[Procurement of medical devices based on cost-effectiveness data.]

Area of Science:

• Health Economics
• Medical Device Evaluation
• Health Technology Assessment

Background:

• Limited cost-effectiveness data hinders medical device procurement decisions.
• Existing methods like ICER present non-linear relationships with device unit price.
• Need for a transparent and economically sound evaluation framework for tenders.

Purpose of the Study:

• To propose a project for calculating Net Monetary Benefit (NMB) for medical devices.
• To develop a value-based scoring system for procurement and tendering processes.
• To address the paucity of cost-effectiveness data in medical device evaluation.

Main Methods:

• Calculation of Net Monetary Benefit (NMB) per patient using willingness to pay (WTP) and Quality-Adjusted Life Years (QALYs).
• NMB per patient = (WTP threshold) x (QALYs per patient) - (treatment cost per patient).
• Conversion of NMB into a tender score on a 0-100 scale for devices within the same tender lot.

Main Results:

• The NMB method offers a linear relationship between NMB and unit price, simplifying economic analysis.
• A value-based score is derived, ranging from 0 (worst pharmacoeconomic profile) to 100 (best).
• This scoring system facilitates objective comparison and selection of medical devices in tenders.

Conclusions:

• The proposed NMB calculation and value-based scoring system enhance the cost-effectiveness evaluation of medical devices.
• This approach provides a more transparent and linear method for device procurement and tendering.
• Implementation can lead to more informed and economically sound purchasing decisions for healthcare systems.
