Evidence requirements for innovative imaging devices: from concept to adoption

Area of Science:

• Medical Imaging
• Health Economics
• Regulatory Science

Background:

• The US regulatory and reimbursement landscape for medical imaging is evolving.
• There's a growing demand for robust clinical evidence demonstrating efficacy, effectiveness, and safety of imaging innovations.

Purpose of the Study:

• To outline the five phases of an imaging product's lifecycle.
• To identify the distinct clinical evidence needs at each lifecycle phase.
• To explore the implications of evidence generation costs and responsibilities.

Main Methods:

• The authors describe a five-phase model for imaging product development.
• Analysis of clinical evidence requirements throughout the product lifecycle.
• Discussion of the challenges posed by the pace of technological advancement versus evidence generation timelines.

Main Results:

• Imaging product lifecycles include design, regulatory approval, early adoption, reimbursement, and full adoption.
• Each phase necessitates specific types of clinical evidence.
• A significant gap exists between rapid technological progress and the time needed for formal clinical trials.

Conclusions:

• The increasing cost and complexity of generating clinical evidence pose challenges to innovation adoption.
• The mismatch between technology development and evidence requirements risks limiting patient access to beneficial imaging advancements.
• Careful consideration of public and payer evidence demands is essential for future diagnostic imaging improvements.
