# QICore NonPatient Observation - QI-Core Implementation Guide v8.0.0-ballot

## Resource Profile: QICore NonPatient Observation 

 
Profile of NonPatient Observation for decision support/quality metrics evaluating resource use and availability rather than focusing on patients. Defines the core set of elements and extensions for quality rule and measure authors. 

"Must Have", "QI Elements" and "primary code path" are defined in the
[QI-Core Must Support section](index.md#mustsupport-flag).

**QI Elements:**
* performer: (QI) Who is responsible for the observation
* derivedFrom: (QI) QI Core Profiles or other resource the observation is made from
* category: (QI) Classification of type of observation
* code: (QI) Type of observation (code / type)
* subject: (QI) The device/location/implantable device the observation is about
* value[x]: (QI) Actual result
* status: (QI) registered | prliminary | final | amended | corrected | cancelled | entered-in-error | unknown
* effective[x]: (QI) Clinically relevant time/time-period for observation
* interpretation: (QI) High, low, normal, etc.

**Primary code path:**code

(PCPath) This element is the primary code path for this resource
