What is the key difference between the actions of "Let Expire" and "Discontinue" for an order?

The key distinction regarding the "Let Expire" action lies in its operational mechanics concerning the timing of an order's validity. When an order is marked to "Let Expire," it remains active and functional until it reaches its designated end time. This means that the order will continue to be acknowledged within the system, but once the predetermined expiration time is reached, it will no longer be enforceable or recognized as active.

This functionality is particularly useful in healthcare settings where certain orders might need to operate for a specified duration and then be automatically disregarded without requiring manual intervention at the end of that period.

In contrast, the other options involve different actions that do not encapsulate this specific time-related aspect of order management. For instance, marking an order as "Discontinue" does not focus on the time aspect but rather clears it from being active, thereby effectively ending its execution, regardless of whether a specified end time exists.
