Underdiagnosis of alcohol dependence in psychiatric inpatients.

Alcoholism is prevalent among psychiatric inpatients, and accurately diagnosing alcohol problems is a critical step in treatment planning. The authors diagnosed alcohol dependence in 35 psychiatric inpatients by blind review of interview protocols and hospital records. They then examined the frequency with which admitting and attending clinicians diagnosed alcohol abuse and dependence in these patients. Alcoholism was underdiagnosed; 24% of the clinicians' diagnoses included no alcoholism diagnosis, 39% were alcohol abuse, and only 37% were alcohol dependence. Underdiagnosis was strongly associated with the presence of a comorbid psychosis, as well as with patients' denial of alcoholism and with less severe alcoholism. The authors discuss the patient and clinician variables which may contribute to underdiagnosing alcoholism and recommend educational and administrative measures to improve clinicians' diagnostic sensitivity.
