A western trauma association multicenter comparison of mesh versus non-mesh repair of blunt traumatic abdominal wall hernias.

BACKGROUND: Blunt traumatic abdominal wall hernias (TAWH) occur in <1 % of trauma patients. Optimal repair techniques, such as mesh reinforcement, have not been studied in detail. We hypothesize that mesh use will be associated with increased surgical site infections (SSI) and not improve hernia recurrence. MATERIALS AND METHODS: A secondary analysis of the Western Trauma Association blunt TAWH multicenter study was performed. Patients who underwent TAWH repair during initial hospitalization (1/2012-12/2018) were included. Mesh repair patients were compared to primary repair patients (non-mesh). A logistic regression was conducted to assess risk factors for SSI. RESULTS: 157 patients underwent TAWH repair during index hospitalization with 51 (32.5 %) having mesh repair: 24 (45.3 %) synthetic and 29 (54.7 %) biologic. Mesh patients were more commonly smokers (43.1 % vs. 22.9 %, p = 0.016) and had a larger defect size (10 vs. 6 cm, p = 0.003). Mesh patients had a higher rate of SSI (25.5 % vs. 9.5 %, p = 0.016) compared to non-mesh patients, but a similar rate of recurrence (13.7 % vs. 10.5%, p = 0.742), hospital length of stay (LOS), and mortality. Mesh use (OR 3.66) and higher ISS (OR 1.06) were significant risk factors for SSI in a multivariable model. CONCLUSION: Mesh was used more frequently in flank TAWH and those with a larger defect size. Mesh use was associated with a higher incidence and risk of SSI but did not reduce the risk of hernia recurrence. When repairing TAWH mesh should be employed judiciously, and prospective randomized studies are needed to identify clear indications for mesh use in TAWH.

Impact of Standardized Multidisciplinary Critical Care Training on Confidence with Critical Illness and Attitudes Towards Interprofessional Education and Multidisciplinary Care.

INTRODUCTION: The Fundamental Critical Care Support Course (FCCS) is a standardized multidisciplinary program designed to educate participants on the basics of identification and management of patients with critical illness. Our objective was to evaluate the effect of FCCS participation on confidence in the assessment and management of critically ill patients and attitudes towards multidisciplinary education and interprofessional care in a multidisciplinary group of participants. METHODS: Participants enrolled in the FCCS course from May 2018 to November 2019 were solicited to participate in a series of surveys evaluating their course experience and confidence in critical care. Attitudes towards multidisciplinary education and interprofessional care were evaluated using the Student Perceptions of Interprofessional Clinical Education-Revised Instrument version 2 (SPICE-R2) tool. A prospective pre- and post-design with a self-report survey including retrospective pre-training assessment and a 3-month follow-up was conducted. Statistical analysis was performed using descriptive statics and non-parametric methods. RESULTS: 321 (97.9%) of the course participants enrolled in the study and completed the confidence survey and SPICE-R2 tool pre-course. Nurses (113, 35.4%) and physicians (110, 34.4%) made up the largest groups of participants, although physician assistants and paramedics were also well represented. Confidence in recognition and management of critical illness significantly improved across all studied domains after course completion, with the mean total confidence score improving from 32.96 pre-course to 41.10 post-course, P < 0.001. Attitudes towards multidisciplinary education and interprofessional care also improved (mean score 41.37 pre-course vs 42.71 post-course, P < 0.001), although pre-course numbers were higher than expected which limited the significance to only certain domains. DISCUSSION: In a multidisciplinary group, completion of FCCS training led to increased confidence in all aspects of critical illness measured. A modest increase in attitudes regarding multidisciplinary education and interprofessional care was also demonstrated. Further study is needed to assess whether this increased confidence translates to improvements in patient care and outcomes.

Issues and Strategies in Training Left-Handed Surgeons.

Left-hand dominance in surgery is a trait historically regarded as disadvantageous to both the trainee and trainer. The aim of this editorial was to identify challenges faced by left-handed trainees and trainers across multiple surgical specialties and to propose strategies that could be implemented during surgical training. Multiple themes were identified including left-handed surgeons experiencing discrimination due to their handedness. Additionally, a higher incidence of ambidexterity among left-handed trainees was noted, suggesting that left-handed surgeons may be adapting to a lack of accommodations for left-hand trainees. Also explored were the effects of handedness in training vs practice and the effects of handedness across subspecialties including orthopedic surgery, cardiothoracic surgery, and plastic surgery. Solutions discussed involved teaching both right-handed and left-handed surgeons' ambidexterity, pairing left-handed surgeons with left-handed trainees, having left-handed instruments available, adapting the surgical environment to the operating surgeon, communicating laterality, utilizing simulation centers or virtual reality, and encouraging prospective research looking at best-practices.

Ethical Implications of Nutrition Therapy at the End of Life.

PURPOSE OF REVIEW: Provide an evidence-based resource to inform ethically sound recommendations regarding end of life nutrition therapy. RECENT FINDINGS: • Some patients with a reasonable performance status can temporarily benefit from medically administered nutrition and hydration(MANH) at the end of life. • MANH is contraindicated in advanced dementia. • MANH eventually becomes nonbeneficial or harmful in terms of survival, function, and comfort for all patients at end of life. • Shared decision-making is a practice based on relational autonomy, and the ethical gold standard in end of life decisions. A treatment should be offered if there is expectation of benefit, but clinicians are not obligated to offer non-beneficial treatments. A decision to proceed or not should be based on the patient's values and preferences, a discussion of all potential outcomes, prognosis for given outcomes taking into consideration disease trajectory and functional status, and physician guidance provided in the form of a recommendation.

Risk factors for recurrence in blunt traumatic abdominal wall hernias: A secondary analysis of a Western Trauma association multicenter study.

BACKGROUND: Few studies have investigated risk factors for recurrence of blunt traumatic abdominal wall hernias (TAWH). METHODS: Twenty trauma centers identified repaired TAWH from January 2012 to December 2018. Logistic regression was used to investigate risk factors for recurrence. RESULTS: TAWH were repaired in 175 patients with 21 (12.0%) known recurrences. No difference was found in location, defect size, or median time to repair between the recurrence and non-recurrence groups. Mesh use was not protective of recurrence. Female sex, injury severity score (ISS), emergency laparotomy (EL), and bowel resection were associated with hernia recurrence. Bowel resection remained significant in a multivariable model. CONCLUSION: Female sex, ISS, EL, and bowel resection were identified as risk factors for hernia recurrence. Mesh use and time to repair were not associated with recurrence. Surgeons should be mindful of these risk factors but could attempt acute repair in the setting of appropriate physiologic parameters.

Legal Firearm Sales at State Level and Rates of Violent Crime, Property Crime, and Homicides.

INTRODUCTION: The effects of firearm sales and legislation on crime and violence are intensely debated, with multiple studies yielding differing results. We hypothesized that increased lawful firearm sales would not be associated with the rates of crime and homicide when studied using a robust statistical method. METHODS: National and state rates of crime and homicide during 1999-2015 were obtained from the United States Department of Justice and the Centers for Disease Control and Prevention. National Instant Criminal Background Check System background checks were used as a surrogate for lawful firearm sales. A general multiple linear regression model using log event rates was used to assess the effect of firearm sales on crime and homicide rates. Additional modeling was then performed on a state basis using an autoregressive correlation structure with generalized estimating equation estimates for standard errors to adjust for the interdependence of variables year to year within a particular state. RESULTS: Nationally, all crime rates except the Centers for Disease Control and Prevention-designated firearm homicides decreased as firearm sales increased over the study period. Using a naive national model, increases in firearm sales were associated with significant decreases in multiple crime categories. However, a more robust analysis using generalized estimating equation estimates on state-level data demonstrated increases in firearms sales were not associated with changes in any crime variables examined. CONCLUSIONS: Robust analysis does not identify an association between increased lawful firearm sales and rates of crime or homicide. Based on this, it is unclear if efforts to limit lawful firearm sales would have any effect on rates of crime, homicide, or injuries from violence committed with firearms.

When Can we Feed after a Gastrointestinal Bleed?

PURPOSE OF REVIEW: Gastrointestinal (GI) bleeding can carry minimal or significant risk for recurrent hemorrhage. Timing of feeding after GI bleeding remains an area of debate, and here we review the evidence supporting recommendations. RECENT FINDINGS: Improved understanding of the pathophysiology of GI bleeding and the evolution of treatment strategies has significantly altered the management of GI bleeding and the associated propensity for rebleeding. Early feeding following peptic ulcer bleeding remains ill-advised for high risk lesions while early initiation of liquid diets following cessation of esophageal variceal bleeding is appropriate and shortens hospital stays. Time to feeding following GI bleeding is inherently based on the disease etiology, severity, and risk of recurrent hemorrhage. With evolving standards of care, rates of rebleeding following endoscopic hemostasis are decreasing. Some evidence exists for early feeding however, larger multi-center trials are needed to help optimize timing of feeding in higher risk lesions.

Enoxaparin titrated by anti-Xa levels reduces venous thromboembolism in trauma patients.

BACKGROUND: Trauma is a major risk factor for the development of a venous thromboembolism (VTE). After observing higher than expected VTE rates within our center's Trauma Quality Improvement Program data, we instituted a change in our VTE prophylaxis protocol, moving to enoxaparin dosing titrated by anti-Xa levels. We hypothesized that this intervention would lower our symptomatic VTE rates. METHODS: Adult trauma patients at a single institution meeting National Trauma Data Standard criteria from April 2015 to September 2019 were examined with regards to VTE chemoprophylaxis regimen and VTE incidence. Two groups of patients were identified based on VTE protocol-those who received enoxaparin 30 mg twice daily without routine anti-Xa levels ("pre") versus those who received enoxaparin 40 mg twice daily with dose titrated by serial anti-Xa levels ("post"). Univariate and multivariate analyses were performed to define statistically significant differences in VTE incidence between the two cohorts. RESULTS: There were 1698 patients within the "pre" group and 1406 patients within the "post" group. The two groups were essentially the same in terms of demographics and risk factors for bleeding or thrombosis. There was a statistically significant reduction in VTE rate (p = 0.01) and deep vein thrombosis rate (p = 0.01) but no significant reduction in pulmonary embolism rate (p = 0.21) after implementation of the anti-Xa titration protocol. Risk-adjusted Trauma Quality Improvement Program data showed an improvement in rate of symptomatic pulmonary embolism from fifth decile to first decile. CONCLUSION: A protocol titrating prophylactic enoxaparin dose based on anti-Xa levels reduced VTE rates. Implementation of this type of protocol requires diligence from the physician and pharmacist team. Further research will investigate the impact of protocol compliance and time to appropriate anti-Xa level on incidence of VTE. LEVEL OF EVIDENCE: Therapeutic/care management, Level IV.

Early feeding after percutaneous endoscopic gastrostomy tube placement in patients who require trauma and surgical intensive care: A retrospective cohort study.

BACKGROUND: Critically ill patients experience interruptions in enteral nutrition (EN). For ventilated patients who undergo percutaneous endoscopic gastrostomy (PEG) tube placement, postprocedure fasting times vary from 1 to 24 h depending on the surgeon's preference. There is no evidence to support delayed feeding (DF) after PEG placement. This study's purpose was to determine if there is an increased complication rate associated with early feeding (EF) after PEG. METHODS: 150 adult ventilated patients in the trauma and surgical intensive care unit (TSICU) at a level I trauma center underwent PEG placement in March 2015 through May 2018 by one of six surgical intensivists. Retrospective review revealed variable post-PEG fasting practices: one started EN at 1 h, two started at 4 h, two started at 6 h, and one started at 24 h. Time to initiation of EN and complication rates were assessed. Patients were divided into EF (<4) and DF (≥4 h) groups. RESULTS: Median postprocedure fasting time was 5.5 h. The overall complication rate was 3.3%, with a feeding intolerance rate of 0.7% and aspiration rate of 0%. There was no difference in complication rate for EF (3.1%) as compared with DF (3.4%) (odds ratio, 0.92; 95% CI, 0.10-8.52; P = 0.7). CONCLUSION: Complication rates following PEG placement in ventilated TSICU patients are low and do not change with EF compared with DF. EF is probably safe.

Management of blunt traumatic abdominal wall hernias: A Western Trauma Association multicenter study.

BACKGROUND: Blunt traumatic abdominal wall hernias (TAWH) occur in approximately 15,000 patients per year. Limited data are available to guide the timing of surgical intervention or the feasibility of nonoperative management. METHODS: A retrospective study of patients presenting with blunt TAWH from January 2012 through December 2018 was conducted. Patient demographic, surgical, and outcomes data were collected from 20 institutions through the Western Trauma Association Multicenter Trials Committee. RESULTS: Two hundred and eighty-one patients with TAWH were identified. One hundred and seventy-six (62.6%) patients underwent operative hernia repair, and 105 (37.4%) patients underwent nonoperative management. Of those undergoing surgical intervention, 157 (89.3%) were repaired during the index hospitalization, and 19 (10.7%) underwent delayed repair. Bowel injury was identified in 95 (33.8%) patients with the majority occurring with rectus and flank hernias (82.1%) as compared with lumbar hernias (15.8%). Overall hernia recurrence rate was 12.0% (n = 21). Nonoperative patients had a higher Injury Severity Score (24.4 vs. 19.4, p = 0.010), head Abbreviated Injury Scale score (1.1 vs. 0.6, p = 0.006), and mortality rate (11.4% vs. 4.0%, p = 0.031). Patients who underwent late repair had lower rates of primary fascial repair (46.4% vs. 77.1%, p = 0.012) and higher rates of mesh use (78.9% vs. 32.5%, p < 0.001). Recurrence rate was not statistically different between the late and early repair groups (15.8% vs. 11.5%, p = 0.869). CONCLUSION: This report is the largest series and first multicenter study to investigate TAWHs. Bowel injury was identified in over 30% of TAWH cases indicating a significant need for immediate laparotomy. In other cases, operative management may be deferred in specific patients with other life-threatening injuries, or in stable patients with concern for bowel injury. Hernia recurrence was not different between the late and early repair groups. LEVEL OF EVIDENCE: Therapeutic/care management, Level IV.

A case of burn evisceration with full-thickness injury to abdominal wall, bowel, bladder, and three extremities.

BACKGROUND: Severe electrical burns are a rare cause of admission to major burn centers. Incidence of electrical injury causing full-thickness injury to viscera is an increasingly scarce, but severe presentation requiring rapid intervention. We report one of few cases of a patient with full-thickness electrical injury to the abdominal wall, bowel, and bladder. CASE REPORT: The patient, a 22-year-old male, was transferred to our institution from his local hospital after sustaining a suspected electrical burn. On arrival the patient was noted to have severe burn injuries to the lower abdominal wall with evisceration of multiple loops of burned small bowel as well as burns to the groin, left upper, and bilateral lower extremities. In the trauma bay, primary and secondary surveys were completed, and the patient was taken for CT imaging and then emergently to the operating room. On exploration, the patient had massive full-thickness burns to the lower abdominal wall, five full-thickness burns to small bowel, and intraperitoneal bladder rupture secondary to full-thickness burn. The patient underwent damage-control laparotomy including enterectomies, debridement of bladder coagulative necrosis, and layered closure of bladder injury followed by temporary abdominal closure with vacuum dressing. The patient also underwent right leg escharotomy and partial right foot fasciotomies. The patient was subsequently transferred to the nearest burn center for continued resuscitation and comprehensive burn care. CONCLUSION: Severe electrical burns can be associated with devastating visceral injuries in rare cases. Though uncommon, these injuries are associated with very high mortality rates. The authors assert that rapid evaluation and initial stabilization following ATLS guidelines, damage-control laparotomy, and goal-directed resuscitation in concert with transfer to a major burn center are essential in effecting a successful outcome in these challenging cases.

Burkitt-type lymphoma incidentally found as the cause of acute appendicitis: a case report and review of literature.

BACKGROUND: Appendectomy remains one of the most common emergency operations. Recent research supports the treatment of uncomplicated appendicitis with antibiotics alone. While nonoperative management of appendicitis may be safe in some patients, it may result in missed neoplasms. We present a case of acute appendicitis where the final pathology resulted in a diagnosis of a Burkitt-type lymphoma. CASE PRESENTATION: An 18-year-old male presented to the emergency department with 24 h of right lower quadrant pain with associated urinary retention, anorexia, and malaise. Past medical history was significant for intermittent diarrhea and anal fissure. He exhibited focal right lower quadrant tenderness. Workup revealed leukocytosis and CT uncovered acute appendicitis with periappendiceal abscess and no appendicolith. Laparoscopic appendectomy was performed and found acute appendicitis with associated abscess abutting the rectum and bladder. Pathology of the resected appendix reported acute appendicitis with evidence of Burkitt-type lymphoma. A PET scan did not reveal any residual disease. Hematology/oncology was consulted and chemotherapy was initiated with an excellent response. CONCLUSIONS: Appendiceal lymphomas constitute less than 0.1% of gastrointestinal lymphomas. Primary appendix neoplasms are found in 0.5-1.0% of appendectomy specimens following acute appendicitis. In this case, appendectomy allowed for prompt identification and treatment of an aggressive, rapidly fatal lymphoma resulting in complete remission.

Tracheostomy and Gastrostomy in Geriatric Trauma Associated With High Postdischarge Mortality.

OBJECTIVES: Identify 5-year mortality rates in trauma patients greater than 18 years old who undergo tracheostomy and/or gastrostomy tube placement. DESIGN: Retrospective convenience sample with two cohorts. SETTING: Academic level 1 trauma center. PATIENTS: Hospitalized patients admitted to the trauma service from July 2008 to December 2012 who underwent tracheostomy and/or gastrostomy tube placement. INTERVENTIONS: Patients were placed into two cohorts: adult 18-64 and geriatric greater than or equal to 65; mortality data were obtained from the National Death Index. MEASUREMENTS AND MAIN RESULTS: The primary outcome was 5-year mortality of both cohorts as well as those admitted who did not receive tracheostomy or gastrostomy. Univariate analysis was performed using Fisher exact and Wilcoxon signed-rank tests. Kaplan-Meier curves were plotted to examine mortality up to 5 years after discharge. CONCLUSIONS: Five-year postdischarge mortality is significantly higher in geriatric patients undergoing tracheostomy and/or gastrostomy after traumatic injury. Fifty percent die within the first 28 weeks following discharge and 93% die within 2 years.

Different Perceptions Exist Between Health Care Providers and the General Population Regarding the Importance of Findings on Additional Imaging for Trauma Consults.

BACKGROUND: Approximately one-third of additional imaging for trauma consults results in the discovery of new injuries. No studies have addressed the perception of these findings in non-health care providers. Our hypothesis was that significant differences in perception of the importance of injuries would exist between health care providers (HCPs) and the general population. METHODS: Six standardized scenarios were developed detailing common new injury findings on additional imaging in trauma consults. Demographics as well as information regarding the significance of findings, potential for change in care, and the importance of patient notification were collected. Surveys were electronically distributed to HCPs in our system and the public. Data analysis was performed with generalized linear modeling. RESULTS: A total of 339 public and 129 HCP surveys were returned. HCPs included attending staff, residents, and advanced care providers from a variety of specialties. Significant differences in perception were found in traumatic brain injury, spine fractures, and rib fractures, with HCPs rating most findings as less clinically important than the general population, while rating patient notification as more important. Perceived importance decreased with increased age in the general population. Increasing HCP age or length in practice did not significantly affect perception of clinical importance, except for rib fractures. DISCUSSION: Differences in perception exist regarding the significance of additional injuries between HCPs and the general population. Perceptions of the general population also change with age. Decisions to pursue additional imaging in trauma patients should include consideration of these differences in perception to help support quality patient-centered care.

The Prevalence of Beers Criteria Medication Use and Associations with Falls in Geriatric Patients at a Level 1 Trauma Center.

The Beers Criteria for Potentially Inappropriate Medication (PIM) use is a list of medications with multiple risks in older patients. Approximately 24 per cent use rate is reported in prior studies. Our objective was to determine the local PIM use and subsequent fall risk in geriatric trauma patients. We conducted a retrospective analysis of PIM use in all geriatric patients evaluated at our Level 1 trauma center between 2014 and 2017. Patients were identified from our trauma database. Pre-admission medication use was determined through medication reconciliation from our electronic medical record (EMR). Patients not undergoing medication reconciliation were excluded. After initial analysis, patients were stratified by age into three groups: 65 to 74, 75 to 84, and ≥85 years. Multivariate logistic regression analyses were used to calculate odds ratios of falls for specific PIMs. In all, 2181 patients met the inclusion criteria. Overall, 71.2 per cent of geriatric trauma patients were prescribed at least one PIM-73.1 per cent of falls compared with 68.6 per cent for other mechanisms. Specific PIM use varied by age group. PIMs associated with fall risk in all patients included antipsychotics, benzodiazepines, and diclofenac. For those aged 65 to 74 years, antihistamines, diclofenac, proton pump inhibitors, and promethazine were associated. In those aged 75 to 84 years, alprazolam, antipsychotics, benzodiazepines, cyclobenzaprine, diclofenac, and muscle relaxants were implicated. No significant associations were found for patients aged ≥85 years. PIM use at our trauma center seems to be rampant and well above the national average. Geriatric falls were associated with using ≥1 PIM and multiple specific PIMs implicated. We are designing a targeted educational program for local primary care physicians (PCPs) that will attempt to decrease geriatric PIM use.

Trauma Recidivism Postdischarge Mortality: Important Differences Exist between the Adult and Geriatric Populations.

Trauma recidivists are a high-risk patient population. The effects of recidivism on Geriatric trauma mortality have not been investigated. Our hypothesis is that trauma recidivism is associated with high postdischarge mortality after the initial index admission in both the geriatric and adult trauma populations. The trauma registry of our Level I trauma center was queried for patients evaluated between 2008 and 2012. Patients were stratified adult (18-64) and geriatric (≥65) groups and matched with mortality data from the National Death Index. Unique patients were identified and recidivists flagged. Statistical analysis was performed based on characteristics from the index admission using nonparametric tests, and Kaplan-Meier curves were plotted to examine postdischarge mortality after index admission for recidivists. A total of 8716 records met inclusion criteria; 800 recidivist records were identified representing 369 unique patients. Recidivists presented between 2 and 7 times. Recidivists were more likely to be male, required ICU admission and mechanical ventilation, had a longer median length of stay, were less likely to discharge home, and had a higher postdischarge mortality. Stratifying into adult and geriatric groups demonstrated significant differences in injury severity, injury patterns, length of stay, race, gender, mechanism, and postdischarge mortality. Recidivists demonstrated a higher postdischarge mortality in both groups with the geriatric group approaching 46 per cent. Trauma recidivists represent an at-risk group with significantly higher postdischarge mortality. Group characteristics differ significantly between the adult and geriatric recidivist populations. Further research is needed to identify modifiable risk factors in these populations to minimize risks of morbidity and mortality.

The two faces of intentional self-inflicted injury: High in-hospital mortality, low postdischarge mortality, but high readmission rates.

BACKGROUND: Intentional self-inflicted injuries present unique challenges in treatment and prevention. We hypothesized intentional self-inflicted injuries would have higher in-hospital and postdischarge mortality than nonintentional self-inflicted injuries trauma. METHODS: Adult patients evaluated 2008 to 2012 were identified in our trauma registry and matched with mortality data from the National Death Index. Intentional self-inflicted injuries were identified using E-Codes. Readmissions were identified and analyzed. Intentional self-inflicted injuries patients who died in-hospital were compared with those surviving to discharge. Univariate analysis was performed using nonparametric tests. Kaplan-Meier curves were plotted to compare mortality ≤5 years postdischarge between intentional self-inflicted injuries and non-intentional self-inflicted injuries patients. RESULTS: In the study, 8,716 patient records were evaluated with 245 (2.8%) classified as intentional self-inflicted injuries. Eighteen (7.8%) patients with intentional self-inflicted injuries had multiple admissions, compared with 352 (4.4%) patients with nonintentional self-inflicted injuries with readmissions (P = .0210). In-hospital mortality was higher for intentional self-inflicted injuries compared with patients with non-intentional self-inflicted injuries (18.7% vs 4.9%, P < .0001). Survival analysis demonstrated that patients with intentional self-inflicted injuries had significantly lower postdischarge mortality at multiple time points. CONCLUSION: Patients with intentional self-inflicted injuries trauma have high in-hospital mortality, but low postdischarge mortality. We attribute this to high lethality mechanisms but appropriate psychiatric treatment and rehabilitation. However, the high intentional self-inflicted injuries readmission rate indicates further study of intentional self-inflicted injuries follow-up is warranted. Better prevention strategies are needed to identify and intervene in patients at-risk for intentional self-inflicted injuries.

The Beers criteria: Not just for geriatrics anymore? Analysis of Beers criteria medications in nongeriatric trauma patients and their association with falls.

BACKGROUND: It has been well established that many classes of medications on the Beers list of Potentially Inappropriate Medications (PIMs) are associated with falls and injuries in the geriatric population, but little work has been performed to understand if similar relationships exist among the nongeriatric adult population. METHODS: A retrospective chart review of 32 months of trauma encounters at our Level I trauma center was performed in nongeriatric adults aged 18 years to 64 years. Encounters were reviewed by mechanism of injury and intake medication reconciliation. The data were then evaluated for associations between PIMs and falls. RESULTS: Of the 7,897 trauma encounters in the study period, 6,493 had completed medication reconciliation, and 4,154 were between the ages of 18 years and 64 years. There was a statistically significant disproportionate number of those who sustained a fall on psychoactive medications and proton pump inhibitors, and the odds of a trauma patient presenting as a fall were also significantly higher on these select classes of PIMs. CONCLUSION: The PIMs associated with falls in the geriatric population are also associated with falls in the nongeriatric population. This study supports the judicious prescribing of these medications, as they may have risks beyond what was originally thought. LEVEL OF EVIDENCE: Prognostic, level IV.

Short- and Long-Term Geriatric Mortality After Acute Traumatic Subdural Hemorrhage.

BACKGROUND: Acute subdural hemorrhage often occurs in those ≥65 years of age after trauma and tends to yield poor clinical outcomes. Previous studies have demonstrated a propensity toward high in-hospital mortality rates in this population; however, postdischarge mortality data are limited. The objective of the present study was to analyze short- and long-term mortality data after acute traumatic subdural hemorrhage in the geriatric population as well as review the impact of associated clinical variables including mechanism of injury, pre-morbid antithrombotic use, and need for surgical decompression on mortality rates. METHODS: We retrospectively reviewed 455 patients who presented with an isolated traumatic acute subdural hemorrhage to our level-1 trauma center over a 5 year period using our data registry. Patients were then cross-referenced in the National Social Security Death Index for postdischarge mortality rates. United States life tables were used for peer-controlled actuarial comparisons. RESULTS: Acute traumatic subdural hemorrhage is often a fatal injury in the geriatric population, especially if taking antithrombotics or requiring surgical decompression. Specifically, they have greater in-hospital mortality rates than adults with similar injuries and have significantly lower survival rates for several years following discharge compared with their peer-matched controls. CONCLUSIONS: Here, we found that age is a significant predictor of both short- and long-term survival after acute traumatic subdural hemorrhage. Moreover, the present study corroborates that the need for surgical decompression or the use of pre-morbid antithrombotic medications is associated with increased overall mortality.
