A unique way to improve OR turnover time

Dr. Herrera gets his head shavedTwo staff leaders challenged the hospital’s OR team to keep patients on schedule for surgeries by reducing turnover time between cases to less than 20 minutes, while maintaining USAP’s standards of excellence for cleanliness, preparation and patient care.

The staff accepted the challenge and won. Dr. Hector Herrera and Mr. Alfonso Chicas succeeded in motivating the team to new heights, yet lost from a follicle perspective. They had to shave their heads per the bet with the OR team.
