Not so long ago, maintaining professional databases was a nightmare for many. It involved extensive storage spaces filled with files that sometimes could take ages to locate - not to mention if misfiled. And when it comes to medical services, the lack of efficiency can affect the outcome in the costliest possible way. That’s where a healthcare data warehouse enters the game.
The need to create digital medical databases first came to light during the early 1990s. Medical workers recognized its capacity as a valuable resource for management and clinical research. However, due to privacy and other concerns, the innovation was adopted by many other industries before finding its way to healthcare.
So, What Is Data Warehousing in Healthcare?
Briefly put, data warehousing in healthcare is the most efficient file management system there is. It allows for storing, organizing, and handling vast amounts of information, from patients’ clinical histories and lab tests to insurance records and financial reports. It also minimizes the risk of human error and keeps the files secure.
If you are new to the world of digital data management, just imagine a giant, fully automated library that operates at light speed. Both comprise endless rows and columns of neatly stacked folders, color-coded and marked by letters, numbers, and signs.
The main difference between a perfectly organized physical library and a digital warehouse is functionality. The latter is capable of searching and integrating data from various sources all at once. Simultaneously, it performs complex analytics, supports administration, and helps identify weak links and areas with potential for improvement.
Properly designed medical data software can compute and solve tasks within seconds, saving plenty of time you can invest in maintaining and improving the quality of service.
Good to know: Although they might sound synonymous at a glance, a clinical repository and a healthcare data warehouse are not the same thing. The clinical repository holds only clinical data, like patient records. Conversely, the data warehouse is a central repository that keeps, more or less, all kinds of files involved with the clinic’s operation.
Let’s now dive deeper into details and explore the benefits, features, and cost considerations of healthcare data warehouses.
Benefits of Data Warehousing in Healthcare
A healthcare data warehouse can be your most helpful tool for improving your medical business, making the best use of all information available. Centralized files and automated processing allow you to gain quick, sharp insights, optimize resources, and make well-informed decisions.
Here is an overview of the most important advantages.
Improved Data Accessibility
We have already mentioned that a healthcare data warehouse resembles a giant library, which means all information resides in one place. Thanks to advanced organizing systems, it’s easy to find and use. A patient’s medical history, treatment records, and diagnostic processes, as well as administrative files—you can obtain anything within seconds. Such a rounded, encyclopedic picture allows you and your medical staff to provide the highest level of service in return.
In other words, by analyzing all available data, you can improve the accuracy of diagnosis and chances of therapy success. The ease of access also helps medical researchers to identify trends and develop new treatments.
Enhanced Data Analytics
The fans of Doctor House will remember how much diagnostics sometimes resembles detective work. A healthcare data warehouse is like a box of clues that pave the road to finding a reason why a patient is sick. The database contains details about the patient’s lifestyle, family history, habits and weaknesses, food and exercise info, allergies, and more. What’s best, it’s already completely set, systematized, and ready to use.
Through data analytics, you can track the clues and identify patterns that lead to the correct conclusions about patients’ conditions.
Scalability and Flexibility
Many clinics and medical businesses start small but grow fast. When the patients become regulars, their files grow with every visit, and so does the clinic’s administration. Healthcare data warehouses can grow (or shrink, if necessary) to follow the development. Many tools can be added or omitted according to the ongoing needs.
The possibility of scaling the digital database means you can always have the product optimized to provide maximum convenience.
Data Security and Privacy
The patient’s privacy is holy to ethical practice. With that in mind, healthcare data warehouses are programmed to provide exceptional levels of data security. It involves applying high levels of protection against system breakdowns as well as hacker attacks.
Data warehousing in healthcare involves advanced and up-to-date security measures that keep all information safe from unauthorized access.
Streamlined Operations
The bigger the clinic gets, the more diverse services it provides, and your need for efficient data administration rises exponentially. A database warehouse in healthcare helps you optimize appointment scheduling, which will reduce waiting times and improve the patients’ experience in return. Moreover, it takes over the hassle of inventory management. Usage tracking makes it possible to alert the staff before a supply runs out and prevent shortages. And in terms of financial planning, the system can analyze the processes and patterns to identify the room for improvement.
Due to its solution-oriented analytic capabilities, data warehousing pinpoints and optimizes every aspect of medical business.
Predictive Analytics and Machine Learning
A giant, systematized database assists doctors in tracking down the underlying threats to the patient’s health. It recognizes potentially problematic habits, patterns, and genetic predispositions that might trigger a disease in the future. Knowing the risks helps you advise and take steps to prevent it from happening. On a larger scale, predictive analytics can also anticipate massively contagious outbreaks, such as seasonal flu, and prepare for it in advance.
By collecting, organizing, and analyzing copious amounts of information, a warehouse database helps you prepare and react before the events occur.
Key Features of Healthcare Data Warehouse
Data Integration
Accumulating and integrating many kinds of data from diverse sources is fundamental for healthcare data warehousing processes. That includes:
- Electronic Medical Records (EMR)
- Electronic Health Records (EHR)
- Enterprise resource planning systems (ERP)
- Lab databases
- Public health databases
- …and much more.
Data integration enables keeping all valuable information in one place, which in return helps with overviews and predictive analytics.
Data Cleansing and Transformation
Just like any large, ongoing database, a healthcare data warehouse also needs occasional cleaning and decluttering in order to remain up to date. This is very important for several reasons, starting from removing duplicates, errors, and inconsistencies in available material that could affect predictions or test results. Moreover, the process identifies information holes and marks them for filling up.
After cleaning, the data can be augmented, reorganized into a more optimized form, indexed, and sorted.
Data Governance and Compliance
Data governance is the supervising element of a data warehouse in healthcare, a set of rules determining how to handle the content. It covers the whole information cycle, from creation to the moment it's archived or destroyed. Moreover, as healthcare heavily relies on accurate, reliable information, data government also implements processes that will keep things relevant and establish through access control.
Data Security and Encryption
Apart from access control, extensive security measures involve:
- Encryption
- Firewalls
- Intrusion detection systems
- Regular security audits
- Staff training
- Regulation compliance
- Physical security
A combination of advanced technology, robust backup and recovery plans, education, and physical server security creates an all-rounder network with high-security coverage.
Data Querying and Reporting
Healthcare data warehouse models employ specific tools for querying and presenting information accurately.
- SQL & Query Builders retrieve data necessary for a specific research
- Business Intelligence tools (BI) assist in visualizing maps of complex data
- Data mining tools are used for discovering patterns and relations in large data sets
- OLAP (Online Analytical Processing) supports data interaction for better analyses
- Decision support tools integrate with warehouses to provide specific recommendations
- Reporting software for creating formal tickets on patient’s care
- Self-serving analytics that aid non-technical users
- APIs & Integration tools responsible for real-time data processing and repotting
These tools make it possible to efficiently retrieve, analyze, and report healthcare data, promoting informed decision-making and effective healthcare management.
Costs of Implementing Healthcare Data Warehouse
A range of small and substantial costs are involved between the initial setup and ongoing maintenance of a fully active healthcare data warehouse system. The final sum depends on many factors, starting from the size of the warehouse and its assets.
