IntroductionHealth technology assessment (HTA) agencies are increasingly embracing patient experience data (PED) to support reimbursement decisions. This study aimed to review HTA agencies’ expectations with regards to utilizing PED to support drug reimbursement in Australia, Japan, and China.MethodsPublished HTA guidance documents were reviewed in 2021 to identify any PED-specific information. If available, recommendations related to the type of PED (e.g., generic vs. disease-specific clinical outcomes assessment (COA)); COA validation, analyses, endpoints and interpretation; and the interest in PED beyond COA in HTA decision-making (e.g., patient preference information) were reviewed. Literature review and semi-structured interviews with key opinion leaders (KOLs) were conducted to further explore these themes and future trends with regards to PED.ResultsAustralia’s Pharmaceutical Benefits Advisory Committee guidance document includes a dedicated section on patient-reported outcomes (PRO), providing details on preferred PRO instruments; validation expectations; and recommended methods to explore score interpretation, assess and report PRO results and handle missing data. While PED derived from non-PRO sources are not discussed in the guidance, the KOL noted that they should not be ruled out. Japan’s Center for Outcomes Research and Economic Evaluation for Health guideline includes a section dedicated to PROs without details related to instrument validation, analyses and interpretation, however, is focused on the use of PRO to inform health economic assessments. In China, the HTA center of China National Health Commission drafted two disease-specific technical guidance documents recommending the inclusion of PROs in efficacy assessments and use of instruments relevant in the Chinese population; these points were echoed by the KOL interviewed.ConclusionsThere are recommendations on PED use included in country-specific guidance documents, however their level of detail varies greatly. 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.
