Short-course antibiotic therapy okay for Pseudomonas bloodstream infections in febrile neutropenia

Key findings of this study are:

• Four hundred thirty-four patients met the eligibility criteria.
• The short course was 7-11 days in 229 cases, and the prolonged course was 12-21 days in 205 patients.
• Short-course antibiotic therapy had similar outcomes to the prolonged course.
• Eight patients (3.9%) in the short-course group and ten patients (4.9%) in the prolonged-course group experienced a recurrent PA infectiona at any site or mortality within 30 days of completing therapy.
• The recurrent infection within 90 days occurred in 9.8% and 6.3 % of patients in the short- and prolonged-course groups.
• Seventeen patients in the short-course group and 15 in the prolonged-course group had recurrent fever within seven days.
• Patients on short-course antibiotic therapy spent 3.3 fewer days in the hospital.

Short-course therapy was non-inferior to prolonged-course therapy in terms of clinical outcomes.

They mentioned due to limitations and bias; further investigations are warranted to generalize findings.
