2. Patient input – ’advocacy’ versus provision of ’evidence’
HTA bodies are not organised according to a single accepted structure, nor is there one standard approach to involving patients in their work. The nature of patient involvement varies depending on the political and cultural context. It should be developed through a partnership between the HTA body and patient representatives, and remain responsive to ongoing experience and feedback.
HTA supports public decision-making—that is, decisions affecting all potential users of the healthcare system. In most health jurisdictions, ministers of health are accountable not only to patients in need of care, but also to the broader tax-paying public that funds the healthcare system.
Health Technology Assessment (HTA) processes are designed to support decision-making by delivering relevant data and analysis within a fair and transparent framework. The ultimate aim is to provide recommendations that guide authorities in decisions such as whether to make a new health technology available to the patients who need it—and under what conditions.

Patient input – ’advocacy’ versus provision of ’evidence’
Patient input in this context is essential. It ensures that the value and impact of a new technology on patients’ lives and well-being are properly considered. As the outcomes of HTA processes can significantly affect patients’ health, it is important that their voices are reflected throughout.
Patient advocacy plays a crucial role by illustrating how and why particular decisions matter to patients. Such input helps decision-makers understand lived experiences and unmet needs, strengthening the transparency and defensibility of the process by incorporating perspectives from those directly affected.
Beyond advocacy, patients should also be actively involved in the HTA process itself—from shaping the research questions to contributing relevant patient outcome and experience data, and participating in the synthesis and appraisal of evidence. This ensures that patient-relevant factors are not just heard, but meaningfully integrated into final recommendations.
A key first step for patients and patient groups is to understand whether, and how, their local HTA processes allow for patient involvement—at which stages and in what capacity. Since HTA structures vary across countries and regions, patients are encouraged to familiarise themselves with national or local HTA procedures to align their contributions with the HTA body’s scope and remit.
Where patients are not actively included, they can examine whether and how patient-relevant outcomes and preferences have been captured and evaluated in the available evidence. In such cases, patient groups may also explore ways to develop or provide population-based research to contribute to these processes—an effort that typically requires early engagement with the HTA body.
Unfortunately, many HTA processes still fall short of these core principles. For instance, a number of HTA committees do not yet include patient representatives who understand the process and can articulate the patient perspective during key phases such as topic definition, assessment, and appraisal.
