Definition:

The National Institutes of Health (NIH) defines a CDE: as “a data element that is common to multiple data sets across different studies.” (http://www.nlm.nih.gov/cde) or fundamental logical units of data pertaining to one kind of information1

Example:

Blood Pressure: to measure and report on Blood pressure (BP), the CDE could be captured and reported a systolic BP value and diastolic BP value using the measurement unit= mmHg. Further method specification, such as “Using sphygmomanometer (correct cuff size) and right upper arm, after sitting quietly for 5 minutes, cuff pressure inflated 30 mmHg above the palpated SBP and deflated 2 mmHg per second” would help assure that data reported from multiple studies were assessed and reported in a consistent way.
