Risk Factors of Tseng et al for Predicting Colonization with Multidrug-Resistant (MDR) Gram-Negative Bacteria of a Patient Being Admitted to the Hospital
Tseng et al identified risk factors for a patient being colonized with a multidrug-resistant (MDR) Gram negative bacteria. The authors are from the National Taiwan University.
Patient selection: being admitted to the hospital
Outcome: presence of a Gram-negtive bacteria that is resistant to >= 3 antibiotics in a surveillance of early clinical culture (collected <= 48 hours from admission)
Parameters
(1) age in years
(2) residence in a long-term facility
(3) history of cerebrovascular accident
(4) hospitalization within the past month
(5) recent antibiotic exposure

total score =
= SUM(points for all 5 parameters)
Interpretation:
• minimum score: 0
• maximum score: 10
• The higher the score the greater the risk of being colonized.
• A score >= 4 is associated with a high risk of being colonized and developing a MDR Gram negative infection during the hospitalization.
