Impact of the COVID-19 Pandemic on the Incidence, Etiology, Demographics, and Treatment of Craniomaxillofacial Trauma.

To compare the incidence, etiology, demographics, and treatment of craniomaxillofacial (CMF) trauma before, during, and after COVID-19. Retrospective cohort. Eighty-three health care organizations across the United States. The TriNetX Research Network identified 77,977,880 patients during 2017 to 2022. CMF fractures and soft tissue injuries during March to August of each year, aligning with the 2020 pandemic lockdown, were analyzed. In 2020, compared to immediately prepandemic in 2019, there were significant reductions of -17.5% in facial fractures and -19.0% in soft tissue injuries (P < .001). Conversely, in 2021, both injury types increased by +16.7% and +16.3%, respectively, compared to 2020 (P < .001). Changes in injury mechanisms in 2020 included significant decreases in athletic injuries (-57.6%), falls (-16.8%), assaults (-15.5%), motor vehicle collisions (-8.7%), and pedestrian accidents (-6.9%) (P < .01), while off-road vehicle (+48.4%), bicycle (+16.2%), and motorcycle (+8.9%) accidents increased (P < .01). The 10- to 14- and 5- to 9-year-old age groups experienced the most substantial reductions in facial fractures (-39.7% and -29.9%, respectively) and soft tissue injuries (-29.2% and -28.3%, respectively) in 2020 compared to 2019 (P < .001). Operative management of fractures and soft tissue injuries dropped by -20.3% and -12.4%, respectively, in 2020 versus 2019, and then rebounded with +15.8% and +14.6% increases in 2021 compared to 2020 (P < .001). In 2022, compared to prepandemic rates of 2019, there were fewer patients with facial fractures (-2.8%), soft tissue injuries (-4.5%), and operative repairs (-6.9% for fractures, -1.2% for soft tissue injuries) (P < .03). CMF trauma decreased in 2020, with subsequent years showing a rebound to levels slightly below those immediately prior to pandemic onset. Changes in etiology, demographics, and treatment highlight the complex dynamics of traumatic injuries during periods of societal disruption.

The Effect of COVID-19 Shelter-in-Place Orders on Pediatric Craniofacial Trauma.

Objectives: To investigate the impacts of the shelter-in-place orders on the injury patterns among children with craniofacial trauma. Materials and Methods: Pediatric (<18 years old) craniofacial trauma cases presenting to a regional level I trauma center 1 year before and after the initiation of Washington's shelter-in-place order were retrospectively reviewed. Demographic and injury-related variables were recorded, and bivariate and logistic regression analyses were computed. Results: One hundred nineteen children were evaluated over 2-year period (46 pre- and 73 post-shelter-in-place and were comparable in age, gender, and ethnicity (p ≥ 0.17)). The distribution of injury mechanisms between pre- and post-shelter-in-place were significantly different (p = 0.02), with the largest proportional increase in falls (10.5%) and had higher rates of associated brain injury (p ≤ 0.02). After adjusting for effect modifiers and confounders, children presenting during the post-shelter-in-place period were more likely to have associated brain injuries (odds ratio 3.4, 95% confidence interval: 1.11-10.6, p = 0.03). Conclusions: Among pediatric craniofacial injury cases, the shelter-in-place order was associated with a higher likelihood of brain injury and significant changes in injury mechanisms, with a higher proportion of falls.

The DISTANCE study: Determining the impact of social distancing on trauma epidemiology during the COVID-19 epidemic-An interrupted time-series analysis.

The large-scale social distancing efforts to reduce SARS-CoV-2 transmission have dramatically changed human behaviors associated with traumatic injuries. Trauma centers have reported decreases in trauma volume, paralleled by changes in injury mechanisms. We aimed to quantify changes in trauma epidemiology at an urban Level I trauma center in a county that instituted one of the earliest shelter-in-place orders to inform trauma care during future pandemic responses. A single-center interrupted time-series analysis was performed to identify associations of shelter-in-place with trauma volume, injury mechanisms, and patient demographics in San Francisco, California. To control for short-term trends in trauma epidemiology, weekly level data were analyzed 6 months before shelter-in-place. To control for long-term trends, monthly level data were analyzed 5 years before shelter-in-place. Trauma volume decreased by 50% in the week following shelter-in-place (p < 0.01), followed by a linear increase each successive week (p < 0.01). Despite this, trauma volume for each month (March-June 2020) remained lower compared with corresponding months for all previous 5 years (2015-2019). Pediatric trauma volume showed similar trends with initial decreases (p = 0.02) followed by steady increases (p = 0.05). Reductions in trauma volumes were due entirely to changes in nonviolent injury mechanisms, while violence-related injury mechanisms remained unchanged (p < 0.01). Although the shelter-in-place order was associated with an overall decline in trauma volume, violence-related injuries persisted. Delineating and addressing underlying factors driving persistent violence-related injuries during shelter-in-place orders should be a focus of public health efforts in preparation for future pandemic responses. Epidemiological study, level III.

Temporal trends in patient characteristics, injury mechanisms and outcomes in pediatric trauma admissions between 2010 and 2017

IntroductionInjuries are a leading cause of preventable morbidity and mortality in children. Mechanisms of injuries and presentations are diverse in pediatric injuries and require special attention. Dedicated pediatric trauma care centers are ideal for management of children with injuries simultaneously serving as sources of research data. The objective of the current study was to identify changes in injury mechanisms, modifiable risk factors, and outcomes independently associated with admissions at a large pediatric trauma center in Tampa, Florida. MethodsWe conducted retrospective analysis of 8-years (2010-2017) of pediatric trauma admissions to a large trauma center. Demographic factors and injury characteristics were examined for temporal trends over two year increments. Temporal changes in admissions with major trauma, admission to ICU, and length of stay were examined using logistic regression analysis, and factors associated with independent temporal trends were identified using ordinal logistic regression modeling. ResultsDuring the study period, there were 4,934 trauma admissions with a predominance of falls (45.1%) and traffic injuries (20.5%). Trends were observed with less frequent head injuries (2010-2011: 35.7% vs 2016-2017: 28.3%, p < .01) and abdominal injuries (2010-2011:10.3% vs 2016-2017: 8.2%, p = .03), and more frequent chest injuries (2010-2011: 9.0% vs 2016-2017: 11.4%, p < .01). Over the study period, evaluated in 2-year increments, higher use of private insurance (Adjusted Odds Ratio (AOR)=1.44, 95% Confidence Interval (CI) 95% CI: 1.29-1.61) and helicopter transport (AOR=1.91, 95% CI: 1.58 -2.30) was observed. Admissions for drownings (AOR=1.50, 95% CI: 1.10 -2.02) and animal bites (AOR=1.99, 95% CI: 1.46 -2.71) increased during the study period. Improvement in patient outcomes (adjusted for injury severity) were observed with shorter, ≤1 day length of stay (LOS) (AOR=1.19, 95% CI: 1.06 -1.33), reduction in complications (AOR=0.47, 95% CI: 0.33 -0.66), and more admissions without an intensive care unit (ICU) stay (AOR=1.6 95% CI = 1.36 -1.88). ConclusionsSignificant reductions in LOS, ICU stay, and complications were temporally observed despite an increase in admissions with higher use of helicopter transport. These results can most likely be attributed to dedicated pediatric trauma experts and resources available at an integrated pediatric trauma center.

Evolution of high-energy pelvic trauma in southern Finland: a 12-year experience from a tertiary trauma centre

PurposeWe compared incidence, demographics, and injury mechanisms in severely injured patients with and without a pelvic ring fracture treated at a tertiary trauma centre. We also analyzed the changes in injury mechanisms that lead to high-energy pelvic trauma.MethodsData on severely injured adult patients (New Injury Severity Score [NISS] ≥16) from Helsinki Trauma Registry over the years 2006–2017 were reviewed. Patients with a pelvic ring fracture (PRF) and those without (N-PRF) were analyzed. Further subgrouping regarding time of the accident (2006–2009, 2010–2013, 2014–2017) was made. A comparison between groups was performed according to age, age > 60, gender, American Society of Anesthesiologists classification, injury scoring and mechanism, and 30-day in-hospital mortality.ResultsWe included 545 PRF and 1048 N-PRF patients. Pelvic ring fracture patients were more likely to be female (39% vs 22%, p < 0.001), to be more severely injured (NISS 35.2 vs 30.4, p < 0.001), injured due to a high fall (41% vs 25%, p < 0.001), to have self-inflicted injuries (23% vs 8%, p < 0.001), and to have higher 30-day in-hospital mortality (13% vs 9%, p = 0.005). During the study period, we noted increasing mean age and proportion of patients aged > 60, improvement in outcome (shown by decreasing 30-day in-hospital mortality rate) in both groups, and a decrease in motor vehicle accidents (MVAs) leading to pelvic trauma (30–16%).ConclusionsHigh-energy pelvic trauma can no longer be characterized as traffic accident injuries among young men. MVAs leading to pelvic trauma are decreasing and the most common injury mechanism is high fall. The patients are older and often female. Every fourth high-energy pelvic trauma was due to attempted suicide.

Time Trends of Head Injuries Over Multiple Seasons in Professional Male Football (Soccer).

The present study aimed to investigate time trends of head injuries and their injury mechanisms since a rule change as monitoring may help to identify causes of head injuries and may advance head injury prevention efforts. Based on continuously recorded data from the German football magazine “kicker Sportmagazin ® ” as well as other media sources, a database of head injuries in the 1 st German male Bundesliga was generated comprising 11 seasons (2006/07–2016/17). Injury mechanisms were analysed from video recordings. Injury incidence rates (IR) and 95% confidence intervals (95% CI) were calculated. Time trends were analysed via linear regression. Two hundred thirty-eight match head injuries occurred (IR 1.77/1000 match hours, 95% CI 1.56–2.01). There were no significant seasonal changes, expressed as annual average year-on-year change, in IRs over the 11-year period for total head injuries (p=0.693), facial/head fractures (p=0.455), lacerations/abrasions (p=0.162), and head contusions (p=0.106). The annual average year-on-year increase for concussion was 6.4% (p=0.004). Five head injury mechanisms were identified. There were no seasonal changes in injury mechanisms over the study period. The concussion subcategory increased slightly over the seasons, which may either be a result of increasing match dynamics or raised awareness among team physicians and players.

Evolution of a level I pediatric trauma center: Changes in injury mechanisms and improved outcomes

BackgroundTrauma is the leading cause of mortality among children, underscoring the need for specialized child-centered care. The impact on presenting mechanisms of injury and outcomes during the evolution of independent pediatric trauma centers is unknown. The aim of this study was to evaluate the impact of our single center transition from an adult to American College of Surgeons–verified pediatric trauma center. MethodsA retrospective analysis was performed of 1,190 children who presented as level I trauma activations between 2005 and 2016. Patients were divided into 3 chronological treatment eras: adult trauma center, early pediatric trauma center, and late pediatric trauma center after American College of Surgeons verification review. Comparisons were made using Pearson χ2, Wilcoxon rank sum, and Kruskal-Wallis tests. ResultsThe predominant mechanism of injury was motor vehicle crash, with increases noted in assault/abuse (2% adult trauma center, 11% late pediatric trauma center). A decrease in intensive care admissions was identified during late pediatric trauma center compared with early pediatric trauma center and adult trauma center (51% vs 62.4% vs 67%, P < .001), with concomitant increases in admissions to the floor and immediate operative interventions, but overall mortality was unchanged. ConclusionTransition to a verified pediatric trauma center maintains the safety expected of the American College of Surgeons certification, but with notable changes identified in mechanism of injury and improvements in resource utilization.

Epidemiology of Traumatic Deaths: Comprehensive Population‐Based Assessment

The epidemiology of traumatic deaths was periodically described during the development of the American trauma system between 1977 and 1995. Recognizing the impact of aging populations and the potential changes in injury mechanisms, the purpose of this work was to provide a comprehensive, prospective, population-based study of Australian trauma-related deaths and compare the results with those of landmark studies. All prehospitalization and in-hospital trauma deaths occurring in an inclusive trauma system at a single Level 1 trauma center [400 patients with an injury severity score (ISS) >15/year] underwent autopsy and were prospectively evaluated during 2005. High-energy (HE) and low-energy (LE) deaths were categorized based on the mechanism of the injury, time frame (prehospitalization, <48 hours, 2-7 days, >7 days), and cause [which was determined by an expert panel and included central nervous system-related (CNS), exsanguination, CNS + exsanguination, airway, multiple organ failure (MOF)]. Data are presented as a percent or the mean +/- SEM. There were 175 deaths during the 12-month period. For the 103 HE fatalities (age 43 +/- 2 years, ISS 49 +/- 2, male 63%), the predominant mechanisms were motor vehicle related (72%), falls (4%), gunshots (8%), stabs (6%), and burns (5%). In all, 66% of the patients died during the prehospital phase, 27% died after <48 hours in hospital, 5% died after 3 to 7 days in hospital, and 2% died after >7 days. CNS (33%) and exsanguination (33%) were the most common causes of deaths, followed by CNS + exsanguination (17%) and airway compromise 8%; MOF occurred in only 3%. Six percent of the deaths were undetermined. All LE deaths (n = 72, age 83 +/- 1 years, ISS 14 +/- 1, male 45%) were due to low falls. All LE patients died in hospital (20% <48 hours, 32% after 3-7 days, 48% after 7 days). The causes of deaths were head injury (26%) and complications of skeletal injuries (74%). The HE injury mechanisms, time frames, and causes in our study are different from those in the earlier, seminal reports. The classic trimodal death distribution is much more skewed to early death. Exsanguination became as frequent as lethal head injuries, but the incidence of fatal MOF is lower than reported earlier. LE trauma is responsible for 41% of the postinjury mortality, with distinct epidemiology. The LE group deserves more attention and further investigation.
