Lean Participative Process Improvement: Outcomes and Obstacles in Trauma Orthopaedics

Area of Science:

• Healthcare Management
• Surgical Safety
• Quality Improvement

Background:

• Lean methodology is a systems approach to improve efficiency and quality.
• Its application in surgical care requires investigation for potential synergistic effects with other improvement strategies.

Purpose of the Study:

• To evaluate the effectiveness of a Lean methodology-based "systems" approach in enhancing surgical care.
• To explore synergy between different improvement methodologies in a healthcare context.

Main Methods:

• A controlled before-after study was conducted in UK hospital theatres (orthopaedic trauma vs. elective).
• Intervention involved a Lean training course and a 6-month staff-led improvement project.
• Outcomes measured included WHO checklist compliance, "glitch count," Oxford NOTECHS II, length of stay, complications, and readmissions.

Main Results:

• No significant improvements were observed in team performance or patient outcome measures.
• The intervention theatre improved first patient arrival time by 20 minutes.
• 576 cases were studied pre-intervention and 465 post-intervention.

Conclusions:

• The implemented Lean system improvement did not enhance measured safety processes or patient outcomes.
• A key finding was the tension between staff ownership and project direction in Lean initiatives.
• Adequate time and space for staff engagement are critical for successful Lean projects in healthcare.
