Estimation of adjusted minimal important differences for hip and knee replacement patients

Project description

One main goal of hip and knee replacements is to improve patients’ health-related quality of life (HRQoL). Thus, to properly assess treatment quality, it is crucial to understand which hip and knee replacements are successful in terms of changes in patient-reported HRQoL.  

A meaningful evaluation of treatment success can be achieved by calculating minimal important differences (MIDs) for changes in patient-reported outcome measures (PROMs). Evidence shows that considering patient characteristics is essential for calculating accurate MIDs.  

With this study we aim at estimating MIDs adjusted for patient characteristics for EQ-5D-3L index score improvements after hip and knee replacements. We contribute to the existing literature by relying on a large national sample and precise clustering algorithms.
