Three-Domain Impact Framework for patient involvement in HTA
The Three-Domain Impact Framework helps assess how patient involvement affects health technology assessment. It looks at changes in assessment outcomes, the HTA organization itself, and the experiences of the patients who took part. This helps HTA bodies understand and improve how they include patients.
At a glance
Use when
Evaluating or reporting the impact of patient involvement in HTA; designing patient engagement strategies with impact tracking; improving transparency in stakeholder engagement practices.
Avoid when
When only quantitative, outcome-based metrics are required; when a detailed process evaluation (rather than impact) is the goal; when resources for qualitative data collection are unavailable.
Inputs
First-hand qualitative accounts from patient representatives, HTA bodies, and industry stakeholders; structured questionnaire responses on perceived impacts of patient involvement.
Outputs
A structured framework with three domains and subcomponents for reporting and evaluating the impact of patient involvement in HTA.
How it works
Developed by the Patient and Citizen Involvement in HTA Interest Group (PCIG) within HTA International, the framework emerged from qualitative analysis of 24 first-hand accounts collected between 2019 and 2021. Using thematic analysis of responses from patient representatives, HTA bodies, and industry across multiple regions, the framework identifies three domains of impact: (1) impact on the basis of HTA results or recommendations, (2) impact on the HTA body, and (3) impact on patient participants. Each domain includes measurable components to support systematic reporting and evaluation of patient involvement in HTA processes.
- HTA domains
- Clinical Effectiveness, Organisational aspects, Patient and Social Aspects
- Categories
- AppraisalContext & Implementation
- Assumptions
- Patient involvement leads to meaningful changes in HTA processes and outcomes; stakeholders can reliably report perceived impacts; impact can be categorized and communicated using a common framework.
- Strengths
- Developed through international, multi-stakeholder input; addresses gaps in current evaluation practices by moving beyond process metrics; supports transparency and cross-jurisdictional learning; includes impact on patients themselves, not just institutional outcomes.
- Limitations
- Based on self-reported perceptions rather than objective metrics; limited sample size (n=24); may not capture all forms of impact; not yet validated through widespread implementation.
- Also known as
- Three-Domain Impact Framework, 3-Domain Impact Framework, PCIG Impact Framework
