For Gram-negative bacteremias, 7 days of antibiotics is enough


 

REPORTING FROM ECCMID 2018

The European Union and Infectious Diseases Society of America and the Society for Healthcare Epidemiology of America have all recently updated their antibiotic stewardship guidelines to include a strong recommendation for the shortest effective duration of antimicrobial therapy.

However, most of the supporting data were drawn from randomized, controlled studies of patients with lung, skin, and kidney infections. Short-course treatments have not been adequately studied in bacteremia patients, Dr. Yahav said.

The aim of her study, which was investigator initiated and received no external funding, was to demonstrate the noninferiority of 7 days of antibiotic therapy, compared with 14 days, in patients with bacteremia arising from Gram-negative infections.

The randomized, open-label study comprised 604 patients in three hospitals: two in Israel and one in Italy. Patients were eligible if they had an aerobic Gram-negative bacteremia of any infection source that was either community- or hospital acquired. The medication choice was left up to the treating physician. Patients were assessed at discharge, and at days 30 and 90.
