Artifacts Summary

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

Knowledge Artifacts: Plan Definitions

These define workflows, rules, strategies, or protocols as part of content in this implementation guide.

NEWS2 Escalation Protocol

Computable escalation protocol for NEWS2 results, encoding the RCP response bands: 0-4 routine monitoring; 3 in any single parameter registered-nurse review; 5-6 urgent review by a clinician competent in acute illness; 7+ emergency response.

Knowledge Artifacts: Libraries

These define logic, asset collections and other libraries as part of content in this implementation guide.

ONC NEWS2 Auto-Calculation Logic

Logic library for calculating National Early Warning Score 2 (NEWS2) from FHIR Observations.

Structures: Logical Models

These define data models that represent the domain covered by this implementation guide in more business-friendly terms than the underlying FHIR resources.

Relational Care Logical Model

A vendor-neutral clinical model of the relational nursing assessment. Defines WHAT data must be captured, regardless of HOW it is stored in FHIR.

Structures: Questionnaires

These define forms used by systems conforming to this implementation guide to capture or expose data to end users.

Braden Scale Capture Form

SDC questionnaire for the Braden pressure-ulcer risk assessment: six subscales, total score, and a mandatory Monk Skin Tone item (the equity fairness gate is embedded at the capture layer). Coded items extract to Observations using the ONC Braden component codes; assembling them into the single component-based ONCBradenScaleAssessment Observation (including hasMember[skinTone]) is the capturing app's responsibility.

MUST Capture Form

SDC questionnaire for the Malnutrition Universal Screening Tool: three step scores and the total. Coded items extract to Observations using the ONC MUST component codes; assembling them into the single component-based ONCMUSTScore Observation is the capturing app's responsibility.

Monk Skin Tone Capture Form

SDC questionnaire capturing the patient's skin tone on the 10-point Monk Skin Tone Scale (A–J). Extracts to an Observation conforming to ONCMonkSkinToneObservation. This record is the required input to the IG's equity fairness gate for wound and pressure-area assessment.

NEWS2 Capture Form

SDC questionnaire for capturing the NEWS2 physiological parameter set and total score. Coded items extract to Observations conforming to the ONC NEWS2 and vital-sign profiles. Scoring and escalation logic is computable via the ONC_NEWS2_Logic CQL library and the news2-escalation PlanDefinition.

Person-Centred Care Capture Form

SDC questionnaire capturing 'What Matters to Me' and reasonable adjustments (Equality Act 2010) as structured, retrievable records. Items extract to Observations conforming to ONCWhatMattersToMe and ONCReasonableAdjustment.

Waterlow Score Capture Form

SDC questionnaire for the Waterlow pressure-ulcer risk assessment total score, with a mandatory Monk Skin Tone item (equity fairness gate embedded at the capture layer). The total extracts to an Observation using the ONC Waterlow code; linking the skin-tone Observation via hasMember[skinTone] is the capturing app's responsibility.
