Implementation of Immunization Services Through a Pediatric Urgent Care Clinic.

Background and objectives: Pediatric urgent care (PUC) centers may bolster immunization campaigns by offering vaccination during acute care visits, but few such programs have been described.

Methods: We conducted a quality improvement initiative at an academically affiliated federally qualified health center that provides primary, specialty, and PUC services to children. Our PUC began offering routine immunizations in July 2020. The percentage of visits by eligible patients age ≤21 years during which immunization screening (process) and administration (outcome) occurred was measured from March 1, 2021, to February 19, 2023. Administration rates were measured across age, sex, race, language, and medical home groups. Data were analyzed with statistical process control methods. Grievance and adverse event data were monitored (balancing).

Results: We completed 4 plan-do-study-act cycles. Provider-facing bundles that included training, decision support, electronic health record signaling, and financial incentives were not associated with meaningful changes in screening and administration (cycles 1-3). A dedicated nurse vaccinator (DNV) was added on October 31, 2022 (cycle 4). The mean screening rate increased from 44.7% to 67.4% during the DNV period, and the mean administration rate increased from 26.5% to 50.8%. Lower administration rates were observed during visits by Black and English-speaking patients, and by patients empaneled outside our site.

Conclusions: Provider-facing interventions alone were not effective at increasing vaccine screening and administration in our PUC, but marked improvement was observed with the addition of a DNV. Future interventions are needed to address disparities. Additional investigation is needed to determine whether our results are reproducible in other PUCs with access to vaccines.
