IDEAL-D Framework for Medical Device Evaluation
The IDEAL-D framework helps improve how medical devices are tested and approved by suggesting a step-by-step process that collects better evidence as the device moves from early use to widespread adoption.
At a glance
Use when
Developing regulatory pathways for novel medical devices, designing clinical evaluation programs, improving post-market surveillance strategies
Avoid when
When regulatory systems lack capacity for adaptive approval, or when real-world data infrastructure is insufficient
Inputs
Device design, preclinical data, clinical study results, real-world performance data
Outputs
Staged regulatory decisions, evidence generation roadmap, recommendations for further evaluation
How it works
IDEAL-D is an extension of the IDEAL (Idea, Development, Exploration, Assessment, Long-term study) framework adapted specifically for medical devices. It proposes a staged, prospective approach to evidence generation across the device lifecycle, supporting graduated regulatory approval based on evolving data from clinical use.
- HTA domains
- Clinical Effectiveness, Safety, Organisational aspects
- Assumptions
- Device performance can be evaluated progressively; early-stage data informs later-stage study design; regulatory flexibility improves patient outcomes
- Strengths
- Supports innovation while ensuring safety, promotes systematic evidence generation, aligns with real-world use patterns, improves transparency
- Limitations
- Requires regulatory flexibility and international coordination, depends on robust post-market data collection, may slow initial adoption
- Also known as
- IDEAL-D, IDEAL for Devices
