RESUMO
BACKGROUND: This study describes the novel use of skin surface temperature to measure the severity and the response to treatment of skin and soft tissue infection (SSTI). METHODS: Patients admitted with SSTI for intravenous antibiotic therapy. Skin temperature was measured daily at the point of maximum heat on the SSTI affected limb and the non-affected limb using a non-contact laser thermometer. FINDINGS: Sixty-three patients were included. Mean length of stay was 4.95 days. The difference between affected and unaffected limb was 3.5° C (95% CI 3.0-3.9) at day one and 2.1° C (95% CI 1.7-2.6) on the last day, a difference of 1.4° C (95% CI 0.7-1.9). Between day one and the last day, there was a significant reduction in affected limb temperature (mean reduction of 2.4° C, 95% CI 1.9-3.0 p<0.001). INTERPRETATION: Skin surface temperature may hold a useful role in the management of SSTI.
