Why is this Important?

“Patients who are admitted to hospital believe that

they are entering a place of safety, where they,

and their families and carers, have a right to

believe that they will receive the best possible

care. They feel confident that, should their

condition deteriorate, they are in the best place for

prompt and effective treatment.

Yet there is evidence to the contrary. …………”

NICE Guidance Note Recommendations• Physiological observations in acute hospital settings (section 2.1.3)

• 1.2.2.1 Adult patients in acute hospital settings, including patients in the emergency department for whom a clinical decision to admit has been made, should have:

• • physiological observations recorded at the time of their admission or initial assessment

• • a clear written monitoring plan that specifies which physiological observations should be recorded and how often. The plan should take account of the:

– − patient’s diagnosis – − presence of comorbidities – − agreed treatment plan.

• Physiological observations should be recorded and acted upon by staff who have been trained to undertake these procedures and understand their clinical relevance.

• 1.2.2.2 As a minimum, the following physiological observations should be recorded at the initial assessment and as part of routine monitoring:

• • heart rate • • respiratory rate • • systolic blood pressure • • level of consciousness • • oxygen saturation • • temperature.
