The burden of geriatric traumatic brain injury on trauma systems: Analysis of 348,800 Medicare inpatient claims.

BACKGROUND: Traumatic brain injury (TBI) is a leading cause of death and disability in older adults. The aim of this study was to characterize the burden of TBI in older adults by describing demographics, care location, diagnoses, outcomes, and payments in this high-risk group. METHODS: Using 2016-2019 Centers for Medicare & Medicaid Services (CMS) Inpatient Standard Analytical Files (IPSAF), patients >65 years with TBI (>1 injury ICD-10 starting with "S06") were selected. Trauma center levels were linked to the IPSAF file via American Hospital Association Hospital Provider ID and fuzzy-string matching. Patient variables were compared across trauma center levels. RESULTS: Three hundred forty-eight thousand eight hundred inpatients (50.4% female; 87.1% white) from 2963 US hospitals were included. Level I/II trauma centers treated 66.9% of patients; non-trauma centers treated 21.5%. Overall inter-facility transfer rate was 19.2%; in Level I/II trauma centers transfers-in represented 23.3% of admissions. Significant TBI (Head AIS ≥3) was present in 70.0%. Most frequent diagnoses were subdural hemorrhage (56.6%) and subarachnoid hemorrhage (30.6%). Neurosurgical operations were performed in 10.9% of patients and operative rates were similar regardless of center level. Total unadjusted mortality for the sample was 13.9%, with a mortality of 8.1% for those who expired in-hospital, and an additional 5.8% for those discharged to hospice. Medicare payments totaled $4.91B, with the majority (73.4%) going to Level I/II trauma centers. CONCLUSIONS: This study fills a gap in TBI research by demonstrating that although the majority of older adult TBI patients in the United States receive care at Level I/II trauma centers, a substantial percentage are managed at other facilities, despite 1 in 10 requiring neurosurgical operation regardless of level of trauma center. This analysis provides preliminary data on the function of regionalized trauma care for older adult TBI care. Future studies assessing the efficacy of early care guidelines in this population are warranted.

Survey of Diagnostic and Management Practices in Small Bowel Obstruction: Individual and Generational Variation Despite Practice Guidelines.

Background: Small bowel obstruction (SBO) is a common disorder managed by surgeons. Despite extensive publications and management guidelines, there is no universally accepted approach to its diagnosis and management. We conducted a survey of acute care surgeons to elucidate their SBO practice patterns.Methods: A self-report survey of SBO diagnosis and management practices was designed and distributed by email to AAST surgeons who cared for adult SBO patients. Responses were analyzed with descriptive statistics and Chi-square test of independence at α = .05.Results: There were 201 useable surveys: 53% ≥ 50 years, 77% male, 77% at level I trauma centers. Only 35.8% reported formal hospital SBO management guidelines. Computed tomography (CT) scan was the only diagnostic exam listed as "essential" by the majority of respondents (82.6%). Following NG decompression, 153 (76.1%) would "always/frequently" administer a water-soluble contrast challenge (GC). There were notable age differences in approach. Compared to those ≥50 years, younger surgeons were less likely to deem plain abdominal films as "essential" (16.0% vs 40.2%; P < .01) but more likely to require CT scan (88.3% vs 77.6%; P = .045) for diagnosis and to "always/frequently" administer GC (84.0% vs 69.2%; P < .01). Younger surgeons used laparoscopy "frequently" more often than older surgeons (34.0% vs 21.5%, P = .05).Discussion: There is significant variation in diagnosis and management of SBO among respondents in this convenience sample, despite existing PMGs. Novel age differences in responses were observed, which prompts further evaluation. Additional research is needed to determine whether variation in practice patterns is widespread and affects outcomes.

The public health burden of geriatric trauma: Analysis of 2,688,008 hospitalizations from Centers for Medicare and Medicaid Services inpatient claims.

BACKGROUND: Geriatric trauma care (GTC) represents an increasing proportion of injury care, but associated public health research on outcomes and expenditures is limited. The purpose of this study was to describe GTC characteristics, location, diagnoses, and expenditures. METHODS: Patients at short-term nonfederal hospitals, 65 years or older, with ≥1 injury International Classification of Diseases, Tenth Revision, were selected from 2016 to 2019 Centers for Medicare and Medicaid Services Inpatient Standard Analytical Files. Trauma center levels were linked to Inpatient Standard Analytical Files data via American Hospital Association Hospital ID and fuzzy string matching. Demographics, care location, diagnoses, and expenditures were compared across groups. RESULTS: A total of 2,688,008 hospitalizations (62% female; 90% White; 71% falls; mean Injury Severity Score, 6.5) from 3,286 hospitals were included, comprising 8.5% of all Medicare inpatient hospitalizations. Level I centers encompassed 7.2% of the institutions (n = 236) but 21.2% of hospitalizations, while nontrauma centers represented 58.5% of institutions (n = 1,923) and 37.7% of hospitalizations. Compared with nontrauma centers, patients at Level I centers had higher Elixhauser scores (9.0 vs. 8.8) and Injury Severity Score (7.4 vs. 6.0; p < 0.0001). The most frequent primary diagnosis at all centers was hip/femur fracture (28.3%), followed by traumatic brain injury (10.1%). Expenditures totaled $32.9 billion for trauma-related hospitalizations, or 9.1% of total Medicare hospitalization expenditures and approximately 1.1% of the annual Medicare budget. The overall mortality rate was 3.5%. CONCLUSION: Geriatric trauma care accounts for 8.5% of all inpatient GTC and a similar percentage of expenditures, the most common injury being hip/femur fractures. The largest proportion of GTC occurs at nontrauma centers, emphasizing their vital role in trauma care. Public health prevention programs and GTC guidelines should be implemented by all hospitals, not just trauma centers. Further research is required to determine the optimal role of trauma systems in GTC, establish data-driven triage guidelines, and define the impact of trauma centers and nontrauma centers on GTC mortality. LEVEL OF EVIDENCE: Therapeutic/care management, Level III.

A mathematical model to predict length of stay in pediatric ATV accident victims.

BACKGROUND: Children under age 12 y represent 15% of all-terrain vehicle (ATV)-related deaths, and those under 16 y old represent >36% of deaths nationwide. In recent years, this has accounted for an increasing proportion of pediatric trauma victims and longer hospitalizations secondary to worsened injuries. We believe it is possible to create a simple mathematical model that can be used to predict hospital length of stay. METHODS: A retrospective review of the trauma registry was performed for all pediatric patients who were involved in ATV accidents from January 2000 to December 2009. Four hundred twenty pediatric patients were identified. A model to predict for total LOS in pediatric patients involved in ATV accidents was constructed. SPSS ver. 17 (SPSS Inc., Chicago, IL) was utilized to conduct all statistical analyses. Statistical significance of regression coefficients was assumed at a P < 0.05 level. RESULTS: We performed a hierarchical multiple regression analysis to build a model that would predict for total length of stay (LOS). A logarithmic transformation was employed on LOS as a dependent variable due to skewness. In Step 1, ISS accounted for a 25% increase in shared variance in LOS (P < 0.001). In Step 2, Glasgow Coma Score (GCS) accounted for 4.3% more variance in LOS (P < 0.001). Finally, in Step 3, the presence of a closed head injury further increased (3.6%) the amount of shared variance in the model (P < 0.001). The final model accounts for 32.9% of the shared variance in total LOS. When using the logarithmic transformation, the final model is: Total LOS = 1.00 + 0.05 injury severity score (ISS) - 0.06 (GCS) + 0.35 closed head injury (CHI). CONCLUSION: Based on our data and statistical analysis, we found it was possible to create a mathematical model that could predict hospital LOS in pediatric ATV accident victims.

Blunt cerebrovascular injury practice management guidelines: the Eastern Association for the Surgery of Trauma.

BACKGROUND: Blunt injury to the carotid or vertebral vessels (blunt cerebrovascular injury [BCVI]) is diagnosed in approximately 1 of 1,000 (0.1%) patients hospitalized for trauma in the United States with the majority of these injuries diagnosed after the development of symptoms secondary to central nervous system ischemia, with a resultant neurologic morbidity of up to 80% and associated mortality of up to 40%. With screening, the incidence rises to 1% of all blunt trauma patients and as high as 2.7% in patients with an Injury Severity Score of >or=16. The Eastern Association for the Surgery of Trauma organization Practice Management Guidelines committee set out to develop an EBM guideline for the screening, diagnosis, and treatment of BCVI. METHODS: A computerized search of the National Library of Medicine/National Institute of Health, Medline database was performed using citations from 1965 to 2005 inclusive. Titles and abstracts were reviewed to determine relevance, and isolated case reports, small case series, editorials, letters to the editor, and review articles were eliminated. The bibliographies of the resulting full-text articles were searched for other relevant citations, and these were obtained as needed. These papers were reviewed based on the following questions: 1. What patients are of high enough risk, so that diagnostic evaluation should be pursued for the screening and diagnosis of BCVI? 2. What is the appropriate modality for the screening and diagnosis of BCVI? 3. How should BCVI be treated? 4. If indicated, for how long should antithrombotic therapy be administered? 5. How should one monitor the response to therapy? RESULTS: One hundred seventy-nine articles were selected for review, and of these, 68 met inclusion criteria and are excerpted in the attached evidentiary table and used to make recommendations. CONCLUSIONS: The East Practice Management Guidelines Committee suggests guidelines that should be safe and efficacious for the screening, diagnosis, and treatment of BCVI. Risk factors for screening are identified (see ), screening modalities are reviewed indicating that although angiography remains the gold standard, multi-planar (>or==8 slice) CT angiography may be equivalent, and treatment algorithms are evaluated. It is noted that change in the diagnosis and management of this injury constellation is rapid due to technological advancement and the difficulties inherent in performing randomized prospective trials in this patient population.

Understanding the Trauma/Acute Care Surgery Workforce.

As the roles of trauma/acute care surgeons continue to evolve, it is imperative that health-care systems adapt to meet workforce needs. Tailoring retention strategies that elicit workforce satisfaction ensure continued coverage that is mutually beneficial to surgeons and health-care systems. We sought to elicit factors related to career characteristics and expectations of the trauma/acute care surgery (ACS) workforce to assist with such future progress. In this study, 1552 Eastern Association for the Surgery of Trauma members were anonymously surveyed. Data collected included demographics, career expectations, and motivators of trauma/ACS. Four hundred eight (26%) Eastern Association for the Surgery of Trauma members responded. Respondents were 78 per cent male and had a median age of 47.3 years. Forty-six per cent of surgeons reported earning $351K-$475K and 23 per cent >$475K. At this point in their career, 49 per cent of surgeons felt quality of life was "most important", followed by 31 per cent career ambitions and 13 per cent salary. Prominent career satisfiers were patient care and teaching. Greatest detractors were burnout, bureaucracy, and work environment. Eighty per cent would change jobs in the final 10 years of practice, 31 per cent because of family/retirement, 29 per cent because of professional growth, 24 per cent because of workload, and 7 per cent because of salary. This study could be used to help develop trauma/ACS workforce strategies. This workforce remains mobile into late career; personal happiness and patient ownership overshadow financial rewards, and most prefer a total and shared patient care model compared with no patient ownership. Burnout, bureaucracy, and work environment are dominant detractors of job satisfaction among surveyed trauma/ACS surgeons.

Practice management guidelines for the screening of thoracolumbar spine fracture.

BACKGROUND: Fractures to the thoracolumbar spine (TLS) commonly occur because of major trauma mechanisms. In one series, 4.4% of all patients arriving at a Level I trauma center were diagnosed as having TLS fracture. Approximately 19% to 50% of these fractures in the TLS region will be associated with neurologic damage to the spinal cord. To date there are no randomized studies and only a few prospective studies specifically addressing the subject. The Eastern Association for the Surgery of Trauma organization Practice Management Guidelines committee set out to develop an EBM guideline for the diagnosis of TLS fractures. METHODS: A computerized search of the National Library of Medicine and the National Institutes of Health MEDLINE database was undertaken using the PubMed Entrez (www.pubmed.gov) interface. The primary search strategy was developed to retrieve English language articles focusing on diagnostic examination of potential TLS injury published between 1995 and March 2005. Articles were screened based on the following questions. (1) Does a patient who is awake, nonintoxicated, without distracting injuries require radiographic workup or a clinical examination only? (2) Does a patient with a distracting injury, altered mental status, or pain require radiographic examination? (3) Does the obtunded patient require radiographic examination? RESULTS: Sixty-nine articles were identified after the initial screening process, all of which dealt with blunt injury to the TLS, along with clinical, radiographic, fluoroscopic, and magnetic resonance imaging evaluation. From this group, 32 articles were selected. The reviewers identified 27 articles that dealt with the initial evaluation of TLS injury after trauma. CONCLUSION: Computed tomography (CT) scan imaging of the bony spine has advanced with helical and currently multidetector images to allow reformatted axial collimation of images into two-dimensional and three-dimensional images. As a result, bony injuries to the TLS are commonly being identified. Most blunt trauma patients require CT to screen for other injuries. This has allowed the single admitting series of CT scans to also include screening for bony spine injuries. However, all of the publications fail to clearly define the criteria used to decide who gets radiographs or CT scans. No study has carefully conducted long-term follow-up on all of their trauma patients to identify all cases of TLS injury missed in the acute setting.

Paying it forward: Four-year analysis of the Eastern Association for the Surgery of Trauma Mentoring Program.

BACKGROUND: Mentorship programs in surgery are used to overcome barriers to clinical and academic productivity, research success, and work-life balance. We sought to determine if the Eastern Association for the Surgery of Trauma (EAST) Mentoring Program has met its goals of fostering academic and personal growth in young acute care surgeons. METHODS: We conducted a systematic program evaluation of EAST Mentoring Program's first 4 years. Demographic information was collected from EAST records, mentorship program applications, and mentee-mentor career development plans. We reviewed the career development plans for thematic commonalities and results of a structured, online questionnaire distributed since program inception. A mixed methods approach was used to better understand the program goals from both mentee and mentor perspectives, as well as attitudes and barriers regarding the perceived success of this career development program. RESULTS: During 2012 to 2015, 65 mentoring dyads were paired and 60 completed the program. Of 184 surveys distributed, 108 were returned (57% response rate). Respondents were evenly distributed between mentees and mentors (53 vs. 55, p = 0.768). In participant surveys, mentoring relationships were viewed to focus on research (45%), "sticky situations" (e.g., communication, work-life balance) (27%), education (18%), or administrative issues (10%). Mentees were more focused on research and education versus mentors (74% vs. 50%; p = 0.040). Mentees felt that goals were "always" or "usually" met versus mentors (89% vs. 77%; p = 0.096). Two barriers to successful mentorship included time and communication, with most pairs communicating by email. Most respondents (91%) planned to continue the relationship beyond the EAST Mentoring Program and recommended the experience to colleagues. CONCLUSION: Mentee satisfaction with the EAST Mentoring Program was high. Mentoring is a beneficial tool to promote success among EAST's young members, but differences exist between mentee and mentor perceptions. Revising communication expectations and time commitment to improve career development may help our young acute care surgeons.

Missile embolism to the pulmonary artery: case report and pitfalls of management.

Missile embolism to the pulmonary artery is a rare event. We present a complicated case of missile embolism from the inferior vena cava to the pulmonary artery. The case illustrates the potential pitfalls in the management of these patients.

Early evaluation of acute traumatic coagulopathy by thrombelastography.

Posttraumatic coagulopathy is a major cause of morbidity. This prospective study evaluated the thrombelastography (TEG) system and PlateletMapping (Haemoscope Corporation, Niles, Ill) values posttrauma, and it correlated those values with transfusions and fatalities. After institutional review board approval, assays were performed on 161 trauma patients. One citrated blood sample was collected onsite (OS), and 1 citrate and 1 heparinized sample were collected within 1 h of arrival to the emergency department (ED). Paired and unpaired t-testing was performed for nominal data with chi square testing for categorical values. Except for a slight increase in clot strength (maximal amplitude (MA)), there were no significant changes from OS to the ED. None of the TEG parameters were significantly different for the 22 patients who required transfusion. PlateletMapping showed lower platelet adenosine diphosphate (ADP) responsiveness in patients who needed transfusions (MA = 22.7 +/- 17.1 vs MA = 35.7 +/- 19.3, P = 0.004) and a correlation of fibrinogen <100 mg/dL with fatalities (P = 0.013). For the 14 fatalities, TEG reaction (R) time was 3703 +/- 11,618 versus 270 +/- 393 s (P = < 0.001), and MA was 46.4 +/- 22.4 versus 64.7 +/- 9.8 mm (P < 0.001). Hyperfibrinolysis (percent fibrinolysis after 60 min (LY60) >15%) was observed in 3 patients in the ED with a 67% fatality rate (P = < 0.001 by chi-square testing). PlateletMapping assays correlated with the need for blood transfusion. The abnormal TEG System parameters correlated with fatality. These coagulopathies were already evident OS. The TEG assays can assess coagulopathy, platelet dysfunction, and hyperfibrinolysis at an early stage posttrauma and suggest more effective interventions.
