ABSTRACT
BACKGROUND:
The revised American Association for the Surgery of Trauma (AAST) organ injury scale (OIS) for splenic injury incorporates radiologic features but the implications of this are unknown. We hypothesized that the revised AAST-OIS would better predict outcomes.METHODS:
Patients with a blunt splenic injury admitted to a Level I trauma center were reviewed from 2016 to 2021. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for splenectomy were calculated for high-grade injuries (AAST-OIS grades IV-V) using both schemas.RESULTS:
Of the 852 patients analyzed, 48.5% were observed, 24.6% were embolized, and the remaining underwent operative intervention. The median AAST-OIS increased from II to III (p â< â0.01). Sensitivity (38.0% vs. 73.7%) and NPV (80.9% vs. 88.2%) for splenectomy increased for high-grade injuries but specificity (93.5% vs 70.1%) and PPV (67.5% vs 46.7%) decreased.CONCLUSION:
The revised AAST-OIS better predicted splenic salvage but is less accurate at predicting need for splenectomy.
