Disease Activity and Transition Outcomes in a Childhood-onset Systemic Lupus Erythematosus Cohort

Authors: Son MB, Sergeyenko Y, Guan H, Costenbader KH

Summary: Dr. Son collaborated with adult rheumatologists at the Brigham and Women’s Hospital to study patients with childhood-onset lupus who transitioned medical care from a pediatric to adult rheumatologist. The research team identified that there are often gaps in care for patients changing providers. Patients also experience increased negative emotion during the transition. This work highlights the importance of making smooth transitions from pediatric to adult providers.
