Craniocervical trauma above the age of 90: are current prognostic scores sufficient?

Abstract

Clinical data following head or spine trauma in patients over 90years is rare. The aim of this study was to analyze this patient cohort, assessing clinical characteristics, outcomes, and survival rates and to identify variables that may predict early mortality. A retrospective analysis of all patients over the age of 90 that were treated between January 2006 and December 2016 at our department was performed. Patient characteristics, type of injury, and comorbidities were analyzed with regard to the 30-day mortality rate as the primary outcome. One hundred seventy-nine patients were identified. Mean age was 93 (range 90-102); 105 (59%) patients were female. One hundred thirty-two (74%) and 34 (19%) of patients presented with head and spinal trauma, respectively. Fourteen patients (8%) had a combined head and spine injury. One hundred (56%) patients were treated operatively. Mean Charlson comorbidity index was 4.1 (range 0-18), mean diagnosis count was 6.2 (range 0-12), mean geriatric index of comorbidity (GIC) was 3.3 (range 1-4), and mean Barthel index was 28 (range 0-100). The 30-day mortality rate was 31%. Multivariate cox regression analysis showed that head trauma had a 1.66 hazard ratio (p = 0.036) of dying within 30days of admission, whereas a higher Glasgow coma score and surgical treatment had a hazard ratio of 0.88 (p = 0.0001) and 0.72 (p = 0.05) to reach the primary outcome. None of the standard geriatric scores reached any significant correlation with the primary outcome. Standard geriatric prognostic scores seem less reliable to predict mortality for patients above the age of 90. Higher Glasgow coma score and surgical treatment were associated with a higher survival probability.
