Screening for alcoholism.

Alcoholism is one of the largest public health problems of the nation and is a significant cofactor in such ubiquitous diseases as hypertension, developmental abnormalities, heart failure, liver failure, and many other conditions. The cost to the nation's health is immense. One strategy for reducing morbidity and cost has been to establish methods for screening in order to increase recognition rates leading to increased rates of therapeutic intervention. In this article, the rationale for two methods of alcohol screening, brief interviews and biological markers of excessive drinking, the relevant statistical issues bearing on this problem, and the current research on screening exams are reviewed and summarized. Finally, some of the newer approaches toward alcoholism screening as well as the consequences to the medical care system should alcohol screening eventuate on a large scale are briefly described.
