Cases are colour coded according to their priority level and each case is placed onto the wait list by the computer according to it’s individual timeline.

Dynamic Multi priority scheduling

When a surgeon books a case on the On-Time system he/she enters a wait time target. This starts a timeline for the case on the On-Time computer and this timeline is inter collated with all of the other timelines that are already on the list.

By comparing these timelines the On-Time computer is able to build a representation of the emergency wait list using a simple algorithm. This wait list acts as a decision support tool for the operating room management by helping them to decide which case should go to the operating room next.

If a case goes beyond its wait time target the On-Time system continues to measure this as “overdue case” time. Overdue case time is recorded in red and is weighted at a different rate depending on the urgency level of the case involved. A class one emergency will accrue overdue case time at a rate that is two times greater than a class two case. Overdue case time is a unique metric that is used to optimize the allocation of surgical resources.
