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.

Usage:

• Examples for this Resource Profile: Observation/example-nonpatient-hemodialysis-machine, Observation/example-nonpatient-hospital-bed and Observation/example-nonpatient-mechanical-ventilator
