Abstract
PURPOSE To investigate time trade-off (TTO) utility values in patients with noninfectious uveitis and determine whether patient demographics and clinical characteristics are associated with utility scores. DESIGN Time trade-off utility analysis. METHODS Setting: A tertiary care uveitis center in San Francisco, California, USA. PATIENT POPULATION One hundred and four consecutive adults with noninfectious uveitis, enrolled between November 2016 and February 2017. MAIN OUTCOME MEASURES TTO utility values, as collected by an interviewer-guided survey. Information regarding general health, ocular symptoms, and religion was also collected and medical record review was conducted to record anatomic location of uveitis, disease activity, visual acuity, and treatments. Multivariable regression analysis with backward selection was used to identify variables associated with TTO values. RESULTS Median TTO score was 0.975 (interquartile range [IQR]: 0.8-1.0), corresponding to trading a median 1.28 years of remaining life for healthy eyes (IQR: 0-6.29). Regression analysis revealed that worse eye visual acuity, >6 months of oral corticosteroid use, and current antidepressant use were associated with lower TTO scores (P = .008, P = .006, P = .008, respectively), controlling for age and sex. In particular, patients who had been taking oral corticosteroids for more than 6 months, regardless of dose, were 10.5 times more likely to trade 20% or more years of remaining life (TTO ≤0.8) than patients not taking oral corticosteroids (95% confidence interval: 2.3, 48.1; P = .002). CONCLUSIONS Patients with noninfectious uveitis had measurable, though modest, reductions in quality of life, as assessed by TTO, and these decreases were significantly associated with visual acuity in the worse eye and long-term oral corticosteroid use.

The Role of Patients' Age on Their Preferences for Choosing Additional Blood Pressure-Lowering Drugs: A Discrete Choice Experiment in Patients with Diabetes. PLoS One 2015; 10:e0139755.

Abstract
Objectives To assess whether patients’ willingness to add a blood pressure-lowering drug and the importance they attach to specific treatment characteristics differ among age groups in patients with type 2 diabetes. Materials and Methods Patients being prescribed at least an oral glucose-lowering and a blood pressure-lowering drug completed a questionnaire including a discrete choice experiment. This experiment contained choice sets with hypothetical blood pressure-lowering drugs and a no additional drug alternative, which differed in their characteristics (i.e. effects and intake moments). Differences in willingness to add a drug were compared between patients <75 years (non-aged) and ≥75 years (aged) using Pearson χ2-tests. Multinomial logit models were used to assess and compare the importance attached to the characteristics. Results Of the 161 patients who completed the questionnaire, 151 (72%) could be included in the analyses (mean age 68 years; 42% female). Aged patients were less willing to add a drug than non-aged patients (67% versus 84% respectively; P = 0.017). In both age groups, the effect on blood pressure was most important for choosing a drug, followed by the risk of adverse drug events and the risk of death. The effect on limitations due to stroke was only significant in the non-aged group. The effect on blood pressure was slightly more important in the non-aged than the aged group (P = 0.043). Conclusions Aged patients appear less willing to add a preventive drug than non-aged patients. The importance attached to various treatment characteristics does not seem to differ much among age groups.

Abstract
The metric of disability-adjusted life years (DALYs) has become the global standard of measuring burden of disease. DALYs are comprised of years of life lost due to premature mortality and years of healthy life lost due to living with disability. In order to calculate the second part of the DALY equation, disease specific disability weights have to be established, i.e. measures for the decline of health associated with these disease states, which vary between zero for perfect health and one for death. Although these disability weights are key for estimating DALYs, there have not been many comprehensive studies with empirical determinations of them. This article describes a systematic review on the state of the art with respect to empirically determining disability weights. Based on this review, a multi-method approach is outlined, which has also been implemented in a US study to measure burden of disease. This approach involves the use of psychometric methodology as well as economic trade-off methods for determining the value of health states. It is conceptualized as a disaggregated approach, where the disability weight of any health state can be calculated if the attributes of this health state are known. The US study received the collaboration of experts from more than 20 institutes of the National Institutes of Health and of the Centers for Disease Control and Prevention. First results will be available by the end of this year.

Abstract
OBJECTIVES Chronic hepatitis B (CHB) is a condition that results in substantial morbidity and mortality worldwide because of progressive liver damage. Investigators undertaking economic evaluations of new therapeutic agents require estimates of health-related quality of life (HRQOL). Recently, evidence has begun to accumulate that differences in cultural backgrounds have a quantifiable impact on perceptions of health. The objective was to elicit utilities for six health states that occur after infection with the hepatitis B virus from infected and uninfected respondents living in jurisdictions with low and with high CHB endemicity. METHODS Standard gamble utilities were elicited from hepatitis patients and uninfected respondents using an interviewer-administered survey in the United States, Canada, United Kingdom, Spain, Hong Kong, and mainland China. Generalized linear models were used to the effect on utilities of current health, age and sex, jurisdiction and, for infected respondents, current disease state. RESULTS The sample included 534 CHB-infected patients and 600 uninfected respondents. CHB and compensated cirrhosis had a moderate impact on HRQOL with utilities ranging from 0.68 to 0.80. Decompensated cirrhosis and hepatocellular carcinoma had a stronger impact with utilities ranging from 0.35 to 0.41. Significant variation was observed between countries, with both types of respondents in mainland China and Hong Kong reporting systematically lower utilities. CONCLUSIONS Health states related to CHB infection have substantial reductions in HRQOL and the utilities reported in this study provide valuable information for comparing new treatment options. The observed intercountry differences suggest that economic evaluations may benefit from country-specific utility estimates. The extent that systematic intercountry differences in utilities hold true for other infectious and chronic diseases remains an open question and has considerable implications for the proper conduct and interpretation of economic evaluations.

Abstract
The purpose of this report was to perform a systematic review and meta-analysis of the studies examining the impact of an elevated body mass index (BMI) on mortality risk in elderly (> or =65 years) men and women. A variance-based method of meta-analysis was used to summarize the relationships from available studies. The summary relative risk of all-cause mortality from the 26 analyses that included a risk estimate for a BMI within the overweight range was 1.00 (95% confidence intervals, 0.97-1.03). The summary relative risk of all-cause mortality for the 28 analyses that included a risk estimate for a BMI within the obese range was 1.10 (1.06-1.13). These calculations indicate that a BMI in the overweight range is not associated with a significantly increased risk of mortality in the elderly, while a BMI in the moderately obese range is only associated with a modest increase in mortality risk.

Abstract
Generic and disease-specific instruments have been used to assess health-related quality of life (HRQoL) in hemophilia. However, HRQoL measures also need to reflect patient preferences for various hemophilia health states. The goal of this project was to develop a disease-specific utility instrument that measures patient preferences for various health states unique to hemophilia. The visual analog scale (VAS) and the standard gamble (SG) methods were used. Study participants (n = 128) were tested and stratified into paediatric and adult groups. Test-retest reliability was demonstrated for both instruments, with r = 0.91 for the VAS and r = 0.79 for the SG. When comparing results by age group, statistically significant differences were observed between paediatric and adult participants with the SG instrument (P = 0.045), with older participants taking more risk overall. However, no significant differences based on age were seen when using the VAS (P = 0.636). Statistically significant differences were observed between the VAS and SG instruments within both the paediatric and adult groups (P < 0.0001). In general, the SG yielded higher preference scores than the VAS for the majority of health states. Results derived from the SG instrument indicate that age can influence patients' preferences regarding their state of health. This can have implications for considering treatment options based on the mean age of the population under consideration. Both instruments demonstrated reliability and validity indicating that they could be used to assess patient preferences in hemophilia. However, preference score differences indicate that the two measures may not be interchangeable.

Abstract
We investigated the correlation between descriptive and valuational measures of health-related quality of life (HRQL) and assessed determinants affecting these measures. Our suspicion was that there is little similarity in the content of descriptive and valuational measures of HRQL. We thus conducted a cross-sectional observational study of 56 hemodialysis patients. All underwent structured interviews. Dependent variables were patients utilities [time trade-off (TTO)], global rating of HRQL and generic HRQL (SF-36). Independent variables were socioeconomic details, disease severity, comorbidity, symptoms, depression, social support, and laboratory data. The correlation between TTO and global HRQL was -0.33 (P = .0178) and between TTO and the SF-36 physical and mental summary scores -0.16 (P = .2383) and -0.20 (P = .1443), respectively. The regression models for the SF-36 physical and mental summary scores explained 75% and 64% of the variance, and for global HRQL 29% of the variance. The independent variables had no effect on the TTO. This confirmed our suspicion that a qualitative difference exists between TTO and descriptive quality of life tools. The TTO content could not be explained by the variables that entail the content of HRQL instruments.

Abstract
BACKGROUND Comprehensive geriatric assessment (CGA) can be effective in inpatient units, but such inpatient settings are prohibitively expensive. If similar benefits could be obtained in outpatient settings, CGA might be a more attractive option. OBJECTIVES To assess the cost-effectiveness (CE) of an outpatient geriatric assessment with an intervention to increase adherence. SUBJECTS Three hundred fifty-one community-dwelling, elderly subjects with at least one of four geriatric conditions. MEASURES In addition to the measures of functioning, we collected data on the costs of the intervention itself and on the use of medical services in the 64 weeks after the intervention. RESULTS The intervention, which prevented functional decline, cost $273 per participant. The intervention group averaged three more visits than the control group in the first 32 weeks after the intervention, but only 1.2 extra visits in the next 32 weeks. We estimate that the costs of these additional medical services would be $473 for the 5 years after the intervention, leading to a total cost per Quality Adjusted Life Year (QALY) of $10,600. CONCLUSIONS The CE of this program compares favorably with many common medical interventions. Whether investments should be made in health care resources on treatments that lead to modest improvements in the functioning of community-dwelling elderly people remains a societal decision.
