Objectives: The HTA Core Model is a framework for producing health technology assessments (HTAs) in a structured format. The Model splits the content of a HTA into assessment elements. The objective is to explore the adaptability of these assessment elements in national report production in a pilot case study comparing a national HTA report and the HTA Core Model.

Methods: An on-going Dutch HTA report on endovascular repair of abdominal aortic aneurysm (EVAR) was chosen as a typical representative of a national report on medical interventions. The author of the EVAR report assessed the relevance and comprehensiveness of the assessment elements of the HTA Core Model for her work. Another researcher annotated the Core Model specific content in the EVAR report. Matching and missing content, as well as the distribution of information in the EVAR report were tabulated and analysed in joint deliberations.

Results: Forty percent of the assessment elements of the Core Model were considered relevant for the EVAR report. Some issues relevant for EVAR but missing from the Core Model were identified: they were about re-interventions, secondary prevention, subpopulations that benefit most, and the length of the hospital stay. The distribution of information differed substantially between the Code Model and the national report.

Conclusions: The assessment elements of the HTA Core Model covered most relevant questions of the national report. In order to facilitate easy adaptation of information, the distribution of information should be more consistent in the national report and the Core model.
