Risk Factors of Falcone et al for Healthcare-Associated Bloodstream Infection in a Patient with Clostridium difficile Infection (CDI)

 

Patient selection: Clostridium difficile disease

 

Outcome: healthcare-associated bloodstream infection (BSI)

 

Pathogens isolated on blood culture:

(1) Candida species

(2) Entererobacteriaceae

(3) Enterococcus

(4) mixed isolates

 

Risk factors for healthcare-associated bloodstream infection from multivariate analysis:

(1) PCR ribotype 027 (strain of Clostridium diffiicile)

(2) recurrent Clostridium difficile infection

(3) severe Clostridium difficile infection

(4) oral vancomycin dose > 500 mg per day

 

where:

• Severe CDI was defined as a white blood cell count > 15,000 per µL OR serum creatinine more than 1.5 times the premorbid concentration.

 

The mortality rate in patients with bloodstream infection was high.
