from a brain aneurysm, if untreated in the acute phase, leads to loss of functional independence in about 30% of patients and death in 27-44%. To evaluate for SAH, the American College of Emergency Physicians (ACEP) Clinical Policy recommends obtaining a non-contrast brain computed tomography (CT) scan followed by a lumbar puncture (LP) if the CT is negative. On the other hand, current evidence from prospectively collected data suggests that CT alone may be sufficient to rule out SAH in patients who present within 6 h of symptom onset while anecdotal evidence suggests that CT angiogram (CTA) may be used to detect aneurysms, which are the probable cause of SAH. Since many different options are available to emergency physicians, we examined their practice pattern variation by observing their diagnostic approaches and their adherence to the ACEP Clinical Policy. METHODS: We developed, validated, and distributed a survey to emergency physicians at three practice sites: (1) Stanford Healthcare, California, (2) Intermountain Healthcare (five emergency departments), Utah, and (3) Ottawa General Hospital, Toronto. The survey questions examined physician knowledge on CT and LP's test performance and used case-based scenarios to assess diagnostic approaches, variation in practice, and adherence to guidelines. Results were presented as proportions with 95% CIs. RESULTS: Of the 216 physicians surveyed, we received 168 responses (77.8%). The responses by site were: (1) (n = 38, 23.2%), (2) (n = 70, 42.7%), (3) (n = 56, 34.1%). To the CT and LP test performance question, most physicians indicated that CT alone detects > 90% of SAH in those with a confirmed SAH [n = 150 (89.3%, 95% CI 83.6-93.5]. To the case-based questions, most physicians indicated that they would perform a CTA along with a CT [n = 110 (65.5%, 95% CI 57.8-72.6)], some indicated a LP along with a CT [n = 57, 33.9% 95% CI 26.8-41.6)], and a few indicated both a CTA and a LP [n = 16, 9.5%, 95% CI 5.5-15.0]. We also observed practice site variation in the proportion of physicians who indicated that they would use CTA: (1) (n = 25, 65.8%), (2) (n = 54, 77.1%), and (3) (n = 28, 50.0%) (p = 0.006). CONCLUSIONS: Survey responses indicate that physicians use some or all of the imaging tests, with or without LP to diagnose SAH. We observed variation in the use of CTA by site and academic setting and divergence from ACEP Clinical Policy.

OBJECTIVES: A recent study reported a high prevalence of pulmonary embolism (PE) among patients admitted with syncope. We sought to determine whether these findings were validated in our patient population. METHODS: We performed a retrospective, secondary analysis of prospectively gathered data from patients presenting with syncope to an academic emergency department (ED) from July 2010 to December 2015. We analyzed baseline information from the time of the ED visit, recorded outcomes during the hospital stay, and contacted patients by phone at least 30days after the ED visit. The primary study outcome was the diagnosis of acute PE in the ED, during inpatient admission or ED observation unit stay, or by patient report over a 30-day follow-up period. RESULTS: Over the 5.5-year study period, 348 patients with syncope agreed to participate in the study. 52% of patients were female [95% confidence interval (CI): 46.6-57.4] and the average age was 48.4years. Of the enrolled patients, 50.1% (CI: 44.8-55.2) underwent further evaluation for syncope beyond the ED stay: 27% (CI: 22.6-31.9) of patients were admitted to an inpatient unit for further work-up and 23.9% (CI: 19.7-28.6) of patients were placed in the ED observation unit. The overall rate of PE among patients presenting to the ED with syncope was 1.4% (CI: 0.6-3.3%). 2 patients (0.6%, CI: 0.2-2.1) were diagnosed with a PE while in the ED. None of the patients were diagnosed with a PE during hospital admission or the observation stay associated with the index ED visit. 3 patients (0.9%, CI: 0.3-2.5) reported they had been diagnosed with a PE during the 30days following their ED visit, two of whom had been admitted to the hospital at the index ED visit but were not diagnosed with a PE at that time. All patients diagnosed with a PE at the time of the ED visit or during the follow-up period were Pulmonary Embolism Rule Out Criteria (PERC) positive and reported shortness of breath in the ED. CONCLUSION: In contrast to a previous study, our findings do not support a high rate of PE among ED patients presenting with syncope.

BACKGROUND: Pulmonary embolism (PE) clinical decision rules do not consider a patient's family history of venous thromboembolism (VTE). We evaluated whether a family history of VTE predicts acute PE in the emergency department (ED). METHODS: Over a 5.5-year study period, we enrolled a prospective convenience sample of patients presenting to an academic emergency department with chest pain and/or shortness of breath. We defined a family history of VTE as a first-degree relative with previous PE or deep vein thrombosis (DVT). We noted outcomes of testing during the patient's ED stay, including the diagnosis of acute PE by either computed tomography (CT) or ventilation/perfusion (VQ) scan. RESULTS: Of the 3024 study patients, 19.4% reported a family history of VTE and 1.9% were diagnosed with an acute PE during the ED visit. Patients with a family history of VTE were more likely to be diagnosed with a PE: 3.2% vs. 1.6% (pâ¯=â¯0.009). 82.3% of patients were Pulmonary Embolism Rule-out Criteria (PERC) positive, and among PERC-positive patients, those with a family history of VTE were more likely to be diagnosed with a PE: 3.6% vs. 1.9% (pâ¯=â¯0.016). Of patients who underwent testing for PE (33.7%), patients with a family history of VTE were more likely to be diagnosed with a PE: 9.4% vs. 4.9% (pâ¯=â¯0.032). CONCLUSION: Patients with a self-reported family history of VTE in a first-degree relative are more likely to be diagnosed with an acute PE in the ED, even among those patients considered to have a higher likelihood of PE.

BACKGROUND: Limited work has established an objective measure of ECG quality that correlates with physician opinion of the study. We seek to establish a threshold of acceptable ECG data quality for the purpose of ruling out STEMI derived from emergency physician opinion. METHODS: A panel of three emergency physicians rated 240 12-Lead ECGs as being acceptable or unacceptable data quality. Each lead of the ECG had the following measurements recorded: baseline wander, QRS signal amplitude, and artifact amplitude. A lasso regression technique was used to create the model. RESULTS: The area under the curve for the model using all 36 elements is 1.0, indicating a perfect fit. A simplified model using 22 terms has an area under the curve of 0.994. CONCLUSIONS: This study demonstrated that emergency physician opinion of ECG quality for the purpose of ruling out STEMI can be predicted through a regression model.

OBJECTIVE: Because of concerns of high admission rates and adverse events in geriatric patients, hospitals may exclude this group from emergency department observation unit (EDOU) chest pain protocols. We sought to evaluate characteristics and outcomes of geriatric chest pain patients treated in an EDOU. METHODS: We performed a prospective, observational study of chest pain patients admitted to our EDOU over a 36-month period. We recorded baseline demographics and risk factors as well as outcomes related to the EDOU stay. We performed 30-day follow-up using telephone contact and review of the electronic medical record. RESULTS: Over the 36-month study period, 1276 chest pain patients agreed to participate in the study. Two hundred seventy-six patients (21.6%) were 65 years and older. Geriatric patients in the EDOU were more likely to report a history of coronary artery disease than nongeriatric patients (27.1% vs 11.6%, P<.001). There were no clinically significant adverse events nor deaths among geriatric patients. The proportion of geriatric patients who experienced myocardial infarction, stent, or coronary artery bypass graft during the EDOU stay or follow-up period was 4.7% vs 2.7% for nongeriatric patients (P=.09). Inpatient admission rates were significantly higher for geriatric patients (15.6% vs 9.7%, P=.006). Similarly, geriatric patients had higher rates of cardiac catheterization than did nongeriatric patients (13.4% vs 7.9%, P=.005). CONCLUSION: Geriatric patients with chest pain may represent a higher-risk group for evaluation in the EDOU. In our experience, however, these patients were safely evaluated in the EDOU setting and their inpatient admission rate fell within generally accepted guidelines.

The purpose of this study was to design and implement a domestic violence (DV) screening protocol. Trauma patients meeting inclusion criteria (hospitalized > 48 hours) were given a four question DV screen. If abuse was found, a comprehensive DV questionnaire followed. Barriers to screening and results were recorded. Compliance during the pilot test showed 23 of 157 (14.6%) admitted patients were screened. In the implementation year, 446 of 721 (61.9%) were screened. During the 10-month follow-up, 499 of 619 (80.6%) patients were screened. Lack of social work resources was the primary barrier to screening, but compliance increased and was maintained after the study period.

Certain acute coronary syndrome electrocardiographic (ECG) patterns, which do not include ST-segment elevation, are indicative of acute coronary syndrome caused by significant arterial occlusion; these patterns are, of course, associated with significant risk to the patient and mandate a rapid response from the health care team. One such high-risk ECG pattern includes the association of the prominent T wave and J-point depression producing ST-segment depression seen in the precordial leads coupled with ST-segment elevation in lead aVr. This ECG presentation is associated with significant left anterior descending artery obstruction. We report the case of a patient with this ECG presentation who progressed over a very short time to ST-segment elevation myocardial infarction of the anterior wall.

BACKGROUND: Risk of venous thromboembolism (VTE) in many trauma patients extends beyond hospitalization, but there is a paucity of evidence to guide the use of post-discharge prophylaxis (PDP). METHODS: A retrospective cohort study of trauma patients deemed moderate-to-high risk for VTE (risk assessment profile score [RAP] ≥5) who were prescribed PDP based on an internal clinical guideline assessing injury pattern and mobility status. PDP patients were compared with those that did not receive post-discharge prophylaxis (NPDP). RESULTS: 1512 patients were included. PDP group had higher mean RAP score (7.3 vs. 6.4, p â< â0.001), more likely to have a complex orthopedic fracture and underwent a longer median hospital (4.7 vs. 2.9 days, p â< â0.001). No difference between groups in 90-day VTE (11 [1.5 â%] (PDP) vs. 8 [1.0 â%] (NPDP), p â= â0.50), clinically relevant bleeding (p â= â0.58), or readmission (p â= â0.46). CONCLUSIONS: VTE incidence, clinically relevant bleeding, and readmission 90-days after hospital discharge were low and similar between PDP and NPDP groups. PDP prescribed in a presumably higher VTE risk trauma population may mitigate the long-term risk of VTE.

RATIONALE: Sepsis care delivery - including initiation of prompt, appropriate antimicrobials - remains suboptimal. OBJECTIVE: Determine direct and off-target effects of emergency department (ED) sepsis care reorganization. METHODS: This pragmatic pilot trial enrolled adult patients presenting November 2019 to February 2021 to an ED in Utah before and after implementation of a multimodal, team-based "Code Sepsis" protocol. Patients presenting to two other EDs where usual care was continued served as contemporaneous controls. The primary outcome was door-to-antimicrobial time among patients meeting Sepsis-3 criteria before ED departure. Secondary and safety outcomes included all-cause 30-day mortality, antimicrobial utilization and overtreatment, and antimicrobial-associated adverse events. Multivariable regression analyses employed difference-in-differences methods to account for trends in outcomes unrelated to the studied intervention. RESULTS: Code Sepsis protocol activation (N=307) exhibited 8.5% sensitivity and 66% positive predictive value for patients meeting sepsis criteria before ED departure. Among 10,151 patients meeting sepsis criteria during the study, adjusted difference-in-differences analysis demonstrated a 13-minute (95% CI 7-19-minute) decrease in door-to-antimicrobial time associated with Code Sepsis implementation (p<0.001). Mortality and clinical safety outcomes were unchanged, but Code Sepsis implementation was associated with increased false-positive presumptive infection diagnosis among patients meeting sepsis criteria in the ED and increased antimicrobial utilization. CONCLUSIONS: Implementation of a team-based protocol for rapid sepsis evaluation and treatment during the COVID-19 pandemic's first year was associated with decreased ED door-to-antimicrobial time but also increased antimicrobial utilization. Measurement of both patient-centered and off-target effects of sepsis care improvement interventions is essential to comprehensive assessment of their value.

RESUMEN
INTRODUCTION: The modified Brain Injury Guidelines (mBIG) support a subset of low-risk patients to be managed without repeat head computed tomography (RHCT), neurosurgical consult (NSC), or hospital transfer/admission. This pilot aimed to assess mBIG implementation at a single facility to inform future systemwide implementation. METHODS: Single cohort pilot trial at a level I trauma center, December 2021-August 2022. Adult patients included if tICH meeting BIG 1 or 2 criteria. BIG 3 patients excluded. RESULTS: No patients required neurosurgical intervention. 72 RHCT and 83 NSC were prevented. 21 isolated BIG 1 were safely discharged home from the ED. No hospital readmissions for tICH. Protocol adherence rate was 92%. CONCLUSION: Implementation of the mBIG at a single trauma center is feasible and optimizes resource utilization. This pilot study will inform an implementation trial of the mBIG across a 24-hospital integrated health system.

Findings of an enlarged pulmonary artery diameter (PAd) and increased pulmonary artery to ascending aorta ratio (PA:AA) on contrast-enhanced computed tomography pulmonary angiography (CTPA) are associated with increased mortality in particular groups of patients with cardiopulmonary disease. However, the frequency and prognostic significance of these incidental findings has not been studied in unselected patients evaluated in the Emergency Department (ED). This study aims to determine the prevalence and associated prognosis of enlarged pulmonary artery measurements in an ED cohort. We measured PA and AA diameters on 990 CTPA studies performed in the ED. An enlarged PA diameter was defined as >27 mm in females and >29 mm in males, while an increased PA:AA was defined as >0.9. Poisson regression was performed to calculate prevalence ratios for relevant comorbidities, and multivariable Cox regression was performed to calculate hazard ratios (HR) for mortality of patients with enlarged pulmonary artery measurements. An enlarged PAd was observed in 27.9% of 990 patients and was more commonly observed in older patients and in patients with obesity or heart failure. Conversely, PA:AA was increased in 34.2% of subjects, and was more common in younger patients and those with peripheral vascular disease or obesity. After controlling for age, sex, and comorbidities, both enlarged PAd (HR 1.29, 95% CI 1.00-1.68, p = 0.05) and PA:AA (HR 1.70, 95% CI 1.31-2.22 p < 0.01) were independently associated with mortality. In sum, enlarged PAd and increased PA:AA are common in patients undergoing CTPAs in the ED setting and both are independently associated with mortality.
