title: Infections in diabetic burn patients.
abstract: OBJECTIVE
  Diabetic burn patients comprise a significant population in burn centers. The purpose of the study was to determine the demographic characteristics of diabetic burn patients and their rate of community-acquired and nosocomial infections.
  
  
  METHODS
  This was a 46-month retrospective chart and patient registry review comparing diabetic with nondiabetic burn patients. Statistical analysis consisted of means +/- SD, descriptive statistics, one-way ANOVA, and chi(2) tests.
  
  
  RESULTS
  Of 1,063 adult burn patients (aged 15-54 years), 68 (6%) diabetic burns were compared with burns of 995 adult nondiabetic patients. Of 193, 62 (32%) senior (>/=55 years of age) diabetic burns were compared with 131 nondiabetic senior burns. The major mechanism of injury for the diabetic patients was scalding and contact, in contrast to that of nondiabetic patients who were injured mainly by scalding or flame burns. Adult diabetic patients had a significantly increased frequency of foot burns compared with adult nondiabetic patients (32 of 68 [68%] versus 144 of 995 [14%], P = 0.001). Adult diabetic burns had a significant increase in sepsis (P < 0.002) and community-acquired burn wound cellulitis (P < 0.001) compared with adult nondiabetic patients; and senior diabetic patients had a significantly increased frequency of urinary tract infections compared with senior nondiabetic burn patients (P < 0.04). The most common organisms in diabetic burn infections were Streptococcus, Proteus, Pseudomonas, Candida species, and MRSA (methicillin-resistant Staphylococcus aureus). Forty-two percent of the diabetic patients were admitted during the winter months and 25% in the spring. Only 49 of 130 (38%) diabetic burn patients presented for treatment within 48 h after injury compared with 669 of 1,126 (62%) nondiabetic patients (P = 0.001).
  
  
  CONCLUSIONS
  Peripheral neuropathy may have precipitated and delayed medical treatment in lower-extremity burns of diabetic patients. Hospitalized diabetic burn patients were also at an increased risk for nosocomial infections, which prolonged hospitalization. Diabetic patient education must include not only caution about potential burn mishaps but also educate concerning the complications from burns that may ensue.
