The following information is applicable to data set specifications only. This information is displayed against the Implementation in data set specifications attribute of data elements included in the data set specifications.
The date on which the collection of data for a particular data set specification was implemented for the first time.
Conditional completion: mandatory if the data set specification is also a National Minimum Data Set (NMDS).
To specify the implementation start date, select the relevant day, month and year from the drop down lists to indicate a fully formed date (i.e., 15 February 2006).
If the data set specification does not have an implementation start date (it is not an NMDS), this attribute can be set to not applicable by ticking the checkbox to the right of the date selector.
An NMDS should be approved as a standard on a date that is before its implementation start date.
