The Patient Activation Measure in Patients with Rheumatoid Arthritis: A Systematic Review and Cross-Sectional Interview-Based Survey

Introduction/objective: The patient activation measure (PAM) is considered a reliable tool for measuring patient activation. This study aimed to systematically review the scientific literature regarding the use of PAM -13 in rheumatology patients and to compare PAM scores in patients with rheumatoid arthritis (RA) following two different practices at a single institution with previously published studies.

Methods: The study consisted of a systematic review of articles reporting the PAM-13 in patients with RA, followed by a cross-sectional study evaluating PAM scores between standard rheumatology clinics and specialized rheumatology clinics (SRCs). The correlation between PAM levels and other variables, such as demographics, disease characteristics, and treatment, was assessed.

Results: Nineteen studies, published between 2012 and 2022, met the inclusion criteria. The studies in this review had inconsistent results and quality, with patient activation in RA ranging from 29 to 76. A total of 197 patients with confirmed RA diagnoses were interviewed (response rate, 88%). Most were female (n=173, 88%) and older than 40 years (n=150, 76%). The average patient activation score was 64.9 (standard deviation, 15.7). Most participants had level 3 and 4 patient activation measures (n=71 [36%] and n=72[37%], respectively). Patients who were attending SRCs also had borderline higher PAM levels. Patients with high PAM scores tended to be older, have active disease, and were taking corticosteroids.

Conclusion: Adequate activation of patients was observed from our center, which was higher than that reported in most published literature. The PAM of patients with RA was variable according to the systematic review. Longitudinal interventional studies should be considered to improve activation in patients with low scores.
