Statement of Work (SOW) / Performance Work Statement (PWS)

The goal is to aggregate and index VA-housed healthcare data for research purposes, enabling in-house researchers and data scientists to easily utilize this data. The system aims to reduce friction in accessing scattered datasets and accelerate the development of precision medicine tools for Veterans.

This procurement covers computing services to build a database containing a manifest of available data, with a deployed web interface for selecting and downloading datasets or subsets for research. The software is custom and intended for use on a dedicated Research Scientific Computing Device (RSCD) outside the VA network. The vendor will use publicly available data for creation, and all testing will be conducted by VA personnel.

Key tasks include:

• Ingestion & Preprocessing: Handling manifests, extracting identifiers, normalizing data across modalities (CT, MRI, digital pathology, bloodwork, test results).

• Data Harmonization: Merging patient data, resolving discrepancies, linking imagery, and adding derived fields.

• Database Layer: Defining SQL schemas and implementing a direct-to-database loader.

• Web-Based Exploration UI: Building a browsable patient index with filters, visualizations (charts, histograms), and a patient record viewer/selector.

• Data Export: Providing an interface to select data, a "checkout summary" with statistics, and options for network drive access or direct download. This includes exporting a manifest file and creating symlinks on a network drive.

• Deployment & Testing: Containerizing the system (Docker/Podman), performing unit and integration tests, deploying on RSCD, and providing user documentation.

• The software is expected to be completed within 120 days.

• Weekly progress meetings will be held.

• Evaluation will involve ingesting public data, running on VA datasets, and manual accuracy checks.

• The final software must pass all evaluation steps.

• Period of Performance: Until delivery, estimated within 120 days of contract start.

• Place of Performance: Contractor's site.

• Contract Type: Firm fixed price.

• GFE/GFI: None.

• Security Requirements: Apply.

• Technology Stack: Backend (Python, SQLAlchemy, SQLite/PostgreSQL), Frontend (Flask, Bootstrap, Plotly), Deployment (Docker/Podman).

• Data Pipeline: Anonymize → Ingest → Preprocess → Store → Explore → Select → Export.
