Treatment delays for patients with new-onset rheumatoid arthritis presenting to an Australian early arthritis clinic.

Abstract

Early treatment ensures optimal outcomes in rheumatoid arthritis (RA) yet there are limited data in Australia quantifying treatment delays in clinical practice. To quantify treatment delays in new RA patients and to explore factors influencing delay and resultant patient outcomes. Data were obtained for 88 patients presenting with a new diagnosis of RA to an early arthritis clinic (EAC) in Australia between 2008 and 2015. Date and details of symptom onset, initial general practitioner (GP) presentation, GP referral and review at EAC were collected. Patient demographics and clinical features were analysed for outcomes and features predictive of delay. Median overall delay from symptom onset to rheumatology review was 26.4 weeks. Patient delay (8.7 weeks) was the longest delay and predicted overall delay. Delays in GP referral and time to EAC review were 4 and 8.4 weeks respectively. Increased overall delay was predicted by lower fatigue and disease activity scores (DAS28) and increased tender joint counts (TJC). Patient delay was increased by socioeconomic disadvantage. Increased GP delay was associated with lower DAS28 and higher TJC and ESR. Patients seen within 16 weeks had greater improvement in DAS28 and probability of remission at 6 months. In this Australian EAC setting, patient delay was the greatest contributor to RA treatment delay. Delays in treatment were associated with lower disease severity and socioeconomic disadvantage. Remission was more likely after prompt initiation of treatment.
