In Belgium, a patient’s medical data is not stored in a single location. It is distributed among the general practitioner’s office, hospital records, regional networks (Réseau Santé Wallon, Vitalink, BruSafe+), and federal platforms. Accessing health information online requires understanding this fragmented architecture, its concrete limitations, and the tools that attempt to make it readable.
Health Data in Belgium: Why Access Remains Fragmented
The Belgian system is based on the informed consent of the patient and the notion of a therapeutic relationship. A healthcare professional can only access your data if you have given your consent and a care relationship exists between you. This mechanism protects privacy, but it means that not all your data is visible on a single platform.
The Global Medical File (DMG), managed by your general practitioner, centralizes medical history: vaccinations, hospitalizations, allergies, blood test results. In contrast, the Shared Health File (DSP) on the Réseau Santé Wallon is a separate space, fed by documents that healthcare providers choose to share. The two are complementary but independent.
The ability to consult your information depends on its actual encoding by each caregiver and its sharing on the relevant network. An examination conducted in a Flemish hospital will not automatically be visible on the Walloon portal, and vice versa.
For a patient consulting multiple specialists in different regions, complete access to their own file remains a multi-step process. On portail-sante.be, various procedures and resources related to health in Belgium are gathered to facilitate this navigation.
MaSanté.be: What the Federal Platform Really Allows You to Consult
The MaSanté platform (masante.belgique.be) is the federal entry point. It allows you to consult, via secure identification through itsme or electronic ID, a set of documents and data.
- Open medication prescriptions and the history of pharmacy dispensations (limited to a maximum of one year)
- The health summary (Sumehr), a synthetic document written by the general practitioner summarizing medical history, allergies, and ongoing treatments
- Results of screening tests, shared medical reports, and recorded vaccinations
- Management of consents, care mandates, and provider exclusions
A mobile application is also available on iOS and Android, offering access via itsme to the same features. The platform also allows you to consult your children’s health data up to the age of sixteen.
What is Missing on MaSanté
The portal only displays documents that have been shared by healthcare providers. If your doctor or hospital has not encoded or published a report, it will not appear. The gap between “all your data” and the data actually available is the main limitation of the current system.
The doctor’s personal notes, informal exchanges during a consultation, or certain test results conducted in facilities not connected to the network remain invisible. This situation is explained by the voluntary nature of sharing: nothing obliges a hospital to publish every document on the federal platform.
Digital Health Literacy: An Underestimated Barrier
Having a tool does not guarantee the ability to use it. The SPF Public Health organized an inter-federal symposium in September 2026 dedicated to the accessibility of e-health. The stated goal: to make digital health tools usable by people who are not comfortable with digital technology.
The digital divide affects a significant portion of the Belgian population, particularly the elderly and vulnerable groups. Connecting with an electronic ID or via itsme requires a recent smartphone, a card reader, or a minimal understanding of authentication applications. For these groups, “easy” access to online health information remains theoretical.
Mutual insurance companies and certain patient associations offer support, but these initiatives vary by region. The issue is no longer just technical: it falls under a structured public policy.
European Health Data Space: What Changes from 2027
The regulation (EU) 2025/327, adopted on March 26, 2025, creates the European Health Data Space (EHDS). The first obligations will gradually apply from March 26, 2027, and then from March 26, 2029, for much of the secondary use of data.
For Belgian patients, this European framework ultimately implies cross-border access to their health data. A Belgian hospitalized in another member country could have their history accessed by the local doctor through the MyHealth@EU platform. Conversely, medical data from a stay abroad could be returned to the Belgian file.
Uncertainties About Implementation
The announced timelines are ambitious. Interoperability between national systems requires each state to adapt its infrastructures, encoding standards, and consent procedures. The available data do not allow for a conclusion that Belgium, with its regionalized architecture, will be ready within the expected timelines.
Cybersecurity is another issue. The increase in cyberattacks against healthcare facilities in Belgium and Europe turns data protection into a condition of access. A vulnerable system can be temporarily taken offline, depriving patients of access to their own information.
Number 1733 and Additional Resources for Guidance
Beyond digital platforms, the number 1733 remains the reference for non-urgent medical assistance outside office hours. It allows you to be directed to a general practitioner on duty or a pharmacy on duty in the evening, on weekends, and on public holidays.
The “Health from A to Z” page on MaSanté offers a list of reliable external websites: patient associations (Ligue des Usagers des Services de Santé, Vlaams Patiënten Platform), regional networks, helplines. These resources complement access to medical data with broader information on patient rights and support structures.
Access to online health information in Belgium is progressing, but it still relies on each citizen’s ability to navigate between multiple platforms. As long as the encoding and sharing of data remain partially voluntary, the completeness of the digital file will depend as much on the practices of caregivers as on the tools made available.
