Observations, NEWS2 and local deterioration tools

Observation tools help staff describe deterioration clearly. They do not replace clinical judgement. If a resident looks seriously unwell, is deteriorating rapidly or has red flags, call for urgent help without waiting to complete every box on a form.

Observations that may matter

• Temperature: high, low or normal in context; a normal temperature does not rule out sepsis.
• Respiratory rate: fast breathing is an early and important warning sign.
• Oxygen saturation: useful if equipment is available and staff are trained, but do not delay urgent assessment to measure it.
• Pulse or heart rate: fast, irregular or markedly different from a resident's usual rate may be significant.
• Blood pressure: low or much lower than usual is concerning when measured.
• Consciousness and mental state: new confusion, drowsiness, agitation or reduced responsiveness is significant.
• Urine output: not passing urine, dry pads or low catheter output can indicate deterioration.
• Skin and circulation: mottled, ashen, clammy, blue, grey or pale skin, rash or cold peripheries are relevant signs.

NICE recommends using NEWS2 in acute hospital, acute mental health and ambulance settings for people aged 16 or over with suspected sepsis. In community settings, including care homes, NICE advises considering an early warning score. Many care homes use local tools such as RESTORE2 or RESTORE2 mini, which combine observations with soft signs and escalation prompts.

Management controls

Tools help you describe risk. They should speed up escalation, not slow it down.
