A multicenter, prospective, cross-sectional study by Nelson et al indicated that the use of tissue samples is superior to that of wound swabs in identifying pathogens in infected diabetic foot ulcers. The investigators found that pathogens were more often identified, and nonpathogens less often identified, using tissue samples than wound swabs, with antibiotic regimen changes more frequently recommended by blinded clinicians in response to the results of tissue samples than to those of swabs.
