No, although the National Exchange Point is a nationwide network, it operates regionally. Regional partitions have been put in place so healthcare providers can only exchange data within their region. There are 44 regions in total. Healthcare providers located on the border of multiple regions can request to be classified for multiple regions. Hospitals are an exception. For patient safety, they can request data from care providers in various regions, because they regularly provide care to patients from other regions or even nationwide. And in some cases they may request information from all over the country.
Your GP and pharmacist may share your medical information with other healthcare practitioners after your permission. You can ask them whether they have processed your permission and made your data available to other healthcare providers through the National Exchange Point. You can also see a tracking overview in your Personal Portal. With this overview you can see which healthcare providers have made your medical data available.
No. No medical data is stored in the National Exchange Point. That data stays in the computer systems of your GP and pharmacies. The National Exchange Point only contains a reference index with Civic Service Numbers (BSNs). Based on your BSN, your healthcare provider can search through this reference index and see which other healthcare providers have provided medical information about you.
