Culture of Transplant Perfusate Using BACTEC Technology and Antibiotic Prophylaxis Influences Wound Complications Within a Kidney Transplant and SPK Transplant Cohort.

Abstract Purpose Routine screening for microbial contamination in organ recovery perfusion transport solution (ORPTS) is by microbiological culture without broth enrichment. Our aim was to examine the clinical utility of broth enrichment of perfusion solution, through use of BACTEC (Becton Dickinson) blood culture media, in preventing wound complications for transplant recipients in comparison with culture without enrichment. Methods We prospectively collected samples of ORPTS of 395 kidney (n = 250) or simultaneous pancreas-kidney (SPK, n = 145) donors over a 7-year period. Results of culture with and without broth enrichment (n = 285) using BACTEC blood culture media were examined to compare the sensitivity of BACTEC with non-BACTEC methods. We then conducted a paired analysis of 110 recipients with both BACTEC and non-BACTEC culture organ perfusion media. We examined the rates of wound infection and whether the use of targeted antimicrobials reduced infections in the BACTEC group and recipients with both types of cultures. Results Of 395 patients with cultures of ORPTS, first, the results of 79 cultures performed using BACTEC media only were compared with 206 non-BACTEC cultures (n = 285). Second, 110 cultures were performed using both methods. For the first part of the study, BACTEC media detected significantly greater microbial growth than non-BACTEC methods (n = 79, 64.6% vs n = 206, 14.6%; P  Conclusions Routine screening of ORPTS with BACTEC broth enrichment should always be employed. When paired with antimicrobial prophylaxis, it has the potential to significantly reduce the risk of recipient wound infection.
