RESUMEN
BACKGROUND: We examined outcomes in Acute Mesenteric Ischemia (AMI) with the hypothesis that Open Abdomen (OA) is associated with decreased mortality. METHODS: We performed a cohort study reviewing NSQIP emergency laparotomy patients, 2016-2020, with a postoperative diagnosis of mesenteric ischemia. OA was defined using flags for patients without fascial closure. Logistic regression was used with outcomes of 30-day mortality and several secondary outcomes. RESULTS: Out of 5514 cases, 4624 (83.9%) underwent resection and 387 (7.0%) underwent revascularization. The OA rate was 32.6%. 10.8% of patients who were closed required reoperation. After adjustment for demographics, transfer status, comorbidities, preoperative variables including creatinine, white blood cell count, and anemia, as well as operative time, OA was associated with OR 1.58 for mortality (95% CI [1.38, 1.81], p < 0.001). Among revascularizations, there was no such association (p = 0.528). OA was associated with ventilator support >48 h (OR 4.04, 95% CI [3.55, 4.62], and p < 0.001). CONCLUSION: OA in AMI was associated with increased mortality and prolonged ventilation. This is not so in revascularization patients, and 1 in 10 patients who underwent primary closure required reoperation. OA should be considered in specific cases of AMI. LEVEL OF EVIDENCE: Retrospective cohort, Level III.

OBJECTIVE: To determine the effect of operative versus nonoperative management of emergency general surgery conditions on short-term and long-term outcomes. BACKGROUND: Many emergency general surgery conditions can be managed either operatively or nonoperatively, but high-quality evidence to guide management decisions is scarce. METHODS: We included 507,677 Medicare patients treated for an emergency general surgery condition between July 1, 2015, and June 30, 2018. Operative management was compared with nonoperative management using a preference-based instrumental variable analysis and near-far matching to minimize selection bias and unmeasured confounding. Outcomes were mortality, complications, and readmissions. RESULTS: For hepatopancreaticobiliary conditions, operative management was associated with lower risk of mortality at 30 days [-2.6% (95% confidence interval: -4.0, -1.3)], 90 days [-4.7% (-6.50, -2.8)], and 180 days [-6.4% (-8.5, -4.2)]. Among 56,582 intestinal obstruction patients, operative management was associated with a higher risk of inpatient mortality [2.8% (0.7, 4.9)] but no significant difference thereafter. For upper gastrointestinal conditions, operative management was associated with a 9.7% higher risk of in-hospital mortality (6.4, 13.1), which increased over time. There was a 6.9% higher risk of inpatient mortality (3.6, 10.2) with operative management for colorectal conditions, which increased over time. For general abdominal conditions, operative management was associated with 12.2% increased risk of inpatient mortality (8.7, 15.8). This effect was attenuated at 30 days [8.5% (3.8, 13.2)] and nonsignificant thereafter. CONCLUSIONS: The effect of operative emergency general surgery management varied across conditions and over time. For colorectal and upper gastrointestinal conditions, outcomes are superior with nonoperative management, whereas surgery is favored for patients with hepatopancreaticobiliary conditions. For obstructions and general abdominal conditions, results were equivalent overall. These findings may support patients, clinicians, and families making these challenging decisions.

OBJECTIVE: To understand how multimorbidity impacts operative versus nonoperative management of emergency general surgery (EGS) conditions. BACKGROUND: EGS is a heterogenous field, encompassing operative and nonoperative treatment options. Decision-making is particularly complex for older patients with multimorbidity. METHODS: Using an instrumental variable approach with near-far matching, this national, retrospective observational cohort study of Medicare beneficiaries examines the conditional effects of multimorbidity, defined using qualifying comorbidity sets, on operative versus nonoperative management of EGS conditions. RESULTS: Of 507,667 patients with EGS conditions, 155,493 (30.6%) received an operation. Overall, 278,836 (54.9%) were multimorbid. After adjustment, multimorbidity significantly increased the risk of in-hospital mortality associated with operative management for general abdominal patients (+9.8%; P = 0.002) and upper gastrointestinal patients (+19.9%, P < 0.001) and the risk of 30-day mortality (+27.7%, P < 0.001) and nonroutine discharge (+21.8%, P = 0.007) associated with operative management for upper gastrointestinal patients. Regardless of multimorbidity status, operative management was associated with a higher risk of in-hospital mortality among colorectal patients (multimorbid: + 12%, P < 0.001; nonmultimorbid: +4%, P = 0.003), higher risk of nonroutine discharge among colorectal (multimorbid: +42.3%, P < 0.001; nonmultimorbid: +55.1%, P < 0.001) and intestinal obstruction patients (multimorbid: +14.6%, P = 0.001; nonmultimorbid: +14.8%, P = 0.001), and lower risk of nonroutine discharge (multimorbid: -11.5%, P < 0.001; nonmultimorbid: -11.9%, P < 0.001) and 30-day readmissions (multimorbid: -8.2%, P = 0.002; nonmultimorbid: -9.7%, P < 0.001) among hepatobiliary patients. CONCLUSIONS: The effects of multimorbidity on operative versus nonoperative management varied by EGS condition category. Physicians and patients should have honest conversations about the expected risks and benefits of treatment options, and future investigations should aim to understand the optimal management of multimorbid EGS patients.

INTRODUCTION: Many emergency general surgery (EGS) conditions can be managed both operatively or nonoperatively; however, it is unknown whether the decision to operate affects Black and White patients differentially. METHODS: We identified a nationwide cohort of Black and White Medicare beneficiaries, hospitalized for common EGS conditions from July 2015 to June 2018. Using near-far matching to adjust for measurable confounding and an instrumental variable analysis to control for selection bias associated with treatment assignment, we compare outcomes of operative and nonoperative management in a stratified population of Black and White patients. Outcomes included in-hospital mortality, 30-day mortality, nonroutine discharge, and 30-day readmissions. An interaction test based on a t test was used to determine the conditional effects of operative versus nonoperative management between Black and White patients. RESULTS: A total of 556,087 patients met inclusion criteria, of which 59,519 (10.7%) were Black and 496,568 (89.3%) were White. Overall, 165,932 (29.8%) patients had an operation and 390,155 (70.2%) were managed nonoperatively. Significant outcome differences were seen between operative and nonoperative management for some conditions; however, no significant differences were seen for the conditional effect of race on outcomes. CONCLUSIONS: The decision to manage an EGS patient operatively versus nonoperatively has varying effects on surgical outcomes. These effects vary by EGS condition. There were no significant conditional effects of race on the outcomes of operative versus nonoperative management among universally insured older adults hospitalized with EGS conditions.

INTRODUCTION: Prior studies have sought to describe Emergency General Surgery (EGS) burden, but a detailed description of resource utilization for both operative and nonoperative management of EGS conditions has not been undertaken. METHODS: Patient and hospital characteristics were extracted from Medicare data, 2015-2018. Operations, nonsurgical procedures, and other resources (i.e., radiology) were defined using Current Procedural Terminology codes. RESULTS: One million eight hundred two thousand five hundred forty-five patients were included in the cohort. The mean age was 74.7 y and the most common diagnoses were upper gastrointestinal. The majority of hospitals were metropolitan (75.1%). Therapeutic radiology services were available in 78.4% of hospitals and operating rooms or endoscopy suites were available in 92.5% of hospitals. There was variability in resource utilization across EGS subconditions, with hepatobiliary (26.4%) and obstruction (23.9%) patients most frequently undergoing operation. CONCLUSIONS: Treatment of EGS diseases in older adults involves several interventional resources. Changes in EGS models, acute care surgery training, and interhospital care coordination may be beneficial to the treatment of EGS patients.

INTRODUCTION: There is increasing emphasis on patient-reported outcomes (PROs) measures in healthcare, but this area remains largely unexplored in emergency general surgery (EGS) conditions. We hypothesized that postoperative patients in our EGS clinic would report detrimental changes in several domains of health-related quality of life (HRQoL). METHODS: We administered the PROMIS-29, a HRQoL measurement tool, to postoperative patients in our EGS clinic (11/2019-4/2020). Patients responded to measures of 7 domains. Domain scores were converted to t-scores, allowing comparison to average values within the general US population (set to 50 by definition). We report the mean scores within each domain. Higher scores in negatively worded domains (e.g., "Depression") are worse; vice versa for positively worded domains (e.g., "Physical Function"). Changes in scores at subsequent clinic visits were analyzed using the paired t-test. RESULTS: There were 97 patients who completed the PROMIS-29 at the first postoperative visit. Mean (SD) age was 54.1 (16.2) years; 51% were male. There was no difference in our patients from the average US population in the domains of Ability to Participate in Social Roles and Activities, Anxiety, Fatigue, and Sleep Disturbance. However, EGS patients experienced significantly greater Pain Interference (56.1 [54.1, 58.1]) and worse Physical Function (40.6 [38.4, 42.7]) than average. For patients seen in follow-up twice (13 patients, median interval between clinic visits 21 days), there were improvements in the domains of Physical Function (42.9 vs 37.3; p = 0.04) and Fatigue. CONCLUSION: We demonstrate room for improvement in the domains of pain interference and physical function. While positive changes over a relatively short period of time are encouraging, consideration should be given to patient perceptions of illness and lifestyle impact when managing EGS patients.

Little is known about the association between epidural catheters (EC) and venous thromboembolism (VTE) in trauma. We sought to study this association and hypothesized that trauma patients with EC were more likely to develop VTE. Using the Pennsylvania Trauma Outcomes Study (PTOS) registry, we identified all adult trauma patients (age ≥ 18) admitted for at least 2 days between 1/2013 and 12/2017. Baseline characteristics and outcome variables were compared between patients who underwent EC placement and those who did not. The primary outcome was development of VTE. 147,721 patients met inclusion criteria; 2247 (1.5%) developed a VTE. Patients were mostly white (85%), male (56%), with blunt trauma (94%). 776 (0.5%) had an EC placed. Patients who underwent EC placement were more likely to develop a VTE (2.8% vs. 1.5%, p = 0.003). After adjusting for covariates, patients with EC were 1.6 times more likely to develop VTE (95% CI 1.1-2.5). The overall rate of VTE was low and associated with the use of EC. Future work should focus on determining the underlying mechanisms.

BACKGROUND: Failure to rescue (FTR) refers to death after a major complication. Defining the optimal context in which to reduce FTR after injury requires knowledge of where and when FTR events occur. MATERIALS AND METHODS: Retrospective observational study of patients >16 y with a minimum Abbreviated Injury Score ≥2 at all 30 level I and II Pennsylvania trauma centers (2007-2015). Location and timing of the first major complication were collected. Complication, mortality, and FTR rates were calculated by location (prehospital, emergency department, operating room, stepdown unit, interventional radiology, intensive care unit (ICU), radiology, and the surgical ward) and by postadmission day. Kruskal-Wallis and chi-squared tests were used to compare variables. RESULTS: Major complications occurred in 15,388 of 178,602 (8.6%) patients. The median age was 58 y (interquartile range [IQR] 37-77 y), 78% were Caucasian, 68% were male, 89% were bluntly injured, and the median Injury Severity Score was 19 (IQR 10-29). Death occurred in 2512 of 15,388 patients with a major complication, for an FTR rate of 16.3%. Compared with non-FTR, FTR had earlier major complications (median day 2 [IQR 0-5 d] versus day 4 [IQR 2-8 d], P < 0.001). FTR rates were highest in the prehospital setting (42%), the operating room (33%), and the emergency department (32%), but the greatest number (1608 of 2512 total FTR events, 64%) occurred in the ICU. Pulmonary (32%) and cardiac (26%) complications most frequently contributed to FTR deaths. CONCLUSIONS: Interventions designed to reduce FTR after injury should focus on pulmonary and cardiac complications in the ICU.

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) has emerged as a bridge to definitive hemostasis in select patients with noncompressible torso hemorrhage. The number of patients who might benefit from this procedure, however, remains incompletely defined. We hypothesized that we could quantify the number of patients presenting to our center over a 2-year period who may have benefited from REBOA. METHODS: All patients presenting to our trauma center from 2014 to 2015 were included. Potential REBOA patients were identified based on anatomic injuries. We used ICD-9 codes to identify REBOA-amenable injury patterns and physiology. We excluded patients with injuries contraindicating REBOA. We then used chart review by two REBOA-experienced independent reviewers to assess each potential REBOA candidate, evaluate the accuracy of our algorithm, and to identify a cohort of confirmed REBOA candidates. RESULTS: Four thousand eight hundred eighteen patients were included of which 666 had injuries potentially amenable to REBOA. Three hundred thirty-five patients were hemodynamically unstable, and 309 patients had contraindications to REBOA. Sixty-four patients had both injury patterns and physiology amenable to REBOA with no contraindications, and these patients were identified as potential REBOA candidates. Of these, detailed independent two physician chart review identified 29 patients (45%) as confirmed REBOA candidates (interrater reliability kappa = 0.94, P < 0.001). CONCLUSIONS: Our database query identified patients with indications for REBOA but overestimated the number of REBOA candidates. To accurately quantify the REBOA candidate population at a given center, an algorithm to identify potential patients should be combined with chart review. STUDY TYPE: Therapeutic study, level V.

BACKGROUND: Training in Acute Care Surgery (ACS) is an integral component of general surgery residency and serves as a critical base experience for the added educational qualifications of fellowship. How this training varies between programs is not well characterized. We sought to describe the variation in clinical exposure between residencies in a sample of residents applying to an ACS fellowship. We hypothesized that applicants have significant variations in clinical exposure as well as unique and specific expectations for educational experiences. MATERIALS AND METHODS: We offered an anonymous 82-question survey focused on residency clinical exposure and self-perceived confidence in key areas of ACS training, as well as fellowship training and career expectations to all applicants interviewed at a single trauma, critical care, and emergency surgery fellowship program. Responses were assessed via absolute numbers and confidence via a 5-point Likert scale; data are reported using descriptive statistics and linear regression models. RESULTS: Forty-two interviewing applicants completed the survey, for a 96% response rate. Applicants reported heterogeneous levels of comfort across most ACS domains. There was good correlation between experience and comfort in most procedural areas. During fellowship training, respondents placed highest priority on operative experience, with 43% rating this as their highest priority, followed by penetrating trauma experience (33%). CONCLUSIONS: We found significant variations in both experience and comfort within key ACS domains among fellowship applicants. Despite training variability, there was good correlation between experience and self-reported comfort. Collaboration between residency and fellowship governing bodies may help address areas of limited exposure before entry into clinical practice.

BACKGROUND: The incidence of surgical site infection (SSI) has become a key quality indicator following clean and clean/contaminated surgical procedures. In contrast, contaminated and dirty wounds have garnered little attention with this quality metric because of the expected higher complication incidence. We hypothesized that wound management strategies in this high-risk population vary significantly and might not add value to the overall care. MATERIALS AND METHODS: This is a retrospective, observational study of trauma patients who underwent an exploratory laparotomy at an urban, academic, level 1 trauma center from 2014 to 2016. Deaths before hospital discharge were excluded. Wounds were classified using the Centers for Disease Control and Prevention definition on review of the operative reports. SSI was determined by review of the medical record, also per Centers for Disease Control and Prevention definition. Wound management strategies were categorized as either primary skin closure or closure by secondary intention. Outcomes were compared using Chi square or Kruskal-Wallis test. RESULTS: There were 128 patients who met study criteria. Fifty-five (42.9%) wounds were left open to close by secondary intention. In the wounds that were closed primarily (n = 73), eight (10.9%) developed an SSI. There were significant differences in the average length of stay (25.0 versus 11.6 d, P = 0.032), number of office visits (3.0 versus 1.8, P = 0.008), and time from last laparotomy to the last wound care office visit (112.8 versus 57.4, P = 0.012) between patients who were treated with secondary intention closure compared to those closed primarily who did not suffer from SSI. CONCLUSIONS: There is significant incidence of SSI in contaminated and dirty traumatic abdominal wounds; however, wound management strategies vary widely within this cohort. Closure by secondary intention requires significantly more resource utilization. Isolating risk factors for SSI may allow additional patients to undergo primary skin closure and avoid the morbidity of closure by secondary intention.

OBJECTIVE: We sought to determine whether state firearm legislation correlated with firearm-related fatality rates (FFR) during a 15-year period. BACKGROUND: The politicized and controversial topic of firearm legislation has been grossly understudied when the relative impact of American firearm violence is considered. Scientific evidence regarding gun legislation effectiveness remains scant. METHODS: Demographic and intent data (1999-2013) were collected from the Centers for Disease Control and Prevention's Web-Based Injury Statistics Query and Reporting System database and compared by state firearm legislation rankings with respect to FFR. State scorecards were obtained from firearm-restrictive (Brady Campaign/Law Center against Gun Violence [BC/LC]) and less-restrictive (National Rifle Association) groups. FFR were compared between restrictive and least-restrictive states during 3 periods (1999-2003, 2004-2008, 2009-2013). RESULTS: During 1999 to 2013, 462,043 Americans were killed by firearms. Overall FFR did not change during the 3 periods (10.89â±â3.99/100,000; 10.71â±â3.93/100,000; 11.14â±â3.91/100,000; P = 0.87). Within each period, least-restrictive states had greater unintentional, pediatric, and adult suicide, White and overall FFR than restrictive states (all P < 0.05). Conversely, no correlation was seen, during any of the 3 time periods, with either homicide or Black FFR-population subsets accounting for 41.7% of firearm deaths. CONCLUSIONS: Restrictive firearm legislation is associated with decreased pediatric, unintentional, suicide, and overall FFR, but homicide and Black FFR appear unaffected. Future funding and research should be directed at both identifying the most effective aspects of firearm legislation and creating legislation that equally protects every segment of the American population.

BACKGROUND: Aggressive management of patients prior to and after determination of death by neurologic criteria (DNC) is necessary to optimize organ recovery, transplantation, and increase the number of organs transplanted per donor (OTPD). The effects of time management are understudied but potentially pivotal component. The objective of this study was to analyze specific time points (time to DNC, time to procurement) and the time intervals between them to better characterize the optimal timeline of organ donation. METHODS: Using data over a 5-year time period (2011-2015) from the largest US OPO, all patients with catastrophic brain injury and donated transplantable organs were retrospectively reviewed. Active smokers were excluded. Maximum donor potential was seven organs (heart, lungs [2], kidneys [2], liver, and pancreas). Time from admission to declaration of DNC and donation was calculated. Mean time points stratified by specific organ procurement rates and overall OTPD were compared using unpaired t-test. RESULTS: Of 1719 Declaration of Death by Neurologic Criteria organ donors, 381 were secondary to head trauma. Smokers and organs recovered but not transplanted were excluded leaving 297 patients. Males comprised 78.8%, the mean age was 36.0 (±16.8) years, and 87.6% were treated at a trauma center. Higher donor potential (>4 OTPD) was associated with shorter average times from admission to brain death; 66.6 versus 82.2 hours, P = 0.04. Lung donors were also associated with shorter average times from admission to brain death; 61.6 versus 83.6 hours, P = 0.004. The time interval from DNC to donation varied minimally among groups and did not affect donation rates. CONCLUSIONS: A shorter time interval between admission and declaration of DNC was associated with increased OTPD, especially lungs. Further research to identify what role timing plays in the management of the potential organ donor and how that relates to donor management goals is needed.

BACKGROUND: Admission hypocalcemia predicts both massive transfusion and mortality in severely injured patients. However, the effect of calcium derangements during resuscitation remains unexplored. We hypothesize that any hypocalcemia or hypercalcemia (either primary or from overcorrection) in the first 24 hours after severe injury is associated with increased mortality. METHODS: All patients at our institution with massive transfusion protocol activation from January 2013 through December 2014 were identified. Patients transferred from another hospital, those not transfused, those with no ionized calcium (Ca) measured, and those who expired in the trauma bay were excluded. Hypocalcemia and hypercalcemia were defined as any level outside the normal range of Ca at our institution (1-1.25 mmol/L). Receiver operator curve analysis was also used to further examine significant thresholds for both hypocalcemia and hypercalcemia. Hospital mortality was compared between groups. Secondary outcomes included advanced cardiovascular life support, damage control surgery, ventilator days, and intensive care unit days. RESULTS: The massive transfusion protocol was activated for 77 patients of whom 36 were excluded leaving 41 for analysis. Hypocalcemia occurred in 35 (85%) patients and hypercalcemia occurred in 9 (22%). Mortality was no different in hypocalcemia versus no hypocalcemia (29% vs 0%; P = .13) but was greater in hypercalcemia versus no hypercalcemia (78% vs 9%; P < .01). Receiver operator curve analysis identified inflection points in mortality outside a Ca range of 0.84 to 1.30 mmol/L. Using these extreme values, 15 (37%) had hypocalcemia with a 60% mortality (vs 4%; P < .01) and 9 (22%) had hypercalcemia with a 78% mortality (vs 9%; P < .01). Patients with extreme hypocalcemia and hypercalcemia also received more red blood cells, plasma, platelets, and calcium repletion. CONCLUSIONS: Hypocalcemia and hypercalcemia occur commonly during the initial resuscitation of severely injured patients. Mild hypocalcemia may be tolerable, but more extreme hypocalcemia and any hypercalcemia should be avoided. Further assessment to define best practice for calcium management during resuscitation is warranted.

BACKGROUND: Police transport (PT) of penetrating trauma patients has the potential to decrease prehospital times for patients with life-threatening hemorrhage and is part of official policy in Philadelphia, Pennsylvania. We hypothesized that rates of PT of bluntly injured patients have increased over the past decade. METHODS: We used Pennsylvania Trauma Outcomes Study registry data from 2006-15 to identify bluntly injured adult patients transported to all 8 trauma centers in Philadelphia. PT was compared to ambulance transport, excluding transfers, burn patients, and private transport. We compared demographics, mechanism, and injury outcomes between PT and ambulance transport patients and used multivariable logistic regression to identify independent predictors of PT. We also identified physiological indicators and injury patterns that might have benefitted from prehospital intervention by EMS. RESULTS: Of 28 897 bluntly injured patients, 339 (1.2%) were transported by police and 28 558 (98.8%) by ambulance. Blunt trauma accounted for 11% of PT and penetrating trauma for 89%. PT patients were younger, more likely to be male, and more likely to be African American or Asian and were more often injured by assault or motor vehicle crash. There were no significant differences presenting physiology between PT and EMS patients. In multivariable logistic regression analysis, male sex (OR 1.89, 95%CI 1.40-2.55), African American race (OR 1.71 95%CI 1.34-2.18), and Asian race (OR 2.25, 95%CI 1.22-4.14) were independently associated with PT. Controlling for injury severity and physiology, there was no significant difference in mortality between PT and EMS. Overall, 64% of PT patients had a condition that might have benefited from prehospital intervention such as supplemental oxygen for brain injury or spine stabilization for vertebral fractures. CONCLUSIONS: PT affects a small minority of blunt trauma patients, and did not appear associated with higher mortality. However, PT patients included many who might have benefited from proven, prehospital intervention. Clinicians, EMS providers, and law enforcement should collaborate to optimize use of PT within the trauma system.

BACKGROUND: Although trauma patients are frequently cared for in the intensive care unit (ICU), admission triage criteria are unclear and may vary among providers and institutions. The benefits of close monitoring must be weighed against the economic and opportunity costs of an ICU admission. MATERIALS AND METHODS: We conducted a retrospective cohort study of patients treated for blunt splenic injuries from 2011-2014 at 30 level I and II Pennsylvania trauma centers. We used multivariable logistic regression to assess the relationship between ICU admission and mortality, adjusting for patient characteristics, injury characteristics, and physiology. We calculated center-level observed-to-expected ratios for ICU utilization and mortality and evaluated correlations with Spearman's rho. We compared the proportion of patients receiving critical care procedures, such as mechanical ventilation or central line placement between high and low-ICU-utilization centers. RESULTS: Of 2587 patients with blunt splenic injuries, 63.9% (1654) were admitted to the ICU. Median injury severity score was 17 overall, 13 for non-ICU patients and 17 for ICU patients (P < 0.001). In multivariable logistic regression, ICU admission was not significantly associated with mortality. Center-level risk-adjusted ICU admission rates ranged from 17.9%-87.3%. Risk-adjusted mortality rates ranged from 1.2%-9.6%. There was no correlation between observed-to-expected ratios for ICU utilization and mortality (Spearman's rho = -0.2595, P = 0.2103). Proportionately fewer ICU patients received critical care procedures at high-utilization centers than at low-utilization centers. CONCLUSIONS: Risk-adjusted ICU utilization rates for splenic trauma varied widely among trauma centers, with no clear relationship to mortality. Standardizing ICU admission criteria could improve resource utilization without increasing mortality.

BACKGROUND: Failure to rescue (FTR: the conditional probability of death after complication) has been studied in trauma cohorts, but the impact of age and preexisting conditions (PECs) on risk of FTR is not well known. We assessed the relationship between age and PECs on the risk of experiencing serious adverse events (SAEs) subsequent FTR in trauma patients with the hypothesis that increased comorbidity burden and age would be associated with increased FTR. MATERIALS AND METHODS: We performed a retrospective cohort analysis at an urban level 1 trauma center in Pennsylvania. All patients aged ≥16 y with minimum Abbreviated Injury Scale score ≥2 from 2009 to 2013 were included. Univariate logistic regression models for SAE and FTR were developed using age, PECs, demographics, and injury physiology. Variables found to be associated with the end point of interest (P ≤ 0.2) in univariate analysis were included in separate multivariable logistic regression models for each outcome. RESULTS: SAE occurred in 1136 of 7533 (15.1 %) patients meeting inclusion criteria (median age 42 [interquartile range 26-59], 53% African-American, 72% male, 79% blunt, median ISS 10 [interquartile range 5-17]). Of those who experienced an SAE, 129 of 1136 patients subsequently died (FTR = 11.4%). Development of SAE and FTR was associated with age ≥ 70 y (odds ratio 1.58-1.78, 95% confidence interval 1.13-2.82). Renal disease was the only preexisting condition associated with both SAE and FTR. CONCLUSIONS: Trauma patients with renal disease are mostly at increased risk for both SAE and FTR, but other PECs associated with SAE are not necessarily those associated with FTR. Future interventions designed to reduce FTR events should target this high-risk cohort.

Advanced practitioners (APs) have been successfully integrated into the clinical care of injured patients. Given the expanding role of APs in trauma care, we hypothesized that APs can perform Performance Improvement and Patient Safety (PIPS) peer review at a level comparable with trauma surgeons. For Phase 1, cases previously reviewed by a trauma surgeon were randomly selected by the PIPS coordinator and peer reviewed by an AP. The trauma surgeons' and APs' reviews were compared. For Phase 2, cases requiring concurrent review were peer reviewed by both an AP and an MD, who were blinded to each other's review. Both the APs' and trauma surgeons' reviews of the same medical record were presented at a bimonthly performance improvement (PI) meeting. In Phase 1, 46 PI cases were reviewed including 22 deaths. Trauma surgeons and APs had high concordance (96.0%) regarding appropriateness or inappropriateness of care (κ = 0.774). Among disagreements, APs were 3 times more likely than trauma surgeons to determine care to be inappropriate. Trauma surgeons and APs had similarly high concordance (95.5%) regarding preventability of mortality (κ = 0.861). In Phase 2, 38 PI cases were reviewed, including 31 deaths. Trauma surgeons and APs had high concordance (89.0%) regarding appropriateness or inappropriateness of care (κ = 0.585). Among disagreements, trauma surgeons and APs had similarly high concordance (86.2%) regarding preventability of mortality (κ = 0.266). We found that APs had high concordance with trauma surgeons regarding medical record reviews and are thus able to effectively review medical records for the purposes of PIPS.

Background: Although timely access to trauma center (TC) care for injured patients is essential, the proliferation of new TCs does not always improve outcomes. Hospitals may seek TC accreditation for financial reasons, rather than to address community or geographic need. Introducing new TCs risks degrading case and payer mix at established TCs. We hypothesized that newly accredited TCs would see a disproportionate share of commercially insured patients. Study design: We collected data from all accredited adult TCs in Pennsylvania using the state trauma registry from 1999 to 2018. As state policy regarding supplemental reimbursement for underinsured patients changed in 2004, we compared patient characteristics and payer mix between TCs established before and after 2004. We used multivariable logistic regression to assess the relationship between payer and presentation to a new versus established TC in recent years. Results: Over time, there was a 40% increase in the number of TCs from 23 to 38. Of 326 204 patients from 2010 to 2018, a total of 43 621 (13.4%) were treated at 15 new TCs. New TCs treated more blunt trauma and less severely injured patients (p<0.001). In multivariable analysis, patients presenting to new TCs were more likely to have Medicare (OR 2.0, 95% CI 1.9 to 2.1) and commercial insurance (OR 1.6, 95% CI 1.5 to 1.6) compared with Medicaid. Over time, fewer patients at established TCs and more patients at new TCs had private insurance. Conclusions: With the opening of new centers, payer mix changed unfavorably at established TCs. Trauma system development should consider community and regional needs, as well as impact on existing centers to ensure financial sustainability of TCs caring for vulnerable patients. Level of evidence: Level III, prognostic/epidemiological.
RESUMEN
Objective: This study investigates the challenge posed by state borders by identifying the population, injury, and geographic scope of areas of the country where the closest trauma center is out-of-state, and by collating state emergency medical services (EMS) policies relevant to cross-border trauma transport. Methods: We identified designated levels I, II, and III trauma centers using data from American Trauma Society. ArcGIS was used to map the distance between US census block groups and trauma centers to identify the geographic areas for which cross-border transport may be most expedient. National Highway Traffic Safety Administration data were queried to quantify the proportion of fatal crashes occurring in the areas of interest. State EMS protocols were categorized by stance on cross-border transport. Results: Of 237 596 included US census block groups, 18 499 (7.8%) were closest to an out-of-state designated level I or II trauma center. These census block groups accounted for 6.9% of the US population and 9.5% of all motor vehicle fatalities. With the inclusion of level III trauma centers, the number of US census block groups closest to an out-of-state designated level I, II, or III trauma center decreased to 13 690 (5.8%). These census block groups accounted for 5.1% of the US population and 7.1% of all motor vehicle fatalities. Of the 48 contiguous states, 30 encourage cross-border transport, 2 discourage it, 12 are neutral, and 4 leave it to local discretion. Conclusion: Cross-border transport can expedite access to care in at least 5% of US census block groups. While few states discourage this practice, more robust policy guidance could reduce delays and enhance care. Level of Evidence: III, Epidemiological.
