RESUMEN
BACKGROUND: Despite the high incidence of blunt trauma in older adults, there is a lack of evidence-based guidance for computed tomography (CT) imaging in this population. We aimed to identify an algorithm to guide use of a Pan-Scan (Head/C-spine/Torso) or a Selective Scan (Head/C-spine ± Torso). We hypothesized that a patient's initial history and exam could be used to guide imaging. METHODS: We prospectively studied blunt trauma patients aged 65+ at 18 Level I/II trauma centers. Patients presenting >24 h after injury or who died upon arrival were excluded. We collected history and physical elements and final injury diagnoses. Injury diagnoses were categorized into CT body regions of Head/C-spine or Torso (chest, abdomen/pelvis, and T/L spine). Using machine learning and regression modeling as well as a priori clinical algorithms based, we tested various decision rules against our dataset. Our priority was to identify a simple rule which could be applied at the bedside, maximizing sensitivity (Sens) and negative predictive value (NPV) to minimize missed injuries. RESULTS: We enrolled 5,498 patients with 3,082 injuries. Nearly half (47.1%, n = 2,587) had an injury within the defined CT body regions. No rule to guide a Pan-Scan could be identified with suitable Sens/NPV for clinical use. A clinical algorithm to identify patients for Pan-Scan, using a combination of physical exam findings and specific high-risk criteria, was identified and had a Sens of 0.94 and NPV of 0.86 This rule would have identified injuries in all but 90 patients (1.6%) and would theoretically spare 11.9% (655) of blunt trauma patients a torso CT. CONCLUSIONS: Our findings advocate for Head/Cspine CT in all geriatric patients with the addition of torso CT in the setting of positive clinical findings and high-risk criteria. Prospective validation of this rule could lead to streamlined diagnostic care of this growing trauma population. LEVEL OF EVIDENCE: Level 2, Diagnostic Tests or Criteria.
RESUMEN
BACKGROUND: Birthdays provide an opportunity to celebrate; however, they can also be associated with various adverse medical events. This is the first study to examine the association between birthdays and in-hospital trauma team evaluation. METHODS: This retrospective study analyzed trauma registry patients 19-89 years of age, who were evaluated by in-hospital trauma services from 1/1/2011 to 12/31/2021. RESULTS: 14,796 patients were analyzed and an association between trauma evaluation and birthdays was found. The strongest incidence rate ratios (IRRs) were on the day of birth (IRR: 1.78; P < .001) followed by ±3 days of the birthday (IRR: 1.21; P = .003). When incidence was analyzed by age groups, 19-36 years of age had the strongest IRR (2.30; P < .001) on their birthday, followed by the >65 groups (IRR: 1.34; P = .008) within ±3 days. Non-significant associations were seen in the 37-55 (IRR: 1.41; P = .209) and 56-65 groups (IRR: 1.60; P = .172) on their birthday. Patient-level characteristics were only significant for the presence of ethanol at trauma evaluation (risk ratio: 1.83; P = .017). DISCUSSION: Birthdays and trauma evaluations were found to have a group-dependent association, with the greatest incidence for the youngest age group being on their birthday, and the oldest age group within ±3 days. The presence of alcohol was found to be the best patient-level predictor of trauma evaluation.

Background: Acute care surgery (ACS) has grown and evolved since it was conceived in 2005. However, ACS is not recognized in the National Library of Medicine's Medical Subject Heading thesaurus. This article uses bibliometrics to help define an identity for ACS as a subspecialty of surgery and argue for its addition to the Medical Subject Heading thesaurus. Methods: The terms "Acute Care Surgery," "Wounds and Injuries," "General Surgery," and "Critical Care" were searched with and without the Text Word [TW] modifier using PubMed. The intersections of search sets were identified with the AND conjunction to determine the proportion of ACS literature relevant to each subject term and calculate the penetration of ACS as a keyword term into each subject domain. Results: A [Medical Subject Heading] limited search on the term "Acute Care Surgery" yielded a predictable return of 0 article. Search of the cohesive term "Acute Care Surgery" [All Fields], restricted to MEDLINE-indexed, English-language articles yielded 2,351 articles published between 2005 and 2020, inclusive. Using ACS as [Text Word] yielded 517 articles. There was a progressive increase in the rate of annual publications. The frequency of subject terms in the ACS [All Fields] set was as follows: Critical Care, 49.70%; General Surgery, 23.26%; and Wounds and Injuries, 20.88%. The frequency of subject terms in the ACS [TW] set was as follows: Critical Care, 32.88%; General Surgery, 43.52%; and Wounds and Injuries, 15.28%. Of this set, 8.32% of articles were not tagged or did not contain a reference to any of these 3 major subjects. Conclusion: This study demonstrates that ACS as a subject matter is being increasingly expressed in the literature. Adding ACS as a dedicated term into the National Library of Medicine's Medical Subject Heading thesaurus of controlled vocabulary as a specialty of Surgery would facilitate indexing and retrieval of the literature most relevant to acute care surgeons.
RESUMEN
INTRODUCTION: Physical stressors are common predisposing factors for takotsubo cardiomyopathy (TTC). However, the role of traumatic injuries in TTC has not been well defined. This study describes the characteristics of TTC in the broad spectrum of traumatic injuries using the information available in the National Trauma Data Bank (NTDB). MATERIALS AND METHODS: This retrospective study analyzed trauma patients ≥ 18 years old in the NTDB, from 2007 to 2018, with a diagnosis of TTC. RESULTS: A total of 95 TTC diagnoses were found. The median age was 68 years old (interquartile range: 55-80). Patients were predominantly female (67.4%), white (88.4%), and sustained blunt mechanisms of injury (90.5%). Penetrating trauma was most common in males (16%). Most diagnoses were related to extremity trauma (53.7%), followed by head injury (26.3%). The most common severity scores were Glasgow Coma Scale (GCS) > 13 or < 8, and Injury Severity Score (ISS) < 15 or > 25. Males more commonly presented with GCS < 8 (68%), ISS > 25 (33%), high intensive care unit (ICU) admission rate (77.4%), and mechanical ventilation (51.6%). The median duration of the mechanical ventilation was eight days for both sexes. The ICU length of stay (LOS) was six days with a hospital LOS of nine days and a trend toward a longer LOS in males. The in-hospital mortality rate was 11.7% for both sexes. CONCLUSIONS: TTC in traumatic injuries is common at both ends of the severity spectrum and has different sex distribution. TTC patients are predominantly females and have more commonly extremity trauma than head injury. Males are more severely injured and under mechanical ventilation.
RESUMEN
BACKGROUND: Severe pain and pulmonary complications commonly follow rib fractures, both of which may be improved by surgical stabilization of rib fractures (SSRFs). However, significant postoperative pain still persists which may negatively impact in-hospital outcomes. Combining intercostal nerve cryoablation (INCA) with SSRF may improve those outcomes by further decreasing postoperative pain, opioid consumption, and pulmonary complications. The hypothesis is that INCA plus SSRF reduces opioids consumption compared with SSRF alone. METHODS: The retrospective analysis included trauma patients 18 years or older who underwent SSRF, with or without INCA, in a Level I trauma center between 2015 and 2021. Patients received INCA at the surgeons' discretion based on familiarity with the procedure and absence of contraindications. Patients without INCA were the historical control group. Reported data include demographics, mechanism and severity of injury, number of ribs stabilized, cryoablated nerves, intubation rates and duration of mechanical ventilation. The primary outcome was total morphine milligrams equivalent consumption. Secondary outcomes were intensive care unit length of stay, hospital length of stay, incidence of pneumonia, and tracheostomy rates, and discharge disposition. Long-term outcomes were examined up to 6 months for adverse events. RESULTS: Sixty-eight patients were included, with 44 receiving INCA. There were no differences in rates of pneumonia ( p = 0.106) or duration of mechanical ventilation ( p = 0.687), and hospital length of stay was similar between groups ( p = 0.059). However, the INCA group demonstrated lower total morphine milligrams equivalent ( p = 0.002), shorter intensive care unit length of stay ( p = 0.021), higher likelihood of home discharge ( p = 0.044), and lower rate of intubation ( p = 0.002) and tracheostomy ( p = 0.032). CONCLUSION: Combining INCA with SSRF may further improve in-hospital outcomes for patients with traumatic rib fractures. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

INTRODUCTION: Enoxaparin dosed by an anti-Xa trough level is effective at reducing venous thromboembolism (VTE) in trauma patients. We identified the patient characteristics associated with higher enoxaparin dosing based on anti-Xa trough levels. METHODS: A retrospective review was conducted on trauma patients admitted between August 2014 and February 2018 who received enoxaparin dosed by the anti-Xa trough level. Patients who received enoxaparin < 50 mg every 12 hours were compared to those who required ≥ 50 mg every 12 hours. RESULTS: Of the 246 patients included, 32 (13.0%) required enoxaparin ≥ 50 mg every 12 hours to achieve the prophylactic trough level. Factors associated with a higher dose of enoxaparin were male (96.8% vs. 3.2%, P < .01), younger age (39.5 vs. 52.7 years, P < .01), higher creatinine clearance (CrCl) (125.9 vs. 93.7 mL/min, P < .01), higher body surface area (2 m2 vs. 1.8 m2, P < .01), and higher injury severity score (18.4 vs. 10.8, P < .01). Height, weight, and body mass index were not significant factors. On regression analysis, CrCl was the only independent predictor for higher enoxaparin dose. There was an increased deep venous thrombosis rate in the higher dose cohort (12.5% vs. 0, P < .01) but no significant differences in transfusion rates. CONCLUSION: Trauma patients who require higher enoxaparin doses to achieve prophylactic anti-Xa trough levels have a higher CrCl. Patients with high CrCl may benefit from an initial higher dose of enoxaparin to achieve a target anti-Xa level in a shorter time interval to decrease VTE risk.
