Examining Violence Against Women at a Regional Level 1 Trauma Center During the COVID-19 Pandemic.

INTRODUCTION: There is a growing concern that certain public health restrictions imposed to prevent the spread of coronavirus disease 2019 (COVID-19) could result in more violence against women (VAW). We sought to determine if the rates and types of VAW changed during the COVID-19 pandemic at our level 1 trauma center (L1TC). METHODS: We performed a retrospective review of female patients who presented to our L1TC because of violence from 2019 through 2020. Patients were grouped into a pre-COVID or COVID period. The primary aim of this study was to compare rates of VAW between groups. Secondary aims sought to evaluate for any difference in traumatic mechanism between periods and to determine if a temporal relationship existed between COVID-19 and VAW rates. RESULTS: There was no difference in rates of VAW between the pre-COVID and COVID period (3.1% vs 3.6%, P = .6); however, rates of penetrating trauma were greater during the COVID period (38.2% vs 10.3%, P = .01). After controlling for patient age and race, the odds of penetrating trauma increased during the pandemic (OR 5.8, 95% CI 1.6-28.5, P < .01). From February 2020 through October 2020, there was a direct relationship between rates of COVID-19 and VAW (r2 .78, P < .01). CONCLUSION: Rates of VAW were unchanged between the pre-COVID and COVID periods, yet the odds of penetrating VAW were 5 times greater during the pandemic. Moving forward, trauma surgeons must remain vigilant for signs of violence and ensure that support services are available during future crises.

Obesity is associated with a reduced odds for blunt intra-abdominal injuries in children.

OBJECTIVES: Children with obesity may possess unique injury characteristics that may affect their emergency care. To better understand this relationship, we investigated the association of obesity in pediatric trauma patients and intra-abdominal injuries (IAIs) and routinely utilized emergency department (ED) diagnostic procedures (computed tomography (CT) scans and ultrasound (US) examinations). METHODS: This secondary data analysis utilized Pediatric Emergency Care Applied Research Network (PECARN) data from 2007 to 2010. Since height data were not available, children (2-17 years) with obesity were defined using weight-for-age percentiles. Non-parametric testing determined potential confounders. Adjusted odds ratios (aOR) were calculated using binary logistic regression for weight status and IAIs and diagnostic procedures. RESULTS: There were 3846 patients with actual weight recorded: 3301 (85.8%) children without obesity and 545 (14.2%) with obesity. Children with obesity had decreased odds for IAI after adjusting for race, mechanical force injury (MFI) type, vomiting, and abdominal wall trauma (adjusted odds ratio (aOR)=0.58 (95% CI 0.35-0.97); p-value=0.04). Patients with obesity had reduced odds for a CT examination. No association was found between obesity status and US utilization. African-American patients had decreased odds for IAIs, CT scans and US examinations after adjustment which could be related to MFI type. CONCLUSIONS: Obesity appears to reduce the odds for pediatric IAIs and CT scans, but not for US examinations. Selection bias is possible due to injury severity and missing or excluded weight data. Further research is needed in other pediatric populations with obesity and blunt injuries.

Youth and Young Adult Victims of Interpersonal Violence at LA County + USC Medical Center: A Review of Epidemiology and Recidivism.

Youth and young adult interpersonal violence (IPV) is a unique clinical challenge which merits study. This study defined the demographics and clinical outcomes of youth and young adult victims of IPV presenting to our hospital while examining violent injury recidivism. We reviewed patients aged 10 to 30 years admitted to our trauma bay as a victim of gunshot wound (GSW), stabbing wound, or blunt assault from 1998 to 2015 (n = 12,549). Logistic regression analysis was conducted to compare patient mortality across demographic characteristics, and Cox proportional hazards regression was used to determine risk factors for recidivism. Male (92%) and Hispanic patients (75%) constituted the majority of admissions. We observed differences in the mortality rate by gender (9% in males vs 5% in females, P < 0.001), race/ethnicity (5% non-Hispanic white vs 9% Hispanic, P = 0.001), insurance status (3% insured vs 10% uninsured, P < 0.001), and mechanism of injury (13% GSW, 2% stabbing wound, and 0.3% blunt assault, P < 0.001). Male gender, younger age, GSW, and amphetamine placed patients at higher risk for IPV recidivism (P < 0.05). This study demonstrates the need to better understand how demographics and economics are associated with youth and young adult IPV. In addition, future IPV prevention and intervention initiatives can be tailored to suit the unique needs of our population.

Acute Surgical Decision-Making in Abdominal Trauma Is Not Altered by Race or Socioeconomic Status.

Two main procedures are performed on patients suffering from colonic perforation, diverting colostomy and primary tissue repair. We investigated patient race, ethnicity, and socioeconomic status (SES) that predicted surgical outcomes after blunt or penetrating trauma. A retrospective analysis was performed using data from the National Trauma Data Bank for three years (2013-2015). We identified patients who presented with primary colonic injury and subsequent colon operation (n = 5431). Operations were grouped into three classes: colostomy, ileostomy, and nonostomy. Multiple linear and logistic regressions were performed to assess how race and insurance status are associated with the primary outcome of interest (ostomy formation) and secondary outcomes such as length of stay, time spent in ICU, and surgical site infection. Neither race/ethnicity nor insurance status proved to be reliable predictors for the formation of an ostomy. Patients who received either a colostomy or ileostomy were likely to have longer stays (OR [odds ratio]: 5.28; 95% CI [confidence interval]: 3.88-6.69) (OR: 11.24; 95% CI: 8.53-13.95), more time spent in ICU (2.73; 1.70-3.76) (7.98; 6.10-9.87), and increased risk for surgical site infection (1.32; 1.03-1.68) (2.54; 1.71-3.78). Race/ethnicity and SES were not reliable predictors for surgical decision-making on the formation of an ostomy after blunt and penetrating colonic injury. However, the severity of the injury as calculated by Injury Severity Score and the number of abdominal injuries were both associated with higher rates of colostomy and ileostomy. These data suggest that surgical decision-making is dependent on perioperative patient presentation and, not on race, ethnicity, or SES.

Validation of trauma scales: ISS, NISS, RTS and TRISS for predicting mortality in a Colombian population.

BACKGROUND: Our purpose was to validate the performance of the ISS, NISS, RTS and TRISS scales as predictors of mortality in a population of trauma patients in a Latin American setting. MATERIALS AND METHODS: Subjects older than 15 years with diagnosis of trauma, lesions in two or more body areas according to the AIS and whose initial attention was at the hospital in the first 24 h were included. The main outcome was inpatient mortality. Secondary outcomes were admission to the intensive care unit, requirement of mechanical ventilation and length of stay. A logistic regression model for hospital mortality was fitted with each of the scales as an independent variable, and its predictive accuracy was evaluated through discrimination and calibration statistics. RESULTS: Between January 2007 and July 2015, 4085 subjects were enrolled in the study. 84.2% (n = 3442) were male, the mean age was 36 years (SD = 16), and the most common trauma mechanism was blunt type (80.1%; n = 3273). The medians of ISS, NISS, TRISS and RTS were: 14 (IQR = 10-21), 17 (IQR = 11-27), 4.21 (IQR = 2.95-5.05) and 7.84 (IQR = 6.90-7.84), respectively. Mortality was 9.3%, and the discrimination for ISS, NISS, TRISS and RTS was: AUC 0.85, 0.89, 0.86 and 0.92, respectively. No one scale had appropriate calibration. CONCLUSION: Determining the severity of trauma is an essential tool to guide treatment and establish the necessary resources for attention. In a Colombian population from a capital city, trauma scales have adequate performance for the prediction of mortality in patients with trauma.

Racial Differences in Treatment Approaches and Mortality Following Arterial Trauma.

OBJECTIVES: We sought to evaluate the impact of race on treatment approaches and mortality following arterial trauma. METHODS: The National Trauma Data Bank (version 7.2, American College of Surgeons) was queried from 2002 to 2012 to identify patients aged 18 to 65 years with arterial trauma. The association between race (white, black, and Hispanic) and mortality following arterial injury was assessed, stratified by penetrating or blunt injury. Temporal trends in the use of open and endovascular procedures were evaluated across the racial groups. Multivariable regression models adjusting for patient demographics, injury severity, hospital characteristics, insurance status, and type of intervention performed were used to evaluate potential contributors to the association of race with mortality. RESULTS: The study cohort consisted of 58 626 patients (52% white, 31% black, and 17% Hispanic). A majority (57%) of patients had penetrating injuries, with black and Hispanic patients being more likely to sustain penetrating injuries (80% and 65%, respectively) compared to white patients (41%, P < .001). Overall, black patients had higher mortality for penetrating injuries (16.8% vs 13.0% vs 7.8%, P < .001) when compared to Hispanic and white patients, correspondingly. Over the study period, there was increasing use of endovascular and decreasing open surgical procedures for treatment of arterial trauma. This finding was similar across all groups studied. In multivariable analysis, black race was found to be associated with higher mortality compared to white for both penetrating (odds ratio [OR] 1.52, 95% confidence interval [CI] 1.33-1.75, P < .001) and blunt (OR 1.27 95%CI 1.09-1.47, P = .002) arterial trauma. CONCLUSION: Even after adjusting for potential confounders, minority patients had increased odds of mortality following arterial trauma compared to their white counterparts. Further studies are needed to understand and to eliminate these observed disparities in outcome.

Orbital blowout fracture location in Japanese and Chinese patients.

PURPOSE: To characterize the location of orbital blowout fractures in Asian individuals. METHODS: This was a retrospective review of 470 consecutive Asian patients with orbital blowout fractures who presented to four tertiary care hospitals in Japan and China. Computed tomography (CT) characterized the location and severity of fractures involving the medial wall, the orbital floor, and/or the maxilloethmoidal strut. RESULTS: A total of 475 orbital blowout fractures were identified. More than one fracture location was involved in 19% of all cases. The medial orbital wall was the most commonly involved location, presenting in 29 cases (61%), of which 204 (43%) were isolated medial blowout fractures. The orbital floor was the second most common location involved, present in 226 cases (48%) with 150 isolated orbital floor fractures (32%), while the maxilloethmoidal strut was involved in 45 cases (9%) with 30 of those being isolated strut fractures (6%). The majority of fractures (62%) were classified as moderately severe, whilst 14% were mild, and 24% were severe. Associated nasal fractures were present in 16% of the cases. CONCLUSIONS: Orbital blowout fractures in Japanese and Chinese individuals occur most commonly in the medial wall. This is in contrast to previous reports on white individuals, who tend to sustain fractures involving the orbital floor rather than the medial wall.

Minority trauma patients tend to cluster at trauma centers with worse-than-expected mortality: can this phenomenon help explain racial disparities in trauma outcomes?

OBJECTIVES: To determine whether minority trauma patients are more commonly treated at trauma centers (TCs) with worse observed-to-expected (O/E) survival. BACKGROUND: Racial disparities in survival after traumatic injury have been described. However, the mechanisms that lead to these inequities are not well understood. METHODS: Analysis of level I/II TCs included in the National Trauma Data Bank 2007-2010. White, Black, and Hispanic patients 16 years or older sustaining blunt/penetrating injuries with an Injury Severity Score of 9 or more were included. TCs with 50% or more Hispanic or Black patients were classified as predominantly minority TCs. Multivariate logistic regression adjusting for several patient/injury characteristics was used to predict the expected number of deaths for each TC. O/E mortality ratios were then generated and used to rank individual TCs as low (O/E <1), intermediate, or high mortality (O/E >1). RESULTS: A total of 556,720 patients from 181 TCs were analyzed; 86 TCs (48%) were classified as low mortality, 6 (3%) intermediate, and 89 (49%) as high mortality. More of the predominantly minority TCs [(82% (22/27) vs 44% (67/154)] were classified as high mortality (P < 0.001). Approximately 64% of Black patients (55,673/87,575) were treated at high-mortality TCs compared with 54% Hispanics (32,677/60,761) and 41% Whites (165,494/408,384) (P < 0.001). CONCLUSIONS: Minority trauma patients are clustered at hospitals with significantly higher-than-expected mortality. Black and Hispanic patients treated at low-mortality hospitals have a significantly lower odds of death than similar patients treated at high-mortality hospitals. Differences in TC outcomes and quality of care may partially explain trauma outcomes disparities.

Insurance-and race-related disparities decrease in elderly trauma patients.

BACKGROUND: Little focus is on health care disparities in the elderly, a population largely covered by public insurance. We characterized insurance type and race in elderly trauma patients to determine if lack of insurance or minority status predict increased mortality. METHODS: The National Trauma Data Bank (version 7.0) was queried for all adult blunt trauma patients. We divided patients into two cohorts (15-64 or ≥ 65 years) based on age for universal Medicare eligibility. Our primary outcome measure was in-hospital mortality. Multiple logistic regression was used to control for confounding variables. RESULTS: A total of 541,471 patients met inclusion criteria. Among younger patients, the most common insurance type was private (41.0%), with 26.9% uninsured. In contrast, the most common insurance type among older patients was Medicare (64.6%), with 6.0% uninsured. Within the younger cohort, private insurance (adjusted odds ratio [AOR], 0.6; p < 0.01) and other insurance (AOR, 0.8; p < 0.01) predicted reduced mortality, while Medicare predicted similar mortality (AOR, 1.1; p = 0.18) compared with no insurance. Black race (AOR, 1.4; p < 0.01) and Hispanic ethnicity (AOR, 1.4; p < 0.01) predicted higher mortality compared with white race. Within the older cohort, no insurance predicted similar mortality as Medicare (AOR, 1.0; p = 0.43), private insurance (AOR, 1.0; p = 0.51), and other insurance (AOR, 1.0; p = 0.71). Hispanic ethnicity predicted increased mortality (AOR, 1.4; p < 0.01), while Asian race was protective (AOR, 0.7; p = 0.01) compared with white race. CONCLUSION: Elderly trauma patients present primarily with Medicare, while younger trauma patients are mostly privately insured; elderly patients are four times more likely to be insured. Disparities caused by lack of insurance and minority race are reduced in elderly trauma patients. LEVEL OF EVIDENCE: Epidemiologic/prognostic study, level III.

Insurance status is a potent predictor of outcomes in both blunt and penetrating trauma.

BACKGROUND: Patients with penetrating injuries are known to have worse outcomes than those with blunt trauma. We hypothesize that within each injury mechanism there should be no outcome difference between insured and uninsured patients. METHODS: The National Trauma Data Bank version 7 was analyzed. Patients aged 65 years and older and burn patients were excluded. The insurance status was categorized as insured (private, government/military, or Medicaid) and uninsured. Multivariate analysis adjusted for insurance status, mechanism of injury, age, race, sex, injury severity score, shock, head injury, extremity injury, teaching hospital status, and year. RESULTS: A total of 1,203,243 patients were analyzed, with a mortality rate of 3.7%. The death rate was significantly higher in penetrating trauma patients versus blunt trauma patients (7.9% vs 3.0%; P < .001), and higher in the uninsured (5.3% vs 3.2%; P < .001). On multivariate analysis, uninsured patients had an increased odds of death than insured patients, in both penetrating and blunt trauma patients. Penetrating trauma patients with insurance still had a greater risk of death than blunt trauma patients without insurance. CONCLUSIONS: Insurance status is a potent predictor of outcome in both penetrating and blunt trauma.

Sickle cell trait as a risk factor for secondary hemorrhage in children with traumatic hyphema.

PURPOSE: To determine risk factors for secondary hemorrhage and poor visual outcome in children with traumatic hyphemas. METHODS: We reviewed 99 eyes of 97 children younger than 18 years who had been hospitalized for hyphema within 48 hours of blunt eye trauma. Inpatient records were examined for race, age, sickle cell trait status, size of hyphema and intraocular pressure at admission, secondary hemorrhage (rebleed of hyphema), and medications while hospitalized. Fifty-five eyes of 53 children had at least 1 month of follow-up or attained best-corrected visual acuity of 20/50 or better at their last outpatient visit. RESULTS: Among 99 eyes of 97 children with traumatic hyphema, secondary hemorrhage occurred in nine eyes (9%). Among 72 eyes of 70 African-American children, secondary hemorrhage occurred in nine eyes (14%), whereas in 27 eyes of 27 white children, there were no secondary hemorrhages. However, when the 14 eyes of 13 sickle cell trait-positive children were excluded from the African-American group, the 57 eyes of sickle cell trait-negative African-American and white children did not have any secondary hemorrhages. The sickle cell trait-positive group had secondary hemorrhages in nine of 14 eyes (64%), significantly (P < .005) different from the 0% rate in the 57 eyes of African-American sickle cell trait-negative and white children. The sickle cell trait-positive group also had higher intraocular pressure and permanent visual impairment. CONCLUSION: Sickle cell trait is a significant risk factor for secondary hemorrhage, increased intraocular pressure, and permanent visual impairment in children who have traumatic hyphemas following blunt trauma.

Black-white disparities in blunt trauma.

To uncover causes of increased mortality rates in black accident victims, patterns of injury and access to trauma care were compared between black and white patients. Over a 41-month period (February 1985 to June 1988), 2120 white and 468 black patients, each with an Injury Severity Score (ISS) > 14 as a result of blunt trauma, were admitted to a Level I regional trauma center, part of a statewide trauma system. Blacks were significantly older and more of them had premorbid illnesses. Although vehicular crashes accounted for the majority of injuries in both groups, blacks had significantly more injuries resulting from falls, pedestrian accidents, and assaults. Whereas 70.6% of whites were transported from the scene and 73% were transported by helicopter, 52.7% of blacks were transported from the scene and 44% by helicopter. Blacks made up 18% of the study group and accounted for 20% of deaths (mortality rate 17.3% for blacks and 14.9% for whites). Mortality was significantly increased for black patients admitted with a Glasgow Coma Scale (GCS) score > or = 13. Private medical insurance, available for 46.3% of black patients, accounted for 78% of payments for all trauma admissions. Increased mortality of black trauma patients may be related to risk factors (age, premorbid illness), increased rates of pedestrian accidents and falls, and disparities in access to Level I trauma centers.

The epidemiology of ruptured globes.

This retrospective study documented the demographics of 227 ruptured globes in 223 patients admitted to the Wills Eye Hospital over a two-year period from 1988 to 1990. The risk for a ruptured globe was greatest among 18-to-24-year-old men, during the noon to 8PM time frame, on Saturdays, and in the months of May, June, October, and November. The home was the most common injury setting, followed by the work place and assault. Twenty-four globes (11%) were enucleated within 11 weeks of hospital admission. These cases frequently were the result of assault, blunt-type injuries. A disproportionate number occurred in blacks.
