Early identification of the high risk patient using the estimated injury severity score and age

Abstract: A prospective study was undertaken over a 2 1/2 year period (July 1, 1985 to December 31, 1987) to determine the value of a prospective anatomical severity score ("estimated" injury severity score (EISS)), in combination with age, for early risk assessment. Five hundred ninety-two blunt trauma patients were used to develop a predictive model of mortality through a logistic regression. The model was validated using 216 patients; a high degree of agreement (Kappa 0.73) was found. When isolated head injuries were removed from the model and validation groups, the Kappa increased to 0.80. Prospective anatomical scoring in combination with age may help to identify the high risk trauma patient early during their care.

Observer error in the characterization of hepatic lesions in patients with neoplastic liver disease

Abstract: Sixteen patients with known neoplastic liver disease underwent 20 ultrasound examinations by two separate teams to determine the level of agreement in the measurement of lesion size and sonographic characteristics The intraclass correlation coefficient for the observations on lesion size was r = 097 (95% lower confidence limit r = 096) We conclude that sonographic estimation of the size of neoplastic liver lesions in highly reproducible and that the measurements obtained may be safely incorporated into the criteria of response for cancer clinical trials
