Abstract
This study aimed to determine the most accurate microbiological test for the detection of micro-organisms in infected diabetic foot ulcerations in people living with type-2 Diabetes. For 20 eligible patients, a superficial tissue swab and a deep tissue sample were taken during a regular appointment at a Diabetes out-patient's Podiatry Clinic. Two specimens were collected from each wound for microbial culturing after debridement. Infected foot ulcerations were graded according to the Wagner's classification as per clinical protocol. This study found a significant difference [p = 0.028] between the two different samples. The deep tissue sample was found to be more accurate in identifying micro-organisms than the superficial swabs, although the latter is more widely used in clinical practice. Further studies are warranted to provide more evidence to clinicians on the best method to adopt when swabbing different types of diabetic foot ulcerations with different wound classification since, it is clearly still a matter of debate how to detect wound infection.
