Myocardial Infarction 1-5Y phenotyping

description: >-
  This file defines a prediction task that predicts, for patients who will both (a) not have a MI within 1
  year of their hospital admission and (b) have some data available at least 5 years after their admission,
  whether they will have a MI between 1 and 5 years after their hospital admission. Note that these criteria
  induce censoring impacts on the included distribution which must be accounted for before this task could be
  deployed.

  MI: 
    code: { regex: "^DRG.*MYOCARDIAL INFARCTION.*" }
  hospital_admission:
