The SENIORS trial demonstrated that nebivolol is effective in the treatment of heart failure in elderly patients (e.g. > or = 70 years). This analysis evaluates the cost effectiveness of nebivolol compared with standard treatment. ⋯ This analysis indicates that nebivolol appears to be a cost-effective treatment for elderly patients with heart failure compared with standard care.

The objective of this review was to describe the performance of health-utility measures in valuing the quality-of-life (QOL) impact of changes in osteoarthritis (OA)-related chronic pain when administered within a clinical trial setting. Because the collection of utility data within a clinical trial is not always feasible in the development of health economic models, utility data from prior non-randomised studies conducted among patients with OA were also summarized. We conducted a literature review using the MEDLINE, EMBASE and PsycINFO databases. ⋯ Finally, the body of clinical trial-based utility literature in OA was found to be relatively modest, with considerably more observational studies collecting utility data. Based on the limited number of trial-based health-utility evaluations in OA to date, there can potentially be divergent findings with respect to clinical and statistical significance of changes in utility measures and corresponding measures of health status. Analysts should carefully evaluate issues of statistical power and clinical sensitivity in utilizing these measures in clinical trials of OA interventions.

Randomized Controlled Trial Multicenter Study
Escitalopram and duloxetine in major depressive disorder: a pharmacoeconomic comparison using UK cost data.
Selective serotonin reuptake inhibitors (SSRIs) and serotonin-noradrenaline reuptake inhibitors (SNRIs) are approved for the treatment of major depressive disorder (MDD). The allosteric SSRI escitalopram has been shown to be at least as clinically effective as the SNRIs venlafaxine and duloxetine in MDD, with a better tolerability profile. In addition, escitalopram has been shown to be cost saving compared with venlafaxine. ⋯ Escitalopram was associated with significantly lower duration of sick leave and significant savings in the total cost compared with duloxetine; it dominated duloxetine when effectiveness was assessed on the SDS scale. Indirect costs due to sick leave accounted for the most substantial portion of the total cost and should, therefore, be an important consideration when pharmacoeconomic comparisons between treatments are made from the societal perspective. The link between decrease in absenteeism and early (8-week) clinical improvement suggested in the additional analyses may explain the reduced sick leave observed with escitalopram, given its superior short-term efficacy compared with duloxetine (demonstrated in the underlying clinical trial).

The US Advisory Committee on Immunization Practices has recently recommended a new vaccine against herpes zoster (shingles) for routine use in adults aged > or =60 years. However, estimates of the cost effectiveness of this vaccine vary widely, in part because of gaps in the data on the value of preventing herpes zoster. Our aims were to (i) generate comprehensive information on the value of preventing a range of outcomes of herpes zoster; (ii) compare these values among community members and patients with shingles and post-herpetic neuralgia (PHN); and (iii) identify clinical and demographic characteristics that explain the variation in these values. ⋯ We believe that this study provides the most comprehensive information to date on the value individuals place on preventing herpes zoster, and it includes the only such valuation from nationally representative community members as well as patients with herpes zoster. Community members would trade substantial amounts of time or money to avoid herpes zoster, even in the least severe scenarios. The time trade-off results in this study may differ from those in other studies because of important differences in methods of assessing health utilities. Consideration of both community and patient perspectives is crucial to help decision makers fully determine the implications of their policies now that a vaccine against herpes zoster is available.

Comparative Study
Preferences of patients with diabetes mellitus for inhaled versus injectable insulin regimens.
In clinical trials, patients have expressed greater satisfaction with inhaled human insulin (EXUBERA, Pfizer) than with injectable insulin. No studies to date have attempted to quantify the strength of preferences for these alternative routes of administration. ⋯ This study highlights the utility differences that people with diabetes perceive between the prospect of inhaled and injected routes of insulin administration, even under the assumption of no difference in efficacy. These differences are magnified when the comparison in utility scores is between the majority who prefer the inhaled route and the minority who prefer the injectable route.
