Impact of a pharmaceutical care service for patients with rheumatoid arthritis using a customised mobile device (the PROUD trial): study protocol for a randomised controlled trial

Abstract

IntroductionRheumatoid arthritis (RA) generally requires lifelong treatment; however, its medication complexity might affect non-adherence. Pharmacist-led telehealth services were as effective as face-to-face services and reduced potential side effects in outpatients with chronic diseases. This study aims to analyse the effect of a telepharmacy service with a customised mobile device in comparison with the usual pharmacist service on the humanistic and clinical outcomes in patients with RA.Methods and analysisThe study is designed as a prospective, randomised, open-label, and controlled trial to compare the humanistic and clinical outcomes of the pharmaceutical care service with monthly telecommunications and a customised mobile application (telepharmacy care group) against the usual service by community pharmacists (usual care group) in 256 patients with RA and prescribed at least one of the disease-modifying antirheumatic drugs. Participants will be recruited from a tertiary hospital in Republic of Korea with written informed consent. The primary outcome will be the changes in health-related quality of life as measured by the Korean version of the EuroQoL’s five-dimensional questionnaire at 6 months compared with baseline. The secondary outcomes will be the changes in the following: scores of the Korean version of the Compliance Questionnaire-Rheumatology and medication knowledge at 3 and 6 months compared with baseline; scores of the Korean version of the Pharmacy Service Questionnaire at 6 months compared with baseline; clinical parameters such as erythrocyte sedimentation rate, C reactive protein level, and pain score at 3 and 6 months compared with baseline; frequency of acute care utilisation over 6 months. Analysis will be carried out with intent-to-treat and per-protocol principles.Ethics and disseminationThe study protocol was reviewed and approved by the Institutional Review Board (IRB) of Daegu Catholic University Medical Center (IRB no. CR-21-082-L, 14 July 2021). The study findings will be published in peer-reviewed journals.Trial registration numberKCT0006508.
