Data plays a bigger role in healthcare every day. Whether it’s helping doctors spot early warning signs of illness or giving researchers a clearer picture of population health, data is now central to how care is delivered, measured and improved.
The problem is, in most health systems, data doesn’t flow easily. It’s often stored in disconnected systems and standalone silos, inaccessible to those who need it. Clinicians are left without the full picture. Patients don’t always know what data exists about them, or where that data is held. Opportunities to improve care or spot potential risks early are missed.
To move forward, we need to unlock healthcare data, securely, ethically, and with patients in control.
The Value of Healthcare Data
Healthcare data isn’t just for record-keeping. It can help prevent illness, improve decision-making, and make healthcare more personal.
Take predictive analytics. When used well, it can identify patients at risk of complications or readmission, allowing clinicians to step in early. Data also enables more targeted treatment plans, shaped by a person’s history, genetics, or how they responded to past interventions.
A good example of this in action is Ireland’s ICU Clinical Audit System (ICU-CAS), which gathers data from every HSE intensive care unit in the country. That data is benchmarked through the UK’s ICNARC, giving ICU teams a clearer picture of performance and patient outcomes and allowing them to improve how care is delivered.
The World Economic Forum has pointed out how health data is also improving systems as a whole, helping to cut waste, reduce duplication, and improve access.
Patients Should Have Control Over Their Data
For too long, healthcare data has been treated as something only care providers hold. However, it is the patient’s data, and they should be able to see it, understand it, and decide who else can access it.
This isn’t just a matter of principle. When patients can view and manage their own records, they tend to be more involved in their care. They ask more questions, understand their options better, and make decisions that lead to improved outcomes. The OECD has documented this link between access and engagement.
Legal protections like GDPR already give people the right to see their data. But in practice, access is often difficult. Many records are stuck in systems that aren’t built for sharing. Giving patients simple, digital access to their records, no matter where they received care, is the next step. The EHDS Regulation entered into force in March 2025 and marks the transition period for breaking down barriers and the emergence of genuine healthcare data sharing across the EU.
What’s Holding Us Back
There are a few reasons why healthcare data isn’t as accessible or useful as it could be.
First, there’s fragmentation. Hospitals, GPs, labs, and community services often use different systems that don’t intergrate well together. That makes it hard for a patient’s information to move with them and flow between different care providers.
Then there’s the question of privacy. Health data is sensitive, and it needs to be protected. Regulations like GDPR (in Europe) and HIPAA (in the US) exist for good reason—but complying with them requires strong systems, clear consent processes, and good governance.
Finally, there’s the key issue of integration and date exchange standards. If one system labels a medication one way, and another does it differently, it becomes harder to share information safely. This is why international standards like HL7 FHIR and GS1 are so important when it comes to integration and healthcare data exchange. Data standards are critical as they help to ensure that disparate systems can truly integrate and communicate information seamlessly.
The World Health Organization has flagged interoperability as one of the biggest gaps in digital health. Without it, real-time care coordination and data-driven planning remain out of reach.
What’s Possible When Data Works
When data is accessible and well-structured, it improves care across the board:
- Patients get more personalised treatment and fewer delays. They also avoid repeating tests or explaining their medical history over and over.
- Clinicians have better information, less paperwork, and more time to focus on direct patient care.
- Researchers and health planners gain access to reliable, anonymised data that can guide public health efforts and speed up innovation.
During COVID-19, data played a central role in managing the crisis. But it also exposed how unprepared many systems were to share information quickly and securely. That moment should be a turning point. Having said that, the pandemic showed us just how quickly solutions can be implemented when there is full commitment and resources available. Take HealthMail for example. Nowadays, HealthMail is a key tool for communicating securely between healthcare providers. Whether it is a GP or Hospital sending an ePrescription to a community pharmacy, it has become a staple when it comes to healthcare data communication between care providers. The speed at which HealthMail was implemented shows just what is possible with the right resources, urgency and commitment across the board.
The Role of Technology
Technology alone won’t solve everything, but it’s a big part of the solution.
- Electronic Health Records (EHRs) give clinicians access to a fuller picture of a patient’s care history.
- Data-sharing platforms help move information between hospitals, GPs, and other services so the patient doesn’t have to.
- Blockchain can play a role in tracking who’s accessed data and when, adding a layer of transparency.
- AI and analytics, as discussed by MIT Technology Review, are already helping to sort through large datasets and support clinical decisions, but only when the data feeding them is accurate and complete.
In Ireland, projects like the rollout of Individual Health Identifiers and work toward a national Shared Care Record are laying the groundwork for better data use.
Getting the Ethics Right
As more data becomes available, we need to make sure we’re using it fairly and transparently.
- Patients need to give real, informed consent—not just click through a form.
- AI tools need to be explainable, especially when they’re influencing diagnosis and treatment.
- Everyone needs to be included, no matter their background, language, or level of digital access.
The WHO has published guidance on the responsible use of AI in healthcare, calling for human rights and transparency to be baked into every system from the start.
What Comes Next
We’re already seeing a shift toward more open, patient-driven data systems:
- The European Health Data Space (EHDS) Regulation is set to empower individuals to access, control and share their electronic health data across the EU.
- Platforms like Apple Health Records allow patients to carry their own medical data.
- Wearables and remote monitoring tools feed information back to care teams in real time.
- Initiatives like OpenSAFELY are helping researchers access anonymised data without compromising privacy.
The EHDS will:
- Empower individuals to access, control and share their electronic health data across EU borders for the healthcare delivery (primary use of data)
- Enable the secure and trustworthy reuse of health data for research, innovation, policy-making, and regulatory activities (secondary use of data)
- Foster a single market for electronic health record (EHR) systems, supporting both primary and secondary use across the EU.
The development of the European Health Data Space regulation is set to make cross-border data sharing a reality across the EU, while keeping patient privacy front and centre.
This is the direction healthcare is heading. But it will take clear policies, trusted systems, and shared commitment to get it right.
Prioritising Patients
Unlocking healthcare data isn’t about chasing buzzwords or building flashy dashboards. It’s about giving patients better care, clinicians better tools, and health systems better insight into what works and what doesn’t.
To get there, we need cooperation, between policymakers, technology leaders, care providers, and patients themselves. We need to build systems that don’t just store data, but make it useful, safe, and available when it’s needed.
And above all, we need to remember what’s at stake: a healthcare system that is more informed, more connected, and better equipped to look after people, wherever they are, and whenever they need it.
