EQ-5D bolt-ons/dimension extensions

Bolt-ons (add-ons/dimension extensions) identify key dimensions of HRQol which may be important to patients but are not captured by the EQ-5D. Until now, they have not been part of the EQ research agenda but the EuroQol Executive Committee has approved the development of a systematic, scientifically robust approach to the development of EQ-5D bolt-on dimensions for use in different clinical areas.
