Population

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.

The preferred spoken or written language of the patient receiving the vaccine, recorded at the time of immunization. Used in immunization systems to ensure vaccine information statements, consent forms, and post-vaccination instructions are provided in the patient's primary language to support informed consent compliance.

The patient's family surname recorded at the time of vaccine administration. Used in immunization registries and EHR systems for patient identity matching, record lookup, and demographic verification to ensure accurate attribution of vaccination events to the correct patient record.

The patient's full official name as documented on government-issued identification at the time of vaccine administration. Used in immunization registries for identity verification, regulatory reporting, and ensuring vaccination records are correctly attributed to the legally recognized patient identity.

A hierarchical classification value assigned to a vaccination record in EHR and public health registry systems. Denotes the tier of a vaccine series (e.g., primary, booster, catch-up) to support dose-counting logic, CVX code mapping, and immunization schedule compliance tracking.

The state or national professional license identifier of the clinician or healthcare provider who administered the vaccine. Captured in immunization records to document accountability, meet regulatory requirements, and support audit trails verifying that vaccinations were performed by appropriately credentialed personnel.

The patient's legal marital status recorded at the time of vaccine administration. Captured as part of the demographic profile in immunization registries and EHR systems to support complete patient records, population health reporting, and eligibility determinations for certain public health vaccination programs.

The enterprise master patient index identifier linked to a vaccination administration record, enabling consistent patient identification across disparate healthcare systems. Used to reconcile immunization records from multiple facilities, registries, or health information exchanges into a unified longitudinal patient immunization history.

The upper threshold value defined for a specific vaccine-related measurement or dosing parameter, such as maximum allowable dose quantity or maximum patient age for eligibility. Used in immunization clinical decision support rules to enforce safety limits and ensure compliance with vaccine administration guidelines.

The facility-assigned medical record number of the patient who received the vaccine, linking the immunization event to their complete medical record. Used in EHR and immunization registry systems to retrieve patient history, reconcile vaccination records, and support continuity of care across clinical encounters.

The patient's middle name or initial recorded at the time of vaccine administration. Used in immunization registries and EHR systems as a supplementary demographic identifier to disambiguate patients with similar first and last names and improve accuracy of patient record matching across healthcare systems.
