This research article reports on a randomized clinical trial (BEATLE) investigating the efficacy of extended-infusion versus intermittent-infusion β-lactam antibiotics in treating febrile neutropenia in hematological patients. The study, conducted across four Spanish hospitals, aimed to determine if extended infusion improved treatment success, defined as defervescence without antibiotic changes. Results showed no significant difference in treatment success between the two groups. However, extended infusion achieved higher pharmacokinetic/pharmacodynamic targets for susceptible Pseudomonas aeruginosa. The authors conclude that extended infusion isn't routinely warranted but may benefit patients with infections caused by less susceptible microorganisms.
