Profile: cqf-observation-absent

The official URL for this profile is: 

http://hl7.org/fhir/Profile/cqf-observation-absent-cqf-observation-absent

. Profile of Observation Absent for decision support/quality metrics. Describes an observation that was not made, and records the reason that the observation is absent. An absent observation does not have a value, but does have identifying attributes and an absent reason. Removes modifying attributes and specifies which elements must be supported (understood) by CQF-compliant systems. : Clinical Quality Framework (CQF) Observation Absent Profile

This profile was published on Mon, Nov 10, 2014 00:00+1100 as a draft by Health Level Seven, Inc. - CQI WG.
