Dimension table describing itemid. Defines concepts recorded in the events table in the ICU module.
The ICU module contains data sourced from the clinical information system at the BIDMC: MetaVision (iMDSoft). MetaVision tables were denormalized to create a star schema where the icustays and d_items tables link to a set of data tables all suffixed with “events”. Data documented in the icu module includes intravenous and fluid inputs (inputevents), patient outputs (outputevents), procedures (procedureevents), information documented as a date or time (datetimeevents), and other charted information (chartevents). All events tables contain a stay_id column allowing identification of the associated ICU patient in icustays, and an itemid column allowing identification of the concept documented in d_items.
Charted items occurring during the ICU stay. Contains the majority of information documented in the ICU.
Documented information which is in a date format (e.g. date of last dialysis).
Tracking information for ICU stays including adminission and discharge times.
Information documented regarding continuous infusions or intermittent administrations.
Information regarding patient outputs including urine, drainage, and so on.
Procedures documented during the ICU stay (e.g. ventilation), though not necessarily conducted within the ICU (e.g. x-ray imaging).
