Compute in-hospital mortality using CIHI DAD

in_hospital_mortality.Rd

in_hospital_mortality returns whether a patient has deceased in hospital based on the CIHI DAD field discharge disposition

Usage

in_hospital_mortality(ipadmdad, suicide = FALSE)

Arguments

ipadmdad

(data.frame or data.table)
Table with all relevant encounters of interest from DRM table "ipadmdad" (see GEMINI Data Repository Dictionary). Must contain two fields: genc_id and discharge_disposition.

suicide

(logical)
a TRUE/FALSE argument indicating whether suicides in facility should be counted towards in-hospital mortality rate or not.

Value

data.table with the same number of rows as input ipadmdad, with additional derived boolean field labelled as in_hospital_mortality_derived. Possible values are TRUE, FALSE or NA, where NA indicates missing discharge disposition.

Details

This function takes the CIHI DAD "discharge disposition" field (Group 05, Field 05 As of 19/20 CIHI DAD) and generates a boolean variable indicating whether the patient has deceased during hospital stay.

The current version of the function captures the four possible values indicating that a patient has deceased in hospital:

  • 7: Died (Deprecated post 2017)

  • 72: Died in Facility

  • 73: Medical Assistance in Dying

  • 74: Suicide in Facility (Excluded in calculation by default; can be included by setting suicide argument to TRUE)

Warning

NA values in returned data.table indicate missing discharge disposition field values.
