Reduction in Drinking Associated with Improvements in Health and Quality of Life

In clinical trials for alcohol use disorder (AUD), abstinence and no heavy drinking days are currently the only end points approved by the U.S. Food and Drug Administration. However, many individuals who do not achieve these end points may still reduce their drinking to less harmful levels during treatment.

A recent study published in Alcoholism: Clinical and Experimental Research suggests that reductions in drinking risk levels could be useful end points for evaluating the effectiveness of AUD treatment for a given patient. Researchers conducted a secondary analysis of data collected from more than 1,000 individuals enrolled in the Combined Pharmacotherapies and Behavioral Interventions study funded by the National Institute on Alcohol Abuse and Alcoholism, also known as COMBINE. The COMBINE study, a clinical trial of medications and behavioral treatments for fourth edition Diagnostic and Statistical Manual of Mental Disorders alcohol dependence (as defined in the Diagnostic and Statistical Manual of Mental Disorders, fourth edition) launched in 2001 and was conducted at 11 academic sites throughout the United States.

Researchers examined the COMBINE data for associations between reductions in drinking risk levels established by the World Health Organization (WHO) and improvements in physical health and quality of life.

WHO defines four levels of drinking risk, from low risk to medium, high, and very high risk.
