Clinicians can improve their ability to estimate a patient's risk for an alcohol abuse or dependence disorder using likelihood ratios for CAGE scores.

The CAGE can effectively discriminate elderly patients with a history of drinking problems from those without such a history. The chosen cut-off score should consider the prevalence of drinking problems in the population being tested.

Our physicians appear to rely on specific patient characteristics as well as the patient's medical record to detect drinking problems in their ambulatory patients. Their reliance upon these factors may hinder their detection of drinking problems in women patients and less seriously impaired individuals.

The current study assessed whether perceived quality of life differed between alcoholics and non-alcoholics. Patients attending an urban-based hospital were screened for alcoholism using the CAGE questionnaire. Patients were recruited from an out-patient clinic setting as well as from an in-patient substance abuse unit. Quality of life scores were based on Chubon's (1987) Life Situation Survey. Results indicated that alcoholics experience a lower quality of life than their non-alcoholic counterparts regardless of setting; however, all patients reported experiencing poor life quality. The impact of alcoholism treatment programmes on patients already experiencing low quality of life is questioned.

Providing physicians with the results of the Diagnostic Interview Schedule and counseling directives resulted in short-term improvement in their rates of counseling patients with a history of dependent or nondependent but harmful drinking. Further research is necessary to determine long-term gains in rates of physician counseling and improvements in the course of these patients.
