Lung Cancer
The Lung Cancer OMOP CDM dataset was derived from routinely collected electronic health records and hospital cancer registry data from three tertiary hospitals and one regional cancer center in Country X, covering the period 2016-01-01 to 2024-12-31. Source systems included inpatient and outpatient EHR modules (diagnoses, procedures, medications, labs, pathology, imaging summaries) and the institutional tumor registry. Data were transformed to OMOP CDM v5.4 using a documented ETL pipeline (SQL + Python) with concept mapping to SNOMED CT (YYYY-MM release), RxNorm (YYYY-MM), LOINC (YYYY-MM), and ICD-10-CM (2024). Data quality checks were performed with OHDSI Achilles and the Data Quality Dashboard (all critical checks passed; non-critical conformance warnings documented).
