Background
Damage control (DC) strategy has significantly contributed to mortality reduction in massively bleeding and critically injured trauma victims. However, there is a lack of literature validating the effectiveness of this approach in the elderly population.
Methods
The trauma registry of a Level I trauma center was utilized to identify all severely injured patients [Injury Severity Score (ISS) ≥16] from January 1996 to December 2007 who underwent initial DC procedures. Patients with a head Abbreviated Injury Scale (AIS) ≥3 were excluded from the analysis. Demographics, clinical and physiological parameters, and in-hospital outcome measures were compared between elderly (≥55 years) and younger (<55 years) patient cohorts subjected to DC procedures.
Results
Overall, 158 patients met the inclusion criteria. Among them, 34 patients (21.5%) were aged ≥55 years (range 55–85 years) and 124 patients (78.5%) were <55 years old (range 16–54 years). The overall in-hospital mortality rate was 10.1% (n = 16) with a significantly higher mortality rate for elderly patients than for younger patients: 29.4% vs. 4.8%; adjusted P = 0.001; adjusted odds ratio (OR) with 95% confidence interval (CI) 7.09 (2.30–21.74). When stratified by DC subgroups, the case-fatality rate was significantly higher for the elderly patients who underwent extremity DC procedures [19.2% vs. 3.2%; adjusted P = 0.032; adjusted OR with 95% CI 5.95 (1.16–30.30)] and DC laparotomy [55.6% vs. 7.1%; P = 0.005; OR and 95% CI 16.25 (2.32–114.06)]. Both cohorts required massive transfusion during the initial 24 h of admission (18.9 ± 2.9 vs. 15.1 ± 1.6 units of packed red blood cells; P = 0.290). Nevertheless, there were no statistically significant differences between the two groups regarding hospital and surgical intensive care unit lengths of stay or major in-hospital complications.
Conclusions
The mortality rate for elderly trauma patients undergoing DC is excessive at 29%. Despite the significant burden of injury and the massive transfusion requirement, most of the elderly patients subjected to DC survived and experienced in-hospital morbidity measures comparable to those of the younger patients. Our results provide further support for damage control intervention in severely injured elderly patients.
