EHR Data Parsing

Overview

This skill encodes Python pipelines for parsing clinical data from two dominant formats: HL7v2 (pipe-delimited messages) and FHIR R4 (JSON resources). It covers extraction of patient demographics, lab results, diagnoses, and medications, plus format conversion and data quality checks.

Scope:

• HL7v2 message parsing (MSH, PID, PV1, OBR, OBX segments)
• FHIR R4 resource extraction (Patient, Observation, Condition, MedicationRequest)
• HL7v2 → tabular (CSV/DataFrame) conversion
• FHIR Bundle iteration and flattening
• Data quality checks (completeness, date validation, code system verification)

Out of scope: HL7v3/CDA parsing, FHIR server deployment, SMART on FHIR authentication, real-time message routing.
