A multi-criteria methodology for evaluating alternative ultrasound devices

Area of Science:

• Occupational Health
• Ergonomics
• Medical Device Technology

Background:

• High prevalence of work-related musculoskeletal disorders (WMSDs) affects sonographers.
• Advanced ultrasound devices can exacerbate WMSDs by compromising user comfort.
• Device selection impacts both worker well-being and diagnostic center productivity.

Purpose of the Study:

• To develop a structured methodology for selecting optimal ultrasound devices.
• To balance worker well-being with company production objectives in device procurement.
• To provide a decision-making framework for hospitals and diagnostic centers.

Main Methods:

• Application of the Analytic Hierarchy Process (AHP), a multi-criteria decision-making approach.
• Defined a Goal optimizing worker well-being and production, with 45 evaluation elements.
• Conducted a case study in an Italian hospital comparing wireless, portable, and cart-based ultrasound devices.

Main Results:

• The cart-based ultrasound device was identified as the best option for satisfying the overall Goal.
• A previous study indicated wireless devices were preferable solely from an ergonomic perspective.
• The AHP methodology proved applicable and effective in the case study.

Conclusions:

• The AHP methodology provides a robust framework for selecting ultrasound devices that enhance worker well-being and meet operational demands.
• This approach supports informed purchasing decisions for healthcare facilities.
• Findings can guide ultrasound device manufacturers in product improvement.
