A nationwide analysis of geriatric proximal humerus fractures: trends, outcomes, and cost.

Background: In the USA, proximal humerus fractures (PHF) are the third most common fracture among the elderly. Although most geriatric PHF are treated conservatively, surgical management remains an option. This retrospective study compares annual trends, patient outcomes, and hospital costs between operatively and non-operatively managed geriatric PHF. Methods: The Healthcare Cost and Utilization Project Nationwide Inpatient Sample was queried from 2012 to 2015. Geriatric patients with PHF were identified and those who underwent operative or non-operative management were compared in trends, outcomes and costs. Results: In total, 137 810 patients met inclusion criteria, of which 51 795 (37.6%) underwent operative management. The operative cohort was younger (76.6 vs 80.9, p<0.001) with a greater proportion of females (81.8% vs 77.6%, p<0.001). The operative cohort demonstrated less frailty and lower Elixhauser Comorbidity Scores (both p<0.001). The operative cohort was also more likely to be discharged home (30.4% vs 13.9%, p<0.001). There was no significant linear trend in age-adjusted and sex-adjusted proportions of operative versus non-operative geriatric PHF (p=0.071), but a positive linear trend was statistically significant for total cost of operative geriatric PHF (p<0.001). Multivariable analyses demonstrated similar overall complication rates between cohorts (OR 0.95, 95% CI 0.89 to 1.00; p=0.06), although surgical intervention increased length of stay (LOS) by 0.15 days (95% CI 0.03 to 0.27; p<0.001) and median cost of hospitalization by US$10 684 (95% CI US$10 384 to US$10 984; p<0.001). Conclusions: This study identifies a positive linear trend in total cost of operatively managed geriatric PHF from 2012 to 2015. Operative management of geriatric PHF is associated with a similar overall complication rate and greater likelihood of being discharged home. Although non-operative management is associated with decreased LOS and hospital expenses, providers should consider surgical PHF treatment options when available and appropriate in the context of patient-focused outcomes, particularly long-term disposition after intervention. Level of Evidence: This level IV retrospective study identifies.

Association Between Health Insurance and Outcomes After Traumatic Brain Injury: A National ACS-TQP-PUF Database Study.

INTRODUCTION: According to the US Census Bureau, roughly 8.6% of the population lacks health care coverage. Increasing evidence suggests that insurance status plays a role in outcomes after trauma. However, its role in the setting of traumatic brain injury (TBI) remains poorly understood. METHODS: The Trauma Quality Programs Participant Use Files were queried from 2017 to 2019. All patients with isolated TBI were identified. Isolated TBI was defined as: 1) Head Abbreviated Injury Scale (AIS) > 3 and 2) AIS <3 in all other anatomical regions. Patients dead on arrival, with Head AIS = 6, or missing key data were excluded. Demographic and clinical information was compared between those with and without insurance. Multivariate regressions were used to assess associations between insurance status and TBI outcomes (inhospital mortality, discharge to facility, total ventilator days, Intensive Care Unit length of stay (ICU LOS), and hospital LOS). RESULTS: In total, 199,556 patients met inclusion criteria; 18,957 (9.5%) were uninsured. Compared to the insured, uninsured TBI patients were younger with a greater proportion of males. Uninsured patients were less severely injured and less comorbid. Uninsured patients had shorter unadjusted LOS in the ICU and hospital. Yet, uninsured patients experienced greater unadjusted inhospital mortality (12.7% versus 8.4%, P < 0.001). When controlling for covariates, lack of insurance was significantly associated with increased likelihood of mortality (OR 1.62; P < 0.001). This effect was most noticeable in patients with Head AIS = 4 (OR 1.55; P < 0.001) and Head AIS = 5 (OR 1.80; P < 0.001). Lack of insurance was also significantly associated with decreased likelihood of discharge to facility (OR 0.38), decreased ICU LOS (Coeff. -0.61), and decreased hospital LOS (Coeff. -0.82; all P < 0.001). CONCLUSIONS: This study demonstrates that insurance status is independently associated with outcome disparities after isolated TBI. Despite the Affordable Care Act (ACA) reform, lack of insurance appears significantly associated with inhospital mortality, decreased likelihood of discharge to facility, and decreased time spent in the ICU and hospital.

TRAUMATIC BRAIN INJURY-INDUCED INFLAMMATION AND GASTROINTESTINAL MOTILITY DYSFUNCTION.

ABSTRACT: Background: Traumatic brain injury (TBI) is a significant cause of morbidity and mortality in the United States, with an annual cost of 60 billion dollars. There is evidence suggesting that in the post-TBI period, the gastrointestinal tract plays a central role in driving organ and immune dysfunction and may be the source of increased circulating proinflammatory mediators. In this study, we examined systemic inflammation and bacterial dysbiosis in patients who sustained a TBI with or without polytrauma. Using a mouse model of TBI, we further show how neuroinflammation after TBI is potentially linked to disruptions in gut homeostasis such as intestinal transit and inflammation. Methods: During a study of trauma patients performed from September 1, 2018, to September 1, 2019, at a single, level 1 trauma center, TBI patients aged 21 to 95 years were enrolled. Patients were categorized as TBI based on evidence of acute abnormal findings on head computed tomographic scan, which was a combination of isolated TBI and TBI with polytrauma. Blood and stool samples were collected between 24 h and 3 days after admission. Twelve plasma samples and 10 fecal samples were used for this study. Healthy control samples were obtained from a healthy control biobank. We examined systemic inflammation and bacterial changes in patients who sustained a TBI. In addition, TBI was induced in 9- to 10-week-old male mice; we assessed neuroinflammation, and intestine transit (motility) and bacterial changes 24 h after TBI. Results: When compared with healthy controls, TBI patients had increased systemic inflammation as evidenced by increased levels of IFN-γ and MCP-1 and a trend toward an increase of IL-6 and IL-8 ( P = 0.0551 and P = 0.0549), respectively. The anti-inflammatory cytokine, IL-4, was also decreased in TBI patients. Although there was a trend of an increase in copy number of Enterobacteriaceae and a decrease in copy number of Lactobacillus in both patients and mice after TBI, these trends were not found to be significantly different. However, TBI significantly increased the copy number of another potential pathogenic bacteria Bilophila wadsworthia in TBI patients compared with healthy controls. After a moderate TBI, mice had increased expression of TNF-α, IL-6 and IL-1ß, CXCL1, s100a9, and Ly6G and decreased IL-10 in the brain lesion after TBI. This accompanied decreased transit and increased TNF-α in the small intestine of mice after TBI. Conclusions: Our findings suggest that TBI increases systemic inflammation, intestinal dysfunction, and neuroinflammation. More studies are needed to confirm whether changes in intestinal motility play a role in post-TBI neuroinflammation and cognitive deficit.

A multicenter validation of the modified brain injury guidelines: Are they safe and effective?

BACKGROUND: The modified Brain Injury Guidelines (mBIG) are an algorithm for treating patients with traumatic brain injury and intracranial hemorrhage by which selected patients do not require a repeat head computed tomography, a neurosurgery consult, or even an admission. The mBIG refined the original Brain Injury Guidelines (BIG) to improve safety and reproducibility. The purpose of this study is to assess safety and resource utilization with mBIG implementation. METHODS: The mBIG were implemented at three Level I trauma centers in August 2017. A multicenter retrospective review of prospectively collected data was performed on adult mBIG 1 and 2 patients. The post-mBIG implementation period (August 2017 to February 2021) was compared with a previous BIG retrospective evaluation (January 2014 to December 2016). RESULTS: There were 764 patients in the two study periods. No differences were identified in demographics, Injury Severity Score, or admission Glasgow Coma Scale score. Fewer computed tomography scans (2 [1,2] vs. 2 [2,3], p < 0.0001) and neurosurgery consults (61.9% vs. 95.9%, p < 0.0001) were obtained post-mBIG implementation. Hospital (2 [1,4] vs. 2 [2,4], p = 0.013) and intensive care unit (0 [0,1] vs. 1 [1,2], p < 0.0001) length of stay were shorter after mBIG implementation. No difference was seen in the rate of clinical or radiographic progression, neurosurgery operations, or mortality between the two groups.After mBIG implementation, eight patients (1.6%) worsened clinically. Six patients that clinically progressed were discharged with Glasgow Coma Scale score of 15 without needing neurosurgery intervention. One patient had clinical and radiographic decompensation and required craniotomy. Another patient worsened clinically and radiographically, but due to metastatic cancer, elected to pursue comfort measures and died. CONCLUSION: This prospective validation shows the mBIG are safe, pragmatic, and can dramatically improve resource utilization when implemented. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

Professionalism of Admitting and Consulting Services and Trauma Patient Outcomes.

OBJECTIVE: To determine whether trauma patients managed by an admitting or consulting service with a high proportion of physicians exhibiting patterns of unprofessional behaviors are at greater risk of complications or death. SUMMARY BACKGROUND DATA: Trauma care requires high-functioning interdisciplinary teams where professionalism, particularly modeling respect and communicating effectively, is essential. METHODS: This retrospective cohort study used data from 9 level I trauma centers that participated in a national trauma registry linked with data from a national database of unsolicited patient complaints. The cohort included trauma patients admitted January 1, 2012 through December 31, 2017. The exposure of interest was care by 1 or more high-risk services, defined as teams with a greater proportion of physicians with high numbers of patient complaints. The study outcome was death or complications within 30 days. RESULTS: Among the 71,046 patients in the cohort, 9553 (13.4%) experienced the primary outcome of complications or death, including 1875 of 16,107 patients (11.6%) with 0 high-risk services, 3788 of 28,085 patients (13.5%) with 1 high-risk service, and 3890 of 26,854 patients (14.5%) with 2+ highrisk services (P < 0.001). In logistic regression models adjusting for relevant patient, injury, and site characteristics, patients who received care from 1 or more high-risk services were at 24.1% (95% confidence interval 17.2% to 31.3%; P < 0.001) greater risk of experiencing the primary study outcome. CONCLUSIONS: Trauma patients who received care from at least 1 service with a high proportion of physicians modeling unprofessional behavior were at an increased risk of death or complications.

Rhabdomyolysis: an American Association for the Surgery of Trauma Critical Care Committee Clinical Consensus Document.

Rhabdomyolysis is a clinical condition characterized by destruction of skeletal muscle with release of intracellular contents into the bloodstream. Intracellular contents released include electrolytes, enzymes, and myoglobin, resulting in systemic complications. Muscle necrosis is the common factor for traumatic and non-traumatic rhabdomyolysis. The systemic impact of rhabdomyolysis ranges from asymptomatic elevations in bloodstream muscle enzymes to life-threatening acute kidney injury and electrolyte abnormalities. The purpose of this clinical consensus statement is to review the present-day diagnosis, management, and prognosis of patients who develop rhabdomyolysis.

Multicenter assessment of the Brain Injury Guidelines and a proposal of guideline modifications.

BACKGROUND: The Brain Injury Guidelines provide an algorithm fortreating patients with traumatic brain injury (TBI) and intracranial hemorrhage(ICH) that does not mandate hospital admission, repeat head CT, orneurosurgical consult for all patients. The purposes of this study are toreview the guidelines' safety, to assess resource utilization, and to proposeguideline modifications that improve patient safety and widespreadreproducibility. METHODS: A multi-institutional review of TBI patients was conducted. Patients with ICH on CT were classified as BIG 1, 2, or 3 based on the guidelines. BIG 3 patients were excluded. Variables collected included demographics, Injury Severity Score (ISS), hospital length of stay (LOS), intensive care unit LOS, number of head CTs, type of injury, progression of injury, and neurosurgical interventions performed. RESULTS: 269 patients met inclusion criteria. 98 were classifiedas BIG 1 and 171 as BIG 2. The median length of stay (LOS) was 2 (2,4)days and the ICU LOS was 1 (0,2) days. Most patients had a neurosurgeryconsultation (95.9%) and all patients included had a repeat head CT. 370repeat head CT scans were performed, representing 1.38 repeat scans perpatient. 11.2% of BIG 1 and 11.1% of BIG 2 patients demonstratedworsening on repeat head CT. Patients who progressed exhibited a higherISS (14 vs. 10, p=0.040), and had a longer length of stay (4 vs. 2 days;p=0.015). After adjusting for other variables, the presence of epiduralhematoma (EDH) and intraparenchymal hematoma were independent predictors ofprogression. Two BIG 2 patients with EDH had clinical deteriorationrequiring intervention. DISCUSSION: The Brain Injury Guidelines may improve resourceallocation if utilized, but alterations are required to ensure patientsafety. The modified Brain Injury Guidelines refine the originalguidelines to enhance reproducibility and patient safety while continuing toprovide improved resource utilization in TBI management.

Is Tracheostomy Insertion an Indication for Gastrostomy Insertion?

The aim of the study was to determine the frequency of surgical patients who undergo tracheostomy and gastrostomy insertion during the same hospitalization. Secondary outcomes included ICU and hospital length of stay (LOS) for patients who underwent concomitant tracheostomy and gastrostomy versus those who did not. This study is a retrospective review of trauma and acute care surgery (ACS) patients between 2006 and 2015 who underwent tracheostomy. Patients who also underwent open gastrostomy or percutaneous endoscopic gastrostomy during the same hospitalization were identified. Data collected included patient demographics, hospital LOS, ICU LOS, and timing of tracheostomy and gastrostomy. Three hundred one trauma and ACS patients who underwent tracheostomy were identified. Seventy- three per cent of tracheostomy patients underwent gastrostomy during the same admission. Of patients who had both tubes inserted, 79 per cent (175) underwent gastrostomy with tracheostomy as the concomitant procedure, whereas 21 per cent received gastrostomy as a delayed procedure. Median hospital LOS for patients who underwent concomitant procedures was 25 days versus 22 days for those who had delayed or no gastrostomy (P = 0.24). Eighty-four per cent of patients who had tracheostomy for prolonged or anticipated prolonged mechanical ventilation were receiving tube feeds at discharge, and 78 per cent had not been advanced to an oral diet at discharge. Most trauma/ACS patients who undergo tracheostomy also undergo gastrostomy during their hospitalization. Concomitant gastrostomy is not associated with a decrease in hospital LOS; however, most patients who undergo tracheostomy for prolonged mechanical ventilation are discharged receiving enteral nutrition. These patients may benefit from concomitant ICU gastrostomy as a way to improve efficiency and cost-saving.

Clearing the cervical spine in patients with distracting injuries: An AAST multi-institutional trial.

BACKGROUND: Single institution studies have shown that clinical examination of the cervical spine (c-spine) is sensitive for clearance of the c-spine in blunt trauma patients with distracting injuries. Despite an unclear definition, most trauma centers still adhere to the notion that distracting injuries adversely affect the sensitivity of c-spine clinical examination. A prospective AAST multi-institutional trial was performed to assess the sensitivity of clinical examination screening of the c-spine in awake and alert blunt trauma patients with distracting injuries. METHODS: During the 42-month study period, blunt trauma patients 18 years and older were prospectively evaluated with a standard c-spine examination protocol at 8 Level 1 trauma centers. Clinical examination was performed regardless of the presence of distracting injuries. Patients without complaints of neck pain, tenderness or pain on range of motion were considered to have a negative c-spine clinical examination. All patients with positive or negative c-spine clinical examination underwent computed tomography (CT) scan of the entire c-spine. Clinical examination findings were documented prior to the CT scan. RESULTS: During the study period, 2929 patients were entered. At least one distracting injury was diagnosed in 70% of the patients. A c-spine injury was found on CT scan in 7.6% of the patients. There was no difference in the rate of missed injury when comparing patients with a distracting injury to those without a distracting injury (10.4% vs. 12.6%, p = 0.601). Only one injury missed by clinical examination underwent surgical intervention and none had a neurological complication. CONCLUSIONS: Negative clinical examination may be sufficient to clear the cervical spine in awake and alert blunt trauma patients, even in the presence of a distracting injury. These findings suggest a potential source for improvement in resource utilization. LEVEL OF EVIDENCE: Therapeutic/care management, level IV.

Defining Outcomes after Colon Resection in Blunt Trauma: Is Diversion or Primary Anastomosis More Favorable?

Previous literature demonstrates the safety of primary repair in penetrating colon injury requiring resection, without the creation of a diverting ostomy. It is unknown whether a similar approach can be applied to patients with blunt colon injury. The aim of this study was to measure outcomes in patients who underwent colon resection with and without ostomy creation after blunt trauma injury to help direct future management. Using the National Trauma Data Bank for years 2008 to 2012, we identified patients with blunt trauma mechanisms who underwent colectomy. Patients were stratified into two groups: primary anastomosis and diversion with ostomy. Primary outcome was inpatient mortality. Secondary outcomes included length of stay and perioperative complications. All risk-adjusted analyses were performed using logistic regression with consideration of interactions. Five hundred eighty-one observations met our inclusion criteria. Baseline characteristics between the two groups were similar with the exception of age (37.3 vs 42.2 years, P < 0.001) and admission Glasgow coma score (13.2 vs 12.1, P = 0.002). Risk-adjusted mortality for the two groups was not statistically significant (2.3% vs 3.0%, P = 0.63); however, patients with primary anastomosis had a shorter length of stay (18.2 vs 28.1, P < 0.001), fewer days in the intensive care unit (10.9 vs 16.2, P < 0.001), and fewer ventilator days (10.5 vs 14.6, P = 0.01). In patients requiring colon resection after blunt trauma, mortality is not different for those who receive a primary anastomosis versus ostomy. Patients without diversion had shorter hospital stays, intensive care unit days, and ventilator days. These data support that primary anastomosis is safe in this patient population.

Superusers: Drivers of health care resource utilization in the national trauma population.

BACKGROUND: Health care spending is driven by a very small percentage of Americans, many of whom are patients with prolonged durations of stay. The objective of this study was to characterize superusers in the trauma population. METHODS: The National Trauma Data Bank for 2008-2012 was queried. Superusers were defined as those with a duration of stay in the top 0.06% of the population and were compared with the remainder of the population to determine differences in demographic characteristics, comorbidities, prehospital factors, and outcomes. Multivariate analysis was used to determine independent predictors of being classified as a superuser. RESULTS: A total of 3,617,261 patients met inclusion criteria, with 34,728 qualifying as superusers. Mean duration of stay for superusers was 58.7 days compared with the average 4.6 days (P < .001). Superusers were more likely to be male, black, Medicaid insured, and have a higher Injury Severity Score and lower Glasgow Coma Scale score. The hospital course of superusers was likely to be complicated by pneumonia, acute respiratory distress syndrome, decubitus ulcer, and acute kidney injury. CONCLUSION: Age, sex, race, and insurance were associated with prolonged use of inpatient care in the trauma patient population. Specific comorbidities and complications are associated with being a superuser. This subset of the trauma population confers a disproportionate burden on the health care system and can serve as a potential target for intervention.

The National Trauma Data Bank story for emergency department thoracotomy: How old is too old?

BACKGROUND: The fastest growing segment of the American population is the elderly (>65 years). This change in demographics also is being seen in trauma centers. Emergency department thoracotomy is utilized in an attempt to restore circulation for patients arriving in extremis. The purpose of this study was to investigate the relationship between clinical variables, particularly age, and outcomes for injured patients receiving an emergency department thoracotomy. METHODS: Using the National Trauma Data Bank for years 2008-2012, observations with International Classification of Diseases, Ninth Revision, Clinical Modification procedure codes for exploratory thoracotomy were identified. Emergency department thoracotomy was defined as any observation that occurred at a time to thoracotomy less than the total time spent in the emergency department thoracotomy, and within 15 minutes of arrival. Mechanisms of injury, demographic data, and injuries were analyzed for predictors of survival and mortality rates. Mortality rates were determined for each decade and year of life. RESULTS: There were 11,380 observations for thoracotomy identified. Of these, 2,519 were emergency department thoracotomy, with the majority (n= 2,026, 80% observations) performed for penetrating wounds. Mortality rates ranged from 80% to 100% for each decade of life. Mortality was 100% for patients >57 years old with either penetrating or blunt mechanisms of injury. CONCLUSION: Emergency department thoracotomy offered no survival benefit for patients older than 57 years of age. These data suggest that emergency department thoracotomy performed in elderly patients may be futile.

Indicators of Survival and Favorable Functional Outcomes after Decompressive Craniectomy: A Multi-Institutional Retrospective Study.

The role of decompressive craniectomy (DC) for severe traumatic brain injury (STBI) remains controversial. The purpose of this study was to identify factors that are indicators of survival and improved functional outcome in patients who undergo DC for STBI. A retrospective review of STBI patients who underwent DC was performed at four trauma centers during a 45-month period. Data collected included age, gender, mechanism of injury, Injury Severity Score (ISS), admission Glasgow Coma Scale (GCS), time from admission to DC, mortality, and extended Glasgow Outcome Score before discharge. Sixty-nine STBI patients were treated with DC during the study period. A higher initial GCS, lower ISS, and longer time to DC were all statistically significant for improved survival after DC. A younger age, higher initial GCS, and lower ISS were all statistically significant for a favorable functional outcome after DC. Patients with a higher initial GCS and lower ISS are more likely to survive DC and have a favorable functional outcome, whereas a longer time to DC was indicative of improved survival after DC.

Rib fractures and their association With solid organ injury: higher rib fractures have greater significance for solid organ injury screening.

BACKGROUND: The purpose of this study was to identify patients with rib injuries who were at risk for solid organ injury. METHODS: A retrospective chart review was performed of all blunt trauma patients with rib fractures during the period from July 2007 to July 2012. Data were analyzed for association of rib fractures and solid organ injury. RESULTS: In all, 1,103 rib fracture patients were identified; 142 patients had liver injuries with 109 (77%) associated right rib fractures. Right-sided rib fractures with highest sensitivity for liver injury were middle rib segment (5 to 8) and lower segment (9 to 12) with liver injury sensitivities of 68% and 43%, respectively (P < .001); 151 patients had spleen injuries with 119 (79%) associated left rib fractures. Left middle segment rib fractures and lower segment rib fractures had sensitivities of 80% and 63% for splenic injury, respectively (P < .003). CONCLUSIONS: Rib fractures higher in the thoracic cage have significant association with solid organ injury. Using rib fractures from middle plus lower segments as indication for abdominal screening will significantly improve rib fracture sensitivity for identification of solid organ injury.

Intraoperative management of renal gunshot injuries: is mandatory exploration of Gerota's fascia necessary?

BACKGROUND: Many trauma surgeons and trauma centers use routine exploration of Gerota's fascia (GE) for renal gunshot wounds (RGSW). The purpose of this study was to assess whether RGSW can be selectively explored for patients who undergo exploratory laparotomy. METHODS: Retrospective 10-year review of all patients who underwent exploratory laparotomy for abdominal gunshot wounds and had RGSW selectively explored. RESULTS: Sixty-three patients with RGSW underwent exploratory laparotomy. Twenty-eight (44%) underwent GE vs 35 (56%) who did not. Eight (29%) mortalities occurred with GE and 5 (14%) without GE (P < .05). Of GE patients, 14 (50%) had nephrectomy and 14 (50%) had renorrhaphy. Average hospital length of stay with GE was 16.7 days vs 17.9 without GE. Three (9%) renal-associated complications occurred without GE and 1 (4%) with GE. CONCLUSIONS: Most patients who suffer RGSW do not require exploration of GE during abdominal exploration. Complication rates due to nonexploration of RGSW are very low with infrequent need for surgical intervention due to renal-associated complications. High nephrectomy rates may be avoided when GE is averted.

Thoracolumbar spine clearance: Clinical examination for patients with distracting injuries.

BACKGROUND: The purpose of this study was to prospectively assess the sensitivity of clinical examination to screen for thoracolumbar spine (TLS) injury in awake and alert blunt trauma patients with distracting injuries. METHODS: From December 2012 to June 2014, all blunt trauma patients older than 13 years were prospectively evaluated as per standard TLS examination protocol at a Level 1 trauma center. Awake and alert patients with Glasgow Coma Scale (GCS) score of 14 or greater underwent clinical examination of the TLS. Clinical examination was performed regardless of distracting injuries. Patients with no complaints of pain or tenderness on examination of the TLS were considered clinically cleared of injury. Patients with distracting injuries, including those clinically cleared and those with complaints of TLS pain or tenderness, underwent computed tomographic scan of the entire TLS. Patients with minor distracting injuries were not considered to have a distracting injury. RESULTS: A total of 950 blunt trauma patients were entered, 530 (56%) of whom had at least one distracting injury. Two hundred nine patients (40%) with distracting injuries had a positive TLS clinical examination result, of whom 50 (25%) were diagnosed with TLS injury. Three hundred twenty-one patients (60%) with distracting injuries were initially clinically cleared, in whom 17 (5%) TLS injuries were diagnosed. There were no missed injuries that required surgical intervention, with only four injuries receiving TLS orthotic bracing. This yielded an overall clinical clearance sensitivity for injury of 75% and sensitivity for clinically significant injury of 89%. CONCLUSION: In awake and alert blunt trauma patients with distracting injuries, clinical examination is a sensitive screening method for significant TLS injury. Radiologic assessment may be unnecessary for safe clearance of the asymptomatic TLS in patients with distracting injuries. These findings suggest significant potential reduction of both health care cost and patient radiation exposure. LEVEL OF EVIDENCE: Diagnostic study, level IV; therapeutic/care management study, level IV.

Management of penetrating extraperitoneal rectal injuries: An Eastern Association for the Surgery of Trauma practice management guideline.

BACKGROUND: The management of penetrating rectal trauma invokes a complex decision tree that advocates the principles of proximal diversion (diversion) of the fecal stream, irrigation of stool from the distal rectum, and presacral drainage based on data from World War II and the Vietnam War. This guideline seeks to define the initial operative management principles for nondestructive extraperitoneal rectal injuries. METHODS: A systematic review of the MEDLINE database using PubMed was performed. The search retrieved English language articles regarding penetrating rectal trauma from January 1900 to July 2014. Letters to the editor, case reports, book chapters, and review articles were excluded. Topics of investigation included the management principles of diversion, irrigation of stool from the distal rectum, and presacral drainage using the GRADE methodology. RESULTS: A total of 306 articles were screened leading to a full-text review of 56 articles. Eighteen articles were used to formulate the recommendations of this guideline. CONCLUSION: This guideline consists of three conditional evidence-based recommendations. First, we conditionally recommend proximal diversion for management of these injuries. Second, we conditionally recommend the avoidance of routine presacral drains and distal rectal washout in the management of these injuries.
