Impact of early initiation of intravenous therapy for acute decompensated heart failure on outcomes in ADHERE.

BACKGROUND: Since most acute decompensated heart failure (ADHF) patients present for hospital care via the emergency department (ED), we sought to determine the impact of early ED initiation of ADHF-specific therapy, as indicated by nesiritide use, on subsequent outcomes. METHODS: We queried the Acute Decompensated Heart Failure National Registry (ADHERE) to identify patients with initial systolic blood pressure >90 mm Hg and negative cardiac biomarkers, hospitalized after presentation to the ED, who received nesiritide but no other intravenous vasoactive drugs. Intensive care unit use and total hospital length of stay were compared based on the hospital unit where nesiritide therapy was initiated after multivariate adjustment for baseline differences in study populations. RESULTS: Nesiritide was started in the ED in 1,613 patients (EDN group) and after admission to an inpatient unit in 2,687 patients (INN group). EDN patients had higher baseline systolic and diastolic blood pressure (both p < 0.001); while INN patients were more likely to be male and have baseline renal dysfunction (both p < 0.001). Nesiritide was initiated a median of 2.8 and 15.5 h after presentation in EDN and INN patients, respectively (p < 0.001). Compared to INN, EDN patients had a shorter adjusted mean total hospital length of stay (5.4 vs. 6.9 days; p < 0.001), were less likely to require transfer to the intensive care unit from another inpatient unit (odds ratio [OR]: 0.301; 95% confidence interval [CI]: 0.206-0.440), and were more likely to be discharged home (OR: 1.154; 95% CI: 1.005-1.325). CONCLUSIONS: Initiation of ADHF-specific therapy early, while the patient is in the ED, is associated with improved clinical outcomes.

Gender differences in emergency department patients with chronic obstructive pulmonary disease exacerbation.

OBJECTIVES: Although more men are diagnosed as having chronic obstructive pulmonary disease (COPD), its prevalence is increasing among women. Little is known about gender differences in exacerbations of COPD. The objective of this study was to determine if acute presentation, management, and outcomes differ among men and women seeking care in the emergency department (ED) for exacerbation of COPD. METHODS: This was a secondary analysis of a prospective cohort study of ED patients aged 55 years or older who presented with an exacerbation of COPD. Subjects underwent structured interviews in the ED and two weeks later. RESULTS: The cohort consisted of 397 subjects with COPD, of whom 52% were women. Self-report of COPD only tended to be more common among men (61% of men vs. 52% of women), while mixed COPD/asthma tended to be more common among women (39% vs. 48%; p = 0.10). Despite reporting similar chronic symptom severity, women were less likely than men to use anticholinergic agents before their ED visit (59% vs. 69%; p = 0.04). During the exacerbation, women initiated less home therapy and were less likely to seek emergency care within the first 24 hours of symptom onset (25% vs. 36%; p = 0.01). Although ED care and disposition were similar, post-ED outcomes differed. At two-week follow-up, men were more likely to report an ongoing exacerbation (42% vs. 31%; p = 0.03). CONCLUSIONS: Men and women who present to the ED for treatment of an exacerbation of COPD have substantial differences in long-term medication use, self-treatment during exacerbation, delay in emergency care, and post-ED outcomes. Further studies are warranted to confirm and explain these gender-related differences.

Characteristics and outcomes of patients hospitalized for heart failure in the United States: rationale, design, and preliminary observations from the first 100,000 cases in the Acute Decompensated Heart Failure National Registry (ADHERE).

BACKGROUND: The ADHERE is designed to study characteristics, management, and outcomes in a broad sample of patients hospitalized with acute decompensated heart failure. Heart failure is a leading cause of hospitalization for adults older than 65 years in the United States. Most available data on these patients are limited by patient selection criteria and study design of clinical trials and single-center studies. METHODS: Participating hospitals identify patients with a primary or secondary discharge diagnosis of heart failure. Medical history, management, treatments, and health outcomes data are collected through review of medical records and entered into a database via secure web browser technology. RESULTS: As of January 2004, data on 107 362 patients have been received from 282 participating hospitals. Of enrollees with available analyzable data (N = 105 388 from 274 hospitals), the mean age was 72.4 (+/-14.0), and 52% were women. The most common comorbid conditions were hypertension (73%), coronary artery disease (57%), and diabetes (44%). Evidence of mild or no impairment of systolic function was found in 46% of patients. Inhospital mortality was 4.0% and the median hospital length of stay was 4.3 days. CONCLUSIONS: The ADHERE demonstrates both the feasibility and significant implications of gathering representative data on large numbers of patients hospitalized with heart failure. Initial data provided important insights into the clinical characteristics and patterns of care of these patients. Ongoing registry work will provide the framework for improved treatment strategies for patients hospitalized with decompensated heart failure.

Nesiritide added to standard care favorably reduces systolic blood pressure compared with standard care alone in patients with acute decompensated heart failure.

The Prospective Randomized Outcomes study of Acutely decompensated Congestive heart failure Treated Initially as Outpatients with Nesiritide (PROACTION) trial evaluated the safety of nesiritide administration in the emergency department in patients with decompensated heart failure. Patients (N=237) were treated for at least 12 hours with standard care plus either intravenous nesiritide or placebo. Compared to placebo, nesiritide favorably decreased systolic blood pressure (SBP) in patients with elevated baseline SBP, without negatively impacting patients with lower baseline SBP (SBP, >140 mm Hg: nesiritide, -28.7 mm Hg, vs placebo, -8.4 mm Hg [P<.001]; SBP, 101-140 mm Hg: nesiritide, -12.3 mm Hg, vs placebo, -5 mm Hg [P<.017]; SBP, <101 mm Hg: nesiritide, -1.2 mm Hg vs placebo, +16.7 mm Hg [P<.03]). Both treatment groups had similar incidences of symptomatic and asymptomatic hypotension. These data demonstrate that early administration of nesiritide in the emergency department is a safe and effective treatment of heart failure.

Predictors of emergency department observation unit outcomes.

BACKGROUND: Acute decompensated heart failure (adHF) is the cause of approximately 1 million annual hospital admissions. In some of these, the use of a short-stay emergency department observation unit (EDOU) decreases 90-day ED revisits and 90-day rehospitalizations and, if subsequent hospitalization is required, results in shorter stays. OBJECTIVES: To determine whether laboratory and clinical parameters, available at ED arrival, predict successful EDOU discharge. METHODS: This was a 19-month retrospective analysis of adHF EDOU admissions. Details of medical history, clinical course, patient management, laboratory data, and disposition destination were gathered through review of electronic medical records. Recorded laboratory data included measurements of sodium, creatinine, blood urea nitrogen (BUN), hemoglobin, b-type natriuretic peptide, and initial ED systolic blood pressure. Data were analyzed for ability to predict the requirement of hospital admission after EDOU management. RESULTS: There were 385 patients were enrolled. The mean (+/- standard deviation) age was 69.7 (+/- 13.6) years, and 50.1% were female. On ED admission chest radiograph, 69.0% had evidence of pulmonary edema. Elevations in creatinine and BUN levels had statistically significant associations with admission; however, on multivariable analysis, only a BUN value >30 mg/dL significantly predicted EDOU management failure, and subsequent inpatient admission. CONCLUSIONS: These results demonstrate that a BUN level >30 mg/dL is associated with an increased likelihood of admission in patients with adHF. This provides the emergency physician with a practical prognostic tool for disposition planning in congestive heart failure patients.

Emergency department management of patients with acute decompensated heart failure.

The Acute Decompensated HEart Failure National REgistry (ADHERE(R)) confirms that the management of decompensated heart failure is an emergency department (ED) problem, as more than 75% of patients admitted to the hospital with heart failure arrive through the ED. This emphasizes the need for collaboration among emergency medicine, cardiology, nephrology, and hospitalists in the management of acute decompensated heart failure. Such collaboration is important for several reasons, including the enhancement of patient care. It is also known that most hospitals lose money on heart failure admissions. Strategies that can be employed to limit hospital losses on heart failure include reducing admissions from the ED; decreasing the length of hospital stay; increasing the use of the observation unit; reducing re-admissions, particularly through the first 30 days; and reducing the use of high-resource areas such as the intensive care unit (ICU). This article will focus on initiatives that can be implemented in the ED to help with these strategies. In particular, we will discuss early initiation of therapy and its ability to improve length of stay, reduce re-admissions, and reduce ICU admissions. Use of the observation unit for the management of heart failure will also be discussed as a way of decreasing admissions from the ED.

Levalbuterol compared with racemic albuterol in the treatment of acute asthma: results of a pilot study.

This was a prospective, open-label, nonrandomized pilot study to evaluate efficacy and tolerability of levalbuterol (LEV) in acute asthma. Asthmatics (forced expiratory volume in 1 second [FEV1], 20-55% predicted) were sequentially enrolled into cohorts of 12 to 14 and received 0.63, 1.25, 2.5, 3.75, or 5.0 mg LEV or 2.5 or 5.0 mg racemic albuterol (RAC) every 20 minutes x 3. After the first dose, FEV1 changes were 56% (0.6 L) for 1.25 mg LEV and 6% (0.07 L) and 14% (0.21 L) for 2.5 and 5 mg RAC respectively. After three doses, FEV1 changes were 74% (0.9 L), 39% (0.5 L), and 37% (0.6 L) for 1.25 mg, LEV 2.5 mg, RAC and 0.63 mg LEV respectively. LEV doses greater than 1.25 mg did not further improve bronchodilation. Baseline plasma (S)-albuterol levels were negatively correlated with baseline FEV1 (R = - 0.3, P = .004) and percent change in FEV1 (R = -0.3, P = .006). LEV at a dose of 1.25 mg produced effective bronchodilation that was greater than both RAC doses. The negative correlation between (S)-albuterol levels and FEV1 could suggest a deleterious effect of (S)-albuterol. Larger comparative studies are warranted.

Nesiritide in congestive heart failure associated with acute coronary syndromes: a pilot study of safety and efficacy.

BACKGROUND: To compare the safety and efficacy of nesiritide versus intravenous nitroglycerin (NTG) in patients with acute coronary syndromes enrolled in the Vasodilation in the Management of Acute Congestive heart failure trial. Methods and results Retrospective review of Vasodilation in the Management of Acute Congestive heart failure trial data for heart failure associated with prospectively diagnosed acute coronary syndromes. Sixty-one patients were included; 34 received nesiritide and 27 received NTG. Pulmonary capillary wedge pressure was measured in right heart-catheterized patients (11 nesiritide, 9 NTG). Death at 6 months occurred in 2 nesiritide and 5 NTG patients (P>.2). Hypotension occurred in 4 nesiritide and 3 NTG patients (P>.6). At 24 hours, pulmonary capillary wedge pressure improvements persisted (P=.001) in the nesiritide group, whereas the NTG group had returned to baseline (P>.1). In non-right heart-catheterized patients, 24-hour dyspnea scores were at least moderately improved in all nesiritide and 71% of NTG (P=.031). At least minimal dyspnea improvement was seen in 100% of nesiritide versus 71% of NTG patients (P>.3), and 6-hour global clinical scores were at least moderately better in 75% of nesiritide versus 32% of NTG (P=.031). In non-right heart-catheterized patients, there were no 30-day readmissions with nesiritide versus 17% with NTG (P>.2). CONCLUSIONS: Nesiritide is as safe as NTG in heart failure patients with acute coronary syndromes.

Sonographic assessment of the epiglottis.

OBJECTIVES: The ideal diagnostic test for the diagnosis of epiglottitis would be simple, rapid, noninvasive, and highly accurate, performed at the bedside, and would not use ionizing radiation. The purpose of this study was to assess the utility of ultrasound to image the epiglottis and to determine the range of normal epiglottis diameter for men and women. METHODS: This was a prospective study of a convenience sample of 100 subjects between the ages of 18 and 50 years who had no known acute or chronic laryngeal diseases or surgeries. The anterior neck of each subject was scanned in both the long and short axis with a 5-10 MHz linear transducer. Sonographically, the epiglottis appeared as a curvilinear, hypoechoic structure with an echogenic pre-epiglottic space. The sonographic appearance of the epiglottis and the pre-epiglottic space were recorded and anteroposterior measurements of the epiglottis just distal to the hyoid bone were made. Comparisons between men and women were performed with use of a Student's t-test. Pearson's correlation analysis was performed to evaluate the relationship between subject height and epiglottic size. RESULTS: The epiglottis was visualized in all 100 subjects including 62 women and 38 men. The average patient age was 35.2 +/- 8.1 years. The epiglottic thickness was 2.39 +/- 0.15 mm. This was greater in men (2.49 +/- 0.13 mm) than in women (2.34 +/- 0.13 mm) (p < 0.001). There was moderate correlation between height and epiglottic thickness (R = 0.48). However, when this was analyzed separately for men and women, there was no significant correlation between epiglottic thickness and height. CONCLUSIONS: Bedside ultrasonography is easy to perform and can accurately evaluate the epiglottis. Further analysis should include patients with known epiglottic disease to assess the utility of this technique to detect pathologic enlargement.

Prospective multicenter study of relapse following emergency department treatment of COPD exacerbation.

STUDY OBJECTIVES: To determine the incidence and risk factors of relapse after an emergency department (ED) visit for COPD exacerbation. DESIGN: Prospective cohort study as part of the Multicenter Airway Research Collaboration. SETTING: Twenty-nine North American EDs. PATIENTS: ED patients with COPD exacerbations, age > or =55 years. For the present analysis of post-ED relapse, the cohort was restricted to COPD patients who had been discharged from the ED directly to home. MEASUREMENTS AND RESULTS: Eligible patients underwent a structured interview to assess their demographic characteristics, COPD history, and details of the current COPD exacerbation. Data on ED medical management and disposition were obtained by chart review. Patients were contacted by telephone 2 weeks later regarding incident relapse events (ie, urgent clinic or ED visit for worsening COPD). The cohort consisted of 140 COPD patients. Over the next 2 weeks, patients demonstrated a consistent daily relapse rate that summed to 21% (95% confidence interval, 15 to 28%) at day 14. In a multivariate model, the significant risk factors for relapse were the number of urgent clinic or ED visits for COPD exacerbation in the past year (odds ratio [OR], 1.49 [per five visits]), self-reported activity limitation during the past 24 h (OR, 2.93 [per unit on scale of 1 [none] to 4 [severe]), and respiratory rate at ED presentation (OR, 1.76 [per 5 breaths/min]). CONCLUSIONS: Among patients discharged to home after ED treatment of a COPD exacerbation, one in five patients will experience an urgent/emergent relapse event during the next 2 weeks. Both chronic factors (ie, a history of urgent clinic or ED visits) and acute factors (ie, activity limitations and initial respiratory rate) are associated with increased risk. Further research should focus on ways to decrease the relapse rate among these high-risk patients. The clinicians may wish to consider these historical factors when making ED decisions.

Troponin T in elders with suspected acute coronary syndromes.

Troponin T (TnT) elevations (> or =0.1 ng/mL) indicate an increased risk of adverse outcomes in patients with acute coronary syndromes (ACS). There is little data on the prognostic significance of TnT in elders with ACS. We sought to define the ability of TnT to predict adverse outcomes in elders with suspected ACS compared with the younger cohort. This is a nested cohort study of patients aged <65 and > or =65 years with suspected ACS. Serial ECGs, CKMB and TnT assays were obtained at presentation and 4, 8, and 16 hours later. Adverse outcomes at hospital discharge included death, nonfatal myocardial infarction, coronary artery bypass grafting, and positive cardiac catheterization. A total of 695 patients were enrolled. A total of 301 (48%) were aged 65 or older. Although there was no difference in TnT sensitivity between the younger and older cohorts, there was a difference in specificity, 94% versus 83% (P <.01), respectively. In both cohorts, renal insufficiency was associated with a significantly lower TnT specificity. In both elders and younger patients with abnormal renal function, low TnT specificity warrants careful consideration of this marker as the sole criterion for aggressive medical management.

Short-term risk after initial observation for chest pain.

Few studies have evaluated the necessity of immediate stress testing after observation for chest pain. The purpose of this study was to assess the safety of outpatient stress testing after discharge from a chest pain unit. We hypothesized that discharge from a chest pain unit before stress testing is associated with a low rate of short-term adverse outcomes. This was a retrospective chart review of managed care patients discharged from the chest pain unit before the performance of stress testing. Records were reviewed for the occurrence of adverse cardiac outcomes before an outpatient stress test up to 60 days post-discharge. Primary outcomes were defined as death or myocardial infarction, and secondary outcomes as readmission for chest pain evaluation, unstable angina, or congestive heart failure. Three hundred forty-four patients were identified. One hundred sixty-six patients had either a recent prior stress test (17) or an outpatient test (149) performed within 60 days of discharge. During that time, 2 patients (0.6%) had a fatal out-of-hospital cardiac event, and there were 27 subsequent chest pain visits to the Emergency Department by 24 patients (7.0%). Nine patients (2.6%) were admitted to the hospital and 10 (2.9%) were readmitted to the observation unit for chest pain. We conclude that patients who have negative serial electrocardiograms and enzyme testing in a chest pain unit are at low risk for short-term cardiac events. Appropriately selected patients may be discharged for subsequent outpatient testing.

Emergency department management of acute exacerbations of chronic obstructive pulmonary disease in the elderly: the Multicenter Airway Research Collaboration.

OBJECTIVES: To determine adherence of emergency department (ED) management of acute exacerbation of chronic obstructive pulmonary disease (COPD) to current treatment guidelines. DESIGN: A prospective cohort study, as part of the Multicenter Airway Research Collaboration. SETTING: The study was performed at 29 EDs in 15 U.S. states and three Canadian provinces. PARTICIPANTS: ED patients, aged 55 and older, who presented with COPD exacerbation and underwent a structured interview in the ED and another by telephone 2 weeks later. MEASUREMENTS: Adherence of ED management of COPD exacerbation to that recommended in current treatment guidelines. RESULTS: The cohort consisted of 397 subjects, of whom 224 (56%) reported only COPD and 173 (44%) reported asthma and COPD. The average age was 70. Most (80%) patients had used rescue medications in the 6 hours before seeking emergency care. Only 31% were evaluated using spirometry and 48% using arterial blood gas measurement. ED treatment included inhaled short-acting beta-agonists for 91% of patients, inhaled anticholinergics for 77%, methylxanthines for 0.3%, systemic corticosteroids for 62%, and antibiotics for 28%. More than half the patients required hospitalization. At 2-week follow-up, 43% of patients reported a relapse event or ongoing exacerbation. Overall, adherence to national and international guidelines was low. CONCLUSION: Important differences exist between guideline recommendations and actual ED management of COPD exacerbations in older adults. Outcomes after ED treatment are poor and may be related to these shortcomings in quality of care. Better adherence to guideline recommendations when caring for elderly patients with COPD exacerbations may lead to improved clinical outcomes and better resource usage.

A brief risk-stratification tool to predict repeat emergency department visits and hospitalizations in older patients discharged from the emergency department.

OBJECTIVES: To evaluate the predictive ability of a simple six-item triage risk screening tool (TRST) to identify elder emergency department (ED) patients at risk for ED revisits, hospitalization, or nursing home (NH) placement within 30 and 120 days following ED discharge. METHODS: Prospective cohort study of 650 community-dwelling elders (age 65 years or older) presenting to two urban academic EDs. Subjects were prospectively evaluated with a simple six-item ED nursing TRST. Participants were interviewed 30 and 120 days post-ED index visit and the utilization of EDs, hospitals, or NHs was recorded. Main outcome measurement was the ability of the TRST to predict the composite endpoint of subsequent ED use, hospital admission, or NH admission at 30 and 120 days. Individual outcomes of ED use, hospitalization, and NH admissions were also examined. RESULTS: Increasing cumulative TRST scores were associated with significant trends for ED use, hospital admission, and composite outcome at both 30 and 120 days (p < 0.0001 for all, except 30-day ED use, p = 0.002). A simple, unweighted five-item TRST ("lives alone" item removed after logistic regression modeling) with a cut-off score of 2 was the most parsimonious model for predicting composite outcome (AUC = 0.64) and hospitalization at 30 days (AUC = 0.72). Patients defined as high-risk by the TRST (score > or = 2) were significantly more likely to require subsequent ED use (RR = 1.7; 95% CI = 1.2 to 2.3), hospital admission (RR = 3.3; 95% CI = 2.2 to 5.1), or the composite outcome (RR = 1.9; 95% CI 1.7 to 2.9) at both 30 days and 120 days than the low-risk cohort. CONCLUSIONS: Older ED patients with two or more risk factors on a simple triage screening tool were found to be at significantly increased risk for subsequent ED use, hospitalization, and nursing home admission.

Treatment of the acute decompensation of heart failure: efficacy and pharmacoeconomics of early initiation of therapy in the emergency department.

Most patients admitted with acute decompensated heart failure (ADHF) go through the emergency department as their initial point of care. New diagnostic tests hold the promise to improve the clinical accuracy of the emergency physicians' diagnosis. Beyond that there is growing recognition that the treatment provided initially has an important impact on the subsequent inpatient course. Basic care for ADHF has involved oxygen as needed, diuretics, and, occasionally, topical or sublingual nitroglycerin. A substantial proportion of patients are treated with vasoactive agents including inotropes and vasodilators such as nitroglycerin and nesiritide. Unfortunately, inotropes have not been demonstrated to improve the outcome of heart failure and, in fact, may be deleterious. The newer agent, nesiritide, has the advantage of being a balanced vasodilator with favorable effects on diuresis, symptom relief, and neurohormones. Evidence from registries indicates that early initiation of nesiritide compared to delayed initiation leads to improved outcomes with shorter lengths of stay, shorter stays in the intensive care unit, and a lower mortality rate. This article reviews the initial management of ADHF, the role of early initiation of vasodilator therapy, and the pharmacoeconomics of nesiritide treatment.

Direct observation for assessing emergency medicine core competencies: interpersonal skills.

The American Board of Medical Specialties described six core competencies considered essential elements of medical practice: patient care, medical knowledge, practice-based learning and improvement, interpersonal and communication skills, professionalism, and systems-based practice. In response, the Accreditation Council for Graduate Medical Education (ACGME) mandated that all residency programs assess trainees for the newly defined core competencies. Despite the mandate for including these six competencies in residency training, neither a specific curriculum nor a method to assess the outlined objectives has been developed by the ACGME. Instead, it is up to individual residency programs to document how they plan to incorporate and assess the core competencies in their programs. This article describes the potential use of direct observation to assess resident performance in the interpersonal skills core competency.
