Interdisciplinary teamwork and leadership: issues for psychiatrists.

OBJECTIVE: To review the constructs and applications of interdisciplinary teams in mental health services, with a particular view to ascertaining the most effective types of teams and their leadership. METHOD: Some of the most challenging questions from a psychiatrist's viewpoint regarding the functions of interdisciplinary teams in the mental health service are addressed. RESULTS: The effectiveness of the interdisciplinary team in mental health services is supported by an extensive literature that is much more qualitative and descriptive than quantitative and empirically rigorous, except as part of packages of variables subjected to randomized controlled trials. CONCLUSION: Effective interdisciplinary teamwork in mental health services involves both retaining differentiated disciplinary roles and developing shared core tasks. It requires sound leadership, effective team management, clinical supervision and explicit mechanisms for resolving role conflicts and ensuring safe practices. No one profession should hold a monopoly on leadership.

Australia needs a mental health commission.

OBJECTIVES: The present paper aims to: (i) describe how the Mental Health Commission in New Zealand works and has contributed to the substantial enhancement of mental health resources and services; (ii) determine whether mental health reform policies will ever be implemented properly without an independent monitor with official influence at the highest levels of government; and (iii) demonstrate how variants on this model work in other Western countries and how it can be adapted to the Federated system in Australia. CONCLUSIONS: It is recommended that the Australian National Mental Health Plan 2003-2008 should be complemented by a long-standing national mental health commission (or similarly constituted body), which is also able to report independently from and to the government, with direct access to the Prime Minister, Premiers and Australian Health Ministers. Its aims would be to monitor service effectiveness and identify gaps in service provision, training and performance of the work force, management and government. It would be informed by consumer, carer and provider experience, and by reviews of evidence-based research regarding health needs and cost-effective services. It should accurately cost such service gaps, and advise government on a strategy for implementing them. It could also promote and advise formally on enhancing community awareness, decreasing stigma and discrimination and improving workforce recruitment and retention.

Clinical outcome of an early psychosis intervention program: evaluation in a real-world context.

OBJECTIVE: To examine whether staff training and service restructuring to provide specialized early psychosis services results in improved clinical outcomes for young people with first-episode psychosis. METHOD: Staff attended workshops on the treatment of early psychosis throughout 1997-2000 and specialized early psychosis teams began operating between 1998 and 2000 following service restructure. There was no additional funding provided for clinical services, but through the restructure, there was a shift in resources. During this period a comprehensive package including the Brief Psychiatric Rating Scale, Scale for the Assessment of Negative Symptoms and the Health of the Nation Outcome Scale was introduced for clinicians to assess patients at intake, 3 months and 12 months into treatment. Symptom scores of patients treated earlier in the project are compared with those patients treated later, after more training and service developments had occurred. RESULTS: Ninety-four of 215 potential first-episode patients consented to take part in the project. They provided data variously at intake, 3 months and 12 months into treatment. Regardless of the year of treatment, significant improvement in psychiatric symptomatology was found over the three assessment periods. Individuals who entered the service in the latter phase of the project experienced fewer negative symptoms (after 12 months of treatment) compared with patients who entered the service in the early phase of the project. CONCLUSIONS: Improvements in both pharmacological and possibly psychosocial treatment may have led to a greater improvement in negative symptoms. Benefits and limitations of conducting research in a "real-world" context are discussed.

Changes in early psychosis service provision: a file audit.

OBJECTIVE: To measure change in services provided to young people with first-episode psychosis following the introduction of specialized early psychosis teams and staff training. METHOD: A standardized tool was developed to audit services provided to young people with first-episode psychosis. The tool initially comprised 27 clinical indicators measuring aspects of optimal care derived from the Australian clinical guidelines for early psychosis. The first 12 months of treatment, as documented in the case records, were audited for all young people receiving their first treatment for psychosis during a 6-month period prior to the introduction of these service developments (n = 47). These subjects were compared with those who received treatment after the implementation of service development strategies (n = 70). A comparison was also made within the second group, between those receiving some treatment from a specialized early psychosis team and those being exclusively treated by other services. RESULTS: Inter-rater reliability was achieved for 24 of the 27 indicators. Improvements were found on 10 indicators which measured psychosocial interventions, prescribing practices, family interventions and continuity of care. There was no significant deterioration on any of the indicators. Clients who attended early psychosis teams were significantly more likely to receive psychoeducation. CONCLUSIONS: The services increased their provision of "guideline concordant" care for early psychosis. The audit proved useful to monitor performance, to demonstrate improvements in care and to identify those areas of service provision and documentation in need of improvement.

Quantification of insulin-mediated glucose disposal in HIV-infected individuals: comparison of patients treated and untreated with protease inhibitors.

To describe the distribution of insulin sensitivity and glucose tolerance in HIV-infected patients, the authors measured insulin-mediated glucose disposal (IMGD) in 51 subjects (24 protease inhibitor (PI)-treated subjects and 27 non-PI-treated subjects). IMGD was determined by measuring the steady-state plasma glucose (SSPG) concentration during the last 30 minutes of a 180-minute intravenous infusion of octreotide, glucose, and insulin. In addition, oral glucose tolerance testing was performed. SSPG concentrations varied six-fold in both groups, and the mean values +/- SEM did not differ between PI-treated and non-PI-treated groups (8.7 +/- 0.9 vs. 8.0 +/- 0.7 mmol/L, respectively). The mean fasting plasma glucose concentration +/- SEM was higher in the PI-treated subjects than in the non-PI-treated subjects (5.44 +/- 0.11 vs. 5.05 +/- 0.11 mmol/L, respectively; p =.01), whereas fasting plasma insulin concentrations did not differ. PI-treated patients also had significantly higher plasma glucose (p =.001) and insulin (p =.03) responses to the oral glucose challenge. However, whereas the incremental plasma glucose response during the first 30 minutes was significantly higher in PI-treated patients, the incremental insulin response in the two groups was identical. In conclusion, insulin sensitivity varies widely in HIV-infected patients irrespective of PI treatment, and the adverse effect of PIs on insulin sensitivity is likely to be of modest magnitude. Finally, PI treatment may have an inhibitory effect on insulin secretion.

Methods for quantifying insulin resistance in human immunodeficiency virus-positive patients.

Various indirect indices have been used in human immunodeficiency virus (HIV)-infected individuals to assess insulin resistance, but the validity of these measures has not been rigorously assessed by comparison with physiologic methods of quantifying insulin-mediated glucose uptake (IMGU). We directly measured IMGU in 50 nondiabetic HIV-positive subjects by determining the steady-state plasma glucose (SSPG) concentration in response to a 3-hour continuous infusion of insulin, glucose, and somatostatin. Because steady-state plasma insulin concentrations were similar (approximately 60 microU/mL) in all subjects, the SSPG concentrations provided direct assessments of insulin action. Relationships between SSPG levels and various surrogate measures of IMGU derived from the 75-g oral glucose tolerance test (OGTT) were determined. The indirect measure of IMGU most closely related to SSPG concentrations was the total integrated insulin response to a 75-g glucose load (r=0.78, P<.01), accounting for approximately two thirds of the variability in SSPG (r2=0.61). Other indirect measures of IMGU, including the homeostasis assessment for insulin resistance (HOMA-IR), were also significantly related to SSPG values, but had lower magnitudes of correlation (r=0.43 to 0.61), thereby possessing limited ability to predict SSPG variability (r2=0.18 to 0.37). In conclusion, indirect measures of IMGU need to be applied with caution when evaluating insulin action in HIV-infected patients.

Deinstitutionalization for long-term mental illness: a 6-year evaluation.

OBJECTIVE: Forty-seven patients with long-term mental illness were transferred to the community following the closure of a psychiatric hospital in Sydney. This 6-year evaluation is an extension of a detailed clinical, ethnographic and economic study of the initial 2-years of community transition. METHOD: Quantitative evaluation was conducted using the Brief Psychiatric Rating Scale, Life Skills Profile, Social Behaviour Scale, Montgomery Asberg Depression Rating Scale and Quality Of Life measures. Assessments were completed prior to discharge and at two- and 6-year intervals following community transfer. Repeated measures analysis was utilized to determine changes in outcome variables over time. The residents' perception of 6-years of community living was explored in qualitative semistructured interviews. Details of accommodation, level of care, readmissions, incidents and medication were also documented. RESULTS: During the 6 years following community relocation a total of seven residents returned to hospital for long-term care, three residents died from medical causes and one resident required detention in a corrective services facility. The 36 residents who remained in the community at the 6-year follow-up no longer required intensive 24-h supervision. Living semi-independently, 23 residents resided in two to three person accommodation with either daily or weekly case manager visits. Clinically, community residents remained stable over the 6 years without significant changes in psychiatric symptoms, depression, living skills or social behaviour problems. Clinical stability was achieved with significant reduction in medication levels over the 6 years. Community-based residents continued to experience improved quality of life and reported their marked preference for living in the community. CONCLUSION: The residents maintained community tenure with significant improvement in quality of life and a reduction in medication, supported by a mental health system with adequate community resources. Issues regarding continuing rehabilitation and social integration need to be addressed. Further deinstitutionalization will require 24-h supervision for most initially and for some on a continuing basis. An ageing population will require specific age related medical and psychiatric services.

Medical student knowledge and attitudes regarding ECT prior to and after viewing ECT scenes from movies.

We surveyed samples of medical students in the United Kingdom (U.K.) and Australia, prior to their psychiatry placement, to ascertain views about electroconvulsive therapy (ECT) and the effect on those views of watching ECT scenes in movies. A 26-item questionnaire was constructed by the authors and administered to the students. At set times during the questionnaire, students were asked to view five movie clips showing, or making reference to, ECT. The clips were from Return to Oz, The Hudsucker Proxy, Ordinary People, One Flew Over the Cuckoo's Nest, and Beverly Hillbillies. Ninety-four students participated in the study. Levels of knowledge about the indications, side effects, and mode of administration were poor, and attitudes were generally negative. Viewing the ECT scenes influenced attitudes toward the treatment; after viewing, one-third of the students decreased their support for ECT, and the proportion of students who would dissuade a family member or friend from having ECT rose from less than 10% to almost 25%.
