Performance of Search Filters to Identify Health State Utility Studies
The study was conducted in 3 phases. In each phase, filter performance was assessed by measuring relative recall (RR) of a QGS set of relevant studies, calculating sensitivity, precision and NNR. 3 QGS sets (QGS1, QGS2, QGS3) of relevant studies were harvested from systematic reviews of studies reporting HSUVs, and from 10 manufacturers' submissions for NICE Single Technology Assessments which had conducted reviews of studies reporting HSUVs.
