Abstract
INTRODUCTION: This pragmatic non-inferiority study assessed quality of care within a nurse-led care (NLC) model for stable patients with rheumatoid arthritis (RA) compared to the traditional rheumatologist-led care (RLC) model. METHODS: Data were collected through a chart review. Baseline demographic and clinical characteristics were compared using Chi-square test and t test. The primary outcome measure was the percentage of patients being in remission or low disease activity (R/LDA) with the Disease Activity Score (DAS-28) ≤ 3.2 at 1-year follow-up. Process measures included the percentages of patients with chart documentation of (1) comorbidity screening; (2) education on flare management, and (3) vaccinations screening. Outcomes were summarized using descriptive statistics. RESULTS: Each group included 124 patients. At baseline, demographic and clinical characteristics were comparable between the groups for most variables. Exceptions were the median (Q1, Q3) Health Assessment Questionnaire Disability Index scores [0 (0, 0.25) in NLC and 0.38 (0, 0.88) in RLC, p = 0.01], and treatment patterns with 3% of NLC and 38% of RLC patients receiving a biologic agent, p = 0.01. NLC was non-inferior to RLC with 97% of NLC and 92% of RLC patients being in R/LDA at 1-year follow-up. Patients in the NLC group had better documentation across all process measures. CONCLUSIONS: This study provided real-world evidence that the evaluated NLC model providing protocolized follow-up care for stable patients with RA is effective to address patients' needs for ongoing disease monitoring, chronic disease management, education, and support.
