OBJECTIVES: Treatment satisfaction is a crucial factor in assessing medical intervention efficacy because it reflects both clinical outcomes and patient experience. Patient-reported outcome (PRO) measures of treatment satisfaction can assess patient perceptions of effectiveness, convenience, and impact of medical treatments. They are increasingly being used outside of clinical settings for self-management, shared decision-making, and research. They play a critical role in research, especially in real-world evidence, health economics and outcomes research (HEOR), and clinical trials, in assessing whether treatments align with patient needs and expectations with minimal harm. However, existing PRO measures vary greatly in scope, reliability, and applicability across conditions. The objective of this research was to develop a new, adaptable PRO measure of treatment satisfaction with clear scoring, subscales adaptable for specialized treatment components, timeframes, side effects, and outcomes, and improved responsiveness.
METHODS: Of 69 PRO measures identified in a search of the literature, only four were generic. Concerns have been noted for all four, including issues with content validity, change detection (i.e., responsiveness), adaptability, scoring complexity, and applicability to specialized treatments. To enhance PRO collection of treatment satisfaction data, we developed a new treatment satisfaction battery with adaptable subscales and clear response scales and scoring.
RESULTS: This scale is currently undergoing pilot testing. Results from testing will be available for presentation at ISPOR Europe 2025.
CONCLUSIONS: Despite their importance in HEOR research, existing PRO measures of treatment satisfaction raise concerns specific to scope, reliability, and applicability across conditions. This study offers an alternative that supports timeline and subscale adaptation to suit specialized treatments and conditions.
