Does format change of a laboratory test order form affect physician behavior?
Changes in format of laboratory test order forms can change physician test ordering and may be useful together with other interventions to improve appropriateness of laboratory testing. A thoughtfully built test ordering form can reinforce clinical guidelines for the performance of some preventive testing and follow-up.
The significant independent predictors of survival in severely injured trauma patients are Ps, GCS score, age, mechanism of injury, and institutional volume. We found no statistically meaningful contribution to the prediction of survival on the basis of per-surgeon patient volume. Since this volume criterion for surgeon enpanelment and trauma center designation would not be expected to improve outcome, such a requirement should be justified by other measures or abandoned.
