Details

Computes time time off since the last event of the specified intervention, in the first 28 days, per encounter. Missing values are imputed with NAs, as encounters with no events of the specified interventions are assumed to not have had that intervention. The function currently works only for interventions that have both a start time and end time.

Value

data_frame:

• chr: patient_id_encounter

• num: time off intervention_name
