Health-related quality of life and utilities among patients with depression in the Department of Veterans Affairs

Quality of Life in Treatment-Resistant Hypertension

Treatment-resistant hypertension (TRH) is an increasingly common and clinically challenging hypertension phenotype associated with adverse impact on cardiovascular events and death. Recent evidence, although limited, suggests that TRH may also adversely affect health-related quality of life (HrQoL) and other patient-reported outcomes. However, the precise mechanisms for this link remain unknown. A number of recent studies focusing on both the general hypertensive population and those with TRH suggest that patient awareness of difficult-to-control blood pressure, chronically elevated blood pressure levels, and the use of aggressive medication regimens with attendant cumulative adverse effects may play significant roles. This review summarizes the existing literature on HrQoL in persons with TRH, highlights literature from the general hypertensive population with relevance to TRH, and discusses important remaining questions regarding HrQoL in persons with TRH.

Randomized controlled trial of a health plan-level mood disorders psychosocial intervention for solo or small practices

BACKGROUND

Mood disorders represent the most expensive mental disorders for employer-based commercial health plans. Collaborative care models are effective in treating chronic physical and mental illnesses at little to no net healthcare cost, but to date have primarily been implemented by larger healthcare organizations in facility-based models. The majority of practices providing commercially insured care are far too small to implement such models. Health plan-level collaborative care treatment can address this unmet need. The goal of this study is to implement at the national commercial health plan level a collaborative care model to improve outcomes for persons with mood disorders.

METHODS/DESIGN

A randomized controlled trial of a collaborative care model versus usual care will be conducted among beneficiaries of a large national health plan from across the country seen by primary care or behavioral health practices. At discharge 344 patients identified by health plan claims as hospitalized for unipolar depression or bipolar disorder will be randomized to receive collaborative care (patient phone-based self-management support, care management, and guideline dissemination to practices delivered by a plan-level care manager) or usual care from their provider. Primary outcomes are changes in mood symptoms and mental health-related quality of life at 12 months. Secondary outcomes include rehospitalization, receipt of guideline-concordant care, and work productivity.

DISCUSSION

This study will determine whether a collaborative care model for mood disorders delivered at the national health plan level improves outcomes compared to usual care, and will inform a business case for collaborative care models for these settings that can reach patients wherever they receive treatment.

Utility Values for Adults with Unipolar Depression: Systematic Review and Meta-Analysis

BACKGROUND

Unipolar depression is a mental illness with a substantial health-related and economic burden. Health interventions for depression predominately focus on improving sufferers' health-related quality of life (HRQoL). Utility is a measure of HRQoL that is required for use in model-based cost-utility analyses to assess the added value of health interventions. This review aimed to identify, summarize, and where feasible, synthesize published utilities for unipolar depression.

METHODS

A structured electronic search combining common terms for unipolar depression and utility was conducted in MEDLINE, EMBASE, and PsycINFO. Utility values identified were summarized, and the study designs were appraised in terms of the patient population and valuation method used to generate utilities. Random-effect meta-analyses were applied to pool mean utilities identified for 3 depressive health states (mild, moderate, and severe) elicited from direct and indirect valuation methods separately.

RESULTS

Thirty-five studies were identified that reported utilities for various levels of depression severity. The most commonly used direct valuation method for eliciting utilities was standard gamble (SG) (n = 5), and the most commonly used indirect valuation method was EQ-5D (n = 20). The pooled mean (standard deviation) utilities from studies using SG as a direct valuation method were mild = 0.69 (0.14), moderate = 0.52 (0.28), and severe = 0.27 (0.26). The pooled utilities from studies using EQ-5D as an indirect valuation method were mild = 0.56 (0.16), moderate = 0.45 (0.18), and severe = 0.25 (0.15).

CONCLUSIONS

This systematic review is a useful resource for decision analysts who need health-related utility values to populate model-based cost-utility analyses of health interventions for the management of unipolar depression. Further research is necessary to understand whether direct or indirect valuation methods are the most robust sources for utilities in depression.

Impact of panic disorder on quality of life among veterans in a primary care pilot study

Panic disorder is a debilitating and costly mental health condition which commonly presents in primary care settings; however, little is known about the impact of panic disorder on quality of life and health utility valuations among Veterans in primary care. A cross-sectional investigation of quality of life was conducted in a sample of 21 Veterans with panic disorder in a VA primary care clinic. Health utilities were determined using an algorithm based upon the Medical Outcomes Study Short-Form 36 Health Survey (SF-36). Veterans in the current sample reported significantly greater impairment on all eight of the SF-36 subscales in comparison to published norms. Veterans with panic and comorbid mood disorders reported significantly greater impairment on the Vitality, Social Functioning, and Mental Health subscales, while Veterans with panic and comorbid anxiety disorders reported significantly greater impairment on the Physical Functioning and Bodily pain subscales. Health utilities for the current sample were comparable to previous reports of Veterans with PTSD and depression, as well as health utilities of persons with chronic pulmonary disease and irritable bowel syndrome. The findings from this study highlight the devastating nature of panic disorder and reflect the need for increased attention to the identification and treatment of panic disorder in VA primary care settings.
