To determine whether a reference set is useful either to adopt or to build from, there is a range of parameters which can be assessed to determine whether a reference set is fit for the purpose or requirements that the developing organization have. The following diagram illustrates some of the central aspects that must be assessed when evaluating an existing reference set.

 

Exploring existing reference sets

Compare basic parameters

Firstly, the basic parameters of the existing reference set should be compared with the actual needs related to use of the new reference set. The following table provides an overview of some of the basic parameters, which should be assessed when starting to evaluate an existing reference set. Having assessed these basic parameters, it will be possible to determine whether an existing reference set is sufficient for further inspection, or whether it should be rejected as candidate source for a new reference set.

Description

Type of reference set

It should be assessed whether the functionality of the existing reference set also meet the requirements for functionality that the #developing/ seeking organization have.

The Number number of members

The numbers of members of the existing reference set should be compared to the required number of members in the new reference set.  E.g. a reference set representing a very large subset of components may be rejected if the need is a subset to capture the overall categories (body sites) of information collected during a physical examination.

Extension content included

It should be assessed whether the existing reference set is dependent on any other Edition than the International Edition. And if so, the existing reference set can only be adopted if it belongs to an Extension on which the developing/seeking organization also depends upon.

Hierarchy coverage

It should be assessed whether the components referenced in the existing reference set represents concepts within hierarchies required for the new reference set. E.g. an existing reference set should be rejected if it references concepts within the Procedure hierarchy and the new reference set is to be used for recording evaluation results, i.e. concepts/descriptions of clinical findings concepts.
