The Patient Experience of Adolescents With Traumatic Injuries: Recommendations for Improvement.

GOAL: Positive patient experience is associated with less healthcare utilization, better treatment adherence, increased likelihood of returning to the same hospital, and fewer complaints. However, hospitals have been able to collect few insights into the experiences of pediatric patients due to age limitations. As an exception to that reality, adolescents (aged 12-20 years) are able to share their experiences and recommend improvements, yet little is known about their hospital experiences with traumatic injuries. We examined the patient experience of adolescents with traumatic injuries and collected their recommendations for improving care. METHODS: We conducted 28 semistructured interviews with English-speaking adolescents hospitalized at two trauma Level 1 hospitals (pediatric and adult) for physical injuries from July 2018 to June 2021. Interviews were transcribed and analyzed using modified thematic analysis. PRINCIPAL FINDINGS: The patients expressed three basic desires: (1) autonomy and active involvement in their care, (2) human connections with their clinicians, and (3) minimal discomfort. Study participants provided actionable recommendations for improving the patient experience for adolescents with traumatic injuries. PRACTICAL APPLICATIONS: Hospital administrators and clinicians can improve the patient experience for adolescents in their care by sharing information, expectations, and goals with them. Hospital administrators can also empower the clinical staff to connect with adolescents with traumatic injuries on a personal level.

Outpatient Opioid Prescriptions are Associated With Future Substance Use Disorders and Overdose Following Adolescent Trauma.

OBJECTIVE: This study aims to determine if outpatient opioid prescriptions are associated with future SUD diagnoses and overdose in injured adolescents 5 years following hospital discharge. SUMMARY OF BACKGROUND DATA: Approximately, 1 in 8 adolescents are diagnosed with an SUD and 1 in 10 experience an overdose in the 5 years following injury. State laws have become more restrictive on opioid prescribing by acute care providers for treating pain, however, prescriptions from other outpatient providers are still often obtained. METHODS: This was a retrospective cohort study of patients ages 12-18 admitted to 2 level I trauma centers. Demographic and clinical data contained in trauma registries were linked to a regional database containing 5 years of electronic health records and prescription data. Regression models assessed whether number of outpatient opioid prescription fills after discharge at different time points in recovery were associated with a new SUD diagnosis or overdose, while controlling for demographic and injury characteristics, and depression and posttraumatic stress disorder diagnoses. RESULTS: We linked 669 patients (90.9%) from trauma registries to a regional health information exchange database. Each prescription opioid refill in the first 3 months after discharge increased the likelihood of new SUD diagnoses by 55% (odds ratio: 1.55, confidence interval: 1.04-2.32). Odds of overdose increased with ongoing opioid use over 2-4 years post-discharge ( P = 0.016-0.025). CONCLUSIONS: Short-term outpatient opioid prescribing over the first few months of recovery had the largest effect on developing an SUD, while long-term prescription use over multiple years was associated with a future overdose.

National Cancer Institute Centers and Society of Surgical Oncology Cancer Research Synergy.

BACKGROUND: The objective of this study was to examine the influence of Surgical Society Oncology (SSO) membership and National Cancer Institute (NCI) status on the academic output of surgical faculty. METHODS: NCI cancer program status for each department of surgery was identified with publically available data, whereas SSO membership was determined for every faculty member. Academic output measures such as NIH funding, publications, and citations were analyzed in subsets by the type of cancer center (NCI comprehensive cancer center [CCC]; NCI cancer center [NCICC]; and non-NCI center) and SSO membership status. RESULTS: Of the surgical faculty, 2537 surgeons (61.9%) were from CCC, whereas 854 (20.8%) were from NCICC. At the CCC, 22.7% of surgeons had a history of or current NIH funding, compared with 15.8% at the NCICC and 11.8% at the non-NCI centers. The academic output of SSO members was higher at NCICC (52 ± 113 publications/1266 ± 3830 citations) and CCC (53 ± 92/1295 ± 4001) compared with nonmembers (NCICC: 26 ± 78/437 ± 2109; CCC: 37 ± 91/670 ± 3260), respectively, P < 0.05. Multivariate logistic regression revealed that SSO membership imparts an additional 22 publications and 270 citations, whereas NCI-designated CCC added 10 additional publications, but not citations. CONCLUSIONS: CCCs have significantly higher academic output and NIH funding. Recruitment of SSO members, a focus on higher performing divisions, and NIH funding are factors that non-NCI cancer centers may be able to focus on to improve academic productivity to aid in obtaining NCI designation.

Physical Examination is the Best Predictor of the Need for Abdominal Surgery in Children Following Motor Vehicle Collision.

BACKGROUND: Exploratory laparotomy in children after motor vehicle collision (MVC) is rare. In the absence of definitive hemorrhage or free abdominal air on radiographic imaging, predictors for operative exploration are conflicting. OBJECTIVE: The purpose of this study was to explore objective findings that may aid in determining which children require operative abdominal exploration after MVC. METHODS: Data from 2010-2014 at an American College of Surgeons-certified level 1 pediatric trauma center were retrospectively reviewed. Demographics, vital signs, laboratory data, radiologic studies, operative records, associated injuries, and outcomes were analyzed and p < 0.05 was considered statistically significant. RESULTS: Eight hundred sixty-two patients 0-18 years of age presented to the hospital after an MVC during the study period. Seventeen patients (2.0%) required abdominal exploration and all were found to have intraabdominal injuries. Respiratory rate was the only vital sign that was significantly altered (p = 0.04) in those who required abdominal surgery compared with those who did not. Physical examination findings, such as the seat belt sign, abdominal bruising, abdominal wound, and abdominal tenderness, were present significantly more frequently in those requiring abdominal surgery (p < 0.0001). Each finding had a negative predictive value for the need for operative exploration of at least 0.98. There were no significant differences in trauma laboratory values or radiographic findings between the 2 groups. CONCLUSION: Data from this study solidify the relationship between specific physical examination findings and the need for abdominal exploration after MVC in children. In addition, these data suggest that a lack of the seat belt sign, abdominal bruising, abdominal wounds, or abdominal tenderness are individually predictive of patients who will not require surgical intervention.

The Role of PhD Faculty in Advancing Research in Departments of Surgery.

OBJECTIVE: To determine the academic contribution as measured by number of publications, citations, and National Institutes of Health (NIH) funding from PhD scientists in US departments of surgery. SUMMARY BACKGROUND DATA: The number of PhD faculty working in US medical school clinical departments now exceeds the number working in basic science departments. The academic impact of PhDs in surgery has not been previously evaluated. METHODS: Academic metrics for 3850 faculties at the top 55 NIH-funded university and hospital-based departments of surgery were collected using NIH RePORTER, Scopus, and departmental websites. RESULTS: MD/PhDs and PhDs had significantly higher numbers of publications and citations than MDs, regardless of academic or institutional rank. PhDs had the greatest proportion of NIH funding compared to both MDs and MD/PhDs. Across all academic ranks, 50.2% of PhDs had received NIH funding compared with 15.2% of MDs and 33.9% of MD/PhDs (P < 0.001). The proportion of PhDs with NIH funding in the top 10 departments did not differ from those working in departments ranked 11 to 50 (P = 0.456). A greater percentage of departmental PhD faculty was associated with increased rates of MD funding. CONCLUSIONS: The presence of dedicated research faculty with PhDs supports the academic mission of surgery departments by increasing both NIH funding and scholarly productivity. In contrast to MDs and MD/PhDs, PhDs seem to have similar levels of academic output and funding independent of the overall NIH funding environment of their department. This suggests that research programs in departments with limited resources may be enhanced by the recruitment of PhD faculty.

A Novel Approach in Combined Liver and Kidney Transplantation With Long-term Outcomes.

OBJECTIVE: The aim of this study was to compare the outcomes of simultaneous and delayed implantation of kidney grafts in combined liver-kidney transplantation (CLKT). BACKGROUND DATA: Delayed function of the renal graft (DGF), which can result from hypotension and pressor use related to the liver transplantation (LT), may cause worse outcomes in CLKT. METHODS: A total of 130 CLKTs were performed at Indiana University between 2002 and 2015 and studied in an observational cohort study. All kidneys underwent continuous hypothermic pulsatile machine perfusion until transplant: 69 with simultaneous kidney transplantation (KT) (at time of LT, group 1) and 61 with delayed KT (performed at a later time as a second operation, group 2). All patients received continuous veno-venous hemodialysis during the LT. Propensity score match analysis in a 1:1 case-match was performed. RESULTS: Mean kidney cold ischemia time was 10 ± 3 and 50 ± 15 hours, for groups 1 and 2 (P < 0.0001), respectively. The rate of DGF was 7.3% in group 1, but no DGF was seen in group 2 (P = 0.0600). Kidney function was significantly better in group 2, if the implantation of kidneys was delayed >48 hours (P < 0.01). Patient survival was greater in group 2 at 1 year (91%), and 5 year (87%) post-transplantation (P = 0.0019). On multivariate analysis, DGF [hazard ratio (HR), 165.7; 95% confidence interval (CI), 9.4-2926], extended criteria donor kidneys (HR, 15.9; 95% CI 1.8-145.2), and recipient hepatitis C (HR, 5.5; 95% CI 1.7-17.8) were significant independent risk factors for patient survival. CONCLUSIONS: Delayed KT in CLKT (especially if delayed >48 h) is associated with improved kidney function with no DGF post-KT, and improved patient and graft survival.

Variation in Surgical Antibiotic Prophylaxis for Outpatient Pediatric Urological Procedures at United States Children's Hospitals.

PURPOSE: Guidelines recommend surgical antibiotic prophylaxis for clean-contaminated procedures but none for clean procedures. The purpose of this study was to describe variations in surgical antibiotic prophylaxis for outpatient urological procedures at United States children's hospitals. MATERIALS AND METHODS: Using the PHIS (Pediatric Health Information System®) database we performed a retrospective cohort study of patients younger than 18 years who underwent clean and/or clean-contaminated outpatient urological procedures from 2012 to 2014. We excluded those with concurrent nonurological procedures or an abscess/infected wound. We compared perioperative antibiotic charges for clean vs clean-contaminated procedures using a multilevel logistic regression model with a random effect for hospital. We also examined whether hospitals that were guideline compliant for clean procedures, defined as no surgical antibiotic prophylaxis, were also compliant for clean-contaminated procedures using the Pearson correlation coefficient. We examined hospital level variation in antibiotic rates using the coefficient of variation. RESULTS: A total of 131,256 patients with a median age of 34 months at 39 hospitals met study inclusion criteria. Patients undergoing clean procedures were 14% less likely to receive guideline compliant surgical antibiotic prophylaxis than patients undergoing clean-contaminated procedures (OR 0.86, 95% CI 0.84-0.88, p <0.0001). Hospitals that used antibiotics appropriately for clean-contaminated procedures were more likely to use antibiotics inappropriately for clean procedures (r = 0.7, p = 0.01). Greater variation was seen for hospital level compliance with surgical antibiotic prophylaxis for clean-contaminated procedures (range 9.8% to 97.8%, coefficient of variation 0.36) than for clean procedures (range 35.0% to 98.2%, coefficient of variation 0.20). CONCLUSIONS: Hospitals that used surgical antibiotic prophylaxis appropriately for clean-contaminated procedures were likely to use surgical antibiotic prophylaxis inappropriately for clean procedures. More variation was seen in hospital level guideline compliance for clean-contaminated procedures.

Impact of Integrated Vascular Residencies on Academic Productivity within Vascular Surgery Divisions.

BACKGROUND: Changing training paradigms in vascular surgery have been introduced to reduce overall training time. Herein, we sought to examine how shortened training for vascular surgeons may have influenced overall divisional academic productivity. METHODS: Faculty from the top 55 surgery departments were identified according to National Institutes of Health (NIH) funding. Academic metrics of 315 vascular surgery, 1,132 general surgery, and 2,403 other surgical specialties faculty were examined using institutional Web sites, Scopus, and NIH Research Portfolio Online Reporting Tools from September 1, 2014, to January 31, 2015. Individual-level and aggregate numbers of publications, citations, and NIH funding were determined. RESULTS: The mean size of the vascular divisions was 5 faculty. There was no correlation between department size and academic productivity of individual faculty members (R2 = 0.68, P = 0.2). Overall percentage of vascular surgery faculty with current or former NIH funding was 20%, of which 10.8% had major NIH grants (R01/U01/P01). Vascular surgery faculty associated with integrated vascular training programs demonstrated significantly greater academic productivity. Publications and citations were higher for vascular surgery faculty from institutions with both integrated and traditional training programs (48 of 1,051) compared to those from programs with integrated training alone (37 of 485) or traditional fellowships alone (26 of 439; P < 0.05). CONCLUSIONS: In this retrospective examination, academic productivity was improved within vascular surgery divisions with integrated training programs or both program types. These data suggest that the earlier specialization of integrated residencies in addition to increasing dedicated vascular training time may actually help promote research within the field of vascular surgery.

Utilizing Group-based Trajectory Modeling to Understand Patterns of Hemorrhage and Resuscitation.

OBJECTIVE: The purpose of this study was to describe variations in blood-based resuscitation in an injured cohort. We hypothesize that distinct transfusion trajectories are present. BACKGROUND: Retrospective studies of hemorrhage utilize the concept of massive transfusion, where a set volume of blood is required. Patterns of hemorrhage vary and massive transfusion does little to describe these differences. METHODS: Patients were prospectively included from June 2012 to 2013. Time of transfusion for each packed red blood cell (PRBC) transfused was recorded, in minutes, for all patients. Additional measures included demographic and injury data, admission laboratory values, and vital signs and outcomes including mortality, tempo of transfusion, and operative requirements. Group-based trajectory modeling was utilized to describe transfusion trajectories throughout the cohort. RESULTS: Three hundred sixteen patients met the inclusion criteria. Among them, 72% were men and median age was 35 years (interquartile range [IQR] 24-50), median injury severity score was 13 (IQR 9-22), median 24-hour transfusion volume was 4 units of PRBCs (IQR 2-8), and mortality was 14%. Six transfusion trajectories were identified. Among the patients, 35% received negligible transfusions (group 1). Groups 2 and 3 received greater than 15 units PRBCs-the former as early resuscitation, whereas the latter intermittently throughout the day. Groups 4 and 5 had similar small resuscitations with distinct demographic differences. Group 6 suffered blunt injuries and required rapid resuscitation. CONCLUSIONS: Traditional definitions of massive transfusion are broad and imprecise. In cohorts of severely injured patients, there are distinct, identifiable transfusion trajectories. Identification of subgroups is important in understanding clinical course and to anticipate resuscitative and therapeutic needs.

Trajectory subtypes after injury and patient-centered outcomes.

BACKGROUND: The recent focus on patient-centered outcomes highlights the need to better describe recovery trajectories after injury. The purpose of this study was to characterize recovery trajectory subtypes that exist after non-neurologic injury. MATERIALS AND METHODS: A prospective, observational cohort of 500 adults with an Injury Severity Score > 10 but without traumatic brain or spinal cord injury from 2009 to 2011 was formed. The Short Form-36 was administered at admission and repeated at 1, 2, 4, and 12 mo after injury. Group-based trajectory modeling was used to determine the number and shape of physical composite score (PCS) and mental composite score (MCS) trajectories. RESULTS: Three PCS trajectories and five MCS trajectories were identified. For PCS, trajectory 1 (10.4%) has low baseline scores, followed by no improvement over time. Trajectory 2 (65.6%) declines 1 mo after injury then improves over time. Trajectory 3 (24.1%) has a sharp decline followed by rapid recovery. For MCS, trajectory 1 (9.4%) is low at baseline and remains low. Trajectory 2 (14.4%) has a large decrease after injury and does not recover over the next 12 mo. Trajectory 3 (22.7%) has an initial decrease in MCS early, followed by continuous recovery. Trajectory 4 (19.1%) has a steady decline over the study period. Trajectory 5 (34.3%) stays consistently high at all time points. CONCLUSIONS: Recovery after injury is complex and results in multiple recovery trajectories. This has implications for patient-centered clinical trial design and in development of patient-specific interventions to improve outcomes.

Infectious complications in obese patients after trauma.

BACKGROUND: Obesity is a public health concern in the United States due to its increasing prevalence, especially in younger age groups. Trauma is the most common cause of death for people under aged 40 y. The purpose of this study is to determine the association between obesity and specific infectious complications after traumatic injury. MATERIALS AND METHODS: A retrospective analysis was conducted using data from the 2012 National Trauma Data Bank. The National Trauma Data Bank defined obesity as having a body mass index of 30 or greater. Descriptive statistics were calculated and stratified by obesity status. A hierarchical regression model was used to determine the odds of experiencing an infectious complication in patients with obesity while controlling for age, gender, diabetes, number of comorbidities, injury severity, injury mechanism, head injury, and surgical procedure. RESULTS: Patients with a body mass index of 30 or greater compared with nonobese patients had increased odds of having an infectious complication (Odds Ratio, 1.59; 1.49-1.69). In addition to obesity, injury severity score greater than 29, age 40 y or older, diabetes, comorbid conditions, and having a surgical procedure were also predictive of an infectious complication. CONCLUSIONS: Our results indicate that trauma patients with obesity are nearly 60% more likely to develop an infectious complication in the hospital. Infection prevention and control measures should be implemented soon after hospital arrival for patients with obesity, particularly those with operative trauma.

Tissue damage volume predicts organ dysfunction and inflammation after injury.

BACKGROUND: Multiply injured patients (MIPs) are at risk to develop multiple-organ failure (MOF) and prolonged systemic inflammation response syndrome (SIRS). It is difficult to predict which MIPs are at the highest risk to develop these complications. We have developed a novel method that quantifies the distribution and physical magnitude of all injuries identified on admission computed tomography scanning called the Tissue Damage Volume (TDV) score. We explored how individualized TDV scores corresponded to MOF and SIRS. MATERIALS AND METHODS: A retrospective study on 74 MIPs measured mechanical TDV by calculating injury volumes on admission computed tomography scans of all injuries in the head/neck, chest, abdomen, and pelvis. Regional and total TDV scores were compared between patients that did or did not develop MOF or sustained SIRS. The magnitude of organ dysfunction was also stratified by the magnitude of TDV. RESULTS: Mean total and pelvic TDV scores were significantly increased in patients who developed MOF. Mean total, chest, and abdominal TDV scores were increased in patients who developed sustained SIRS. The magnitude of organ dysfunction was significantly higher in patients who sustained large volume injuries in the pelvis or abdomen, and in patients who sustained injuries in at least three anatomic regions. CONCLUSIONS: A novel index that quantifies the magnitude and distribution of mechanical tissue damage volume is a patient-specific index that can be used to identify patients who have sustained injury patterns that predict progression to MOF and SIRS. The preliminary methods will need refinement and prospective validation.

Trends in paediatric sports-related injuries presenting to US emergency departments, 2001-2013.

This descriptive epidemiology study describes trends in paediatric sports-related injuries resulting from 21 selected sports presenting to US emergency departments (EDs) over a 13-year period. The study was a retrospective study using data from the US Consumer Product Safety Commission's National Electronic Injury Surveillance System (NEISS) for years 2001-2013. Inclusion criteria included people in the NEISS for injuries related to one of the 21 selected sports and between the ages of 5 and 18 years. Frequencies and linear regressions were calculated using provided sample weights. The results indicated there was a statistically significant increase of 10 010 nationally estimated selected sports-related injuries per year. Football, basketball, soccer and baseball resulted in 74.7% of the total national estimate for sports-related injuries presenting to US EDs for 2001-2013 for children aged 5-18 years. The results indicate that the number of paediatric sports-related injuries treated in US EDs has increased annually from 2001 to 2013.

Large-magnitude Pelvic and Retroperitoneal Tissue Damage Predicts Organ Failure.

BACKGROUND: Pelvic and retroperitoneal trauma is a major cause of morbidity and mortality in multiply injured patients. The Injury Severity Score (ISS) has been criticized for underrepresenting and inaccurately defining mechanical injury. The influence of pelvic injury volume on organ dysfunction and multiple organ failure (MOF) has not been described. Through the use of CT, this investigation sought to precisely define volumes of mechanical tissue damage by anatomic region and examine its impact on organ failure. QUESTIONS/PURPOSES: (1) Do patients with MOF have a greater volume of pelvic and retroperitoneal tissue damage when compared with those without MOF? (2) In patients who sustained pelvic trauma, does the magnitude of pelvic injury differ in patients with MOF? (3) Does the magnitude of organ dysfunction correlate with pelvic tissue damage volume? METHODS: Seventy-four multiply injured patients aged 18 to 65 years with an ISS ≥ 18 admitted to the intensive care unit for a minimum of 6 days with complete admission CT scans were analyzed. Each identifiable injury in the head/neck, chest, abdomen, and pelvis underwent volumetric determination using CT to generate regional tissue damage volume scores. Primary outcomes were the development of MOF as measured by the Denver MOF score and the degree of organ dysfunction by utilization of the Sequential Organ Failure Assessment (SOFA) score. Mean pelvic and retroperitoneal tissue damage volumes were compared in patients who developed MOF and those who did not develop MOF using Student's t-test. Among patients who sustained pelvic injuries, we compared mean volume of tissue damaged in patients who developed MOF and those who did not. We assessed whether there was a correlation between organ dysfunction, as measured by the SOFA score as a continuous variable, and the volume of pelvic and retroperitoneal tissue damage using the Pearson product-moment correlation coefficient. RESULTS: The average volume of tissue damage was greater in patients with MOF when compared with those without (MOF: 685.667 ± 1081.344; non-MOF: 195.511 ± 381.436; mean difference 490.156 cc [95% confidence interval {CI}, 50.076-930.237 cc], p = 0.030). Among patients who sustained pelvic injuries, those with MOF had higher average tissue damage volumes than those without MOF (MOF: 1322.000 ± 1197.050; non-MOF: 382.750 ± 465.005; mean difference 939.250 [95% CI, 229.267-1649.233], p = 0.013). Organ dysfunction (SOFA score) correlated with higher volumes of pelvic tissue damage (r = 0.570, p < 0.001). CONCLUSIONS: This investigation demonstrated that greater degrees of pelvic and retroperitoneal tissue damage calculated from injury CT scans in multiply injured patients is associated with more severe organ dysfunction and an increased risk of developing MOF. Early identification of polytrauma patients at risk of MOF allows clinicians to implement appropriate resuscitative strategies early in the disease course. Improved stratification of injury severity and a patient's anticipated clinical course may aid in the planning and execution of staged orthopaedic interventions. Future avenues of study should incorporate the ischemic/hypoperfusion component of pelvic injury in conjunction with the mechanical component presented here for improved stratification of multiply injured patients at higher risk of MOF. LEVEL OF EVIDENCE: Level III, prognostic study.

Emergency general surgery outcomes at safety net hospitals.

BACKGROUND: The United States hospital safety net is defined by the Agency for Healthcare Research and Quality as the top decile of hospitals, which see the greatest proportion of uninsured patients. These hospitals provide important access to health care for uninsured patients but are commonly believed to have worse outcomes. The aim of this study was to compare the outcomes of emergency general surgery procedures performed at safety net and nonsafety net hospitals. MATERIAL AND METHODS: The Healthcare Cost and Utilization Project Nationwide Inpatient Sample from 2008-2010 was used to create a cohort of inpatients who underwent emergency appendectomy, cholecystectomy, or herniorrhaphy. Outcomes measured included length of stay, charge, cost, death in hospital, complications, and failure to rescue (FTR). Univariate and logistic regression analysis was performed to associate variables with outcomes. RESULTS: A total of 187,913 emergency general surgery cases were identified, 11.5% of which were performed at safety net hospitals. The safety net cohort had increased length of stay but lower mean charge and cost. Age, comorbidity score, black race, male gender, and Medicaid and Medicare insurance were associated with mortality, complication, and FTR. Lower socioeconomic status was associated with mortality and complication. Safety net status was positively associated with complication but not mortality or FTR. CONCLUSIONS: Safety net hospitals had higher complication rates but no difference in FTR or mortality. This may mean that the hospitals are able to effectively recognize and treat patient complications and do so without increased cost.

The relationship between trauma center volume and in-hospital outcomes.

BACKGROUND: Increases in hospital volume are positively associated with improved surgical outcomes. However, in the trauma setting, studies have reported conflicting findings in regard to volume's effect on in-hospital mortality. This study investigates whether complications, failure-to-rescue (FTR), and mortality are influenced by trauma centers' average annual volume. METHODS: We performed a retrospective cohort study that analyzed patient records included in the National Trauma Data Bank from years 2008-2010. We calculated risk-adjusted complication, FTR, and mortality rates for centers treating different volumes of patients. We also performed multilevel logistic regression modeling to examine the probability that patients treated at trauma centers with higher annual volumes would experience complication, FTR, and mortality while controlling for injury severity, type of injury, mechanism of trauma, age, gender, race, number of comorbidities, head injury, hypotension, and hospital clustering. Hospital characteristics including designation level, academic status, nonprofit status, safety-net status, and region were incorporated into the model. RESULTS: Risk-adjusted complication, FTR, and mortality rates differed significantly across hospital volume quintiles. Regression analyses indicated that higher hospital volumes were significantly associated with a decreased likelihood of mortality for individual patient but not for complication or FTR. CONCLUSIONS: Our findings suggest that higher trauma center volume is associated with improved mortality outcomes. However, the relationship between volume and FTR is more complex. Future research should address the question of determining optimal volume levels that lead to high provider experience, efficient resource usage, and low unintended consequences or outcomes.

"Smoker's Paradox" in Patients Treated for Severe Injuries: Lower Risk of Mortality After Trauma Observed in Current Smokers.

BACKGROUND: Studies evaluating the effect of smoking status on mortality outcomes in trauma patients have been limited, despite the fact that survival benefits of smoking have been reported in other critical care settings. The phenomenon "smoker's paradox" refers to the observation that following acute cardiovascular events, such as acute myocardial infarction and cardiac arrest, smokers often experience decreased mortality in the hospital setting. The objective of our study was to determine whether smoking imparts a survival benefit in patients with traumatic injuries. METHODS: We performed a retrospective cohort study that analyzed cases included in the National Trauma Data Bank research dataset. Hierarchical logistic regression analyses were used to determine whether smoking alters the risk of mortality and complications in patients who smoke. RESULTS: The percentage of patients experiencing mortality differed significantly between smokers (n = 38,564) and nonsmokers (n = 319,249) (1.8% vs. 4.3%, P < .001); however, the percentage experiencing a major complication did not (9.7% vs. 9.6%, P = .763). Regression analyses indicated that smokers were significantly less likely to die during the hospital stay compared to nonsmokers after adjusting for individual and hospital factors (OR = 0.15; CI = 0.10, 0.22). Additionally, smokers were also less likely to develop a major complication than nonsmokers (OR = 0.73, CI = 0.59-0.91). CONCLUSIONS: Patients who smoke appear to have a much lower risk of in-hospital mortality than nonsmokers. Further investigation into biological mechanisms responsible for this effect should be carried out in order to potentially develop therapeutic applications.

Hanging and Strangulation Injuries: An Institutional Review From a Level 1 Pediatric Trauma Center.

BACKGROUND: We sought to define the incidence and outcomes of pediatric hanging and strangulation injuries to inform best practices for trauma triage and management. METHODS: A retrospective review was conducted that included all patients who presented after hanging or strangulation to a Level I Pediatric Trauma Center from 2011 through 2021. Patient demographics, injury characteristics, and clinical outcomes were collected. All imaging modalities of the head and neck were reviewed to determine if a bony fracture or vascular injury was present. RESULTS: Over the 11-year study period, 128 patients met inclusion criteria. The median age of the cohort was 13 years [IQR: 8.5-15], most patients were male (60.9%), and the median GCS was 11 [3, 15]. There were 96 cases (75%) that were intentional injuries. 76 patients (59.4%) received imaging in the form of plain radiographs, CT, or MRI of the neck and cervical spine. No fractures were identified and there were 0 clinically significant cervical spine injuries. CT angiograms of the neck identified no cerebral vascular injuries. Mortality was high (32%), and 25% of patients with nonaccidental injuries had a documented prior suicide attempt. CONCLUSION: We identified no cervical spine fractures and no blunt cerebral vascular injuries after a hanging or strangulation in over 10 years at a Level 1 Pediatric Trauma Center. Use of CT and CT angiography of the neck and cervical spine should be minimized in this patient population without high clinical index of suspicion and/or significant mechanism. LEVEL OF EVIDENCE: IV.

User-Guided Enhancements to a Technology-Facilitated Resilience Program to Address Opioid Risks Following Traumatic Injury in Youth: Qualitative Interview Study.

BACKGROUND: Youth with traumatic injury experience elevated risk for behavioral health disorders, yet posthospital monitoring of patients' behavioral health is rare. The Telehealth Resilience and Recovery Program (TRRP), a technology-facilitated and stepped access-to-care program initiated in hospitals and designed to be integrated seamlessly into trauma center operations, is a program that can potentially address this treatment gap. However, the TRRP was originally developed to address this gap for mental health recovery but not substance use. Given the high rates of substance and opioid use disorders among youth with traumatic injury, there is a need to monitor substance use and related symptoms alongside other mental health concerns. OBJECTIVE: This study aimed to use an iterative, user-guided approach to inform substance use adaptations to TRRP content and procedures. METHODS: We conducted individual semistructured interviews with adolescents (aged 12-17 years) and young adults (aged 18-25 years) who were recently discharged from trauma centers (n=20) and health care providers from two level 1 trauma centers (n=15). Interviews inquired about reactions to and recommendations for expanding TRRP content, features, and functionality; factors related to TRRP implementation and acceptability; and current strategies for monitoring patients' postinjury physical and emotional recovery and opioid and substance use. Interview responses were transcribed and analyzed using thematic analysis to guide new TRRP substance use content and procedures. RESULTS: Themes identified in interviews included gaps in care, task automation, user personalization, privacy concerns, and in-person preferences. Based on these results, a multimedia, web-based mobile education app was developed that included 8 discrete interactive education modules and 6 videos on opioid use disorder, and TRRP procedures were adapted to target opioid and other substance use disorder risk. Substance use adaptations included the development of a set of SMS text messaging-delivered questions that monitor both mental health symptoms and substance use and related symptoms (eg, pain and sleep) and the identification of validated mental health and substance use screening tools to monitor patients' behavioral health in the months after discharge. CONCLUSIONS: Patients and health care providers found the TRRP and its expansion to address substance use acceptable. This iterative, user-guided approach yielded novel content and procedures that will be evaluated in a future trial.

Pediatric cervical spine clearance: A 10-year evaluation of multidetector computed tomography at a level 1 pediatric trauma center.

INTRODUCTION: Efficient and accurate evaluation of the pediatric cervical spine (c-spine) for both injury identification and posttraumatic clearance remains a challenge. We aimed to determine the sensitivity of multidetector computed tomography (MDCT) for identification of cervical spine injuries (CSIs) in pediatric blunt trauma patients. METHODS: A retrospective cohort study was conducted at a level 1 pediatric trauma center from 2012 to 2021. All pediatric trauma patients age younger than 18 years who underwent c-spine imaging (plain radiograph, MDCT, and/or magnetic resonance imaging [MRI]) were included. All patients with abnormal MRIs but normal MDCTs were reviewed by a pediatric spine surgeon to assess specific injury characteristics. RESULTS: A total of 4,477 patients underwent c-spine imaging, and 60 (1.3%) were diagnosed with a clinically significant CSI that required surgery or a halo. These patients were older, more likely to be intubated, have a Glasgow Coma Scale score of <14, and more likely to be transferred in from a referring hospital. One patient with a fracture on radiography and neurologic symptoms got an MRI and no MDCT before operative repair. All other patients who underwent surgery including halo placement for a clinically significant CSI had their injury diagnosed by MDCT, representing a sensitivity of 100%. There were 17 patients with abnormal MRIs and normal MDCTs; none underwent surgery or halo placement. Imaging from these patients was reviewed by a pediatric spine surgeon, and no unstable injuries were identified. CONCLUSION: Multidetector computed tomography appears to have 100% sensitivity for detecting clinically significant CSIs in pediatric trauma patients, regardless of age or mental status. Forthcoming prospective data will be useful to confirm these results and inform recommendations for whether pediatric c-spine clearance can be safely performed based on the results of a normal MDCT alone. LEVEL OF EVIDENCE: Diagnostic Tests or Criteria; Level IV.
