Evaluate the prevalence of the alcohol delirium, assess the presence of the comorbidities, identify the factors affecting duration of hospitalization in patients with alcohol delirium at DRS narcology section. Participants: the study included both sex patients who joined the DRS narcology section during the period from 1 June to 30 September 2020 with a diagnosis of Alcohol delirium. Data was analyzed with the IBM SPSS Statistics 26.0. The differences between groups were assessed by Mann-Whitney U test. The association between factors and duration of treatment was evaluated using Chi-squared test (Fisher’s Exact Test). The statistical significance level in this study was accepted as 0,05. Alcohol delirium occurred in 46 patients, 43 men (93,5%), 3 women (6,5%). The prevalence of alcohol delirium was 3,38% (46 from 1363). Dementia was found in 4 patients (8,7%), organic personality disorder - 5 (10,9%), epilepsy – 8 (17,4%), polyneuropathy – 5 (10,9%), head injury in the anamnesis – 10 (21,7%), encephalopathy – 5 (10,9%), pancreatitis – 3 (6,5%), pneumonia – 4 (8,7%), metroragia – 1 (2,2%), toxic hepatitis – 1 (2,2%). The distribution of PLT, ALAT, CRO values in both groups differed statistically significantly, Mann-Whitney U test, p < 0,05. The association between the presence of dementia, epilepsy, pancreatitis, pneumonia, polyneuropathy, means of subsistence, disability pension and the duration of treatment was statistically significant, Fisher’s Exact Test, p < 0.05. The duration of treatment in patients with alcohol delirium is found to be associated with some comorbidities and social factors such as income. Most likely patients with dementia, epilepsy, polyneuropathy, pancreatitis, pneumonia and patients who have only disability pension are treated longer.
