Alcohol abuse and dependence disorders are common in the 10% of hospitalised patients who need admission to the intensive care unit (ICU), but these disorders are often undiagnosed. The systemic effects from the excessive use of alcohol increase susceptibility to, or directly cause various important disorders in the critically ill. Early recognition of alcohol abuse and dependence is necessary and should prompt consideration of several alcohol-specific diagnoses that have important prognostic and therapeutic implications for these patients. We discuss the use of screening tests to improve the identification of alcohol abuse and dependence disorders, the epidemiology and pathogenesis of important alcohol-related disorders, differences in the presentation of several common alcohol-related diagnoses in the ICU, and important alcohol-specific therapies.

Generalised anxiety disorder is a persistent and common disorder, in which the patient has unfocused worry and anxiety that is not connected to recent stressful events, although it can be aggravated by certain situations. This disorder is twice as common in women than it is in men. ⋯ The symptoms overlap greatly with those of other common mental disorders and we could regard the disorder as part of a spectrum of mood and related disorders rather than an independent disorder. Generalised anxiety disorder has a relapsing course, and intervention rarely results in complete resolution of symptoms, but in the short term and medium term, effective treatments include psychological therapies, such as cognitive behavioural therapy; self-help approaches based on cognitive behavioural therapy principles; and pharmacological treatments, mainly selective serotonin reuptake inhibitors.
