BackgroundMediastinal masses in children may present with compression of the great vessels and airway. An interdisciplinary plan for rapid diagnosis, acute management, and treatment prevents devastating outcomes and optimizes care. Emergency pretreatment with steroids or radiation is more likely to be administered when care is variable, which may delay and complicate diagnosis and treatment. Strategies to standardize care and expedite diagnosis may improve acute patient safety and long-term outcomes.AimsThe aim of this quality improvement project was to decrease time from presentation to diagnostic biopsy for children with an anterior mediastinal mass by 50% over 3 years within a tertiary healthcare system.MethodsThis quality improvement project involved a single center with data collected and analyzed retrospectively and prospectively for 71 patients presenting with anterior mediastinal mass between February 2008 and January 2018. The Model for Improvement was utilized for project design and development of a driver diagram and smart aim. An algorithm was implemented to facilitate communication between teams and standardize initial care of patients with mediastinal masses. The algorithm underwent multiple Plan-Do-Study-Act (PDSA) cycles. Data were collected before and after algorithm implementation and between each PDSA cycle. The primary outcome measure included time from presentation to biopsy, which was monitored with a statistical process control chart. Several process measures were evaluated with Student's t-tests including administration of emergency pretreatment.ResultsNineteen patients preintervention and 52 patients postintervention were included in the analysis. Time from presentation to biopsy significantly decreased from 48 h at baseline to 24 h postimplementation. Although not statistically significant, emergency pretreatment decreased from a baseline of 26.3% to 6.7% postimplementation.ConclusionImplementation of a diagnostic and management algorithm coordinating care among multidisciplinary teams significantly reduced time to biopsy for children presenting with mediastinal mass and may result in decreased use of emergent pretreatment.© 2021 John Wiley & Sons Ltd.
