Wired for Better Health: The Promise, Pitfalls and Potential of Electronic Health Records

In early 2026, the Irish Government approved the HSE to begin procurement for a national Electronic Health Record (EHR), marking a major milestone in the modernisation of the health service. According to the European Commission’s Digital Decade eHealth Indicator Study, Ireland scores just 25% on access to electronic health records, the lowest among the countries assessed, compared with 65% for the Netherlands and 100% for Belgium and Estonia. While the procurement launch is significant, it also highlights how far Ireland still has to travel relative to European peers. International evidence consistently shows that well-implemented EHR systems can improve safety, coordination and clinical outcomes, whereas poorly implemented ones risk cost overruns, clinician frustration and limited patient benefit.

What Is an Electronic Health Record?

An EHR is a comprehensive digital record of a patient’s medical history, maintained over time across care settings. It brings together diagnoses, medications, allergies, lab results, radiology images, vaccination history, clinical notes, and more, all in one accessible, secure system. Unlike the older concept of an electronic medical record (EMR), which was typically confined to a single practice or provider, an EHR is designed to travel with the patient. It is accessible to authorised clinicians in a GP surgery, a hospital emergency department, a community pharmacy, or a specialist outpatient clinic, wherever care is being delivered.

The HSE itself defines an EHR as “a digital version of a patient’s medical record that is designed to be shared between different healthcare organisations, such as hospitals, clinics, and pharmacies,” with the explicit aim of improving care coordination and communication between providers. The goal is deceptively simple: the right information, in the right place, at the right time.

The Benefits: A Well-Evidenced Case

Patient Safety

Decades of implementation across multiple healthcare systems have produced a substantial evidence base. A national survey of U.S. physicians conducted by the Office of the National Coordinator for Health Information Technology found that 94% reported their EHR made records readily available at the point of care, 88% said it produced clinical benefits for their practice, and 75% reported it enabled them to deliver better patient care.

Systematic evidence points in a similar direction. A meta-analysis of 47 studies found that EHR use was associated with reduced documentation time, greater adherence to clinical guidelines, and lower rates of medication errors and adverse drug events. While results varied across settings, the overall trend suggests meaningful gains in safety and clinical performance when systems are implemented effectively.

Clinical Decision Support

Modern EHRs are not passive repositories, they actively support clinical decision-making. Integrated decision-support tools can alert clinicians to medication interactions or allergies, prompt preventive screenings or vaccinations, and surface evidence-based guidance at the point of care. In some systems, advanced analytics can also help identify patients at elevated risk of deterioration before a crisis occurs.

Efficiency and Continuity of Care

For patients with complex or chronic conditions, a unified digital record can significantly improve continuity of care. Without it, clinicians often rely on patient recall, incomplete referral documentation, or manual information-gathering from other providers. Where interoperable records are available, a more complete clinical picture can be accessed rapidly, a factor that is particularly important in emergency settings.

Shared records can also reduce duplication. When prior results are accessible, patients are less likely to undergo repeat tests or imaging simply because earlier information cannot be retrieved. Evidence consistently shows that this can save time and resources while reducing unnecessary procedures.

Population Health and Research

At a system level, mature digital health infrastructures generate rich data that enable services to monitor disease trends, identify high-risk populations, evaluate treatment effectiveness at scale, and allocate resources more strategically. Countries with advanced digital health ecosystems, including Denmark, Estonia and Sweden, have combined interoperable electronic records with national registries to support clinical research, inform public health policy, and strengthen system planning.

The United Kingdom’s response to COVID-19 illustrates this potential. Large-scale analyses of NHS-linked data, including early studies on vaccine effectiveness and risk factors for severe disease, were enabled by established digital health and data-linkage infrastructure. While not dependent on a single national EHR platform, these capabilities relied heavily on digital records being available, standardised and linkable across the system.

Patient Empowerment

EHRs increasingly include patient-facing portals that allow individuals to view their own records, track test results, manage medications, book appointments, and communicate securely with their care teams. This shift toward patient-held records is a central pillar of modern health policy across the EU, driven by the European Health Data Space (EHDS) Regulation, which was published in the Official Journal of the EU in March 2025 and creates the first sector-specific common health data space in Europe. The evidence suggests patients benefit: those encouraged by their provider to use patient portals are significantly more likely to engage with their health data and to report higher satisfaction with their care.

Lessons from Implementation Failures

The UK’s NPfIT

The most frequently cited large-scale EHR failure is the UK’s National Programme for Information Technology (NPfIT), launched in 2002 with the ambition of creating a single nationwide electronic health record system for the NHS. The programme was formally discontinued in 2011 and has often been described as one of the largest public-sector IT failures. Its primary objective, a unified national HER, was never realised. Peer-reviewed analyses have attributed its collapse to a combination of political, organisational and design factors, including insufficient clinical engagement, resistance from NHS trusts, data-privacy concerns and inadequate training. Its highly centralised, top-down implementation model is widely regarded as a major contributing factor. As of May 2022, 27 NHS trusts still lacked a comprehensive electronic patient record system.

Denmark and Finland: The Epic Challenge

Even countries with advanced digital health infrastructure have encountered significant implementation challenges. A 2022 peer-reviewed study in the International Journal of Medical Informatics examining Epic deployments in Nordic health systems found that post-implementation experiences often diverged from expectations. In Denmark, several years after go-live, clinicians reported usability concerns and workflow disruptions, and national reviews criticised aspects of both the business case and implementation approach.

In Finland, surveys conducted during system transitions similarly found that while technical performance sometimes improved, clinicians frequently reported declines in usability and workflow support compared with legacy systems. These findings highlight a consistent lesson from international experience: even in digitally mature environments, large-scale EHR implementations can produce short- to medium-term disruptions before benefits are realised.

The Common Failure Modes

Across the literature on EHR implementation failures, a consistent set of risk factors emerges:

• Clinician resistance and inadequate change management: Healthcare professionals who are not engaged early, involved in system design, or properly trained are less likely to adopt systems effectively. Studies from US academic centres, including Stanford, have found high levels of dissatisfaction and burnout associated with poor EHR usability, with many clinicians reporting reduced efficiency and increased administrative burden.

• Interoperability failures: Healthcare systems often contain dozens of legacy platforms developed over decades. Even where new systems support standards such as HL7 or FHIR, differences in implementation, data formatting, and message structures can create integration problems, leading to missing or duplicated data. The HSE’s Digital Health Strategic Implementation Roadmap has acknowledged significant interoperability gaps across current Irish systems.

• Data migration risks: Transferring data from legacy platforms or paper records is technically complex and prone to error. Incomplete migration can leave clinicians without critical historical information during transition periods.

• Cost overruns and unrealistic timelines: Large-scale health IT programmes frequently exceed initial budgets and schedules. National EHR initiatives in several countries have ultimately cost over €1 billion when full lifecycle expenses are considered.

• Cybersecurity vulnerabilities: Centralised digital systems concentrate highly sensitive personal data. In 2021, a ransomware attack on the HSE disrupted services nationwide and resulted in the unlawful publication of tens of thousands of patient and staff records, with hundreds of subsequent data protection claims filed.

What Success Looks Like: Lessons from the Leaders

Estonia launched its nationwide Electronic Health Information System in 2008. Today, the system covers nearly the entire population and processes millions of monthly queries from clinicians and patients. Around 99% of prescriptions are issued electronically. Researchers attribute Estonia’s success to clear governance structures, strong legal foundations, agreed data standards and access rules, and a digital ecosystem developed over decades. The country’s broader digital public infrastructure, particularly its national digital identity system, has been a critical enabler.

Denmark’s success, reflected in consistently top-tier rankings in European digital health benchmarks, is widely attributed to long-term investment, strong coordination between national and regional authorities, high public trust in data governance, and consensus-driven policymaking. Danish health data legislation requires hospitals to share clinical information with national systems, and almost all prescriptions are issued electronically and accessible through the national patient portal, Sundhed.dk. Crucially, Denmark built its digital health infrastructure gradually over decades rather than attempting a single transformative rollout.

Across countries, the lessons from successful implementations are remarkably consistent: early and sustained clinician engagement; phased implementation rather than “big-bang” deployments; investment in training and change management proportionate to the scale of transformation; interoperability standards defined from the outset; cybersecurity designed into system architecture; and governance structures capable of sustaining political commitment over the long term.

Ireland’s Position

Ireland’s digital health position is stark. In the European Commission’s 2024 eHealth indicator study, Ireland scored 25% on access to electronic health records, the lowest in the EU, compared with 65% for the Netherlands. Until the recent procurement launch, Ireland remained the only EU member state without a national patient-accessible EHR portal.

The reasons are structural and historical. Ireland’s health service has long been characterised by fragmentation, between public and private provision, between acute hospitals and primary care, and across multiple legacy IT systems developed without central coordination. The 2021 ransomware attack exposed these vulnerabilities dramatically, as a system still heavily reliant on paper records was severely disrupted.

Ambitions for a national EHR are not new. The HSE’s 2015 Knowledge and Information Strategy identified EHR capability as essential, and the 2017 Sláintecare report described integrated records as central to reform. However, sustained capital investment did not follow until the publication of the Digital for Care 2024-2030 framework and subsequent government approval of a preliminary business case in 2025. Ireland now faces external obligations under the European Health Data Space Regulation, which requires interoperable digital health records across the EU. Meeting these obligations will require updated primary legislation and sustained implementation over several years.

The Technology Is Not the Hard Part

Electronic health records, at their best, improve patient safety, reduce errors, cut duplication, and enable patients to participate more actively in their care. The evidence base for these benefits is substantial and growing. At their worst, however, poorly implemented systems can consume resources, frustrate clinicians, and fail to deliver meaningful clinical value. The difference between these outcomes is rarely the technology itself. It is governance, engagement, training, realistic timelines, and sustained political commitment. Ireland has, after many years of delay, now begun this journey in earnest. The procurement of a national EHR is a significant and welcome step. But procurement is only the starting point. The harder work, building clinical trust, replacing fragmented legacy systems, ensuring interoperability, safeguarding patient data, and sustaining implementation over many years, still lies ahead.

Countries that have succeeded have done so by treating digital health not as an IT procurement exercise but as a clinical transformation programme requiring the same rigour, patience, and evidence-based discipline that healthcare itself demands. That is the standard Ireland must now meet.
