Short stay units hold patients up to 72 hours and, in some facilities, are known as clinical decision units. The three main functions identified in short stay units are to provide observation, to involve specialists to make assessments and diagnoses, and to provide short-term, high-level management of the patient. Some facilities identify a perioperative unit as a short-stay unit, but most are affiliated with emergency departments. Patients in short-stay units must have the ability to meet basic self-care needs, and there must be a likelihood of reasonable pain control. A surgical observation unit is considered a specialized unit designed to receive postoperative and post-procedural patients with stays ranging from one to 24 hours. While consolidated units are not the norm, they are on the rise around the country. Approximately 30% of hospitals have an observation unit of some kind. Data suggests that dedicated units reduce the length of stay for observation patients and free up beds elsewhere. Still, the “right” model depends on patient volume, capacity, and culture of each organization (Dias, 2016).
