Redesigning operating room (OR) processes significantly reduced nonoperative time (NOT), including room turnover and anesthesia activities. This multidisciplinary approach offers substantial OR efficiency gains, particularly for shorter procedures.

Area of Science:

  • Healthcare Operations
  • Surgical Process Improvement
  • Anesthesiology

Background:

  • Operating rooms (ORs) are vital for patient care and hospital revenue.
  • Significant OR time is lost to nonoperative activities.
  • Nonoperative time (NOT) includes room turnover and anesthesia induction/emergence.

Purpose of the Study:

  • To test the hypothesis that redesigning interoperative processes reduces NOT.
  • To decrease nonoperative time (NOT) in operating rooms.

Main Methods:

  • A prospective study was conducted in 2 ORs at an academic medical center.
  • A multidisciplinary team planned and implemented process changes over 3 months.
  • Focus on minimizing OR tasks, parallel activities, and reducing disruptions for cases ≤ 2 hours.

Main Results:

  • NOT significantly decreased (42.2 vs. 65 minutes, P < .001).
  • Turnover time (26.4 vs. 42.8 minutes) and anesthesia time (16.9 vs. 21.9 minutes) also reduced significantly (P < .001).
  • Process delays occurred in 70% of cases exceeding the 35-minute NOT target.

Conclusions:

  • Coordinated, multidisciplinary process redesign effectively reduces NOT.
  • The optimized process benefits ORs, especially for procedures ≤ 2 hours.
  • Further improvements are possible, indicated by residual process-related delays.
