What is eHealth?
eHealth is the collective term for the use of digital technology and communication tools to support, improve or make healthcare more accessible. It does not refer to one specific application, but to a wide range of digital tools that connect healthcare professionals and patients with each other and with healthcare data, from simple communication apps to complex systems for remote monitoring.
eHealth is often mentioned alongside terms such as telehealth and healthcare domotics, but it is broader: telehealth (care provided remotely) is one form of eHealth, as are digital patient records and clinical decision support software. What all these applications have in common is that personal health data is collected, processed or shared, often outside the physical walls of the healthcare organization itself.
eHealth in practice: examples
eHealth applications come in many forms. Some common examples in Dutch healthcare include:
• Telemonitoring: remotely monitoring vital signs such as heart rate, blood pressure or glucose levels, for example in patients with chronic conditions.
• Video consultations: consultations with a GP, specialist or mental health professional via a secure video connection instead of a face-to-face appointment.
• Patient portals: environments where patients can access their own medical records, test results or appointments.
• Electronic health and patient records (EHRs): digital storage and access to medical data, often accessible to multiple healthcare professionals at the same time.
• Mobile healthcare apps: for medication reminders, lifestyle coaching or tracking symptoms.
• Wearables and sensors: devices that collect health data outside the healthcare organization, for example at home.
What these examples have in common is that they all rely on an IT environment that must be continuously available, interoperable and secure, often outside regular office hours and often involving multiple parties sharing data.
Why eHealth requires a scalable, secure Cloud
The more healthcare services become digital, the greater the dependency on the underlying IT infrastructure. An outage affecting a patient portal or EHR is not just an IT issue; it can directly impact the delivery of care. At the same time, the amount of data being collected and shared is increasing, for example between a hospital, a home care organization and a patient who sends measurements through an app.
Cloud infrastructure provides the scalability and availability that eHealth applications require, but it also brings responsibility: where is the data stored, who has access to it, and does the infrastructure meet the requirements that specifically apply to healthcare? This is precisely where the NEN 7510 standard comes into play.
What does this mean for patient data in the Cloud?
When a healthcare organization hosts eHealth applications partly or entirely in the Cloud, some responsibility for information security shifts to the Cloud provider, but ultimate responsibility does not. Under the GDPR, the healthcare organization remains responsible for protecting patient data, even when that data is entrusted to an external party. Choosing a Cloud partner that is itself NEN 7510 certified, and documenting this in a data processing agreement, is therefore an important step in the organization's own compliance process.
In practice, this involves measures such as encrypting data both at rest and in transit, strict access controls for systems containing patient data, and logging who accessed which data and when. The latter is also addressed by the additional NEN 7513 standard. The physical location of the data also matters: Cloud infrastructure that runs entirely in Dutch data centers and is subject to Dutch law makes it easier for healthcare organizations to demonstrate that their data remains under control.
