Objective: To review psychiatrists’ attitudes and actual practice on the use of typical and atypical antipsychotics in the elderly. Methods: Audit data were collected from 18-old-age psychiatry units across Australia. The attitudes of old age psychiatrists and their perceptions of the efficacy, tolerability and clinical usefulness of antipsychotics were examined. Results: The medications used for 321 patients were audited, and the attitudes of the 57 prescribing doctors were assessed. All available atypicals were prescribed and reported as more efficacious and clinically useful than typicals. Adverse events perceived by doctors as an obstacle to prescribing were more frequent than reported adverse event rates in product information. All diagnostic groups improved. Off-label use comprised almost 22% in this sample. Conclusions: Adverse events are impediments to prescribing, more so with typical than atypical antipsychotics. All available atypicals were used and appeared effective in this elderly population. [ABSTRACT FROM AUTHOR]

Objectives: There exists a substantial and growing body of evidence suggesting that antipsychotic medications are efficacious in the treatment of many non-psychotic psychiatric disorders. Although indications for the use of antipsychotics (particularly the atypicals) remain relatively narrow in Australia, psychiatrists seem to be using them for an expanding range of disorders in a variety of clinical settings. This has raised issues of cost-effectiveness and methods of funding of these medications. The present study aimed to quantify and describe the patterns of prescribing of antipsychotic medications in a large private psychiatric hospital. Another aim was to compare the findings with other published evidence, and consider the implications of antipsychotic use for current clinical practice in Australia.Methods: A retrospective review of the medical records of 100 consecutive patients admitted to a private psychiatric hospital was conducted. The data collected included demographic details, major psychiatric diagnoses, all medications prescribed during the admission and their doses and, in the case of antipsychotics, the target symptoms/conditions for which they were prescribed.Results: Fifty-nine per cent of inpatients received at least one dose of an antipsychotic during their admission. While all patients with psychotic illnesses were treated with antipsychotics, 57% of patients with primary mood disorders and 40% of patients with a primary anxiety disorder also received an antipsychotic. The most common indications for use of antipsychotics included the treatment of psychotic symptoms, augmentation of antidepressants, relief of anxiety symptoms and lessening of agitation, and control of difficult behaviours (including self-harm and aggression) associated with personality disorders. The most frequently used antipsychotic was olanzapine (22%), followed by chlorpromazine (20%), and quetiapine (14%). Eleven per cent of patients received a combination of two antipsychotics.Conclusions: Antipsychotic medications were widely used in a private psychiatric inpatient setting for the treatment of non-psychotic disorders. This finding parallels those from other Australian studies of psychotropic prescribing patterns. The issues of clinical utility, cost-effectiveness and benefits of funding of these medications for such wider indications require further study and evaluation. [ABSTRACT FROM AUTHOR]

Objective: In Australia, mental health services are delivered by a complex web of public- and private-sector providers. There is a growing recognition that linkages between these groups are not optimal, and a concern that this may lead to poor outcomes. This paper illustrates a conceptual framework for developing, implementing and evaluating programmes concerned with linkages. Method: Drawing on theoretical and practical literature, this paper identifies different levels of integration, issues in evaluating programmes to address poor linkages, and features of useful evaluations. Within this context, it describes the method by which the Public and Private Partnerships in Mental Health Project (Partnership Project) is being evaluated. Conducted by St Vincent’s Mental Health Service and The Melbourne Clinic, this is one of several Demonstration Projects in Integrated Mental Health Care funded under the National Mental Health Strategy. Results: Collaboration is hard to conceptualize and collaborative programmes usually have many players and components, and tend to operate within already-complex systems. This creates difficulties for evaluation, in terms of what to measure, how to measure it, and how to interpret findings. In spite of these difficulties, the illustrative example demonstrates a model for evaluating collaborative programmes that is currently working well because it is strongly conceptualized, descriptive, comparative, constructively sceptical, positioned from the bottom up, and collaborative. Conclusions: This model, or aspects of it, could be extended to the evaluation of other mental health programmes and services that have collaborative elements. [ABSTRACT FROM AUTHOR]

The aim of this pilot study was to examine the relationship between clinical response, adverse effects, sertraline (SERT) plasma concentrations and the genetic polymorphism of the serotonin transporter gene-linked polymorphic region (5HTTLPR) in 2 ethnic patient groups. The study involved 45 patients in a clinical trial who received a fixed dose regimen of 50 mg SERT for one week, then a variable-dose regimen for a further 6 weeks for major depressive disorder. At weeks 1 and 6, the following assessments were completed: Hamilton Depression Rating Scale (HDRS), Clinical Global Impression (CGI), drug adverse reaction scale and measurement of plasma SERT levels. Genomic analysis for the long and short allele variants of the 5HTTLPR polymorphism was also carried out. Caucasian subjects had a higher rate of l/l genotype while Chinese subjects had higher frequencies of l/s and s/s genotypes. Comparison of the subjects with the 5HTTLPR s/s genotype and those with the l/l and l/s genotypes found no significant differences in the HDRS scores, CGI scores, response rates, adverse effects and SERT plasma concentrations at week 6.

This prospective 6-week study examined the differences in dosage and steady state plasma concentrations of sertraline in Chinese versus Caucasian depressed patients. Two groups of Chinese patients from different geographical sites and a group of Caucasian patients were evaluated with clinical measures during an initial dose of 50 mg/day, with subsequent doses adjusted clinically. The results of 17 Australian Chinese (ACHI), 13 Malaysian Chinese (MCHI) and 15 Australian Caucasians (AC) were analysed. Despite controlling for weight, the AC subjects received a significantly higher dose than both the ACHI (P = 0.002) and the MCHI groups (P = 0.012). However, the mean sertraline concentration to dose ratios at weeks 1 and 6 were not significantly different between the three groups. Sertraline was effective and well tolerated in both ethnic groups with few adverse events. Although there was a lack of difference between groups in the pharmacokinetic results, Chinese depressed patients appeared to require lower dosages with consequently lower plasma concentrations of sertraline compared to Caucasian patients to achieve clinical efficacy. Further studies of the dosages, kinetics and adverse effects of selective serotonin reuptake inhibitors linked with genotyping are necessary.

Objectives: We describe the evaluation of the Partnership Project, which was designed to improve linkages between public and private sector mental health services. We consider the Project's key elements: a Linkage Unit, designed to improve collaborative arrangements for consumers and promote systems-level and cultural change; and the expansion of private psychiatrists' roles to include supervision and training, case conferencing and secondary consultation. The evaluation aimed to describe the impacts and outcomes of these elements., Method: The evaluation used de-identified data from the Linkage Unit database, the Project's billing system, and the Health Insurance Commission (HIC). It drew on consultations with key stakeholders (semistructured interviews with 36 key informants, and information from a forum attended by over 40 carers and a meeting of five public sector and three private sector psychiatrists) and a series of case studies., Results: The Linkage Unit facilitated 224 episodes of collaborative care, many of which had positive outcomes for providers, consumers and carers. It had a significant impact at a systems level, raising consciousness about collaboration and influencing procedural changes. Thirty-two private psychiatrists consented to undertaking expanded roles, and the Project was billed $78 032 accordingly. Supervision and training were most common, involving 16 psychiatrists and accounting for approximately 80% of the total hours and cost. Commonwealth expenditure on private psychiatrists' participation in the expanded roles was not associated with a reduction in benefits paid by the HIC. Key informants were generally positive about the expanded roles., Conclusions: The Project represented a considered, innovative approach to dealing with poor collaboration between the public mental health sector, private psychiatrists and GPs. The Linkage Unit achieved significant systems-level and cultural change, which has the potential to be sustained. Expanded roles for private psychiatrists, particularly supervision and training, may improve collaboration, and warrant further exploration in terms of costs and benefits.
