Medications like pain management would have an optional, not mandatory, setting for a frequency range (ie q 6-8hrs).
When utilized, the medication would have an open highlighted box (border color/no fill) around the hours in which the medication could be given. No 'missed treatment' alert would occur until the final hour of the range if medication had not already been given. SmartFlow would then maintain a running frequency where in the next occurance would only poplate/highlight once the current occurance was initialed (thus maintaining a true q6-8 range).
This would be particularly helpful for those medications that walk the fine line between necessary and PRN such as pain medication.
