With the widespread acceptance of telemedicine, the promise of remote healthcare has become borderless. A patient in one country can consult with a specialist halfway around the world, gaining access to expertise that might not be available locally. For complex diagnoses—like rare cancers or neurological conditions—this kind of access can be life-changing or perhaps even life saving. But behind the convenience and speed of remote diagnosis lies an invisible and increasingly critical issue called data residency.
Data residency refers to the physical or geographic location where health data is stored and processed. At first glance, this might seem like a minor technical detail. On the internet geographic borders seemingly melt away. But for healthcare organizations, patients, and providers operating across country borders, where data “lives” can mean the difference between compliance and violation, trust or skepticism, access or denial of care.
Regulatory Requirements Vary by Country
Healthcare data is one of the most sensitive types of personal information, and many countries regulate it tightly. Better known laws like the EU’s General Data Protection Regulation (GDPR), Canada’s Personal Information Protection and Electronic Documents Act (PIPEDA), and the U.S. HIPAA all dictate how and where patient data can be stored, transferred, and accessed. However, a growing list of other countries have adopted even more stringent controls over its patients’ health records.
Some nations, including the Australia, the UAE, and a host of others, mandate that patient health records must remain within national borders unless special agreements are in place, sometimes even restricting those. This is meant to protect citizens from foreign surveillance, misuse, lack of trust or weaker data protection standards. A hospital or remote second-opinion program that inadvertently stores diagnostic images or case files in the wrong jurisdiction, using non-compliant technology, could face steep fines, even criminal sanctions or be barred from continuing service.
Trust Is Tied to Data Location
Patients are becoming increasingly aware of privacy risks, especially when their most personal details—genetic profiles, imaging studies, pathology reports—are shared digitally. Knowing that data is stored within a trusted jurisdiction helps patients feel more secure in seeking remote consultations. Conversely, if a patient learns their data is transmitted to a country with limited or questionable privacy protections, they may hesitate or refuse to participate.
Healthcare providers, too, need assurance that the systems they use for cross-border diagnosis protect their patients’ rights and institutional reputations.
Clinical Collaboration Requires Legal Clarity and Advanced Technical Architecture
Remote diagnosis is rarely a one-to-one interaction. Multiple specialists, labs, and legal entities may be involved. Data residency helps define who is responsible for safeguarding information at each step. Without clarity, collaboration can grind to a halt, especially if participants come from regions with conflicting legal requirements.
For example, a U.S. physician may be eager to collaborate with a European counterpart on a difficult case, but if the imaging platform used stores data in a country outside the EU, that European provider might be prohibited from participating.
Technology Can Bridge the Gap
This is where technology platforms like Purview play a critical role. Purview’s medical image and record sharing system is designed with data residency in mind, enabling healthcare organizations to store patient information in-region, comply with local regulations, and still provide instantaneous, seamless cross-border access when appropriate. By leveraging cloud infrastructure within regional data centers, Purview ensures that data stays where it is legally required, while encrypted pathways allow authorized providers to view and collaborate securely.
In practice, this means a hospital in the US can confidently provide a second opinion to a patient in Canada without running afoul of Canadian data storage requirements—or vice versa. Patients gain access to expertise, while providers gain peace of mind that they are safeguarding both compliance and trust.
Conclusion
Remote healthcare diagnosis has the potential to erase geographic boundaries for patients in need. But data still is not borderless. Data residency ensures that as we expand access to world-class care and medical specialization, we do so responsibly, securely and in compliance with laws that exist to protect patients. With solutions like Purview making data residency compliance achievable without slowing down care, the future of cross-border healthcare is supported, enabling access to specialized patient care when and where it is needed, without the legal risk of running afoul of where the data (or the patient) lives.
