OA04 Association of clinical and demographic factors with quality of life, functional status, depression, and fatigue in patients presenting with, and at risk of, rheumatoid arthritis

Abstract

Abstract Background/Aims Rheumatoid arthritis (RA) is often preceded by symptomatic phases during which classification criteria are not fulfilled. The health burden of these “at-risk” stages is not well described. This study assessed health-related quality of life (HRQoL), functioning, fatigue and depression in newly presenting patients with clinically suspect arthralgia (CSA), unclassified arthritis (UA) and RA. Methods Cross-sectional analysis of baseline Patient-Reported Outcome Measures (PROMs) was conducted in 838 patients with CSA, UA or RA recruited to the Birmingham Early Arthritis Cohort. HRQoL, function, depression and fatigue at presentation were assessed using EQ-5D, HAQ-DI, PHQ-9 and FACIT-F, respectively. Descriptive statistics and multivariate linear regression were performed to assess associations between clinical/demographic variables and PROMs. Results Patients with RA at initial presentation had worse PROMs than those with CSA or UA. However, HRQoL was decreased in all groups. In patients with CSA/UA, HRQoL was comparable to data relating to chronic conditions such as heart failure, severe COPD or mild angina from the Health Survey for England (HSE). Associations between predictor variables and PROMs are summarised in Table 1. Increased functional disability was associated with female sex, older age, obesity, lower quintiles of social deprivation, increased disease activity and polypharmacy. HRQoL was associated with increased disease activity and polypharmacy. The severity of depression (PHQ-9) increased with older age, increasing BMI, living in areas with the lowest quintile of social deprivation, increased disease activity and polypharmacy. Fatigue (FACIT-F) was associated with female sex, increasing BMI, disease activity and polypharmacy. After adjusting for the demographic and clinical factors, the diagnosis assigned at baseline did not affect any of the studied PROMs, but disease activity and polypharmacy were strongly linked to poorer scores across all PROMs. Conclusion Patients with musculoskeletal symptoms who are at risk of RA present with a high health burden. Early intervention may be needed to improve quality of life from initial presentation. Disclosure B. Torlinska: Corporate appointments; BT is employed by Visible Analytics Ltd..
