info

Recognise

Suspect CRBSI in any patient with central venous catheter / port / haemodialysis catheter + fever / sepsis without other source. Local signs (purulence, erythema) absent in many. • Take paired blood cultures: peripheral + each line lumen, BEFORE antibiotics, with simultaneous timing labelled. • Differential time to positivity: line ≥2h before peripheral suggests CRBSI. • Quantitative cultures or paired (line:peripheral) ratio ≥3:1 also diagnostic.
