Variation of Blunt Traumatic Injury with Age in Older Adults: Statewide Analysis 2011-14

Traumatic brain injury in elderly population: A global systematic review and meta-analysis of in-hospital mortality and risk factors among 2.22 million individuals

BACKGROUND

Traumatic brain injury (TBI) among elderly individuals poses a significant global health concern due to the increasing ageing population.

METHODS

We searched PubMed, Cochrane Library, and Embase from database inception to Feb 1, 2024. Studies performed in inpatient settings reporting in-hospital mortality of elderly people (≥60 years) with TBI and/or identifying risk factors predictive of such outcomes, were included. Data were extracted from published reports, in-hospital mortality as our main outcome was synthesized in the form of rates, and risk factors predicting in-hospital mortality was synthesized in the form of odds ratios. Subgroup analyses, meta-regression and dose-response meta-analysis were used in our analyses.

FINDINGS

We included 105 studies covering 2217,964 patients from 30 countries/regions. The overall in-hospital mortality of elderly patients with TBI was 16 % (95 % CI 15 %-17 %) from 70 studies. In-hospital mortality was 5 % (95 % CI, 3 %-7 %), 18 % (95 % CI, 12 %-24 %), 65 % (95 % CI, 59 %-70 %) for mild, moderate and severe subgroups from 10, 7, and 23 studies, respectively. A decrease in in-hospital mortality over years was observed in overall (1981-2022) and in severe (1986-2022) elderly patients with TBI. Older age 1.69 (95 % CI, 1.58-1.82, P < 0.001), male gender 1.34 (95 % CI, 1.25-1.42, P < 0.001), clinical conditions including traffic-related cause of injury 1.22 (95 % CI, 1.02-1.45, P = 0.029), GCS moderate (GCS 9-12 compared to GCS 13-15) 4.33 (95 % CI, 3.13-5.99, P < 0.001), GCS severe (GCS 3-8 compared to GCS 13-15) 23.09 (95 % CI, 13.80-38.63, P < 0.001), abnormal pupillary light reflex 3.22 (95 % CI, 2.09-4.96, P < 0.001), hypotension after injury 2.88 (95 % CI, 1.06-7.81, P = 0.038), polytrauma 2.31 (95 % CI, 2.03-2.62, P < 0.001), surgical intervention 2.21 (95 % CI, 1.22-4.01, P = 0.009), pre-injury health conditions including pre-injury comorbidity 1.52 (95 % CI, 1.24-1.86, P = 0.0020), and pre-injury anti-thrombotic therapy 1.51 (95 % CI, 1.23-1.84, P < 0.001) were related to higher in-hospital mortality in elderly patients with TBI. Subgroup analyses according to multiple types of anti-thrombotic drugs with at least two included studies showed that anticoagulant therapy 1.70 (95 % CI, 1.04-2.76, P = 0.032), Warfarin 2.26 (95 % CI, 2.05-2.51, P < 0.001), DOACs 1.99 (95 % CI, 1.43-2.76, P < 0.001) were related to elevated mortality. Dose-response meta-analysis of age found an odds ratio of 1.029 (95 % CI, 1.024-1.034, P < 0.001) for every 1-year increase in age on in-hospital mortality.

CONCLUSIONS

In the field of elderly patients with TBI, the overall in-hospital mortality and its temporal-spatial feature, the subgroup in-hospital mortalities according to injury severity, and dose-response meta-analysis of age were firstly comprehensively summarized. Substantial key risk factors, including the ones previously not elucidated, were identified. Our study is thus of help in underlining the importance of treating elderly TBI, providing useful information for healthcare providers, and initiating future management guidelines. This work underscores the necessity of integrating elderly TBI treatment and management into broader health strategies to address the challenges posed by the aging global population.

Is surgical rib fixation in patients aged more than 65 years old associated with worse outcomes compared to younger patients? A retrospective single-center study

BACKGROUND

There is no robust data regarding rib fixation in elderly patients. The aim of this study is to compare the postoperative outcomes of patients aged less and more than 65 years old.

METHODS

Patients operated from January 2012 to December 2018 were retrospectively analyzed. The following data were collected: age, sex, comorbidities, smoking habit, Injury Severity Score (ISS), number of fractured ribs, indication for surgery, associated injuries, time from trauma to surgery, number of fixed ribs, intrathoracic injuries, duration of intubation, ICU stay, postoperative cardiopulmonary complications, blood transfusion, overall and 30-day mortality, length of stay.

RESULTS

There was no difference regarding the ISS (p = 0.09), the number of rib fractures (p = 0.291), the indication for surgery, the number of fixed ribs (p = 0.819), the ICU stay (p = 0.096), the postoperative intubation duration (p = 0.059), the cardiopulmonary complications (p = 0.273) and perioperative blood transfusions (p = 0.34). Elderly patients presented more postoperative cognitive complications (p < 0.001). There was no difference in terms of overall mortality (p = 0.06) and 30-day mortality (p = 0.69). Elderly patients stayed longer in the hospital (p < 0.001).

CONCLUSIONS

The outcomes of rib fixation in the elderly patients are comparable to younger patients. However, elderly patients experience more frequently postoperative cognitive complications and their hospitalizations are longer.

Clinical Outcome and Management for Geriatric Traumatic Injury: Analysis of 2688 Cases in the Emergency Department of a Teaching Hospital in Taiwan

Geriatric traumatic injuries in emergency departments are frequent and associated with higher mortality rates and catastrophic functional outcomes. Several prediction scores have been established to manage traumatic patients, including the shock index (SI), revised trauma score (RTS), injury severity score (ISS), trauma injury severity score (TRISS), and new injury severity score (NISS). However, it was necessary to investigate the effectiveness and efficiency of care for the geriatric traumatic population. In addition, image studies such as computed tomography and magnetic resonance imaging play an important role in early diagnosis and timely intervention. However, few studies focus on this aspect. The association between the benefit of carrying out more image studies and clinical outcomes remains unclear. In this study, we included a total of 2688 traumatic patients and analyzed the clinical outcomes and predicting factors in terms of geriatric trauma via pre-hospital and in-hospital analysis. Our evaluation revealed that a shock index ≥1 may be not a strong predictor of geriatric trauma due to the poor physical response in the aging population. This should be modified in geriatric patients. Other systems, like RTS, ISS, TRISS, and NISS, were significant in terms of predicting the clinical outcome.

Have outcomes improved in trauma patients age 90 years and older over the past decade: Experience at a level II trauma center

INTRODUCTION

Managing trauma in the elderly is challenging and requires a multidisciplinary team approach. The aim of this study is to characterize and compare outcomes in patients 90 years and older in the last two decades.

METHODS

Retrospective review of trauma patients 90 years and older admitted from 1996 to 2015. The patients were divided into two groups: Early Decade (ED) and Late Decade (LD).

RESULTS

A total of 1697 patients were recorded, 551 (ED) and 1146 (LD). The mean age was 92.92 ± 8(90-108)[ED] and 92.9 ± 2.7(90-105)[LD] years. The most common mechanism and type of injury was falls and extremity trauma. Hospital length of stay (LOS) was shorter in the LD. There was no significant difference in in-hospital mortality or ICU LOS.

CONCLUSION

Trauma admission has increased in the last decade. However, in-hospital mortality remains low. It is important for multidisciplinary teams to allocate resources to treat this elderly population.
