International audience. Choosing the subcutaneous (SC) route of administration of abatacept and tocilizumab is more cost-effective than the intravenous (IV) route. The objective of this study was to examine patients' reasons for choosing to keep with their IV infusions or to switch to subcutaneous SC injections. This study was based upon a self-administered questionnaire given to consecutive rheumatoid arthritis patients treated with abatacept or tocilizumab. Patients were asked to express their opinions concerning reasons explaining why they chose to keep the IV route or switch to the SC route. A total of 201 questionnaires completed by 127 patients treated by tocilizumab and 74 by abatacept were analysed. Overall, 45.8% of the patients chose to keep the IV route of administration. Another ongoing SC treatment was noted more often in patients choosing the SC route (15.9 versus 4.3%, p < 0.05). Reasons guiding the choice of the SC route were concerns about repeated hospital day-care (72%), greater autonomy with SC injections (38.7%) and economic considerations (21.5%). Reasons associated with choosing to maintain the IV route were worries about a lack of follow-up (72.1%), the absence of medical assistance during the SC injection (61.2%), maintaining social relationships with other patients developed at the hospital (40.5%), lower frequency of injection (32.9%), fear of adverse events (27.7%) and fear of SC injections (17.9%). Patients reject the SC switch from the IV route of tocilizumab and abatacept mainly because of fears about the unknown SC route, while those who accept it find it more convenient.
