Prolonged METHODS: durations often prompt admission for ongoing observation. Divisions of aAllergy/Immunology and bPediatric Emergency Medicine and cOffice of Clinical Quality Improvement, In a multidisciplinary quality improvement initiative, we revised Children’s Hospital of Philadelphia, Philadelphia, our emergency department (ED) anaphylaxis clinical pathway. Our primary Pennsylvania aim was to safely decrease the recommended length of observation from 8 Dr Lee conceptualized and designed the study, to 4 hours and thereby decrease unnecessary hospitalizations. Secondary conducted data analysis and interpretation, and aims included provider education on anaphylaxis diagnostic criteria, drafted the initial manuscript; Ms Rodio acquired data, supervised improvement interventions, and emphasizing epinephrine as first-line therapy, and implementing a practice reviewed and revised the manuscript; Drs Lavelle, of discharging ED patients with an epinephrine autoinjector in hand. The Tsarouhas, and Brown-Whitehorn supervised all study period consisted of the 18 months before pathway revision (baseline) aspects of the study, including conceptualization RESULTS: and design of the study, interpreted data, and and the 18 months after revision. P reviewed and revised the manuscript; Ms Lewis The overall admission rate decreased from 58.2% (106 of 182) and Ms Molnar conceptualized and designed the in the baseline period to 25.3% (65 of 257) after pathway revision ( < study, conducted data analysis, and reviewed and revised the manuscript; Ms English and Ms Hadley .0001). There was no significant difference in the percentage of patients coordinated and developed tools for data collection returning to the ED within 72 hours, and there were no adverse outcomes and reviewed and revised the manuscript; Ms or deaths throughout the study period. After pathway revision, the median Zielinski helped conceptualize the study, conduct improvement interventions, and reviewed and time to first epinephrine administration for the most critical patients was revised the manuscript; Drs Jacobstein, Cianferoni, 10 minutes, and 85.4% (164 of 192) of patients were discharged with an and Spergel helped analyze and interpret data CONCLUSIONS: epinephrine autoinjector in hand. and reviewed and revised the manuscript; and all authors approved the final manuscript as By revising an anaphylaxis clinical pathway, we were able to submitted. streamline the care of patients with anaphylaxis presenting to a busy DOI: https:// doi. org/ 10. 1542/ peds. 2017- 1616 pediatric ED, without any compromise in safety.
