# Project Status Summary
**Last Updated:** June 28, 2026

## 1. Data Migration & ETL Status: **100% Complete**
All legacy MySQL data and live Supabase data (post-March 2026) have been successfully extracted, transformed, and loaded into the target OMOP database.
- **PERSON**: 120,087 patients loaded.
- **VISIT_OCCURRENCE**: 32,028 visits loaded.
- **NOTE**: 996,274 clinical notes loaded (de-identified).
- **CONDITION_OCCURRENCE**: 135,416 diagnoses loaded.
- **DRUG_EXPOSURE**: 1,188,463 prescriptions loaded.
- **MEASUREMENT**: 5,113,411 lab results and vitals loaded.
*Total clinical records migrated: 7,585,679*

## 2. Vocabulary Loading: **100% Complete**
The OHDSI standard vocabularies (SNOMED, RxNorm, LOINC, ICD-10, etc.) downloaded from Athena have been fully parsed and loaded without any out-of-memory errors.
- **CONCEPT**: 6,609,843 records loaded.
- **CONCEPT_RELATIONSHIP**: 41,353,078 records loaded.
- **CONCEPT_ANCESTOR**: 78,416,259 records loaded.

## 3. Database Constraints & Integrity: **100% Complete**
All foreign key and primary key constraints on the clinical tables have been successfully applied and are currently active. 
- Clinical constraints were resolved by inserting safe default placeholders (e.g., `provider_id = 0`, `care_site_id = 0`) where explicit mappings were absent.
- The `omop_constraints.sql` script ran to completion.
- Verified active constraints on all 6 clinical tables (`person`, `visit_occurrence`, `note`, `measurement`, `drug_exposure`, `condition_occurrence`). The database now has **100% standard database integrity**.

## 4. Next Steps
The ETL, vocabulary, and integrity phases are fully finished. The immediate next step is:
**Run Achilles Profiling:** We need to set up and run the OHDSI Achilles tool against the target database to generate descriptive statistics, data quality reports, and validate the overall clinical dataset.
