Consensus-based Standards and Indicators to strengthen trauma center injury and violence prevention programs.

For decades, the American College of Surgeons Committee on Trauma (ACSCOT) has published Resources for Optimal Care of the Injured Patient, which outlines specific criteria necessary to be verified by the college as a trauma center, including having an organized and effective approach to prevention of trauma. However, the document provides little public health-specific guidance to assist trauma centers with developing these approaches. An advisory panel was convened in 2017 with representatives from national trauma and public health organizations with the purpose of identifying strategies to support trauma centers in the development of a public health approach to injury and violence prevention and to better integrate these efforts with those of local and state public health departments. This panel developed the Standards and Indicators for Model Level I and II Trauma Center Injury and Violence Prevention Programs. The document outlines five, consensus-based core components of a model injury and violence prevention program: (1) leadership, (2) resources, (3) data, (4) effective interventions, and (5) partnerships. We think this document provides the missing public health guidance and is an essential resource to trauma centers for effectively addressing injury and violence in our communities. We recommend the Standards and Indicators be referenced in the injury prevention chapter of the upcoming revision of ACSCOT's Resources for Optimal Care of the Injured Patient as guidance for the development, implementation and evaluation of injury prevention programs and be used as a framework for program presentation during ACSCOT verification visits.

A Case Review Series of Christiana Care Health System's Experience with Negative Pressure Wound Therapy Instillation.

Acute and chronic wounds afflict a multitude of patients to varying degrees. Wound care treatment modalities span the spectrum of technological advancement and with that differ greatly in cost. Negative pressure wound therapy (NPWT) can now be combined with instillation and dwell time (NPWTi-d). This case review series of 11 patients in a community hospital setting provides support for the utilization of NPWTi-d. Additionally, current literature on the use of NPWTi-d in comparison to NPWT will be reviewed.  We highlight three specific cases. The first case is a 16-year-old male who was shot in the left leg. He suffered a pseudoaneurysm and resultant compartment syndrome. This required a fasciotomy and delayed primary closure. To facilitate this, NPWTi-d was employed and resulted in a total of four operative procedures before closure 13 days after admission. Next, a 61-year-old uncontrolled diabetic female presented with necrotizing fasciitis of the lower abdomen and pelvis. She underwent extensive debridement and placement of NPWTi-d with Dakin's solution. A total of four operative procedures were performed including delayed primary closure six days after admission. Finally, a 48-year-old female suffered a crush injury with internal degloving. NPWTi-d with saline was utilized until discharge home on postoperative day 12. NPWTi-d, when compared to NPWT, has been reported to lead to a decrease in time to operative closure, hospital length of stay, as well as operative procedures required. The cost-benefit analysis in one retrospective review noted a $1,400 savings when these factors were taken into account. This mode of wound care therapy has significant benefits that warrant the development of a prospective randomized controlled trial to further define the improvement in quality-of-life provided to the patient and the reduction of potential overall healthcare costs.

Longitudinal assessment of injury recidivism among adults in the United States: findings from a population-based sample.

BACKGROUND: Repeated injuries, as known as injury recidivism, pose a significant burden on population health and healthcare settings. Therefore, identifying those at risk of recidivism can highlight targeted populations for primary prevention in order to improve health and reduce healthcare expenditures. There has been limited research on factors associated with recidivism in the U.S. Using a population-based sample, we aim to: 1) identify the prevalence and risk factors for injury recidivism among non-institutionalized adults; 2) investigate the trend in nationwide recidivism rates over time. METHODS: Using the Medical Expenditure Panel Survey (MEPS), 19,134 adults with at least one reported injury were followed for about 2 years. Reported injuries were those associated with healthcare utilization, disability days or any effects on self-reported health. The independent associations between risk factors for recidivism were evaluated incorporating a weighted logistic regression model. RESULTS: There were 4,136 recidivists representing over nine million individuals in the U.S. over a 2-year follow-up. About 44 % of recidivists sustained severe injuries requiring a hospitalization, a physician's office visit or an emergency department visit. Compared with those who sustained a single injury, recidivists were more likely to be white, unmarried, reside in metropolitan areas, and report a higher prevalence of chronic conditions. Age, sex, race/ethnicity, marital status, urbanicity, region, diabetes, stroke, asthma and depression symptoms were significant predictors of recidivism. Significant interaction effects between age and gender suggested those in the 18-25 age group, the odds of being a recidivist were 1.45 higher among males than females adjusting for other covariates. While having positive screens for depression in both follow-up years was associated with 1.46 (95 % CI = 1.21-1.77) higher odds of recidivisms than the reference group adjusting for other variables. CONCLUSIONS: We observed a higher recidivism rate among injured individuals in this study than previously reported. Our findings emphasize the pressing need for injury prevention to reduce the burden of repeated injuries. Preventative efforts may benefit from focusing on males between 18 and 25 years of age and those with comorbidities such as diabetes, stroke and depression.

Using simulation for disaster preparedness.

BACKGROUND: As it addresses both technical and nontechnical skills, simulation-based training is playing an increasingly important role in surgery. In addition to the focus on skill acquisition, it is also important to ensure that surgeons are able to perform a variety of tasks in unique and challenging situations. These situations include responding to mass casualties, dealing with disease outbreaks, and preparing for wartime missions. Simulation-based training can be a valuable training modality in these situations, as it allows opportunities to practice and prepare for high-risk and often low-frequency events. METHODS: During the 8th Annual Meeting of the Consortium of the American College of Surgeons-Accredited Education Institutes in March 2015, a multidisciplinary panel was assembled to discuss how simulation can be used to prepare the surgical community for such high-risk events. CONCLUSION: An overview of how simulation has been used to address needs in each of these situations is presented.

Embedding a trauma hospitalist in the trauma service reduces mortality and 30-day trauma-related readmissions.

BACKGROUND: Recognizing the increasing age and comorbid conditions of patients admitted to our trauma service, we embedded a hospitalist on the trauma service at our Level I trauma center.This program was initiated in January 2013. This study was designed to investigate differences in outcomes between trauma patients who received care from the trauma hospitalist (THOSP) program and similarly medically complex trauma patients who did not receive THOSP care. METHODS: There were 566 patients comanaged with THOSP between December 2013 and November 2014. These patients were matched (1:2) with propensity scores to a contemporaneous control group based on age, Injury Severity Score (ISS), and comorbid conditions. Outcomes examined included mortality, trauma-related readmissions, upgrades to the intensive care unit, hospital length of stay, the development of in-hospital complications, and the frequency of obtaining medical subspecialist consultation. Differences in outcomes were compared with Mann-Whitney U-test or χ test as appropriate. RESULTS: High-quality matching resulted in the loss of 97 THOSP patients for the final analysis. Table 1 shows the balance between the two groups after matching. While there was a 1-day increase in hospital length of stay and an increase in upgrades to the intensive care unit, there was a reduction in mortality, trauma-related readmissions, and the development of renal failure after implementation of the THOSP program (Table 2). Implementation of this program made no significant difference in the frequency of cardiology, nephrology, neurology, or endocrinology consultations. There was also no difference in the development of the complications of venous thromboembolism, pneumonia, stroke, urinary tract infection, bacteremia, or alcohol withdrawal. CONCLUSION: Our study provides evidence that embedding a hospitalist on the trauma service reduces mortality and trauma-related readmissions. A reason for these improved outcomes may be related to THOSP "vigilance." LEVEL OF EVIDENCE: Therapeutic/care management study, level IV.

The pediatric trauma center and the inclusive trauma system: Impact on splenectomy rates.

BACKGROUND: Before 2006, the Delaware Trauma System (DTS) did not include a designated pediatric trauma center (PTC). In 2006, the Delaware Trauma System designated and the American College of Surgeons Committee on Trauma verification/consultation program verified Nemours AI DuPont Hospital for Children, a freestanding children's hospital, as a PTC. We evaluated the impact of the addition of the PTC to the state trauma system on pediatric traumatic splenectomy rates. METHODS: The study cohort comprised DTS trauma registry recorded children younger than 16 years with spleen injury (ICD-9 codes 865.0-865.9) from January 1998 through December 2012. This cohort was categorized into pre-PTC (1998-2005) and post-PTC (2006-2012) groups. Penetrating injuries were excluded. Comparisons between groups included age, gender, length of stay, organ-specific injury grade, Injury Severity Score, incidence of polytrauma, splenectomy rate, and admitting hospital. Management, operative versus nonoperative, of low grade (Organ Injury Scale [OIS] score, 1-3) and high grade (OIS score, 4-5) were also compared. Pearson's χ analysis was performed for categorical variables. Continuous variables were reported as mean (standard deviation) and compared by Student's t test for independent normally distributed samples. Mann-Whitney U-test was used for non-normally distributed variables. A value of p < 0.05 was considered significant. RESULTS: Of the 231 pediatric spleen injuries, 118 occurred pre-PTC and 113 occurred post-PTC. There were no significant differences in age, gender, length of stay, Injury Severity Score, OIS grade, or incidence of polytrauma. Splenectomy rates decreased from 11% (13 of 118) pre-PTC to 2.7% (3 of 113) post-PTC (p = 0.012). CONCLUSION: The addition of an American College of Surgeons-verified PTC within an inclusive trauma system that was previously without one was associated with a significant reduction in the rate of blunt trauma-related splenectomy. Integration of a verified PTC is an influential factor in achieving spleen preservation rates equivalent to published American Pediatric Surgery Association benchmarks within a trauma system. LEVEL OF EVIDENCE: Therapeutic study, level IV; epidemiologic study, level III.

Long-term outcome in elderly patients after operation for traumatic intracranial hemorrhage.

OBJECTIVE: This study examined outcomes in elderly TBI patients who underwent a cranial operation. METHODS: We identified TBI patients > or = 65 who underwent a cranial operation from January 1, 2004 to December 31, 2008. Data collected included: age, admission GCS, mechanism of injury, ISS, Head AIS, type of operation, hemorrhage acuity, time to operation, pre-hospital warfarin or clopidogrel, and in-hospital death. Survivors were contacted by phone to determine an Extended Glasgow Outcome Score (GOSE). A favorable outcome was defined as having a GOSE of > or = 5 at follow-up, an unfavorable outcome was defined as: in-hospital death, death within one year of injury, and a GOSE < 5 at follow-up. Chi-square and student's t-test were used. RESULTS: One hundred sixty-four elderly TBI patients underwent cranial surgery. Mean age was 79.2 +/- 7.6 years. Most patients: had a ground level fall (86.0%), suffered a subdural hematoma (95.1%), and underwent craniotomy (89.0%). Twenty-eight percent died in the hospital and another 20.1% died within one year. Fifty-six patients were eligible for a GOSE interview of these: 17 were lost to follow-up, seven refused the GOSE interview, 22 had a GOSE > or = 5, and ten had a GOSE < 5. Mean follow-up was 42.6 +/- 14.9 months. Of all the factors analyzed, only older age was associated with an unfavorable outcome. CONCLUSIONS: While age was associated with outcome, we were unable to demonstrate any other early factors that were associated with long-term functional outcome in elderly patients that underwent a cranial operation for TBI.

Delaware's inclusive trauma system: impact on mortality.

BACKGROUND: The impact of implementing an inclusive state trauma system on injury-related mortality for patients with life-threatening injuries was assessed. METHODS: Using the state trauma registry, trauma patients evaluated in all of Delaware's acute care hospitals from 1998 to 2007 were identified. Patients were categorized by injury severity score (ISS) groups (1-9, 10-15, 16-24, and >24). Each category was analyzed by mortality and interfacility transfer rate to the Level I trauma center for each year. An analysis of the National Trauma Data Bank (NTDB) for these ISS groups and mortality was performed to provide a comparative benchmark. Chi(2) and analysis of variance were used where appropriate (p 24 group. For this group, there was an incremental mortality decrease from 45.7% (1998) to 20.5% (2007) (p 24 group managed at the Level I hospital significantly increased over the same period. CONCLUSION: Since its inception, Delaware's trauma system, in which all acute care hospitals participate, has been associated with an incremental, significant decrease in mortality of the most critically injured patients. This decrease is more substantial than that experienced nationally as depicted within the NTDB. These findings and our evolving experience support the concept and benefits of an "inclusive" trauma system.

Effect of a graduated licensing system on motor vehicle crashes and associated injuries involving drivers less than 18 years-of-age.

OBJECTIVES: The rate of motor vehicle crashes in the United States is higher among adolescent drivers than among any other age group. This study was conducted to determine whether implementation of a graduated driver's licensing program is associated with a reduced the rate of motor vehicle crashes and injuries involving adolescent driver. METHODS: Time periods before and after establishment of Delaware's GDL program were compared. The one year "before" period spanned January 1, 1998, through December 31, 1998, and the 3-year "after" period spanned January 1, 2000, to December 31, 2002. Following enactment of the GDL program on July 1, 1999, we delayed data collection during the "after" period for 6 months to allow for full implementation of the program. Information was obtained for all Delaware registered drivers between ages 16 and 17 years were involved in motor vehicle crashes involving property damage or injury from 1998 to 2002. The rate of crashes involving property damage, EMS transport, injury, hospitalization, and death were determined pre- and post-GDL,. Length of hospitalization and hospital charges were compared, and the presence and age of passengers, along with time of day were determined. RESULTS: The total number of licensed 16- and 17-year-old drivers in Delaware was 14,320 during 1998 (the before period), 16,849 for 2000, 14,098 for 2001, and 14,276 for 2002, for a total of 45,223 licensed drivers studied during the after period. The proportion of hospitalizations, injuries, crashes involving property damage and total number of crashes involving registered 16- and 17-year-old drivers after GDL each decreased by at least 30%. In addition, this GDL program was associated with a reduction in nighttime crashes and in crashes involving cars with multiple passengers in comparison with the time period before GDL. CONCLUSIONS: Two years after implementation, the hospitalization rate, injury rate, and crash rate decreased significantly with enactment of the GDL program in the State of Delaware. The Delaware's GDL program appears successful in decreasing motor vehicle crashes and resultant injuries in adolescent drivers.

The Delaware trauma system: impact of Level III trauma centers.

BACKGROUND: In 2000, Delaware instituted a trauma system that included establishing four Level III trauma centers in counties previously without trauma centers. The purpose of this study was to analyze whether implementation of this inclusive trauma system reduced the injury-related mortality rates in these counties. METHODS: Using the state trauma registry, patients with trauma admitted to all acute care hospitals in Delaware from January 1, 1995 through December 31, 2004 were identified and categorized into two groups: preimplementation of an inclusive trauma system (1995-1999), and postimplementation (2000-2004). These groups were compared in aggregate and by individual counties for age, sex, mechanism of injury, Abbreviated Injury Score, injury-related mortality rate, mean Injury Severity Score (ISS), acute transfers out, and acute transfers in (Level I only). chi test and Mann-Whitney U test were used where indicated. Significance was determined to be p < or = 0.05. RESULTS: After implementation, mortality rates significantly decreased (5.3%-2.8%) and rate of acute transfers out increased (14.7%-19.5%) in the counties served by the Level III centers. The ISS of patients in the Level I trauma center significantly increased (mean ISS = 10) when compared with the Level III trauma centers (mean ISS = 6), reflecting increased transfers of patients with severe injuries. CONCLUSION: An inclusive state trauma system that included the establishment of Level III trauma centers in previously underserved counties led to a decrease in trauma-related mortality rates in these counties. In the county served by the Level I trauma center, mortality remained unchanged despite an increase in admissions and the injury severity of these admissions.

Admission hyperglycemia as a prognostic indicator in trauma.

OBJECTIVE: The purpose of this study was to assess the utility of two levels of hyperglycemia as predictors for mortality and infectious morbidity in traumatically injured patients. METHODS: All patients >or= 17 years old presenting to a Level I trauma center as a "trauma alert" or a "trauma code" from January 1, 2000, through December 31, 2000, were reviewed. Hypoglycemic patients (glucose concentration < 70 mg/dL) were excluded (n = 4). Patients were considered hyperglycemic with an admission glucose concentration > 200 mg/dL (moderate hyperglycemia) or an admission glucose concentration in the upper quartile for the group (mild hyperglycemia [glucose concentration > 135 mg/dL]). RESULTS: Seven hundred thirty-eight patients were included in the study. Hyperglycemia was associated with increased mortality among both patients with moderate hyperglycemia (34.1% vs. 3.7%, p < 0.01) and those with mild hyperglycemia (15.5% vs. 2%, p < 0.01) compared with corresponding normoglycemic groups. Hyperglycemia proved to be an independent predictor of mortality and of hospital and intensive care unit length of stay after multiple logistic regression while controlling for age, Injury Severity Score, Revised Trauma Score, and gender. Infectious complications, including pneumonia (9.4% vs. 2%, p = 0.001), urinary tract infections (6.6% vs. 1.4%, p = 0.001), wound infections (4.9% vs. 0.6%, p = 0.039), and bacteremia (5% vs. 1.1%, p = 0.004), were significantly increased in patients with elevated glucose concentrations. Hyperglycemia is an independent predictor of increased infectious morbidity controlling for age, gender, and Injury Severity Score in multiple logistic regression models. CONCLUSION: Hyperglycemia independently predicts increased intensive care unit and hospital length of stay and mortality in the trauma population. It is associated with increased infectious morbidity. These associations hold true for mild hyperglycemia (glucose concentration > 135 mg/dL) and moderate hyperglycemia (glucose concentration > 200 mg/dL).

In-house trauma surgeons do not decrease mortality in a level I trauma center.

BACKGROUND: The value of an in-house trauma surgeon is debated. Previous studies focus on comparing in-house and on-call surgeons at different institutions or different periods in time. The purpose of this study was to simultaneously evaluate in-house and on-call trauma surgeons in a single Level I trauma center and to determine the impact of in-house trauma surgeons on the mortality of severely injured patients. METHODS: All records were reviewed for patients classified as major resuscitations from July 1997 through November 1999. Multiple logistic regression was performed to determine predictors of mortality on the basis of trauma surgeon status (in-house vs. on-call) and response time, while controlling for Injury Severity Score (ISS) and Revised Trauma Score. RESULTS: Of the 4,278 admissions, 537 were trauma codes. Mean ISS was 20.16 +/- 11.59. There was no difference between groups admitted by in-house surgeons versus on-call surgeons with respect to ISS or Revised Trauma Score. Mortality for the group was 24.8% (133 of 537); no statistical difference existed between observed and expected mortality by TRISS. The average response time was 3.96 minutes for the in-house group and 14.70 minutes for the on-call group (p < 0.001). Neither the call status nor the response time of the trauma surgeon significantly decreased emergency department or hospital mortality. There was a trend for improved outcome in those patients cared for by an in-house surgeon who were upgraded to a code, transferred into the institution, admitted during the night, or neurologically impaired. This trend did not reach statistical significance. CONCLUSION: When the trauma surgeon was rapidly available (< 15 minutes), there was no difference in emergency department or hospital mortality between in-house and on-call trauma surgeons. Selected subgroups of severely injured patients may benefit from an in-house trauma surgeon. If trauma surgeons are not readily available in an institution, an in-house call policy may be necessary for the prompt resuscitation of critically ill patients.

Validation of new trauma triage rules for trauma attending response to the emergency department.

INTRODUCTION: The American College of Surgeons Committee on Trauma has suggested triage criteria for the immediate attendance of a trauma surgeon to an injured patient in the emergency department. This study validates the accuracy of these criteria in identifying high-risk trauma patients and assesses the impact of trauma surgeon response time. METHODS: A study group of trauma patients with a systolic blood pressure (SBP) < 90 mm Hg, Glasgow Coma Scale (GCS) score < 8, airway compromise managed with endotracheal intubation (ETI) or surgical airway, or gunshot wound (GSW) to the neck or torso were compared with a control group of patients meeting none of these criteria. Outcome measurements included Injury Severity Score (ISS), duration of hospitalization (length of stay [LOS]), intensive care unit (ICU) days, direct transfer to the ICU or operating room, and mortality. For the study group, trauma surgeon response times, < or = 15 minutes and > 15 minutes, were compared for age, ISS, LOS, ICU days, mortality, and direct transfer to the ICU or operating room. Statistical analysis was performed using the t test and the Yates-corrected chi(2) test (p < 0.05), with odds ratios calculated on the basis of trauma activation criteria and outcome measures. Multiple logistic regression was used to assess the relation between the independent variables SBP, GCS, ETI, and GSW with direct transfer to the ICU or operating room and mortality. RESULTS: A total of 4,910 patients were identified, including 791 study group patients. The mean ISS, LOS, ICU days, and mortality were significantly higher in the study group (p < 0.01). Odds ratios of the study group for direct transfer to the ICU or operating room were 91 and 2 for ETI, 23 and 1.4 for GCS score < 8, 8 and 2.2 for GSW, and 7 and 1.6 for SBP < 90 mm Hg, respectively. The odds ratios for mortality were 39 for ETI, 104 for GCS score < 8, 12 for GSW, and 74 for SBP < 90 mm Hg. Regression analysis demonstrated that GSW, SBP < 90 mm Hg, and ETI predicted ICU admission; GSW, SBP < 90 mm Hg, and ETI predicted operative intervention; and GCS score < 8, SBP < 90 mm Hg, and ETI were associated with mortality. Trauma surgeon response times were available for 658 (83%) of the study group patients. No significant differences were found between the two response groups. CONCLUSION: Trauma patients meeting the triage criteria proposed by the American College of Surgeons Committee on Trauma have more severe injuries, a higher mortality rate, and longer hospital and ICU stays than control patients. SBP < 90 mm Hg, ETI, and GSW are predictive of urgent operating room use and ICU admission. A significantly higher mortality rate is associated with SBP < 90 mm Hg, ETI, and GCS score < 8. Incorporating these criteria into trauma center triage rules to identify high-risk injured patients is warranted. However, trauma surgeon response time < or = 15 minutes was not associated with improved patient outcome, and optimal response time remains uncertain.
