An ELEMENT to represent a derived Kt/V observation.
Kt/V is a measure of haemodialysis adequacy.
Kt/V can be predicted from one of several simple formulae requiring as input data the pre- and post-dialysis urea concentrations,
the duration of dialysis, and the weight loss during dialysis. Kt/V can be calculated using several formulae giving different
results and hence, if Kt/V is being used for comparative audit, it is important that the raw data are collected to allow calculation
of URR and
estimated Kt/V using a single formula.
The result of a Kt/V calculation may be inclusive of the subject of care's residual kidney function.

1..1 |
The globally-unique identifier by which this node in the EHR hierarchy is referenced in the EHR system to which the data were
first committed. This identifier shall be retained by the EHR Recipient and re-used whenever this RECORD_COMPONENT is subsequently
included in another EHR_EXTRACT.
