Barriers to treatment adjustment within a treat to target strategy in rheumatoid arthritis: a secondary analysis of the TRACTION trial.

Objectives: Adherence to a treat to target (TTT) strategy is a recommended paradigm for RA; however, research shows there are many barriers to implementation. We conducted a trial to improve TTT implementation, and herein examine barriers to treatment adjustment within TTT among patient visits not in agreement with the TTT paradigm.

Methods: Chart review assessed TTT implementation based on documentation of four items: designation of a treatment target, recording a disease activity measure, shared-decision making when applicable and adjusting treatment when disease activity was not at target. A treatment decision not in agreement with the TTT paradigm was defined as lack of treatment adjustment when disease activity was not at the pre-determined treatment target. Providers were encouraged to report the barriers to treatment change; these were categorized and analysed by study staff. Multiple barriers were possible for one visit.

Results: Eighty-three visits not in agreement with the TTT strategy were observed in 74 patients, during which 90 reported barriers to treatment adjustment were noted. Common barriers to adjusting treatment included patient preference in 37.1% of visits and elevated disease activity measure despite no objective evidence of active RA in 38.6% of visits.

Conclusion: An elevated disease activity measure not reflective of RA disease activity and patient preference are the two leading barriers to treatment adjustment to TTT in RA. Understanding barriers to adherence should guide interventions aimed at using better markers of disease activity and improving alignment with patient preference, with the overarching goal of enhancing TTT adherence.
