Clinical diagnosis of substance use disorders in private psychiatric populations.
The clinical diagnoses of comorbid substance use and psychiatric disorders by psychiatrists in a private psychiatric inpatient setting were analyzed. Two hundred patients consecutively discharged from a private university-affiliated psychiatric service by clinical psychiatrists were examined for concomitant substance use and psychiatric disorders according to DSM-III-R criteria for Axis I and Axis II disorders. Fifty-nine patients (30%) were diagnosed with a comorbid substance use and psychiatric disorder on Axis I, supporting findings of previous studies. Comorbid diagnosis patients were more likely to be male (54%, 32) than were psychiatric only (noncomorbid diagnosis) patients (males 37%, 51). There were no differences between comorbid (dual diagnosis) and noncomorbid diagnoses in age, mean length of stay, or discharge type. Of the 59 patients with comorbid disorders, 83% had Axis I diagnoses, and 64% had Axis II diagnoses. Polysubstance use disorder was the most common dual diagnosis, cooccurring with an Axis I diagnosis in 47% of patients with an Axis II diagnosis in 45%. Psychiatrists in clinical psychiatric inpatient settings diagnose substance use disorders in rates similar to public settings despite absence of specific addiction treatment.
