Implementing lean management in an academic otolaryngology operating room significantly reduced operating room turnover and turnaround times. This efficiency improvement also boosted staff morale without negatively impacting surgical resident education or financial performance.

Area of Science:

  • Healthcare Management
  • Surgical Operations
  • Process Improvement

Background:

  • Lean management principles aim to enhance productivity by minimizing waste.
  • Surgical settings present numerous opportunities for efficiency improvements.
  • This study investigated the impact of lean thinking in an academic otolaryngology operating room.

Purpose of the Study:

  • To assess if systematic lean thinking implementation improves operating room efficiency.
  • To evaluate the effect on profitability, team morale, and resident education.
  • To determine the financial implications and scalability of lean practices in surgery.

Main Methods:

  • A prospective quasi-experimental study over 18 months in an academic otolaryngology OR.
  • Measured operating room turnover and turnaround times during baseline and intervention periods.

  • Assessed teamwork, morale, and resident education via surveys; applied a profit model for financial analysis.

    • Main Results:

    • Turnover time decreased from 38 to 29 minutes (p < 0.001) and turnaround time from 89 to 69 minutes (p < 0.001).
    • Composite morale scores significantly improved post-implementation (p = 0.011).
    • Educational metrics remained unchanged; projected annual capacity increase of 6,500 hours across the surgical suite.

    Conclusions:

    • Lean management techniques successfully enhanced operating room efficiency and staff morale in an academic surgical service.
    • The implementation sustained surgical resident education and demonstrated significant financial benefits.
    • Scaling lean thinking across an entire academic surgical suite offers considerable financial gains.
