Integrating Lean Exploration Loops Into Healthcare Facility Design

Purpose: To explore how Lean can add value during the schematic phase of design through providing additional resources and support to project leadership and the architectural design team. Background: This case study–based research took place at one large academic hospital during design efforts of surgical tower to house 19 operating rooms (ORs) and support spaces including pre- and post-op, central processing and distribution, and materials management. Surgical services project leadership asked for Lean practitioners’ support during the design process. Methods: Lean Exploration Loops (LELs) were conducted to generate evidence to support stakeholders, as they made important decisions about the new building design. The analyses conducted during LELs during the schematic phase were primarily conducted using express workouts (EWOs) and were focused on the flow of patients, staff, and family throughout the pavilion. Results: LELs resulted in recommendations for key design features (e.g., number of pre- and post-op bays per OR floor, location of doors, scrub sinks, stretcher alcoves, equipment storage, and sterile core areas). Two-sided pre- and post-op bays with an inner clinical workspace and an outer patient transport corridor were recommended. Communicating elevator and a centrally located stairwell for staff to alleviate stress on the main bank of elevators at peak usage times were also suggested. Conclusions: We found Lean tools and methods to be of most value during schematic phase when focused on detailed process and layout analysis, while acknowledging the usefulness of focused EWOs to generate the evidence needed for the decision-making.
