A new sepsis scale has been developed, and it consists of 13 parameters, each of which is measured daily on a variable point scale. In 41 patients with major burns the Baltimore Sepsis scale correlated well with death or survival, with occurrence of septicemia, and with the level of serum interleukin-6. It did not correlate well with the level of plasma endotoxin or with the type of organism that was grown in blood cultures (gram-positive or gram-negative). We propose that the Baltimore Sepsis Scale would be an accurate and easy scale to use for the measurement of interventions that are aimed at improving the septic state.
