PP72 Using INTEGRATE-HTA On The Example Of Rasterstereography For Scoliosis

Introduction Full health technology assessment (HTA) reports discuss not only the safety and efficacy of a technology, but also the economic, ethical, legal, socio-cultural, and organizational aspects. INTEGRATE-HTA is a completed European Union project that developed concepts and methods for a patient-centered, integrated assessment of complex technologies. Technologies can be considered complex if they are characterized by a large number of interacting components, a wide variability of outcomes, or a high degree of flexibility. In contrast to the usual linear approach of addressing individual HTA domains separately, the INTEGRATE-HTA methodology is based on the assumption that different aspects of the domains interact. From the very beginning, these interactions are captured systematically using various tools. Continuous reflection and compaction of these relations can lead to an extended perspective on a technology. As a result, complexity and mechanisms of action open up, helping to channel public discussion and implementation. We investigated whether using the INTEGRATE-HTA methodology improves the understanding of individual domains and their interactions. Methods According to the methodology, an initial logic model for rasterstereography in patients with scoliosis was developed and successively expanded. A synoptic table, showing multiple maps of individual aspects to domains, and a complexity checklist were used. In addition, harvest plots were created and the socio-cultural impact of the disease was highlighted as a semantic complex. A final logic model and an interaction figure were established to initiate discussion. Results Having been classified as slightly complex in the beginning, rasterstereography turned out to be highly complex after using a variety of tools and a final graphical representation; the multiple mapping of individual aspects to domains resulted in a high density of interactions. Conclusions The INTEGRATE-HTA methodology helped to identify interactions between domains and significantly expanded the perspective on a technology. It improved patient-centered understanding and facilitated the discussion of single aspects.
