unit pulseunt_pulse

Records the heart rate in beats per minute (BPM) measured for a patient within a clinical care unit. A fundamental vital sign used to assess cardiovascular status, monitor patient condition, and support clinical decision-making in acute and routine care settings.

unit quantityunt_qty

The count or volume measurement associated with a clinical care unit in EHR, claims, and pharmacy systems, representing resources, patients, or supplies. Data engineers use this field to validate capacity metrics, reconcile inventory records, and support utilization reporting across inpatient and outpatient data models.

unit raceunt_race

Captures the self-reported racial identity of a patient associated with a clinical care unit record. Used in demographic reporting, health equity analysis, social determinants of health assessments, and regulatory compliance reporting across healthcare information systems.

unit rangeunt_rng

The minimum and maximum value boundaries defined for a clinical care unit metric in EHR and quality management systems, such as acceptable lab result thresholds or staffing levels. Data engineers use this field to implement data validation rules, outlier detection, and reference range lookups in clinical data pipelines.

unit rateunt_rt

The per-unit price or reimbursement value associated with a clinical care unit or service in claims, EHR, and contract management systems. Data engineers use this field to calculate expected payments, validate fee schedule applications, and reconcile billed versus allowed amounts in financial analytics pipelines.

unit ratingunt_rtg

A scored assessment value assigned to a specific inpatient or clinical care unit, reflecting performance metrics, quality indicators, or acuity levels. Used in hospital administration and quality reporting to evaluate and compare unit-level outcomes and operational efficiency.

unit ratiount_ratio

A proportional measure calculated at the inpatient care unit level, such as nurse-to-patient staffing ratios or bed occupancy ratios. Used in hospital operations and workforce planning to assess resource allocation and care delivery capacity within a unit.

unit reasonunt_rsn

The explanatory text or code describing why a specific action, change, or status was applied to a clinical care unit record in EHR and hospital administration systems. Data engineers use this field to support audit logging, change history tracking, and root cause analysis in data quality and compliance workflows.

unit received dateunt_rcvd_dt

The date on which a specific item, specimen, supply, or referral was received by a clinical care unit. Used in hospital operations, laboratory tracking, and supply chain management to establish receipt timelines and support audit and compliance workflows.

unit referenceunt_ref

The external identifier or pointer linking a clinical care unit record to a related entity in EHR, claims, or interoperability systems, such as a HL7 location code or facility NPI. Data engineers use this field to establish cross-system joins, master data linkages, and reference data reconciliation in integration pipelines.

unit resolution dateunt_resol_dt

The date on which an issue, incident, order, or clinical condition associated with a care unit was formally resolved or closed. Used in clinical documentation and quality management to track resolution timelines and measure response effectiveness at the unit level.

unit respirationunt_resp

The respiratory rate measurement, expressed in breaths per minute, recorded for a patient within a specific inpatient care unit. Used in clinical vital signs documentation to monitor patient breathing status and detect deterioration requiring intervention at the unit level.

unit resultunt_rslt

The outcome measurement or value recorded for a clinical care unit process or test in EHR, quality, and lab systems, such as infection rates or patient satisfaction scores. Data engineers use this field to populate quality metric tables, support HEDIS measure calculations, and feed performance dashboards in analytics platforms.

unit review systemsunt_ros

Identifies the body systems assessed during clinical review within a specific inpatient or ambulatory care unit, such as ICU or med-surg. Used in clinical documentation to capture systematic physical examination findings and support continuity of care across nursing and physician workflows.

unit revisionunt_rev

A numeric or alphanumeric identifier indicating the version or update iteration of a record, protocol, order, or document associated with a clinical care unit. Used in document control and clinical data management to track changes and maintain accurate version histories.

unit riskunt_rsk

A risk level classification or score assigned to a patient or process within a clinical care unit, such as fall risk, pressure injury risk, or infection risk. Used in inpatient care planning and safety protocols to guide preventive interventions and resource prioritization.

unit routeunt_rte

The administration pathway specified for a medication or treatment delivered within a clinical care unit, such as oral, intravenous, or intramuscular. Used in pharmacy and nursing workflows to ensure correct medication delivery and support medication administration record documentation.

unit scheduled dateunt_sched_dt

The planned calendar date on which a procedure, transfer, service, or clinical activity is scheduled to occur within or for a specific care unit. Used in hospital scheduling and capacity planning systems to coordinate care delivery and manage unit-level workflows.

unit scheduled timeunt_sched_tm

The planned clock time at which a procedure, transfer, or clinical activity is scheduled to occur within a specific care unit. Used alongside the scheduled date in hospital operations and clinical scheduling systems to coordinate staffing, equipment, and patient flow.

unit scoreunt_scr

The calculated numeric rating assigned to a clinical care unit based on performance, risk, or quality criteria in EHR and quality management systems. Data engineers use this field to populate scorecards, support value-based care program reporting, and drive ranking logic in provider and facility analytics models.
