                        Within the domain of health and healthcare  there are a large number of data flows with various objectives operational in Belgium  administrative data flows  data flows that guarantee the continuity of care (patient-related follow-up)  or the traceability of a condition  medicine or healthcare product. There are also many data collections in the context of epidemiology and quality of care  for example. This last group of scientific data collections  the so-called registries  is characterised by a heterogeneous methodological approach  not only in terms of technology (paper  fax  email  web applications  batch upload  web services)  but also with regard to content (different data structures). Furthermore  the same data is often requested multiple times from the same data provider. The consequences of this diversity for the providers and collectors of this data include reduced efficiency in the registration and processing of the information (a lot of manual data cleaning  retyping and mapping)  real privacy risks and the scattered deployment of IT resources and people for the same tasks. Moreover  this context is not motivating for the (highly skilled) employees involved in these data collections (both among the data providers and the researchers). Finally  this situation leads to a high (direct and indirect) financial commitment on the part of data providers  the researchers and their clients. The healthdata.be team opted to align the standardization of these so-called  real world data  projects with the clinical context (in stead of starting from the research context) and to look for an information architecture that can be technically implemented in the various applications used in the Belgian healthcare landscape. One of the initiatives studied by the healthdata.be team is the “Registration at the source” project of the Dutch University Medical Centers (UMCs)  united in the Dutch Federation of University Medical Centers (NFU). Within this initiative  which is supported by the National ICT Institute in Healthcare (NICTIZ)  it was decided to work together in the field of standardization of healthcare data. The result of this collaboration is a set of so-called “Zorginformatiebouwstenen” (or Clinical Building Blocks). These Dutch Zorginformatiebouwstenen are reviewed and adapted to national landscape by the healthdata.be team and their stakeholders. The result are  Clinical Building Blocks  which are published on Simplifier as logical models. In a next step  the clinical building blocks will be translated into HL7 FHIR R4 compliant profiles and related conformance materials for data collections supported by healthdata.be (Sciensano). All assets will become available on Simplifier.
