Operating Room Utilization
OR utilization is a measure of the use of an operating room that is properly staffed with people needed to successfully deliver a surgical procedure to a patient.
Raw utilization is the total hours of elective cases performed within OR time divided by the hours of allocated block time.
Raw Utilization = total hours of cases performed ÷ total hours of OR time allocated
Adjusted utilization uses the total hours of elective cases performed within OR block time, including "credit" for the turnover times necessary to set up and clean up ORs.
Adjusted Utilization = ÷ total hours of OR time allocated
Factors affecting utilization rates include: the accuracy of estimated case times, cancellation rate, number of add-ons available to fill gaps, longest cases go first, the time of day as utilization typically is highest in the morning and lowest in the evening, outpatient centers have lower utilization, and other constraints (i.e., surgeon can only use room 12, or start at 11 am).
Improvements in operating room efficiency can have a major impact on hospital staff and finances as well as operating room management.

Famous quotes containing the words operating room, operating and/or room:
“Many people operate under the assumption that since parenting is a natural adult function, we should instinctively know how to do it—and do it well. The truth is, effective parenting requires study and practice like any other skilled profession. Who would even consider turning an untrained surgeon loose in an operating room? Yet we “operate” on our children every day.”
—Louise Hart (20th century)
“... the modern drama, operating through the double channel of dramatist and interpreter, affecting as it does both mind and heart, is the strongest force in developing social discontent, swelling the powerful tide of unrest that sweeps onward and over the dam of ignorance, prejudice, and superstition.”
—Emma Goldman (1869–1940)
“The cruellest lies are often told in silence. A man may have sat in a room for hours and not opened his mouth, and yet come out of that room a disloyal friend or a vile calumniator.”
—Robert Louis Stevenson (1850–1894)
