Require cohort subjects to have (or not have) events of a concept list
Source:R/requireConceptIntersect.R
requireConceptIntersect.Rd
requireConceptIntersect()
filters a cohort table based on a requirement
that an individual is seen (or not seen) to have events related to a concept
list in some time window around an index date.
Usage
requireConceptIntersect(
cohort,
conceptSet,
window,
intersections = c(1, Inf),
cohortId = NULL,
indexDate = "cohort_start_date",
targetStartDate = "event_start_date",
targetEndDate = "event_end_date",
inObservation = TRUE,
censorDate = NULL,
atFirst = FALSE,
name = tableName(cohort),
.softValidation = TRUE
)
Arguments
- cohort
A cohort table in a cdm reference.
- conceptSet
A conceptSet, which can either be a codelist or a conceptSetExpression.
- window
A list of vectors specifying minimum and maximum days from
indexDate
to consider events over.- intersections
A range indicating number of intersections for criteria to be fulfilled. If a single number is passed, the number of intersections must match this.
- cohortId
Vector identifying which cohorts to modify (cohort_definition_id or cohort_name). If NULL, all cohorts will be used; otherwise, only the specified cohorts will be modified, and the rest will remain unchanged.
- indexDate
Name of the column in the cohort that contains the date to compute the intersection.
- targetStartDate
Start date of reference in cohort table.
- targetEndDate
End date of reference in cohort table. If NULL, incidence of target event in the window will be considered as intersection, otherwise prevalence of that event will be used as intersection (overlap between cohort and event).
- inObservation
If TRUE only records inside an observation period will be considered.
- censorDate
Whether to censor overlap events at a specific date or a column date of the cohort.
- atFirst
If FALSE the requirement will be applied to all records, if TRUE, it will only be required for the first entry of each subject.
- name
Name of the new cohort table created in the cdm object.
- .softValidation
Whether to perform a soft validation of consistency. If set to FALSE four additional checks will be performed: 1) a check that cohort end date is not before cohort start date, 2) a check that there are no missing values in required columns, 3) a check that cohort duration is all within observation period, and 4) that there are no overlapping cohort entries

library(CohortConstructor)
cdm <- mockCohortConstructor(conditionOccurrence = TRUE)
cdm$cohort2 <- requireConceptIntersect(
cohort = cdm$cohort1,
conceptSet = list(a = 194152),
window = c(-Inf, 0),
name = "cohort2")
