Healthcare Data Warehousing on Amazon Web Services (AWS)
Healthcare Data Warehouse: the Essence
A healthcare data warehouse (DWH) helps collect healthcare data from disparate sources into a centralized repository, process and structure it for analytical querying and reporting.
A healthcare DWH ingests large volumes of data from a wide variety of data sources, including:
Achieves high healthcare data accuracy and consistency.
Improves healthcare data trustworthiness and timeliness.
Reduces the complexity of the healthcare data environment while meeting security and compliance needs.
The healthcare DWH becomes a solid foundation for further analytics initiatives targeted to achieve the following goals:
Data management and integration
- Integration of all healthcare data types (structured, semi-structured, unstructured).
- Big data ingestion.
- Streaming data ingestion.
- Integration of healthcare data with ETL/ELT processes.
- Full and incremental healthcare data extraction/load.
- Healthcare data transformation of varying complexity (data type conversion, summarization, etc.).
- SQL-based healthcare data querying.
- Integrated, summarized, subject-oriented healthcare data storage.
- Storing current and historical healthcare data.
- Metadata storage.
- Storing data oriented to a specific administrative (HR, accounting, etc.) or medical department (radiology, intensive care, pediatrics, etc.) in data marts.
- Protected health information (PHI) storage.
- Elastic scaling of storage and compute resources.
- High performance query processing.
- Materialized view support.
- Result caching.
- Performance and concurrency dynamic management.
- Automated infrastructure provisioning.
- Automatic backup of healthcare data.
- Fault tolerance.
Security and compliance
- Healthcare data encryption at rest and in transit.
- Granular row- and column-level security control.
- Dynamic healthcare data masking.
- External healthcare data tokenization.
- Network isolation.
- Compliance with healthcare regulations (HIPAA, FDA, HITECH, etc.).
A data lake – Amazon Simple Storage Service (Amazon S3)
Amazon S3 may serve as an economical long-term storage for structured (e.g., claims data, EHRs) and unstructured (radiology images, audio/video recordings, streaming healthcare data from wearables and devices, etc.) data at any scale before data is queried by the DWH.
Self-service BI software – Amazon QuickSight
Self-service ML-powered BI service, which facilitates quickly delivering business and medical insights to the decision-makers in the form of immersive reports and interactive dashboards.
Machine learning (ML) software – Amazon SageMaker
To train ML models on structured healthcare data from the data warehouse and enable advanced analytics to predict clinical outcomes, deliver proactive patient care, improve healthcare scheduling, monitor supply chain, make grounded decisions about hospital spending, etc.
Proof of Concept
We help you validate your healthcare DWH solution with a tailored PoC to better understand its potential and get real-life user feedback.
Healthcare DWH scalability and flexibility
With a custom healthcare DWH solution design, we ensure your ability to instantly upload any type (structured, semi-structured, unstructured) and amount of healthcare-related data to efficiently address changing data analytics objectives.
Focus on security and healthcare data protection measures
To allow you to store and process healthcare data within the secure HIPAA-compliant environment and safeguard sensitive patient data, we select and customize the technologies enabling all-time data encryption and dynamic data masking, design data access policies, set up multi-factor authentication, etc.
Leveraging AWS technologies, ScienceSoft helps healthcare organizations build fast, highly scalable, and cost-effective DWH solutions, which ingest all types (structured, semi-structured, unstructured) of healthcare data, instantly process and store it in a highly-secure HIPAA-compliant environment.
