Syncope Evaluation in the Emergency Department Study (SEEDS): a multidisciplinary approach to syncope management.

BACKGROUND: The primary aim and central hypothesis of the study are that a designated syncope unit in the emergency department improves diagnostic yield and reduces hospital admission for patients with syncope who are at intermediate risk for an adverse cardiovascular outcome. METHODS AND RESULTS: In this prospective, randomized, single-center study, patients were randomly allocated to 2 treatment arms: syncope unit evaluation and standard care. The 2 groups were compared with chi2 test for independence of categorical variables. Wilcoxon rank sum test was used for continuous variables. Survival was estimated with the Kaplan-Meier method. One hundred three consecutive patients (53 women; mean age 64+/-17 years) entered the study. Fifty-one patients were randomized to the syncope unit. For the syncope unit and standard care patients, the presumptive diagnosis was established in 34 (67%) and 5 (10%) patients (P<0.001), respectively, hospital admission was required for 22 (43%) and 51 (98%) patients (P<0.001), and total patient-hospital days were reduced from 140 to 64. Actuarial survival was 97% and 90% (P=0.30), and survival free from recurrent syncope was 88% and 89% (P=0.72) at 2 years for the syncope unit and standard care groups, respectively. CONCLUSIONS: The novel syncope unit designed for this study significantly improved diagnostic yield in the emergency department and reduced hospital admission and total length of hospital stay without affecting recurrent syncope and all-cause mortality among intermediate-risk patients. Observations from the present study provide benchmark data for improving patient care and effectively utilizing healthcare resources.

Pulmonary embolism: an unsuspected killer.

The presentation of PE is often subtle and may mimic other diseases. Many pulmonary emboli invariably preclude diagnosis by their occult nature or by leading to rapid death from cardiopulmonary arrest. In patients who do manifest symptoms from PE, accurate diagnosis is essential. Often it is difficult to distinguish the vague symptoms of PE from other diagnoses, such as acute coronary syndrome, pneumonia, COPD, CHF,aortic dissection, myocarditis or pericarditis, pneumothorax, and musculo-skeletal or gastrointestinal causes. Regardless of the presentation, the most fundamental step in making the diagnosis of PE is first to consider it. Historical clues and risk factors should raise the clinician's suspicion.PE is an unsuspected killer with a nebulous presentation and high mortality. In all likelihood, PE will remain an elusive diagnosis despite advances in technology and a wealth of research. A high index of suspicion is required, but no amount of suspicion would eliminate all missed cases. Patients with significant underlying cardiopulmonary disease seem to be the most challenging. Patients with significant comorbidity have poor reserve and are likely to have poor outcomes, especially if the diagnosis is not made and anticoagulation is not initiated early. Controversy exists over the best diagnostic approach to PE. A battery of diagnostic studies is available, with few providing definitive answers. Studies such as CT may be helpful at some institutions but offer poor predictive value at others. Other diagnostic tests are not universally available. It is hoped that further research and improvements in current diagnostic modalities will clear some of the current confusion and controversy of this ubiquitous and deadly disease.

Evaluation of the educational utility of patient follow-up.

OBJECTIVES: To date, no studies in emergency medicine (EM) have addressed the educational value of the Residency Review Committee for Emergency Medicine's (RRC-EM) requirement for patient follow-up (FU). The authors examined whether performance of patient FU improved EM resident education. METHODS: All EM resident FU encounters from September 25, 2001, through September 24, 2002, were documented and analyzed. All EM residents at a regional tertiary referral emergency department (ED) initiated patient FU encounters by entering information regarding patients' initial ED presentations into a Web-based follow-up system (WBFUS), subsequently entered FU information, and indicated whether they thought that the specific FU encounters improved their education (yes/no). Supervising faculty members then reviewed the residents' completed FU entries. Blinded to residents' responses regarding educational utility, faculty members evaluated whether they thought the specific FU encounters were educational for the residents (yes/no). Data entered into the WBFUS were then summarized as percentages. RESULTS: Eight hundred forty-seven FU encounters were completed by 18 EM residents and 29 EM faculty. Ninety-three percent of the FU entries were deemed by at least one evaluator (resident or faculty) to have educational value. Residents found the act of performing FU educational in 81.3% of cases, whereas faculty thought 80.4% were educational for the resident. Although the residents and faculty agreed on the educational value in 75.4% of cases, the overall strength of the agreement was slight to fair (kappa statistic = 0.21). CONCLUSIONS: This study indicates that EM residents and faculty believe that the act of performing patient FU has educational value for EM residents; however, the interobserver agreement between residents and faculty was low.

Positive pressure mechanical ventilation.

There have been numerous advances in the application of positive pressure mechanical ventilation in the last two decades. As knowledge of pulmonary physiology expands, the application of modes and parameters to maximize the efficacy and minimize the complications of ventilatory support continues to advance. As the use of noninvasive ventilation becomes more widespread, its usefulness in certain clinical entities such as COPD exacerbations and acute cardiogenic pulmonary edema will become more prominent. The role of specific modes and parameters of these devices likely will be further refined to maximize outcomes.
