Insights from a Danish nationwide implementation of patient-reported outcomes in multiple sclerosis.

BACKGROUND

Multiple sclerosis (MS) monitoring often relies on traditional methods like the expanded disability status scale (EDSS) and magnetic resonance imaging, which may not fully reflect patients' health. Patient-reported outcomes (PROs) provide valuable insights into patients' experiences of their disease.

OBJECTIVES

This study evaluated the Danish implementation of PROs for people with MS (PwMS) 3 years post-launch, comparing clinical and demographic characteristics between PRO users and non-users, and assessing PRO adherence.

RESULTS

As of 1 January 2025, 2121 PwMS had signed up for PRO, compared to 14,125 who did not. PRO users were younger (mean age 50.6 vs. 53.2 years), more frequently female (73.6% vs. 68.0%), had a shorter disease duration (15.1 vs. 16.4 years), and were more likely to be on high-efficacy disease-modifying therapies (75.6% vs. 62.2%). Additionally, fewer PRO users had low EDSS scores (<3, 53.7% vs. 56.1%) and high scores (>6, 16.5% vs. 18.9%). Most enrolled patients lived in Region Hovedstaden (75.1%).

CONCLUSION

The study highlights differences in profile between PRO users and non-users, demonstrating the PRO platform's adaptability across different ages and disability levels in PwMS. However, these findings also highlight potential implementation challenges and emphasize the need for sustained commitment to support long-term use of PRO.
