Pediatric Trauma Care Disparities: Association of Race and Sex With High Acuity Trauma Hospital Admissions.

INTRODUCTION: For adult trauma patients, the likelihood of receiving treatment at a hospital properly equipped for trauma care can vary by race and sex. This study examines whether a pediatric patient's race/ethnicity and sex are associated with treatment at a high acuity trauma hospital (HATH). MATERIALS AND METHODS: Using the 2017 National Inpatient Sample, we identified pediatric trauma patients ( ≤16 y) using International Classification of Diseases-10 codes. Because trauma centers are not defined in National Inpatient Sample, we defined HATHs as hospitals which transferred 0% of pediatric neurotrauma. We used logistic regression to examine associations between race/ethnicity, sex, age, and treatment at a HATH, adjusted for factors including Injury Severity Score, mechanism of injury, and region. RESULTS: Of 18,085 injured children (median Injury Severity Score 3 [IQR 1-8]), 67% were admitted to a HATH. Compared to White patients, Hispanic (odds ratio [OR] 0.85 [95% confidence interval [CI] 0.79-0.93]) and other race/ethnicity patients (OR 0.85 [95% CI 0.78-0.93]) had a significantly lower odds of treatment at a HATH. Children aged 2-11 (OR 1.36 [95% CI 1.27-1.46]) were more likely to be treated at a HATH compared to adolescents (age 12-16). After adjustment for other factors, sex was not associated with treatment at a HATH. CONCLUSIONS: Our study demonstrated racial and ethnic disparities in access to HATHs for pediatric trauma patients. Hispanic and other race/ethnicity pediatric trauma patients have lower odds of treatment at HATHs. Further research is needed to study the root causes of these disparities to ensure that all children with injuries receive equitable and high-quality care.

Early Repair of Rib Fractures Is Associated with Superior Length of Stay and Total Hospital Cost: A Propensity Matched Analysis of the National Inpatient Sample.

Background and Objectives: Previous studies have suggested that early scheduling of the surgical stabilization of rib fractures (SSRF) is associated with superior outcomes. It is unclear if these data are reproducible at other institutions. We hypothesized that early SSRF would be associated with decreased morbidity, length of stay, and total charges. Materials and Methods: Adult patients who underwent SSRF for multiple rib fractures or flail chest were identified in the National Inpatient Sample (NIS) by ICD-10 code from the fourth quarter of 2015 to 2016. Patients were excluded for traumatic brain injury and missing study variables. Procedures occurring after hospital day 10 were excluded to remove possible confounding. Early fixation was defined as procedures which occurred on hospital day 0 or 1, and late fixation was defined as procedures which occurred on hospital days 2 through 10. The primary outcome was a composite outcome of death, pneumonia, tracheostomy, or discharge to a short-term hospital, as determined by NIS coding. Secondary outcomes were length of hospitalization (LOS) and total cost. Chi-square and Wilcoxon rank-sum testing were performed to determine differences in outcomes between the groups. One-to-one propensity matching was performed using covariates known to affect the outcome of rib fractures. Stuart-Maxwell marginal homogeneity and Wilcoxon signed rank matched pair testing was performed on the propensity-matched cohort. Results: Of the 474 patients who met the inclusion criteria, 148 (31.2%) received early repair and 326 (68.8%) received late repair. In unmatched analysis, the composite adverse outcome was lower among early fixation (16.2% vs. 40.2%, p < 0.001), total hospital cost was less (USD114k vs. USD215k, p < 0.001), and length of stay was shorter (6 days vs. 12 days) among early SSRF patients. Propensity matching identified 131 matched pairs of early and late SSRF. Composite adverse outcomes were less common among early SSRF (18.3% vs. 32.8%, p = 0.011). The LOS was shorter among early SSRF (6 days vs. 10 days, p < 0.001), and total hospital cost was also lower among early SSRF patients (USD118k vs. USD183k late, p = 0.001). Conclusion: In a large administrative database, early SSRF was associated with reduced adverse outcomes, as well as improved hospital length of stay and total cost. These data corroborate other research and suggest that early SSRF is preferred. Studies of outcomes after SSRF should stratify analyses by timing of procedure.

Outcomes of Trauma "Walk-Ins" in the American College of Surgeons Trauma Quality Program Database.

BACKGROUND: Outcomes of trauma "walk-in" patients (using private vehicles or on foot) are understudied. We compared outcomes of ground ambulance vs walk-ins, hypothesizing that delayed resuscitation and uncoordinated care may worsen walk-in outcomes. METHODS: A retrospective analysis 2020 American College of Surgeons Trauma Quality Programs (ACS-TQP) databases compared outcomes between ambulance vs "walk-ins." The primary outcome was in-hospital mortality, excluding external facility transfers and air transports. Data was analyzed with descriptive statistics, bivariate, multivariable logistic regression, including an Inverse Probability Weighted Regression Adjustment with adjustments for injury severity and vital signs. The primary outcome for the 2019 (pre-COVID-19 pandemic) data was similarly analyzed. RESULTS: In 2020, 707,899 patients were analyzed, 556,361 (78.59%) used ambulance, and 151,538 (21.41%) were walk-ins. We observed differences in demographics, hospital attributes, medical comorbidities, and injury mechanism. Ambulance patients had more chronic conditions and severe injuries. Walk-ins had lower in-hospital mortality (850 (.56%) vs 23,131 (4.16%)) and arrived with better vital signs. Multivariable logistic regression models (inverse probability weighting for regression adjustment), adjusting for injury severity, demographics, injury mechanism, and vital signs, confirmed that walk-in status had lower odds of mortality. For the 2019 (pre-COVID-19 pandemic) database, walk-ins also had lower in-hospital mortality. DISCUSSION: Our results demonstrate better survival rates for walk-ins before and during COVID-19 pandemic. Despite limitations of patient selection bias, this study highlights the need for further research into transportation modes, geographic and socioeconomic factors affecting patient transport, and tailoring management strategies based on their mode of arrival.

Speed kills? Quantifying the association between police traffic stops, types of stops, and motor vehicle collisions.

BACKGROUND: Motor vehicle crashes (MVCs) are a leading cause of traumatic death and injury. Police traffic stops (PTS) are a common approach to enforcing motor vehicle laws intended to prevent MVCs. However, it is unclear which types of PTS are most effective. This study examined the relationship of PTS subtypes among municipal police patrols on non-interstate roads and MVCs and MVC-related deaths. METHODS: PTS subtype data were characterized from six North Carolina cities: Charlotte, Durham, Fayetteville, Greensboro, Raleigh, and Winston-Salem. The primary outcomes of this study were yearly non-interstate MVC and MVC-related death rates per 100 population. The data were analyzed as balanced time-series cross-sectional data. The statistical analysis accounted for time-dependent and city-dependent confounding. We used a two-way fixed effects model to analyze the relationship between PTS and MVC or MVC-related deaths. We also utilized the difference in difference (DID) analysis to analyze if the reduction of PTS following a 2012 policing administrative change in Fayetteville had an association with MVC or MVC-related deaths. RESULTS: We found no significant overall association between non-interstate PTS and MVCs (Coeff: -0.00006; p = 0.43) or MVC-related deaths (Coeff: -0.00011; p = 0.15). Panel regression suggested no significant relationship between MVCs and MVC-related deaths and PTS related to driving while impaired (p = 0.36), safe movement violation (p = 0.43), or seatbelt violations (p = 0.17). However, speed limit violations (Coeff: -0.00025; p = 0.032) and stop-light/sign violations (Coeff: -0.00147; p = 0.017) related to PTS significantly reduced MVC-related deaths. The DID regression showed no significant impact on MVCs (p = 0.924) or MVC-related deaths (0.706) before and after the police reform period. CONCLUSIONS: The evidence regarding the absence of an overall association and any association with most PTS subtypes suggest that PTS are not effective for MVC death prevention. Policymakers may proceed with exploring modifications to policing efforts without detriments to public safety as defined by MVC and MVC-related deaths. LEVEL OF EVIDENCE: Retrospective epidemiological study, level IV.

Benefit of balance? Odds of survival by unit transfused: Retrospective analysis of the ACS-TQIP database.

BACKGROUND: The critical blood shortage in January 2022 threatened the availability of blood. Utility of transfusion per unit was reported in a previous study, revealing patients receiving balanced transfusion are more likely to die after 16 units of packed red blood cells. We aimed to validate this study using a larger database. METHODS: Retrospective analysis utilizing the American College of Surgeons Trauma Quality Improvement Program was performed. Trauma patients aged ≥16 receiving transfusion within 4 hours of arrival were included and excluded if they died in the emergency department, received <2 units of packed red blood cells, did not receive fresh frozen plasma, or were missing data. Primary outcome was mortality. Subgroups were balanced transfusion if receiving ≤2:1 ratio of packed red blood cells:fresh frozen plasma, and unbalanced transfusion if >2:1 ratio. RESULTS: A total of 17,047 patients were evaluated with 28% mortality (4,822/17,408). Multivariable logistic regression identified advancing age (odds ratio 1.03 95% confidence interval 1.03-1.04), higher ISS (odds ratio 1.04, 95% confidence interval 1.03-1.04), and lower GCS (odds ratio 0.82, 95% confidence interval 0.82-0.83) as risk factors for mortality. Protective factors were balanced transfusion (odds ratio 0.81 95% confidence interval 0.71-0.93), male sex (odds ratio 0.90, 95% confidence interval 0.81-0.99), and blunt mechanism (odds ratio 0.74, 95% confidence interval 0.67-0.81). At 11 units of packed red blood cells, balanced transfusion patients were more likely to die (odds ratio 0.88, 95% confidence interval 0.80-0.98). Balanced transfusion patients survived at a higher rate for each unit of packed red blood cells, between 6 and 23 units of packed red blood cells. CONCLUSION: Mortality increases with each unit of packed red blood cell transfused. At 11 units of packed red blood cells, mortality is the more likely outcome. Balanced transfusion improves the chance of survival through 23 units of packed red blood cells.

Motor Vehicle Protective Device Usage Associated with Decreased Rate of Flail Chest: A Retrospective Database Analysis.

Background and Objectives: Protective equipment, including seatbelts and airbags, have dramatically reduced the morbidity and mortality rates associated with motor vehicle collisions (MVCs). While generally associated with a reduced rate of injury, the effect of motor vehicle protective equipment on patterns of chest wall trauma is unknown. We hypothesized that protective equipment would affect the rate of flail chest after an MVC. Materials and Methods: This study was a retrospective analysis of the 2019 iteration of the American College of Surgeons Trauma Quality Program (ACS-TQIP) database. Rib fracture types were categorized as non-flail chest rib fractures and flail chest using ICD-10 diagnosis coding. The primary outcome was the occurrence of flail chests after motor vehicle collisions. The protective equipment evaluated were seatbelts and airbags. We performed bivariate and multivariate logistic regression to determine the association of flail chest with the utilization of vehicle protective equipment. Results: We identified 25,101 patients with rib fractures after motor vehicle collisions. In bivariate analysis, the severity of the rib fractures was associated with seatbelt type, airbag status, smoking history, and history of cerebrovascular accident (CVA). In multivariate analysis, seatbelt use and airbag deployment (OR 0.76 CI 0.65-0.89) were independently associated with a decreased rate of flail chest. In an interaction analysis, flail chest was only reduced when a lap belt was used in combination with the deployed airbag (OR 0.59 CI 0.43-0.80) when a shoulder belt was used without airbag deployment (0.69 CI 0.49-0.97), or when a shoulder belt was used with airbag deployment (0.57 CI 0.46-0.70). Conclusions: Although motor vehicle protective equipment is associated with a decreased rate of flail chest after a motor vehicle collision, the benefit is only observed when lap belts and airbags are used simultaneously or when a shoulder belt is used. These data highlight the importance of occupant seatbelt compliance and suggest the effect of motor vehicle restraint systems in reducing severe chest wall injuries.

Lung Cancer in Young Patients is Associated With More Advanced Disease but Better Overall Survival.

INTRODUCTION: It is unclear whether nonsmall cell lung cancer (NSCLC) is associated with more aggressive disease and worse overall survival (OS) among younger patients. The aim of this study is to evaluate outcomes in young patients. We hypothesize that young age is associated with more advanced disease upon presentation, but better OS. METHODS: We identified patients with NSCLC from 2004 to 2018 in the National Cancer Database. Patients were categorized in 3 groups: age≤50, 51-84, and ≥85 y. The outcomes were OS, stage IV NSCLC and clinical nodal metastasis. OS was analyzed using multivariate cox and Kaplan-Meier analysis accounting for stage, comorbidities, and other factors. The association of age, presentation with stage IV NSCLC and node positivity was analyzed using multivariate logistic regression. RESULTS: In total 1,651,744 patients were identified: 92,506 (5.57%) age ≤50, 1,477,723 (88.90%) age 51-84, and 91,964 (5.53%) age ≥85. Multivariate model showed stage IV NSCLC was associated with age ≤50 (OR 1.17 (1.15-1.20) P < 0.001) and ≥85 (odds ratio (OR) 1.03 (1.02-1.04) P < 0.001). Clinical lymph node positivity was associated with age ≤50 (OR 1.27 (1.23-1.30) P < 0.001). Relative to patients 51-84, the ≤50 group was associated with better survival in Stage I (hazard ratio (HR) 0.61 versus 1.00), stage II (HR 1.12 versus 1.50), stage III (HR 2.12 versus 2.53), and stage IV (HR 6.65 versus 7.53). CONCLUSIONS: Patients ≤50-y-old present with more advanced NSCLC, but better OS compared to patients 51-84. These findings suggest the need for increased awareness regarding NSCLC among age groups seen as low risk.

Evaluating the Optimal Time Between Diagnosis and Surgical Intervention for Early-Stage Lung Cancer.

INTRODUCTION: There is no consensus on the optimal timing for lung cancer surgery. We aim to evaluate the impact of timing of surgical intervention. We hypothesize delay in intervention is associated with worse overall survival and higher pathologic upstaging in early-stage lung cancer. METHODS: We identified patients with cT1/2N0M0 nonsmall cell lung cancer in the National Cancer Database from 2004 to 2018. Patients were categorized by time to surgery groups: early (<26 d), average (26-60 d), and delayed (61-365 d). Primary outcome was overall survival and secondary outcome was pathologic upstaging. Multivariate models and survival analyses were used to determine factors associated with time from diagnosis to surgery, pathologic upstaging, and overall survival. RESULTS: In multivariate model, advanced age, non-Hispanic Black patients, nonprivate insurance, low median income and education, and treatment at low-volume facilities were less likely to undergo early intervention and compared to the average group were more likely to receive delayed intervention. Pathologic upstaging was more likely in the delayed group (odds ratio 1.11, 1.07-1.14) compared to early group (odds ratio 0.96, 0.93-0.99). Early intervention was associated with improved overall survival (hazard ratio 0.93, 0.91-0.95), while delayed intervention was associated with inferior survival (hazard ratio 1.11, 1.09-1.14). CONCLUSIONS: Expeditious surgical intervention is associated with lower rates of pathologic upstaging and improved overall survival in early-stage lung cancer. Delays in surgery are associated with social and economic factors, suggesting disparities in access to surgery. Lung cancer surgery should be performed as quickly as possible to maximize oncologic outcomes.

A prospective assessment of resilience in trauma patients using the Connor-Davidson Resilience Scale.

BACKGROUND: Resilience, or the ability to adapt to difficult or challenging life experiences, may be an important mediator in trauma recovery. The primary aim of this study was to describe resilience levels for trauma patients using the validated Connor-Davidson Resilience Scale. METHODS: Adult trauma patients admitted to a Level 1 trauma center (June 2022-August 2022) were surveyed at the time of admission and by phone between 2 weeks and 1 month after the original survey to obtain follow-up scores. We utilized the validated Connor-Davidson Resilience Scale score, a 25-question survey with 5 subfactors (Tenacity, Positive Outlook, Social Support, Problem Solving, and Meaning and Purpose). Each question was scored from 0 to 4 (maximum score 100, representing the highest resilience). Patient factors were collected from the electronic medical record and trauma health registry. Wilcoxon signed-rank test and multivariable linear regression were used to understand associations with Connor-Davidson Resilience Scale scores. RESULTS: We enrolled 98 patients. The median age was 50 years (interquartile range 32-67), and 74% were male sex. The baseline median Connor-Davidson Resilience Scale score on admission was 88 (interquartile range 81-94). Follow-up surveys (N = 64) showed a median score of 89.5 (80-90.5) (P = non-significant). No demographic variable was significantly associated with increasing baseline Connor-Davidson Resilience Scale score. Increased length of stay (ß = 1.03), insurance (ß = -7.50), and unknown race (ß = 23.69) were correlated with follow-up Connor-Davidson Resilience Scale scores. The subfactor "Meaning and Purpose" decreased at follow-up but was not statistically significant (P = .05). CONCLUSION: Validated tools that can accurately distinguish variability in resilience scores are needed for the trauma patient population to understand its relationship with long-term patient health outcomes.

Associations Between Psychiatric Diagnoses on Length of Stay and Mortality After Rib Fracture: A Retrospective Analysis.

INTRODUCTION: Concurrent psychiatric diagnoses adversely impact outcomes in surgical patients, but their relationship to patients with rib fracture after trauma is less understood. We hypothesized that psychiatric comorbidity would be associated with increases in hospital length of stay (LOS) and mortality risk after rib fracture. MATERIALS AND METHODS: The 2017 National Inpatient Sample was queried for adult patients who were admitted with rib fracture after trauma. Mental health disorders were categorized into 34 psychiatric diagnosis groups (PDGs) using clinical classifications software refined for International Classification of Diseases-10. Outcomes of interest were LOS and mortality. Bivariable analysis determined associations between PDGs, patient demographics, hospital characteristics, and outcomes. Logistic regression was performed to identify adjusted effects on mortality, and linear regression was performed to identify effects on LOS. RESULTS: Of 32,801 patients, median age was 61 y (IQR 46-76), and median LOS was 5 d (IQR 3-9). No PDGs were associated with increased odds of mortality. Concurrent diagnosis of schizophrenia spectrum (Coeff. 3.5, 95% CI 2.7-4.4, P < 0.001) or trauma- or stressor-related (Coeff. 1.6, 95% CI 0.9-2.5, P < 0.001) disorders demonstrated the greatest association with prolonged LOS. Increased odds of death and prolonged hospital stay were also associated with male sex, non-White patient race, and surgery occurring at urban and public hospitals. CONCLUSIONS: Psychiatric comorbidities are associated with death after rib fracture but are associated with increased LOS. These findings may help promote multidisciplinary patient management in trauma.

Digital learning: The reach of podcasts and YouTube on trauma surgery education.

BACKGROUND: Physicians, medical students, and health care professionals are charged with staying current throughout their training. No studies have examined the scope of trauma surgery-related podcasts and videos. Our goal was to characterize and evaluate the growing number of trauma-related podcasts and YouTube channels. METHODS: We conducted a search across 3 podcasting platforms (Google Podcasts, Apple Podcasts, and Spotify) and 1 video-sharing site (YouTube) for podcasts published up to November 11, 2022. We queued platforms for "Trauma" and "Trauma Surgery." We included podcasts or video channels in English that focused on trauma surgery or trauma survivorship and recovery. Descriptive analyses were used to determine the characteristics of podcasts and YouTube channels, reported as counts. RESULTS: We identified 91 podcasts and 103 YouTube channels dedicated to trauma recovery and/or trauma surgery. The longest running podcast was the "TraumaCast," and the oldest YouTube channel was "TraumaPro." The podcast with the most episodes was "Trauma Therapist," and the YouTube channel with the most episodes was the Arizona Trauma Association. Podcasts were aimed at public audiences, whereas YouTube channels focused on providers. A large proportion of content is not created by licensed professionals. CONCLUSIONS: Our study shows that popular trauma-focused podcasts target the general population, not health care professionals. The content creators behind these digital platforms seek to educate the public on the recovery process after traumatic injury. We must better understand the advantages and pitfalls of these ubiquitous resources.

Surgical subspecialization is associated with higher rate of rib fracture stabilization: a retrospective database analysis.

Background: Surgical stabilization of rib fractures (SSRF) is performed on only a small subset of patients who meet guideline-recommended indications for surgery. Although previous studies show that provider specialization was associated with SSRF procedural competency, little is known about the impact of provider specialization on SSRF performance frequency. We hypothesize that provider specialization would impact performance of SSRF. Methods: The Premier Hospital Database was used to identify adult patients with rib fractures from 2015 and 2019. The outcome of interest was performance of SSRF, defined using International Classification of Diseases-10th Revision Procedure Coding System coding. Patients were categorized as receiving their procedures from a thoracic, general surgeon, or orthopedic surgeon. Patients with missing or other provider types were excluded. Multivariate modeling was performed to evaluate the effect of surgical specialization on outcomes of SSRF. Given a priori assumptions that trauma centers may have different practice patterns, a subgroup analysis was performed excluding patients with 'trauma center' admissions. Results: Among 39 733 patients admitted with rib fractures, 2865 (7.2%) received SSRF. Trauma center admission represented a minority (1034, 36%) of SSRF procedures relative to other admission types (1831, 64%, p=0.15). In a multivariable analysis, thoracic (OR 6.94, 95% CI 5.94-8.11) and orthopedic provider (OR 2.60, 95% CI 2.16-3.14) types were significantly more likely to perform SSRF. In further analyses of trauma center admissions versus non-trauma center admissions, this pattern of SSRF performance was found at non-trauma centers. Conclusion: The majority of SSRF procedures in the USA are being performed by general surgeons and at non-trauma centers. 'Subspecialty' providers in orthopedics and thoracic surgery are performing fewer total SSRF interventions, but are more likely to perform SSRF, especially at non-trauma centers. Provider specialization as a barrier to SSRF may be related to competence in the SSRF procedures and requires further study. Type: Therapeutic/care management. Level of evidence: IV.

Are we waiting for the sky to fall? Predictors of withdrawal of life-sustaining support in older trauma patients: A retrospective analysis.

BACKGROUND: Limited data exist regarding the impact of advanced care planning for injured geriatric patients. We hypothesized that patients with advance directives limiting care (ADLC) compared with those without ADLC are more likely to undergo withdrawal of life-sustaining support (WLSS). METHODS: This is a propensity-matched analysis utilizing American College of Surgeons Trauma Quality Improvement Program patients 65 years or older who presented between 2017 and 2018. Patients with and without ADLC on admission were compared. The primary outcome was WLSS and days prior to WLSS. Additional factors examined included hospital length of stay (LOS), unplanned operations, unplanned intensive care unit admissions, and in-hospital cardiac arrests. Prior to matching, logistic regression model assessed factors associated with WLSS. Patients with and without ADLC were matched 1:1 via a propensity score using patient and injury factors as covariates, and matched pair analysis compared differences in WLSS between patients with and without ADLC. RESULTS: There were 597,840 patients included: 44,001 patients with an ADLC (7.36%) compared with 553,839 with no ADLC (92.64%). Patients with an ADLC underwent WLSS more often than those with no ADLC (7.68% vs. 2.48%, p < 0.001). In a 1:1 propensity-matched analysis, patients with ADLC were more likely to undergo WLSS (odds ratio [OR], 2.38' 95% confidence interval [CI], 2.22-2.55), although stronger predictors of WLSS included severity of injury (Injury Severity Score, 25+; OR, 23.84; 95% CI, 21.55-26.36), unplanned intensive care unit admissions (OR, 3.30; 95% CI, 2.89-3.75), and in-hospital cardiac arrests (OR, 4.97; 95% CI, 4.02-6.15). CONCLUSION: A small proportion of the geriatric trauma population had ADLC on admission. While ADLC was predictive of WLSS, adverse events were more strongly associated with WLSS. To ensure patient-centered care and reduce futile interventions, surgeons should delineate goals of care early regardless of ADLC. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

Challenges in closing the gap between evidence and practice: International survey of institutional surgical stabilization of rib fractures guidelines.

BACKGROUND: Surgical stabilization of rib fractures (SSRF) has gained increasing interest over the past decade, yet few candidates who could benefit from SSRF undergo operative management. We conducted an international survey of institutional SSRF guidelines comparing congruence between practice and contemporary evidence. We hypothesized that few guidelines reflect comprehensive evidence to facilitate standardized patient selection, operation, and postoperative management. METHODS: A request for institutional rib fracture guidelines was distributed from the Chest Wall Injury Society. Surgical stabilization of rib fractures-specific guideline contents were extracted using a priori-designed extraction sheets and compared against 28 SSRF evidence-based recommendations outlined by a panel of 14 international experts. Fisher's exact test compared the proportion of strong and weak evidence-based recommendations specified within a majority of institutional guidelines to evaluate whether strength of evidence is associated with implementation. RESULTS: A total of 36 institutions from 3 countries submitted institutional rib fracture management guidelines, among which 30 had SSRF-specific guidance. Twenty-eight guidelines (93%) listed at least one injury pattern criteria as an indication for SSRF, while 22 (73%) listed pain and 21 (70%) listed impaired respiratory function as other indications. Quantitative pain and respiratory function impairment thresholds that warrant SSRF varied across institutions. Few guidelines specified nonacute indications for SSRF or perioperative considerations. Seven guidelines (23%) detailed postoperative management but recommended timing and interval for follow-up varied. Overall, only 3 of the 28 evidence-based SSRF recommendations were specified within a majority of institutional practice guidelines. There was no statistically significant association ( p = 0.99) between the strength of recommendation and implementation within institutional guidelines. CONCLUSION: Institutional SSRF guidelines do not reflect the totality of evidence available in contemporary literature. Guidelines are especially important for emerging interventions to ensure standardized care delivery and minimize low-value care. Consensus effort is needed to facilitate adoption and dissemination of evidence-based SSRF practices. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Affordable Care Act Medicaid Expansion is Associated With Increased Utilization of Minimally Invasive Lung Resection for Early Stage Lung Cancer.

OBJECTIVE: Minimally invasive lung resection (MILR) is underutilized in the United States. Under the Affordable Care Act (ACA), 39 states adopted Medicaid expansion, while 12 did not. Although Medicaid expansion has been associated with improved access to cancer care, its effect on utilization of MILR is unclear. We hypothesize that MILR would increase in Medicaid expansion states. METHODS: The National Cancer Database was queried for adult patients from 2010 to 2018 with cT1/2N0M0 non-small cell lung cancer who received surgical resection by wedge, segmentectomy, or lobectomy. Patients were grouped by whether they received care in a state without Medicaid expansion vs expansion in January 2014. The outcome of interest was MILR (defined as video-assisted or robotic-assisted thoracoscopy) relative to open. Multivariable difference in differences (DID) cross-sectional analysis was used to estimate the average treatment effect (ATE) of Medicaid expansion. RESULTS: There were 41,439 patients who met inclusion criteria: 20,446 (49.3%) in expansion states and 20,993 (50.7%) in non-expansion states. Multivariable DID analysis showed that Medicaid expansion was associated with an increase in Medicaid insurance type with an ATE of 7.4% (95% CI 7.1-7.7%, P = .002). Medicaid expansion was also associated with increased MILR utilization in unadjusted analysis (10,278/20,446 (50.3%) vs 9,953/20,993 (47.4%), p < .001) and in multivariable DID analysis (ATE 0.6%, 95% CI 0.3-0.8%, P = .008). CONCLUSIONS: Although Medicaid expansion was associated with increased utilization of MILR for early stage lung cancer, the treatment effect was modest. This suggests that barriers in access to MILR are larger than simply access to care.

Are trauma surgical societies adequately addressing mental health after injury?

BACKGROUND: Survivors of physical trauma, their home caregivers, and their medical providers all have an increased risk of developing psychological distress and trauma-related psychiatric disease. The purpose of this study was to describe the frequency and change over time of trauma society research presentations regarding mental health to identify opportunities for growth. METHODS: Archives from 2018 to 2020 from the American Association for the Surgery of Trauma, the Eastern Association for the Surgery of Trauma, and the Western Trauma Association were reviewed. The studies that measured mental illness, psychosocial distress, and other psychosocial factors were assessed: for (1) the use of patient-reported outcome measures ; (2) the association of psychosocial variables with outcomes; and (3) the interventions investigated. Change over time was assessed using χ2 analysis. RESULTS: Of 1,239 abstracts, 57 (4.6%) addressed at least 1 mental health-related factor. Mental health was more frequently studied over time (2018 [3.2%]; 2019 [3.5%]; 2020 [7.7%]; P = .003). The most frequently measured factors were post-traumatic stress disorder, quality of life, general mental health, and depression. Seventeen (29.8%) abstracts addressed substance abuse, most commonly opioid abuse. Seven (12.3%) abstracts measured mental health in caregivers or medical providers. Patient-reported outcome measures were used in 32 studies (56.1%). Two-thirds of studies reported findings suggesting that mental illness impairs trauma-related outcomes. Only 5 (8.8%) investigated interventions designed to reduce adverse outcomes. CONCLUSION: Although academic discussion of mental health after trauma increased from 2018 to 2020, the topic remains a limited component of annual programs, patient-reported outcome measures remain underutilized, and intervention studies are rare.

Force characterization of intracranial endovascular embolization: coil type, microcatheter placement, and insertion rate.

BACKGROUND: Intraoperative rupture (IOR) is a rare, but potentially morbid complication of endovascular aneurysm coil embolization. Yet, IOR predictors have remained relatively uninvestigated in relation to coil design. OBJECTIVE: To develop a novel in vitro aneurysm model to characterize forces exerted by coils of different design on the aneurysm during endovascular embolization that are hypothesized to contribute to IOR. METHODS: A 3-mm saccular aneurysm model was developed with flat latex membrane at the dome apex. Membrane deflection was observed throughout simulated embolization and converted to force measurement. Simultaneous coil insertion and force measurement were accomplished with a compression strength-testing machine. Membrane and insertion forces across coil type, microcatheter tip placement, and insertion rate were evaluated. RESULTS: Insertion force and force directly on the aneurysm wall exhibited a difference, with framing coils exerting greatest force, followed by filling and finishing coils. Regarding microcatheter placement, a similar graded response in membrane and insertion forces was observed with positioning in the top-third of the aneurysm generating the greatest force compared with central and bottom-third placement. Insertion rate was also a factor with the slowest rate (10 mm/min) exhibiting the greatest membrane force, followed by lower forces at 30 and 50 mm/min. A multiple linear regression model was created to assess the contributions of each factor toward aneurysm forces. CONCLUSION: Increased force on the aneurysm is associated with framing coil use, microcatheter placement proximal to aneurysm dome, and slow insertion rate. Further characterization remains necessary to reduce IOR risk, especially concerning the contributions of insertion rate.
