Health technology assessment (HTA) agencies are increasingly embracing patient experience data (PED) to support reimbursement decisions. This study aimed to describe the European Network for HTA (EUnetHTA) and HTA agencies expectations regarding PED to support reimbursement in France, Germany, Italy, Spain and the UK.

Published HTA guidance documents were reviewed to identify recommendations related to clinical outcomes assessment (COA) (including disease-specificity, validation, analyses, endpoints and interpretation) and other forms of PED (e.g., patient preference information) in HTA decision-making. Insights from guidance documents were supplemented with a review of literature and published HTA cases and interviews with key opinion leaders (KOLs) focused on current and future states.

The German and French guidance documents include PED recommendations focused on relevant COA and health-related quality of life data, without detailing preferred COA measures. However, key differences were noted between these two countries in the methodological approaches regarding responder definitions, acceptable missing data threshold and multiplicity analyses. These differences were reinforced by the case studies and the KOLs. UK’s sources also focused on COA, in general proposing specific use of the EQ-5D to derive utility values for modelling, but included limited details on other PED-related elements. The Italian and Spanish guidance documents do not detail COA or other PED expectations, but the Italian KOL described that COA is considered if submitted. The currently developed EUnetHTA21 guidelines include PED-related information that bear the signature of certain individual HTA bodies. Globally, there is limited interest in PED beyond COA across the agencies.

The level of expectations with regards to PED varies across EUnetHTA and several European HTA agencies. Interest in PED derived from non-COA sources is limited across the countries. Knowing each agency’s expectations with regards to PED is key when submitting HTA evidence dossiers and should be considered early in clinical trial design to integrate market access perspectives and optimize drug development. Global harmonization would help advancing PED measurement standards.
