Comparative Study
Wireless cardiac event alert monitoring is feasible and effective in the emergency department and adjacent waiting areas.
The need for vigilance for unexpected clinical deterioration in the emergency department (ED) waiting area and in unmonitored treatment areas of the ED continues to increase. We sought to determine in an observational study the feasibility and relative false-alarm burden of, and satisfaction with, a novel wireless automated clinician alert device for cardiac rate and rhythm derangements in a teaching hospital ED. Patients presenting with a variety of complaints who after ED triage were not placed on conventional telemetric monitoring (by standard triage policy) were considered for inclusion. ⋯ There were 10 false-positive asystole or ventricular fibrillation alarms in 4 patients (1.3%), all of which were readily attributable to nonclinical origins, such as poor lead adherence. There was excellent satisfaction with the device from both patients and clinical personnel. Wireless cardiac event monitoring is feasible in the ED, and improves the throughput of ED patients with worsening vital signs, and may improve overall patient safety, without an onerous burden of nonproductive alarms.

Improvements in time to reperfusion: do women have an advantage?
Several studies demonstrate that women have greater delays in primary percutaneous coronary intervention (PCI). To improve care for women, the Women's Heart Advantage at Yale-New Haven Hospital (YNHH) developed patient- and physician-level interventions to improve knowledge about chest pain syndromes to promote early presentation, diagnosis, and timely management of ST-elevation myocardial infarction (STEMI) in women presenting to the emergency department. Specifically, we analyzed chart-abstracted data from all patients undergoing PCI for STEMI at YNHH from January 2004 to July 2007 and assessed quality of care for STEMI and trends in time to reperfusion. ⋯ In this single-site study of men and women undergoing primary PCI at a large, urban teaching hospital, where ongoing interventions to increase both patient and physician awareness regarding heart disease in women were initiated, time to reperfusion for women improved to a greater degree than in men. These results are encouraging, showing that significant improvements can be made over a relatively short time frame. It is hoped these reductions in time to reperfusion are associated with improved outcomes; however, further studies are needed to verify this potential benefit.

Evidence-based guidelines call for advanced and definitive therapy for patients with non-ST-elevation myocardial infarction (NSTEMI). It is not known whether these guidelines are follow more diligently when patients arrive in the ED during regular hours, during which hospital resources including cardiology consultation may be more readily available. To determine whether patients with NSTEMI who present to the ED outside of usual hours have prolonged times to advanced and definitive therapy and poorer short-term outcomes. ⋯ Despite these differences, in-hospital outcomes were similar. Time of patient presentation has a modest impact on the timeliness of intervention in NSTEMI but was not associated with lower mortality. Although intensity of medical management was similar between groups, it was generally lower than current guidelines recommend, indicating potential for improvement in NSTEMI outcomes, regardless of time of presentation.

Physician documentation of nonspecific EKG changes predicts hospital admission among observation unit chest pain patients.
Our emergency department (ED) observation unit specifically excludes patients with "significant" electrocardiogram (EKG) findings, but patients may be admitted with "nonspecific" EKG findings. We evaluated whether physician documentation of nonspecific findings predicted eventual admission to an inpatient unit from the observation unit. We reviewed the charts of all chest pain patients admitted to our ED observation unit over a 14-month period. ⋯ Patients with documented nonspecific EKG changes also had higher rates of positive stress testing (17.5% vs. 10.5%, P = 0.103) and stent placement (5.1% vs. 3.3%, P = 0.309), although these were not statistically significant. Patients with documented nonspecific EKG findings were admitted to an inpatient unit from the observation unit at higher rates than those without these findings. Physicians may wish to use the ED EKG more effectively in screening patients for admission to the ED observation unit.

Although treatment guidelines from the American College of Cardiology (ACC) and the American Heart Association (AHA) have been published and widely accepted, barriers to the optimal management of patients with acute coronary syndromes (ACS) still exist. Adherence to guidelines has been correlated with improvements in patient outcomes in ACS, including reduced mortality, yet data demonstrate that 25% of opportunities to provide guideline-recommended care are missed. This article describes a performance improvement (PI) initiative designed to address gaps in process-related ACS care and improve patient outcomes. ⋯ In this ACS PI initiative, physicians will assess their practice using performance measures defined by the 2007 ACC/AHA ST-segment elevation myocardial infarction and unstable angina or non-ST-segment elevation myocardial infarction guideline updates within 3 general benchmark areas: (1) patient risk assessment, (2) initial pharmacologic management, and (3) time-to-treatment (ie, "door-to-needle," "door-to-balloon," and "door-in-door-out" times). After completing a self-assessment and identifying 1 or more areas of improvement, participants can complete educational interventions and access benchmark-specific tools that provide guidance on improving adherence with the ACC/AHA guidelines. This PI initiative supplements other ongoing quality improvement initiatives in ACS, but is unique in that it is the first to use individual physician self-assessment, benchmark-focused continuing medical education, and self-developed PI plans to improve process-related ACS care.
