Example
- Unwell-appearing
- No
- Age <= 21 days
- No
- Abnormal urinalysis / leukocyturia
- Yes
- Procalcitonin >= 0.5 ng/mL
- No
- CRP > 20 mg/L or ANC > 10 x10^9/L
- No
Result: Step-by-Step: HIGH risk per Gomez 2016 (abnormal urinalysis (leukocyturia)).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- low
- Low risk per Gomez 2016 (all preceding steps negative).
- intermediate
- Intermediate risk per Gomez 2016 (CRP >20 mg/L or ANC >10 x10^9/L).
- high
- High risk per Gomez 2016 (unwell appearance OR age <=21 d OR abnormal UA OR PCT >=0.5).
What you enter
- Unwell-appearing (step 1)
- Age <= 21 days (step 2)
- Abnormal urinalysis / leukocyturia (step 3)
- Procalcitonin >= 0.5 ng/mL (step 4)
- CRP > 20 mg/L or ANC > 10 x10^9/L (step 5)
