CHOICE UTI

Clinical efficacy of single dose (daily) IV antibiotics followed by 2 days oral antibiotics compared to 3 doses (daily) IV antibiotics for children with complicated urinary tract infections: a multicentre randomised trial

UTI is the most common reason in the developed world for children to need antibiotics, accounting for 12% of preventable hospitalisations across all age groups. The most frequent reason for children with UTI requiring hospitalisation is for IV antibiotics which is a major burden for healthcare systems. For those without complicating factors, there is good evidence for treatment with oral antibiotics at home. For children with complications such as vomiting and urological abnormalities, there is little evidence for route of antibiotic treatment or treatment duration because previous trials have excluded this cohort. This trial aims to investigate whether single dose of parenteral antibiotics followed by 2 days oral antibiotics is non-inferior to three doses for children with UTI and co-existing complicating factors presenting to the ED.

Study design

This study is an open label, multi-centre, non-inferiority randomised controlled trial (RCT). It incorporates a two-arm, non-inferiority design with parallel arms and 1:1 allocation of children presenting to the ED with a febrile complicated UTI treated with parenteral antibiotics.
