AANS Online Scientific Sessions: Trauma-An External Validation of the Surviving Penetrating Injury to the Brain (SPIN) Score

Video Transcription

Video Summary

In this video, Mark Johnson, a neurosurgery resident at the University of Cincinnati, presents their work on validating the Surviving Penetrating Injury to the Brain (SPIN) score. The SPIN score, developed in 2016, is a model that uses clinical variables to estimate mortality following cranial gunshot wounds. The components of the SPIN score include motor GCS, pupillary function, self-inflicted injury motive, transfer status, gender, injury severity score, and initial INR. The model demonstrated excellent discrimination, with motor GCS and pupillary function being the dominant predictors of mortality. The SPIN score was validated in a multicenter series of 257 patients, showing good model discrimination. The score was further validated in their institutional dataset and found to be a sufficient predictor of inpatient mortality. The continuous motor GCS alone performed similarly to the full SPIN model. The study suggests that the continuous motor GCS may be a reliable predictor, reducing bias due to missing data. The findings were also validated for six-month mortality. The speaker acknowledges the employees of the UC Medical Center Trauma Registry and Center for Clinical and Translational Sciences, as well as the members of the Crane Collaborative for their support.
