Background
Utility measures | Non-utility, quantitative measures | Qualitative findings | ||
---|---|---|---|---|
Direct techniques | Indirect techniques | Direct choice techniques | Interviews | Discussion groups |
Standard gamble, time trade off, or visual analogue scales. | Pre-scored multi-attribute instruments [EQ-5D (euroQoL), the SF-6 health survey, or the health utility index (HUI-2 and HUI-3)] | Decision aids and direct choice studies. Surveys or questionnaires. | Structured, semi-structured, unstructured, or in-depth. | Focus groups. |
Methods
Development of the initial search strategy
Testing the performance of the search strategy
Relative recall = Number studies included in the SRs retrieved by the search × 100 Number of studies included in the SRs indexed in PubMed |
Systematic reviews | Topic | Techniques for elicitation of patient views and preferences of included studies |
---|---|---|
McLean 2012 [29] | Antithrombotic therapy | Elicitation of health state utility values; Choices patients made when presented with decision aids; Interviews; Surveys. |
Peasgood 2010 [41] | Breast cancer | Elicitation of health state utility values. |
Petrillo 2011 [42] | COPD | Elicitation of health state utility values. |
Bremmer 2007 [38] | Prostate cancer | Elicitation of health state utility values. |
Brooker 2013 [39] | COPD | Choices patients made when presented with decision aids; Questionnaires, surveys; Structured and semi-structured interviews. |
Morton 2010 [40] | Chronic kidney disease | Qualitative research: focus groups, interviews |
Search strategy implementation in practice
Precision: (number of relevant studies identified/total number of references retrieved from the search) X 100 Number Needed to Read (NNR): number of references needed to screen to find one relevant study (1/precision). |
