Association of 30-Day Mortality With Oral Step-Down vs Continued Intravenous Therapy in Patients Hospitalized With Enterobacteriaceae Bacteremia.

Importance: Conversion to oral therapy for Enterobacteriaceae bacteremia has the potential to improve the quality of life of patients by improving mobility, eliminating catheter-associated discomfort, decreasing the risk for noninfectious and infectious catheter-associated adverse events, and decreasing health care costs.

Objective: To compare the association of 30-day mortality with early oral step-down therapy vs continued parenteral therapy for the treatment of Enterobacteriaceae bloodstream infections.

Design, Setting, And Participants: This retrospective multicenter cohort study included a 1:1 propensity score-matched cohort of 4967 unique patients hospitalized with monomicrobial Enterobacteriaceae bloodstream infection at 3 academic medical centers from January 1, 2008, through December 31, 2014.

Comparing the Outcomes of Adults With Enterobacteriaceae Bacteremia Receiving Short-Course Versus Prolonged-Course Antibiotic Therapy in a Multicenter, Propensity Score-Matched Cohort.

Background: The recommended duration of antibiotic treatment for Enterobacteriaceae bloodstream infections is 7-14 days. We compared the outcomes of patients receiving short-course (6-10 days) vs prolonged-course (11-16 days) antibiotic therapy for Enterobacteriaceae bacteremia.

Methods: A retrospective cohort study was conducted at 3 medical centers and included patients with monomicrobial Enterobacteriaceae bacteremia treated with in vitro active therapy in the range of 6-16 days between 2008 and 2014.

A Seven-Day Course of TMP-SMX May Be as Effective as a Seven-Day Course of Ciprofloxacin for the Treatment of Pyelonephritis.

Background: The Infectious Diseases Society of America guidelines recommend either 14 days of trimethoprim-sulfamethoxazole (TMP-SMX) or 7 days of ciprofloxacin for the treatment of pyelonephritis. Antibiotic courses of 7 days of TMP-SMX vs 7 days of ciprofloxacin for pyelonephritis have not been previously compared. We evaluated the odds of a subsequent, symptomatic urinary tract infection (UTI) for women with Escherichia coli pyelonephritis receiving a 7-day course of TMP-SMX vs a 7-day course of ciprofloxacin.
