OBJECTIVES: The prevalence of depression in patients with rheumatoid arthritis (RA) is estimated to be 3.5 times that of the general population and even higher than those with other chronic diseases. However, in Korea, there is still unmet needs in nation-wide data. Thus, this study aims to explore the prevalence of depression in patients with RA according to various definitions of depression and RA severity using the Health Insurance Review and Assessment service (HIRA) claims database in 2014 METHODS: RA patients were defined as adults (≥Depression was defined according to ICD-10 codes of F06.32, F31.3, F31.4, F32, F33, F34.1, F38.1 and F41.2. RESULTS: Overall, 13,462 RA patients were identified from 2014 HIRA-NPS data. By multiplying this figure by inverse sampling probability for each patient, the total number of adult RA patients in the nation was estimated to be 448,688. The prevalence of depression among RA patients ranged from 14.1% to 16.5% depending on the operational definition for depression. RA patients with at least one hospitalization had about 1.53 times higher chance of experiencing depression than those without hospitalization (25.1% vs.16.4%). Patient characteristics seemed to be associated with depression. For instance, female had a higher rate of depression (17.8%) than male patients (13.0%). Patients enrolled in Medicaid (33.7%), which is a public assistance program, tended to experience depression more than those enrolled in National Health Insurance (15.5%), which is a mandatory contributory health security program. CONCLUSIONS: The prevalence rate of depression in RA patients in Korea is high and can vary depending on patient characteristics and disease severity, suggesting that more attention to depression in RA patients is necessary.
