Hospital patients with alcohol-use disorders have higher risk of developing healthcare-associated infections, according to a study conducted by Virginia Commonwealth University in the US.

Healthcare-associated infections affect 1.7 million patients every year in the US.

Marjolein de Wit, an associate professor of medicine at Virginia Commonwealth University and first author of the study, said that the team evaluated infections such as Pneumonia and Sepsis.

Researchers used data from the Nationwide Inpatient Sample for 2007 and conducted a retrospective study of patients who developed healthcare-associated pneumonia or sepsis.

Results will be published in the July 2011 issue of Alcoholism: Clinical & Experimental Research.
