Disconnect between psychiatric and addiction services: a review of patients’ attendances at Alcohol Tobacco and Other Drug Services after a psychiatric admission

Objective: To investigate the rate of attendance at Alcohol Tobacco and Other Drug Services (ATODS) for patients discharged from an acute mental health unit with a primary/secondary diagnosis of substance use disorder (SUD); and describe factors, demographics, diagnoses and service provision that relate to their attendance. Method: All inpatients between 1 November 2016 and 31 October 2017 with a diagnosis of SUD were compared for their attendance at ATODS within 30 days of discharge. Other measures included their admission data (e.g. demographics, diagnosis), and indices of their illness severity. Results: Of 1295 admissions for a total of 900 patients, 32.4% of patients had an SUD diagnosis. Only 10.3% of these patients attended ATODS. There were no significant differences by gender, age, indigenous status, illness severity or dual diagnosis intervention during their inpatient stay on attendance. Relative to the SUD-only group, individuals with any psychiatric comorbidity were three–four times less likely to attend ATODS. Conclusion: Despite the ongoing emphasis on dual diagnosis treatment, the rate of engagement with ATODS remains low. Further review is needed to determine whether enhanced information sharing or case management models may improve attendance rates.
