Comparative StudyEvaluating early repeat emergency department use in patients with atrial fibrillation: a population-based analysis.
Emergency department (ED) use by patients with atrial fibrillation is high and will accelerate with the aging of the population. In patients with atrial fibrillation who are discharged from the ED, we aimed to describe their subsequent outpatient care, return ED visits, and management strategies associated with early return. ⋯ Among older patients with atrial fibrillation discharged from an ED in the province of Ontario, 9% make 1 or more repeat visits within 14 days. Reductions in repeat emergency visits by low-risk patients are associated with timely specialist follow-up care.

Randomized Controlled Trial Multicenter StudyLiberal versus restrictive transfusion thresholds for patients with symptomatic coronary artery disease.
Prior trials suggest it is safe to defer transfusion at hemoglobin levels above 7 to 8 g/dL in most patients. Patients with acute coronary syndrome may benefit from higher hemoglobin levels. ⋯ The liberal transfusion strategy was associated with a trend for fewer major cardiac events and deaths than a more restrictive strategy. These results support the feasibility of and the need for a definitive trial.

ReviewRescuing clinical trials in the United States and beyond: a call for action.
Numerous challenges-financial, regulatory, and cultural-are hindering US participation and performance in multinational clinical trials. Consequently, it is increasingly unclear how the results of these trials should be applied to American patients, practice patterns, and systems of care. Both incremental and transformative changes are needed to revitalize US participation as well as the broader clinical trial enterprise. To promote consensus around the solutions needed to address the adverse trends in clinical research, the Duke Clinical Research Institute convenedstakeholders from academia, industry, and government. article summarizes the proceedings of this meeting and addresses: (1) adverse trends in the United States and multinational clinical trials, (2) the key issues that underlie these adverse trends, and (3) potential solutions to these problems.

Multicenter Study Comparative StudyDeveloping an ST-elevation myocardial infarction system of care in Dallas County.
The American Heart Association Caruth Initiative (AHACI) is a multiyear project to increase the speed of coronary reperfusion and create an integrated system of care for patients with ST-elevation myocardial infarction (STEMI) in Dallas County, TX. The purpose of this study was to determine if the AHACI improved key performance metrics, that is, door-to-balloon (D2B) and symptom-onset-to-balloon times, for nontransfer patients with STEMI. ⋯ The AHACI has improved the system of STEMI care for one of the largest counties in the United States, and it demonstrates the benefits of integrating EMS and hospital data, implementing standardized training and protocols, and providing benchmarking data to hospitals and EMS agencies.

ReviewThe role of the emergency department in acute heart failure clinical trials--enriching patient identification and enrollment.
Nearly 800,000 of the 1 million patients hospitalized with acute heart failure (AHF) every year are initially treated by emergency physicians. Signs and symptoms are typically most severe at initial presentation, but with timely diagnostic and therapeutic management, rapid improvement can be achieved. As a direct result, emergency physicians set the tone for initial AHF management. ⋯ Moreover, because the traditional approach to AHF clinical trials has relied on cardiology-based research teams to identify patients up to 24 hours after ED presentation, patients admitted to noncardiology services are often missed, and those who are captured tend to be enrolled long after initial therapy has improved acute symptoms. This has resulted in low-enrollment heart failure clinical trials, which has been approximated at 0.41 patients per site per month. We describe the landscape of initial ED management, explain how this may confound clinical trial results, and provide a multidimensional template for successful ED/cardiology collaboration aimed at improving patient enrollment and the conduct of AHF clinical trials in the United States.
