The goal of this observational study is to describe the impact measured through the Odds Ratio (OR) of different variables of clinical and biochemical alterations on the duration of the syndrome alcohol withdrawal patients measured in days of symptoms and stay; it could include any patients with a diagnosis of admission of alcohol withdrawal syndrome (AWS) who have been treated in the department of Internal Medicine for 5 years. The main question it aims to answer is: What is the relationship between the different clinical, biochemical, and hematic factors on the duration of symptoms, morbidity, and mortality in individuals with alcohol syndrome withdrawal? • If the patient has a greater number of risk factors, such as advanced age, a long and chronic history of alcohol consumption, the type of distillate consumed, as well as the deterioration of liver function and presence of leukocytosis and neutrophilia, then it is postulated that the duration of alcohol withdrawal syndrome will be longer. Clinical records will be used to describe the proportion of complications associated with alcohol withdrawal syndrome including pneumonia bronchial aspiration, seizures, need for mechanical ventilation, digestive tract hemorrhage, toxic-alcoholic hepatitis, and pancreatitis.
