Skin surface temperature: a possible new outcome measure for skin and soft tissue infection.

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.
