Limitation of life-sustaining treatment in severe trauma in the elderly after admission to an intensive care unit.

OBJECTIVE

To analyze the factors associated to limitation of life-sustaining treatment (LLST) measures in elderly patients admitted to an intensive care unit (ICU) due to trauma.

DESIGN

A retrospective, descriptive, observational study was carried out.

SETTING

ICU.

PATIENTS

A total of 149 patients aged 65 years or older admitted to the ICU due to trauma. Hospital mortality, the decision to limit life-sustaining treatment and the factors associated to these measures were analyzed.

INTERVENTIONS

None.

RESULTS

The mean patient age was 76.3±6.36 years. The average APACHE II and ISS scores were 15.9±7.4 and 19.6±11.4 points, respectively. LLST were used in 37 patients (24.8%). Factors associated to the use of these measures were patient age (OR 1.16; 95% CI 1.08 to 1.25], APACHE II score (OR 1.11; 95% CI 1.05-1.67), ISS score (OR 1.03; 95% CI 1.01 to 1.06), admission due to neurological impairment (OR 19.17; 95% CI 2.33 to 157.83) and traumatic brain injury (OR 2.89; 95% CI 1.05 to 7.96).

CONCLUSIONS

LLST is frequently established in elderly patients admitted to the ICU due to trauma, and is associated to hospital mortality. Factors associated with the use of these measures are patient age, higher APACHE II and ISS scores, admission due to neurological impairment, and the presence of head injuries.
