On the surface, it may appear that a cancelled shifts is a simple concept. Someone is unable to work, so their shift ends up being cancelled. When one considers this a little further, it becomes clear that this is more complex. With respect to required shift tallies, are there circumstances where a shift may count towards required shift tallies? How are cancelled shifts tracked, and who is responsible for that? Does a scheduling system allow for tracking not only the cancelled shift but also all of the associated details, or is this tracked outside the scheduling system due to a featureless scheduling platform? What type of cancelled shift reports are available? For several years, OnServiceMD has developed and enhanced how a program can track and view cancelled shifts, add key corresponding data elements and provide cancelled shift reports with key data fields. Additional features released in 2024 provide a program with even more customization regarding how they track and handle cancelled shifts. This is another example of how OnServiceMD has refined and optimized the features needed in a complete, robust scheduling system for doctors and APPs.
