Acute care is defined as medical services provided for illnesses that are short-term (usually less than 30 days), intense, and have a relatively severe to very severe course, requiring knowledge and expertise in the vigilant monitoring of subtle changes in the patient’s condition, as well as ability to quickly recognize and identify potential problems and conditions resulting from a previous disease. This means that when the Hospital is faced with an institutional emergency, employees in such positions may be required to remain at their work location or to report to work to protect, recover, and continue operations at Stony Brook Medicine, Stony Brook University Hospital and related facilities.
