The representation of age group ranges code should be unambiguous, human readable and machine-readable. There being no commonly available coding system or convention for expressing or representing age ranges for aggregate data exchange, ADX expresses an age group band through two simple durations as defined in the ISO 8601. The definition below provides the grammar for a coding system. The URL for this Coding System is http://profiles.ihe.net/fhir/CodeSystem/IHE_ADX_agerange (for use in HL7® FHIR®), and the OID is 1.3.6.1.4.1.19376.1.7.3.1.1.29.1 (for use in HL7® CDA® and Version 3 standards).

ADX describes an age group range as two durations: &ltduration1&gt – &ltduration2&gt. Where duration1 specifies the beginning of the age group band (everyone who is this age and above) and duration2 signify the upper bound of the age group band. Therefore, age groups like ‘1-9 years’ means everyone who is at least one year old and less than 10 years old represented as P1Y–P10Y,age group like ‘10-14 years’ means everyone who is at least 10 years old and less than 15 years old is represented as P10Y–P15Y.

Durations define the amount if an intervening time between two time points. These durations are represented in the form P[n]Y[n]M[n]DT[n]H[n]M[n]S or P[n]W. The [n] is replaced by the value for each of the time elements that follow the [n] and the letters have the meaning:

  • P is the duration designator (for period) placed at the start of the duration representation.
  • Y is the year designator that follows the value for the number of years.
  • M is the month designator that follows the value for the number of months.
  • W is the week designator that follows the value for the number of weeks.
  • D is the day designator that follows the value for the number of days.
  • T is the time designator that precedes the time components of the representation.
  • H is the hour designator that follows the value for the number of hours.
  • M is the minute designator that follows the value for the number of minutes.
  • S is the second designator that follows the value for the number of seconds.
