unit modified byunt_mod_by

Captures the user identifier of the individual who last updated a clinical care unit record. Supports audit trail requirements, data governance, and accountability tracking within EHR and clinical data warehouse systems to ensure record integrity and compliance.

unit modified dateunt_mod_dt

The timestamp recording the most recent update to a clinical care unit record in EHR and hospital administration systems. Data engineers rely on this field for incremental load strategies, change data capture pipelines, and audit trail validation during data warehouse refresh cycles.

unit modified timeunt_mod_tm

Records the exact timestamp when a clinical care unit record was last updated. Critical for audit trail maintenance, data synchronization across systems, version control, and regulatory compliance tracking within EHR and clinical data warehouse environments.

unit nameunt_nm

The display label text identifying a specific clinical care unit, such as Cardiology ICU or Pediatric Ward, in EHR and hospital administration systems. Data engineers use this field for dimension table lookups, facility reporting joins, and standardizing unit identifiers across source system integrations.

unit noteunt_nt

The free-text annotation associated with a clinical care unit record in EHR and hospital administration systems, capturing operational details or special instructions. Data engineers must handle this unstructured field carefully during ETL, applying NLP parsing or exclusion rules to prevent pipeline failures.

unit numberunt_nbr

The unique numeric reference identifier assigned to a clinical care unit in EHR and hospital administration systems. Data engineers use this field as a primary or foreign key when joining unit dimension tables to patient census, staffing, or claims data across integrated healthcare data warehouses.

unit onset dateunt_onset_dt

Captures the date on which a condition, symptom, or clinical event began for a patient within a clinical care unit. Used in diagnosis coding, disease progression tracking, clinical documentation, and outcomes analysis within EHR and care management systems.

unit oxygen saturationunt_o2sat

Records the peripheral oxygen saturation (SpO2) percentage measured for a patient within a clinical care unit. A critical vital sign used to monitor respiratory status, guide oxygen therapy decisions, and trigger clinical interventions in acute and critical care settings.

unit paid amountunt_pd_amt

The dollar amount paid for services rendered within a clinical care unit, reflecting reimbursement from insurers, patients, or other payers. Used in revenue cycle management, claims reconciliation, and financial reporting across healthcare billing and administrative systems.

unit paid dateunt_pd_dt

Records the date on which payment was received or processed for services associated with a clinical care unit. Used in revenue cycle management, accounts receivable tracking, and financial reporting within healthcare billing and claims processing systems.

unit parentunt_prnt

The identifier linking a clinical care unit to its superior organizational entity in EHR and hospital administration hierarchies, such as a department or facility. Data engineers use this field to construct recursive hierarchy models, rollup aggregations, and multi-level reporting structures in analytics platforms.

unit percentageunt_pct

The calculated ratio value representing a proportion metric for a clinical care unit in EHR, quality, and reporting systems, such as occupancy rate or staffing ratio. Data engineers use this field for KPI dashboards, benchmark comparisons, and validating derived metrics against source system calculations.

unit periodunt_prd

The defined time span or duration associated with a clinical care unit's operational or reporting cycle in EHR and hospital administration systems. Data engineers use this field to align unit-level data with fiscal periods, shift schedules, or longitudinal patient stay windows during time-series analysis.

unit phoneunt_ph

The direct telephone contact number assigned to a clinical care unit in EHR and hospital administration systems. Data engineers use this field to support provider directory integrations, facility master data management, and contact information validation during member or patient demographic reconciliation workflows.

unit planunt_pln

Documents the clinical treatment or care plan established for a patient within a specific care unit, outlining intended interventions, goals, and follow-up actions. Used in care coordination, clinical documentation, and quality reporting within EHR systems.

unit policy numberunt_pol_nbr

Stores the insurance policy number associated with a patient receiving care in a clinical unit. Used to verify coverage eligibility, process claims, and coordinate benefits across payer systems, supporting accurate billing and revenue cycle management workflows.

unit preferred nameunt_pref_nm

Records the name by which a patient or individual prefers to be addressed within a clinical care unit setting. Supports patient-centered care, accurate identity verification, and respectful communication in clinical documentation and care delivery workflows.

unit priceunt_prc

Represents the defined cost per unit of a service, supply, medication, or procedure charged within a clinical care unit. Used in charge capture, claims pricing, cost accounting, and financial analysis across healthcare revenue cycle and supply chain systems.

unit primary indicatorunt_prim_ind

A flag designating whether a clinical care unit record represents the primary association, such as primary diagnosis, primary payer, or primary unit assignment. Used to prioritize records in billing, reporting, and clinical workflows where a single primary value is required.

unit priorityunt_prty

The importance or urgency ranking assigned to a clinical care unit in EHR, scheduling, and hospital administration systems, used to govern patient triage, resource allocation, and workflow sequencing. Data engineers use this field to implement priority-based routing logic and sort order in downstream reporting pipelines.
