ASTM E2171-02(2008) PDF

1.1 This standard addresses the identification of data elements from the EHR definitions in Practice E 1384 that have ordinal scale value sets and which can be further defined to have scale-free measurement properties. It is applicable to data recorded for the Electronic Health Record and its paper counterparts. It is also applicable to abstracted data from the patient record that originates from these same data elements. It is applicable to identifying the location within the EHR where the observed measurements shall be stored and what is the meaning of the stored data. It does not address either the uses or the interpretations of the stored measurements.
