In CohortUtilisation: Healthcare Resource Utilization on OMOP CDM Cohorts

Generate Hospitalization and Readmission Cohorts (Stage 1 & 2)

Description

Extracts inpatient visits from visit_occurrence, collapses contiguous or overlapping stays into discrete hospitalization episodes, and derives readmission cohorts within a specified washout window.

Usage

compute_hospitalization_cohorts(
  cdm,
  name,
  visit_concept_ids = c(9201L, 262L, 32037L, 581379L),
  readmission_window = 30L
)

computeHospitalizationCohorts(
  cdm,
  name,
  visitConceptIds = c(9201L, 262L, 581379L),
  icuConceptIds = 32037L,
  readmissionWindow = 30L,
  readmission_window = NULL
)

Arguments

cdm	A cdm_reference object.
name	String specifying the cohort table name in the write schema.
visit_concept_ids	Integer vector of OMOP visit concept IDs. Default: c(9201L, 262L, 32037L, 581379L).
readmission_window	Backward compatible snake_case parameter.
visitConceptIds	Integer vector of OMOP visit concept IDs. Default: c(9201L, 262L, 581379L).
icuConceptIds	Integer vector of OMOP ICU visit concept IDs. Default: 32037L.
readmissionWindow	Maximum days between previous discharge and next admission. Default: 30.

Value

An omopgenerics cohort table with cohort definitions:

• 1: hospitalization (collapsed inpatient episodes)

• 2: readmission (episodes occurring within readmission_window days of prior discharge)
