## Artifacts Summary

This page provides a list of the FHIR artifacts defined as part of this implementation guide.

An important objective in the NHSN Situational Awareness Framework for Reporting (NHSN SAFR) IG is to avoid unnecessary profile proliferation and to leverage common processes. To this end the IG leverages the profiles, extensions and operations incorporated into the US Situational Awareness Framework for Reporting (US SAFR) Implementation Guide.

### Behavior: Capability Statements

The following artifacts define the specific capabilities that different types of systems are expected to have in order to comply with this implementation guide. Systems conforming to this implementation guide are expected to declare conformance to one or more of the following capability statements.

Title | Description
--- | ---
NHSN SAFR Data Aggregator CapabilityStatement | This statement defines the expected capabilities of a system that aggregates data from multiple Data Source actors before measure evaluation and then plays the role of a Data Source once aggregation is complete. An example would be a state public health agency aggregating data from all facilities in the state before using those data to produce a MeasureReport containing bed capacity data for the entire state. When FHIR enabled, a Data Aggregator acts as a US Core Server when playing the role of a Data Source after aggregation. During aggregation, the Data Aggregator acts similar to the SANER options for aggregation, but implements its own CapabilityStatement due to the incompatibilities between DEQM and SANER.
NHSN SAFR Data Evaluation Engine CapabilityStatement | This statement defines the expected capabilities of a system that retrieves data from the Data Source and evaluates those data against one or more measures retrieved from the Measure Source. The resulting MeasureReport bundle and related resources are then sent to the MeasureReport recipient. The Measure Evaluation Engine acts as a US Core Client, a DEQM Reporter Client, and implements the $evaluation-measure operation. Note: FHIR queries are not always required. In the case, an EHR retrieves data from it's own internal data store using non-FHIR methods or imports data from other systems that are not FHIR-enabled.
NHSN SAFR Data Source CapabilityStatement | This statement defines the expected capabilities of a system containing data (typically patient data, but could be situational awareness data) that will be evaluated against one or more measures. This may be a FHIR server, an EHR with a FHIR endpoint (facade), an internal data store when the Data Source and Measure Evaluation Engine actors are played by the same system such as an EHR that does it’s own measure evaluation, or it may be a system containing other data such as situational awareness data that is reporting via CSV or other format. When FHIR enabled, the Data Source acts as a US Core Server. Note: US Core Server is only needed for external evaluation engines. Examples of where this is not needed, is an EHR querying it's own data source using proprietary data access methods.
NHSN SAFR Measure Source CapabilityStatement | This statement defines the expected capabilities of a system at NHSN, federal and jurisdictional Public Health Agencies including State, Tribal, Local and Territorial (STLT) Health Departments that stores FHIR resources such as Measure, Library, ValueSet, etc. that are used for Measure Reporting. The Measure Evaluation Engine queries the Measure Source for the latest Measure content before querying the Patient Data Source and performing measure evaluation. The Measure Source acts as a CQFM Publishable Measure Repository.
NHSN SAFR MeasureReport Recipient CapabilityStatement | This statement defines the expected capabilities of a system at NHSN, federal and jurisdictional Public Health Agencies including State, Tribal, Local and Territorial (STLT) Health Departments that receives MeasureReport bundles from the Measure Evaluation Engine and validates the result against the profiles in this implementation guide, and potentially other measure-specific profiles that are distributed with the measures themselves. The MeasureReport Recipient acts as a DEQM Receiver Server, provides write access to Bundle resources containing MeasureReport and other related resources, and implements the $validate operation.
