About

Alcohol misuse affects 5 million people in France. Even though the elderly are also concerned by this pathology, there is not much information about chronic alcohol misuse of this population in particular.

Biological markers like gamma-glutamyltranspeptidase (GGT), mean corpuscular volume (MCV) and carbohydrate deficient transferrin (CDT) are usually used to detect alcohol abuse. As a biological marker of alcohol misuse, the specificity of the CDT is known to be superior to the GGT as well.

However, when it comes to the elderly, alcoholism diagnosis tools are based on research of younger populations.

This study aims to evaluate the benefit of the CDT to detect chronic alcohol use in the elderly.

Full description

Problematic alcohol misuse is frequent but tends to decrease with age. According to the French Alcohology Society, 10% of the adult population is alcohol abstinent and after 65 years old, they are 40% to abstain from alcohol.

On the other hand, the French Alcohology Society also reports that a regular or daily alcohol consumption for older people increases the risk of dependence on alcohol.

For the elderly, biological disorders can be related to polymedication or other conditions related to the aging process, making it difficult to diagnose alcoholism for aged people.

For the study, the three-item Alcohol Use Disorders Identification Test (AUDIT-C) will be submitted to :

• every patient admitted in the Hospital of Mulhouse (France) for at least a day in the Geriatrics Department
• every patient entering the General Practitioner Support Association of Alsace, France (translated in French as the "RAG").

When the score of the AUDIT-C reaches at least 1 point, the study will collect results of the GGT and MCV performed as routine practice and add the CDT in the blood tests.

Alcohol Used Disorders Identification Test (AUDIT C)

Other group

Description:

Submission of Audit-C questionnaire to all the patients of the study. When the result to the AUDIT-C questionnaire reaches at least 1 point, the analysis of the Carbohydrate deficient transferrin (CDT) is performed within 3 days after the beginning of the study. Results of Gamma glutamyl transpeptidase (GGT) and Mean Corpuscular Volume (MCV) performed as routine practice collected at the same time as the CDT analysis.

Treatment:

Behavioral: Alcohol Used Disorders Identification Test (AUDIT C)

Procedure: Mean Corpuscular Volume

Procedure: Gamma glutamyl transpeptidase

Procedure: Carbohydrate deficient transferrin
