Healthcare data is not all the same. Some data is very organized, like lab results saved in standard formats. Other data is not organized, like doctors’ notes, medical pictures, or scanned papers. The format of data also changes depending on where it comes from. Administrative systems, clinical notes, X-ray images, billing software, and patient monitoring devices each have their own ways of saving data.
The main types of data are:
Bringing all these different types of data into one healthcare platform is needed to create a “single source of truth.” But this is not easy and causes many problems.
Many IT teams say that a big problem is “data silos.” This means different departments or technologies keep data in separate places that do not talk to each other. These silos make workers spend a lot of time looking for information that is scattered across systems. Sometimes up to 30% of their time is used searching. When data is hard to reach, decisions take longer, and patient care can be affected.
Healthcare collects a huge amount of data every day. Platforms that join this data must handle big amounts of information that come in many formats. About 80% of healthcare data is unstructured, which is harder to sort and study. Mixing structured and unstructured data while keeping things correct and easy to use needs strong technology and advanced ways to process data.
Different healthcare systems may use the same words but mean different things. For example, terms like “admission date” or “treatment code” might mean different things or be written in different ways in different systems. This causes problems when trying to combine data.
To fix this, healthcare groups must use smart data mapping methods and follow standard terms like SNOMED CT or LOINC. These standards help match meanings across different data sets so information makes sense.
Many healthcare providers still use old systems that handle important patient data but are not easy to connect with new platforms. Linking these old systems to new unified data platforms takes special technical skills to avoid losing or damaging data.
Putting data together is not just about collecting it. The data must be clean, correct, and consistent. This supports accurate analysis and uses like AI. Healthcare data can have mistakes, missing parts, or repeats. Bad data can lead to wrong decisions, billing mistakes, and harm to patients.
Healthcare data is very private and protected by laws like HIPAA. When data comes from many sources, there is a higher risk that unauthorized people could see it. Safeguards like access controls and secure data transfers are very important to follow the law and keep data safe.
Anne Neuberger, a U.S. security advisor, says cybercrime could cost over $23 trillion by 2027. Because of this, healthcare systems must build strong security into their data platforms.
Healthcare organizations use different ways to join data:
This is a traditional method. Data is taken out of source systems, changed into a common format, then loaded into a data warehouse or platform. ETL usually works in batches and is used mostly for structured data.
ELT works differently. It quickly loads raw data into cloud platforms, then changes it afterward. This method is faster and more flexible. It helps manage big data and unstructured data better.
Data virtualization does not move data physically. Instead, it creates a virtual layer that combines data from different sources in real time or close to real time. This lets users make live queries and get answers faster. But it needs careful tuning to work well.
To make joining data work well and last, healthcare leaders should follow these steps:
Before starting, it is important to know what data is needed for operations, billing, law compliance, and analysis. Clear goals help decide which data to include and how deeply to integrate. This stops the process from becoming too complex.
Unified platforms keep all types of data—structured, semi-structured, and unstructured—in one place. This reduces data silos and repeated work. All teams can access the same cleaned and organized data.
A data catalog collects metadata, business terms, and data dictionaries in one place. This helps standardize definitions for everyone. Ontologies are lists of terms that help connect data with different meanings. These tools keep data meanings clear and matched across the system.
Managing a unified data platform needs a team that includes:
Having the right team helps handle the technical challenges and law rules.
New data platforms change how work happens. Training and clear talks help workers learn new tools and understand why they are important. This makes new systems easier to use.
As healthcare data grows, integration must grow too. Systems that can expand and handle batch and real-time updates keep working well and prevent delays.
Artificial Intelligence (AI) used with unified data platforms can improve healthcare work. AI can help front desk workers and clinical staff by doing some tasks automatically. AI learns from patient data combined in one system and can speed up and improve work.
An example is AI-driven phone systems. Front desk staff handle calls, make appointments, check insurance, and answer benefit questions. These tasks take time and can cause mistakes or delays.
AI virtual assistants trained on all patient data can answer calls and check claims automatically. This lets staff focus on more complex work and patient care.
For example, AI can check patient insurance benefits in real time by looking at payer databases and patient records. This cuts down wait times and reduces hold-ups.
Besides phone work, AI can help clinical decision-making and managing daily operations. AI can find patterns in unified data and predict risks. It gives real-time updates on patient health, clinic schedules, and resource use.
Most IT leaders expect AI to help developers do their jobs faster. With more IT requests happening, automating routine data jobs means systems update more quickly and problems get fixed faster.
Using AI with healthcare data needs strict privacy care. AI must follow laws like HIPAA. It must use data only with patient consent and keep information confidential.
Medical leaders and IT managers in the U.S. face some special challenges:
Because of this, using unified data platforms with strong rules, security, and help from vendors for AI automation can make operations work better and improve patient care.
Bringing together different healthcare data into one platform is important for U.S. medical practices to work well. Problems like data silos, different meanings, old system connections, data quality, and privacy must be fixed using modern tools, skilled workers, and good management.
AI automation for tasks like phone answering and benefit checking can reduce work and help patients.
By following these good practices, healthcare providers can make the most of their data to meet patient and business needs.
A unified data platform receives, stores, cleans, and manages data from diverse systems like e-commerce platforms, ERPs, CRMs, CMS, mobile apps, data warehouses, and data lakes. It addresses data silos by providing a single source of truth accessible to all teams, improving operational efficiency and productivity. It can ingest both internal and external data, enabling employees across departments to utilize harmonized, clean data.
Data warehouses primarily store structured data for reporting and analytics. In contrast, unified data platforms integrate structured, semi-structured, and unstructured data. They support advanced analytics and AI applications, making the data more versatile for modern use cases beyond traditional storage.
A unified data platform typically consists of three layers: data collection (ingestion) through batch or streaming methods; data integration involving normalization and harmonization of structured and unstructured data; and an analytics and AI layer, where clean data supports predictive models and AI agents that can act autonomously.
Data ingestion can occur via batch ingestion, which moves data in bulk (e.g., ETL), streaming or near real-time ingestion that creates virtual views without copying data (zero copy), or bidirectional federation allowing simultaneous access to data from multiple systems without duplication.
In healthcare, unified platforms enable AI agents to work on harmonized patient data, automating tasks like verifying patient benefits, reducing administrative burdens, enhancing patient flow, improving care coordination, and supporting real-time insights—ultimately increasing operational efficiency and patient satisfaction.
Unified, clean, and harmonized data create the context needed for AI models to generate accurate predictions and for agentic AI to act autonomously based on environmental perception, such as managing customer orders or automating services, thus improving decision-making and operational workflows.
Common challenges include integrating heterogeneous and siloed data, especially unstructured data; dealing with legacy systems; ensuring data governance, security, and privacy compliance; managing human factors such as user training and change management; and handling the complexity of scalable, flexible architecture design.
They must enforce strict access controls, protect data from unauthorized access, comply with privacy regulations by obtaining consent and respecting data deletion requests, continuously monitor policies, and maintain data integrity and compliance to build user trust and prevent breaches—critical in sensitive sectors like healthcare.
Managing a unified platform requires data architects for design, data engineers for building and maintaining pipelines, platform administrators for operation, and experts in data governance and security to ensure compliance and data health across all integrated sources and users.
Organizations should define clear business objectives and data needs, audit existing data sources, design future data architecture collaboratively, choose between in-house or vendor solutions, plan integration technologies and workflows, provide thorough training to users, and continuously monitor and optimize the platform as data volumes grow.
