From Siloed Systems to Seamless Care: Why Interoperability Matters

The way we store and share health data is broken. Despite decades of digitization, healthcare data remains stuck in silos—fragmented across hospitals, labs, specialists, wearable devices, and electronic health records (EHRs). These disconnected systems slow down diagnoses, introduce opportunities for medical errors, and often lead to inefficient or even harmful treatment paths. For patients, this means repeating medical histories, duplicating tests, or worse—being misdiagnosed because a critical piece of their health puzzle was missing.

Interoperability—the seamless exchange of information between systems—isn’t just a technical goal. It’s a patient safety imperative.

The Cost of Fragmentation

Data silos are more than an administrative nuisance. In fact, nearly 70% of adverse health events are tied to communication and data flow breakdowns, according to healthcare safety reports. For example, a patient seeing a specialist may not have their medication history updated from a general practitioner’s office, increasing the risk of potentially inappropriate prescriptions or dangerous drug interactions. Similarly, researchers conducting longitudinal studies often face major delays in aggregating multi-source data, which slows down insights and medical discovery.

Without interoperability, every stakeholder in healthcare operates with a limited view—patients, clinicians, and researchers alike.

The Case for Connected Health

When systems talk to each other, care improves. Interoperability allows real-time health data—from wearables, lab reports, patient input, and clinical records—to flow securely and instantly between approved parties. Clinicians get a holistic view of the patient, which supports faster and more accurate diagnoses. Patients experience less frustration and more personalized care, and researchers can access high-quality data without jumping through endless recruitment and reconciliation hurdles.

Interoperability also enables innovation. By breaking down barriers, it becomes possible to build predictive models, apply AI-driven insights, and introduce smart alerts and nudges to both patients and care teams, all of which are grounded in data that is timely, relevant, and comprehensive.

SentNotes: Enabling Seamless, Secure Collaboration

SentNotes is built with interoperability at its core. Our platform connects wearable data, patient-reported outcomes, and clinical information into a single, user-controlled environment. Unlike legacy EHR systems or standalone apps, SentNotes doesn’t just collect data—it contextualizes, translates, and shares it where and when it matters most.

Through smart contracts, data access is governed by consent, ensuring security and transparency. Patients decide who sees what, and when. Clinicians get real-time, longitudinal data views, while researchers gain structured access to anonymized, research-ready datasets—without compromising privacy or ethics.

A Europe-Ready Solution

In Europe, the push toward value-based care, GDPR compliance, and cross-border health data access makes interoperability a strategic necessity. SentNotes aligns with these shifts, offering a scalable solution that respects privacy while enabling impact. Whether in Hungary’s fragmented specialty care environment or across EU-wide research collaborations, SentNotes is ready to bridge the gap.

Healthcare should never be a puzzle of disconnected pieces. With interoperable systems, we connect the dots—improving care, accelerating research, and empowering every stakeholder along the wa
