ICT standards consolidation to overcome interoperability problems

Standards are key to interoperability because they provide the specifications which are necessary for systems to communicate meaningfully with each other. From the perspective of the buyers and users of healthcare ICT – for example general practitioners or ICT managers in hospitals, community care centres and insurance funds – interoperability problems may arise because of various shortcomings of e-health standards and standardisation.

These may include a large number of conflicting standards on the one hand but too few or insufficiently developed standards for particular solutions on the other hand. From an ICT industry perspective, there is a lack of sufficiently specified and commonly used ICT standards that meet user needs.

Consequently, a solution for the ICT interoperability challenge in the health sector may be the common use of a more confined number of well-developed and harmonised standards. This may in short be considered as “standards consolidation”. Standards consolidation is easily stated as an objective but difficult to realise. Numerous standardisation organisations, governments, and enterprises with diverging interests are struggling to maintain or gain power in defining ICT standards for the health sector. The number of standards used and the number of organisations involved in defining standards is very high and almost impossible to overview.

The complexity of the area of ICT standardisation itself is an important barrier to reach the objective of standards consolidation and even to decide where and how best to tackle it. Structuring the area of e-health standardisation and thus reducing this complexity is a key objective of standardization.
