A substantial number of patients with rheumatoid arthritis (RA) have multiple comorbidities, and these were associated with poor health-related qualify of life (HRQoL) and higher health care expenditures, a new study found. Adult patients with RA and age-, sex-matched individuals without RA (non-RA controls) were identified from the Medical Expenditure Panel Survey 2010-2015 data. 20 comorbidities were investigated. Researchers found:
- A total of 2,925 patients with RA and 14,625 controls were included.
- Approximately 60.4% of RA and 37.2% of non-RA had ≥3 comorbidities, and 23.5% of RA and 12.0% of non-RA controls had ≥5 comorbidities.
- The prevalence of comorbidities in RA was higher across different types of comorbidities vs non-RA controls.
- The most prevalent comorbidities in RA were cardiovascular diseases (79.0%) followed by respiratory conditions (34.4%).
