Critical pathways in cardiology

Observation units are dedicated areas in the hospital to deliver care to patients in observation status-those too risky to be immediately discharged following an emergency department evaluation but also clearly not in need of an inpatient admission. Observation units have been commonplace for several decades but in recent years some hospitals have begun to operate an additional observation unit with a distinct care delivery model and patient population. ⋯ Second level observation units are still relatively uncommon but are emerging as an extension of hospital-based observation services as an additional resource to cohort observation patients into a dedicated unit. These units share some similarities with traditional OUs, such as the nursing ratio of approximately 4:1 and the preponderance of chest pain pathways; however, they also differ in important ways around key metrics, such as length of stay, attending staffing coverage, and rate of subsequent inpatient admission. Additional study is needed both to fully characterize these units and their potential benefits.

To assess the clinical and electrocardiographic characteristics of patients diagnosed with ST elevation myocardial infarction (STEMI) that are associated with an increased likelihood of not undergoing percutaneous coronary intervention (PCI) after prehospital Cardiac Catheterization Laboratory activation in a regional STEMI system. ⋯ Several of the above variables are expected electrocardiogram mimics; however, the decreased rate of PCI in non-white patients highlights an area for investigation and process improvement. This may guide the development of prehospital STEMI protocols, although avoiding false positive and inappropriate activations.
