Why your medical organization cannot sustain far without a healthcare data warehouse?

Medical organizations are using vast amounts of healthcare data to address problems with care quality, healthcare costs, patient satisfaction, and operational inefficiencies.

Healthcare providers are setting up their own data warehouses due to the demand for healthcare analytics. Organizations eventually use data through data warehousing technologies to enhance clinical outcomes, patient experiences, and administrative tasks

The complexity of data warehousing procedures and the sheer volume of diverse healthcare data sources make it difficult to develop data warehouses in the healthcare sector. Therefore, DWH projects in the healthcare industry frequently require years to complete and come at a high cost.

A lot of data are handled by healthcare providers. This data is frequently stored among numerous outdated systems with poor interoperability. Data inconsistencies not only take up doctors’ time (estimate: nine hours per week), but they also affect the standard of care. You know it better than anyone: the first step to a proper diagnosis and efficient treatment is to paint a complete picture of what a patient has and is experiencing in terms of their health.

Medical organizations have long relied on data management and data analytics providers to combat healthcare data disparities. What is the goal? Bring siloed data into a single, consolidated storage location — a healthcare data warehouse — and use it to generate insights.

In order to streamline and simplify the development of complex data warehouses, this blog introduces the fundamentals of the healthcare data warehouse, including DWH architecture design, key features, and a beginner’s roadmap for its implementation.

What is a healthcare data warehouse?

A healthcare data warehouse acts as a central repository for all the medical data gathered from various sources, including wearables, radiology and lab databases, enterprise resource planning systems, and electronic health records (EHR). The data in the warehouse is transformed to fit unified formatting so it can be used for analysis without further preparation.

  • Hospitals and other medical institutions can profit from improved reporting opportunities for internal management and external audits, including regulatory compliance checks.

The Architecture of Data Warehouses for Healthcare Providers

Understanding a healthcare data warehouse’s fundamental layers is essential before developing one. The following layers make up an architecture for an enterprise data warehouse that can meet healthcare intelligence and analytics needs:

Data Source Layer

This consists of internal and external data sources that contain information important to healthcare providers. The various types of data used in healthcare can come from sources like ERP systems, EHR reports, radiology reports, prescriptions, CRM systems, claim management systems, and surveys.

Staging Layer

Data from the various data sources are processed and stored temporarily in a staging area. Here, large swaths of data are transformed, cleaned up, and prepared using ETL (extract, transform, and load) processes for centralized storage and analysis.

Data Storage Layer

Data storage serves as a centralized location to store data that has been loaded using ETL and ELT procedures. It stores and maintains structured data for reporting and analytics. Data marts, which are DWH subsets created for particular business sectors like HR, Finance, Technology, Operations, etc., can also be carried by the data storage layer.

Analytics and Reporting Layer

Data analytics and business intelligence tools are used in this last layer to extract useful information from data. With the help of detailed reports, visualizations, graphs, charts, and summaries, BI tools can access data from the healthcare data warehouse and share analytics and insights.

Key features of a Healthcare Data Warehouse

In order to deliver healthcare and provide patient-centered care, providers can adopt a value-based strategy with the help of a strong healthcare data warehouse. The healthcare DWH must, however, adhere to certain standards in order to be effective. Furthermore, due to the sensitive nature of this information, it must be handled with care and accuracy.

Here are a few essential features that every healthcare data warehouse needs to prioritize.

Key features of a Healthcare Data Warehouse

 Data Warehouse Performance

Fast querying and retrieval of data that is ready for analysis are essential capabilities of full fledge healthcare data warehouses. The following characteristics show how well data warehousing processes work:

Powerful parallel processing

Data warehouses can divide labor-intensive querying tasks into manageable, parallel-processable units with the help of parallel processing.

Data Warehouse Automation

Powerful data warehouse automation tools, like Astera DW Builder, can automate entire data pipelines within a DWH architecture to decrease time-to-market. With automation, data is processed and transferred automatically by the data warehouse from the source to the data storage layer. By doing this, healthcare users are guaranteed timely access to crucial data without having to rely on the time-consuming manual updating of the data warehouse.
