BackgroundAccording to German law, health-related quality of life is a relevant criterion in the early assessment of the benefits of drug treatment. In spite of its regulatory importance, the role of quality of life assessment in quantifying the additional benefits of novel vs standard treatments is not yet clear.ObjectivesThe paper is aimed at analyzing the theoretical foundation, the methodological foundation, and the empirical evaluation of the criterion "quality of life" in recent benefit dossiers, as published by the Federal Joint Committee (G-BA) and the German Institute for Quality and Efficiency in Health Care (IQWiG).Materials And MethodsBenefit dossiers assessed by the end of 2013 were quantitatively analyzed regarding the choice, frequency of use, and consequences of quality of life assessment.ResultsIn 59 of the 66 dossiers quality of life assessment was performed, frequently using the EQ-5D (n = 16 procedures) and the SF-36 (n = 8 procedures). Of the 107 evaluations of the subpopulation within these 59 dossiers, in only 2 cases was an additional benefit due to the quality of life declared by the IQWiG and G-BA.ConclusionsIn spite of the acceptance of quality of life measures and their inclusion in the dossiers, they have rarely been the basis for the declaration of additional benefits. This reluctance does not stem from the availability of instruments, but results from problems in their selection, the design and conduct of the study, data interpretation, together with shortcomings regarding the statistical and clinical significance of quality of life data.
