Objective To compare the relative effectiveness of anti–tumor necrosis factor (anti‐TNF) therapies on health‐related quality of life (HRQOL) by inflammatory arthritis types. Methods Patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS), and psoriatic arthritis (PsA) who had anti‐TNF therapy (etanercept, adalimumab, or infliximab) in the Australian Rheumatology Association Database during 2001–2011 were assessed using the Medical Outcomes Study Short Form 36 (SF‐36), Assessment of Quality of Life (AQoL), and Health Assessment Questionnaire (HAQ) disability index (DI) on a biannual basis. Linear regression was used for the analysis; the lack of independence in outcomes for multiple assessments in the same patient was taken into account using generalized estimating equations. Results There were 18,119 assessments (first‐time drug use n = 12,274, subsequent use n = 3,098, and no use n = 2,747) provided by 3,033 patients (2,240 RA, 507 AS, and 286 PsA patients) with the anti‐TNF therapies. The effects of subsequent use versus first‐time use were reduced on the SF‐36 physical component summary, AQoL, and HAQ DI scores among RA patients. After adjusting for therapy order, calendar year, sex, age, smoking status, and various medication uses, the 3 anti‐TNF preparations had similar effects on the HRQOL measures for patients with RA, AS, or PsA. However, differences between anti‐TNF therapies were observed in the AQoL score among PsA patients (infliximab versus etanercept: −0.06 [95% confidence interval (95% CI) −0.12, −0.004]) and in the SF‐36 mental component summary score among RA patients (adalimumab versus etanercept: −1.17 [95% CI −1.88, −0.46]). Conclusion This study revealed similar effectiveness of etanercept, adalimumab, and infliximab on the HRQOL measures among Australians with RA, AS, and PsA.
