Porat et al reported risk factors associated with 30-day readmission following Gram-negative bacteremia. These can help to identify a patient who may benefit from more aggressive management. The authors are from Rambam Health Care Campus, Technion-Israel Institute of Technology and Rabin Medical Center in Israel.

Patient selection: hospitalization with Gram-negative bacteremia


Outcome: 30-day readmission (occurred in 20%)


Mean age: 70 years


Predictors for readmission:

(1) inappropriate empirical antibiotic therapy during the first 24 hours of bacteremia

(2) cephalosporin-resistant bacteria

(3) higher predischarge heart rate (HR 1.3 per 10 bpm increment)

(4) low serum albumin

(5) active malignancy

(6) long-term nasogastric tube

(7) immunosuppression

(8) anticoagulation or antiplatelet drugs at home

(9) anxiolytics or hypnotics at home

(10) Arab ethnicity


The hazard ratios were from 1.2 to 1.8, so multiple predictors are needed to have an impact.
