Study design: Retrospective cohort studyObjectives: To identify independent risk factors associated with community-associated multidrug-resistant Psedomonas aeruginosa (MDRPA) in a population of veterans with spinal cord injury and disorders (SCI/D).Setting: A total of 127 Veterans Affairs healthcare facilities.Methods: Laboratory results from 1 January 2012 to 31 December 2013 were collected, and MDRPA cultures were compared with non-MDRPA cultures.Results: One thousand four hundred forty-one cultures were collected from Veterans with SCI/D, including 227 cultures with MDRPA isolates. Characteristics associated with an increased odds of MDRPA include age 50-64 (adjusted odds ratio (aOR)=1.80, 95% confidence interval (CI)=1.13-2.87), MDRPA culture in the past 365 days (aOR=9.12, 95% CI=5.88-14.15) and carbapenem exposure in the past 90 days (aOR=2.56, 95% CI=1.35-4.87). In contrast, paraplegia was associated with a 53% decreased odds of MDRPA compared with those with tetraplegia (aOR=0.47, 95% CI=0.32-0.69).Conclusions: Risk factors for community-associated MDRPA include prior history of MDRPA and exposure to carbapenems. Awareness of these factors is important for targeted prevention and treatment of MDRPA in patients with SCI/D.
