Coexisting psychiatric disorders in a New Zealand outpatient alcohol and other drug clinical population.

OBJECTIVE: To describe the extent of psychiatric disorder and mental health service utilization in a representative outpatient alcohol and other drug (AOD) treatment sample in New Zealand. METHOD: A total of 105 patients were randomly recruited from two outpatient AOD treatment services in New Zealand and completed a diagnostic interview within the first 2 months of treatment. Axis I psychiatric diagnoses were made using the computerized Composite International Diagnostic Interview (CIDI-Auto), and were supplemented by the South Oaks Gambling Scale (SOGS) and the conduct disorder and antisocial personality disorder section of the Diagnostic Interview for Genetic Studies (DIGS). RESULTS: Seventy-four per cent of the sample had a current non-substance or gambling axis I disorder, with a lifetime rate of 90%. The most commonly diagnosed of these coexisting psychiatric disorders were major depressive episode (34%), social phobia (31%) and posttraumatic stress disorder (31%). Past contact with mental health services was common, while contact at the time of baseline assessment was uncommon. CONCLUSIONS: Coexisting psychiatric disorder was the rule and not the exception in this sample. AOD patients are clearly part of the larger population of mental health patients. AOD services need to be capable of comprehensive assessment and treatment planning, which includes coexisting psychiatric disorders, and should work toward better integration with other mental health services.

Barriers to optimal care for patients with coexisting substance use and mental health disorders.

OBJECTIVE: This paper describes qualitative research that was carried out as part of a project aimed at drawing up a series of guidelines for the assessment and management for people with coexisting substance use and mental health disorders, or dual diagnosis. METHOD: A core consultation team of 14 experts with experience in the areas of both substance use and mental health in New Zealand was established to advise on the development of eight clinical scenarios. The clinical scenarios were selected to highlight a range of real life issues in the treatment of people with coexisting substance use and mental health disorders and were presented at 12 focus groups around New Zealand. The 261 participants of the focus groups were asked to comment on what was optimal management for each of the scenarios and to identify barriers to optimal care in their region. Written notes were analysed for recurring and strongly stated themes and these comprise the results of the study. RESULTS: While there was marked regional variation in treatment approaches and service structures, many of the barriers to optimal care that were identified were common to all regions. The results are considered under the headings of systems issues, clinical issues and attitudes. CONCLUSIONS: A wide variety of barriers that impede the delivery of optimal care have been identified. These range from the attitudes of individual clinicians to the structure of the systems within which they work. A system of key principles and processes for organizing treatment in a way which helps overcome these barriers is proposed.
