Burn wound colonization can progress to invasive infection. During 14 years of this study, the burn center was relocated to a center with improved infrastructure. This study investigates the association that infrastructure, geography and time may have on colonization. Data were collected Oct-2004 to Aug-2018, relocation took place June-2010, defining the two study periods. Admission swabs were within 48 hours. Unique isolates and resistance data were analyzed and compared statistically between two study periods. 2,001 patients with 24,226 wound swabs were included. Median age 45.4 [IQR30.2-61.6], length of stay 11 days [IQR6-21] and %TBSA 5.5 [IQR2.5-11]. Staph. aureus (33.7/100 patients) and Pseudomonas spp. (13.1/100 patients) were the most prevalent bacterial growths. After admission, prevalence of MRSA, coliform spp. and Aci. baumanni were greater in first site, candida spp. colonization was higher in the second study period site. Prevalence of patients affected by multi-drug resistant organisms was lower in the second study site, 13.5/100 patients vs 16.6/100 patients, p<0.05. There are differences in burn wound colonization across time, within the same region. Candidal spp. growth has been shown to be increased over time and represents an added challenge. Awareness facilitates effective empirical antimicrobial therapies and protocols locally.
