Lifetime psychiatric hospital diagnoses among 8,412 Danish men registered in an outpatient alcohol clinic
Abstract
Abstract Objective To describe the prevalence of lifetime psychiatric hospital diagnoses among men registered in an outpatient alcohol clinic and compare the prevalence with matched controls. To assess temporality of alcohol use disorder (AUD) diagnoses and another psychiatric hospital diagnosis and examine the prevalence of lifetime psychiatric hospital diagnoses according to this temporal order. Methods The study included 8,412 Danish men registered in an outpatient alcohol clinic, and 8,412 unregistered controls from the Danish Conscription Database matched on birth date, lifespan, intelligence and draft board district. Information on first outpatient AUD treatment was retrieved from the Copenhagen Alcohol Cohort. Information on lifetime psychiatric hospital diagnoses was retrieved from national Danish psychiatric registers and based on the International Classification of Diseases the 8th and 10th Revisions. Prevalence estimates of lifetime psychiatric hospital diagnoses were compared with odds ratios (OR) between men registered in an outpatient alcohol clinic and the control population. Results Among men registered in an outpatient alcohol clinic, 66.6% had a lifetime psychiatric hospital diagnosis. In total, 8.6% had neuroses and anxiety disorders, while 25.3% had personality disorders. The OR of a lifetime psychiatric hospital diagnosis was 9.77 (95%CI: 8.87–10.75) when comparing men registered in an outpatient alcohol clinic with the control population. Among men with a lifetime psychiatric hospital diagnosis, 42.8% was registered with another psychiatric hospital diagnosis before registration with an AUD diagnosis. Conclusion Among men with a lifetime psychiatric hospital diagnosis, AUD is rarely diagnosed without psychiatric comorbidity at first‐time admissions to psychiatric hospital departments.
