App aids self-monitoring of some rheumatoid arthritis patients

Patient-initiated care supported with smartphone self-monitoring is noninferior to usual care for rheumatoid arthritis (RA) in patients with stable low disease activity, according to a study published online July 11 in Arthritis & Rheumatology.

Bart Seppen, M.D., from Reade Rheumatology in Amsterdam, and colleagues assessed the safety and efficacy of a smartphone app for patients with RA, which allows them to self-monitor their disease activity in between clinic visits. The analysis included 102 patients randomly assigned to either app-supported patient-initiated care with a scheduled follow-up consultation after a year (app group) or usual care.

The researchers found that after a year, noninferiority of the disease activity score 28 (DAS-28) was established with the mean ΔDAS-28 between the groups within the noninferiority limit: −0.04 in favor of the app group (95 percent confidence interval, −0.39 to 0.30). In the app group, the number of rheumatologist consultations was significantly lower (visit ratio: 0.62; 95 percent confidence interval, 0.47 to 0.81).
