**1. Introduction**

Ethanol is the one of the most widely abused substances in the world and is associated with substantial morbidity and mortality. Approximately 85% of adults over the age of 18 report alcohol consumption in the United States, and annually ~90,000 people die from alcohol related causes [1]. Nearly 15 million Americans meet criteria for alcohol use disorder (AUD), and it is estimated that up to 40% of hospitalized patients suffer from AUD, putting them at risk for alcohol withdrawal syndrome (AWS) and other related conditions [2]. AWS is a spectrum illness that ranges from early or mild symptoms (anxiety, headache, nausea, sleep disturbances) to later, severe, life threatening complications including seizures, dysautonomia, coma, and death [2]. It is critical for healthcare professionals to be able to recognize and understand key principles related to AWS, as well as the health conditions and complications associated with alcohol use disorder, in order to collaboratively ensure the safety and wellness of the hospitalized patient.
