Development of internet-capable utility elicitation instruments Download PDF EPUB FB2
This book is about elicitation: the facilitation of the quantitative expression of subjective judgement about matters of fact, interacting with subject experts, or about matters of value, interacting with decision makers or stakeholders. It offers an integrated presentation of procedures and processes that allow analysts and experts to think clearly about numbers, particularly the inputs for Format: Hardcover.
Utility Elicitation Using Single-Item Questions Compared with a Computerized Interview Article (PDF Available) in Medical Decision Making 21(2) April with 17 Reads How we measure. The development of the Internet demonstrates that federal support for research, applied at the right place and right time, can be extremely effective.
DARPA's support gave visibility to the work of individual researchers on packet switching and resulted in the development. This Development of internet-capable utility elicitation instruments book is used in an experimental study to elicit individual utility and probability weighting functions for monetary outcomes in the gain and loss domains.
Concave utility functions are obtained for gains and convex utility functions for by: Whether such instruments increase the reliability and validity of utility assessment relative to standard utility elicitation or utilities derived from generic health indexes is uncertain.
Our careful systematic approach is designed to improve the reliability and validity of utility by: This paper presents the requirement elicitation process and techniques used in the development process of an open collaboration and innovation platform – [email protected] which is an experimental.

Pictures were processed using Photoshop (Adobe, Mountain View, CA) for Macintosh computers (Apple Computer, Cupertino, CA) coupled with the text descriptions of each health state.
13, 16 The program was developed using IMPACT, an authoring system designed to allow health professionals to construct multimedia utility survey instruments. 17 All instructions were displayed on the screen.
Before the actual utility elicitation, the subjects underwent an example evaluating the health state of paralysis to become familiar with the prop and the technique.

A large majority of the submissions (84%) used a choice-based elicitation method to generate utility values, in line with the NICE Methods Guide requirements.
The most common method was the time trade-off, which was used in 54% of by: We describe further development of a multimedia utility elicitation instrument that is highly portable and easily accessible. An earlier version, FLAIR1, introduced features designed for older. Based on a critical review of published cost-utility studies in child health, among the approaches cited for implementing cost-utility analysis in pediatric populations include the explicit development of a generic instrument designed to be applicable across child and adult populations.

Surprisingly, their finding showed that while Google is superior for coverage and accessibility, library systems are superior for quality of.
Abstract. Objective: The purpose of this study was to assess the reliability and internal consistency of measurements of utilities performed with a computer program (iMPACT2) designed for Internet surveys and Internet patient decision-support s: We implemented the Internet Multimedia Preference Assessor Construction Tool, version 2 (iMPACT2) program using the combination of a web Cited by: Using good design and appropriate analysis should allow researchers to account for many of the issues raised above in Recommendations for the design of health-utility data collection during the protocol development for a planned clinical trial.

The Health Utilities Index Mark 3 (HUI3) is a generic multi-attribute, preference-based system for assessing health-related quality of life.
It is widely used overseas as an outcome measure and for estimating quality-adjusted life years. We aimed to estimate a multi-attribute and eight single-attribute utility functions for the HUI3 system based on community preferences in Japan. The utility theory provides multiple elicitation methods.
Two well-known methods are the time trade-off (TTO) and standard gamble (SG),[ 2 ] which work with hypothetical scenarios. To value a suboptimal health state S, in TTO, the interviewee must choose between living his expected lifetime (T1) in the S state or to live shorter (T2 Author: Elisa Salvi, Enea Parimbelli, Silvana Quaglini, Lucia Sacchi.
s, with the desktop computer, and the development of the Internet and digital photography, autophotography has become more popular as a visual methodology in qualitative research (Thomas, ).
Collier and Collier () were pioneers in photographic methods and have written much about this research method. Their widely used book: Visual. most instruments performing utility elicitation in several potentially important ways: (1) the response is measured as the answer to an single-item, open-ended question rather than the result of a “forced choice” or matching task; (2) there is no graphic or verbal feedback on trade-offs; and (3) there is no training of subjects in utility.

The first category included studies (n=11) that use HRQOL measures, both generic (eg, EQ-5D) and disease specific, to describe patient health status/QOL and elicit health utilities with the potential use of these utilities in future economic evaluations.9,14–23 The second group comprised studies (n=3) that described the development and/or validation of mapping algorithms between disease-specific Cited by: 8.
This paper reports the results of an experimental parameter-free elicitation and decomposition of decision weights under uncertainty. Assuming cumulative prospect theory, utility functions were elicited for gains and losses at an individual level using the tradeoff by: Voluntary environmental programs (VEPs) have become increasingly popular around the world to address energy efficiency issues that mandatory building codes have not been able to tackle.
Even though the utility of voluntary schemes is widely debated, they have become a de facto reality for many professionals in the building and construction sector.

However, its potential utility and the fact that it is widely advocated in cost risk analysis require that we understand how to do it. Introduction Generic instruments for assessing health-related quality of life may lack the sensitivity to detect changes in health specific to certain conditions, such as dementia.

Key stakeholders regard generic utility instruments as suitable tools to inform health technology assessment decision-making regarding allocation of resources across competing interventions.
These instruments require a 'descriptor', a 'valuation' and a 'perspective' of the economic by:. Computer-based utility elicitation procedures to administer the TTO have been developed, for example iMPACT3 and U-Titer.
