Limited impact of selective susceptibility reporting of Escherichia coli and Klebsiella isolates from concurrent blood and urine cultures

De-escalation was observed in nearly 90% of patients in both pre- and postintervention groups, and median times to de-escalation were similar in both cohorts. Because this was a retrospective study focusing on monomicrobial bacteremia secondary to a urinary source, providers may have felt more comfortable in quickly de-escalating, especially after urine culture results were available. [...]the overall sample size was small, due to a specific patient population that was included. [...]providers were allowed to contact the clinical microbiology laboratory for release of suppressed antibiotic results.
