Background/Purpose: Telemedicine (TM) has been widely advocated and used to follow up patients with rheumatic diseases during the COVID-19 outbreak. However, there is no evidence supporting its use in systemic lupus erythematosus. We aimed to evaluate the short-term patient satisfaction, compliance, disease control and infection risk of TM compared with standard in-person follow-up (FU) for patients with lupus nephritis (LN) during the pandemic.

Methods: This was a single-center open-label randomized controlled study. Consecutive patients followed at the LN clinic were randomized to either TM or standard FU (SF) group in a 1:1 ratio. Patients in the TM group received FU via videoconferencing. SF group patients continued conventional in-person outpatient care. The 6-month data were compared and presented.

Results: From June to December 2020, 122 patients were randomized (TM: 60, SF: 62) and had at least 2 FUs. There were no baseline differences, including SLEDAI-2k and proportion of patients in lupus low disease activity state (LLDAS), between the 2 groups except a higher physician global assessment score (PGA) in the TM group (table). After a mean FU of 19.8±4.5 weeks, the overall patient satisfaction score was higher in the TM group with a significantly shorter waiting time from entering the clinic waiting room (virtual or real) to seeing a rheumatologist (figure). More patients in the TM group had hospitalization (15/60, 25.0% vs 7/62, 11.3%; p=0.049) with higher baseline PGA (OR=1.15, 95% CI 1.07-1.23) being the independent predictor. The proportions of patients remained in LLDAS were similar in the 2 groups (TM: 75.0% vs SF: 74.2%, p=0.919). None of the patients had COVID-19.

Conclusion: TM FU resulted in better patient satisfaction and similar short-term disease control in patients with LN compared to standard care. However, it was associated with more hospitalizations and might need to be complemented by in-person visits especially in patients with higher PGA.
