RESUMO
Diagnosing patients presenting to the emergency department with self-limited episodes of isolated dizziness (the episodic vestibular syndrome) requires a broad differential diagnosis that includes posterior circulation transient ischemic attack. Because these patients are, by definition, asymptomatic without new neurologic findings on examination, the diagnosis, largely based on history and epidemiologic context, can be challenging. We review literature that addresses the frequency of posterior circulation transient ischemic attack in this group of patients compared with other potential causes of episodic vestibular syndrome. We present ways of distinguishing posterior circulation transient ischemic attack from vestibular migraine, the most common cause of episodic vestibular syndrome. We also present a diagnostic algorithm that may help clinicians to work their way through the differential diagnosis.
RESUMO
The use of a bougie, a flexible endotracheal tube introducer, has been proposed to optimize first-attempt success in emergency department intubations. We aimed to evaluate the available evidence on the association of bougie use in the first attempt and success in tracheal intubations. This was a systematic review and meta-analysis of studies that evaluated first-attempt success between adults intubated with a bougie versus without a bougie (usually with a stylet) in all settings. Manikin and cadaver studies were excluded. A medical librarian searched Ovid Cochrane Central, Ovid Embase, Ovid Medline, Scopus, and Web of Science for randomized controlled trials and comparative observational studies from inception to June 2023. Study selection and data extraction were done in duplicate by 2 independent reviewers. We conducted a meta-analysis with random-effects models, and we used GRADE to assess the certainty of evidence at the outcome level. We screened a total of 2,699 studies, and 133 were selected for full-text review. A total of 18 studies, including 12 randomized controlled trials, underwent quantitative analysis. In the meta-analysis of 18 studies (9,151 patients), bougie use was associated with increased first-attempt intubation success (pooled risk ratio [RR] 1.11, 95% confidence interval [CI] 1.06 to 1.17, low certainty evidence). Bougie use was associated with increased first-attempt success across all analyzed subgroups with similar effect estimates, including in emergency intubations (9 studies; 8,070 patients; RR 1.11, 95% CI 1.05 to 1.16, low certainty). The highest point estimate favoring the use of a bougie was in the subgroup of patients with Cormack-Lehane III or IV (5 studies, 585 patients, RR 1.60, 95% CI 1.40 to 1.84, moderate certainty). In this meta-analysis, the bougie as an aid in the first intubation attempt was associated with increased success. Despite the certainty of evidence being low, these data suggest that a bougie should probably be used first and not as a rescue device in emergency intubations.

OBJECTIVE: To determine the rates of clinically significant tachyarrhythmias and mortality in the management of post-resuscitative shock after return of spontaneous circulation (ROSC) in patients with out-of-hospital cardiac arrest (OHCA) who receive a continuous epinephrine versus norepinephrine infusion. DESIGN: Retrospective cohort study. SETTING: A large multi-site health system with hospitals across the United States. PATIENTS: Adult patients admitted for OHCA with post-resuscitative shock managed with either epinephrine or norepinephrine infusions within 6 h of ROSC. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Between May 5th, 2018, to January 31st, 2022, there were 221 patients admitted for OHCA who received post-resuscitative epinephrine or norepinephrine infusions. There was no difference in the rate of tachyarrhythmias between epinephrine and norepinephrine infusion in univariate (47.1% vs 41.7%, OR 1.24, 95% CI 0.71-2.20) or multivariable analysis (OR 1.34, 95% CI 0.68-2.62). Patients treated with epinephrine were more likely to die during hospitalization than those treated with norepinephrine (90.0% vs 54.3%, OR 6.21, 95% CI 2.37-16.25, p < 0.001). Epinephrine treated patients were more likely to have re-arrest during hospital admission (55.7% vs 14.6%, OR 5.77, 95% CI 2.74-12.18, p < 0.001). CONCLUSION: There was no statistically significant difference in clinically significant cardiac tachyarrhythmias in post-OHCA patients treated with epinephrine versus norepinephrine infusions after ROSC. Re-arrest rates and in-hospital mortality were higher in patients who received epinephrine infusions in the first 6 h post-ROSC. Results of this study add to the literature suggesting norepinephrine may be the vasopressor of choice in post-OHCA patients with post-resuscitative shock after ROSC.

OBJECTIVE: Falls in older adults correlate with heightened morbidity and mortality. Assessing fall risk in the emergency department (ED) not only aids in identifying candidates for prevention interventions but may also offer insights into overall mortality risk. We sought to examine the link between fall risk and 30-day mortality in older ED adults. METHODS: Observational cohort study of adults aged ≥ 75years who presented to an academic ED and who were assessed for fall risk using the Memorial Emergency Department Fall Risk Assessment Tool (MEDFRAT), a validated, ED-specific screening tool. The fall risk was classified as low (0-2 points), moderate (3-4 points), or high (≥5) risk. The primary outcome was 30-day mortality. Hazard ratios (HR) with 95% confidence intervals (CIs) were calculated. RESULTS: A total of 941 patients whose fall risk was assessed in the ED were included in the study. Median age was 83.7 years; 45.6% were male, 75.6% lived in private residences, and 62.7% were admitted. Mortality at 30 days among the high fall risk group was four times that of the low fall risk group (11.8% vs 3.1%; HR 4.00, 95% CI 2.18 to 7.34, p < 0.001). Moderate fall risk individuals had nearly double the mortality rate of the low-risk group (6.0% vs 3.1%), but the difference was not statistically significant (HR 1.98, 95% CI 0.91 to 4.32, p = 0.087). CONCLUSION: ED fall risk assessments are linked to 30-day mortality. Screening may facilitate the stratification of older adults at risk for health deterioration.

PURPOSE: To examine the safety and effectiveness of benzodiazepines (BZD) as compared to antipsychotics for the management of acute agitation in older adults in the emergency department (ED). BASIC PROCEDURES: Retrospective observational cohort study of 21 EDs across four states in the US, including adults ≥60 years old who received either BZD or antipsychotics for acute agitation in the ED and subsequently were admitted to the hospital. Safety was measured as presence of adverse events: respiratory depression, cardiovascular effects, extrapyramidal side effects, or a fall during hospitalization. Effectiveness was measured as indicators of treatment failure: need for additional medication, one-to-one observation, or physical restraints following initial medication administration. Proportions and odds ratios with 95% confidence intervals (CI) were calculated. Univariable and multivariable logistic regression were used to assess the association between potential risk factors and for efficacy and safety endpoints. MAIN FINDINGS: A total of 684 patients were included (63.9% received a BZD and 36.1% an antipsychotic). There was no difference in the incidence of adverse events between groups (20.6% vs 14.6%, difference 6.0%, 95% CI -0.2% to 11.8%), but there was a higher intubation rate in the BZD group (2.7% vs 0.4%, difference 2.3%). There were more treatment failures in the antipsychotic group for the composite primary efficacy endpoint (94.3% vs 87.6%, difference 6.7%, 95% CI 2.5% to 10.9%). This appears to have been driven by the need for 1:1 observation; sensitivity analysis excluding 1:1 observation in the composite outcome demonstrated no significant difference with a failure rate of 38.5% in the antipsychotic group and 35.2% in the benzodiazepine group. PRINCIPAL CONCLUSIONS: Overall there are high rates of treatment failure among agitated older adults receiving pharmacological treatment for agitation in the emergency department. The optimal selection of pharmacological treatment for agitation in older adults should be made considering patient-specific factors that could increase the risk of adverse effects or treatment failure.

BACKGROUND: Andexanet alfa (AA) is approved for reversal of factor Xa inhibitor (FXaI) bleeds; however, there are limited reports of its use for gastrointestinal bleeding (GIB) in real-world populations. The objective of this study was to report real-world utilization and evaluation of the effectiveness of AA for FXaI-associated GIB. METHODS: This retrospective cohort study including consecutive patients receiving AA for FXaI-associated GIB (7/2018-2/2021). Demographics, blood product administration, hemostatic efficacy, rebleeding, thrombosis, and mortality rates were collected. Hemostatic efficacy (HE), based on corrected hemoglobin at 12 h compared to baseline, was categorized as excellent (<10% decrease), good (≤ 20% decrease), or poor (>20% decrease, > 2 units of additional coagulation intervention or death prior to repeat hemoglobin). Comparative transfusion requirements between efficacy groups was assessed by Wilcoxon-Rank test. RESULTS: Twenty-two patients were included (64% male, median (IQR) age 76 years (67, 80). Most patients (59%, n = 13) were on apixaban, and the primary anticoagulation indication was atrial fibrillation (64%, n = 14). Median initial hemoglobin was 7.5 g/dL (IQR 6.4, 8.8) and 50% (n = 11) were upper GIB. Hemostatic efficacy was excellent in 46% (n = 10), good in 23% (n = 5), and poor in 32% (n = 7). There was no statistically significant difference in red blood cells (RBCs) received between those with excellent/good hemostasis (median 2, IQR 1 to 2) and those with poor hemostasis (median 4, IQR 1.5 to 4.5). Two patients (9%) had arterial thrombotic events within 30 days of reversal. CONCLUSION: In this multicenter, single arm, real-world observational analysis of patients with factor Xa inhibitor associated GIB most patients achieved good hemostasis following administration of AA. There was a 9% 30-day thrombotic event rate. The lack of a control group limits the strength of the conclusions that can be drawn from this study.
RESUMO
BACKGROUND: Acute pain accounts for over 70% of Emergency Department (ED) visits. Sub-dissociative dose ketamine (0.1-0.6 mg/kg) is safe and effective for the management of acute pain in the ED. However, the optimal dose of intravenous ketamine that provides effective analgesia and minimizes the risk of adverse effects has yet to be identified. The objective of this study was to describe an effective analgesia dose range of IV ketamine for acute pain in the ED. METHODS: This multi-center, retrospective cohort study evaluated adult patients who received analgesic and sub-dissociative dose ketamine for the management of acute pain between May 5, 2018, and August 30, 2021, in 21 emergency departments at academic, community, and critical access hospitals across four states. Patients were excluded if they received ketamine for an indication other than pain, such as procedural sedation or intubation, or for whom there was incomplete documentation for the primary outcome. Patients who received a ketamine dose <0.3 mg/kg were stratified into the low-dose group, and those who received a dose of 0.3 mg/kg or higher to the high-dose group. The primary outcome was change in pain scores within 60 min using a standard 11-point numeric rating scale (NRS). Secondary outcomes included incidence of adverse effects and use of rescue analgesics. Continuous variables were compared between dose groups using student t-test or Wilcoxon Rank-Sum test. Linear regression was used to assess the association between the change in NRS pain scores within 60 min and dose after adjusting for baseline pain, requiring an additional dose of ketamine, and receiving an opioid. RESULTS: From 3796 patient encounters screened for receipt of ketamine, 384 patients met inclusion criteria including 258 in the low-dose group, and 126 in the high-dose group. The primary reason for exclusion was incomplete documentation of pain scores, or ketamine used for sedation. Median baseline pain scores were 8.2 in the low-dose group and 7.8 in the high-dose group (difference 0.5; 95% CI 0 to 1, p = 0.04). Both groups demonstrated significant reductions in their mean NRS pain scores within 60 min following the first administration of IV ketamine. There were no differences in the change in pain scores between both groups (-2.2 vs -2.6, mean difference 0.4, 95% CI -0.4 to 1.1, p = 0.34). Use of rescue analgesics (40.7% vs 36.5%, p = 0.43) and adverse effects were similar between groups, including early discontinuation of the ketamine infusion (37.2% vs. 37.3%, p = 0.99). Overall, the most common adverse effects were agitation (7.3%) and nausea (7.0%). CONCLUSION: The analgesic efficacy and safety of high-dose sub-dissociative ketamine (≥0.3 mg/kg) was not superior to low-dose (< 0.3 mg/kg) for the management of acute pain in the ED. Low-dose ketamine <0.3 mg/kg is an effective and safe pain management strategy in this population.

BACKGROUND: Medical encounters require an efficient and focused history of present illness (HPI) to create differential diagnoses and guide diagnostic testing and treatment. Our aim was to compare the HPI of notes created by an automated digital intake tool versus standard medical notes created by clinicians. METHODS: Prospective trial in a quaternary academic Emergency Department (ED). Notes were compared using the 5-point Physician Documentation Quality Instrument (PDQI-9) scale and the Centers for Medicare & Medicaid Services (CMS) level of complexity index. Reviewers were board certified emergency medicine physicians blinded to note origin. Reviewers received training and calibration prior to note assessments. A difference of 1 point was considered clinically significant. Analysis included McNemar's (binary), Wilcoxon-rank (Likert), and agreement with Cohen's Kappa. RESULTS: A total of 148 ED medical encounters were charted by both digital note and standard clinical note. The ability to capture patient information was assessed through comparison of note content across paired charts (digital-standard note on the same patient), as well as scores given by the reviewers. Reviewer agreement was kappa 0.56 (CI 0.49-0.64), indicating moderate level of agreement between reviewers scoring the same patient chart. Considering all 18 questions across PDQI-9 and CMS scales, the average agreement between standard clinical note and digital note was 54.3% (IQR 44.4-66.7%). There was a moderate level of agreement between content of standard and digital notes (kappa 0.54, 95%CI 0.49-0.60). The quality of the digital note was within the 1 point clinically significant difference for all of the attributes, except for conciseness. Digital notes had a higher frequency of CMS severity elements identified. CONCLUSION: Digitally generated clinical notes had moderate agreement compared to standard clinical notes and within the one point clinically significant difference except for the conciseness attribute. Digital notes more reliably documented billing components of severity. The use of automated notes should be further explored to evaluate its utility in facilitating documentation of patient encounters.

STUDY OBJECTIVE: To evaluate the association between delirium and subsequent short-term mortality in geriatric patients presenting to the emergency department (ED). METHODS: This was an observational cohort study of adults age ≥75 years who presented to an academic ED and were screened for delirium during their ED visit. The Delirium Triage Screen followed by the Brief Confusion Assessment Method were used to ascertain the presence of delirium. In-hospital, 7-day, and 30-day mortality were compared between patients with and without ED delirium. Odds ratios with 95% confidence intervals (CIs) were calculated through logistic regression after adjusting for confounders including age, sex, history of dementia, ED disposition, and acuity. RESULTS: A total of 967 ED visits were included for analysis among which delirium was detected in 107 (11.1%). The median age of the cohort was 83 years (IQR 79, 88), 526 (54.4%) were female, 285 (29.5%) had documented dementia, and 171 (17.7%) had a high acuity Emergency Severity Index triage level 1 or 2. During the hospitalization, 5/107 (4.7%) of those with delirium and 4/860 (0.5%) of those without delirium died. Within 7 days of ED departure, 6/107 (5.6%) of those with delirium and 6/860 (0.7%) of those without delirium died (unadjusted OR 8.46, 95% CI 2.68-26.71). Within 30 days, 18/107 (16.8%) of those with delirium and 37/860 (4.3%) of those without delirium died (unadjusted OR 4.50, 95% CI 2.46-8.23). ED delirium remained associated with higher 7-day (adjusted OR 5.23, 95% CI 1.44-19.05, p = 0.008) and 30-day mortality (adjusted OR 2.82, 95% CI 1.45-5.46, p = 0.002). CONCLUSION: Delirium is an important prognostic factor that ED clinicians and nurses must be aware of to optimize delirium prevention, management, disposition, and communication with patients and families.

In clinical scenario surveys, inpatient providers were more likely to report continuing inappropriate (odds ratio, 2.02 [95% confidence interval, 1.35-3.03]; P<.001) or broad-spectrum (1.8 [1.27-2.56]; P=.001) antibiotic therapy when initiated by emergency department providers, than to change to appropriate or narrow-spectrum therapy, respectively. Antibiotic inertia could represent a significant antibiotic stewardship target.

STUDY OBJECTIVE: The aim of this study was to evaluate the impact of pharmacist presence or pharmacist-led antimicrobial stewardship interventions on appropriate prescribing of antibiotics in the emergency department (ED). METHODS: Systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were conducted. Studies describing the role of pharmacists and their association with antimicrobial stewardship in the ED were included. The comparator for pharmacist intervention was hours without a pharmacist present, preprotocol implementation, and nonpharmacist culture follow-up. RESULTS: In total, 24 studies (9,984 patients) were included in the qualitative synthesis, and 22 studies (5,791 patients) had data for the primary outcome and were included for the quantitative assessment (meta-analysis). Appropriate prescribing of antibiotics was more likely with pharmacist intervention (22 studies; odds ratio [OR], 3.47; 95% confidence interval [CI] 2.39 to 5.03), particularly among patients with pneumonia (5 studies; OR, 3.74; 95% CI 2.14 to 6.54) or urinary tract infection (4 studies; OR, 1.76; 95% CI 1.24 to 2.50). Time to culture review was similar with or without pharmacist intervention. Time to appropriate antibiotic was shorter with pharmacist intervention (mean difference, 18.9 hours; 95% CI 11.9 to 25.9; P<.001). Repeat ED visit for the same complaint was not significant (10 studies; OR, 0.65; 95% CI 0.39 to 1.10). CONCLUSION: Pharmacist presence and pharmacist-led antimicrobial stewardship interventions appear to be effective for the appropriate prescribing of antibiotics in adult patients presenting to EDs with a variety of infectious syndromes.

OBJECTIVE: To assess the QTc interval variation after low-dose droperidol in a population of undifferentiated, stable, and non-agitated patients receiving droperidol in the emergency department. METHODS: Prospective cohort study of patients aged ≥12 years of age who received low-dose droperidol (≤ 2.5 mg) for indications other than acute behavioral disturbances. QTc intervals were monitored in real-time during pre-specified observation periods in the ED. Primary outcome was variation of QTc interval after droperidol administration, defined as the maximum delta (change) of QTc interval. Other outcomes included proportion of patients with a QTc ≥ 500 ms after droperidol, delta ≥ +60 ms, and incidence of clinical adverse events. Patients were monitored up to 30 min after IV bolus and up to 46 min after infusion. RESULTS: A total of 68 patients were included (mean age 42.1 years, 66.2% females). The median dose of droperidol was 1.875 mg (range 0.625 mg, 2.5 mg) and 94.1% received droperidol for headache management. Most patients received droperidol as a 2-min bolus (n = 41, 60.3%). The mean maximum delta of QTc interval after droperidol across all 68 patients was +29.9 ms (SD 15). A total of 12 patients (17.6%) experienced a QTc interval ≥ 500 ms during the observation period after droperidol, and 3 patients (4.4%) had a delta QTc ≥ +60 ms. There were no serious arrhythmias, such as TdP, or deaths among the 68 participants in this study (0/68). However, 13.2% (n = 9) had at least one non-serious adverse event including restlessness and/or anxiety. CONCLUSION: The QTc interval slightly increased after droperidol administration, but these prolongations were brief, mostly below 500 msec and did not lead to serious arrhythmias. The yield of continuous cardiac monitoring in patients receiving low doses of droperidol is likely low.

OBJECTIVES: To evaluate the short-term mortality of adult patients presenting to the emergency department (ED) with altered mental status (AMS) as compared to other common chief complaints. METHODS: Observational cohort study of adult patients (age ≥ 40) who presented to an academic ED over a 1-year period with five pre-specified complaints at ED triage: AMS, generalized weakness, chest pain, abdominal pain, and headache. Primary outcomes included 7 and 30-day mortality. Hazard ratios (HR) were calculated with 95% confidence intervals (CI) using Cox proportional hazards models adjusted for age, acuity level, and comorbidities. RESULTS: A total of 9850 ED visits were included for analysis from which 101 (1.0%) and 295 (3.0%) died within 7 and 30 days, respectively. Among 683 AMS visits, the 7-day mortality rate was 3.2%. Mortality was lower for all other chief complaints, including generalized weakness (17/1170, 1.5%), abdominal pain (32/3609, 0.9%), chest pain (26/3548, 0.7%), and headache (4/840, 0.5%). After adjusting for key confounders, patients presenting with AMS had a significantly higher risk of death within 7 days of ED arrival than patients presenting with chest pain (HR 3.72, 95% CI 2.05 to 6.76, p < .001). Similarly, we found that patients presenting with AMS had a significantly higher risk of dying within 30 days compared to patients with chest pain (HR 3.65, 95% CI 2.49 to 5.37, p < .001), and headache (HR 2.09, 95% CI 1.09 to 4.01, p = .026). Differences were not statistically significant for comparisons with abdominal pain and generalized weakness, but confidence intervals were wide. CONCLUSION: Patients presenting with AMS have worse short-term prognosis than patients presenting to the ED with chest pain or headache. AMS may indicate an underlying brain dysfunction (delirium), which is associated with adverse outcomes and increased mortality.

STUDY OBJECTIVE: To evaluate the association between potential emergency department (ED)-based modifiable risk factors and subsequent development of delirium among hospitalized older adults free of delirium at the time of ED stay. METHODS: Observational cohort study of patients aged ≥75 years who screened negative for delirium in the ED, were subsequently admitted to the hospital, and had delirium screening performed within 48 h of admission. Potential ED-based risk factors for delirium included ED length of stay (LOS), administration of opioids, benzodiazepines, antipsychotics, or anticholinergics, and the placement of urinary catheter while in the ED. Odds ratios (OR) and mean differences (MD) with 95% confidence intervals (CIs) were calculated. RESULTS: Among 472 patients without delirium in the ED (mean age 84 years, 54.2% females), 33 (7.0%) patients developed delirium within 48 h of hospitalization. The ED LOS of those who developed delirium was similar to those who did not develop delirium (312.1 vs 325.6 min, MD -13.5 min, CI -56.1 to 29.0). Patients who received opioids in the ED were as likely to develop delirium as those who did not receive opioids (7.2% vs 6.9%: OR 1.04, CI 0.44 to 2.48). Patients who received benzodiazepines had a higher risk of incident delirium, the difference was clinically but not statistically significant (37.3% vs 6.5%, OR 5.35, CI 0.87 to 23.81). Intermittent urinary catheterization (OR 2.05, CI 1.00 to 4.22) and Foley placement (OR 3.69, CI 1.55 to 8.80) were associated with a higher risk of subsequent delirium. After adjusting for presence of dementia, only Foley placement in the ED remained significantly associated with development of in-hospital delirium (adjusted OR 3.16, CI 1.22 to 7.53). CONCLUSION: ED LOS and ED opioid use were not associated with higher risk of incident delirium in this cohort. Urinary catheterization in the ED was associated with an increased risk of subsequent delirium. These findings can be used to design ED-based initiatives and increase delirium prevention efforts.

We conducted a systematic review and meta-analysis to identify risk factors for delirium in geriatric patients in the emergency department and to identify emergency department (ED)-based modifiable risk factors for developing delirium during hospitalization. We searched evidence based medicine reviews, EMBASE, MEDLINE, Scopus, and Web of Science for observational studies from the time of their inception to July 2020. We included studies that evaluated potential risk factors for either prevalent or incident delirium among older adults (age ≥ 60 years) presenting to the ED. When appropriate, we meta-analyzed estimates for risk factors using a random-effects model. The certainty of evidence was evaluated using the grading of recommendations assessment, development and evaluation approach. The study's protocol was registered in PROSPERO (CDR42020175261). A total of 4,513 citations were reviewed, and 34 studies met the criteria for inclusion: 27 evaluating risk factors for ED delirium (13,412 patients) and 7 evaluating ED-based risk factors for developing delirium during hospitalization (2,238 patients). The prevalence of ED delirium ranged from 7% to 35%. Four factors had strong associations with ED delirium and were graded as high-certainty evidence, including nursing home residence (4 studies; odds ratio [OR], 3.45; 95% confidence interval [CI], 2.17 to 5.48), cognitive impairment (7 studies; OR, 4.46; 95% CI, 3.38 to 5.89), hearing impairment (3 studies, OR, 2.57; 95% CI, 1.03 to 6.41), and a history of stroke (3 studies; OR, 3.20; 95% CI, 1.17 to 8.75). The rate of developing delirium during hospitalization ranged from 11% to 27%. A length of stay of more than 10 hours in ED was associated with a higher risk of delirium (1 study; OR, 2.23; 95% CI, 1.13 to 4.41). One study reported that severe pain, rather than the use of opioids, was associated with the development of delirium. These findings can be used to prioritize delirium screening in the ED and develop novel ED delirium risk scores or prevention interventions.

OBJECTIVE: To identify predictors of 30-day emergency department (ED) return visits in patients age 65-79 years and age ≥ 80 years. METHODS: This was a cohort study of older adults who presented to the ED over a 1-year period. A mixed-effects logistic regression model was used to identify predictors for returning to the ED within 30 days. We stratified the cohort into those aged 65-79 years and aged ≥80 years. Adjusted odds ratios (aORs) with 95% confidence intervals (CI) were reported. This study adhered to the STROBE reporting guidelines. RESULTS: A total of 21,460 ED visits representing 14,528 unique patients were included. The overall return rate was 15% (1998/13,300 visits) for age 65-79 years, and 16% (1306/8160 visits) for age ≥ 80 years. A history of congestive heart failure (CHF), dementia, or prior hospitalization within 2 years were associated with increased odds of returning in both age groups (for age 65-79: CHF aOR 1.36 [CI 1.16-1.59], dementia aOR 1.27 [CI 1.07-1.49], prior hospitalization aOR 1.36 [CI 1.19-1.56]; for age ≥ 80: CHF aOR 1.32 [CI 1.13-1.55], dementia aOR 1.22 [CI 1.04-1.42], and prior hospitalization aOR 1.27 [CI 1.09-1.47]). Being admitted from the ED was associated with decreased odds of returning to the ED within 30 days (aOR 0.72 [CI 0.64-0.80] for age 65-79 years and 0.72 [CI 0.63-0.82] for age ≥ 80). CONCLUSION: Age alone was not an independent predictor of return visits. Prior hospitalization, dementia and CHF were predictors of 30-day ED return. The identification of predictors of return visits may help to optimize care transition in the ED.

OBJECTIVES: To describe the emergency department (ED) triage of anaphylaxis patients based on the Emergency Severity Index (ESI), assess the association between ESI triage level and ED epinephrine administration, and determine characteristics associated with lower acuity triage ESI assignment (levels 3 and 4). METHODS: We conducted a cohort study of adult and pediatric anaphylaxis patients between September 2010 and September 2018 at an academic ED. Patient characteristics and management were compared between Emergency Severity Index (ESI) triage level 1 or 2 versus levels 3 or 4 using logistic regression analysis. We adhered to STROBE reporting guidelines. RESULTS: A total of 1090 patient visits were included. There were 26 (2%), 515 (47%), 489 (45%), and 60 (6%) visits that were assigned an ESI triage level of 1, 2, 3, and 4, respectively. Epinephrine was administered in the ED to 53% of patients triaged ESI level 1 or 2 and to 40% of patients triaged ESI level 3 or 4. Patients who were assigned a lower acuity ESI level of 3 or 4 had a longer median time from ED arrival to epinephrine administration compared to those with a higher acuity ESI level of 1 or 2 (28 min compared to 13 min, p < .001). A lower acuity ESI level was more likely to be assigned to visits with a chief concern of hives, rash, or pruritus (OR 2.33 [95% CI, 1.20-4.53]) and less likely to be assigned to visits among adults (OR, 0.43 [0.31-0.60]), patients who received epinephrine from emergency medical services (OR 0.56 [0.38-0.82]), presented with posterior pharyngeal or uvular angioedema (OR, 0.56 [0.38-0.82]), hypoxemia (OR, 0.34 [0.18-0.64]), or increased heart (OR 0.83 [0.73-0.95]) or respiratory (OR 0.70 [0.60-0.82]) rates. CONCLUSION: Patients triaged to lower acuity ESI levels experienced delays in ED epinephrine administration. Adult and pediatric patients with skin-related chief concerns were more likely to be to be assigned lower acuity ESI levels. Further studies are needed to identify interventions that will improve ED anaphylaxis triage.

OBJECTIVE: To compare resource utilization and mortality between older and younger adult patients with similar ED chief complaints and ESI triage levels. METHODS: This was an observational study of consecutive adult patients (age ≥ 40) who presented to an academic ED over a 1-year period with chest pain, abdominal pain, altered mental status, generalized weakness, or headache. Patients were categorized into 40-64, 65-79, and ≥ 80-year old groups. Mortality and utilization outcomes were compared between age groups through logistic regression models or Cox proportional hazards adjusting for ESI level and chief complaint. Odds ratios (OR) and hazard ratios (HR) were calculated with 95% confidence intervals (CI). RESULTS: A total of 9798 ED visits were included. As compared to younger adults (age 40-64), older adults, independently of ESI level and chief complaint, had higher ED laboratory use (OR 1.46 [CI 1.29, 1.66] for age 65-80; OR 1.33 [CI 1.15, 1.55] for age ≥ 80), ED radiology use (OR 1.40 [CI 1.26, 1.56]; OR 1.48 [CI 1.30, 1.69]), hospital admission (OR 1.56 [CI 1.42, 1.72]; OR 1.97 [CI 1.75, 2.21]), and ICU admission (OR 1.38 [CI 1.15, 1.65]; OR 1.23 [CI 0.99, 1.52]). Despite similar ESI and chief complaint, patients age 65-79 and ≥ 80 had higher 30-day mortality rates (HR 1.87 [CI 1.39 to 2.51] and 2.47 [CI 1.81 to 3.37], respectively). CONCLUSIONS: Older adults with similar chief complaints and ESI levels than younger adults, have significantly higher ED resource use, hospitalization rates, and mortality.

OBJECTIVE: Determine if a comfort cart would improve older adults' comfort and facilitate communication during Emergency Department (ED) visits. METHODS: A comfort cart containing low-cost, non-pharmacological interventions to improve patient comfort and ability to communicate (e.g., hearing amplifiers, reading glasses) were made available to patients aged ≥65 years. Patients and clinicians were surveyed to assess effectiveness. We followed the Standards for Quality Improvement Reporting Excellence: SQUIRE 2.0 guidelines. RESULTS: Three hundred patients and 100 providers were surveyed. Among patients, 98.0%, 95.1%, and 67.5% somewhat or strongly agreed that the comfort cart improved comfort, overall experience, and independence, respectively. Among providers, 97.0%, 95.0%, 87.0%, and 83% somewhat or strongly agreed that the comfort cart provided comfort, improved patient satisfaction, increased ability to give compassionate care, and increased patient orientation. CONCLUSION: The comfort cart was an affordable and effective intervention that improved patients' comfort by facilitating communication, wellbeing, and compassionate care delivery.

BACKGROUND: Urinary tract infection (UTI) is the second most common infection requiring intensive care unit (ICU) admission in emergency department (ED) patients. Optimal empiric management for health care-associated (HCA) UTI is unclear, particularly in the critically ill. OBJECTIVE: To compare clinical failure of broad vs. narrow antibiotic selection in the ED for patients presenting with HCA UTI admitted to the ICU. METHODS: Observational cohort of patients started on empiric antibiotic for UTI with at least one HCA risk factor (recurrent UTI, chronic urinary catheter or dialysis, urologic procedures, previous antibiotic exposure, hospitalization, or group facility residence). Broad antibiotics covered Pseudomonas spp. and extended-spectrum beta-lactamase. Clinical failure was a composite of multiorgan dysfunction (MODS) by day 2 and in-hospital mortality. Secondary outcomes were length of stay (LOS), readmission, recurrent infection, development of multidrug-resistant organisms, and Clostridium difficile infection. Associations were reported with odds ratios (OR) and 95% confidence intervals (CI). RESULTS: There were 272 patients included; 196 (72.1%) received broad and 76 (27.9%) received narrow therapy. There was no association between antibiotic selection and clinical failure (OR 1.05, 95% CI 0.5-2.25, p = 0.89) or between antibiotic selection and number of HCA risk factors (OR 0.98, 95% CI 0.73-1.31, p = 0.87). There was an association between clinical failure and MODS on ICU admission (OR 9.14, 95% CI 4.70-17.78, p < 0.001). Hospital LOS and readmission did not differ between antibiotic groups. CONCLUSION: Initial empiric broad or narrow antibiotic coverage in HCA UTI patients who presented to the ED and required ICU admission had similar clinical outcomes.
