There is a number of the formulas for calculation of the cost-effectiveness of the projects, novel treatment modalities, surgery, drugs etc.
But how to calculate the cost-effectiveness of the diagnostic questionnaire?
How to retrieve the cost of analyses from the countries with the system of Health insurance? Should I take into account interests of the insurance companies?
Thank you all in advance for your answers.
That is not a simple question! Did you have a look at recommendations/guidelines for cost-effectiveness evaluation? E.g.:
https://www.researchgate.net/publication/308092668_Recommendations_for_Conduct_Methodological_Practices_and_Reporting_of_Cost-effectiveness_Analyses_Second_Panel_on_Cost-Effectiveness_in_Health_and_Medicine
and the book from the same panel:

ISPOR does not focus on diagnostics but has some very useful things on their web site:

NICE has some guidance for what they want to see:

Diagnostic tools present a complex challenge in cost-effectiveness analyses. In general, before you can start, you need to understand the value of the information provided by the new diagnostic tool, in terms of how it changes treatment decisions and outcomes. Specifically:
- What is the current process of care?
- At what point in the process is the new diagnostic information utilized?
- For how many -- and which -- patients is the tool expected to yield information that differs from the previous information or assumption?
- Among those patients, what proportion will have a change in care as a result of the new information?
- How exactly will treatment change?
- How does the effectiveness of the new treatment (including major or costly side effects) differ from the effectiveness of the treatment the patient would otherwise have received (including major or costly side effects)?
Once you have modeled how your diagnostic tool changes treatment paths and outcomes -- and for whom -- you can apply costs/utilities in accordance with your analytical objectives. It's a challenge, but if you walk though the logic you will see quickly that the value of a diagnostic tool is often governed by the effectiveness of the treatments that might be applied as a result of the new information.
My dear colleagues, Dr. Funk, Dr.Brenna and Dr. Boer!
Thank you for your priceless and detailed clarifications. You have provided me with a lot of useful information.
