decision_9 {drugprepr}

Decision 9: handle overlapping prescription periods

Description

In situations where one prescription starts before another (for the same patient and drug) finishes, this function will either implicitly sum the doses (i.e. do nothing) or it will divide the intervals into non-overlapping subsets, shifting these sub-intervals forward in time until there is no overlap.

Usage

decision_9(data, decision = "a")

Arguments

data

a data frame

decision

one of the following strings:

"a"

allow overlapping prescriptions (implicitly sum doses)

"b"

move later prescription to next available time that this product is not prescribed

Details

The underlying algorithm for shifting overlapping intervals is implemented by the internal function shift_interval.
