Patient-reported quality of life and working status outcomes in ambulatory patients with idiopathic inflammatory myopathy
Authors' conclusion
Multiple disease characteristics were associated with reduced HR-QoL or working productivity impairment in patients with IIM, especially for PtGA.
Study context
- Population
- Ambulatory patients with idiopathic inflammatory myopathy (IIM) (60% DM, 13% PM, 27% clinical amyopathic DM), recruited May 2019 to May 2022
- Participants
- 189 patients
- Outcome
- Health-related quality of life (HR-QoL) (EQ-5D) and work productivity and activity impairment (WPAI), and associated factors
Methodological detailsobservational, quantile regression, ordinal logistic regression
- Observational
- Quantile regression
- Ordinal logistic regression
Main finding
As reported in the abstract
- Median EQ-5D score
- 1.00 (95% CI 0.73, 1.00)
- Employed
- 28%
- Overall work impaired due to health problems
- 45%
- Increased PtGA associated with increased activity and overall working productivity impairment in most quantiles
- P<0.05
Observational data: associations, not effects.
