Chronic pediatric rheumatologic conditions are characterized by flares and remission. They can require (a) complex medication regimens, often administered via injections or intravenously, (b) frequent disease and medication toxicity monitoring via venipuncture, and (c) visits to the hospital or emergency department. Patients may experience these medical events as traumatic. Medical potentially traumatic events (PTEs) can have adverse effects on the psychological well-being of patients with chronic disease. To date, there is limited knowledge about medical PTEs and their effects on patients with chronic pediatric rheumatologic conditions. To address this gap, we will leverage existing data from a large survey project co-developed with patients and caregivers that assessed mental health needs and incorporated trauma date not previously utilized.
