Clinic Buchinger Wilhelmi - Medical Data Warehouse

Solution Architecture and creation of a data warehouse fulfilling German healthcare regulations, including an ETL pipeline for medical data of the leading fasting clinic, to provide personalised app based suggestions to improve the treatment.

Case Study: Modernizing Data Infrastructure for Buchinger Wilhelmi Fasting Clinic

Client: Buchinger Wilhelmi

Project Overview:

Buchinger Wilhelmi, the world’s leading fasting clinic, sought to enhance their treatment personalization and research capabilities through advanced data management. The goal was to establish a robust data warehouse that complies with stringent German healthcare regulations, specifically the Kliniklandeskrankenhausgesetz, while enabling efficient data processing and personalized app-based suggestions for patients.

Objective:

To architect and implement a secure, scalable data warehouse solution with an efficient ETL pipeline, ensuring compliance with German privacy laws and enabling the clinic to deliver personalized treatment advice and facilitate comprehensive research analytics.

Solution Design Process:

Requirement Analysis:

• Engaged with Buchinger Wilhelmi’s medical and IT teams to understand their specific needs, regulatory constraints, and data processing requirements.
• Identified the necessity for a secure, on-premises solution due to the restrictions on using public cloud providers.

Technology Selection:

• Chose Kubernetes for its robust container orchestration capabilities, enabling autoscaling, load balancing, and efficient resource management on bare-metal servers.
• Selected Prefect as the ETL scheduler for its efficiency and flexibility over traditional tools like Airflow.
• Decided on Minio for S3-compatible object storage, facilitating seamless data staging between ETL steps.
• Opted for PostgreSQL as the final data repository for its reliability and compatibility with analytical tools.

Architecture Design:

• Designed a Kubernetes cluster on bare-metal servers to ensure compliance with German healthcare regulations and provide scalability.
• Implemented a comprehensive ETL pipeline managed by Prefect, orchestrating the ingestion, processing, and transformation of medical data.
• Configured Minio S3 buckets for intermediate data storage, ensuring smooth data flow between ETL stages.
• Established PostgreSQL databases to store the final processed data, enabling easy access for app-based personalized recommendations and research analytics.

Implementation:

Infrastructure Setup:

• Deployed a Kubernetes cluster on bare-metal servers, ensuring high availability, autoscaling, and load balancing to handle varying workloads.
• Configured Prefect as the ETL scheduler, defining and orchestrating the necessary data processing workflows.

ETL Pipeline Development:

• Developed ETL processes to extract medical data, transform it into useful formats, and load it into the data warehouse.
• Utilized Minio S3 buckets for staging data at different ETL steps, ensuring seamless transitions and data integrity.
• Finalized the processed data in PostgreSQL databases, making it available for further analysis and application use.

Data Utilization:

• Integrated the processed data with a personalized app, providing users with tailored fasting recommendations based on their medical data.
• Developed analytical dashboards for the research department and doctors, enabling data-driven improvements in treatment protocols.

Results:

• Regulatory Compliance: Successfully implemented a secure, on-premises data warehouse solution that complies with the Kliniklandeskrankenhausgesetz.
• Enhanced Personalization: Enabled personalized fasting recommendations through a user-friendly app, enhancing patient treatment experiences.
• Improved Research Capabilities: Provided the research department and medical professionals with comprehensive analytical dashboards, facilitating data-driven insights and treatment improvements.
• Efficient Data Processing: Achieved efficient data processing and transformation through the use of Prefect and Minio, ensuring timely and accurate data availability.

Conclusion:

The project resulted in a state-of-the-art data warehouse solution for Buchinger Wilhelmi, leveraging advanced technologies to comply with German healthcare regulations and significantly enhance patient treatment personalization and research capabilities. By implementing a secure, on-premises infrastructure with efficient ETL processes, the clinic can now offer personalized recommendations and drive continuous improvements in fasting treatments.
