A new prognostic model developed at Huashan Hospital affiliated to Fudan University offers hope for improving outcomes for patients suffering from traumatic intracranial hemorrhage (tICH). By using data from 245 individuals diagnosed with tICH who underwent surgical evacuation, researchers created and validated a nomogram to assist medical professionals in predicting patient mortality risk.
The study, which spans nearly two decades from August 2005 to August 2023, reveals the sobering reality of tICH-related mortalities, particularly highlighting the approximately 11.42% overall mortality rate among patients studied, which escalates to 28.13% for those aged 65 and older. With approximately 50% of traumatic brain injury (TBI) cases presenting as intracranial hemorrhages, this area remains critically important for clinical intervention.
The team utilized LASSO regression and Cox regression analysis methodologies to develop the nomogram, which incorporated significant variables including age, Glasgow Coma Scale-Motor scores, history of hypertension, and the presence of cerebellar hematoma. “The nomogram showed good calibration and discrimination, with a 1-year C-index of 0.882 and 0.818 for the primary and validation cohorts, respectively,” said the authors of the article.
Notably, the decision curve analysis revealed the nomogram’s practical clinical value, showcasing its utility at threshold probabilities ranging between 10% and 100%. This could empower neurosurgeons and other healthcare providers to make more informed decisions based on the model’s outcomes, potentially changing the course of treatment for at-risk patients.
Traumatic brain injury remains one of the leading causes of disability and death globally, affecting millions annually. Understanding the predictors of adverse outcomes, as outlined by the study, is increasingly pressing amid rising incidences of falls, traffic accidents, and other trauma-related events.
Prior predictive models existed, yet they often lacked specificity or comprehensive applicability. This new nomogram, focusing solely on surgical cases, is seen as a significant step forward. The research team believes future efforts could involve external validations to refine the model's applicability across different demographic groups and clinical settings.
Overall, the development of this predictive nomogram could revolutionize how clinicians assess risk and tailor treatment plans for patients with tICH. Its successful implementation might lead to not only improved survival rates but also enhanced communication between clinicians and patients, ensuring all parties are informed about prognosis and possible outcomes.
Moving forward, continued research and validation studies will be key to establishing the nomogram's status as a standard tool within clinical practice, potentially setting new benchmarks for safety and efficacy on the emergency and neurosurgical front.
