Blinatumomab infusion interruptions in pediatric patients rarely lead to readmission.

Blinatumomab is a bispecific T-cell engager administered as a 28-day continuous infusion. Infusions can be associated with interruptions requiring support from clinical staff, but the frequency of interventions with outpatient blinatumomab has not been characterized. This study is a single-center, retrospective review of patients who received blinatumomab between December 3, 2014 and October 31, 2021 to determine frequency and type of interventions. Forty patients received blinatumomab for 69 cycles. Clinical staff intervention was required in 31 (45%) cycles, only six (8.7%) cycles needed readmission. Management of outpatient blinatumomab infusions requires education and training of clinical staff and caregivers to quickly troubleshoot interruptions.
