Abstract:Relative to their current health, RA patients assigned low preference values to many glucocorticoid adverse events, particularly those associated with chronic fracture outcomes. Results varied with the preference measure used, indicating that methodological attributes of preference determinations must be considered in clinical decision making.

“…This process left 94 articles eligible for data entry. Thirty-one articles were excluded because they reported only patient preferences (n 5 14) [22][23][24][25][26][27][28][29][30][31][32][33][34][35], population preferences (n 5 14) [36][37][38][39][40][41][42][43][44][45][46][47][48][49], or proxy preferences (n 5 3) [50][51][52]. Two articles reported mixed patient and proxy preferences and compared these with population preferences [53,54].…”

“…In this approach, the respondent is asked for the amount of time he or she is willing to spend sleeping in a non-restful state compared with time spent in a temporary health state. [36,37] This approach avoids the need for discounting. As with all variations of the TTO, it allows for investigator discretion in the description of the health states, and thus domains can be customized for temporary health states.…”
A variety of methods are available to measure preferences for temporary health states for cost-utility analyses. The objectives of this review were to summarize the available temporary health-state valuation methods, identify advantages and disadvantages of each, and identify areas for future research. We describe the key aspects of each method and summarize advantages and disadvantages of each method in terms of consistency with QALY theory, relevance to temporary health-state-specific domains, ease of use, time preference, and performance in validation studies. Two broad categories of methods were identified: traditional and adapted. Traditional methods were health status instruments, time trade-off (TTO), and the standard gamble (SG). Methods adapted specifically for temporary health-state valuation were TTO with specified duration of the health state, TTO with a lifespan modification, waiting trade-off, chained approaches for TTO and SG, and sleep trade-off. Advantages and disadvantages vary by method and no 'gold standard' method emerged. Selection of a method to value temporary health states will depend on the relative importance of the following considerations: ability to accurately capture the unique characteristics of the temporary health state, level of respondent burden and cognition, theoretical consistency of elicited preference values with the overall purpose of the study, and resources available for study development and data collection. Further research should focus on evaluating validity, reliability and feasibility of temporary health-state valuation methods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
