Background Infection is a leading cause of morbidity and mortality in the ventricular assist device (VAD) population. We performed a retrospective cohort study outlining the epidemiology of multidrug-resistant organism (MDRO) colonization and infection rates in this population. Methods We performed a longitudinal retrospective cohort of all patients receiving continuous-flow (axial and centrifugal) ventricular assist devices from July 2008 to September 2018 at Northwestern Memorial Hospital. Peri-operative prophylaxis from July 2008 to June 2013 was vancomycin, rifampin, ciprofloxacin, and fluconazole, and vancomycin plus cefuroxime from June 2013 to September 2018. VAD-specific and VAD-related Infections were classified according to ISHLT 2013 definitions. Patients were screened for methicillin-resistant Staphylococcus aureus, vancomycin-resistant Enterococcus faecalis or Enterococcus faecium, or extended-spectrum β-lactamase producing Gram-negative rods. Statistics were performed using IBM® SPSS Statistics version 25.0. Comparative statistics were performed using two-sided Fisher’s exact test with a P-value of &lt;0.05 deemed significant. Results A total of 89 patients with ventricular assist devices developed either VAD-specific or VAD-related infections and were included in the analysis. 77% of patients (n = 66) were colonized with an MDRO; 29% (n = 25) with MRSA, 73% (n = 63) with VRE, and 24% (n = 21) with an ESBL organism. 17.9% (n = 16) of patients who went on to develop infection was secondary to MDROs. Colonization with an MDRO was associated with subsequent infection secondary to these organisms (P = 0.018). Conclusion Colonization rates of multidrug-resistant organisms in the VAD population are high. VRE rates were significantly higher than MRSA or ESBL, possible as a result of peri-implantation utilization of vancomycin as surgical site prophylaxis. MDRO colonization was associated with progression to VAD-specific or VAD-related Infection. Disclosures All authors: No reported disclosures.
