Population

The identifier of the user who manually entered or transcribed the immunization record into the health information system, which may differ from the administering clinician. Important for distinguishing historical vaccine records entered retrospectively from those documented at the point of care.

The patient ethnicity captured at the time of immunization, used to support population health monitoring, health equity analysis, and public health surveillance. Enables identification of vaccination disparities across demographic groups and informs targeted outreach strategies for underserved communities.

The validity end date assigned to a vaccination record in EHR and immunization registry systems (e.g., IIS, Epic, Cerner). Tracks vaccine lot expiration or administration validity windows, ensuring compliance with CDC VIS and HL7 immunization messaging standards.

A unique identifier assigned to an immunization record by an external system, such as a state immunization information system, pharmacy system, or third-party registry. Used to link and reconcile vaccination records across disparate platforms and ensure accurate immunization history consolidation.

The fax number associated with the facility, provider, or patient contact recorded in the immunization workflow. Used to transmit vaccination records, consent forms, or immunization documentation to external providers, school health programs, or public health departments requiring physical record submission.

The charge associated with administering a vaccine, encompassing the vaccine product cost and administration fee. Captured in billing and claims workflows to support reimbursement from insurance payers, Vaccines for Children program reconciliation, and patient invoicing for non-covered immunization services.

The first name of the patient who received the vaccine, as recorded in the immunization encounter. Used to verify patient identity during vaccine administration, match records submitted to immunization registries, and ensure accurate attribution of vaccination history within the health record.

A binary status marker (0/1 or Y/N) on a vaccination record in EHR, claims, and public health registry systems. Indicates conditions such as contraindication, refusal, or completion status, supporting HEDIS immunization measure reporting and care gap identification workflows.

The recommended or prescribed dosing interval for a vaccine series, specifying how often doses should be administered, such as annually for influenza or on a multi-dose schedule for HPV. Drives clinical reminders, schedule adherence tracking, and immunization series completion reporting.

The complete legal name of the patient receiving the vaccine, combining first, middle, and last name as documented in the immunization record. Used for patient identity verification, immunization registry submissions, school and occupational health compliance reporting, and cross-system record matching.

The biological sex or gender identity of the patient recorded at the time of vaccine administration. Used in immunization registries and EHR systems to support demographic tracking, dose eligibility rules, and public health reporting for gender-specific vaccine recommendations.

The blood glucose level measured at the time of vaccine administration, captured when clinically relevant. Used in immunization records to document pre-vaccination metabolic status, particularly for diabetic patients where glucose levels may influence administration decisions or adverse event monitoring.

The insurance group policy identifier associated with the patient's coverage at the time of vaccine administration. Used in immunization billing workflows to link vaccination events to the correct health plan group for claims submission, coverage verification, and reimbursement processing.

The hemoglobin concentration measured at or near the time of vaccine administration, documenting the patient's blood oxygen-carrying capacity. Captured in immunization records to assess patient health status prior to vaccination and support clinical decision-making for patients with anemia or hematologic conditions.

The narrative description of the patient's current clinical condition or symptoms documented at the time of vaccine administration. Captured in immunization records to provide clinical context, document contraindications, and support decision-making regarding whether to proceed with or defer vaccination.

A unique system-generated or source-assigned key (e.g., UUID, OID) for a vaccination record in EHR, IIS, and claims systems. Used for deduplication, cross-system reconciliation, and HL7 FHIR Immunization resource linkage across provider and payer data pipelines.

An ordinal position number assigned to a vaccination record within a series or dataset in EHR and immunization registry systems. Used to sequence multi-dose vaccine series (e.g., HPV, Hepatitis B) and support dose-validity logic in HEDIS and clinical decision support rules.

A boolean or coded state value on a vaccination record in EHR, claims, and member health management systems. Signals whether a patient has received, refused, or is due for a specific vaccine, supporting quality measure calculations such as HEDIS Childhood Immunization Status (CIS).

Structured or free-text guidance associated with a vaccination record in EHR and pharmacy dispensing systems. Captures administration directives, patient counseling notes, or special handling requirements (e.g., cold chain), and maps to HL7 FHIR Immunization.note or SIG fields.

The unique surrogate or natural key value assigned to a specific vaccination administration record within the immunization data system. Used as the primary reference identifier to link, retrieve, and join immunization records across clinical databases, registries, and downstream reporting systems.
