Abstract:

Objective

To investigate the epidemiological characteristics of elderly critical trauma patients in a single center to provide a reference for clinical treatment.

Methods

The clinical data of 143 elderly patients (age 65 years or older) admitted to Daping Hospital from January 2017 to June 2018 were collected. The patient's gender, age, mechanism of injury, injury severity score (ISS), pre-existing medical conditions, and hospital length of stay were analyzed. The Mann-Whitney test was utilized to compare the differences in ISS score, APACHE Ⅱ score, ICU time, and hospital stay between different injury mechanisms and ages. The Pearson χ2 test was used to compare age stratification, underlying disease classification, and number of cases with condition improvement and discharge between different injury mechanisms and ages. Logistic regression analysis was utilized to analyze the risk factors for complications.

Results

There were 71 male cases (49.65%, 71/143) and 72 females (50.34%, 72/143). The patients ranged in age from 65 to 99 years, with a mean age of (78±1) years. Of all cases, 43 (30.07%, 43/143) had multiple injuries and 100 (69.93%, 100/143) had single-site injuries. Tumble injuries were the first cause of injury (62.94%, 90/143), followed by traffic accidental injuries (27.97%, 40/143). Compared with non-tumble injuries, the ISS [9 (9, 9) vs 22 (16, 27), Z=7.574, P<0.001] and APACHE Ⅱ scores [15 (14, 17) vs 17 (15, 21), P=0.001] of tumble injuries were significantly lower, but the ICU time [2(1, 3) d vs 8 (1, 16) d, Z=4.407, P<0.001] and hospital stay [16 (12, 22.25) d vs 30 (19, 49) d, Z=4.779, P<0.001] were significantly shorter, although there was no significant difference in the rate of improvement and discharge (P>0.05). Patients with an age of 80 or older had a higher APACHE Ⅱ score [16 (15, 20) vs 14 (15, 18), Z=2.093, P=0.036)] and longer stay in the ICU [3 (1, 10) d vs 1 (1, 7.5) d, Z=2.013, P=0.044]. Regression analysis showed that APACHE Ⅱ score was a risk factor associated with complications (OR=1.771, P=0.01).

Conclusions

The main reason for elderly trauma patients to stay in the ICU is tumble injuries, followed by traffic accident injuries. In addition to age, patients with a high APACHE II score have longer ICU stays and a higher complication rate.
