Methods: This is a prospective cohort of patients with TBI in a tertiary trauma reference center in Brazil. Predictive values of the GCS, GCS-P, and MS-P were evaluated and compared for 14 day and in-hospital mortality outcomes and length of hospital stay (LHS). Results: The study enrolled 447 patients. MS-P demonstrated better discriminative ability than GCS to predict mortality (AUC 0.736 × 0.658; P P = 0.073). For hospital mortality, MS-P demonstrated better discrimination than GCS (AUC, 0.750 × 0.682; P P = 0.027). Both scores were good predictors of LHS (r2 = 0.084 [GCS-P] × 0.079 [GCS] × 0.072 [MS-P]). Conclusion: The predictive value of the GCS, GCS-P, and MS-P scales was demonstrated, thus contributing to its external validation in low- to middle-income country.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/47f6d18a-4a91-4269-9861-91739d195c0c/featured/hero-1781560778937.png","publishDate":"2022-11-04T00:00:00.000Z","doi":"10.25259/SNI_737_2022","categories":["Trauma","Original Article"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2022/11/11975/SNI-13-510.pdf"}
