Improving valuation methods for the 15D instrument

This project aims at increasing the knowledge about the 15D instrument and its valuation method. We will propose solutions to identified methodological shortcomings related to 15D and aim to aid priority setting in the Norwegian healthcare sector.

About the project

Limited resources and increasing numbers of treatment options raise the need for priority setting in the health care sector. Economic evaluations are one approach to systematically quantify and compare the costs and benefits of a health intervention. In some forms of economic evaluation quality-adjusted life years (QALYs) are used to quantify the benefits of an intervention. QALYs are “life years weighted by their quality”1.  The 15D and its valuation method are used to generate value sets that are needed to calculate QALYs.

As the use of economic evaluation and the QALY in healthcare decision making in Norway increases, it is necessary to tackle methodological shortcomings in the descriptive systems and the valuation methods of HRQoL instruments like the 15D.

Objectives

  1. Elaborate the knowledge about the 15D descriptive system and its valuation method.
  2. Estimate a Norwegian 15D value algorithm and compare it to other national 15D value algorithms.
  3. Identify  which difficulties respondents face when answering the 15D descriptive system.
