Firearm trauma: Race and insurance influence mortality and discharge disposition.

BACKGROUND: Health insurance and race impact mortality and discharge outcomes in the general trauma population. It remains unclear if disparities exist by race and/or insurance in outcomes following firearm injuries. The purpose of this study was to assess differences in mortality and discharge based on race and insurance status following firearm injuries. METHODS: The National Trauma Data Bank (2007-2016) was queried for firearm injuries by International Classification of Diseases, Ninth/Tenth Revision, Ecodes. Patients with known discharge disposition, age (18-64 years), race, and insurance were included in analysis (N = 120,005). To minimize bias due to missing data, we used multiple imputation for variables associated with outcomes following traumatic injury: Injury Severity Score, Glasgow Coma Scale score, respiratory rate, systolic blood pressure, and sex. Multivariable regression analysis was additionally adjusted for age, sex, Injury Severity Score, intent, Glasgow Coma Scale score, systolic blood pressure, heart rate, respiratory rate, year, and clustered by facility to assess differences in mortality and discharge disposition. RESULTS: The average age was 31 years, 88.6% were male, and 50% non-Hispanic Blacks. Overall mortality was 11.5%. Self-pay insurance was associated with a significant increase in mortality rates in all racial groups compared with non-Hispanic Whites with commercial insurance. Hispanic commercial, Medicaid, and self-pay patients were significantly less likely to discharge with posthospital care compared with commercially insured non-Hispanic Whites. When examining racial differences in mortality and discharge by individual insurance types, commercially insured non-Hispanic Black and other race patients were significantly less likely to die compared with similarly insured non-Hispanic White patients. Regardless of race, no significant differences in mortality were observed in Medicaid or self-pay patients compared with non-Hispanic White patients. CONCLUSION: Victims of firearm injuries with a self-pay insurance status have a significantly higher rate of mortality. Hispanic patients regardless of insurance status were significantly less likely to discharge with posthospital care compared with non-Hispanic Whites with commercial insurance. Continued efforts are needed to understand and address the relationship between insurance status, race, and outcomes following firearm violence. LEVEL OF EVIDENCE: Prognostic and epidemiologic, Level IV.

Comparing Firearm and Stabbing Injuries in the Pediatric Trauma Population Using Propensity Matching.

OBJECTIVES: The objective of this study was to compare differences in mortality and nonhome discharge in pediatric patients with firearm and stab injuries, while minimizing bias. Our secondary objective was to assess the influence of insurance on these same outcomes. METHODS: Patients aged 0 to 17 years included in the National Trauma Data Bank (2007-2015) with firearm and stabbing injury were matched by propensity score. Logistic regression was used to assess associations of injury type and insurance with long-term care discharge and death. RESULTS: The average age was 14.8 years, 19.2% were female, 48% were African American, 58.4% had an injury severity score ≤8, and assaults accounted for 73.1% of cases. Firearm injuries were associated with a higher risk of discharge to long-term care (adjusted odds ratio [aOR], 2.07) compared with propensity-matched patients who were stabbed. Similarly, we found a higher risk of mortality in those with firearm injuries compared with stabbing injuries (aOR, 1.85). Regardless of mechanism, self-pay insurance status was associated with a higher risk of mortality (aOR, 2.41). When compared with stab wound patients with commercial insurance, self-pay firearm-injured patients were found to have an increased risk of mortality (aOR, 5.25). CONCLUSIONS: Pediatric victims of firearm violence were more likely to die or need additional care outside the home than victims of other types of penetrating injury when accounting for confounding characteristics to minimize bias.

Use of Chest Computed Tomography for Blunt Pediatric Chest Trauma: Does It Change Clinical Course?

INTRODUCTION: Given the concern for radiation-induced malignancy in children and the fact that risk of severe chest injury in children is low, the risk/benefit ratio must be considered in each child when ordering a computed tomography (CT) scan after blunt chest trauma. METHODS: The study included pediatric blunt trauma patients (age, <15 years) with chest radiograph (CR) before chest CT on admission to our adult and pediatric level I trauma center. Surgeons were asked to view the blinded images and reads and indicate if they felt CT was warranted based on CR findings, if their clinical management change based on additional findings on chest CT, and how they might change management. RESULTS: Of the 127 patients identified, 64.6% had no discrepancy between their initial CR and chest CT and 35.4% of the children's imaging contained a discrepancy. The majority of the pediatric and general trauma surgeons felt CT was indicated in 6 of 45 patients based on CR. In 87% of patients with a discrepancy in findings on CR and CT, the majority of surgeons agreed that their management would not change based on the additional information. In the 6 patients in which the CT was considered indicated, 4 of the 6 would have triggered a management change. CONCLUSIONS: Our study suggests that chest CT scans frequently serve as confirmatory diagnostic tools and in the pediatric blunt chest trauma patient and can be withheld in many cases without hindering the management of an injured child.

Incidence and Profile of Severe Cycling Injuries After Bikeway Infrastructure Changes.

The objective of this study was to evaluate whether bicycling infrastructure changes in the city of Minneapolis effectively reduced the incidence or severity of traumatic bicycling related injuries sustained by patients admitted to our Level 1 Trauma Center. Data for this retrospective cohort study was obtained from the trauma database at our institution and retrospective chart review. The total number of miles of bikeway in the city on a yearly basis was used to demonstrate the change in cycling infrastructure. Adjusted regression analysis demonstrated a significant reduction in ISS when total bike lane miles increased (Coef. - 0.04, P < 0.001). Increasing bike lane miles was also associated with a significant reduction in severe head injury (OR 0.99, P < 0.001) and ICU LOS (Coef. - 0.17, P = 0.013). The miles of bike lanes were not associated with any significant changes in mortality or mechanical ventilation days when adjusted for other factors. We were able to demonstrate a reduction in the severity of injuries incurred by cyclists in the setting of a significant increase in the total number of bicycle lane miles. Our data lends credence to the existing evidence that the addition of bicycle lane miles increases cyclist safety.

The association between objectively-measured activity, sleep, call responsibilities, and burnout in a resident cohort.

BACKGROUND: When compared to the general US working population, physicians are more likely to experience burnout and dissatisfaction with work-life balance. Our aim was to examine the association of objectively-measured sleep, activity, call load, and gender with reported resident burnout and wellness factors. METHODS: Residents were recruited to wear activity tracker bands and complete interval blinded surveys. RESULTS: Of the 30 residents recruited, 28 (93%) completed the study. Based on survey results, residents who reported high amounts of call reported equivalent levels of wellness factors to those who reported low call loads. There was no association between amount of call on training satisfaction, emotional exhaustion, self-reported burnout, or sleep quality. Analysis of sleep tracker data showed that there was no significant association with time in bed, time asleep, times awakened or sleep latency and call load or self-reported burnout. Female gender, however, was found to be associated with self-reported burnout. No significant associations were found between objectively-measured activity and burnout. CONCLUSIONS: Based on the results of our study, there was no association with burnout and objectively-measured sleep, call volume, or activity. Increased call demands had no negative association with training satisfaction or professional fulfillment. This would suggest that more hours worked does not necessarily equate to increased burnout.

Impostor Phenomenon and Burnout in General Surgeons and General Surgery Residents.

OBJECTIVE: Impostor phenomenon (IP) characterizes feelings of self-doubt coupled with feelings that achievements were based on luck and a fear of being discovered as an intellectual fraud. Recently, studies have focused on IP in medical trainees and its association with burnout; however, this research has not yet been conducted on surgeons. This study addresses that gap by investigating the prevalence of IP and burnout in general surgeons and surgery residents. DESIGN: Participants completed two unlinked, blinded surveys. The first survey included demographics and scholarly activity, while the second included the Clance Impostor Phenomenon Scale (CIPS) and a validated, single-item burnout score. SETTING: Hennepin County Medical Center and University of Minnesota, Minneapolis, MN. PARTICIPANTS: General surgeons and general surgery residents at two teaching hospitals, one community-based (N = 46) and one university-based (N = 42). RESULTS: The majority of both surgeons and residents were male, Caucasian, and married. Residents scored significantly higher compared to faculty in nearly half of CIPS questions. The overall CIPS score was significantly higher in trainees as well (61 vs 51, p = 0.017). Burnout did not differ significantly between trainees (30%) and faculty (41%) (p = 0.545). We found no significant differences in gender or years of practice in those with clinical IP (CIPS >62), and logistic regression analysis showed burnout as the only significant association for clinical IP symptoms (OR 3.95, p = 0.017). CONCLUSIONS: Contrary to studies in other medical fields, female general surgery faculty and trainees were no more likely than males to display characteristics of IP. Residents did; however, score higher than faculty on overall CIPS score. While we cannot determine how burnout and IP directly impact each other, our study shows that both faculty and trainees experiencing burnout are more likely to report symptoms of IP.

The Affordable Care Act's Effect on Discharge Disposition of Racial Minority Trauma Patients in the United States.

BACKGROUND: Our aim was to examine the US trauma population before and after the Affordable Care Act (ACA), specifically examining racial disparities in insurance status as well as access to post-hospitalization care in the trauma population. MATERIALS AND METHODS: The National Trauma Data Bank was queried for all non-burn patients age 18 to 64. The patient data was grouped into pre-ACA (2012-2013) and post-ACA (2014-2015). Regression analysis was controlled for age, sex, race (when applicable), type of injury (blunt vs penetrating), ISS, shock, head injury, and mechanical ventilation and clustered by hospital. RESULTS: After ACA implementation, mortality decreased (2.4% from 2.6%, P < 0.001) and the number of patients discharged to acute care, nursing homes, and rehabilitation also decreased. Adjusting for age, sex, race, and injury-related variables associated with post-hospital care, the likelihood of discharge to acute care, skilled nursing, and rehab facilities decreased significantly post-ACA for all insurance and discharge destinations except those patients with private insurance discharging to rehab facilities. All uninsured patients as well as Caucasians with public insurance were more likely to die from their injuries than Caucasians with private insurance. After ACA, other minorities with private insurance had a higher mortality than privately-insured Caucasians. CONCLUSIONS: Despite an increase in the rate of insured trauma patients, after implementation of the affordable care act there was no increase in post-hospital care facility utilization, particularly for minorities. Uninsured trauma patients, who are more likely to be minorities, have not only decreased access to rehabilitation resources but also higher mortality.

Rural versus urban pediatric non-accidental trauma: different patients, similar outcomes.

OBJECTIVE: Our aim was to compare urban and rural non-accidental trauma for trends and characterize where injury prevention efforts can be focused. Pediatric trauma patients (age 0-14 years) at two level I adult and pediatric trauma centers, one rural and one urban, were included and data from the trauma registries at each center was abstracted. RESULTS: Of 857 pediatric admissions, 10% of injuries were considered non-accidental. The mean age for all non-accidental trauma patients was significantly lower than the overall pediatric trauma population (2.6 vs. 7.7 years, P < 0.001). Significantly more fatalities occurred in the non-accidental trauma cohort (5.7% vs. 1% P = 0.007). In nearly half of all non-accidental trauma patients, the primary insurance was government programs (49%) and 46% were commercial insurance. The proportion of government insurance in non-accidental trauma was higher in both urban and rural cohorts. There were similar rates of urban and rural patients sustaining non-accidental trauma who were uninsured (6.5 vs. 5.3%). Patients that were younger, in a rural location, and receiving government insurance were at higher risk of non-accidental trauma on univariable analysis. However, only age remained an independent predictor on multivariable analysis.

Occupational exposure during emergency department thoracotomy: A prospective, multi-institution study.

BACKGROUND: Occupational exposure is an important consideration during emergency department thoracotomy (EDT). While human immunodeficiency virus/hepatitis prevalence in trauma patients (0-16.8%) and occupational exposure rates during operative trauma procedures (1.9-18.0%) have been reported, exposure risk during EDT is unknown. We hypothesized that occupational exposure risk during EDT would be greater than other operative trauma procedures. METHODS: A prospective, observational study at 16 US trauma centers was performed (2015-2016). All bedside EDT resuscitation providers were surveyed with a standardized data collection tool and risk factors analyzed with respect to the primary end point, EDT occupational exposure (percutaneous injury, mucous membrane, open wound, or eye splash). Provider and patient variables and outcomes were evaluated with single and multivariable logistic regression analyses. RESULTS: One thousand three hundred sixty participants (23% attending, 59% trainee, 11% nurse, 7% other) were surveyed after 305 EDTs (gunshot wound, 68%; prehospital cardiopulmonary resuscitation, 57%; emergency department signs of life, 37%), of which 15 patients survived (13 neurologically intact) their hospitalization. Overall, 22 occupational exposures were documented, resulting in an exposure rate of 7.2% (95% confidence interval [CI], 4.7-10.5%) per EDT and 1.6% (95% CI, 1.0-2.4%) per participant. No differences in trauma center level, number of participants, or hours worked were identified. Providers with exposures were primarily trainees (68%) with percutaneous injuries (86%) during the thoracotomy (73%). Full precautions were utilized in only 46% of exposed providers, while multiple variable logistic regression determined that each personal protective equipment item utilized during EDT correlated with a 34% decreased risk of occupational exposure (odds ratio, 0.66; 95% CI, 0.48-0.91; p = 0.010). CONCLUSIONS: Our results suggest that the risk of occupational exposure should not deter providers from performing EDT. Despite the small risk of viral transmission, our data revealed practices that may place health care providers at unnecessary risk of occupational exposure. Regardless of the lifesaving nature of the procedure, improved universal precaution compliance with personal protective equipment is paramount and would further minimize occupational exposure risks during EDT. LEVEL OF EVIDENCE: Therapeutic/care management study, level III.

Long-Term Functional Outcomes after Traumatic Thoracic and Lumbar Spine Fractures.

The incidence of thoracolumbar spine fractures in blunt trauma is 4 to 5 per cent. These fractures may lead to neurologic injury, chronic back pain, and disability. Most studies from United States trauma centers focus on neurologic sequelae and/or compare treatment modalities. However, most patients with spine fractures do not have a neurologic deficit. Our primary objective was to determine the long-term outcome of traumatic thoracolumbar spine fractures, specifically addressing quality of life, chronic pain, and employment using a validated patient outcome survey. A chart review of 138 adult blunt trauma patients who sustained a thoracolumbar spine fracture and were admitted to our Level I trauma center from 2008 to 2013 was performed. A phone interview based on the Short-Form 12®, a general health survey, was then conducted. Of the 134 patients who met the inclusion criteria, 46 (34%) completed the survey. The average Short-Form 12® scores were 51.0 for the physical health component score and 52.9 for the mental health component score. These did not differ significantly from the national norm. Furthermore, 83 per cent (38) of the survey respondents returned to work full-time at the same level as before their injury. Majority of the patients (76%) said they did not have pain two to seven years after injury. Despite a commonly held belief that back injury leads to chronic pain and disability, after sustaining a thoracic or lumbar fracture, patients are generally able to return to work and have a comparable quality of life to the general population. This knowledge may be useful in counseling patients regarding expectations for recovery from trauma.

CT scan-detected pneumoperitoneum: an unreliable predictor of intra-abdominal injury in blunt trauma.

INTRODUCTION: Free intra-peritoneal air in blunt trauma is a classic sign associated with hollow viscus injury, traditionally mandating laparotomy. In blunt abdominal trauma, the CT scan has become the diagnostic modality of choice. The increased sensitivity of CT scans may lead to detection of free intra-peritoneal air that is not clinically significant. OBJECTIVE: To characterize conditions and findings that allow for the safe observation of blunt trauma patients with free air and to propose a patient management algorithm to decrease rates of non-therapeutic laparotomy. DESIGN: A retrospective review of 5877 blunt trauma patients who had an abdominal CT scan upon admission to our hospital from 2003 to 2011. A secondary CT review was performed by a single radiologist to further characterize the CT findings in the 74 patients with free air reported on initial scan. Management and hospital course were reviewed in these patients. RESULTS: Of the 74 patients with intra-abdominal free air, 36 patients with a benign clinical picture were observed and 38 patients underwent urgent exploratory laparotomy. Eleven patients received a non-therapeutic laparotomy. The majority (61%) of patients, 45 of 74, had free air and no significant injury suggesting the presence of benign free air. Patients who had intra-abdominal injury also typically had other clinical or radiologic signs of injury. Findings that were highly predictive of intra-abdominal injury in the setting of free air were free fluid (P<0.001), radiographic signs of bowel trauma (P<0.001) as well as clinical and/or radiographic seatbelt sign (P=0.004). CONCLUSIONS: CT scans may detect free air that is not always clinically significant. Free fluid, seatbelt sign or radiographic signs of bowel trauma in the presence of pneumoperitoneum is highly predictive of injury and these patients should be explored. Based on the results of our study, we created an algorithm to aid in identifying those patients with intra-abdominal free air who may be observed safely.
