ReviewMaintenance therapies in bipolar disorder: focus on randomized controlled trials.
Lithium remains the cornerstone of maintenance therapy for bipolar disorder despite growing use of other agents, including divalproex, lamotrigine, carbamazepine and the atypical antipsychotics. Lithium has the largest body of data to support its continued use as a prophylactic agent; however, most of this data comes from early studies that did not use contemporary analytic methods. Alternatives to lithium are needed because of the relatively high rate of non-response to lithium monotherapy and the drug's frequent side-effects. This article reviews available data with an emphasis on double-blind, placebo-controlled studies that examine the efficacy of lithium and other putative mood stabilizers: carbamazepine, divalproex, lamotrigine and olanzapine. ⋯ Any monotherapy for use as a maintenance therapy of bipolar disorder appears to be inadequate for long-term use in the management of the majority of patients with bipolar disorder. Combination therapy has become the standard of care in the treatment of bipolar disorder and particularly in patients with treatment-refractory variants such as those with rapid-cycling. The emerging consensus is that patients on monotherapy, if followed for sufficiently long periods, will eventually require concomitant treatment to maintain a full remission. There exists a need for controlled trials that use random assignment to parallel arms including combination therapy followed by data analyses that include both relapse rate and survival techniques.

Assessing cost-effectiveness in mental health: helping policy-makers prioritize and plan health services.
We assessed, from a health sector perspective, options for change that could improve the efficiency of Australia's current mental health services by directing available resources toward 'best practice' cost-effective services. ⋯ Despite considerable methodological problems, a range of cost-effective and less cost-effective interventions for major mental disorders can be discerned. The biggest hurdle to implementation of more efficient mental health services is that this change would require reallocation of funds between interventions, between disorders and between service providers with different funding mechanisms.

Cost-effectiveness of cognitive-behavioural therapy and drug interventions for major depression.
Antidepressant drugs and cognitive-behavioural therapy (CBT) are effective treatment options for depression and are recommended by clinical practice guidelines. As part of the Assessing Cost-effectiveness -- Mental Health project we evaluate the available evidence on costs and benefits of CBT and drugs in the episodic and maintenance treatment of major depression. ⋯ A range of cost-effective interventions for episodes of major depression exists and is currently underutilized. Maintenance treatment strategies are required to significantly reduce the burden of depression, but the cost of long-term drug treatment for the large number of depressed people is high if SSRIs are the drug of choice. Key policy issues with regard to expanded provision of CBT concern the availability of suitably trained providers and the funding mechanisms for therapy in primary care.
