Source: R/Task_Readmission30DaysMIMIC4.R
Readmission30DaysMIMIC4.Rd

This task processes patient data from MIMIC-IV to predict whether a patient will be readmitted within 30 days after discharge. It uses sequences of conditions, procedures, and drugs as input features.

Format

R6Class object.

Public Fields

task_name

Character. The name of the task ("Readmission30DaysMIMIC4").

input_schema

List. Input schema, including:

  • conditions: Sequence of condition codes.

  • procedures: Sequence of procedure codes.

  • drugs: Sequence of drug codes.

output_schema

List. Output schema:

  • readmission: Binary indicator of readmission within 30 days.

Public Methods

initialize()

Initializes the task by setting the task name, input and output schema.

call(patient)

Generate samples from a patient object.

patient

An object that implements get_events() for MIMIC-IV.

Returns

A list of named lists with features and 30-day readmission label.

Super class

RHealth::BaseTask -> Readmission30DaysMIMIC4

Methods

Public methods

Inherited methods

Method new()

Initialize the Readmission30DaysMIMIC4 task. Sets the task name and defines the expected input/output schema.

Usage

Readmission30DaysMIMIC4$new()

Method call()

Generate samples by processing a patient object. Excludes patients under 18 years old and visits without complete data. For each valid admission, extracts condition, procedure, and drug codes as feature sequences and computes a binary readmission label within 30 days.

Usage

Readmission30DaysMIMIC4$call(patient)

Arguments

patient

An object with a get_events method for extracting MIMIC-IV events.

Returns

A list of named lists, each representing one admission sample.

Method clone()

The objects of this class are cloneable with this method.

Usage

Readmission30DaysMIMIC4$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.

Examples

if (FALSE) { # \dontrun{
task <- Readmission30DaysMIMIC4$new()
samples <- task$call(patient)
} # }
