Objective: To assess for improvement in diagnostic efficiency following implementation of an institutional pediatric stroke alert protocol at a quaternary children's hospital, and to compare characteristics of in-hospital (IH) and out-of-hospital (OH) stroke alert activations.
Study Design: We retrospectively reviewed data from pediatric stroke alerts called for children between age 1 month and 21 years of age at our quaternary children's hospital between October 2016 and October 2022 after implementation of an institutional stroke alert protocol. Generalized linear models assessed code-to-image (CTI) time over the study period, with and without interaction terms for alert location. Demographic, clinical, and imaging characteristics between IH and OH alerts were compared using Fisher's exact test or Mann-Whitney U test.
Results: Of 206 total stroke activations, 129 (62.6%) occurred IH and 77 (37.4%) occurred OH. Overall mean CTI time decreased by 4.56 minutes per year (P = .007) after adjusting for confounders. The association between year and mean CTI time was significantly stronger for IH alerts (decrease of 8.33 minutes/year) compared with OH alerts (increase of 1.90 minutes/year). Subgroup analyses showed that CTI for computed tomography (CT) ± CT angiography and magnetic resonance imaging (MRI) without sedation improved, although CTI time for MRI with sedation did not change over time. IH/OH divergent trends were consistent for CT ± CTA and nonsedated MRI.
Conclusions: After implementation of a pediatric stroke alert protocol, we observed a steady and significant improvement in CTI times for IH, but not OH alerts.

Background: Children presenting to the pediatric emergency department (PED) with neurologic dysfunction require prompt evaluation. Many PEDs successfully implement stroke alerts. However, most pediatric patients presenting with neurologic dysfunction have a non-stroke diagnosis better evaluated using magnetic resonance imaging (MRI).

Background: Acute ischemic stroke with medium and large vessel occlusion is a leading cause of morbidity and mortality, in which timely intervention with mechanical thrombectomy (MT) is crucial for restoring cerebral blood flow and improving patient outcomes. Effective analgosedation and hemodynamic management during MT are critical to patient outcomes and typically managed by anesthesia. Because of inconsistent anesthesia support at our institution, we implemented a dedicated neurocritical care rapid response team (NCC-RRT) to manage these aspects of care.

Background: Timely recognition of acute ischemic stroke (AIS) is essential to identify patients who may be eligible for acute intervention. Protocols to streamline systems-based care, such as "stroke alerts" in the emergency department (ED) can safely reduce time-to-care while enhancing safety. However, clinician adherence to stroke alert criteria is poorly described.
