For good and efficient care, it is important that information is recorded and shared in an unambiguous way. To this end, systems, agreements and preconditions must be compatible. This is also known as interoperability. Interoperability is the ability of independent, non-equal organisations, parties, units, systems or individuals to work together, communicate and exchange information on the basis of equality. Nictiz, in cooperation with RSO Netherlands, has refined and described this in an interoperability model. This is based on the European Interoperability Model.

The interoperability model helps to categorise all agreements and preconditions that must be in place to share and exchange digital data in a sustainable and responsible manner.and exchange data digitally in a sustainable and responsible manner. It was also used as the basis for the approach of the Babyconnect action programme and forms the basis of our working method.

CareCodex methodology

The general global vision is that in the future, images and data will be shared more and more through the technique of IHE-XDS. This technique is based on the storage of documents in a relatively freely chosen location (repository) and the registration of where these documents are (registry). Documents are understood to be: photos, texts, ultrasound, X-rays, films, data, etc.

The CareCodex methodology is based on this and has supplemented it with solutions to secure and translate data in such a way that implementation can be accelerated and security increased.

Existing hardware is used. The registers are located in secure networks that meet the highest standards.

Ease of use

The CareCodex concept is based on the wish that information can be found quickly, for instance in such a way that there is one screen display per care step in which all desired information is visible in a structured way. This information can come from various sources. Care providers will continue to work in the current applications to which they are already accustomed. The transition to the use of this method is therefore relatively small.

Involving the end user

An important part of the CareCodex approach is the involvement of end users. Users play an indispensable role in the whole care process and in improving or supporting it. To achieve a common approach that is supported by all parties involved, CareCodex always involves end-users in the work we do. Co-creation is necessary to make data exchange fit with practice.

Starting points

- Client is central
- Existing techniques and methods are used.
- Software suppliers are asked to make adjustments, but these are minimal and preferably avoided.

- – The application must contribute directly to the client's needs; he or she must be in control of their own data.

- Register once at the source.

- The application should minimise the need for copying data. The data is entered by the sorg provider into his own system and is then readable by another healthcare provider (according to consent). If data is already copied, it must be clear that it has been copied.
- Supporting integral cooperation.

- The application must be suitable for the Multi Disciplinary Consultation (MDO).

- Healthcare providers have and will continue to have the possibility of working in their own (current) systems.

- The application should not require the healthcare provider to work with another application. The healthcare provider is familiar with, and has confidence in, their own application.

- Solution must be sustainable: comply with (IHE) international standards and with laws and regulations.g.
