BACKGROUND: Inclusion of patient experience (PEx) in health technology assessment (HTA) has become increasingly important; however, no harmonized approach exists to help manufacturers or decision makers ensure PEx considerations are fair, consistent, and thorough within global HTA frameworks. OBJECTIVE: To develop a proposal for including PEx in the HTA frameworks of health technologies. METHODS: A systematic literature review (SLR) on existing value frameworks (VFs) was conducted to capture how PEx-related value judgment is currently considered. Guided by the results of the SLR, a research group including HTA experts and patient representatives used an iterative process to develop potential value domains to capture PEx, in accordance with international guidelines. Subsequently, a panel of international payer experts was used to challenge the proposed PEx domains and provide recommendations for implementation. RESULTS: The SLR found 61 VFs and multi-criteria decision analyses (MCDAs) that considered PEx; however, PEx-related value elements were often referred to superficially, without clear definitions. Five potential PEx domains, with proposed measures for each, were developed and refined using expert feedback: (1) responsiveness to patient's individual needs, (2) improved health literacy and empowerment, (3) patient and caregiver reported outcomes, (4) household's financial burden, and (5) improved access for vulnerable patient populations. A flexible approach for framework implementation was proposed. CONCLUSIONS: Proposed PEx domains could be implemented at multiple levels of healthcare decision making to formalize consideration of PEx in the assessment of value, either through the extension of existing VFs or to create new PEx-focused VFs and more holistic decision making tools.
