Objectives. A discrepancy exists between the National Institute for Health and Clinical Excellence (NICE) guidelines for continuation of TNF therapy in RA and EULAR response criteria. We performed a retrospective study of patients starting anti-TNF therapy to establish how many NICE non-responders would have met EULAR response criteria, and whether this may increase.
Method. We calculated the percentage of NICE non-responders who would have met EULAR moderate response criteria. We then compared the mean decrease in disease activity score (DAS28) for patients with low and high baseline scores. We analysed trends for treating RA in Derby with anti-TNF to address whether we were treating less active disease over time.
Results. At 3 months (n = 271 patients), 7.7% of NICE non-responders would have met EULAR moderate response criteria. At 6 months (n = 240 patients) this was 23.7%. Patients starting with a higher DAS28 had a significantly greater absolute drop in score. The mean decrease between the 1st and 3rd tertiles of patients divided by baseline DAS28 was significant at 3 and 6 months (P < 0.001). Derby rheumatologists were treating less active RA over time. Comparing the mean DAS28 baseline between the 1st and 3rd tertiles of patients divided by anti-TNF commencement date was significant (P < 0.001).
Conclusions. A significant minority of NICE non-responders would fall within the moderate EULAR response criteria. This is likely to increase in future due to the increasing tendency to initiate anti-TNF in patients with less active disease. Consequently, NICE guidelines should be brought in line with EULAR response criteria.
