To the point: Utility of laparoscopy for operative management of stabbing abdominal trauma. Am J Surg 2024; 231:125-131. [PMID: 38309996 DOI: 10.1016/j.amjsurg.2024.01.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 12/20/2023] [Accepted: 01/24/2024] [Indexed: 02/05/2024]
Abstract
BACKGROUND Algorithms for managing penetrating abdominal trauma are conflicting or vague regarding the role of laparoscopy. We hypothesized that laparoscopy is underutilized among hemodynamically stable patients with abdominal stab wounds. METHODS Trauma Quality Improvement Program data (2016-2019) were used to identify stable (SBP ≥110 and GCS ≥13) patients ≥16yrs with stab wounds and an abdominal procedure within 24hr of admission. Patients with a non-abdominal AIS ≥3 or missing outcome information were excluded. Patients were analyzed based on index procedure approach: open, therapeutic laparoscopy (LAP), or LAP-conversion to open (LCO). Center, clinical characteristics and outcomes were compared according to surgical approach and abdominal AIS using non-parametric analysis. RESULTS 5984 patients met inclusion criteria with 7 % and 8 % receiving therapeutic LAP and LCO, respectively. The conversion rate for patients initially treated with LAP was 54 %. Compared to conversion or open, therapeutic LAP patients had better outcomes including shorter ICU and hospital stays and less infection complications, but were younger and less injured. Assessing by abdominal AIS eliminated ISS differences, meanwhile LAP patients still had shorter hospital stays. At time of admission, 45 % of open patients met criteria for initial LAP opportunity as indicated by comparable clinical presentation as therapeutic laparoscopy patients. CONCLUSIONS In hemodynamically stable patients, laparoscopy remains infrequently utilized despite its increasing inclusion in current guidelines. Additional opportunity exists for therapeutic laparoscopy in trauma, which appears to be a viable alternative to open surgery for select injuries from abdominal stab wounds.

Lessons for the next pandemic: analysis of the timing and outcomes including post-discharge decannulation rates for tracheostomy in severe COVID-19 respiratory failure. Eur J Trauma Emerg Surg 2024; 50:581-590. [PMID: 38349397 DOI: 10.1007/s00068-024-02444-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2023] [Accepted: 12/31/2023] [Indexed: 04/23/2024]
Abstract
PURPOSE COVID-19 patients with respiratory failure frequently require prolonged ventilatory support that would typically warrant early tracheostomy. There has been significant debate on timing, outcomes, and safety of these procedures. The purpose of this study was to determine the epidemiological, hospital, and post-discharge outcomes of this cohort, based on early (ET) versus late (LT) tracheostomy. METHODS Retrospective review (March 2020-January 2021) in a 5-hospital system of ventilated patients who underwent tracheostomy. Demographics, hospital/ICU length of stay (LOS), procedural characteristics, APACHE II scores at ICU admission, stabilization markers, and discharge outcomes were analyzed. Long-term decannulation rates were obtained from long-term acute care facility (LTAC) data. RESULTS A total of 97 patients underwent tracheostomy (mean 61 years, 62% male, 64% Hispanic). Despite ET being frequently performed during active COVID infection (85% vs. 64%), there were no differences in complication types or rates versus LT. APACHE II scores at ICU admission were comparable for both groups; however, > 50% of LT patients met PEEP stability at tracheostomy. ET was associated with significantly shorter ICU and hospital LOS, ventilator days, and higher decannulation rates. Of the cohort discharged to an LTAC, 59% were ultimately decannulated, 36% were discharged home, and 41% were discharged to a skilled nursing facility. CONCLUSIONS We report the first comprehensive analysis of ET and LT that includes LTAC outcomes and stabilization markers in relation to the tracheostomy. ET was associated with improved clinical outcomes and a short LOS, specifically on days of pre-tracheostomy ventilation and in-hospital decannulation rates.

Two-center analysis of cannabis on venous thromboembolism risk after traumatic injury: A matched analysis. Am J Surg 2024:S0002-9610(24)00192-2. [PMID: 38582739 DOI: 10.1016/j.amjsurg.2024.03.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 02/22/2024] [Accepted: 03/25/2024] [Indexed: 04/08/2024]
Abstract
BACKGROUND Conflicting evidence exists evaluating associations between cannabis (THC) and post-traumatic DVT. METHODS Retrospective analysis (2014-2023) of patients ≥15yrs from two Level I trauma centers with robust VTE surveillance and prophylaxis protocols. Multivariable hierarchical regression assessed the association between THC and DVT risk. THC + patients were direct matched to other drug use categories on VTE risk markers and hospital length of stay. RESULTS Of 7365 patients, 3719 were drug-, 575 were THC + only, 2583 were other drug+, and 488 were TCH+/other drug+. DVT rates by exposure group did not differ. TCH + only patients had higher GCS scores, shorter hospital length of stay, and the lowest pelvic fracture and mortality rates. A total of 458 drug-, 453 other drug+, and 232 THC+/other drug + patients were matched to 458, 453, and 232 THC + only patients. There were no differences in DVT event rates in any paired sub-cohort set. Additionally, iteratively adjusted paired models did not show an association between THC and DVT. CONCLUSIONS THC does not appear to be associated with increased DVT risk in patients with strict trauma chemoprophylaxis. Toxicology testing is useful for identifying substance abuse intervention opportunities, but not for DVT risk stratification in THC + patients.

A Comparative Study of Laparoscopic versus Open Management of Index Small Bowel Obstruction in Children. J Pediatr Surg 2024; 59:416-420. [PMID: 37978001 DOI: 10.1016/j.jpedsurg.2023.10.043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Accepted: 10/18/2023] [Indexed: 11/19/2023]
Abstract
INTRODUCTION There is limited literature on the optimal approach to treat adhesive small bowel obstruction (ASBO) in children. We sought to compare rates and outcomes of laparoscopic (LAP) and open (OPEN) surgery for pediatric ASBO. METHODS A California statewide database was used to identify children (<18 years old) with an index ASBO from 2007 to 2020. The primary outcome was the type of operative management: LAP or OPEN. Secondary outcomes were hospital characteristics, patient demographics, and postoperative complications. We excluded patients treated non-operatively. RESULTS Our study group had 545 patients. 381 (70%) underwent OPEN and 164 (30%) LAP during the index admission. Over the study period, there was increasing use of laparoscopic surgery, with higher use in older children (p < 0.001). LAP was associated with fewer overall complications (65.2% vs. 81.6%, p < 0.001), with a decreasing trend in complications over time (p < 0.001). The LAP group had significantly lower rates of bowel resection (4.9% vs. 17.1%, p < 0.001), length of stay (LOS) (17 vs. 23 days, p < 0.001), and TPN use (12.2% vs. 29.1%, p < 0.001). Mortality rates were equivalent. Although the LAP group had lower readmission rates (22.6% vs. 37.3%, p < 0.001), the length of time between discharge and readmission was similar (171 vs. 165 days, p = 0.190). DISCUSSION The use of laparoscopic surgery for index ASBO increased over the study period. However, it was less commonly utilized in younger children. LAP had fewer overall complications as well as shorter LOS, decreased TPN use, and fewer readmissions. The benefits and risks of each approach must be weighed. LEVEL OF EVIDENCE III.

Abstract
INTRODUCTION The Brain Injury Guidelines (BIG) stratify patients by traumatic brain injury (TBI) severity to provide management recommendations to reduce health care resource burden but mandates that patients on anticoagulation (AC) are allocated to the most severe tertile (BIG 3). We sought to analyze TBI patients on AC therapy using a modified BIG model to determine if this population can offer further opportunity for safe reductions in health care resource utilization. METHODS Patients 55 years or older on AC with traumatic intracranial hemorrhage (ICH) from two centers were retrospectively stratified into BIG 1 to 3 risk groups using modified BIG criteria excluding AC as a criterion. Intracranial hemorrhage progression, neurosurgical intervention (NSI), death, and worsened discharge status were compared. RESULTS A total of 221 patients were included, with 23%, 29%, and 48% classified as BIG 1, BIG 2, and BIG 3, respectively. The BIG 3 cohort had a higher rate of AC reversal agents administered (66%) compared with the BIG 1 (40%) and BIG 2 (54%) cohorts ( p < 0.01), as well as ICH progression discovered on repeat head computed tomography (56% vs. 38% vs. 26%, respectively; p < 0.001). No patients in the BIG 1 and 2 cohorts required NSI. No patients in BIG 1 and 3% of patients in BIG 2 died secondary to the ICH. In the BIG 3 cohort, 16% of patients required NSI and 26% died. Brain Injury Guidelines 3 patients had 15 times the odds of mortality compared with BIG 1 patients ( p < 0.01). CONCLUSION The AC population had higher rates of ICH progression than the BIG literature, but this did not lead to more NSI or mortality in the lower tertiles of our modified BIG protocol. If the modified BIG used the original tertile management on our population, then NS consultation may have been reduced by up to 52%. These modified criteria may be a safe opportunity for further health care resource and cost savings in the TBI population. LEVEL OF EVIDENCE Prognostic and Epidemiological; Level IV.

Abstract
INTRODUCTION To examine practice patterns and surgical outcomes of nonoperative versus operative management (OPM) of children presenting with an index adhesive small bowel obstruction (ASBO). METHODS A California statewide health discharge database was used to identify children (<18 y old) with an index ASBO from 2007 to 2020. The primary study outcome was evaluating initial management patterns (nonoperative versus OPM and early [≤3 d] versus late surgery [>3 d]) of ASBO. Secondary outcomes were hospital characteristics, patient demographics, and postoperative complications. RESULTS Of the 2297 patients identified, 1948 (85%) underwent OPM for ASBO during the index admission. Of these, 14.7% underwent early surgery within 3 d. Teaching hospitals had higher operative intervention than nonteaching centers (87.1% versus 83.7%, P = 0.034). OPM was the highest in 0-5-year-olds compared to other ages (89% versus 82%, P < 0.001). In comparison to early surgery, late surgery was associated with longer length of stay (early 7[interquartile range 5-10], late 9[interquartile range 6-17], P < 0.001), increased infectious complications (16.4% versus 9.8%, P = 0.004), and greater use of total parenteral nutrition (28.0% versus 14.3%, P = 0.001); there was no difference in bowel resection (21% versus 18%, P = 0.102) or mortality (P = 0.423). CONCLUSIONS Our pediatric study demonstrated a high rate of OPM for index ASBO, especially in newborns and toddlers. Although operative intervention, especially late surgery, was associated with increased length of stay, increased infectious complications, and increased total parenteral nutrition use, the rates of bowel resection and mortality did not differ by management strategy. These trends need to be further evaluated to optimize outcomes.

Abstract
BACKGROUND Firearm violence has increased nationwide, with recent surges linked to the COVID-19 pandemic. We measured traumatic assault trends at our urban Level I trauma center and assessed rates of firearm violence over time and pre/post local COVID-19 lockdown based on levels of socioeconomic disadvantage. METHODS We conducted a retrospective review (2016-2022) of assault patients 16 years and older. Demographics and hospital outcomes were assessed by assault mechanism (firearm, knife, blunt). Patient address was correlated to Area Deprivation Index (ADI), a measure of socioeconomic disadvantage. COVID-19 lockdown onset was defined as initial date of lockdown (3/19/2020). Trend and time-series analyses compared all assault mechanisms and firearm-specific assaults pre/post-lockdown. Poisson regression assessed firearm assault risk. RESULTS Of the 1583 total assaults, firearm patients (n = 335) were younger (median 29 years), had longer hospital stays (median 2 days), and greater mortality (12%) than other mechanisms. The 2 years post-lockdown had significantly more firearm assaults (27% vs 15% pre-lockdown, P < .001) and time-series analysis found this abrupt and significant increase in firearm assaults occurred at lockdown onset (P = .01). Also post-lockdown, the rate of firearm assaults increased by 10% for every unit increase in socioeconomic deprivation (P < .01). There was no change in assault type by race/ethnicity. DISCUSSION Firearm assaults increased dramatically immediately post-COVID lockdown at our center and have maintained higher rates through 2022. Greater ADI was associated with increasing firearm assaults and has magnified post-lockdown, demonstrating lower socioeconomic groups are disproportionately and increasingly affected by firearm violence.

Abstract
INTRODUCTION We analyzed the impact of treating center designation and case volume of penetrating trauma on outcomes after pediatric penetrating thoracic injuries (PTI). METHODS PTI patients <18 years were identified from the National Trauma Data Bank (2013-2016). Centers were categorized by type (Pediatric or Adult) and designation status (Level I, Level II, and other). Performance was calculated as the difference between observed and expected mortality and standardized using the total penetrating trauma volume per center. Expected mortality was calculated using the Trauma Mortality Prediction Model. Pearson correlation and linear mixed-effects models evaluated the association between variables and performance. RESULTS We identified 4,134 PTI patients treated at 596 trauma centers: 879 (21%) at Adult Level I, 608 (15%) at Adult Level II, 531 (13%) at Pediatric Level I, 320 (8%) at Pediatric Level II, and 1,796 (43%) at other centers. Primary injury mechanisms were firearm-related (58%) and cut/piercing (42%). Overall mortality was 16% and median predicted mortality was 3.6% (IQR: 1.5% - 11.2%). Among patients with thoracic firearm-related injuries, centers with lower penetrating case volume and total trauma care demonstrated significantly worse outcomes. Multivariable analysis revealed Adult Level I centers had superior outcomes compared with all other non-Level I centers. There was no difference in mortality between Pediatric and Adult Level I centers. DISCUSSION Adult Level I trauma center designation and annual case volume of penetrating thoracic trauma are associated with improved mortality after pediatric firearm-related thoracic injuries. Further study is needed to identify factors in higher volume centers that improve outcomes. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Trauma patients are resource intensive, requiring a variety of medical and procedural interventions during hospitalization. These expenses often label trauma care as "high cost" based on gross hospital charges. We hypothesized that a financial metric built on actual costs and clinically relevant trauma patient cohorts would demonstrate a lower true cost of trauma care than the standardly reported gross hospital charges. METHODS We examined all trauma patients (≥16 yr) treated in 2017 from a single institution and matched them to the institution's detailed financial accounting data. The organization's Financial Operations Division is uniquely able to allocate total operating costs across patient encounters to include medications, procedures, and salaries/fees from medical professionals and administrators. Patient subgroups were identified by Trauma Quality Improvement Program (TQIP) criteria for cost comparisons. RESULTS Overall median cost per patient was $6,544 [IQR $4,975-14,532] for 2,548 patients. The median cost per patient increased with Injury Severity Score (ISS) ranging from $5,457(ISS ≤ 7) to $34,898(ISS ≥ 21), each accompanied by an average 548% increase in gross charges. Costs also varied widely from $13,498 [IQR $8,247-26,254] to $45,759 [IQR $22,186-113,993] across TQIP patient cohorts. Of the total cost, 91% was attributed to personnel alone. DISCUSSION Measuring the true cost of trauma care is feasible. As hypothesized, the true cost of trauma care is lower than charges. True cost increased with injury severity with variable cost across subgroups. Non-physician staff and administration are the largest component of the cost of trauma care.

Abstract
BACKGROUND Orbital fractures represent one of the most common trauma-related facial fractures and may present with a variety of concomitant injuries. Many factors including age, associated diagnoses, and fracture complications are important in determining surgical candidacy. We used a statewide database to determine the prevalence of orbital fractures, rates of surgical repair during initial admission, and early patient outcomes. METHODS A longitudinal analysis of patients with orbital fracture was performed using California's Office of Statewide Health Planning and Development patient discharge database for admissions occurring between January 2015 and December 2018.Patients were identified using International Classification of Diseases, Tenth Revision codes. The primary risk factor was surgical management of orbital fractures. The primary outcomes of interest were readmission requiring surgical management and complications of the fracture. Survival models were developed to evaluate the risk of a repair at readmission adjusting for relevant covariates. RESULTS Of the 67,408 facial fractures included in our study, 8.7% (n = 5872) were diagnosed with orbital fractures. Among this population, 18.4% (n = 1082) underwent surgical repair during their initial admission. Patients were primarily male (71.1%; n = 4,173) and presented in a nonurgent fashion (93.7%; n = 5501). Less than half (42.8%) of patients with an urgent presentation and 16.8% of patients with a nonurgent presentation underwent repair. Centers of Medicaid & Medicare Services guidelines dictated presentation classification. Repair was associated with a significantly higher survival outcome. Orbital fractures were more frequently repaired in the setting of concomitant zygomatic, nasal, and LeFort I-III fractures. Increased risk in complications was observed in all concomitant fracture groups, and there existed a decreased risk of postsurgical complications in these same cohorts. CONCLUSIONS Although most orbital fractures were managed nonoperatively, our analysis found that rates of repair for orbital floor, maxillary, and zygomatic fractures were greater than for other facial fractures. Concomitant fractures were associated with an increased hazard ratio for complications. Although low in prevalence overall, the most often observed postoperative complications in this population were diplopia, glaucoma, and blindness/low vision.

Abstract
PURPOSE The impact of academic publications is often characterized by the total number of future citations. However, this metric does not adequately characterize the true impact in terms of changing practices or paradigms. A new metric called the "disruption score" (DS) has been developed and validated in nonsurgical publications. This study aims to use the DS to identify the most disruptive publications in plastic surgery.The DS, a ratio of 2 numbers, varies between -1 and +1. Scores closer to -1 are developing papers that summarize the known literature while papers closer to +1 are disruptive-they result in a paradigm shift in the field of study. METHODS A search was performed for all articles from 1954 to 2014 in the following journals: Plastic and Reconstructive Surgery; Aesthetic Surgery Journal; Journal of Plastic, Reconstructive, and Aesthetic Surgery; Annals of Plastic Surgery; Aesthetic Plastic Surgery; Clinics in Plastic Surgery; and Plastic Surgery. The disruptive score was calculated for each article.The top 100 papers ranked by DS were examined and any editorials/viewpoints, publications with less than 26 citations, or less than 3 references were excluded because of their subjective nature and smaller academic contribution. The remaining 64 publications were analyzed for topic, study type, and citation count. RESULTS A total of 32,622 articles were found with a DS range from 0.385 to 0.923. The mean score of the top 64 articles was 0.539 with an average citation count of 195 and 9 references. Plastic and Reconstructive Surgery had the most disruptive papers with 50. There were no randomized controlled trials with a majority of the studies being technical descriptions or case series. CONCLUSIONS There are many ways to measure academic success, but there are fewer ways to measure the impact of academic contributions. The DS is a novel measurement that can demonstrate when an article results in a paradigm shift as opposed to just total citation count. When applied to the plastic surgery literature, the DS demonstrates that technical innovation and creativity are the most academically impactful. Future evaluations of academic success should include the DS to measure the quality of academic contributions.

Abstract
BACKGROUND The relationship between surgical management of adhesive small bowel obstruction (ASBO) and hospital teaching status is not well known. We sought to elucidate the association between hospital teaching status and clinical metrics for ASBO. METHODS Using the 2007-2017 California Office of Statewide Health Planning and Development database, we identified adult ASBO patients hospitalized for surgical intervention. Hospital teaching status was categorized as major teaching (MajT), minor teaching (MinT), and non-teaching (NT). Cox proportional hazards modeling was used to evaluate risk of death and other adverse outcomes. RESULTS Of 25,047 admissions, 15.4% were at MajT, 32.0% at MinT, and 52.6% at NT; 2.9% died. Patients at MajT had longer overall hospital stays (HLOS) than those at MinT or NT (median days 9 vs. 8 vs. 8; p = 0.005), longer post-ASBO procedure HLOS (median days 7 vs. 6 vs. 6; p = 0.0001) and higher rates of small bowel resection (27.1% vs. 21.7% vs. 21.7%; p < 0.0001). Mean time to first surgery at MajT was 3.3 days compared with 2.6 days (p = 0.004) at MinT and NT. Compared with patients at NT, those at MajT were significantly less likely to die (HR 0.62, p < 0.0001), develop pneumonia (HR 0.57, p = 0.001), or experience adverse discharge disposition (HR 0.79, p < 0.0001). CONCLUSION Mortality and morbidity of ASBO surgery were reduced at MajT; however, time to surgery, HLOS, and rate of small bowel resection were greater. These findings may guide improvements in the management of ASBO patients.

Abstract
BACKGROUND Trauma care is associated with unplanned readmissions, which may occur at facilities other than the index treatment facility. This "fragmentation of care" may be associated with adverse outcomes. We evaluated a statewide database that includes readmissions to analyze the incidence and impact of FC. METHODS The California Office of Statewide Health Planning and Development patient discharge data set was evaluated for calendar years 2016 to 2018. Patients 15 years or older diagnosed with blunt abdominal solid organ injury during the index admission were identified. Readmissions were evaluated postdischarge at 1, 3, and 6 months. Patients readmitted within 6 months to a facility other than the index admission facility (fragmented care [FC]) were compared with those readmitted to their index admission facility (non-FC). Logistic regression modeling was used to evaluate risk of FC. RESULTS Of the total 1,580 patients, there were 752 FC (47.6%) and 828 (52.4%) non-FC. Readmissions representing FC at months 1, 3, and 6 were 40.3%, 49.3%, and 53.4%, respectively. At index admission, the groups were demographically and clinically similar, with similar rates of abdominal operations and complications. Non-FC patients had a higher rate of abdominal reoperation at readmission (5.8% non-FC vs. 2.9% FC, p = 0.006). In an adjusted model, multiple readmissions (odds ratio [OR] 1.11, p = 0.014), readmission >30 days after index facility discharge (OR, 1.98; p < 0.001), and discharge to a nonmedical facility (OR, 2.46; p < 0.0001) were associated with increased odds of FC. Operative intervention at index admission was associated with lower odds of FC (OR, 0.77; p = 0.039). However, FC was not independently associated with demographic or insurance characteristics. CONCLUSION The rate of FC among patients with blunt abdominal injury is high. The risk of FC is mitigated when patients are managed operatively during the index admission. Trauma systems should implement measures to ensure that these patients are followed postdischarge. LEVEL OF EVIDENCE Prognostic and epidemiological, level III; Care management, level IV.

Abstract
BACKGROUND Low-molecular-weight heparin (LMWH) is widely used for venous thromboembolism chemoprophylaxis following injury. However, unfractionated heparin (UFH) is a less expensive option. We compared LMWH and UFH for prevention of posttraumatic deep venous thrombosis (DVT) and pulmonary embolism (PE). METHODS Trauma patients 15 years or older with at least one administration of venous thromboembolism chemoprophylaxis at two level I trauma centers with similar DVT-screening protocols were identified. Center 1 administered UFH every 8 hours for chemoprophylaxis, and center 2 used twice-daily antifactor Xa-adjusted LMWH. Clinical characteristics and primary chemoprophylaxis agent were evaluated in a two-level logistic regression model. Primary outcome was incidence of DVT and PE. RESULTS There were 3,654 patients: 1,155 at center 1 and 2,499 at center 2. The unadjusted DVT rate at center 1 was lower than at center 2 (3.5% vs. 5.0%; p = 0.04); PE rates did not significantly differ (0.4% vs. 0.6%; p = 0.64). Patients at center 2 were older (mean, 50.3 vs. 47.3 years; p < 0.001) and had higher Injury Severity Scores (median, 10 vs. 9; p < 0.001), longer stays in the hospital (mean, 9.4 vs. 7.0 days; p < 0.001) and intensive care unit (mean, 3.0 vs. 1.3 days; p < 0.001), and a higher mortality rate (1.6% vs. 0.6%, p = 0.02) than patients at center 1. Center 1's patients received their first dose of chemoprophylaxis earlier than patients at center 2 (median, 1.0 vs. 1.7 days; p < 0.001). After risk adjustment and accounting for center effects, primary chemoprophylaxis agent was not associated with risk of DVT (odds ratio, 1.01; 95% confidence interval, 0.69-1.48; p = 0.949). Cost calculations showed that UFH was less expensive than LMWH. CONCLUSION Primary utilization of UFH is not inferior to LMWH for posttraumatic DVT chemoprophylaxis and rates of PE are similar. Given that UFH is lower in cost, the choice of this chemoprophylaxis agent may have major economic implications. LEVEL OF EVIDENCE Prognostic and epidemiological, level II; Therapeutic, level III.

Isolated Intracranial Hemorrhage in Elderly Patients With Pre-Injury Anticoagulation: Is Full Trauma Team Activation Necessary? J Surg Res 2021; 268:491-497. [PMID: 34438190 DOI: 10.1016/j.jss.2021.07.021] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2021] [Revised: 07/16/2021] [Accepted: 07/22/2021] [Indexed: 12/28/2022]
Abstract
BACKGROUND Traumatic intracranial hemorrhage (ICH) is a highly morbid injury, particularly among elderly patients on preinjury anticoagulants (AC). Many trauma centers initiate full trauma team activation (FTTA) for these high-risk patients. We sought to determine if FTTA was superior compared with those who were evaluated as a trauma consultation (CON). METHODS Patients aged ≥55 on preinjury AC who presented from January 2015 to December 2019 with blunt isolated head injury (non-head AIS ≤2) and confirmed ICH were identified. CON patients and FTTA patients were matched by age and head AIS. Cox proportional hazard model was used to assess patient and injury characteristics with mortality and survivor discharge disposition. REASULTS There were 45 CON patients and 45 FTTA patients. Mean age was 80 years in both groups. Fall was the most common mechanism (98% CON vs. 92% FTTA). Glasgow Coma Score (GCS) was lower in FTTA (14 vs. 15, p<0.01). CON had a significantly longer time from arrival to CT scan (1.3 vs. 0.4 hrs, p<0.01). Hospital days were similar (CON: 3.9 vs. FTTA: 3.7 days). However, CON had increased ventilator use (p=0.03). Lower admission GCS was the only factor associated with increased risk of death. Among survivors, only head AIS increased the risk of discharge to a level of care higher than that of preinjury (p=0.01). CONCLUSION There was no difference in mortality or adverse discharge disposition between FTTA and CON, although FTTA was associated with a more rapid evaluation and diagnosis. Any alteration in GCS was strongly associated with mortality and should prompt evaluation by FTTA.

Abstract
BACKGROUND Partial resuscitative endovascular balloon occlusion of the aorta (pREBOA) is a technology that occludes aortic flow and allows for controlled deflation and restoration of varying distal perfusion. Carotid flow rates (CFRs) during partial deflation are unknown. Our aim was to measure CFR with the different pREBOA balloon volumes and correlate those to the proximal mean arterial pressure (PMAP) and a handheld pressure monitoring device (COMPASS; Mirador Biomedical, Seattle, WA). METHODS Ten swine underwent a hemorrhagic injury model with carotid and iliac arterial pressures monitored via arterial lines. Carotid and aortic flow rates were monitored with Doppler flow probes. A COMPASS was placed to monitor proximal pressure. The pREBOA was inflated for 15 minutes then partially deflated for an aortic flow rate of 0.7 L/min for 45 minutes. It was then completely deflated. Proximal mean arterial pressures and CFR were measured, and correlation was evaluated. Correlation between CRF and COMPASS measurements was evaluated. RESULTS Carotid flow rate increased 240% with full inflation. Carotid flow rate was maintained at 100% to 150% of baseline across a wide range of partial deflation. After full deflation, CFR transiently decreased to 45% to 95% of baseline. There was strong positive correlation (r > 0.85) between CFR and PMAP after full inflation, and positive correlation with partial inflation (r > 0.7). Carotid flow rate had strong correlation with the COMPASS with full REBOA (r > 0.85) and positive correlation with pREBOA (r > 0.65). CONCLUSION Carotid flow rate is increased in a hemorrhagic model during full and partial inflation of the pREBOA and correlates well with PMAP. Carotid perfusion appears maintained across a wide range of pREBOA deflation and could be readily monitored with a handheld portable COMPASS device instead of a standard arterial line setup.

Identifying risk factors for enteral access procedures in neonates with congenital diaphragmatic hernia: A novel risk-assessment score. J Pediatr Surg 2021; 56:1130-1134. [PMID: 33745741 DOI: 10.1016/j.jpedsurg.2021.02.029] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Accepted: 02/05/2021] [Indexed: 10/22/2022]
Abstract
BACKGROUND/PURPOSE The purpose of this study was to evaluate the characteristics of neonates with congenital diaphragmatic hernia (CDH) undergoing enteral access procedures (gastrostomy or jejunostomy) during their initial hospitalization, and establish a clinical scoring system based on these characteristics. METHODS Data were obtained from the multicenter, multinational CDH Study Group database (CDHSG Registry) between 2007 and 2019. Patients were randomly partitioned into model-derivation and validation subsets. Weighted scores were assigned to risk factors based on their calculated β-coefficients after logistic regression. RESULTS Of 4537 total patients, 597 (13%) underwent gastrostomy or jejunostomy tube placement. In the derivation subset, factors independently associated with an increased risk for enteral access included oxygen requirement at 30-days, chromosomal abnormalities, gastroesophageal reflux, major cardiac anomalies, ECMO requirement, liver herniation, and increased defect size. Based on the devised scoring system, patients could be stratified into very low (0-4 points; <10% risk), low (5-6 points; 10-20% risk), intermediate (7-9 points; 30-60% risk), and high risk (≥10 points; 70% risk) groups for enteral access. CONCLUSION This study identifies risk factors associated with enteral access procedures in neonates with congenital diaphragmatic hernia and establishes a novel scoring system that may be used to guide clinical decision making in those with poor oral feeding. TYPE OF STUDY Prognosis study.

Abstract
BACKGROUND Partial resuscitative endovascular balloon occlusion of the aorta (pREBOA) attempts to minimize ischemia/reperfusion injury while controlling hemorrhage. There are little data on optimal methods to evaluate and titrate partial flow, which typically requires invasive arterial line monitoring. We sought to examine the use of a miniaturized handheld digital pressure device (COMPASS; Mirador Biomedical, Seattle, WA) for pREBOA placement and titration of flow. METHODS Ten swine underwent standardized hemorrhagic shock. Carotid and iliac pressures were monitored with both arterial line and COMPASS devices, and flow was monitored by aortic and superior mesenteric artery flow probes. Partial resuscitative endovascular balloon occlusion of the aorta was inflated to control hemorrhage for 15 minutes before being deflated to try targeting aortic flow of 0.7 L/min (using only the COMPASS device) by an operator blinded to the arterial line pressures and aortic flow. Correlations between COMPASS and proximal/distal arterial line were evaluated, as well as actual aortic flow. RESULTS There was strong correlation between the distal mean arterial pressure (MAP) and the distal COMPASS MAP (r = 0.979, p < 0.01), as well as between the proximal arterial line and the proximal COMPASS on the pREBOA (r = 0.989, p < 0.01). There was a significant but weaker correlation between the distal compass MAP reading and aortic flow (r = 0.47, p < 0.0001), although it was not clinically significant and predicted flow was not achieved in a majority of the procedures. Of 10 pigs, survival times ranged from 10 to 120 minutes, with a mean survival of 50 minutes, and 1 pig surviving to 120 minutes. CONCLUSION Highly reliable pressure monitoring is achieved proximally and distally without arterial lines using the COMPASS device on the pREBOA. Despite accurate readings, distal MAPs were a poor indicator of aortic flow, and titration based upon distal MAPs did not provide reliable results. Further investigation will be required to find a suitable proxy for targeting specific aortic flow levels using pREBOA.

Abstract
BACKGROUND We compared surgical device malfunction reports in the Food and Drug Administration (FDA) public Manufacturer and User Facility Device Experience (MAUDE) with those in the FDA nonpublic Alternative Summary Reporting (ASR). METHODS General surgery device product code categories in MAUDE and ASR from 1999 to 2018 were identified. Changes in the rates of categories and adverse events were evaluated by Poisson regression. RESULTS There were 283,308 (72%) general surgical device malfunctions in MAUDE and 109,954 (28%) in ASR. Reports increased annually in ASR versus MAUDE, particularly for surgical staplers and clip devices (p < 0.05). ASR contained approximately 80% of these reports; MAUDE 20%. In MAUDE, 42.9% of surgical device malfunctions and 20.2% of stapler/clip malfunctions resulted in patient injury or death. ASR listed no injury or death information. CONCLUSIONS ASR contained a significant portion of surgical device malfunctions hidden from public scrutiny. Access to such data is essential to safe surgical care.

Abstract
BACKGROUND Methamphetamine (METH) is associated with an elevated risk of injury and the outcomes in the elderly remain unclear. We analyzed METH's impact in elderly trauma patients. METHODS Retrospective analysis (2009-2018) of trauma patients at a Level I trauma center. Elderly patients were defined as age ≥55. Substance use was identified by blood alcohol test and urine drug screen. Cox proportional hazard model was used to assess patient and injury characteristics with mortality. RESULTS Of 15,770 patient encounters with substance use testing, 5278 (34%) were elderly. Elderly METH use quadrupled over time (2%-8%; p < 0.01). Elderly METH + patients were more likely to require surgical intervention (35% vs. 17%), mechanical ventilation (15% vs. 7%), and a longer hospitalization (6.5 vs. 3.6 days) compared with elderly substance negative. Multivariate analysis showed increasing age, ventilator use, and injury severity were associated with mortality (ps < 0.01); METH was not related to mortality. CONCLUSION Substance use in elderly trauma patients increased significantly. METH use in elderly trauma patients is a risk factor for significantly greater resource utilization.

Abstract
BACKGROUND Outcomes following damage control laparotomy for trauma have been studied in detail. However, outcomes following a single operation, or "single-look trauma laparotomy" (SLTL), have not. We evaluated the association between SLTL and both short-term and long-term outcomes in a large population-based data set. METHODS The California Office of Statewide Health Planning and Development patient discharge database was evaluated for calendar years 2007 through 2014. Injured patients with SLTL during their index admission were identified using International Classification of Diseases, Ninth Revision, Clinical Modification procedure codes. Diagnosis and procedure codes were used to identify specific abdominal organ injuries, surgical interventions, and perioperative complications. Subsequent acute care admissions were examined for postoperative complications and related surgical interventions. Clinical characteristics, injuries, surgical interventions, and outcomes were analyzed by mechanism of injury. RESULTS There were 2113 patients with SLTL during their index admission; 712 (33.7%) had at least one readmission to an acute care facility. Median time to first readmission was 110 days. Penetrating mechanism was more common than blunt (60.6% vs. 39.4%). Compared to patients with penetrating injury, blunt-injured patients had a significantly higher median Injury Severity Score (9 vs. 18, p < 0.0001) and a significantly higher mortality rate during the index admission (4.1% vs. 27.0%, p < 0.0001). More than 30% of SLTL patients requiring readmission had a surgery-related complication. The most common primary reasons for readmission were bowel obstruction (17.7%), incisional hernia (11.8%), and infection (9.1%). There was no significant association between mechanism of injury and development of surgery-related complications requiring readmission. CONCLUSIONS Patients with SLTL had postinjury morbidity and mortality, and more than 30% required readmission. Complication rates for SLTL were comparable to those reported for emergency general surgery procedures. Patients should be educated on signs and symptoms of the most common complications before discharge following SLTL. Further investigation should focus on the factors associated with the development of these complications. LEVEL OF EVIDENCE Prognostic and epidemiologic study, level III.

Abstract
OBJECTIVE Open repair of ruptured abdominal aortic aneurysm (rAAA) has shown improved outcomes at trauma centers. Whether the benefit of trauma center designation extends to endovascular repair of rAAA is unknown. METHODS Retrospective cohort study using the California Office of Statewide Health Planning and Development 2007 to 2014 discharge database to identify patients with rAAA. Data included demographic and admission factors, discharge disposition, International Classification of Diseases, Ninth Revision, Clinical Modification codes, and hospital characteristics. Hospitals were categorized by trauma center designation and teaching hospital status. The effect of repair type and trauma center designation (level I, level II, or other-other trauma centers and nondesignated hospitals) was evaluated to determine rates and risks of 9 postoperative complications, in-hospital mortality, and 30-day postdischarge mortality. RESULTS Of 1941 rAAA repair patients, 61.2% had open and 37.8% had endovascular; 1.0% had both. Endovascular repair increased over the study interval. Hospitals were 12.0% level I, 25.0% level II, and 63.0% other. A total of 48.7% of hospitals were teaching hospitals (level I, 100%; level II, 42.2%; and other, 41.8%). Endovascular repair was significantly more common at teaching hospitals (41.5% vs 34.3%, P < .001) and was the primary repair method at level I trauma centers (P < .001). Compared with open repair, endovascular repair was protective for most complications and in-hospital mortality. The risk for in-hospital mortality was highest among endovascular patients at level II trauma centers (hazard ratio 1.67, 95% confidence interval [CI]: 0.95-2.92) and other hospitals (hazard ratio 1.66, 95% CI: 1.01-2.72). CONCLUSIONS Endovascular repair overall was associated with a lower risk of adverse outcomes. Endovascular repair at level I trauma centers had a lower risk of in-hospital mortality which may be a result of their teaching hospital status, organizational structure, and other factors. The weight of the contributions of such factors warrants further study.

Abstract
BACKGROUND The purpose of this study was to evaluate the epidemiology and management of pediatric vascular extremity trauma to assess injury patterns and other factors that may contribute to poor outcomes. METHODS Using the California Office of Statewide Health Planning and Development discharge database, we identified pediatric patients with extremity arterial trauma admitted to acute-care hospitals from 2007 to 2014. Demographics, management patterns, and outcomes were collected and analyzed. RESULTS A total of 775 patients were treated for an extremity arterial injury. Overall, 40% were admitted to pediatric trauma centers and 39% to adult trauma centers. Management was predominantly by open surgical repair. Injury to the common femoral artery was associated with mortality (Hazard Ratio 3.9; 95% CI 1.1-14.5; p < 0.05). Popliteal artery injuries (Odds Ratio [OR] 4.8; 95% CI 1.2-19.9; p < 0.05) and anterior tibial artery injuries (OR 7.1; 95% CI 1.4-37.3; p < 0.05) had an increased risk of amputation. There was no difference in amputation or mortality rates by hospital category. CONCLUSIONS Pediatric extremity arterial injuries are rare. In California, outcomes are similar by hospital type. Common femoral artery injuries are associated with an increased risk of mortality, while popliteal and anterior tibial artery injuries are associated with an increased risk of amputation.

Abstract
BACKGROUND Complicated gallstone disease (CGD) is a common condition requiring intervention during pregnancy to avert adverse birth outcomes (ABO). METHODS Cohort study using the California OSHPD 2007-2014 database. Records of pregnant patients were analyzed for gallbladder calculus within four months of delivery. Biliary system interventions were evaluated as the primary exposure. RESULTS Of 7,597 patients, those with CGD had a greater likelihood of biliary system procedures than those with uncomplicated gallstone disease (36.6% vs. 2.5%, p < 0.001). Patients with CGD also had increased odds of ABO (OR 2.02, 95% CI, 1.48-2.76). Compared to patients without biliary system procedures, those with interventions for gallstones had an OR of 3.46 (95% CI, 2.48-4.82) for ABO. After adjustment, biliary system intervention for CGD had an even greater risk of ABO (OR 4.26, 95% CI, 2.86-6.35). CONCLUSIONS The risk of ABO is significantly increased in women with CGD and intervention for gallstones.

Abstract
BACKGROUND Although adhesive small-bowel obstruction (ASBO) is frequently managed nonoperatively, little is known regarding outcomes on readmission following this approach. Using a large population-based dataset, we evaluated risk factors for operative intervention and mortality at readmission in patients with ASBO who were initially managed nonoperatively. METHODS The ASBO patients were identified in the California Office of Statewide Health Planning and Development 2007 to 2014 patient discharge database. Patients who were managed operatively at index admission or had an International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code for nonadhesive obstructive small bowel disease were excluded. Associations between risk factors and both operative intervention and death following readmission were evaluated using survival analysis. RESULTS Among 15,963 ASBO patients, 3,103 (19.4%) had at least one readmission. The 1,069 (34.5%) who received an operation during their first readmission presented sooner (175 days vs. 316 days, p < 0.001) and were more likely to die during that readmission (5.2% vs. 0.7%, p < 0.001). Operative management at first readmission was associated with younger age, fewer comorbidities, and shorter times to readmission. Patients operatively managed at first readmission had longer times to second readmission compared with nonoperative patients. Stratified analyses using nonoperative patients as the reference over the study period revealed that patients who underwent lysis of adhesions and bowel resection were 5.04 times (95% confidence interval [CI], 2.82-9.00) as likely to die while those who underwent lysis only were 2.09 times (95% CI, 1.14-3.85) as likely to die. Patients with bowel resection only were at an increased risk for subsequent interventions beyond the first readmission (hazard ratio, 1.79; 95% CI, 1.11-2.87). CONCLUSION In a large cohort readmitted for ASBO and initially managed nonoperatively, subsequent operative intervention conferred a greater risk of death and a longer time to readmission among survivors. Prospective research is needed to further delineate outcomes associated with initial nonoperative management of ASBO. LEVEL OF EVIDENCE Prognostic and epidemiological, level III.

Abstract
INTRODUCTION Pre-existing medical conditions (PEC) represent a unique domain of risk among older trauma patients. The study objective was to develop a metric to quantify PEC burden for trauma patients. METHODS A cohort of 4526 non-severe blunt-injured trauma patients aged 55 years and older admitted to a Level I trauma center between January 2006 and December 2012 were divided into development (80%) and test (20%) sets. Cox regression was used to develop the model based on in-hospital and 90-day mortality. Regression coefficients were converted into a point-based PEC Risk Score. Performance of the PEC Risk Score was compared in the test set with two other PEC-based metrics and three injury-based metrics. An external cohort of 2284 trauma patients admitted in 2013 was used to evaluate combined metric performance. RESULTS Total mortality was 9.4% and 9.1% in the development and test set, respectively. The final model included 12 PEC. In the test set, the PEC Risk Score (c-statistic: 79.7) was superior for predicting in-hospital and 90-day mortality compared with all other metrics. For in-hospital mortality alone, the PEC Risk Score similarly outperformed all other metrics. Combination of the PEC Risk Score and any injury-based metric significantly improved prediction compared with any injury-based metric alone. CONCLUSION Our 12-item PEC Risk Score performed well compared with other metrics, suggesting that the classification of trauma-related mortality risk may be improved through its use. Among non-severely injured older trauma patients, the utility of prognostic metrics may be enhanced through the incorporation of comorbidities.

Abstract
BACKGROUND Research comparing enoxaparin with unfractionated heparin (UFH) given every 12 hours for venous thromboembolism (VTE) prophylaxis after trauma overlooks original recommendations that UFH be given every 8 hours. We conducted a prospective, randomized, noninferiority trial comparing UFH every 8 hours and standard enoxaparin every 12 hours. We hypothesized that the incidence of VTE in trauma patients receiving UFH every 8 hours would be no more than 10% higher than that in patients receiving enoxaparin every 12 hours. METHODS Trauma patients who met criteria for VTE prophylaxis at a Level I trauma center were randomly assigned to 5,000-U UFH every 8 hours or 30-mg enoxaparin every 12 hours between November 2012 and September 2014. Surveillance duplex ultrasound was performed twice weekly on intensive care unit patients and weekly on ward patients. Primary end points were deep vein thrombosis diagnosed by duplex ultrasound and pulmonary embolism diagnosed by computed tomography angiography. RESULTS Of 495 randomized patients, 220 received UFH and 216 received enoxaparin for analysis. Overall, 105 in the UFH group and 103 in the enoxaparin group underwent VTE surveillance or diagnostic testing. In the analysis of randomized patients who received treatment, UFH was noninferior compared with enoxaparin (absolute VTE risk difference, 3.1%; 95% confidence interval, -1.6% to 7.7%; p = 0.196); however, in the screening ultrasound group, the noninferiority of UFH was inconclusive (absolute VTE risk difference, 6.5%; 95% confidence interval, -2.9% to 15.8%; p = 0.179). The two treatments did not differ with regard to adverse events. The pharmaceutical cost for the regimen of UFH ($2,809) was nearly 20-fold lower than that for enoxaparin ($54,138). CONCLUSION A regimen of UFH every 8 hours may be noninferior to enoxaparin every 12 hours for the prevention of VTE following trauma. Given UFH's cost advantage, the use of UFH for VTE prophylaxis may offer greater value. LEVEL OF EVIDENCE Therapeutic/care management study, level II.

Abstract
BACKGROUND Optimal care of trauma patients requires cost-effective organization and commitment of trauma center resources. We examined the impact of creating a dedicated trauma care unit (TCU) and adding advanced practice nurses on the quality and cost of care at an adult Level I trauma center. METHODS Patient demographic and injury data, length of stay, complications, outcomes, and total direct cost of care were evaluated for four 1-year intervals in the recent history of our trauma center: Year A, a trauma team of in-house trauma surgeons and resident physicians; Year B, the addition of nurse practitioners to the trauma team 5 days/week; Year C, the creation of a dedicated TCU for all non intensive care unit trauma patients; and Year D, the addition of a permanent clinical nurse specialist and an increase in nurse practitioner coverage to 7 days/week. For each year, value was determined by calculating the median cost of a survivor and the median cost of a survivor with no complications. Significance was attributed to p<0.05. RESULTS Patient volume increased from 1,927 in year A to 2,546 by year D. Over the period of study, there was an increase in blunt trauma (87.1-89.9%; p<0.05), median Injury Severity Score (5-6; p<0.05), and patients aged ≥65 years (11.4-19.8%; p<0.05). However, risk-adjusted mortality was unchanged. There was a decrease in patients with a complication (20.8-14.9%; p < 0.05), median intensive care unit length of stay (39.5-23.4 hours; p < 0.05), and median cost of care ($4,306-$3,698; p<0.05). Value increased: both the median costs of a survivor and of a survivor with no complications decreased from $4,259 to $3,658 (p<0.05) and from $3,898 to $3,317 (p<0.05), respectively. The median cost of a survivor with severe injury (Injury Severity Score ≥15) decreased from $17,651 to $12,285 (p<0.05). CONCLUSION The addition of a dedicated TCU and advanced practice nurses improved the quality and reduced the cost of care, resulting in increased value at an adult Level I trauma center.

Abstract
Aldose reductase (AR) is implicated to play a critical role in diabetes and cardiovascular complications because of the reaction it catalyzes. Our data reveal that peroxisome proliferator WY 14,643, follows a pure non-competitive inhibition pattern in the aldehyde reduction activity as well as in the alcohol oxidation activity of AR. This finding communicates for the first time a novel feature of WY 14,643 in regulating AR activity. In addition, this observation indicates that AR, AR-like proteins and aldo-keto reductase (AKR) members may be involved in the WY 14,643 mechanism of action when it is administered as PPAR agonist.
