Critical pathways in cardiology

Telemetry monitoring is often overused in the inpatient setting. This has led to overcrowding of telemetry beds, increased wait times in the emergency department, and inefficient allocation of hospital resources. The American College of Cardiology/American Heart Association (ACC/AHA) guidelines exist to guide appropriate utilization of cardiac monitoring. We sought to investigate the effect of the institution of an electronic ordering system (EOS) on adherence to guideline-based telemetry use. ⋯ The institution of an EOS significantly improved compliance with ACC/AHA guidelines for cardiac monitoring at the time of admission. However, compliance worsened after the initial 48 hours, which may have been due to the ease of online reordering with our EOS. Clinically significant events were only observed in patients who met criteria for monitoring. EOS can be a useful tool to improve adherence to guideline-based utilization of hospital resources.

Epidemiological studies have demonstrated racial disparities in the workup of emergency department patients with chest pain and the referral of admitted patients for intervention. However, little is known about possible disparities in stress test utilization in low-risk chest pain patients admitted to emergency department chest pain units. ⋯ Our study confirms racial disparities in the utilization of stress testing in the chest pain unit. Further investigation is needed to identify specific provider or patient-level factors that may contribute to this disparity.

: 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. ⋯ : 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 rule's sensitivity, while increasing the number of ECGs required at triage.

The latest American College of Cardiology/American Heart Association guidelines recommend primary percutaneous coronary intervention (PCI) in acute ST-elevation myocardial infarction (STEMI) patients within 90 minutes from presentation to the emergency room. For interhospital transfers, the most recent PCI guidelines recommend first medical contact-to-device times ≤120 minutes. Although PCI-capable hospitals have improved door-to-balloon times, many patients present to non-PCI-capable facilities and have been excluded from national quality measures. ⋯ In our single-center experience, 22 scene STEMI patients were diagnosed and appropriately triaged by EMS to our center for primary PCI. Our data show feasibility of an EMS-activated STEMI network over long distances with good reperfusion times.

The strategy of prehospital activation by the emergency medical system (EMS) in patients with ST-elevation myocardial infarction (STEMI) has been poorly adopted among the US hospitals that currently offer 24/7 primary percutaneous coronary intervention. In this study, we report a single center experience after the implementation of this strategy. From 2008 to 2011, we identified a total 188 STEMI patients (age 65 ± 15 years) presenting via EMS for primary percutaneous coronary intervention. ⋯ ED 39 ± 14.6%; P = 0.004). Differences in DTB time and left ventricular ejection fraction remained significant after adjusting for differences in baseline characteristics. In conclusion, the prehospital activation strategy is largely effective and should be systematically adopted in the treatment scheme of STEMI patients to lower mechanical reperfusion times and reduce the potential for untoward clinical outcomes.
