Clinical Safety

Clinical Safety

The Open Nursing Core IG incorporates "Safety Gate" profiles designed to detect deterioration and risk.

Early Warning Scores (NEWS2)

The National Early Warning Score 2 (NEWS2) is standard in the NHS for detecting deterioration.

• Usage: MUST be calculated for all acute admissions.
• Escalation: Scores of 5+ or 3 in a single parameter require urgent clinical review.

Pressure Ulcer Risk

Braden Scale

The Braden Scale assesses risk based on sensory perception, moisture, activity, mobility, nutrition, and friction/shear.

Waterlow Score

The Waterlow Score is an alternative risk assessment tool widely used in the UK.

Automation & Safety

Systems implementing this IG SHOULD automatically trigger alerts when safety scores breach critical thresholds (e.g., NEWS2 > 5).
