Treat-to-target in rheumatoid arthritis: Evaluating the patient perspective using the Patient Opinion Real-Time Anonymous Liaison system: The RA T2T PORTAL study

Objectives: To determine the level of agreement among patients with rheumatoid arthritis (RA) with the principles and recommendations of the treat-to-target (T2T) initiative in New Zealand (NZ) and to further explore specific patient opinions via online iterative surveys. Methods: Participants with RA were recruited from rheumatology clinics in NZ and invited to receive and reply to surveys administered via the Patient Opinion Real-Time Anonymous Liaison (PORTAL) system. An enrolment survey recorded demographics, disease duration and treatment and then RA T2T surveys were administered weekly. A Likert scale 1-5 measured agreement with the principles and recommendations and further surveys explored responses of interest identified by investigators from each prior survey. Results: One hundred and ninety patients consented to participate in PORTAL and 132 in the RA T2T surveys. Level of agreement with RA T2T principles was: 93.3% to 99.3% and to the recommendations: 77.3%-100%. The lowest level of agreement 77.3% was with recommendation 8, 3 monthly treatment adjustment, and the highest was 100% agreement with recommendation 10, shared decision-making. Patients agreed less with low disease activity as the target compared with remission (91.4% and 98%). Despite high-level agreement for the use of a disease activity score (95.7%), 23% did not feel the individual components reflected their disease control. Patients rated difficulty coping, erosions on imaging, health-related quality of life and pain all significantly higher than C-reactive protein as indicators of worsening arthritis. Conclusions: Despite a high level of patient agreement with RA T2T this study highlights the importance of patient engagement in the RA T2T process to individualize therapy adjustments, make shared decisions and decide on targets that accurately reflect disease control according to patients.
