bacteraemia, cUTI
BACTERIAL INFECTIONS, UTI
The discriminative ability increased for both Feverkidstool and the Craig model, with the strongest increases for cUTI and bacteraemia (C-statistics of 0.86 (0.83–0.86) and 0.80 (0.66–0.94), respectively). The SBI model barely improved after updating (Table Non-parametric multinomial calibration plots of updated Feverkidstool.

SBI, serious bacterial infections; RCS, restricted cubic splines; CL, confidence limitSensitivity was low for all outcome categories of the updated Feverkidstool and Craig model (< 71%). Especially for bacteraemia, the Craig model failed to correctly identify any of the cases. Specificities on the other hand were very high for all outcome categories from risk cut-offs of 10%. The sensitivity of the updated SBI model however was good at a low-risk cut-off of 2.5% risk, at the cost of a very low specificity (Table
