Since 2011, in addition to patients undergoing short-term surgery, also patients with oncological diagnoses are hospitalized in the ENT and Jaw Surgery Department at the University Hospital Basel (USB). These patients are in need of prolonged surgical treatments and resulting longer periods of abstinence from food and drink, including alcohol and other substances, increase the risk of alcohol withdrawal. For instance, in the ENT and Jaw Surgery Department, in 2011, 74 out of 910 inpatients were at risk for or already experienced an AWD and 47 of them needed permanent supervision to guarantee their safety. Bridging the period of abstinence by drinking alcohol pre- and postoperatively is a suboptimal option for these patients due to the relatively long surgical treatment. This situation called for action: based on positive experiences within the dementia-delirium-programme of USB (Hasemann & Pretto, 2006), an evidence-based approach to screen for, detect and treat AWS and / or AWD in ENT and jaw surgery patients was developed and implemented (Hasemann, 2013). Now, this new approach needs to be evaluated.
