The Impact of Concurrent Multi-Service Coverage on Quality and Safety in Trauma Care.

BACKGROUND: At many trauma centers in the United States, one acute care surgeon is responsible for overnight coverage of both the emergency general surgery (EGS) and trauma services. The impact of this scheduling phenomenon on the quality and safety of trauma care has not been studied. METHODS: Overnight (12:00 AM to 7:00 AM) trauma admissions to an academic Level 1 trauma center from 2013-2015 were studied after the institution adopted this scheduling phenomenon. Admissions were divided into two groups based on whether the admitting surgeon covered only the trauma service, or both the trauma and EGS services ("multi-service coverage"). Four major outcomes (e.g., mortality and complications), six quality metrics (e.g., time to first OR visit and unplanned transfers to the ICU), and procedural utilization patterns were compared. RESULTS: A total of 1046 admissions were included. There were no differences in any major outcomes between the two exposure groups, including any National Trauma Data Bank-defined complication (OR 1.1, 95% CI 0.8-1.5, P= 0.5). Quality metrics dependent on the admitting surgeon remained unchanged, including attending presence at the highest-level trauma activations within 15 min of arrival (93% versus 86%, P= 0.07) and time to urgent operative intervention (68 min versus 82 min, P= 0.9). There were no differences in the number of laboratory and imaging studies (4.1 versus 4.1, P= 0.9) or bedside interventions (1.8 versus 2.1, P= 0.4) performed per patient by the admitting surgeon. Multivariate logistic regression did not identify multi-service coverage as an independent risk factor for adverse patient outcomes or quality metrics. CONCLUSIONS: Trauma admissions under a surgeon covering multiple services simultaneously had similar outcomes, quality metrics, and procedural utilization patterns compared to trauma admissions under surgeons covering only the trauma service. Despite concerns that multiple-service coverage may overburden one acute care surgeon, time-dependent quality metrics and studies done during the initial workup of trauma patients remained unchanged. These findings suggest that simultaneous trauma and EGS service coverage by one acute care surgeon does not adversely impact trauma patient care.

Unjustified Administration in Liberal Use of Tranexamic Acid in Trauma Resuscitation.

BACKGROUND: Early administration of tranexamic acid (TXA) has been widely implemented for the treatment of presumed hyperfibrinolysis in hemorrhagic shock. We aimed to characterize the liberal use of TXA and whether unjustified administration was associated with increased venous thrombotic events (VTEs). METHODS: We identified injured patients who received TXA between January 2016 and January 2018 by querying our Level 1 trauma center's registry. We retrospectively reviewed medical records and radiologic images to classify whether patients had a hemorrhagic injury that would have benefited from TXA (justified) or not (unjustified). RESULTS: Ninety-five patients received TXA for traumatic injuries, 42.1% were given by emergency medical services. TXA was considered unjustified in 35.8% of the patients retrospectively and in 52% of the patients when given by emergency medical services. Compared with unjustified administration, patients in the justified group were younger (47.6 versus 58.4; P = 0.02), more hypotensive in the field (systolic blood pressure: 107 ± 31 versus 137 ± 32 mm Hg; P < 0.001) and in the emergency department (systolic blood pressure: 97 ± 27 versus 128 ± 27; P < 0.001), and more tachycardic in emergency department (heart rate: 99 ± 29 versus 88 ± 19; P = 0.04). The justified group also had higher injury severity score (median 24 versus 11; P < 0.001), was transfused more often (81.7% versus 20.6%; P < 0.001), and had higher in-hospital mortality (39.3% versus 2.9%; P < 0.001), but there was no difference in the rate of VTE (8.2% versus 5.9%). CONCLUSIONS: Our results highlight a high rate of unjustified administration, especially in the prehospital setting. Hypotension and tachycardia were indications of correct use. Although we did not observe a difference in VTE rates between the groups, though, our study was underpowered to detect a difference. Cautious implementation of TXA in resuscitation protocols is encouraged in the meantime. Nonetheless, adverse events associated with unjustified TXA administration should be further evaluated.

Lack of Lymphocyte Recovery After Esophagectomy Predicts Overall and Recurrence-Free Survival.

BACKGROUND: Lymphocytes have become the target of cancer interventions through engineering or immune checkpoint antibodies. We previously found decreased lymphocyte counts to be a predictor of mortality and complications in trauma and cardiac surgery patients. We hypothesized lack of lymphocyte count recovery postoperatively would predict outcomes in esophagectomy patients. METHODS: A retrospective review of all patients undergoing esophagectomy for adenocarcinoma performed over 13 y at our center by a single surgeon after institutional review board approval was performed. Patients were grouped by postoperative lymphocytes counts: never low, low with recovery, and low without recovery. Resolution of lymphopenia was assessed by day 4. Primary end points were overall and recurrence-free survival. RESULTS: In total, 198 patients were included with a minimum 6-mo follow-up. Collectively the 5-y recurrence and overall survival rates were 36% and 50%, respectively. Recurrence was significantly higher at 5 y in patients with persistent lymphopenia (43%) compared with those who recovered (14% P = 0.0017) and those who never dropped (0% P = 0.0009). The persistent lymphopenia group had significantly lower survival (45%) compared with the two other groups (67% P = 0.0232). CONCLUSIONS: There is a significant decrease in the overall and recurrence-free survival in those patients whose lymphocyte count drops without recovery after their esophagectomy. These data imply differences in immune responses to the stress of surgery that can be measured with routine postoperative laboratory values and are indicative of overall outcomes.

Population of Patients With Traumatic Brain Injury in Skilled Nursing Facilities: A Decade of Change.

OBJECTIVE: To describe the natural history of patients with traumatic brain injury (TBI) admitted to skilled nursing facilities (SNFs) following hospitalizations. SETTING: Between 2005 and 2014. PARTICIPANTS: Adults who had incident admissions to skilled nursing facilities (SNFs) with a diagnosis of TBI. DESIGN: Retrospective review of the Minimum Data Set. MAIN MEASURES: Main variables were cognitive and physical function, length of stay, presence of feeding tube, terminal condition, and dementia. RESULTS: Incident admissions to SNFs increased annually from 17 247 patients to 20 787 from 2005 to 2014. The percentage of patients with activities of daily living score 23 or more decreased from 25% to 14% (P < .05). The overall percentage of patients with severe cognitive impairment decreased from 18% to 10% (P < .05). More patients had a diagnosis of dementia in 2014 compared with previous years (P < .05), and the presence of a terminal condition increased from 1% to 1.5% over the 10-year period (P < .05). The percentage of patients who stayed fewer than 30 days was noted to increase steadily over the 10 years, starting with 48% in 2005 and ending with 53% in 2013 (P < .05). CONCLUSION: Understanding past trends in TBI admissions to SNFs is necessary to guide appropriate discharge and predict future demand, as well as inform SNF policy and practice necessary to care for this subgroup of patients.

Evaluation of a Safer Opioid Prescribing Protocol (SOPP) for Patients Being Discharged From a Trauma Service.

The aims of this study were to evaluate the effects on opioid medication prescribing, patient opioid safety education, and prescribing of naloxone following implementation of a Safer Opioid Prescribing Protocol (SOPP) as part of the electronic health record (EHR) system at a Level I trauma center. This was a prospective observational study of the EHR of trauma patients pre- (n = 191) and post-(n = 316) SOPP implementation between 2014 and 2016. At a comparison Level I trauma site not implementing SOPP, EHRs for the same time period were assessed for any historical trends in opioid and naloxone prescribing. After SOPP implementation, the implementation site increased the use of nonnarcotic pain medication, decreased dispensing high opioid dose (≥100 MME [milligram morphine equivalent]), significantly increased the delivery of opioid safety education to patients, and initiated prescribing naloxone. These changes were not found in the comparison site. Opioid prescribing for acute pain can be effectively reduced in a busy trauma setting with a guideline intervention incorporated into an EHR. Guidelines can increase the use of nonnarcotic medications for the treatment of acute pain and increase naloxone coprescription for patients with a higher risk of overdose.

Trauma patients who present in a delayed fashion: a unique and challenging population.

BACKGROUND: A proportion of trauma patients present for evaluation in a delayed fashion after injury, likely due to a variety of medical and nonmedical reasons. There has been little investigation into the characteristics and outcomes of trauma patients who present delayed. We hypothesize that trauma patients who present in a delayed fashion are a unique population at risk of increased trauma-related complications. MATERIALS AND METHODS: This was a retrospective review from 2010-2015 at a Level I trauma center. Patients were termed delayed if they presented >24 hours after injury. Patients admitted within 24 hours of their injury were the comparison group. Charts were reviewed for demographics, mechanism, comorbidities, complications and outcomes. A subgroup analysis was done on patients who suffered falls. RESULTS: During the 5-y period, 11,705 patients were admitted. A total of 588 patients (5%) presented >24 h after their injury. Patients in the delayed group were older (65 versus 55 y, P < 0.001) and more likely to have psychiatric comorbidities (33% vs. 24%, P = 0.0001) than the control group. They were also more likely to suffer substance withdrawal (8.9% vs. 4.1%, P < 0.001) but had toxicology testing for drugs and alcohol done at significantly lower rates. Patients that presented delayed after falls were similar in age and injury severity score (ISS) but more likely to suffer substance withdrawal when compared to those with falls that presented within 24 hours. Patients with falls that presented delayed had toxicology testing at significantly lower rates than the comparison group. CONCLUSIONS: Trauma patients that present to the hospital in a delayed fashion have unique characteristics and are more likely to suffer negative outcomes including substance withdrawal. Future goals will include exploring strategies for early intervention, such as automatic withdrawal monitoring and social work referral for all patients who present in a delayed fashion.

Empiric antibiotics pending bronchoalveolar lavage data in patients without pneumonia significantly alters the flora, but not the resistance profile, if a subsequent pneumonia develops.

INTRODUCTION: Ventilator-associated pneumonia (VAP) occurs in up to 25% of mechanically ventilated patients, with an associated mortality up to 50%. Early diagnosis and appropriate empiric antibiotic coverage of VAP are crucial. Given the multitude of noninfectious clinical and radiographic anomalies within trauma patients, microbiology from bronchioalveolar lavage (BAL) is often needed. Empiric antibiotics are administered while awaiting BAL culture data. Little is known about the effects of these empiric antibiotics on patients with negative BAL microbiology if a subsequent VAP occurs during the same hospital course. METHODS: This is a retrospective chart review of intubated trauma patients undergoing BAL for suspected pneumonia over a 3-y period at a Level 1 trauma center. All patients with suspected VAP undergoing a BAL receive empiric antibiotics. If microbiology data are negative at 72 h, all antibiotics are stopped; however, if the BAL returns with ≥10(5) colony-forming units per milliliter, the diagnosis of VAP is confirmed. We divided patients into three groups. Group 1 consisted of patients in whom the initial BAL was positive for VAP. Group 2 consisted of patients with an initial negative BAL, who subsequently developed VAP at a later point in the hospital course. Group 3 consisted of patients with negative BAL who did not develop a subsequent VAP. RESULTS: We obtained 499 BAL specimens in 185 patients over the 3-y period. A total of 14 patients with 23 BAL specimens initially negative for VAP subsequently developed VAP later during the same hospital stay. These patients did not have an increase in the hospital length of stay, intensive care unit days, ventilator days, or mortality compared with those who had a positive culture on the first suspicion of VAP. There was a significant increase in the percentage of Enterobacter (21% versus 8%) and Morganella (8% versus 0%) as the causative organism in these 14 patients when the VAP occurred. Furthermore, the profile of the top two organisms in each group changed. Enterobacter (21%) and Pseudomonas (17%) were the principal organisms in the initial BAL-negative group, whereas the two predominant strains in the initial positive BAL group were methicillin-sensitive Staphylococcus aureus (21%) and Haemophilus influenza (11%). Interestingly, methicillin-resistant S. aureus remained the third most common organism in both groups. Empiric antibiotics also did not seem to induce the growth of multidrug-resistant organisms, and there was no increased rate of secondary infections such as Clostridium difficile. CONCLUSIONS: Ventilator-associated pneumonia remains a significant cause of morbidity and mortality in mechanically ventilated trauma patients. The diagnosis and treatment of VAP continue to be challenging. Once clinically suspected, empiric coverage decreases morbidity and mortality. Our data demonstrate that patients who receive empiric coverage exhibit a significantly different microbiologic profile compared with those who had an initial positive BAL culture. Initial empiric antibiotics in BAL-negative patients were not associated with an increase in multidrug-resistant organisms, hospital, or intensive care unit length of stay, ventilator days, and mortality or secondary infections.

What should we make of candidates for surgical critical care and acute care surgery fellowships recounting so many penetrating trauma cases in their personal statements?

A large proportion of surgical residents that are applying to surgical critical care(SCC) and acute care surgery(ACS) fellowships are describing cases where they cared for patients with injuries from penetrating trauma in their personal statements. These cases appear to have served as an inspiration for their fellowship and career decision. However a substantial percentage of training in these fellowships occurs in the ICU and there also have been steadily decreasing rates of operative penetrating trauma throughout the United States over the last several decades. This incongruity is explored and suggestions are made for formal mentorship to occur between surgical residents interested in further training in SCC and ACS and attendings practicing within these fields.

Comparison of surgical stabilization of rib fractures vs epidural analgesia on in-hospital outcomes.

INTRODUCTION: Surgical stabilization of rib fractures (SSRF) improves functional outcomes compared to controls, partly due to reduction in pain. We investigated the impact of early SSRF on pulmonary complications, mortality, and length of stay compared to non-operative analgesia with epidural analgesia (EA). METHODS: Retrospective cohort study of the Trauma Quality Improvement Program (TQIP) 2017 dataset for adults with rib fractures, excluding those with traumatic brain injury or death within twenty-four hours. Early SSRF and EA occurred within 72 h, and we excluded those who received both or neither intervention. Our primary outcome was a composite of pulmonary complications including acute respiratory distress syndrome (ARDS) or ventilator-associated pneumonia (VAP). Additional outcomes included unplanned endotracheal intubation, in-hospital mortality, and hospital and intensive care unit (ICU) length of stay (LOS) for those surviving to discharge. Multiple logistic and linear regressions were controlled for variables including age, sex, flail chest (FC), injury severity, additional procedures, and medical comorbidities. RESULTS: We included 1,024 and 1,109 patients undergoing early SSRF and EA, respectively. SSRF patients were more severely injured with higher rates of FC (42.8 vs 13.3%, p<0.001), Injury Severity Score (ISS) > 16 (56.9 vs 36.1%, p<0.001), and Abbreviated Injury Scale (AIS) Thorax > 3 (33.3 vs 12.2%, p<0.001). Overall, 49 (2.3%) of patients developed ARDS or VAP, 111 (5.2%) required unplanned intubation, and 58 (2.7%) expired prior to discharge. On multivariable analysis, SSRF was not associated with the primary composite outcome (OR: 1.65, 95%CI: 0.85-3.21). Early SSRF significantly predicted decreased risk of unplanned intubation (OR:0.59, 95%CI: 0.38-0.92) compared with early EA alone, however, was not a significant predictor of in-hospital mortality (OR: 1.27, 95%CI: 0.68-2.39). SSRF was associated with significantly longer hospital (Exp(ß): 1.06, 95%CI: 1.00-1.12, p = 0.047) and ICU LOS (Exp(ß): 1.17, 95%CI: 1.08-1.27, p<0.001). CONCLUSIONS: Aside from unplanned intubation, we observed no statistically significant difference in the adjusted odds of in-hospital pulmonary morbidity or mortality for patients undergoing early SSRF compared with early EA. Chest wall injury patients may benefit from referral to trauma centers where both interventions are available and appropriate surgical candidates may receive timely intervention.

Safety and Feasibility of Ultra-Restrictive Transfusion Protocol as a Blood-Preservation Strategy During Shortage Crises.

BACKGROUND: We hypothesized that implementation of new ultra-restrictive transfusion protocol in adult surgical intensive care units (SICU) was safe and feasible during pandemic-associated shortage crises. METHODS: Retrospective analysis two months pre- and post-implementation of ultra-restrictive transfusion protocol in March 2020 with hemoglobin cutoff of 6 g/dL (6.5 g/dL if ≥ 65 years old) for patients without COVID, active bleeding, or myocardial ischemia. RESULTS: We identified 16/93 and 27/168 patients PRE and POST meeting standard transfusion threshold (7 g/dL); within POST, 12 patients met ultra-restrictive cutoffs. There was no significant difference between PRE and POST in the rate of mortality, ischemic complications, or the number of transfusions per patient, however, the overall incidence of transfusion was lower in the POST group (7.1 vs 17.2%, p = 0.02). Patients received a mean (SD) of 4(3.8) and 2.4(1.5) PRBC transfusions pre- and post-implementation. Odds ratio of mortality in POST group was 0.62 (95%CI: 0.08-5.12) adjusted for age, sex, and SOFA score. CONCLUSIONS: Implementation of an ultra-restrictive transfusion protocol was feasible and effective as a blood- preservation strategy.

The association between household and neighborhood characteristics and COVID-19 related ICU admissions.

Introduction: Approaches to COVID-19 mitigation can be more efficiently delivered with a more detailed understanding of where the severe cases occur. Our objective was to assess which demographic, housing and neighborhood characteristics were independently and collectively associated with differing rates of severe COVID-19. Methods: A cohort of patients with SARS-CoV-2 in a single health system from March 1, 2020 to February 15, 2021 was reviewed to determine whether demographic, housing, or neighborhood characteristics are associated with higher rates of severe COVID-19 infections and to create a novel scoring index. Characteristics included proportion of multifamily homes, essential workers, and ages of the homes within neighborhoods. Results: There were 735 COVID-19 ICU admissions in the study interval which accounted for 61 percent of the state's ICU admissions for COVID-19. Compared to the general population of the state those admitted to the ICU with COVID-19 were disproportionately older, male sex, and were more often Black, Indigenous, People of Color. Patients disproportionately resided in neighborhoods with three plus unit multifamily homes, homes built before 1940, homes with more than one person to a room, homes of lower average value, and in neighborhoods with a greater proportion of essential workers. From this our COVID-19 Neighborhood Index value was comparatively higher for the ICU patients (61.1) relative to the population of Rhode Island (49.4). Conclusion: COVID-19-related ICU admissions are highly related to demographic, housing and neighborhood-level factors. This may guide more nuanced and targeted vaccine distribution plans and public health measures for future pandemics.

Impact of socioethnic factors on outcomes following traumatic brain injury.

BACKGROUND: Ethnic minorities and low income families tend to be in poorer health and have worse outcomes for a spectrum of diseases. Health care provider bias has been reported to potentially affect the distribution of care away from poorer communities, minorities, and patients with a history of substance abuse. Trauma is perceived as a disease of the poor and medically underserved. Minorities are overrepresented in low income populations and are also less likely to possess health insurance leading to a potential overlapping effect. Traumatic brain injury (TBI) is a predominant cause of mortality and long-term morbidity, which imposes a considerable social and financial burden. We therefore sought to determine the independent effect on outcome after TBI from race, insurance status, intoxication on presentation, and median income. METHODS: A 5-year retrospective chart review of admitted trauma patients aged 18 years and older to a Level I trauma center. Zip code of residency was a surrogate marker for socioeconomic status, because median income for each zip code is available from the US Census. Charts review included race, insurance status, mechanisms of trauma, and injuries sustained. Outcomes were placement of tracheostomy, hospital length of stay (HLOS), leaving Against Medical Advice (AMA), and discharge to home versus rehabilitation and mortality. RESULTS: A total of 3,101 TBI patients were included in the analyses. Multivariable logistic and proportional hazard regression analyses were undertaken adjusting for age, gender, Injury Severity Score, and mechanism. Rates of tracheostomy placement were unaffected by race, median income, or insurance status. Race and median income did not affect HLOS, but private insurance was associated with shorter HLOS and intoxication was associated with longer HLOS. Neither race nor intoxication affected rates of AMA, but higher income and private insurance was associated with lower rates of AMA. Non-Caucasian race and lack of insurance had significantly lower likelihood of placement in a rehabilitation center. Mortality was unaffected by race, increased in intoxicated patients, was variably affected by median income, and was lowest in patients with private insurance. CONCLUSIONS: An extremely complex interplay exists between socioethnic factors and outcomes after TBI. Few physicians would claim overt discrimination. Tracheostomy, the factor most directed by the surgeon, was unbiased by race, income, or insurance status. The likelihood of placement in a rehabilitation center was significantly impacted by both race and insurance status. Future prospective studies are needed to better address causation.

The development of a urinary tract infection is associated with increased mortality in trauma patients.

BACKGROUND: In October 2008, Medicare and Medicaid stopped paying for care associated with catheter-related urinary tract infections (UTIs). Although most clinicians agree UTIs are detrimental, there are little data to support this belief. METHODS: This is a retrospective review of trauma registry data from a Level I trauma center between 2003 and 2008. Two proportional hazards regressions were used for analyses. The first predicted acquisition of UTI as a function of indwelling urinary catheter use, adjusting for age, diabetes, gender, and injury severity. The second predicted hospital mortality as a function of UTI, covarying for age, gender, chronic obstructive pulmonary disease, congestive heart failure, hypertension, diabetes, pneumonia, and injury severity. RESULTS: After excluding patients who stayed in the hospital <3 days and those with a UTI on arrival, 5,736 patients were included in the study. Of these patients, 680 (11.9%) met criteria for a UTI, with 487 (71.6%) indwelling urinary catheter-related infections. Predictors of UTI included the interaction between age and gender (p = 0.0018), Injury Severity Score (p = 0.0021), and indwelling urinary catheter use (p < 0.001). The development of a UTI predicted the risk of in-hospital death as a patient's age increased (p = 0.002). Similar results were seen when only catheter-associated UTIs are included in the analysis. CONCLUSIONS: Indwelling urinary catheter use is connected to the development of UTIs, and these infections are associated with a greater mortality as the age of a trauma patients increases.

Impact of Direct Transport vs. Transfer on Out-of-Hospital Traumatic Cardiac Arrest.

BACKGROUND: Injured patients benefit from direct transport to a trauma center; however, it is unknown whether patients with traumatic out-of-hospital cardiac arrest (OHCA) benefit from initial resuscitation at the nearest emergency department (ED) if a trauma center is farther away. We hypothesized that patients with traumatic OHCA transported directly to a trauma center have less in-hospital mortality after initial resuscitation compared to those transferred from non-trauma centers. METHODS: We examined patients presenting with traumatic OHCA within our institutional trauma registry and the National Trauma Data Bank (NTDB) and excluded patients with ED mortality. Our primary outcome was all-cause mortality during index hospitalization; multiple logistic regression controlled for age, sex, injury severity score, mechanism of injury, signs of life, emergency surgery, and level I trauma center designation. RESULTS: We identified 271 and 1,138 adult patients with traumatic OHCA in our registry and the NTDB; 28% and 16% were transferred from another facility, respectively. Following initial resuscitation, patients transferred to a trauma center had higher in-hospital mortality than those transported directly in both our local and national cohorts (aOR: 2.27, 95%CI: 1.03-4.98, and aOR: 2.66, 95%CI: 1.35 - 5.26, respectively). DISCUSSION: Patients with traumatic OHCA transported directly to a trauma center may have increased survival to discharge compared to those transferred from another facility, even accounting for initial resuscitation. Further investigation should examine the impact of both physiologic and logistic factors including distance to trauma center, traffic, and weather patterns that may impact prehospital decision-making and destination selection.

Prehospital shock index outperforms hypotension alone in predicting significant injury in trauma patients.

BACKGROUND: The American College of Surgeons Resources for Optimal Care of the Injured Patient recommends using hypotension, defined as systolic blood pressure ≤90 mm Hg, as an indicator of a full team trauma activation. We hypothesized that an elevated shock index (SI) predicts significant traumatic injuries better than hypotension alone. METHODS: This is a retrospective cohort study analyzing full team trauma activations between February 2018 and January 2020, excluding transfers and those who had missing values for prehospital blood pressure or heart rate. We reviewed patients' demographics, prehospital and emergency department vitals, injury pattern, need for operation, and clinical outcomes. The primary outcome was rate of significant injury defined as identified injured liver, spleen, or kidney, pelvis fracture, long bone fracture, significant extremity soft tissue damage, hemothorax, or pneumothorax. RESULTS: Among 544 patients, 82 (15.1%) had prehospital hypotension and 492 had normal blood pressure. Of the patients with prehospital hypotension, 34 (41.5%) had a significant injury. There was no difference in age, gender, medical history, or injury pattern between the two groups. There was no difference between the two groups in rate of serious injury (41.5% vs. 46.1%, NS), need for emergent operation (31.7% vs. 28.1%, NS) or death (20.7% vs. 18.8%, NS). On the other hand, SI ≥1 was associated with increased rate of serious injury (54.6% vs. 43.4%, p=0.04). On a logistic regression analysis, prehospital hypotension was not associated with significant injury or need for emergent operation (OR 0.83, 95% CI 0.51 to 1.33 and OR 1.32, 95% CI 0.79 to 2.25, respectively). SI ≥1 was associated with both increased odds of significant injury and need for emergent operation (OR 1.57, 95% CI 1.01 to 2.44 and OR 1.64, 95% CI 1.01 to 2.66). DISCUSSION: SI was a better indicator and could replace hypotension to better categorize and triage patients in need of higher level of care. LEVEL OF EVIDENCE: Prognostic and epidemiologic, level III.

Time to Head Computed Tomography Protocol in Traumatic Brain Injury: A Quality Improvement Metric.

BACKGROUND: Early identification of traumatic brain injury (TBI) with head CT HCT should expedite operative decision-making and improve outcome. We aimed to determine whether an early HCT protocol in TBI patients would improve outcome. METHODS: A multidisciplinary protocol to obtain an HCT within 30 minutes from arrival for patients with GCS ≤ 13 was instituted on 1/1/2015. Our trauma registry was queried for patients evaluated between 3/2012 and 12/2015. Outcomes included compliance with protocol and in-hospital mortality. RESULTS: 346 patients presented with GCS ≤ 13. Patients PRE- (n=264) and POST-protocol (n=82) were similar in demographic and physiologic characteristics. Time to HCT was lower (35 vs. 77 min; p<0.001). POST-protocol had lower odds of mortality (OR 0.65, 95% CI 0.43-0.99) adjusting for age, gender, ISS and GCS. CONCLUSION: Implementing a protocol of early HCT for TBI optimized performance of the trauma team. Time to HCT could serve as a quality metric in TBI.

Avoiding Cribari gridlock 2: The standardized triage assessment tool outperforms the Cribari matrix method in 38 adult and pediatric trauma centers.

OBJECTIVES: The Cribari Matrix Method (CMM) is the current standard to identify over/undertriage but requires manual trauma triage reviews to address its inadequacies. The Standardized Triage Assessment Tool (STAT) partially emulates triage review by combining CMM with the Need For Trauma Intervention, an indicator of major trauma. This study aimed to validate STAT in a multicenter sample. METHODS: Thirty-eight adult and pediatric US trauma centers submitted data for 97,282 encounters. Mixed models estimated the effects of overtriage and undertriage versus appropriate triage on the odds of complication, odds of discharge to a continuing care facility, and differences in length of stay for both CMM and STAT. Significance was assessed at p <0.005. RESULTS: Overtriage (53.49% vs. 30.79%) and undertriage (17.19% vs. 3.55%) rates were notably lower with STAT than with CMM. CMM and STAT had significant associations with all outcomes, with overtriages demonstrating lower injury burdens and undertriages showing higher injury burdens than appropriately triaged patients. STAT indicated significantly stronger associations with outcomes than CMM, except in odds of discharge to continuing care facility among patients who received a full trauma team activation where STAT and CMM were similar. CONCLUSIONS: This multicenter study strongly indicates STAT safely and accurately flags fewer cases for triage reviews, thereby reducing the subjectivity introduced by manual triage determinations. This may enable better refinement of activation criteria and reduced workload.

Normal presenting vital signs are unreliable in geriatric blunt trauma victims.

BACKGROUND: Normal vital signs are typically associated with improved outcomes in trauma patients. Whether this association is true for geriatric patients is unclear. METHODS: A Level 1 trauma center retrospective chart review of vital signs on presentation (heart rate [HR] and blood pressure) in young (aged 17-35 years) and geriatric (aged 65 years or older) blunt trauma victims from September 2003 to September 2008 was preformed. Generalized nonlinear using piecewise regression for the linear portion of standard logistic models was used to model risk of mortality as a function of HR and blood pressure. Independent models were selected for elderly and young trauma patients based on blood pressure and HR. Models of the same complexity were then fit within each gender and age. RESULTS: There were 2,194 geriatric and 2,081 young patients. Two hundred fifty-one (11.4%) geriatric and 49 (2.4%) young patients died. At all points of "normality," the mortality of the geriatric patients was higher than the young group. Mortality increases considerably in the elderly patients for HRs >90 beats per minute (bpm), an association not seen until HR of 130 bpm in the young group. Mortality significantly increases with systolic blood pressure (SBP) <110 mm Hg in the geriatric patients but not until a SBP of 95 mm Hg in the young patients. HR and mortality association was most variable in the male geriatric patients. CONCLUSIONS: Vital signs on presentation are less predictive of mortality in geriatric blunt trauma victims. Geriatric blunt trauma patients warrant increased vigilance despite normal vital signs on presentation. New trauma triage set points of HR >90 or SBP <110 mm Hg should be considered in the geriatric blunt trauma patients.

The multiply injured trauma patient: resuscitation, rehabilitation, recovery.

The care of the acutely injured patient requires a multidisciplinary approach from the moment of injury through rehabilitation and reintegration into society. In addition to the doctors and nurses providing many aspects of the acute and chronic medical care, the rehabilitation component is delivered by several skilled specialists focused on maximizing functional outcomes.

The evolution of the Rhode Island trauma system: where do we stand?

The Rhode Island Trauma System today has been shown to demonstrate several positive attributes in the delivery of patient care; however, ongoing efforts need to continue in the realms of field and inter-facility communication, efficiency in inter-hospital transfer, and rehabilitation services. Through ongoing dialogue and the fundamental desire to improve, it remains our goal to provide patients the best care possible during one of the most stressful times of their lives.
