A single 8 ½" x 11" chart has been developed by condensing and editing the injury descriptions in the 1980 revision of the Abbreviated Injury Scale. To evaluate its accuracy and the ability of residents* to appropriately score patients soon after admission, 194 patients with blunt trauma admitted to a Level I Trauma Center were studied. Errors related to construction of the form occurred in 4.1% and subsequent scoring changes resulting from delayed diagnosis occurred in 5.1%. Human inaccuracy or omission, however, resulted in initial scoring errors in 25% of patients evaluated. The availability of a simple chart with the potential for early accurate injury scaling holds promise for additional usefulness of the Abbreviated Injury Scale.
