Model of Ben Ayed et al for Community-Acquired Urinary Tract Infection (CUTI) Caused By a Multidrug-Resistant Enterobacteriaceae

Description

Ben Ayed et al reported a simple score for identifying a patient with a community-acquired urinary tract infection (CUTI) caused by multidrug-resistant Enterobacteriaceae. This can help to identify a patient who may benefit from more aggressive management. The authors are from Hedi Chaker University Hospital and University of Sfax in Tunisia.


Patient selection: community-acquired urinary tract infection

 

Parameters:

(1) age in years

(2) diabetes

(3) history of urinary tract surgery in the past 12 months

(4) history of antimicrobial therapy in the past 3 months

= SUM(points for all 4 parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 18

• A score >= 2 (seen if any of the risk factors is present) is associated with MDR Enterobacteriaceae.

 

Performance:

• The area under the ROC curve is 0.71.

• A score >= 2 has a sensitivity of 71% and specificity of 60%.

• A score >= 6 has a sensitivity of 43% and specificity of 85%.
