Creating a leaner pediatric emergency department: how rapid design and testing of a front-end model led to decreased wait time.

Objective: To use Lean methodologies and the Model for Improvement to rapidly redesign and pilot test a new pediatric emergency department (ED) front-end model that reduces time to a licensed independent provider to 30 minutes or less.

Methods: Lean improvement methodologies were applied during a 5-day multidisciplinary model of care redesign event. The new ED front-end model of care included: (1) placement of a registered nurse in the lobby; (2) direct patient rooming with elimination of traditional triage; 3) early documentation of home medications; 4) Team-based immediate assessment; 5) "early Initiation" providers to place orders when a team was not available. An observational, cohort controlled before-and-after study design was used. The new model was tested over 2 pilot periods and compared to a similar period of control days, defined as the "current state."

Results: The ED census and patient acuity were similar during both pilot periods. Eighteen patients were included in pilot 1, and 80 patients were included in the expanded second pilot. Patients seen within 30 minutes improved from a baseline of 33% to 93% in pilot 2. Time to a licensed independent provider, to a room, and to visual assessment by a nurse all decreased. The largest decrease was in median time to provider, from 43 minutes in the current state to 7 minutes during pilot 2.

Conclusions: Rapid process improvement methodology was used to design and test a front-end model that reduced patient waiting time. Our experience demonstrates the feasibility of employing Lean principles and the Model for Improvement in actual practice environments to rapidly improve care delivery processes in pediatric emergency departments.
