The starting point for a consideration of data entry is an efficient method for performing text searches and
. When these functions are integrated in a terminology glossary-ref
, it is possible to select a glossary-ref
by text search and then to refine or generalize the selection to identify a more appropriate glossary-ref
A terminology glossary-ref
built into an application or offering a programmable interface can be used to allow a user to select a glossary-ref
) and enter this into a record.
This method of data entry allows unconstrained selection of any glossary-ref
. This can sometimes be useful but such an unrestricted method should only be used as a fallback, when more selective approaches cannot be used.
Limitations of simple browsers
A general-purpose glossary-ref
capable of searching and navigating through the
is a simple starting point. However, this approach is unlikely to meet the requirements for anything other than occasional entry of glossary-ref
encoded information. More selective mechanisms tailored to particular data entry contexts are likely to be more usable and may promote more consistent data recording.
In most situations in which clinical data is entered, access to the full content of glossary-ref
through a simple search and
is unlikely to be necessary and may be cumbersome and unhelpful. The main reason for this relates to the size and structure of the terminology. As a result:
- Many terms may match a single word or short phrase resulting in a long list of options;
- The depth and breadth of the glossary-ref and glossary-ref may require selection of choices from several screens to locate the required glossary-ref .
There are many ways to improve and simplify glossary-ref
data entry. Some of these can be used in a wide range of situations. Others are specific to constrained contexts that occur in structured data entry driven by a template or protocol.
