Evaluating risk level

NICE has produced visual summaries on evaluating risk of severe illness of death from sepsis in:

1.5 Grading risk

People have the right to be involved in discussions and make informed decisions about their care, as described in NICE's information on making decisions about your care.

Making decisions using NICE guidelines explains how we use words to show the strength (or certainty) of our recommendations, and has information about prescribing medicines (including off-label use), professional guidelines, standards and laws (including on consent and mental capacity), and safeguarding.

1.5.2

Recognise that people under 16 with suspected sepsis are at high risk of severe illness or death from sepsis if they meet any of the high risk criteria:

  • For children under 5, see high risk criteria in table 1.

  • For children aged 5 to 11, see high risk criteria in table 2.

  • For young people aged 12 to 15, see high risk criteria in table 3. [2016]

1.5.3

Recognise that people under 16 with suspected sepsis are at moderate to high risk of severe illness or death from sepsis if they meet any of the moderate to high risk criteria:

  • For children under 5, see moderate to high risk criteria in table 1.

  • For children aged 5 to 11, see moderate to high risk criteria in table 2.

  • For young people aged 12 to 15, see moderate to high risk criteria in table 3. [2016]

1.5.4

If people under 16 with suspected sepsis do not meet any high or moderate to high risk criteria, see them as being at low risk of severe illness or death from sepsis. [2016]
