ABSTRACT Panic disorder is a prevalent, often disabling, disorder among primary-care patients, but there are large gaps in quality of treatment in primary care. This study describes the incremental cost-effectiveness of a combined cognitive behavioral therapy (CBT) and pharmacotherapy intervention for patients with panic disorder versus usual primary-care treatment.
This randomized control trial recruited 232 primary-care patients meeting DSM-IV criteria for panic disorder from March 2000 to March 2002 from six primary-care clinics from university-affiliated clinics at the University of Washington (Seattle) and University of California (Los Angeles and San Diego). Patients were randomly assigned to receive either treatment as usual or a combined CBT and pharmacotherapy intervention for panic disorder delivered in primary care by a mental health therapist. Intervention patients had up to six sessions of CBT modified for the primary-care setting in the first 12 weeks, and up to six telephone follow-ups over the next 9 months. The primary outcome variables were total out-patient costs, anxiety-free days (AFDs) and quality adjusted life-years (QALYs).
Relative to usual care, intervention patients experienced 60.4 [95% confidence interval (CI) 42.9-77.9] more AFDs over a 12-month period. Total incremental out-patient costs were 492 US dollars higher (95% CI 236-747 US dollars ) in intervention versus usual care patients with a cost per additional AFD of 8.40 US dollars (95% CI 2.80-14.0 US dollars ) and a cost per QALY ranging from 14,158 US dollars (95% CI 6,791-21,496 US dollars ) to 24,776 US dollars (95% CI 11,885-37,618 US dollars ). The cost per QALY estimate is well within the range of other commonly accepted medical interventions such as statin use and treatment of hypertension.
The combined CBT and pharmacotherapy intervention was associated with a robust clinical improvement compared to usual care with a moderate increase in ambulatory costs.

    ABSTRACT: Objective : Generalized anxiety and panic disorder are a burden on society because they are costly and have a significant adverse effect on quality of life. The aim of this study was to evaluate the cost-utility of a collaborative stepped care intervention for panic disorder and generalized anxiety disorder in primary care compared to care as usual from a societal perspective. Methods : The design of the study was a two armed cluster randomized controlled trial. In total 43 primary care practices in the Netherlands participated in the study. Eventually, 180 patients were included (114 collaborative stepped care, 66 care as usual). Baseline measures and follow up measures (3, 6, 9 and 12 months) were assessed using questionnaires. We applied the TiC-P, the SF-HQL and the EQ-5D respectively measuring health care utilization, production losses and health related quality of life. Results : The average annual direct medical costs in the collaborative stepped care group were 1,854 Euro (95% CI, 1,726 to 1,986) compared to € 1,503 (95% CI, 1,374 to 1,664) in the care as usual group. The average quality of life years (QALY's) gained was 0.05 higher in the collaborative stepped care group, leading to an incremental cost effectiveness ratio (ICER) of 6,965 Euro per QALY. Inclusion of the productivity costs, consequently reflecting the full societal costs, decreased the ratio even more. Conclusion : The study showed that collaborative stepped care was a cost effective intervention for panic disorder and generalized anxiety disorder and was even dominant when a societal perspective was taken.

    ABSTRACT: Rising mental health costs have brought with them the pressing need to identify cost-effective treatments. Identifying cost-effective treatments for depression among Latinos is particularly relevant given substantial disparities in access to depression treatment for Latinos compared to non-Latino whites.

    ABSTRACT: International studies suggest that cognitive-behavioural therapy (CBT) for the treatment of mental disorders results in improved clinical and economic outcomes. In Canada, however, publicly funded CBT is scarce, representing an inequity in service delivery. A research framework to evaluate the Canadian health economic impact of increasing access to CBT is proposed. Canadian data related to the epidemiology of mental disorders, patterns of usual care, CBT effectiveness, resource allocation and costs of care will be required and methodologies should be transparent and outcomes meaningful to Canadian decision-makers. Findings should be delivered by multidisciplinary teams of researchers and health professionals. Barriers to funding reform must be identified and knowledge translation strategies delineated and implemented. Canadian clinical and economic outcomes data are essential for those seeking to provide decision-makers with the evidence they need to evaluate whether CBT represents value for mental health dollars spent.
