What Happens on Call Doesn't Stay on Call. The Effects of In-house Call on Acute Care Surgeons' Sleep and Burnout: Results of the Surgeon Performance (SuPer) Trial.

OBJECTIVE: We sought to quantify the effects of in-house call(IHC) on sleep patterns and burnout among acute care surgeons (ACS). BACKGROUND: Many ACS take INC, which leads to disrupted sleep and high levels of stress and burnout. METHODS: Physiological and survey data of 224 ACS with IHC were collected over 6 months. Participants continuously wore a physiological tracking device and responded to daily electronic surveys. Daily surveys captured work and life events as well as feelings of restfulness and burnout. The Maslach Burnout Inventory (MBI) was administered at the beginning and end of the study period. RESULTS: Physiological data were recorded for 34,135 days, which includes 4389 nights of IHC. Feelings of moderate, very, or extreme burnout occurred 25.7% of days and feelings of being moderately, slightly, or not at all rested occurred 75.91% of days. Decreased amount of time since the last IHC, reduced sleep duration, being on call, and having a bad outcome all contribute to greater feelings of daily burnout ( P <0.001). Decreased time since last call also exacerbates the negative effect of IHC on burnout ( P <0.01). CONCLUSIONS: ACS exhibit lower quality and reduced amount of sleep compared with an age-matched population. Furthermore, reduced sleep and decreased time since the last call led to increased feelings of daily burnout, accumulating in emotional exhaustion as measured on the MBI. A reevaluation of IHC requirements and patterns as well as identification of countermeasures to restore homeostatic wellness in ACS is essential to protect and optimize our workforce.

Assessment of Discharge Analgesic Prescription Patterns for Hospitalized Patients With Rib Fractures.

INTRODUCTION: There is a paucity of data describing opioid prescribing patterns for trauma patients. We investigated pain medication regimens prescribed at discharge for patients with traumatic rib fractures, as well as potential variables predictive of opioid prescribing. METHODS: A single-center, retrospective analysis was performed of 337 adult patients presenting with ≥1 traumatic rib fractures between January and December 2019. The primary outcome was oral morphine milligram equivalents (MME) prescribed on discharge. A multivariable logistic regression analysis was performed to determine factors independently associated with above median (150) MME prescription at discharge. RESULTS: The majority of patients were male (68.8%) with a median age of 53 y. Blunt trauma accounted for 97.3% of cases with a median Injury Severity Score(ISS) of 10. Locoregional pain procedures were utilized in 16.9% of patients. Opioids were the most common analgesic prescribed at discharge, and 74.1% of patients prescribed opioids on discharge were also prescribed a non-opioid adjunct. On multivariable analysis, daily MME prescribed during hospitalization (OR 1.01, 95% CI 1.01-1.02, P < 0.01) and number of rib fractures (OR 2.26, 95% CI 1.36-3.74, P < 0.01) were predictive of high MME prescribed on discharge. CONCLUSIONS: For patients with traumatic rib fractures, daily MME during hospitalization and number of rib fractures were predictive of high MME prescribing on discharge. Further prospective studies evaluating strategies for pain management and protocolized approaches to opioid prescribing are needed to reduce unnecessary and inappropriate opioid use in this patient population.

Sensing global changes in local patterns of energy consumption in cities during the early stages of the COVID-19 pandemic.

COVID-19, and the wider social and economic impacts that a global pandemic entails, led to unprecedented reductions in energy consumption globally. Whilst estimates of changes in energy consumption have emerged at the national scale, detailed sub-regional estimates to allow for global comparisons are less developed. Using night-time light satellite imagery from December 2019-June 2020 across 50 of the world's largest urban conurbations, we provide high resolution estimates (450 m2) of spatio-temporal changes in urban energy consumption in response to COVID-19. Contextualising this imagery with modelling based on indicators of mobility, stringency of government response, and COVID-19 rates, we provide novel insights into the potential drivers of changes in urban energy consumption during a global pandemic. Our results highlight the diversity of changes in energy consumption between and within cities in response to COVID-19, moderating dominant narratives of a shift in energy demand away from dense urban areas. Further modelling highlights how the stringency of the government's response to COVID-19 is likely a defining factor in shaping resultant reductions in urban energy consumption.

The Successful Treatment of Elephantiasis Nostras Verrucosa With Ablative Carbon Dioxide Laser.

BACKGROUND AND OBJECTIVE: Elephantiasis nostras verrucosa (ENV) is a disfiguring skin condition that is difficult to treat. Existing treatment modalities serve to improve cosmesis or treat symptoms. Herein, we report a case of ENV with lymphocutaneous fistula successfully treated with ablative carbon dioxide laser. STUDY DESIGN/PATIENTS AND METHODS: A 57-year-old woman with biopsy-proven ENV with lymphocutaneous fistula was treated with ablative carbon dioxide laser to the symptomatic area of her right thigh in 3 treatment sessions over 6 months. RESULTS: The patient had resolution of lymphocutaneous drainage as well as 90% improvement in the appearance of ENV lesions at the 1-month follow-up visit. CONCLUSION: Ablative carbon dioxide laser may provide cosmetic, symptomatic, and medical benefit for patients with localized ENV.

DRD2 C957T polymorphism is associated with improved 6-month verbal learning following traumatic brain injury.

Traumatic brain injury (TBI) often leads to heterogeneous clinical outcomes, which may be influenced by genetic variation. A single-nucleotide polymorphism (SNP) in the dopamine D2 receptor (DRD2) may influence cognitive deficits following TBI. However, part of the association with DRD2 has been attributed to genetic variability within the adjacent ankyrin repeat and kinase domain containing 1 protein (ANKK1). Here, we utilize the Transforming Research and Clinical Knowledge in Traumatic Brain Injury Pilot (TRACK-TBI Pilot) study to investigate whether a novel DRD2 C957T polymorphism (rs6277) influences outcome on a cognitive battery at 6 months following TBI-California Verbal Learning Test (CVLT-II), Wechsler Adult Intelligence Test Processing Speed Index Composite Score (WAIS-PSI), and Trail Making Test (TMT). Results in 128 Caucasian subjects show that the rs6277 T-allele associates with better verbal learning and recall on CVLT-II Trials 1-5 (T-allele carrier 52.8 ± 1.3 points, C/C 47.9 ± 1.7 points; mean increase 4.9 points, 95% confidence interval [0.9 to 8.8]; p = 0.018), Short-Delay Free Recall (T-carrier 10.9 ± 0.4 points, C/C 9.7 ± 0.5 points; mean increase 1.2 points [0.1 to 2.5]; p = 0.046), and Long-Delay Free Recall (T-carrier 11.5 ± 0.4 points, C/C 10.2 ± 0.5 points; mean increase 1.3 points [0.1 to 2.5]; p = 0.041) after adjusting for age, education years, Glasgow Coma Scale, presence of acute intracranial pathology on head computed tomography scan, and genotype of the ANKK1 SNP rs1800497 using multivariable regression. No association was found between DRD2 C947T and non-verbal processing speed (WAIS-PSI) or mental flexibility (TMT) at 6 months. Hence, DRD2 C947T (rs6277) may be associated with better performance on select cognitive domains independent of ANKK1 following TBI.

Incidental finding of a true human tail in an adult: a case report.

True human tails are rare vestigial structures that are typically removed in childhood. Here a case is presented in which an inconspicuous sacrococcygeal tail was incidentally discovered in late adulthood. A 56-year-old man with no significant past medical history presented to a dermatology clinic with a chief complaint of a hyperpigmented lesion on his central back. However, on full body skin exam, a separate flesh-colored 0.7 cm × 0.5 cm appendage was discovered in the midline sacrococcygeal region. This lesion had been present and unchanged since childhood. This particular lesion was removed via shave biopsy. Microscopic exam found it to be consistent with a diagnosis of a true human tail. There were no apparent involved spinal cord structures, and no further treatment was thought to be necessary. Human tails are congenital anomalies associated with occult spinal lesions in about 50% of cases. Therefore, it is in these patients' best interest to thoroughly evaluate for spinal cord involvement prior to biopsy. There is a relative lack of literature published on the topic, and a greater awareness of human tails would be helpful to ensure their inclusion in a differential diagnosis for persistent sacrococcygeal lesions in patients of any age.

Temporal profile of care following mild traumatic brain injury: predictors of hospital admission, follow-up referral and six-month outcome.

OBJECTIVE: To investigate the clinical management and medical follow-up of patients with mild traumatic brain injury (mTBI) presenting to emergency departments (EDs). METHODS: Overall, 168 adult patients with mTBI from the prospective, multicentre Transforming Research and Clinical Knowledge in TBI (TRACK-TBI) Pilot study with Glasgow Coma Scale (GCS) 13-15, no polytrauma and alive at six months were included. Predictors for hospital admission, three-month follow-up referral and six-month functional disability (Glasgow Outcome Scale-Extended (GOSE) ≤ 6) were analysed using multivariable regression. RESULTS: Overall, 48% were admitted to hospital, 22% received three-month referral and 27% reported six-month functional disability. Intracranial pathology on ED head computed tomography (multivariable odds ratio (OR) = 81.08, 95% confidence interval (CI) [10.28-639.36]) and amnesia (>30-minutes: OR = 5.27 [1.75-15.87]; unknown duration: OR = 4.43 [1.26-15.62]) predicted hospital admission. Older age (per-year OR = 1.03 [1.01-1.05]) predicted three-month referral, while part-time/unemployment predicted lack of referral (OR = 0.17 [0.06-0.50]). GCS < 15 (OR = 2.46 [1.05-5.78]) and prior history of seizures (OR = 3.62 [1.21-10.89]) predicted six-month functional disability, while increased education (per-year OR = 0.86 [0.76-0.97]) was protective. CONCLUSIONS: Clinical factors modulate triage to admission, while demographic/socioeconomic elements modulate follow-up care acquisition; six-month functional disability associates with both clinical and demographic/socioeconomic variables. Improving triage to acute and outpatient care requires further investigation to optimize resource allocation and outcome after mTBI. ClinicalTrials.gov registration: NCT01565551.

Perioperative morbidity and mortality after lumbar trauma in the elderly.

OBJECT Traumatic fractures of the thoracolumbar spine are common injuries, accounting for approximately 90% of all spinal trauma. Lumbar spine trauma in the elderly is a growing public health problem with relatively little evidence to guide clinical management. The authors sought to characterize the complications, morbidity, and mortality associated with surgical and nonsurgical management in elderly patients with traumatic fractures of the lumbar spine. METHODS Using the National Sample Program of the National Trauma Data Bank, the authors performed a retrospective analysis of patients ≥ 55 years of age who had traumatic fracture to the lumbar spine. This group was divided into middle-aged (55-69 years) and elderly (≥ 70 years) cohorts. Cohorts were subdivided into nonoperative, vertebroplasty or kyphoplasty, noninstrumented surgery, and instrumented surgery. Univariate and multivariable analyses were used to characterize and identify predictors of medical and surgical complications, mortality, hospital length of stay, ICU length of stay, number of days on ventilator, and hospital discharge in each subgroup. Adjusted odds ratios, mean differences, and associated 95% CIs were reported. Statistical significance was assessed at p < 0.05, and the Bonferroni correction for multiple comparisons was applied for each outcome analysis. RESULTS Between 2003 and 2012, 22,835 people met the inclusion criteria, which represents 94,103 incidents nationally. Analyses revealed a similar medical and surgical complication profile between age groups. The most prevalent medical complications were pneumonia (7.0%), acute respiratory distress syndrome (3.6%), and deep venous thrombosis (3%). Surgical site infections occurred in 6.3% of cases. Instrumented surgery was associated with the highest odds of each complication (p < 0.001). The inpatient mortality rate was 6.8% for all subjects. Multivariable analyses demonstrated that age ≥ 70 years was an independent predictor of mortality (OR 3.16, 95% CI 2.77-3.60), whereas instrumented surgery (multivariable OR 0.38, 95% CI 0.28-0.52) and vertebroplasty or kyphoplasty (OR 0.27, 95% CI 0.17-0.45) were associated with decreased odds of death. In surviving patients, both older age (OR 0.32, 95% CI 0.30-0.34) and instrumented fusion (OR 0.37, 95% CI 0.33-0.41) were associated with decreased odds of discharge to home. CONCLUSIONS The present study confirms that lumbar surgery in the elderly is associated with increased morbidity. In particular, instrumented fusion is associated with periprocedural complications, prolonged hospitalization, and a decreased likelihood of being discharged home. However, fusion surgery is also associated with reduced mortality. Age alone should not be an exclusionary factor in identifying surgical candidates for instrumented lumbar spinal fusion. Future studies are needed to confirm these findings.

When concentrated disadvantage happens: Exploring the nexus of energy and internet insecurities among vulnerable households.

Digital divide and energy insecurity are pervasive issues among underserved communities, issues that become prounoued during the COVID-19 lockdowns. These disparities underscore the critical need to address them promptly to narrow socio-economic gaps. Our study, based on an online survey of 2,588 respondents in the United Kingdom, explores how concentrated socio-economic disadvantage exacerbates insecurities relating to energy and internet access. Our findings reveal that marginalized groups including low-income households, women, renters, ethnic minorities, and individuals with lower educational attainment are disproportionately affected. Our research extends beyond financial implications to explore the broader social and psychological effects such as trust in utility and internet providers. The study also demonstrates how heightened burdens from energy and internet costs adversely affect the quality of indoor environments, underscoring the interconnected nature of these challenges. Based on these insights, we advocate for policy interventions that adopt comprehensive social justice frameworks to tackle these intersecting inequalities effectively.

Petitions for Extreme Risk Protection Orders and Second Amendment Sanctuary Status in Colorado.

Importance: Extreme risk protection orders (ERPOs) temporarily bar individuals adjudicated as being at risk of violence (including suicide) from buying or possessing firearms. In protest, many US jurisdictions have declared themselves "Second Amendment sanctuaries" (2A sanctuaries). Many 2A sanctuaries continue to use ERPOs in low numbers, suggesting a poorly defined risk threshold at which they are acceptable. Objective: To characterize circumstances under which ERPOs are used in 2A sanctuaries, highlighting their most broadly acceptable applications. Design, Setting, and Participants: This cross-sectional study of civil court documents analyzed petitions for ERPOs filed in Colorado from January 2020 to December 2022. All petitions during the study period were included following de-duplication. These include petitions filed by law enforcement and family members against adults allegedly at risk of firearm violence across the state. Data were analyzed on a rolling basis between January 2020 and June 2023. Exposure: ERPO petition filed in Colorado. Main Outcomes and Measures: Seventy-seven data elements defined a priori were abstracted from all petitions and case files, including respondent demographics, petitioner types (family or law enforcement), types of threats (self, other, mass violence, combination), violence risk factors, and case outcomes (granted, denied). Results: Of a total 338 ERPOs filed in Colorado, 126 (37.3%) occurred in 2A sanctuaries. Sixty-one of these 2A petitions were granted emergency orders, and 40 were full 1-year ERPOs after a hearing. Forty ERPOs (31.7%) were petitioned for by law enforcement. Petitions in non-2A counties were more likely to have been filed by law enforcement (138 of 227 [64.9%] vs 40 of 126 [31.7%]; P < .001) and to have had an emergency order granted (177 of 227 [78.0%] vs 61 of 126 [48.4%]; P < .001) than in 2A sanctuaries. Qualitative analysis of cases in 2A sanctuaries revealed common aggravating risk characteristics, including respondents experiencing hallucinations, histories of police interaction, and substance misuse. ERPOs have been granted in 2A sanctuaries against individuals threatening all forms of violence we abstracted for (themselves, others, and mass violence). Conclusions and Relevance: In this examination of ERPO petitions across Colorado, more than a third of filings occurred in 2A sanctuaries. Nonetheless, law enforcement represent proportionately fewer petitions in these areas, and petitions are less likely to be granted. Serious mental illness, substance misuse, and prior interactions with law enforcement featured prominently in 2A sanctuary petitions. These case circumstances highlight dangerous situations in which ERPOs are an acceptable risk-prevention tool, even in areas politically predisposed to opposing them.

Home Is Not Always Where the Sleep Is: Effect of Home Call on Sleep, Burnout, and Surgeon Well-Being.

BACKGROUND: In-house calls contribute to loss of sleep and surgeon burnout. Although acknowledged to have an opportunity cost, home call is often considered less onerous, with minimal effects on sleep and burnout. We hypothesized home call would result in impaired sleep and increased burnout in acute care surgeons. STUDY DESIGN: Data from 224 acute care surgeons were collected for 6 months. Participants wore a physiological tracking device and responded to daily surveys. The Maslach Burnout Inventory was administered at the beginning and end of the study. Within-participant analyses were conducted to compare sleep, feelings of restedness, and burnout as a function of home call. RESULTS: One hundred seventy-one surgeons took 3,313 home calls, 52.5% were associated with getting called and 38.5% resulted in a return to the hospital. Home call without calls was associated with 3 minutes of sleep loss (p < 0.01), home call with 1 or more call resulted in a further 14 minutes of sleep loss (p < 0.0001), and home call with a return to the hospital led to an additional 70 minutes of sleep loss (p < 0.0001). All variations of home call resulted in decreased feelings of restedness (p < 0.0001) and increased feelings of daily burnout (p < 0.0001, Fig. 1). CONCLUSIONS: Home call is deleterious to sleep and burnout. Even home call without calls or returns to the hospital is associated with burnout. Internal assessments locally should incorporate frequency of calls and returns to the hospital when creating call schedules. Repeated nights of home call can result in cumulative sleep debt, with adverse effects on health and well-being.

Implementation of Extreme Risk Protection Orders in Colorado from 2020 to 2022: Firearm relinquishment and return and petitioner characteristics.

Introduction: Firearm injury remains a public health problem, with nearly 50,000 firearm-related deaths in the US in 2021. Extreme risk protection orders (ERPOs) are civil restraining orders that intend to reduce firearm deaths by temporarily removing firearms from individuals who are threatening violence to themselves or others. We described ERPO use by petitioner type and implementation including firearm removal. Methods: All ERPO petitions filed in Colorado (1/1/2020-12/31/2022) were analyzed using an established abstraction tool and team-based approach. Case data abstracted from petitions and court documents were analyzed descriptively. Results: Over three years, there were 353 ERPO petitions filed in Colorado. Only 39 % percent of granted petitions had documentation of firearms being relinquished. The average number firearms relinquished was 1.8 with a range of 1 to 31 firearms. One third (37.7 %) of petitions mentioned a mental health issue, 10 % had a renewal request, and half (54.6 %) of petitions were filed by law enforcement (LE). LE petitions filed were more likely to be granted temporary ERPOs (94.3 % vs 35.0 %, p < 0.0001) and full year ERPOs (79.7 % vs 39.3 %, p < 0.0001) compared to non-LE petitions. Conclusion: Results from these analyses shed light on data gaps surrounding ERPO use and implementation. Differences in LE vs others' ERPO outcomes suggest a need for additional research and training. ERPOs' efficacy hinges on removing access to firearms among those at risk, and a lack of documentation limits the ability to evaluate these policies. This suggests a need to standardize reporting to ensure ERPO utilization and impact can be evaluated.Mini abstract: This descriptive study assessed use, implementation and data gaps surrounding Extreme Risk Protection Orders in Colorado.Abbreviations: Extreme risk protection orders (ERPOs) are civil restraining orders that intend to reduce firearm deaths by temporarily removing firearms from individuals who are threatening violence to themselves or others.

An Abdominal Seat Belt Sign is Associated With Similar Incidence of Hollow Viscus Injury but Increased In-Hospital Mortality in Older Adult Trauma Patients: A PCSA Multicenter Study.

BACKGROUND: The abdominal seat belt sign (SBS) is associated with an increased risk of hollow viscus injury (HVI). Older age is associated with worse outcomes in trauma patients. Thus, older trauma patients ≥65 years of age (OTPs) may be at an increased risk of HVI with abdominal SBS. Therefore, we hypothesized an increased incidence of HVI and mortality for OTPs vs younger trauma patients (YTPs) with abdominal SBS. STUDY DESIGN: This post hoc analysis of a multi-institutional, prospective, observational study (8/2020-10/2021) included patients >18 years old with an abdominal SBS who underwent abdominal computed tomography (CT) imaging. Older trauma patients were compared to YTPs (18-64 years old) with bivariate analyses. RESULTS: Of the 754 patients included in this study from nine level-1 trauma centers, there were 110 (14.6%) OTPs and 644 (85.4%) YTPs. Older trauma patients were older (mean 75.3 vs 35.8 years old, P < .01) and had a higher mean Injury Severity Score (10.8 vs 9.0, P = .02). However, YTPs had an increased abdominal abbreviated-injury scale score (2.01 vs 1.63, P = .02). On CT imaging, OTPs less commonly had intraabdominal free fluid (21.7% vs 11.9%, P = .02) despite a similar rate of abdominal soft tissue contusion (P > .05). Older trauma patients also had a statistically similar rate of HVI vs YTPs (5.5% vs 9.8%, P = .15). Despite this, OTPs had increased mortality (5.5% vs 1.1%, P < .01) and length of stay (LOS) (5.9 vs 4.9 days P < .01). CONCLUSION: Despite a similar rate of HVI, OTPs with an abdominal SBS had an increased rate of mortality and LOS. This suggests the need for heightened vigilance when caring for OTPs with abdominal SBS.

Prevalence and Outcomes of High versus Low Ratio Plasma to Red Blood Cell Resuscitation in a Multi-Institutional Cohort of Severely Injured Children.

BACKGROUND: The benefit of targeting high ratio fresh frozen plasma (FFP):red blood cell (RBC) transfusion in pediatric trauma resuscitation is unclear as existing studies are limited to patients who retrospectively met criteria for massive transfusion. The purpose of this study is to evaluate the use of high ratio FFP:RBC transfusion and the association with outcomes in children presenting in shock. METHODS: A post-hoc analysis of a 24-institution prospective observational study (4/2018-9/2019) of injured children <18 years with elevated age-adjusted shock index was performed. Patients transfused within 24 hours were stratified into cohorts of low (<1:2) or high (>1:2) ratio FFP:RBC. Nonparametric Kruskal-Wallis and chi-square were used to compare characteristics and mortality. Competing risks analysis was used to compare extended (≥75th percentile) ventilator, intensive care, and hospital days while accounting for early deaths. RESULTS: Of 135 children with median (IQR) age 10 (5,14) years and weight 40 (20,64) kg, 85 (63%) received low ratio transfusion and 50 (37%) high ratio despite similar activation of institutional massive transfusion protocols (MTP; low-38%, high-46%, p = .34). Most patients sustained blunt injuries (70%). Median injury severity score was greater in high ratio patients (low-25, high-33, p = .01); however, hospital mortality was similar (low-24%, high-20%, p = .65) as was the risk of extended ventilator, ICU, and hospital days (all p > .05). CONCLUSION: Despite increased injury severity, patients who received a high ratio of FFP:RBC had comparable rates of mortality. These data suggest high ratio FFP:RBC resuscitation is not associated with worst outcomes in children who present in shock. MTP activation was not associated with receipt of high ratio transfusion, suggesting variability in MTP between centers. LEVEL OF EVIDENCE: Prospective cohort study, Level II.

Muffins and Meditation: Combatting Burnout in Surgical Residents.

OBJECTIVE: To quantify the prevalence of burnout in our surgical residency program and to assess the impact of a weekly wellness program for surgical residents through validated tools measuring mindfulness, self-compassion, flourishing, and burnout. Our hypothesis was that participants with more frequent attendance would: (1) be more mindful and self-compassionate and (2) experience less burnout and more flourishing. DESIGN: An optional one-hour weekly breakfast conference was facilitated by a senior surgical faculty member with the time protected from all clinical duties. Following a guided meditation, participants were given time for reflection and dialogue about their training experiences or led in a wellness exercise. TRANCE (tolerance, respect, anonymity, nonretaliation, compassion, egalitarianism) principles were utilized to create a safe and open environment. Residents were surveyed at the end of the study period, which was from March 2017 through June 2018. SETTING: The conference and data analysis was conducted at Denver Health Medical Center, affiliated with the University of Colorado School of Medicine. PARTICIPANTS: This study analyzed survey responses from 85 surgical residents. RESULTS: Following the wellness program, when answering the 2-question Maslach Burnout Inventory, 35.7% of residents reported feeling burned out by their work once a week or more, and 29.7% reported feeling more callous toward people once a week or more. After multivariate analysis, the only independent predictors of increased burnout were "not being married or in a committed relationship," lower positive affect, and higher negative affect. Written feedback was overwhelmingly positive, and residents expressed gratitude for the conference, the opportunity for self-reflection, and open dialogue with attendings and colleagues. CONCLUSIONS: The prevalence of burnout is high among surgical residents. Allowing time to practice a mindfulness meditation while providing space for residents to share their experiences may be protective, and efforts should be made to reduce barriers to participation.

Development and Validation of a Novel Hollow Viscus Injury Prediction Score for Abdominal Seatbelt Sign: A Pacific Coast Surgical Association Multicenter Study.

BACKGROUND: High-quality CT can exclude hollow viscus injury (HVI) in patients with abdominal seatbelt sign (SBS) but performs poorly at identifying HVI. Delay in diagnosis of HVI has significant consequences necessitating timely identification. STUDY DESIGN: This multicenter, prospective observational study conducted at 9 trauma centers between August 2020 and October 2021 included adult trauma patients with abdominal SBS who underwent abdominal CT before surgery. HVI was determined intraoperatively and physiologic, examination, laboratory, and imaging findings were collected. Least absolute shrinkage and selection operator- and probit regression-selected predictor variables and coefficients were used to assign integer points for the HVI score. Validation was performed by comparing the area under receiver operating curves (AUROC). RESULTS: Analysis included 473 in the development set and 203 in the validation set. The HVI score includes initial systolic blood pressure <110 mmHg, abdominal tenderness, guarding, and select abdominal CT findings. The derivation set has an AUROC of 0.96, and the validation set has an AUROC of 0.91. The HVI score ranges from 0 to 17 with score 0 to 5 having an HVI risk of 0.03% to 5.36%, 6 to 9 having a risk of 10.65% to 44.1%, and 10 to 17 having a risk of 58.59% to 99.72%. CONCLUSIONS: This multicenter study developed and validated a novel HVI score incorporating readily available physiologic, examination, and CT findings to risk stratify patients with an abdominal SBS. The HVI score can be used to guide decisions regarding management of a patient with an abdominal SBS and suspected HVI.

Crystalloid volume is associated with short-term morbidity in children with severe traumatic brain injury: An Eastern Association for the Surgery of Trauma multicenter trial post hoc analysis.

OBJECTIVE: This study examined differences in clinical and resuscitation characteristics between injured children with and without severe traumatic brain injury (sTBI) and aimed to identify resuscitation characteristics associated with improved outcomes following sTBI. METHODS: This is a post hoc analysis of a prospective observational study of injured children younger than 18 years (2018-2019) transported from the scene, with elevated shock index pediatric-adjusted on arrival and head Abbreviated Injury Scale score of ≥3. Timing and volume of resuscitation products were assessed using χ 2t test, Fisher's exact t test, Kruskal-Wallis, and multivariable logistic regression analyses. RESULTS: There were 142 patients with sTBI and 547 with non-sTBI injuries. Severe traumatic brain injury patients had lower initial hemoglobin (11.3 vs. 12.4, p < 0.001), greater initial international normalized ratio (1.4 vs. 1.1, p < 0.001), greater Injury Severity Score (25 vs. 5, p < 0.001), greater rates of ventilator (59% vs. 11%, p < 0.001) and intensive care unit (ICU) requirement (79% vs. 27%, p < 0.001), and more inpatient complications (18% vs. 3.3%, p < 0.001). Severe traumatic brain injury patients received more prehospital crystalloid (25% vs. 15%, p = 0.008), ≥1 crystalloid boluses (52% vs. 24%, p < 0.001), and blood transfusion (44% vs. 12%, p < 0.001) than non-sTBI patients. Among sTBI patients, receipt of ≥1 crystalloid bolus (n = 75) was associated with greater ICU need (92% vs. 64%, p < 0.001), longer median ICU (6 vs. 4 days, p = 0.027) and hospital stay (9 vs. 4 days, p < 0.001), and more in-hospital complications (31% vs. 7.5%, p = 0.003) than those who received <1 bolus (n = 67). These findings persisted after adjustment for Injury Severity Score (odds ratio, 3.4-4.4; all p < 0.010). CONCLUSION: Pediatric trauma patients with sTBI received more crystalloid than those without sTBI despite having a greater international normalized ratio at presentation and more frequently requiring blood products. Excessive crystalloid may be associated with worsened outcomes, including in-hospital mortality, seen among pediatric sTBI patients who received ≥1 crystalloid bolus. Further attention to a crystalloid sparing, early transfusion approach to resuscitation of children with sTBI is needed. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Earlier liposomal bupivacaine blocks improve analgesia and decrease opioid requirements for bariatric surgery patients.

INTRODUCTION: Optimal timing of liposomal bupivacaine (LB) transversus abdominis plane (TAP) blocks for bariatric surgery is unknown. We hypothesize that LB TAPs used prior to incision decrease narcotic requirements compared to the completion of surgery. METHODS: Single intuition review of 86 bariatric surgery patients who received LB TAP blocks from 2/2019 through 8/2020. 44 patients received LB at the beginning of the case (Beg) while 42 patients received LB at the completion (End). Morphine equivalent daily doses (MEDD) were compared. RESULTS: MEDD requirements for the Beg-LB group compared to the End-LB group were significantly less on POD 0 (4.8 vs 6.8 MEDD, p = 0.01) and POD 2 (16 vs 32, p = 0.04). Discharge oxycodone prescriptions were lower in the Beg-LB group (15 vs 20, p = 0.008). CONCLUSIONS: Patients who received LB TAP blocks prior to bariatric surgery required fewer narcotics than patients who received the LB TAP at the conclusion of surgery.

Sustainability of Palliative Care Principles in the Surgical Intensive Care Unit Using a Multi-Faceted Integration Model.

Objective(s): Understanding patient goals of care is essential in any setting, and especially so in an urban, safety net trauma centers' Surgical Intensive Care Units (SICU). This underscores the need for implementation of palliative care principles and practices, such as identification of surrogate decision makers, goals-of-care discussions, and CPR directives, in the SICU. Methods: A pragmatic, quality improvement study utilizing a retrospective, pre- and post-intervention continuum analysis. Interventions included a surgeon champion, resident education, and an electronic medical record template, called the Advanced Care Planning (ACP) Note, for use on daily rounds. We reviewed the charts of all adults admitted to the SICU before, during, and after these interventions to identify the incidence of surrogate decision maker documentation by SICU residents. Results: There was an early and enthusiastic adoption in ACP note utilization by SICU residents over the study period. Rates of documenting surrogate decision makers increased throughout the study period (p < 0.0001). Having an ACP note in the chart was associated with significantly higher rates of documented surrogate decision makers (p < 0.0001). Conclusions: Through the integration of targeted education, standardization of an electronic medical record tool for palliative care documentation, and incorporation of palliative care goals into daily rounding ICU checklists, we significantly increased identification of surrogate decision makers in the SICU of our urban Level One trauma center. Chart review from one year post-intervention showed sustained commitment to the use of the ACP note and identification of surrogate decision makers.
