Mortality and One-Year Functional Outcome in Elderly and Very Old Patients with Severe Traumatic Brain Injuries: Observed and Predicted

Table 4

Observed 14-day mortality and unfavorable outcome of 12 months and CRASH predicted 14-day mortality and 6-month outcome based on clinical (CRASH basic) and combined clinical and CT based information (CRASH CT). Results are shown for all patients ≥ 65 years, the old group (65–74 years), and the very old group (≥75 years).

	Observed	Predicted (CRASH basic)	Predicted (CRASH CT)
≥65 years ()
Mortality	50%	64 (56–71)%	81 (73–87)%
Unfavorable outcome	72%	90 (86–92)%	95 (91–96)%
65 to 74 years ()
Mortality	35%	54 (45–56)%	74 (64–81)%
Unfavorable outcome	44%	85 (80–87)%	92 (88–95)%
≥75 years ()
Mortality	63%	73 (65–80)%	88 (81–92)%
Unfavorable outcome	86%	93 (91–95)%	97 (94–98)%

Unfavorable outcome is defined as dead and GOSE score <5.
