RESUMEN
INTRODUCTION: A 2003 landmark study identified the prevalence of eTIC at 28% with a strong association with mortality of 8.9%. Over the last 20 years there have been significant advances in both the fundamental understanding of eTIC and therapeutic interventions. METHODS: A retrospective cohort study was performed from 2018-2022 on patients ≥18 using prospectively collected data from two level 1 trauma centers and compared to data from 2003. Demographics, laboratory data and clinical outcomes were obtained. RESULTS: There were 20,107 patients meeting criteria: 65% male, 85% blunt, mean age 54 ± 21 years, median injury severity score (ISS) 10 [10, 18]), 8% of patients were hypotensive on arrival, with an all-cause mortality 6.0%. The prevalence of eTIC remained high at 32% in patients with an abnormal PT and 10% with an abnormal PTT, for an overall combined prevalence of 33.4%. Coagulopathy had a major impact on mortality over all injury severity ranges, with the greatest impact with lower ISS. In a hybrid logistic regression/Classification and Regression Trees analysis, coagulopathy was independently associated with a 2.1-fold increased risk of mortality (95% CI 1.5-2.9); the predictive quality of the model was excellent (AUROC 0.932). CONCLUSION: The presence of eTIC conferred a higher risk of death across all disease severities and was independently associated with a greater risk of death. Biomarkers of coagulopathy associated with eTIC remain strongly predictive of poor outcome despite advances in trauma care.
RESUMEN
INTRODUCTION: This study aimed to assess perioperative bleeding complications and in-hospital mortality in patients requiring emergency general surgery presenting with a history of antiplatelet (AP) versus direct oral anticoagulant (DOAC) versus warfarin use. METHODS: A prospective observational study across 21 centers between 2019 and 2022 was conducted. Inclusion criteria were age 18 years or older, and DOAC, warfarin, or AP use within 24 hours of an emergency general surgery procedure. Outcomes included perioperative bleeding and in-hospital mortality. The study was conducted using analysis of variance, χ 2 , and multivariable regression models. RESULTS: Of the 413 patients, 221 (53.5%) reported AP use, 152 (36.8%) DOAC use, and 40 (9.7%) warfarin use. The most common indications for surgery were obstruction (23% [AP], 45% [DOAC], and 28% [warfarin]), intestinal ischemia (13%, 17%, and 23%), and diverticulitis/peptic ulcers (7%, 7%, and 15%). Compared with DOAC use, warfarin use was associated with significantly higher perioperative bleeding complication (odds ratio [OR], 4.4 [95% confidence interval (CI), 2.0-9.9]). There was no significant difference in perioperative bleeding complication between DOAC and AP use (OR, 0.7 [95% CI, 0.4-1.1]). Compared with DOAC use, there was no significant difference in mortality between warfarin use (OR, 0.7 [95% CI, 0.2-2.5]) or AP use (OR, 0.5 [95% CI, 0.2-1.2]). After adjusting for confounders, warfarin use (OR, 6.3 [95% CI, 2.8-13.9]), medical history, and operative indication were associated with an increase in perioperative bleeding complications. However, warfarin was not independently associated with risk of mortality (OR, 1.3 [95% CI, 0.39-4.7]), whereas intraoperative vasopressor use (OR, 4.7 [95% CI, 1.7-12.8]), medical history, and postoperative bleeding (OR, 5.5 [95% CI, 2.4-12.8]) were. CONCLUSION: Despite ongoing concerns about the increase in DOAC use and lack of readily available reversal agents, this study suggests that warfarin, rather than DOACs, is associated with higher perioperative bleeding complications. However, that risk does not result in an increase in mortality, suggesting that perioperative decisions should be dictated by patient disease and comorbidities rather than type of AP or anticoagulant use. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

Maternal autonomy is associated with improved healthcare utilization/outcomes for mothers and babies in low- and middle-income countries. We investigated the trends in the prevalence and factors associated with maternal autonomy in Bangladesh. This cross-sectional study analyzed the Bangladesh Demographic and Health Survey for 1999-00, 2004, 2007, 2011, 2014, and 2017-18. Maternal autonomy was defined as at least one decision-making ability regarding healthcare, large household purchases, and freedom of mobility. We included 15-49-year-old mothers with at least one live-birth in the past three years. We compared the samples based on the presence of autonomy and reported the trends in prevalence (95% confidence intervals (CIs)) across the survey years. Lastly, we performed multilevel logistic regression to report prevalence odds ratios (PORs) for the associated factors. Variables investigated as potential factors included maternal age, number of children, maternal education, paternal education, current work, religion, mass media exposure, wealth quintile, place and division of residence, and survey years. The prevalence of 'any' maternal autonomy was 72.0% (95% CI: 70.5-73.5) in 1999-00 and increased to 83.8% (95% CI: 82.7-84.9) in 2017-18. In adjusted analysis, mothers with older age, higher education, work outside the home, and mass media exposure had higher odds of autonomy than their counterparts (POR > 1, p < 0.05). For instance, compared to mothers without any formal education, the odds of autonomy were significantly (p < 0.001) higher among mothers with primary (adjusted POR: 1.2, 95% CI: 1.1-1.4), secondary (adjusted POR: 1.4, 95% CI: 1.2-1.6), and college/above (adjusted POR: 1.9, 95% CI: 1.6-2.2) education. While the level of maternal autonomy has increased, a substantial proportion still do not have autonomy. Expanding educational and earning opportunities may increase maternal autonomy. Further research should investigate other ways to improve it as well.
RESUMEN
BACKGROUND: Bleeding after cardiac surgery is common and continues to require 10-20% of the national blood supply. Transfusion of allogeneic blood is associated with increased morbidity and mortality. Excessive protamine in the absence of circulating heparin after weaning off CPB can cause anticoagulation and precipitate bleeding. Hence, adequate dose calculation of protamine is crucial yet under evaluated. STUDY DESIGN: Retrospective cohort study. METHODS: We conducted a retrospective bi-institutional analysis of cardiac surgical patients who underwent cardiopulmonary bypass (CPB)-assisted cardiac surgery to assess the impact of protamine dosing in transfusion practice. Total 762 patients were identified from two institutions using electronic medical records and the Society of Thoracic Surgery (STS) database who underwent cardiac surgery using CPB. Patients were similar in demographics and other baseline characteristics. We divided patients into two groups based on mg of protamine administered to neutralize each 100 U of unfractionated heparin (UFH)-low-ratio group (Protamine: UFH ≤ 0.8) and high-ratio group (Protamine: UFH > 0.8). RESULTS: We observed a higher rate of blood transfusion required in high-ratio group (ratio >0.8) compared with low-ratio group (ratio ≤0.8) (p < .001). The increased requirement was consistently demonstrated for intraoperative transfusions of red blood cells, plasma, platelets, and cryoprecipitate. CONCLUSION: High protamine to heparin ratio may cause increased bleeding and transfusion in cardiac surgical patients. Protamine to heparin ratio of 0.8 or lower is sufficient to neutralize circulating heparin after weaning off cardiopulmonary bypass.

BACKGROUND: Although there are discrepancies in the development and progression of IBD based on biologic sex, little is known about differences in postoperative outcomes between men and women undergoing surgery for this condition. OBJECTIVE: To compare rates of anastomotic leaks, wound complications, and serious adverse events between men and women undergoing surgery for IBD. DESIGN: This was a retrospective cohort study. SETTINGS: Data were obtained from the American College of Surgeons National Surgical Quality Improvement Program IBD Collaborative database, which includes 15 high-volume IBD surgery centers. PATIENTS: All adult patients undergoing surgery for IBD were included. Participants with missing data for exposure or outcome variables were excluded. MAIN OUTCOME MEASURES: Rates of anastomotic leaks, wound complications, and serious adverse events were compared between women and men. RESULTS: A total of 3143 patients were included. There was a significant association between sex and BMI, IBD type, and preoperative medication use. Women had decreased odds of serious adverse events compared to men (OR 0.73; 95% CI, 0.55-0.96), but there was no significant association between sex and anastomotic leaks or wound complications. IBD type was found to be an effect measure modifier of the relationship between sex and serious adverse events. Among patients with ulcerative colitis, women had a 54% decrease in the odds of serious adverse events compared to men, whereas there was no significant difference between women and men with Crohn's disease. LIMITATIONS: This study was limited by capturing only 30 days of postoperative outcomes. CONCLUSIONS: Women undergoing surgery for ulcerative colitis had decreased odds of serious adverse events compared to men. Understanding sex-based differences in outcomes allows clinicians to make patient-centered decisions regarding surgical planning and perioperative management for patients with IBD.

DIFERENCIAS BASADAS EN EL SEXO EN LOS RESULTADOS QUIRRGICOS DE LA ENFERMEDAD INFLAMATORIA INTESTINAL: ANTECEDENTES:Aunque existen discrepancias en el desarrollo y la progresión de la enfermedad inflamatoria intestinal según el sexo biológico, se sabe poco sobre las diferencias en los resultados postoperatorios entre hombres y mujeres sometidos a cirugía por esta afección.OBJETIVO:Nuestro objetivo fue comparar las tasas de fugas anastomóticas, complicaciones de las heridas y eventos adversos graves entre hombres y mujeres sometidos a cirugía por enfermedad inflamatoria intestinal.DISEÑO:Este fue un estudio de cohorte retrospectivo.AJUSTES:Los datos se obtuvieron de la base de datos del Programa Nacional de Mejora de la Calidad Quirúrgica del Colegio Americano de Cirujanos para la Enfermedad Inflamatoria Intestinal, que incluye 15 centros de cirugía de enfermedad inflamatoria intestinal de alto volumen.PACIENTES:Se incluyeron todos los pacientes adultos sometidos a cirugía por enfermedad inflamatoria intestinal. Se excluyeron los sujetos a los que les faltaban datos sobre exposición o variables de resultado.PRINCIPALES MEDIDAS DE RESULTADO:Se compararon las tasas de fugas anastomóticas, complicaciones de las heridas y eventos adversos graves entre mujeres y hombres.RESULTADOS:Se incluyeron un total de 3.143 pacientes. Hubo una asociación significativa entre el sexo y el índice de masa corporal, el tipo de enfermedad inflamatoria intestinal y el uso de medicación preoperatoria. Las mujeres tuvieron menores probabilidades de sufrir eventos adversos graves en comparación con los hombres (OR = 0,73; IC del 95 %: 0,55 a 0,96), pero no hubo una relacion significativa entre el sexo y las fugas anastomóticas o las complicaciones de las heridas. Se encontró que el tipo de enfermedad inflamatoria intestinal era un modificador de la medida del efecto de la relación entre el sexo y los eventos adversos graves. Entre los pacientes con colitis ulcerosa, las mujeres tuvieron una disminución del 54 % en las probabilidades de sufrir eventos adversos graves en comparación con los hombres, mientras que no hubo diferencias significativas entre mujeres y hombres con enfermedad de Crohn.LIMITACIONES:Este estudio estuvo limitado al capturar solo 30 días de resultados posoperatorios.CONCLUSIONES:Las mujeres sometidas a cirugía por colitis ulcerosa tuvieron menores probabilidades de sufrir eventos adversos graves en comparación con los hombres. Comprender las diferencias en los resultados basadas en el sexo permite a los médicos tomar decisiones centradas en el paciente con respecto a la planificación quirúrgica y el manejo perioperatorio de los pacientes con enfermedad inflamatoria intestinal.

BACKGROUND: Appropriate and timely care is essential in the management of severe acute pancreatitis (SAP). We hypothesized that transferred patients with SAP undergoing procedural intervention would have higher mortality compared to those managed directly at academic centers. METHODS: This was a retrospective analysis of Maryland's statewide claims database from 2009 to 2022 of adult patients admitted with a primary diagnosis of SAP (acute pancreatitis with organ failure). Patients were divided into three groups: those admitted directly from the emergency room to academic facilities (AD), non-academic facilities (NA), or transferred to academic facilities (TR). Procedural intervention included endoscopic, percutaneous image-guided, or surgical. The primary outcome was in-hospital mortality. Secondary outcomes were admission costs, length of stay (LOS), and intensive care unit (ICU) admission. RESULTS: There were 7,648 (48.9%) in the NA group, 6,682 (42.7%) in the AD group and 1,316 (8.4%) in the TR group. On regression analysis, odds of death were 0.57x lower in the NA group and 0.67x lower in the AD group compared to transfers (<0.001). Procedural intervention was not associated with increased mortality. Transferred patients had longer median LOS (11 vs NA = 5, AD = 6, p < 0.001), increased median cost of admission ($41k vs NA = $12k, AD = $17k, p < 0.001) and greater ICU admission (45.6% vs NA = 20.6%, AD = 23.9%, p < 0.001). CONCLUSION: Transferred patients have greater burden of illness and cost of care without evidence of improved outcomes in the management of SAP regardless of procedural intervention. Transfer criteria for patients with SAP must be further refined to reduce unnecessary transfers.

BACKGROUND: While direct oral anticoagulant (DOAC) use is increasing in the Emergency General Surgery (EGS) patient population, our understanding of their bleeding risk in the acute setting remains limited. Therefore, the objective of this study was to determine the prevalence of perioperative bleeding complications in patients using DOACs versus warfarin and AP therapy requiring urgent/emergent EGS procedures (EGSPs). METHODS: This was a prospective observational trial, conducted between 2019 and 2022, across 21 centers. Inclusion criteria were 18 years or older, DOAC, warfarin/AP use within 24 hours of requiring an urgent/emergent EGSP. Demographics, preoperative, intraoperative, and postoperative data were collected. ANOVA, χ 2 , and multivariable regression models were used to conduct the analysis. RESULTS: Of the 413 patients enrolled in the study, 261 (63%) reported warfarin/AP use and 152 (37%) reported DOAC use. Appendicitis and cholecystitis were the most frequent indication for operative intervention in the warfarin/AP group (43.4% vs. 25%, p = 0.001). Small bowel obstruction/abdominal wall hernias were the main indication for operative intervention in the DOAC group (44.7% vs. 23.8%, p = 0.001). Intraoperative, postoperative, and perioperative bleeding complications and in-hospital mortality were similar between the two groups. After adjusting for confounders, a history of chemotherapy (odds ratio [OR], 4.3; p = 0.015) and indication for operative intervention including occlusive mesenteric ischemia (OR, 4.27; p = 0.016), nonocclusive mesenteric ischemia (OR, 3.13; p = 0.001), and diverticulitis (OR, 3.72; p = 0.019) were associated with increased perioperative bleeding complications. The need for an intraoperative transfusion (OR, 4.87; p < 0.001), and intraoperative vasopressors (OR, 4.35; p = 0.003) were associated with increased in-hospital mortality. CONCLUSION: Perioperative bleeding complications and mortality are impacted by the indication for EGSPs and patient's severity of illness rather than a history of DOAC or warfarin/AP use. Therefore, perioperative management should be guided by patient physiology and indication for surgery rather than the concern for recent antiplatelet or anticoagulant use. LEVEL OF EVIDENCE: Prognostic and Epidemiologic; Level III.

BACKGROUND: Recent studies in severely injured patients suggest an important role of von Willebrand Factor (VWF) and ADAMTS13 in the endotheliopathy of trauma (EoT). We hypothesized that the early use of cryoprecipitate would be effective as an endothelial protector by supplementing physiologic VWF and ADAMTS13 to reverse the EoT. We tested a pathogen-reduced lyophilized cryoprecipitate (LPRC) that could expedite the early administration of cryoprecipitate in the battlefield. METHODS: A mouse multiple-trauma model with uncontrolled hemorrhage (UCH) from liver injury was utilized followed by hypotensive resuscitation (mean arterial pressure, 55-60) × 3 hours with lactated Ringer's (LR), fresh frozen plasma (FFP), conventional pathogen-reduced cryoprecipitate (CC), and LPRC. Blood was collected for measurement of syndecan-1, VWF, and ADAMTS13 by ELISA. Lungs were stained for histopathologic injury and syndecan-1 and bronchial alveolar lavage (BAL) fluid harvested for protein as an indicator of permeability. Statistical analysis was by ANOVA followed by Bonferroni correction. RESULTS: Following multiple trauma and UCH, blood loss was similar across groups. Mean volume of resuscitation was higher in the LR group compared with the other resuscitation groups. Lung histopathologic injury, syndecan-1 immunostaining and BAL protein were higher with LR compared with resuscitation with FFP and CC, while LPRC further reduced BAL compared with FFP and CC. The ADAMTS13/VWF ratio was significantly lower in LR but improved with FFP and CC, comparable to shams while LPRC further increased this ratio. CONCLUSION: The protective effects of CC and LPRC were comparable to FFP in ameliorating the EoT in our murine multiple trauma and UCH model. Lyophilized cryoprecipitate may also provide additional benefit by enhancing the ADAMTS13/VWF ratio. These data provide evidence of the safety and efficacy of LPRC and warrants further investigation for its potential application in military settings once approved for human administration.

BACKGROUND: Surgical rescue (SR) is the recovery of patients with surgical complications. Patients transferred (TP) for surgical diagnoses to higher-level care or inpatients (IP) admitted to nonsurgical services may develop intra-abdominal infection (IAI) and require emergency surgery (ES). The aims were to characterize the SR population by the site of ES consultation, open abdomen (OA), and risk of mortality. STUDY DESIGN: This was an international, multi-institutional prospective observational study of patients requiring ES for IAI. Laparotomy before the transfer was an exclusion criterion. Patients were divided into groups: clinic/ED (C/ED), IP, or TP. Data collected included demographics, the severity of illness (SOI), procedures, OA, and number of laparotomies. The primary outcome was mortality. Multivariable logistic regression models were constructed. RESULTS: There were 752 study patients (C/ED 63.8% vs TP 23.4% and IP 12.8%), with a mean age of 59 years and 43.6% women. IP had worse SOI scores (Charlson Comorbidity Index, American Society of Anesthesiologists Physical Status Classification System, and Sequential Organ Failure Assessment). The most common procedures were small and large bowel (77.3%). IP and TP had similar rates of OA (IP 52.1% and TP 52.3 %) vs C/ED (37.7%, p < 0.001), and IP had more relaparotomies (3 or 4). The unadjusted mortality rate was highest in IP (n = 24, 25.0%) vs TP (n = 29, 16.5%) and C/ED (n = 68, 14.2%, p = 0.03). Adjusting for age and SOI, only SOI had an impact on the risk of mortality (area under the curve 86%). CONCLUSIONS: IP had the highest unadjusted mortality after ES for IAI and was followed by the TP; SOI drove the risk of mortality. SR must be extended to IP for timely recognition of the IAI.

PURPOSE: Previous studies have shown older adults receive relatively less protection from seat belts against fatal injuries, however it is unknown how seat belt protection against severe and torso injury changes with age. We estimated age-based variability in seat belt protection against fatal injuries, injuries with maximum abbreviated injury scale greater than two (MAIS 3+), and torso injuries. METHODS: We leveraged the Crash Outcome Data Evaluation System to analyze binary indicators of fatal, MAIS 3+, and torso injuries. Using a matched cohort design and conditional Poisson regression, we estimated age-based relative risks (RR) of the outcomes associated with seat belt use. RESULTS: Our results suggested that seat belts were highly protective against fatal injuries for all ages. For ages 16-30, seat belt use was associated with 66% lower risk of MAIS3+ injury (RR 0.34, 95% CI 0.30, 0.38) for occupants of the same vehicle, whereas for ages 75 and older, seat belt use was associated with 38% lower risk of MAIS3+ injury (RR 0.62; 95% CI 0.45, 0.86) for occupants in the same vehicle. The association between restraint use and torso injury also attenuated with age. CONCLUSIONS: In multi-occupant crashes, seat belts were highly protective against fatal and MAIS3+ injury, however seat belt protection against MAIS3+ and torso injury attenuated with age.

BACKGROUND: It has been shown that microRNA-19b (miR-19b) binds to and degrades syndecan-1 after hemorrhagic shock (HS) and contributes to endothelial dysfunction in vitro and in vivo. The objective of the current study was to assess longitudinal changes in miR-19b and syndecan-1 in HS patients. METHODS: Blood samples from HS patients (blood pressure <90 mm Hg and ≥2 U blood) were collected upon admission, completion of hemostasis, and after 24 hours for miR-19b (quantitative reverse transcription PCR) and syndecan-1 (enzyme-linked immunosorbent assay) and compared with controls and minimally injured (Injury Severity Score, ≤9). Inflammatory cytokines were measured (Luminex [Thermo Fisher, Waltham, MA]). Correlations between syndecan-1, miR-19b, inflammatory markers, and patient outcomes were performed. Logistic regression models were developed for outcomes. RESULTS: Thirty-four HS patients were studied: age, 46 (19-89) years; male, 82%; penetrating, 35%; Injury Severity Score, 24 ± 10; and blood products at 24 hours, 21 ± 19 U. MicroRNA-19b was increased upon arrival and further increased over time: 4.6 â 6.7 â 24.1-fold change compared with 0.1 and 1.2 for minimally injured patients and controls, respectively. Syndecan-1 was increased to 42.6 â 50 â 51.5 ng/mL over time compared with 14.7 and 23.5 for minimally injured and controls, respectively. Values for both biomarkers remained significantly increased through 24 hours and were associated with a persistent increase in inflammatory cytokines. Admission syndecan-1 significantly predicted mortality, coagulopathy, and massive transfusion. CONCLUSION: We have shown for the first time that miR-19b and syndecan-1 were biomarkers for endothelial dysfunction independent of resuscitation. MicroRNA-19b did not demonstrate a strong correlation with syndecan-1 nor outcomes. Admission syndecan-1, however, remains a strong prognostic marker, but its elevation over time suggests a versatile role following HS that requires further investigation. LEVEL OF EVIDENCE: Prognostic/Epidemiological; Level II.

OBJECTIVE: Seat belt usage has increased substantially since the 1960s, yet driver use continues to affect passenger usage. Recent observational restraint use findings for Maryland will examine the relationship between driver and passenger usage, including adults and children in the rear seat. METHODS: Analyses were based on observational front and rear seat studies administered in parallel from 2016 to 2019. A statistically rigorous front seat project yielded weighted results among drivers and outboard passengers. A study of adults and children in the rear seat was based on a convenience sample of vehicles. Restraint usage results were presented as frequencies and proportions among occupants with known belt use, along with the 95% confidence interval for overall rates. RESULTS: Overall restraint usage rates averaged 90.9% in the front seat study and 81.1% in the rear seat sample. In vehicles with two front seat occupants and a belted driver, the proportion of belted passengers averaged 93.0% over four years. However, among unbelted drivers, only 41.6% of passengers were belted on average. In the rear seat study, an average of 82.7% were belted in vehicles driven by a restrained driver, differing for children (92.0%) versus adults (70.4%). Analysis of vehicles with an unbelted driver revealed an average of 45.0% of belted rear seat occupants, with a considerable difference for children (65.0%) compared with adults (21.0%). CONCLUSIONS: Observational seat belt studies in Maryland in recent years have shown that, despite overall rates above 80%, passenger use in both the front and rear seats is associated with driver restraint use.

OBJECTIVES: Describe the epidemiology of a large cohort of older adults with isolated traumatic brain injury (TBI) and identify predictors of mortality, palliative interventions, and discharge to preinjury residence in those presenting with moderate/severe TBI. DESIGN: Prospective observational study of geriatric patients with TBI enrolled across 45 trauma centers. SETTING AND PARTICIPANTS: Inclusion criteria were age ≥40 years, and computed tomography (CT)-verified TBI. Exclusion criteria were any other body region abbreviated injury scale score >2 and presentation at enrolling center >24 hours after injury. METHODS: The analysis was restricted to individuals aged ≥65 and stratified into 3 age groups: young-old (65-74), middle-old (75-84), and oldest-old (≥85). Demographic, clinical, and injury data were collected. Predictors of mortality, palliative interventions, and discharge to preinjury residence in the moderate/severe TBI group were identified using Classification and Regression Tree and Generalized Linear Mixed Models. RESULTS: Of the 3081 subjects enrolled in the study, 2028 were ≥65 years old. Overall, 339 (16.7%) presented with a moderate/severe TBI and experienced a 64% mortality rate. A Glasgow Coma Scale (GCS) score <9 was the main predictor of mortality, CT worsening (odds ratio [OR] = 1.7, P < .04), cerebral edema (OR = 2.4, P < .04), GCS <9, and age ≥75 (OR = 2.1, P = .007) were predictors for palliative interventions, and an injury severity score ≤24 (OR = 0.087, P = .002) was associated with increased likelihood of discharge to preinjury residence in the moderate/severe TBI group. CONCLUSION AND IMPLICATIONS: In this prospective study of a large cohort of older adults with isolated TBI, comparisons across the older age groups with moderate/severe TBI revealed that survival and favorable discharge disposition were influenced more by severity of injury rather than age itself. Indicating that chronological age alone maybe insufficient to accurately predict outcomes, and increased representation of older adults in TBI research to develop better diagnostic and prognostic tools is warranted.

OBJECTIVE: A decline in OHCA performance metrics during the pandemic has been reported in the literature but the cause is still not known. The Montgomery County Fire and Rescue Service (MCFRS) observed a decline in both the rate of return of spontaneous circulation (ROSC) and the proportion of resuscitations that resulted in cerebral performance category (CPC) 1 or 2 discharge of the patient beginning in March of 2020. This study examines whether the decline in these performance metrics persists when known COVID positive patients are excluded from the analysis. METHODS: Two samples of OHCA patients for similar time periods (one year apart) before and after the start of the COVID pandemic were developed. A database of known COVID positive patients among EMS encounters was used to identify and exclude COVID positive patients. OHCA outcomes in these two groups were then compared using a Chi-square test and Fisher's exact test for difference in proportions and Analysis of Variance (ANOVA) for difference in means. A two-stage multivariable logistic regression model was used to develop odds ratios for achieving ROSC and CPC 1 or 2 discharge in each period. RESULTS: After excluding known COVID patients, 32.5% of the patients in the pre-COVID period achieved ROSC compared to 25.1% in the COVID period (p = 0.007). 6% of patients in the pre-COVID period were discharged with CPC 1 or 2 compared to 3.2% from the COVID era (p = 0.026). Controlling for all available patient characteristics, patients undergoing OHCA resuscitation prior to be beginning of the pandemic were 1.2 times more likely to achieve ROSC and 1.6 times more likely to be discharged with CPC 1 or 2 than non-COVID patients in the pandemic era sample. CONCLUSIONS: When known COVID patients are excluded, pre-pandemic OHCA resuscitation patients were more likely to achieve ROSC and CPC 1 or 2 discharge. The prevalence of known COVID positive patients among all OHCA resuscitations during the pandemic was not sufficient to fully account for the marked decrease in both ROSC and CPC 1 or 2 discharges. Other causative factors must be sought.

Background: Early during the COVID-19 pandemic, Emergency Medical Services (EMS) systems encountered many challenges that prompted crisis-level strategies. Maryland's statewide EMS system implemented the Viral Syndrome Pandemic Triage Protocol which contained a decision tool to help identify patients potentially safe for self-care at home. Objectives: This study assessed the effects of the Maryland Viral Syndrome Pandemic Triage Protocol and the safety of referring patients for self-care at home. Methods: This is a retrospective statewide analysis of EMS patients from March 19 thru September 4, 2020, who were not transported and had documentation of the Viral Syndrome Pandemic Triage Protocol's decision support tool completed, as well as a random sample of 150 patients who were not transported and did not have documentation of the decision tool. Descriptive statistics were performed as well as a two-stage multivariable logistic regression model for the outcomes of ED presentation within 24 hours and subsequent hospitalization. Results: 301 EMS patients were documented as triaged to home using the protocol and outcomes data were available for 282 (94%). 41(14.5%) patients presented to an ED within 24 hours and 14 (5% of 282) required inpatient hospitalization. Nine (3.2%) patients were subsequently hospitalized with a diagnosis of COVID-19 illness. Of those patients for whom the decision tool was not documented, 35 (23%) had an ED visit within 24 hours and 15 (10%) were hospitalized (p = 0.075). Multivariate logistic regression model results (N = 432) suggest that those with documentation of triage protocol use had some advantage over those patients without documentation. The 95% CIs of the estimated effect of Triage/No Triage protocol documented were wide and crossed the 1.0 limit but overall, all effects Odds Ratios and Adjust Odds Ratios were consistently over 1.0 with the lowest value of 1.3 and the highest value of 2.1. Conclusion: Most patients (95%) who were triaged to self-care at home with home documented decision support tool use did not require hospitalization within 24 hours following EMS encounter and this appears to be safe. Future opportunity exists to incorporate such tools into comprehensive pandemic preparedness strategies along with appropriate follow up and quality improvement mechanisms.

BACKGROUND: A life-threatening complication of coronavirus disease 2019 (COVID-19) is acute respiratory distress syndrome (ARDS) refractory to conventional management. Venovenous (VV) extracorporeal membrane oxygenation (ECMO) (VV-ECMO) is used to support patients with ARDS in whom conventional management fails. Scoring systems to predict mortality in VV-ECMO remain unvalidated in COVID-19 ARDS. This report describes a large single-center experience with VV-ECMO in COVID-19 and assesses the utility of standard risk calculators. METHODS: A retrospective review of a prospective database of all patients with COVID-19 who underwent VV-ECMO cannulation between March 15 and June 27, 2020 at a single academic center was performed. Demographic, clinical, and ECMO characteristics were collected. The primary outcome was in-hospital mortality; survivor and nonsurvivor cohorts were compared by using univariate and bivariate analyses. RESULTS: Forty patients who had COVID-19 and underwent ECMO were identified. Of the 33 patients (82.5%) in whom ECMO had been discontinued at the time of analysis, 18 patients (54.5%) survived to hospital discharge, and 15 (45.5%) died during ECMO. Nonsurvivors presented with a statistically significant higher Prediction of Survival on ECMO Therapy (PRESET)-Score (mean ± SD, 8.33 ± 0.8 vs 6.17 ± 1.8; P = .001). The PRESET score demonstrated accurate mortality prediction. All patients with a PRESET-Score of 6 or lowers survived, and a score of 7 or higher was associated with a dramatic increase in mortality. CONCLUSIONS: These results suggest that favorable outcomes are possible in patients with COVID-19 who undergo ECMO at high-volume centers. This study demonstrated an association between the PRESET-Score and survival in patients with COVID-19 who underwent VV-ECMO. Standard risk calculators may aid in appropriate selection of patients with COVID-19 ARDS for ECMO.

Background: Excessive alcohol use is a risk factor for injury-related deaths. Postmortem blood samples are commonly used to approximate antemortem blood alcohol concentration (BAC) levels.Objectives: To assess differences between antemortem and postmortem BACs among fatally injured adults admitted to one shock trauma center (STC).Method: Fifty-two adult decedents (45 male, 7 female) admitted to a STC in Baltimore, Maryland during 2006-2016 were included. STC records were matched with records from Maryland's Office of the Chief Medical Examiner (OCME). The antemortem and postmortem BAC distributions were compared. After stratifying by antemortem BACs <0.10 versus ≥0.10 g/dL, differences in postmortem and antemortem BACs were plotted as a function of length of hospital stay.Results: Among the 52 decedents, 22 died from transportation-related injuries, 20 died by homicide or intentional assault, and 10 died from other injuries. The median BAC antemortem was 0.10 g/dL and postmortem was 0.06 g/dL. Thirty-one (59.6%) decedents had antemortem BACs ≥0.08 g/dL versus 22 (42.3%) decedents using postmortem BACs. Postmortem BACs were lower than the antemortem BACs for 42 decedents, by an average of 0.07 g/dL. Postmortem BACs were higher than the antemortem BACs for 10 decedents, by an average of 0.06 g/dL.Conclusion: Postmortem BACs were generally lower than antemortem BACs for the fatally injured decedents in this study, though not consistently. More routine antemortem BAC testing, when possible, would improve the surveillance of alcohol involvement in injuries. The findings emphasize the usefulness of routine testing and recording of BACs in acute care facilities.

BACKGROUND: A previous single-center survey of trauma and general surgery faculty demonstrated perceived positive impact of trauma and surgical subspecialty service-based advanced practice providers (SB APPs). The aim of this multicenter survey was to further validate these findings. METHODS: Faculty surgeons on teams that employ SB APPs at 8 academic centers completed an electronic survey querying perception about advanced practice provider (APP) competency and impact. RESULTS: Respondents agreed that SB APPs decrease workload (88%), length of stay (72%), contribute to continuity (92%), facilitate care coordination (87%), enhance patient satisfaction (88%), and contribute to best practice/safe patient care (83%). Fewer agreed that APPs contribute to resident education (50%) and quality improvement (QI)/research (36%). Although 93% acknowledged variability in the APP level of function, 91% reported trusting their clinical judgment. CONCLUSION: This study supports the perception that SB APPs have a positive impact on patient care and quality indicators. Areas for potential improvement include APP contribution to resident education and research/QI initiatives.

BACKGROUND: COPD patients account for a large proportion of lung transplants; lung transplantation survival benefit for COPD patients is not well established. METHODS: We identified 4521 COPD patients in the United Network for Organ Sharing (UNOS) dataset transplanted from May 2005 to August 2016, and 604 patients assigned to receive pulmonary rehabilitation and medical management in the National Emphysema Treatment Trial (NETT). After trimming the populations for NETT eligibility criteria and data completeness, 1337 UNOS and 596 NETT patients remained. Kaplan-Meier estimates of transplant-free survival from transplantation for UNOS, and NETT randomisation, were compared between propensity score-matched UNOS (n=401) and NETT (n=262) patients. RESULTS: In propensity-matched analyses, transplanted patients had better survival compared to medically managed patients in NETT (p=0.003). Stratifying on 6â min walk distance (6â MWD) and FEV1, UNOS patients with 6â MWD <1000â ft (â¼300â m) or FEV1 <20% of predicted had better survival than NETT counterparts (median survival 5.0â years UNOS versus 3.4â years NETT; log-rank p<0.0001), while UNOS patients with 6â MWD ≥1000â ft (â¼300â m) and FEV1 ≥20% had similar survival to NETT counterparts (median survival, 5.4â years UNOS versus 4.9â years NETT; log-rank p=0.73), interaction p=0.01. CONCLUSIONS: Overall survival is better for matched lung transplant patients compared with medical management alone. Patients who derive maximum benefit are those with 6â MWD <1000â ft (â¼300â m) or FEV1 <20% of predicted, compared with pulmonary rehabilitation and medical management.
