MIMIC4更新至2.2版本
https://www.physionet.org/content/mimiciv/2.2/

MIMIC-IV v2.2 was released in January 2023. It added provider identifiers, imputed hadm_id for a number of rows in emar, and changed the subset of subject_id which are held out. Final row counts are available in the validation scripts published with the MIMIC Code Repository [6]. For clarity, after removal of the test set, the row counts are as follows:

  • patients: 299,712 (was 315,460 in v2.0)
  • admissions: 431,231 (was 454,324 in v2.0)
  • icustays: 73,181 (was 76,943 in v2.0)

icu module

  • caregiver
    • New table in v2.2. Contains one column: caregiver_id, a deidentified integer which uniquely represents a single caregiver or provider. These identifiers are sourced from the MetaVision ICU system. When present in a table, it indicates the user who documented the data into MetaVision. For example, the caregiver_id associated with a row indicating mechanical ventilation in the procedureevents table represents the user who documented the event, and not the provider who performed the procedure.

    • Added the caregiver_id column. This column is a deidentified integer representing the care provider who documented the data for the given row.

hosp module

  • provider
    • New table in v2.2. Contains one column: provider_id, a deidentified string which uniquely represents a single caregiver or provider. These identifiers are sourced from the hospital wide EHR system, and used in a variety of contexts across tables in the module.
  • admissions
    • New column: admit_provider_id, a deidentified string representing the provider who admitted the patient.
  • emar
    • New column: enter_provider_id, a deidentified string representing the provider who entered the medication administration information into the database.
    • Fixed a bug where a subset of emar rows (713,117, ~2.5%) did not have an hadm_id even though they were associated with a given hospitalization. These rows occur outside of the administratively documented admission and discharge times for a hospitalization, but are still considered as administered during that hospitalization in the raw data.
  • labeventsmicrobiologyeventspoeprescriptions
    • New column: order_provider_id, a deidentified string representing the provider who ordered the corresponding event (e.g. the lab test in the case of labevents, or the medication in the case of prescriptions).
