Abstract:

Objective

To investigate whether alcohol dependence is associated with the prognosis of critically ill patients.

Methods

Critically ill patients were selected from a publicly accessible foreign critical care electronic database, and alcohol dependence was determined based on diagnoses related to alcohol abuse. Logistic regression and Cox regression models were used to adjust potential confounding factors and analyze the associations between alcohol dependence and prognosis of the critically ill patients including hospital mortality, 28-day mortality, and 90-day mortality after hospital admission.

Results

A total of 29 487 critically ill patients were included in the study. All patients were transferred to intensive care units within 24 h after hospital admission. The average age of the study population was (63.93±17.09) years, and 7.77% (2292/29 487) of them were alcohol-dependent. After adjusting for potential confounders mainly including age, sex, comorbidities, and disease severity scores when admitted to intensive care unit, alcohol dependence was found to be a risk factor for hospital mortality (odds ratio=1.28, 95% confidence interval: 1.05-1.57, P=0.0147), and 28-day mortality after admission (risk ratio=1.25, 95% confidence interval: 1.06-1.48, P=0.0092), but there was no statistically significant association with 90-day mortality after admission (risk ratio=1.07, 95% confidence interval: 0.93-1.23, P=0.3239).

Conclusion

Comorbid alcohol dependence might be an independent risk factor for poor short-term prognosis in critically ill patients.
