Data Standards Programme

The Acute Myocardial Infarction Data Set papers presented to the last Information Standards Board (ISB) meeting in December 2002, included references to two different version numbers. This was noted by ISB and the data set project has now standardised the version number to Version 5.

DSCN 52/2002 referenced Acute Myocardial Infarction Core Data Set Version 3.0. It is proposed in this paper to remove the version number from all the references in the dictionary, so that as the version changes updates will not be required to the dictionary text.
