[Results of resuscitation in injured elderly patients]

This study assessed the results of intensive care in elderly trauma patients and quantified the different factors involved in the final outcome. It included 116 patients, aged 65 years or more, and covered a two year period. The following parameters were obtained for each patient: age, severity of trauma (ISS and SAPS), head injury (GCS), prehospital health status (ESA), survival after three months and quality of survival. Three months after trauma, overall mortality was 45.7%. Survivors were 72.8 +/- 4.9 year old, while those that died were 75.3 +/- 7.5 year old (p = 0.01). Mean ISS was 19.7 +/- 8 and mean SAPS was 9.4 +/- 3.2. The risk of death was 3.6 (1.6 to 8.1) times greater if ISS was over 15. The same risk was 4.7 (2.1 to 11.1) times greater if SAPS was over 9. GCS was 8.8 +/- 4.4 in dead patients and 12.5 +/- 2.4 in survivors (p = 0.001). The risk of death was 10.4 (4.2 to 26.2) times greater if GCS was under 8. The final prognosis could be assessed with the following exponential model: Survival = 1/(1 + exp - (8.7 - 0.07 X age - 0.07 X ISS - 2.9 X GCS*), where GCS is equal to 0 if the real GCS was under 8, and equal to 1 otherwise. The ESA did not affect mortality. Three months after trauma, the degree of independence was the same as before in 87% of survivors. It was concluded that age and the severity of trauma were the most important factors in determining prognosis in geriatric trauma patients.(ABSTRACT TRUNCATED AT 250 WORDS)
