Discontinuation (most common non-persistent pattern) — Discontinuation, overall
55%
Switch to a different immunosuppressant — Switch, overall
17%

Discontinuation (most common non-persistent pattern) · 12-month follow-up

Highest with mycophenolate, lowest with azathioprine

Switch to a different immunosuppressant · 12-month follow-up

Highest with belimumab

Time to discontinuation or switch

Average time to discontinuation over 3 months
Average time to switch about 5 months
Azathioprine tended to shorter and belimumab to longer times to discontinuation or switch

Predictors of non-persistence (overall sample)

Care by rheumatologists vs primary care and higher co-morbidity (CCI) associated with non-persistence
Race, number of SLE-related medications, census region, sex and age not significantly related to non-persistence
