Surgical Management of Diabetic Foot Burns Is Associated With Poor Outcomes: A Systematic Review and Meta-Analysis.

There is no consensus on the optimal management of diabetic foot burn injuries. Here, we systematically identify studies reporting on diabetic foot burns and evaluate outcomes among patients managed operatively vs nonoperatively. PubMed, Embase, and Web of Science were searched. Screening was performed by independent reviewers. Primary research studies with English full texts published between 1980 and 2023 that discussed outcomes of foot burns in adults with diabetes were included and critically appraised using validated tools. Results are presented using descriptive statistics of aggregated data. The search yielded 2402 nonduplicate papers, of which 35 met the inclusion criteria. Nine papers were included for meta-analysis, including 7 retrospective comparative analyses, 1 cross-sectional study, and 1 retrospective chart review. There were 1798 diabetic foot burn patients. The mean age was 58.2 years (SD 4.12), and 73.1% (n = 1314) were male. A total of 15.7% (n = 283) of patients were surgically managed, including debridement (3.7%, n = 66), grafting (8.2%, n = 147), flap (0.2%, n = 3), and primary amputation (7.1%, n = 127). The secondary amputation rate, defined as amputation following initial surgery, was 4.9% (n = 14). The overall amputation rate was 7.8% (n = 141). Other complications included infection (4.0%, n = 72), osteomyelitis (1.9%, n = 34), and graft failure (8.2%, n = 12). One study reported functional status at the last visit. Diabetic foot burns are highly morbid. The surgical management of these complex injuries is high risk, as amputation results in poorer quality of life and functional outcomes.
