Cost-effectiveness of specialized treatment based on cognitive behavioral therapy versus usual care for tinnitus.

OBJECTIVE: To evaluate the cost-effectiveness of specialized multidisciplinary tinnitus treatment based on cognitive behavioral therapy, compared with care as usual. DESIGN: Randomized controlled trial including an economic evaluation from a health-care and societal perspective, using a one-year time horizon. SETTING: Audiologic center. PATIENTS: A referred sample of 626 patients with tinnitus were eligible for participation. Approximately 492 patients were included in the study. Eighty-six (35%) of 247 patients in the usual care group, and 74 (30%) of 245 patients in the specialized care group were lost to follow-up by month 12. MAIN OUTCOME MEASURES: Quality adjusted life years (QALYs) as measured with the Health Utilities Index Mark III and cost in US dollars. RESULTS: Compared with patients receiving usual care, patients who received specialized care gained on average 0.015 QALYs (95% bootstrapped confidence interval [BCI], -0.03 to 0.06). The incremental costs from a societal perspective are $357 (95% BCI,-$1,034 to $1,785). The incremental cost per QALY from a societal perspective amounted to $24,580. The probability that SC is cost-effective from a societal perspective is 58% for a willingness to pay for a QALY of $45,000. CONCLUSION: Specialized multidisciplinary tinnitus treatment based on cognitive behavioral therapy is cost-effective as compared with usual care. Although uncertainty surrounding the incremental costs and effects is considerable, sensitivity analysis indicated that cost-effectiveness results were robust.

Tinnitus: a cost study.

OBJECTIVES: The aim of this study was to examine the costs of tinnitus in The Netherlands from a health care and a societal perspective. Furthermore, the impact of disease characteristics and demographic characteristics on these costs were examined. METHODS: A bottom-up cost of illness study was performed, using the baseline data on a cost questionnaire of a randomized controlled trial investigating the (cost) effectiveness of an integral multidisciplinary treatment for tinnitus versus care as usual. Mean yearly costs were multiplied by the prevalence figure of tinnitus for the adult general population to estimate the total cost of illness of tinnitus to society. Because cost data usually are not normally distributed, a nonparametric bootstrap resampling procedure with 1000 simulations was performed to determine statistical uncertainty of the cost estimates per category. Several questionnaires measuring disease and demographic characteristics were administered. The impact of disease characteristics and demographics on costs was investigated using a multivariate regression analysis. RESULTS: Total mean societal cost of illness was €6.8 billion (95% confidence interval: €3.9 billion-€10.8 billion). The larger part of total cost of illness was not related to health care. Total mean health care costs were €1.9 billion (95% confidence interval: €1.4 billion-€2.5 billion). Significant predictors of both health care costs and societal costs were tinnitus severity, age, shorter duration of tinnitus, and more severe depression. CONCLUSION: The economical burden of tinnitus to society is substantial, and severity of tinnitus is an important predictor of the costs made by patients.

Activity pacing in chronic pain: concepts, evidence, and future directions.

BACKGROUND: Activity pacing (AP) is a concept that is central to many chronic pain theories and treatments, yet there remains confusion regarding its definition and effects. OBJECTIVE: To review the current knowledge concerning AP and integrate this knowledge in a manner that allows for a clear definition and useful directions for future research. METHODS: A narrative review of the major theoretical approaches to AP and of the empirical evidence regarding the effects of AP interventions, followed by an integrative discussion. RESULTS: The concept of AP is derived from 2 main traditions: operant and energy conservation. Although there are common elements across these traditions, significant conceptual and practical differences exist, which has led to confusion. Little empirical evidence exists concerning the efficacy of AP as a treatment for chronic pain. DISCUSSION: Future research on AP should be based on a clear theoretical foundation, consider the context in which the AP behavior occurs and the type of pacing problem ("underactivity" vs. "overactivity"), and should examine the impact of AP treatment on multiple clinical outcomes. We provide a provisional definition of AP and specific recommendations that we believe will move the field forward.

Older people's preferences regarding programme formats for managing concerns about falls.

OBJECTIVE: to explore the preferences of community-dwelling older persons regarding different programme formats for managing concerns about falls. SUBJECTS AND DESIGN: cross-sectional study of 5,755 community-dwelling people aged ≥ 70 years in the Netherlands. METHODS: a questionnaire assessed people's willingness to participate per programme format (n=6), i.e. a programme at home, via telephone, via home visits and telephone consultations, via television or via Internet. RESULTS: of the 2,498 responders, 62.7% indicated no interest in any of the formats. The willingness to participate per programme format varied between 21.5 (at home) and 9.4% (via Internet). Among people interested in at least one of the formats (n=931), higher levels of fall-related concerns were associated with increased preference for a programme with home visits. Poor perceived health and age ≥ 80 years were associated with less preference for a group programme. Higher educated people were more in favour of a programme via Internet compared with their lower educated counterparts. CONCLUSION: the majority of community-dwelling older people are not likely to participate in any of the six proposed programme formats for managing concerns about falls. However, when diverse formats of effective programmes will be made available, uptake and adherence may be increased since programme preferences are associated to specific population characteristics.

Assessment of health state in patients with tinnitus: a comparison of the EQ-5D and HUI mark III.

OBJECTIVES: Expressing the outcomes of treatment in quality-adjusted life years is increasingly important as a tool to aid decision makers concerning the allocation of scarce resources within the health care sector. A quality-adjusted life year is a measure of life expectancy that is weighted by health-related quality of life. These weights are referred to as utility scores and are usually measured by multiattribute utility measures. Several studies found that different utility measures provide different estimates of the same person's level of utility. The aim of this study was to investigate which of two widely used utility measures, the EQ-5D and the HUI mark III, is preferred in a tinnitus population. METHODS: Baseline and follow-up data on EQ-5D and HUI mark III of 429 patients of a randomized controlled clinical trial, investigating cost-effectiveness of usual care versus specialized care of tinnitus, were included. Agreement, discriminative power, and responsiveness of the health state description and the utility scores were examined. RESULTS: Corresponding dimensions of the EQ-5D and HUI mark III showed large correlations; although ceiling effects were more frequently observed in the EQ-5D. Mean utility scores for EQ-5D (0.77; SD 0.22) and HUI mark III (0.64; SD 0.28) were significantly different (Wilcoxon signed ranks test, p < 0.001), and agreement was low to moderate (intraclass correlation coefficient = 0.53). Both health state description and utility scores of both measures discriminated between different severity groups. These groups were based on baseline scores of the Tinnitus Questionnaire. The HUI mark III had a higher ability than the EQ-5D to detect improved patients from randomly selected pairs of improved and unimproved patients. CONCLUSION: This study shows that different utility measures lead to different health state descriptions and utility scores among tinnitus patients. However, both measures are capable of discriminating between clinically different groups. The HUI mark III is more responsive than the EQ-5D, and therefore preferred in a tinnitus population.
