N2 - The aim of this study was to assess whether systemic inflammatory response syndrome (SIRS) is correlated with outcomes in diabetic foot infections (DFIs). We retrospectively reviewed 137 diabetic patients admitted to the hospital with Infectious Diseases Society of America moderate and severe DFIs. We used SIRS criteria to define severe infection based on the presence of at least 2 of the following: heart rate >90 bpm, temperature >38°C or <36°C, respiratory rate >20 breaths per minute, and white blood cell count >12,000/mm3 or <4,000/mm3. Patients with severe DFI were significantly younger (median 49.6 versus 53.6 years, p = .04), less often had type 2 diabetes (88.6% versus 98.9%, p = .01), and less often had a history of previous amputation (15.9% versus 40.9%, p < .01). There were no differences in patients with severe infections defined by SIRS versus moderate infections in the need for surgery (47.7% versus 59.1%, p = .27), any amputation (20.5% versus 29.0%, p = .29), leg amputations (6.8% versus 7.5%, p = .88), duration of antibiotics (median ± standard deviation 34.1 ± 46.5 versus 31.9 ± 47.2 days, p = .47), or healing within 1 year (68.2% versus 66.7%, p = 1.00). Length of hospital stay was the only outcome variable that was significantly different in severe infections (median 12.7 ± 11.9 versus 7.8 ± 5.8 days, p = .02). Foot-related readmission was more common in moderate infections (46.2% versus 25.0%, p = .02). In conclusion, SIRS criteria for severe infections in diabetic patients with skin and soft tissue infections were not associated with a difference in outcomes other than longer hospital stay.
