Abstract
OBJECTIVES: Asthma exacerbations are a leading cause of hospitalization among children. Despite the existence of hospital protocols and national guidelines, little guidance is available regarding appropriate short-acting β-agonist (SABA) frequency discharge criteria. Our aim was to reduce the median length of stay (LOS) for children hospitalized with asthma exacerbations by 4 hours by changing the discharge requirement SABA frequency. METHODS: Multiple plan-do-study-act cycles based on findings in our key driver diagram were used to decrease LOS. Our primary intervention was reducing the SABA administration frequency discharge requirement from every 4 hours to every 3 hours. After a feasibility pilot, this change was implemented throughout the hospital. Our intervention bundle included updating our evidence-based guidelines, electronic health record order sets and note templates, house-wide education, and a new process for respiratory therapists to notify physicians of discharge readiness. Our primary metric was LOS, with 3-, 7-, and 14-day same-cause emergency department (ED) revisits and hospital readmissions as balancing metrics. Statistical process control charts and nonparametric testing were performed for data analysis. RESULTS: Median hospital LOS was significantly lower in the postintervention period compared with the preintervention period (30.18 vs 36.14 hours respectively; P < .001). Statistical process control charts indicated special cause variation was achieved. No significant differences were observed in rates of ED revisits or hospital readmissions. CONCLUSIONS: Reducing the discharge requirement of SABA frequency from every 4 hours to every 3 hours resulted in a reduction in LOS, with no increase in ED recidivism or hospital readmission rates.
