Brief summary
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.
Detailed 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.
Interventions
BEHAVIORALAlcohol Used Disorders Identification Test (AUDIT C)
The Audit-C questionnaire is a three item alcohol screen that can help identify persons who are hazardous drinkers or have active alcohol abuse disorders (including alcohol abuse or dependence). The AUDIT-C is a modified version of the 10 question AUDIT instrument. Score from 0 to 12. Each Audit-C question has a 5 answer choice, allotted points are from 0 to 4 points. In men, a score of 4 is considered as positive, optimal for identifying hazardous users or active alcohol abuse disorders. The same for 3 points in women.
PROCEDURECarbohydrate deficient transferrin
Blood sample to collect carbohydrate deficient transferrin (CDT) only if the Alcohol Used Disorders Identification Test (AUDIT C) reports at least 1 point.
PROCEDUREGamma glutamyl transpeptidase
Results of Gamma glutamyl transpeptidase (GGT) performed as routine practice collected only if the Alcohol Used Disorders Identification Test (AUDIT C) reaches at least 1 point.
PROCEDUREMean Corpuscular Volume
Results of Mean Corpuscular Volume (MCV) performed as routine practice collected only if the Alcohol Used Disorders Identification Test (AUDIT C) reports at least 1 point.
