BACKGROUND This study compares differences in quality-adjusted life expectancy across the eight original National Occupational Research Agenda (NORA) industry sectors. METHODS Data from the 1997 to 2012 National Health Interview Survey (NHIS) were used to estimate quality-adjusted life years (QALYs) for all workers and by NORA sector. Differences in QALYs were calculated and translated into e...
We used data from a 4-year prospective study of 2,558 primary care patients age 65 and older in a large staff model health maintenance organization to examine the association of clinically significant depressive symptoms and eight other chronic medical conditions with quality adjusted life years (QALYs). We developed linear regression models to examine the association of clinically significant ...
Quality-adjusted life years (QALY) utility models are multiattribute utility models of survival duration and health quality. This paper formulates six classes of QALY utility models and axiomatizes these models under expected utility (EU) and rank-dependent utility (RDU) assumptions. The QALY models investigated in this paper include the standard linear QALY model, the power and exponential mul...
Scaling instruments for the measurement of quality-adjusted life years (QALYs) incorporate either a personal or an impersonal perspective on the benefits of a health intervention and either do or do not incorporate considerations of equity. This paper sets out three hypotheses concerning perspective and equity: 1) that more equally distributed benefits will be preferred to less equally distribu...
BACKGROUND falls-related self-efficacy is associated with falls, falls-related injury and subsequent functional decline which may lead to poor health-related quality-of-life (HRQL). To our knowledge, no previous studies have examined the independent contribution of falls-related self-efficacy to HRQL. Our primary objective was to determine whether falls-related self-efficacy is independently as...
OBJECTIVE Compare differences in health-related quality of life among blacks and whites to examine if race, diabetes, and visual impairment (VI) present a triple disadvantage in terms of quality-adjusted life expectancy. RESEARCH DESIGN AND METHODS Data were analyzed from the 2000-2003 Medical Expenditure Panel Survey, a nationally representative survey that contains the EuroQol 5D (EQ-5D). T...
BACKGROUND There is a debate in the health economics literature concerning the most appropriate way of applying Amartya Sen's capability approach in economic evaluation studies. Some suggest that quality-adjusted life years (QALYs) alone are adequate while others argue that this approach is too narrow and that direct measures of capability wellbeing provide a more extensive application of Sen's...
BACKGROUND Guidelines for anticoagulant therapy in patients with atrial fibrillation are based on stroke risk as calculated by either the CHADS2 or the CHA2DS2VASc scores and do not integrate bleeding risk in an explicit, quantitative manner. Our objective was to quantify the net clinical benefit resulting from improved decision making about antithrombotic therapy. METHODS AND RESULTS This st...
Five percent of all pregnant women and 25% of pregnant women with insulin-dependent diabetes mellitus (IDDM) develop postpartum thyroiditis (PPT) during the first year after delivery. PPT has significant morbidity and can be predicted prenatally by the presence of thyroid peroxidase (TPO) antibody. Our objective was to estimate the cost-effectiveness of screening pregnant women for the TPO anti...
