An Emergency Department–Based Intensive Care Unit is Associated with Decreased Hospital and Intensive Care Unit Utilization for Diabetic Ketoacidosis

BackgroundMany emergency department (ED) patients in diabetic ketoacidosis (DKA) are admitted to an inpatient intensive care unit (ICU), while ICU capacity is under increasing strain. The Emergency Critical Care Center (EC3), a hybrid ED-ICU setting, opened with the goal of providing rapid initiation of ICU care in the ED.ObjectiveWe sought to evaluate the impact of an ED-ICU on disposition and safety outcomes for adult ED patients in DKA.MethodsThis was a retrospective pre–post cohort of ED visits from 2012–2018 at a single academic medical center. Adult ED patients in DKA (pH < 7.30, HCO₃ < 18 mEq/L, anion gap > 14, and glucose > 250 mg/dL) immediately before (pre-EC3) and after (post-EC3) opening of an ED-ICU were identified. ED disposition and safety data were collected and analyzed.ResultsWe identified 631 patient encounters: 217 pre-EC3 and 414 post-EC3. Baseline demographics were similar between cohorts. Fewer patients in the post-EC3 cohort were admitted to an ICU (11.6% vs. 23.5%, p < 0.001, number needed to treat [NNT] = 8) or general floor bed (58.0% vs. 73.3%, p < 0.001, NNT = 6), and more were discharged from the ED (27.1% vs. 1.4%, p < 0.001, NNT = 4). Rates of hypokalemia (10.1% vs. 6.0%, p = 0.08) and admission to non-ICU with transfer to ICU within 24 h (0.5% vs. 0%, p = 0.30) did not differ.ConclusionManagement of patients with DKA in an ED-ICU was associated with decreased ICU and hospital utilization with similar safety outcomes. Managing rapidly reversible critical illnesses in an ED-ICU may help obviate increasing strain facing many health care systems.     

Estimated plasma volume status (ePVS) could be an easy-to-use clinical tool to determine the risk of sepsis or death in patients with fever

IntroductionCapillary permeability can be increased in patients with sepsis. Indirect estimation of plasma volume status (ePVS) could identify more severely ill patients with fever.Methods1502 patients evaluated for fever at the Emergency Department (ED) of Merano General Hospital (Italy) between June 1, 2018 and May 30, 2019. The ePVS value registered on ED admission and derived from complete blood count was considered. Associations between the ePVS value and the two outcomes of the study (30-day mortality and sepsis diagnosis) were studied.ResultsFifty-one of 1502 patients (3.4%) died at 30 days and 5.3% (80/1502) had a diagnosis of sepsis. The median ePVS in patients who died was higher than in those who survived (6.01 dL/g vs 4.49 dL/g, p < .001). In the multivariate analysis, ePVS higher than 4.52 dL/g presented an OR of 2.717 (CI95% 1.103–6.692, p = .020) for 30-day mortality and 1.824 (CI95% 1.055–3.154, p = .030) for the diagnosis of sepsis. ePVS presented a significant improvement in reclassification of the usual evaluation of patients with fever (NRI 21.6% for 30-day mortality and NRI 19.7 for sepsis diagnosis, p < .001).ConclusionThe ePVS value was a useful additional predictive tool to assess the severity of illness in patients with fever.     

Factors related to the serious adverse events in patients visiting the emergency department after ChAdOx1 and mRNA COVID-19 vaccination

IntroductionWe investigated the clinical characteristics, outcomes and factors related to the serious adverse events (AEs) of patients visiting the emergency department (ED) with various AEs after ChAdOx1 and mRNA COVID-19 vaccination.MethodsPatients with AEs who visited the ED between March 2021 and September 2021 were selected from three EDs. The clinical data of these patients were collected by retrospectively reviewing medical records. Serious adverse events (AEs) were defined as any adverse medical events that led to hospital admission.ResultsA total of 3572 patients visited the ED with AEs; 69.6% were administered mRNA vaccines, and the median (IQR) age was 48 (31–63) years. Regarding chief complaints, chest pain/discomfort (43.7%) was most common in the mRNA vaccines group, while fever (15.8%) was more commonly presented in the ChAdOx1 group. Most patients (93.9%) were discharged from the ED. In multivariate analysis, age ≥70 years, days from vaccination to ED visit ≥8 days, fever and dyspnea as chief complaints were higher independent risk factors for serious AEs (OR 27.94, OR 2.55, OR 1.95 and OR 2.18: p < 0.001, p < 0.001, p = 0.003 and p = 0.003, respectively).ConclusionMost patients who visited the ED with AEs after vaccination were discharged from the ED regardless of the type of vaccine. Emergency physicians need to differentiate serious AEs and consider factors that may require admission to the ED.     

Identification and early anticoagulation in patients with atrial fibrillation in the emergency department

BackgroundEmergency departments (ED) in the United States see more than half a million atrial fibrillation visits a year, however guideline recommended anticoagulation is prescribed in <55% of eligible patients.ObjectiveThe purpose of this study was to measure guideline recommended anticoagulation prescribing in patients with nonvalvular atrial fibrillation (NVAF) presenting to the ED, with the goal of closing any treatment gap established.MethodsWe conducted an observational, prospective cohort study in consecutive patients presenting to the ED with a diagnosis of NVAF. CHA2DS2-VASc and HAS-BLED scores were calculated and used as predefined criteria to establish guideline-based oral anticoagulation compliance in comparing routine care (baseline cohort) versus a multidisciplinary team approach. Transition of Care (TOC) services and follow-up were also provided in the multidisciplinary cohort. The primary endpoint was to compare the proportion of patients on guideline based oral anticoagulant (OAC) therapy at admission and discharge between the groups.ResultsIn the Baseline Cohort (BC) (n = 99), 62.3% of patients with a moderate-high risk of stroke (CHA2DS2-VASc score ≥ 2) were discharged on guideline-based OAC therapy versus 87.8% in the Multidisciplinary Team Cohort (MTC) (n = 131), a 25.5% overall improvement for appropriate anticoagulation (p-value <.001, 95% CI (0.14–0.37)).ConclusionsA multidisciplinary team approach with TOC services for the identification and early intervention of NVAF patients at risk of stroke in the ED can significantly improve the percentage of moderate to high-risk patients that are discharged home with guideline based OAC.     

National ED crowding and hospital quality: results from the 2013 Hospital Compare data

Objectives

We explored Hospital Compare data on emergency department (ED) crowding metrics to assess characteristics of reporting vs nonreporting hospitals, whether hospitals ranked as the US News Best Hospitals (2012-2013) vs unranked hospitals differed in ED performance and relationships between ED crowding and other reported hospital quality measures.

Methods

An ecological study was conducted using data from Hospital Compare data sets released March 2013 and from a popular press publication, US News Best Hospitals 2012 to 2013. We compared hospitals on 5 ED crowding measures: left-without-being-seen rates, waiting times, boarding times, and length of stay for admitted and discharged patients.

Results

Of 4810 hospitals included in the Hospital Compare sample, 2990 (62.2%) reported all ED 5 crowding measures. Median ED length of stay for admitted patients was 262 minutes (interquartile range [IQR], 215-326), median boarding was 88 minutes (IQR, 60-128), median ED length of stay for discharged patients was 139 minutes (IQR, 114-168), and median waiting time was 30 minutes (IQR, 20-44). Hospitals ranked as US News Best Hospitals 2012 to 2013 (n = 650) reported poorer performance on ED crowding measures than unranked hospitals (n = 4160) across all measures. Emergency department boarding times were associated with readmission rates for acute myocardial infarction (r = 0.14, P < .001) and pneumonia (r = 0.17, P < .001) as well as central line–associated bloodstream infections (r = 0.37, P < .001).

Conclusions

There is great variation in measures of ED crowding across the United States. Emergency department crowding was related to several measures of in-patient quality, which suggests that ED crowding should be a hospital-wide priority for quality improvement efforts.     

Predicting 30 – Day outcomes in emergency department patients discharged with COVID-19

IntroductionDetermining disposition for COVID-19 patients can be difficult for emergency medicine clinicians. Previous studies have demonstrated risk factors which predict severe infection and mortality however little is known about which risk factors are associated with failure of outpatient management and subsequent admission for COVID-19 patients.MethodsWe conducted a retrospective observational chart review of patients who had a confirmed positive COVID-19 test collected during an ED visit between March 1, 2020 and October 11, 2020. Patients were divided into two groups based on presence or absence of a subsequent 30-day hospitalization. Clinical and demographic information were collected including chief complaint, triage vital signs and comorbid medical conditions.Results1038 patients were seen and discharged from a network ED with a positive SARS-CoV-2 PCR test. 94 patients (9.1%) were admitted to a hospital within 30 days of the index ED visit while 944 (90.9%) were not admitted to a network hospital within 30 days. Patients that were admitted were more likely to be older (aOR = 1.04 (95% CI 1.03–1.06)), hypoxic (aOR = 2.16 (95% CI 1.14–4.10)) and tachycardic (aOR = 2.13 (95% CI 1.34–3.38)) on initial ED presentation. Preexisting hypertension, diabetes mellitus, coronary artery disease, chronic kidney disease and malignancy were all highly significant risk factors for 30-day hospital admission following initial ED discharge (p < 0.0001).ConclusionEmergency Department providers should consider age, chief complaint, vital signs and comorbid medical conditions when determining disposition for patients diagnosed with COVID-19.     

Factors associated with hospitalization for ischemic stroke and TIA following an emergency department headache visit

BackgroundMisdiagnosis of cerebrovascular disease among Emergency Department (ED) patients with headache has been reported. We hypothesized that markers of substandard diagnostic processes would be associated with subsequent ischemic cerebrovascular events among patients discharged from the ED with a headache diagnosis even after adjusting for demographic variables and medical history.MethodsWe conducted a case-control study of adult ED patients diagnosed with a primary headache disorder at Montefiore Medical Center from 9/1/2013–9/1/2018. Cases were defined as patients hospitalized for an ischemic stroke or TIA within 365 days of their index ED visit. Control patients were defined as those who lacked a subsequent hospitalization for cerebrovascular disease. Pre-specified demographic, clinical, and diagnostic process factors were compared between groups; conditional logistic regression was used to assess the separate and joint influence of baseline features on risk of cerebral ischemia.ResultsA total of 93 consecutive headache patients with a subsequent ischemic stroke/TIA hospitalization were matched to 93 controls (n = 186). Cases were older than controls and more likely to have traditional cerebrovascular risk factors. Neurological consultation was obtained more often for cases (13% vs. 4%; P = 0.03), cases were in the ED for longer (6 vs. 5 h, P = 0.03), and more frequently received neuroimaging (80% vs. 48%; P < 0.0001). Rates of neurological examination, documented differential diagnoses, and clear discharge follow up plans were similar between cases and controls. In our conditional logistic regression model, only history of prior stroke/TIA was associated with increased odds of subsequent cerebral ischemia.ConclusionFactors associated with diagnostic process failures did not increase the odds of subsequent ischemic stroke/TIA hospitalization following ED headache visit in our study.     

Homeless patients tend to have greater psychiatric needs when presenting to the emergency department,

IntroductionHomeless patients tend to visit Emergency Departments (EDs) more frequently than the non-homeless population. The goal of this study was to assess differences in chief complaint, medical conditions, and disposition between homeless patients compared to non-homeless patients presenting to an urban ED.MethodsThis was a retrospective cohort of homeless patients ages ≥18 years compared to non-homeless controls from January 1, 2017 to December 31, 2017. Exclusion criteria were as follows: direct admission to hospital floor, repeat visits, or leaving without being seen. The primary endpoint of this study was to assess differences in chief complaint of homeless versus non-homeless patients upon presentation to the ED. Our secondary endpoints included differences in ED utilization between the two groups, in terms of length of stay, ambulance use, diagnosis, and disposition.ResultsHomeless patients were more likely present to the ED for a psychiatric evaluation (homeless group 34% vs. non-homeless group 4%, p < 0.01) and have a history of a psychiatric diagnosis (56% vs. 10%, p < 0.01) compared to non-homeless controls. Homeless patients also tended to require more ambulance transport (46% vs. 16%, p < 0.01). More homeless patients were transferred to a psychiatric facility (40% vs. 1%, p < 0.01), while the majority of non-homeless patients were discharged home (50% vs. 93%, p < 0.01).ConclusionThis study found that homeless patients had a significantly higher association with psychiatric diagnoses and greater ED utilization than non-homeless. This suggests the importance of increased access to consistent psychiatric care and follow up within the homeless population.     

Patient transfer from a rehabilitation hospital to an emergency department : A retrospective study of an American trauma center

ObjectiveTo analyze medical indications and conditions for patients transferred from a rehabilitation hospital to an emergency department (ED). Are there differences in terms of which patients go to the ED during their stay and which do not? Specifically, what type of patient is most likely to be transferred?MethodologyA retrospective study was conducted at an American adult and pediatric urban trauma center that serves 40,000 patients per year. This study compared randomly selected samples of 534 patients having been transferred to the ED from a rehabilitation hospital and 500 patients who were directly admitted to the ED from the community. Variables examined were: demographics, ED diagnosis and level of care, length of hospital stay, costs, discharge condition and return within 60 days to the ED.ResultsThe patients transferred from the rehabilitation hospital were older (P < 0.01), differed with regard to ethnicity (83% African American; P < 0.01), the reason for hospitalization (P < 0.01; the majority presented with cardiovascular disease, respiratory disease or altered mental status), had longer and more expensive stays (average: 4–8 days, P < 0.01), required a higher level of care (P < 0.01), were more often admitted to surgery or telemetry, and, lastly, were more likely to be discharged in a frail or poor condition (P < 0.01).ConclusionsThe patients transferred from a rehabilitation hospital had complex, intense medical (and often psychological) issues. These patients’ medical needs required a high level of resources in the ED. They frequently left the hospital in sub-optimal conditions, making it likely that they would return to the hospital via the ED prior to completing their treatment within the rehabilitation hospital.     

Evaluation of the effectiveness of peer pressure to change disposition decisions and patient throughput by emergency physician

ObjectivesThe aim of this study was to develop a strategy for imposing peer pressure on emergency physicians to discharge patients and to evaluate patient throughput before and after intervention.MethodsA before-and-after study was conducted in a medical center with more than 120 000 annual emergency department (ED) visits. All nontraumatic adult patients who presented to the ED between 7:30 and 11:30 am Wednesday to Sunday were reviewed. We created a “team norm” imposed peer-pressure effect by announcing the patient discharge rate of each emergency physician through monthly e-mail reminders. Emergency department length of stay (LOS) and 8-hour (the end of shift) and final disposition of patients before (June 1, 2011–September 30, 2011) and after (October 1, 2011–January 30, 2012) intervention were compared.ResultsPatients enrolled before and after intervention totaled 3305 and 2945. No differences existed for age, sex, or average number of patient visits per shift. The 8-hour discharge rate increased significantly for all patients (53.5% vs 48.2%, P < .001), particularly for triage level III patients (odds ratio, 1.3; 95% confidence interval, 1.09-1.38) after intervention and without corresponding differences in the final disposition (P = .165) or admission rate (33.7% vs 31.6%, P = .079). Patients with a final discharge disposition had a shorter LOS (median, 140.4 min vs 158.3 min; P < .001) after intervention.ConclusionsThe intervention strategy used peer pressure to enhance patient flow and throughput. More patients were discharged at the end of shifts, particularly triage level III patients. The ED LOS for patients whose final disposition was discharge decreased significantly.     

One-way-street revisited: Streamlined admission of critically-ill trauma patients

IntroductionEmergency department (ED) crowding is associated with increased mortality and delays in care. We developed a rapid admission pathway targeting critically-ill trauma patients in the ED. This study investigates the sustainability of the pathway, as well as its effectiveness in times of increased ED crowding.Materials & methodsThis was a retrospective cohort study assessing the admission of critically-ill trauma patients with and without the use of a rapid admission pathway from 2013 to 2018. We accessed demographic and clinical data from trauma registry data and ED capacity logs. Statistical analyses included univariate and multivariate testing.ResultsA total of 1700 patients were included. Of this cohort, 434 patients were admitted using the rapid admission pathway, whereas 1266 were admitted using the traditional pathway. In bivariate analysis, mean ED LOS was 1.54 h (95% Confidence Interval [CI]: 1.41, 1.66) with the rapid pathway, compared with 5.88 h (95% CI: 5.64, 6.12) with the traditional pathway (p < 0.01). We found no statistically significant relationship between rapid admission pathway use and survival to hospital discharge. During times of increased crowding, rapid pathway use continued to be associated with reduction in ED LOS (p < 0.01). The reduction in ED LOS was sustained when comparing initial results (2013–2014) to recent data (2015–2018).ConclusionThis study found that a streamlined process to admit critically-ill trauma patients is sustainable and associated with reduction in ED LOS. As ED crowding remains pervasive, these findings support restructured care processes to limit prolonged ED boarding times for critically-ill patients.     

The relationship between patient age and pain management of acute long-bone fracture in the ED

ObjectiveCertain patient populations may be unable to communicate their needs in the emergency department (ED) setting, and the ability to communicate varies between age groups. We aim to determine if there are differences in pain management of acute long-bone fracture (ALBF) among age groups presenting to the ED.MethodsThis study was a retrospective chart review of a consecutive sample of subjects over 13 months. Fracture site, subject age, arrival time, whether pain medication was administered, and time to initial administration were recorded. Subjects were categorized into 3 groups based on age: pediatric (< 18 years), adult (≥ 18 and < 65 years), and geriatric (≥ 65 years).ResultsA total of 1255 patients were included in analysis. One hundred seventy-seven (78.0%) pediatric, 364 (86.5%) adult, and 486 (80.1%) geriatric patients received pain medication during their ED stay. Median and average times to initial pain medication administration with 95% confidence intervals were 44 and 52.0 minutes (45.9-58.1), 39 and 53.6 minutes (48.8-58.4), and 55 and 73.2 minutes (68.1-78.3) for pediatric, adult, and geriatric groups, respectively. A single-factor analysis of variance indicated a significant difference between the groups (P < .01). Student t tests revealed significant differences between pediatric and geriatric groups (P < .01) and adult and geriatric groups (P < .01).ConclusionsAlthough most patients presenting to the ED with ALBF were geriatric, these patients were the least likely to have their pain addressed in a timely fashion. Subgroup analysis of pediatric and geriatric populations indicates significant delay, especially for those ages younger than 3 and 85 years and older. We believe that patients within these groups experience the greatest difficulty communicating their needs effectively due to age-related issues.     

Barriers to medication adherence in the emergency department: A cross-sectional study

BackgroundMedication nonadherence is a common problem that leads to increased healthcare utilization. It is unclear how patient insight and attitude towards their medications affect adherence in the ED. Furthermore, it is unclear how perceived medication importance differs between patients and ED physicians.MethodsWe conducted a cross sectional study of adult patients presenting to 2 academic emergency departments from April 2015 to October 2016. Demographic data were collected and questions were asked regarding medication knowledge, perceived importance, and adherence. We also compared perceived importance of medications between patients and two physician raters. Inter-rater agreement was reported as raw percentages, and categorical data were compared using chi-squared analysis.ResultsWe identified 1268 patients, representing 4634 individual medications. We identified a significant association between knowledge of medications and perceived importance (p < .05). Secondarily, importance level was highly associated with medication adherence (p < .05). When ranking those medications that were considered “least” and “most” important among each patient's med list, our two physicians agreed with patients only 34.1% and 37% of the time respectively, as opposed to 62% and 62.8% agreement between each other.ConclusionsThese data suggest that there is a difference in perceived medication importance between ED physicians and ED patients. Knowledge of a medication's purpose is significantly associated with perceived importance, while this importance appears to be significantly associated with compliance. These results suggest that concerted efforts by ED physicians and staff to educate patients on the utility and importance of their medications may improve adherence.     

Emergency Department Triage Early Warning Score (TREWS) predicts in-hospital mortality in the emergency department

AimThe purpose is to assess the adequacy of the National Early Warning Score (NEWS) in the emergency department (ED) and the usefulness of the Triage in Emergency Department Early Warning Score (TREWS) that has been developed using the NEWS in the ED.MethodsIn this retrospective observational cohort study, we performed univariable and multivariable regression analyses with 81,520 consecutive ED patients to develop a new scoring system, the TREWS. The primary outcome was in-hospital mortality within 24 h, and secondary outcomes were in-hospital mortality within 48 h, 7 days, and 30 days. The prognostic properties of the TREWS were compared with those of the NEWS, Modified Early Warning Score (MEWS), and Rapid Emergency Medicine Score (REMS) using the area under the receiver operating characteristic curve (AUC) technique.ResultsThe AUC of the TREWS for in-hospital mortality within 24 h was 0.906 (95% CI, 0.903–0.908), those of the NEWS, MEWS, and REMS were 0.878 (95% CI, 0.875–0.881), 0.857 (95% CI, 0.854–0.860), and 0.834 (95% CI, 0.831–0.837), respectively. Differences in the AUC between the TREWS and NEWS, the TREWS and MEWS, and the TREWS and REMS were 0.028 (95% CI, 0.022–0.033; p < .001), 0.049 (95% CI, 0.041–0.057; p < .001), and 0.072 (95% CI, 0.063–0.080; p < .001), respectively. The TREWS showed significantly superior performance in predicting secondary outcomes.ConclusionThe TREWS predicts in-hospital mortality within 24 h, 48 h, 7 days, and 30 days better than the NEWS, MEWS, and REMS for patients arriving at the ED.
