MIMIC-IV

Retrospectively collected medical data has the opportunity to improve patientcare through knowledge discovery and algorithm development. Broad reuse ofmedical data is desirable for the greatest public good, but data sharing mustbe done in a manner which protects patient privacy. Here we present MedicalInformation Mart for Intensive Care (MIMIC)-IV, a large deidentified datasetof patients admitted to the emergency department or an intensive care unit atthe Beth Israel Deaconess Medical Center in Boston, MA. MIMIC-IV contains datafor over 65,000 patients admitted to an ICU and over 200,000 patients admittedto the emergency department. MIMIC-IV incorporates contemporary data andadopts a modular approach to data organization, highlighting data provenanceand facilitating both individual and combined use of disparate data sources.MIMIC-IV is intended to carry on the success of MIMIC-III and support a broadset of applications within healthcare.
