Do Patients With Intersectional Disadvantage Have Poorer Outcomes From Osteoarthritis Management Programs? A Tapered Balancing Study of Patient Outcomes From the Good Life With Osteoarthritis in Denmark Program
Authors' conclusion
Outcome inequalities widened following OAMP attendance, particularly at longer-term follow-up, but the magnitude of differences was generally modest and inconsistent across outcome measures.
Study context
- Population
- Consecutive knee osteoarthritis (OA) attendees of the GLA:D OA management program in Denmark
- Participants
- 18,448 eligible participants
- Exposure
- Nonnative/foreign citizens with lower education vs native Danish citizens with higher education attending GLA:D
- Intersectional disadvantagen = 250
- Outcome
- Pain intensity, KOOS quality of life subscale score and EQ-5D-5L score
- Follow-up
- 3 and 12 months
Methodological detailsentropy balancing (tapered balancing), weighted linear regression
- Entropy balancing (tapered balancing)
- Weighted linear regression

Further findings
Determinants of outcome inequalities
- Balancing for baseline score, comorbidity, self-efficacy and depression had the greatest effect on reducing observed outcome inequalities
