Cardiac Arrest: A Treatment Algorithm for Emergent Invasive Cardiac Procedures in the Resuscitated Comatose Patient.

Patients who are comatose after cardiac arrest continue to be a challenge, with high mortality. Although there is an American College of Cardiology Foundation/American Heart Association Class I recommendation for performing immediate angiography and percutaneous coronary intervention (when indicated) in patients with ST-segment elevation myocardial infarction, no guidelines exist for patients without ST-segment elevation. Early introduction of mild therapeutic hypothermia is an established treatment goal. However, there are no established guidelines for risk stratification of patients for cardiac catheterization and possible percutaneous coronary intervention, particularly in patients who have unfavorable clinical features in whom procedures may be futile and affect public reporting of mortality. An algorithm is presented to improve the risk stratification of these severely ill patients with an emphasis on consultation and evaluation of patients prior to activation of the cardiac catheterization laboratory.

Impact of an Emergency Department Observation Unit Transient Ischemic Attack Protocol on Length of Stay and Cost

This study examined the impact of an emergency department (ED) observation units accelerated diagnostic protocol (ADP) on hospital length of stay (LOS), cost of care, and clinical outcome of patients who had sustained a transient ischemic attack (TIA). All patients with TIA presenting to the ED over a 18-consecutive month period were eligible for the study. During the initial 11 months of the study (pre-ADP period), all patients were admitted to the neurology service. Over the subsequent 7 months (post-ADP period), patients were either managed using the ADP or were admitted based on ADP exclusion criteria or at a physicians discretion. All patients had orders for serial clinical examinations, neurologic evaluation, cardiac monitoring, vascular imaging of the brain and neck, and echocardiography. A total of 142 patients were included in the study (mean age, 67.9 ± 13.9 years; 61% female; mean ABCD(2) score, 4.3 ± 1.4). In the post-ADP period, 68% of the patients were managed using the ADP. Of these patients, 79% were discharged with a median LOS of 25.5 hours (ED + observation unit). Compared with the pre-ADP patients, the post-ADP patients (ADP and non-ADP) had a 20.8-hour shorter median LOS (95% confidence interval, 16.3-25.1 hours; P < .01) than pre-ADP patients and lower median associated costs (cost difference,

2238). The stroke rate at 90 days was low in both groups (pre-ADP, 0%; post-ADP, 1.2%). Our findings indicate that introduction of an ED observation unit ADP for patients with TIA at a primary stroke center is associated with a significantly shorter LOS and lower costs compared with inpatient admission, with comparable clinical outcomes.

Ability of triage decision rules for rapid electrocardiogram to identify patients with suspected ST-elevation myocardial infarction.

The diagnosis of patients with acute chest pain remains a challenging problem. There are approximately 6 million chest pain related emergency department (ED) visits annually in the US alone [1]. Approximately 5.3% of all ED patients are seen because of chest pain and reported admission rates are between 30% and 72% for these patients [2]. Only 15–25% of patients presenting with acute chest pain are ultimately diagnosed as having an acute coronary syndrome (ACS). Of those patients who were admitted to the chest pain unit, 44% ultimately had

Fundus Photography vs. Ophthalmoscopy Outcomes in the Emergency Department (FOTO-ED) Phase III: Web-based, In-service Training of Emergency Providers

STUDY OBJECTIVE During the first phase of the Fundus Photography vs Ophthalmoscopy Trial Outcomes in the Emergency Department study, 13% (44/350; 95% confidence interval [CI] 9% to 17%) of patients had an ocular fundus finding, such as papilledema, relevant to their emergency department (ED) management found by nonmydriatic ocular fundus photography reviewed by neuro-ophthalmologists. All of these findings were missed by emergency physicians, who examined only 14% of enrolled patients by direct ophthalmoscopy. In the present study, we evaluate the sensitivity of nonmydriatic ocular fundus photography, an alternative to direct ophthalmoscopy, for relevant findings when photographs are made available for use by emergency physicians during routine clinical care. METHODS Three hundred fifty-four patients presenting to our ED with headache, focal neurologic deficit, visual change, or diastolic blood pressure greater than or equal to 120 mm Hg had nonmydriatic fundus photography obtained (Kowa nonmydriatic α-D). Photographs were placed on the electronic medical record for emergency physician review. Identification of relevant findings on photographs by emergency physicians was compared with a reference standard of neuro-ophthalmologist review. RESULTS Emergency physicians reviewed photographs of 239 patients (68%). Thirty-five patients (10%; 95% CI 7% to 13%) had relevant findings identified by neuro-ophthalmologist review (6 disc edema, 6 grade III/IV hypertensive retinopathy, 7 isolated hemorrhages, 15 optic disc pallor, and 1 retinal vascular occlusion). Emergency physicians identified 16 of 35 relevant findings (sensitivity 46%; 95% CI 29% to 63%) and also identified 289 of 319 normal findings (specificity 91%; 95% CI 87% to 94%). Emergency physicians reported that photographs were helpful for 125 patients (35%). CONCLUSION Emergency physicians used nonmydriatic fundus photographs more frequently than they performed direct ophthalmoscopy, and their detection of relevant abnormalities improved. Ocular fundus photography often assisted ED care even when results were normal. Nonmydriatic ocular fundus photography offers a promising alternative to direct ophthalmoscopy.

A Comprehensive Acute Coronary Syndrome Algorithm for Centers With Percutaneous Coronary Intervention Capability

Introduction Physicians dedicate substantial time to documentation. Scribes are sometimes used to improve efficiency by performing documentation tasks, although their impacts have not been prospectively evaluated. Our objective was to assess a scribe program’s impact on emergency department (ED) throughput, physician time utilization, and job satisfaction in a large academic emergency medicine practice. Methods We evaluated the intervention using pre- and post-intervention surveys and administrative data. All site physicians were included. Pre- and post-intervention data were collected in four-month periods one year apart. Primary outcomes included changes in monthly average ED length of stay (LOS), provider-specific average relative value units (RVUs) per hour (raw and normalized to volume), self-reported estimates of time spent teaching, self-reported estimates of time spent documenting, and job satisfaction. We analyzed data using descriptive statistics and appropriate tests for paired pre-post differences in continuous, categorical, and ranked variables. Results Pre- and post-survey response rates were 76.1% and 69.0%, respectively. Most responded positively to the intervention, although 9.5% reported negative impressions. There was a 36% reduction (25%–50%; p<0.01) in time spent documenting and a 30% increase (11%–46%, p<0.01) in time spent in direct patient contact. No statistically significant changes were seen in job satisfaction or perception of time spent teaching. ED volume increased by 88 patients per day (32–146, p=0.04) pre- to post- and LOS was unchanged; rates of patients leaving against medical advice dropped, and rates of patients leaving without being seen increased. RVUs per hour increased 5.5% and per patient 5.3%; both were statistically significant. No statistically significant changes were seen in patients seen per hour. There was moderate correlation between changes in ED volume and changes in productivity metrics. Conclusion Scribes were well received in our practice. Documentation time was substantially reduced and redirected primarily to patient care. Despite an ED volume increase, LOS was maintained, with fewer patients leaving against medical advice but more leaving without being seen. RVUs per hour and per patient both increased.

A NOVEL STRATEGY TO REDUCE “OFF-HOURS” DOOR TO BALLOON TIME IN ST ELEVATION MYOCARDIAL INFARCTION

BACKGROUND : The American College of Cardiology/American Heart Association guidelines for ST-elevation myocardial infarction state that an electrocardiogram (ECG) should be performed on patients with suspected acute coronary syndrome upon presentation to the emergency department (ED) within 10 minutes. OBJECTIVE : To determine how previously published clinical criteria for obtaining an ECG at ED triage perform in a population of patients receiving emergency cardiac catheterization for suspected myocardial infarction. This rule was originally derived by Graff to identify clinical criteria for obtaining an ECG at triage to rapidly identify patients with acute myocardial infarction. The Graff rule was developed in a setting where lytic therapy was the primary reperfusion strategy. A modification proposed by Glickman adds several more criteria in an effort to capture additional patients. We hypothesized that the Graff rule would identify most patients for whom the cardiac catheterization laboratory (CCL) was activated and that the Glickman rule would capture the remaining patients. METHODS : Three trained physician reviewers retrospectively applied the Graff decision rule to 430 consecutive patients from a database of emergency CCL activations by ED physicians. The Graff rule recommends that patients between the ages of 30 and 49 years received a rapid ECG if they complained of chest pain and those aged 50 years or older received a rapid ECG when they complained of chest pain, shortness of breath, palpitations, weakness, or syncope. The newly developed Glickman rule, which included nausea and vomiting in patients over the age of 80 years, was applied to the patients where the Graff rule was negative. The triage note or earliest medical contact documentation was used to determine whether the patients complaints would have resulted in a rapid ECG by the decision rule. Each case was reviewed for acute myocardial infarction as defined by high-grade stenosis on the subsequent emergent cardiac catheterization. A single data collection Microsoft Excel spreadsheet was used, and descriptive statistics were performed in Excel and Stata. RESULTS : Of the 430 CCL activations, 415 (97%; 95% confidence interval, 95%-99%) were identified by the Graff rule. Of the 12 patients who were not identified by the rule, only 2 more were identified by the Glickman criteria. Among patients with confirmed ST-elevation myocardial infarction (79% of CCL activations), the Graff rule was 98% sensitive (95% confidence interval, 96%-99%). CONCLUSIONS : The Graff ECG triage rule identified almost all patients for whom the CCL was activated. Modification of the rule as proposed by Glickman added very little to the rules sensitivity, while increasing the number of ECGs required at triage.

Use of multidetector computed tomography for the assessment of acute chest pain: a consensus statement of the North American Society of Cardiac Imaging and the European Society of Cardiac Radiology

ABSTRACT We evaluated a web-based training aimed at improving the review of fundus photography by emergency providers. 587 patients were included, 12.6% with relevant abnormalities. Emergency providers spent 31 minutes (median) training and evaluated 359 patients. Median post-test score improvement was 6 percentage points (IQR: 2–14; p = 0.06). Pre- vs. post-training, the emergency providers reviewed 45% vs. 43% of photographs; correctly identified abnormals in 67% vs. 57% of cases; and correctly identified normals in 80% vs. 84%. The Fundus photography vs. Ophthalmoscopy Trial Outcomes in the Emergency Department studies have demonstrated that emergency providers perform substantially better with fundus photography than direct ophthalmoscopy, but our web-based, in-service training did not result in further improvements at our institution.
