This chapter presents how Germany supports patient involvement in health technology assessment (HTA) and decision-making processes in the Federal Joint Committee (Gemeinsamer Bundesausschuss, G-BA) and the Institute for Quality and Efficiency in Healthcare (Institut für Qualität und Wirtschaftlichkeit im Gesundheitswesen, IQWiG), which drafts HTA reports commissioned by the G-BA. It outlines processes for incorporating individual and collective patient experiences through participation processes and research at the Innovation Fund, and it shows how Germany has set a legal framework for patient participation. In particular, it illustrates how patient organisations use their rights by filing requests for HTAs and decision-making regarding benefit coverage and by identifying patient representatives with different perspectives to take part in assessment and appraisal processes. In conclusion, the chapter reflects on issues of evaluation and future challenges.
