Improving OR First Case Start Times

Effective use of OR time is imperative to achieve profitable margins. A key measure of OR efficiency is starting the first case of the day on-time. The University of Kansas Health System used lean methodology and analytics to redesign work flow, identifying opportunities with OR scheduling to improve on-time performance. Staggered start times with ongoing monitoring and visibility of performance have led to substantial improvement in first case on-time starts.


  • 28% relative improvement first case on-time starts.
  • Four staggered start times, supporting on-time performance.
  • Improved surgeon and staff satisfaction.
