RESUMO

OBJECTIVES: Data regarding retrograde open mesenteric stenting (ROMS) for urgent mesenteric ischemia is limited to small single center and case series, with variable utilization across patient populations and ill-defined outcomes. We aimed to evaluate characteristics and outcomes of patients with acute mesenteric ischemia requiring urgent surgical intervention. METHODS: Retrospective cohort study of patients with mesenteric ischemia requiring urgent surgical intervention from 2018 to 2020 was queried from the National Inpatient Sample (NIS) database. Study groups were defined as those requiring an open bypass (BYPASS), an open superior mesenteric artery embolectomy (OPEN), or ROMS. Descriptive statistics were used to report variables. Comparisons were mad using t test, chi-squares tests, and multivariate regression reported as odds ratio (OR), 95% confidence interval (CI) where appropriate. RESULTS: 898 patients with mesenteric ischemia requiring urgent surgical intervention were included: Bypass: 284, OPEN: 363, ROMS: 251. There was no difference in gender or race between groups. Patients requiring ROMS were more likely to be older 70.2 + 11.3versus Bypass 66.81 + 11.6 and OPEN 67.17 + 14.5, p = 0.0035. ROMS patients had the highest Charlson Comorbidity Index (CCI) 2.9 versus 2.5 Bypass and 2.6 OPEN, p = 0.0292 with the most frequent comorbidities: Diabetes 37% (p = 0.01), renal disease 24.3% (p = 0.5), and previous preoperative myocardial infarction 9.2%, p = 0.05; however, the lowest mortality rate was seen within this Group 15.9% versus bypass 19.7%, OPEN 34.5%, p < 0.0001. Patients requiring bypass were more likely to have chronic pulmonary disease 34.5% versus OPEN 24.2% and ROMS 31.5%, p = 0.013, peripheral vascular disease (PVD) 38% versus OPEN 16%, and ROMS 29.9%, p < 0.0001. On multivariate regression, ROMS was associated with 50% decreased incidence of mortality (OR 0.45, 95% CI 0.27-0.75). Open SMA embolectomy was associated with nearly 2x mortality rate compared to bypass procedures OR 2.0, 95% CI 1.3-3.0, p < 0.001. Previous MI was also associated with nearly 2x incidence of mortality (OR 1.9, 95% CI 1.01-3.6), while pre-existing PVD conferred a protective effect (OR 0.56, 95% CI 0.36-0.89). Higher CCI and age were associated with slightly increased risk for mortality OR 1.2 and 1.03, p < 0.05 for both. CONCLUSIONS: In patients with acute mesenteric ischemia, ROMS demonstrated a significant mortality benefit compared to traditional open procedures. Advanced age, history of MI, and open SMA embolectomy were associated with increased mortality. Little data exists regarding ROMS in a real-world population evaluating ROMS, which is a newer technique. These data suggest that ROMS may be a superior alternative to restore mesenteric flow in the acute setting and further prospective studies evaluating ROMS to other procedural types in urgent and elective settings are needed.

RESUMO

OBJECTIVES: Patency for chronic total occlusions (CTO) of the superficial femoral artery (SFA) after endovascular interventions traditionally demonstrate a low 1-year patency ranging from 40%-60%. The optical coherence tomography (OCT) catheter (Avinger Inc., Redwood City, CA) uses light-based technology imaging to cross Trans-Atlantic Inter-Society Consensus D (TASC D) lesions intraluminally with direct intra-arterial visualization. Insufficient data exist evaluating intraluminal crossing with OCT imaging compared with traditional subintimal techniques. We evaluated outcomes for TASC D lesions crossed intraluminally. METHODS: A retrospective analysis of patients with SFA TASC D lesions crossed intra-arterially with the OCT catheter imaging. Descriptive statistics evaluated patient characteristics which included patient demographics, Rutherford scores, ABIs, CTA information, lesion categorization, as well as runoff score. Patency at baseline, 30-day, 6-month, and 1-year outcomes were compared using t-tests. Cumulative patency rates were evaluated using Kaplan-Meier analysis. RESULTS: 101 patients underwent elective intervention for SFA TASC D lesions with the OCT catheter. The crossing rate was 78.2%, mean lesion length was 16.2 cm, and runoff at the tibial level was 2.2 patent vessels. Mean age and BMI were 64 years and 29 kg/m2, respectively. Patient characteristics are male (57%); Caucasian (90%); ever smoking (85%); hypertension (82%), hyperlipidemia (70%), and diabetes (46%). Pre-operative computed tomography demonstrated SFA lesions were predominantly eccentric (91%) with mild to moderate calcification (90%). All underwent PTA, 87% were stented (mean stent length: 186.1 mm), mean crossing time was 13.4 min. Pre-operative, 30-day, 6-month, and 1-year post-operative mean Rutherford-Becker scores were 4, 1, 1, and 1, respectively (p < 0.0001). Mean pre-operative ABI was 0.49, compared to 0.84 at 30 days, 0.64 at 6 months, and 0.67 at 1 year (p < .0001). Duplex demonstrated 6- and 12-month primary patency of 89% and 75%; primary-assisted patency was 94% and 84%. CONCLUSIONS: The OCT imaging catheter successfully crossed long chronic total occlusions of the SFA using direct intra-arterial imaging. Compared to subintimal techniques, patients had high 1-year primary patency and prolonged symptom improvement with intraluminal crossing. These data suggest that intraluminal crossing of TASC D lesions may be superior to traditional subintimal crossing techniques.

RESUMO

INTRODUCTION: Failure to Rescue (FTR), defined as mortality following a complication of care, is an important indicator of hospital care quality. Understanding risk factors associated with FTR in the elective Abdominal Aortic Aneurysm (AAA) population may help surgeons prevent operative mortality. METHODS: Elective open AAA repairs (2008-2018) were identified from Cerner's HealthFacts database using ICD-9 and ICD-10 diagnosis and procedure codes. Patient, hospital, and encounter characteristics were analyzed. Multivariate logistic regression models determined the relative contribution of patient and encounter characteristics leading to FTR. RESULTS: For 1761 patients who underwent open repair for nonruptured AAA, overall mortality was 6.1%. Of patients with one or more complications (40%), mortality was 9.6%, increasing to 21.5% for patients with ≥4 major complications. Complications of care most associated with death were myocardial infarction (MI), gastrointestinal (GI) bleeding, and pulmonary failure. After multivariable adjustment, FTR was associated with advanced age (odds ratio [OR] 1.19 for 5 y, 95% confidence interval [CI] 1.06-1.34); female sex (OR 1.74, 95% CI 1.12-2.70); congestive heart failure (OR 1.65, 95% CI 1.00-2.73); peptic ulcer disease (OR 3.99, 95% CI 1.18-13.5); diabetes (OR 4.90, 95% CI 1.90-12.6), and the number of complications of care. CONCLUSIONS: Complications of care were common following open elective AAA repair. The complications with the highest mortality included MI, GI bleeding, and respiratory failure. FTR was associated with female sex, comorbidities, and increasing numbers of complications of care. Often, the lowest occurring complications had the highest FTR. Adopting gender-specific assessment tools, a protocol-driven approach for perioperative GI prophylaxis, and preoperative MI risk mitigation may lead to reduced FTR.

RESUMO

OBJECTIVES: Opioids are commonly used for pain control after lower extremity amputations (LEA)-below the knee amputations (BKA) and above the knee amputations (AKA). Well-defined benchmarks for prescription requirements after amputation are deficient. This analysis evaluated opioid utilization after amputation to identify high-risk patients and provide recommendations for post-hospitalization opioid prescriptions at discharge. METHODS: Patients undergoing LEA (2008-2016) with identified peripheral vascular disease were selected from Cerner's Health Facts® database using ICD-9 and 10 diagnosis and procedure codes. Patient demographics, disease severity, comorbidities, and hospital characteristics were evaluated. Post-operative opioid medications administered intravenously and orally during the hospital stay were identified from the data and converted to Morphine Milligram Equivalent per day (MME/d) for an evaluation and comparison during the index hospitalization. Descriptive statistics were used to report continuous and dichotomous variables. Dichotomous variables are reported as n (%) and continuous variables are reported as mean ± standard deviation (SD). Chi-square and T-tests were used as appropriate. RESULTS: 2399 patients who underwent AKA or BKA with peripheral vascular disease were evaluated. Sixty-three percent of the cohort was male, 67% Caucasian, and 42% married, and 58% had a Charlson index >3. The majority of patients had an average length of hospital stay of 5.7 days (M = 5.72, SD = 4.56). Patient groups that used significantly higher MME/d in the early postop period included: BKA (29.2 vs 20.7, p = 0.006), males (62.6 vs 54.0, p < 0.0001), Caucasians (64.3 vs 44.7, p < 0.0001), younger patients (69.6 vs 54.0, p < 0.0001), and those at non-training institutions (66.7 vs 56.7, p < 0.0001). Patients whose hospital stay was greater than 6 days were found to have increased opioid utilization likely secondary to index complications. For those discharged by post-operative day 7, the mean MME utilized on postop day 1 was 59.5 and decreased to a mean MME/d utilization prior to discharge of 17.6. CONCLUSIONS: This analysis demonstrates that younger patients, males, patients with BKAs, and those who receive amputations for vascular disease at non-training institutions have higher post-operative opioid utilization during the hospital stay. At the time of discharge, patients utilized an average of 17.6 MME/d which equates to approximately three hydrocodone/acetaminophen 5/325 mg tablets per day. Based on these findings, vascular surgeons are likely over prescribing opioids at discharge and must be cognizant of appropriate dosing quantities. Prescriptions at discharge should reflect the daily utilization described from this analysis and tapered to avoid chronic utilization, overdose, and possible death.

RESUMO

Vascular surgery patients have a high incidence of unplanned hospital readmissions and complications. Previous research has not fully examined specific elements of the hospital discharge process for vascular surgery patients to identify issues that may contribute to readmissions. The objective of this qualitative descriptive study was to explore challenges identified by healthcare providers and patients regarding the discharge process from an academic vascular surgery service. Data were collected from eight focus group interviews and analyzed for relevant themes. Patients and healthcare providers identified several challenges within the standard discharge process, including ineffective communication, insufficient time for discharge education, and limitations accessing providers with post-discharge concerns. These obstacles may be ameliorated in part by specialized coordinators, caregiver support, and use of adaptive strategies outside of the current discharge process. The discharge challenges described by study participants likely contribute to adverse post-hospitalization outcomes, including unplanned hospital readmissions. A multifaceted approach that incorporates standardized discharge processes, as well as informal problem-solving strategies, is recommended to improve hospital discharge and outcomes for vascular surgery patients.

RESUMO

BACKGROUND: Fenestrated endovascular aneurysm repair (FEVAR) has emerged as a minimally invasive alternative for repairing complex abdominal aortic aneurysms (AAA). Comparisons of outcomes for FEVAR and traditional endovascular aneurysm repair (EVAR) are limited. We evaluated outcomes following elective endovascular AAA repair with FEVAR or EVAR. METHODS: Hospitalizations for elective nonruptured AAA repair from 2014 to 2016 were selected from the Nationwide Readmissions Database (NRD) using ICD-9 and ICD-10 procedure and diagnosis codes. In-hospital mortality, length of stay (LOS), complications, 30-day readmission, and charges were evaluated. Multivariable logistic regression was used to control for confounding between groups. RESULTS: We identified 23,262 EVAR and 2,373 FEVAR with nonruptured elective procedures. In-hospital mortality was 0.14% for both groups (P = 0.99). Of those at risk for readmission (21,152 EVAR, 1,915 FEVAR), index LOS was greater for FEVAR compared to EVAR, 1.8 days versus 1.7 days (P = 0.028). There was no difference in procedure type based on hospital location (P = 0.37), teaching status (P = 0.17) or hospital size (P = 0.26). During the index hospitalization, pneumonia, renal, and respiratory complications were similar between groups (all P > 0.05). FEVAR patients were more likely to experience cardiac complications (P = 0.0098) or hemorrhage (P = 0.029). Total charges for the index stay were greater for FEVAR compared to EVAR ($125,381 vs. $113,513, P < 0.0001). All-cause 30-day readmission was similar between groups (7.0% EVAR vs. 8.0% FEVAR, P = 0.37), as were time to readmission (11.9 vs. 13.3 days, P = 0.16) and readmission charges ($53,967 vs. $56,617, P = 0.75). Renal failure was the most common readmission stay complication, with similar rates for EVAR and FEVAR patients (P = 0.22). Pneumonia was a more common complication during the readmission stay for EVAR patients (P = 0.004). Renal disease and chronic pulmonary disease were the most common comorbidities in the readmission stay for both groups. CONCLUSIONS: For patients with nonruptured elective AAA, FEVAR was not associated with increased mortality, length of stay, readmission, or most complications compared to traditional EVAR. Despite the increased technical complexity of cannulating and stenting visceral arteries with FEVAR, these data demonstrate that FEVAR carries a similar risk of renal, respiratory, and infectious complications compared to traditional EVAR. FEVAR patients were more likely to experience hemorrhagic and cardiac complications during the index hospitalization. EVAR patients were more likely to have pneumonia during readmission. The overall risk for readmission after an endovascular aortic repair was associated with female sex, greater age, chronic pulmonary disease, malignancy, and loss of function. Further investigations into the causes and prevention of 30-day readmissions are needed for both procedures.

RESUMO

OBJECTIVE: Transition from the hospital to an outpatient setting is a multifaceted process requiring coordination among a variety of services and providers to ensure a high-quality discharge. Vascular surgery patients comprise a complex population that experiences high unplanned readmission rates. We performed a qualitative study to identify themes for process improvement for vascular surgery patients. A validated discharge process, RED (Re-Engineered Discharge), was used to identify additional actionable themes to create a more efficient discharge process tailored specifically to the vascular surgery population. METHODS: A prospective, qualitative analysis at a tertiary center using a semi-structured focus group interview guide was performed to evaluate the current discharge process and identify opportunities for improvement. Focus groups were Zoom recorded, transcribed into electronic text files, and were loaded into Dedoose qualitative software for analysis using a directed content analysis approach. Two researchers independently thematically coded each transcript, starting with accepted discharge components to identify new thematic categories. Prior to analysis, all redundancy of codes was resolved, and all team members agreed on text categorization and coding. RESULTS: Eight focus groups with a total of 38 participants were conducted. Participants included physicians (n = 13), nursing/ancillary staff (n = 14), advanced nurse practitioners (n = 2), social worker/dietitian/pharmacist (n = 3), and patients (n = 6). Transcript analyses revealed facilitators and barriers to the discharge process. In addition to traditional RED components, unique concepts pertinent to vascular surgery patients included patient complexity, social determinants of health, technology literacy, complexity of ancillary services, discharge appropriateness, and use of advanced nurse practitioners for continuity. CONCLUSIONS: Specific themes were identified to target and enhance the future vRED (vascular Re-Engineered Discharge) bundle. Thematic targets for improvement include increased planning, organization, and communication prior to discharge to address vascular surgery patients' multiple comorbidities, extensive medication lists, and need for complex ancillary services at the time of discharge. Other thematic barriers discovered to improve include provider awareness of patient health literacy, patient understanding of complex discharge instructions, patient technology barriers, and intrinsic social determinants of health in this population. To address these discovered barriers, organizational targets to improve include enhanced social support, the use of advanced nurse practitioners for education reinforcement, and increased coordination. These results provide a framework for future quality improvement targeting the vascular surgery discharge process.

RESUMO

Recent use of noninvasive and continuous hemoglobin (SpHb) concentration monitor has emerged as an alternative to invasive laboratory-based hematological analysis. Unlike delayed laboratory based measures of hemoglobin (HgB), SpHb monitors can provide real-time information about the HgB levels. Real-time SpHb measurements will offer healthcare providers with warnings and early detections of abnormal health status, e.g., hemorrhagic shock, anemia, and thus support therapeutic decision-making, as well as help save lives. However, the finger-worn CO-Oximeter sensors used in SpHb monitors often get detached or have to be removed, which causes missing data in the continuous SpHb measurements. Missing data among SpHb measurements reduce the trust in the accuracy of the device, influence the effectiveness of hemorrhage interventions and future HgB predictions. A model with imputation and prediction method is investigated to deal with missing values and improve prediction accuracy. The Gaussian process and functional regression methods are proposed to impute missing SpHb data and make predictions on laboratory-based HgB measurements. Within the proposed method, multiple choices of sub-models are considered. The proposed method shows a significant improvement in accuracy based on a real-data study. Proposed method shows superior performance with the real data, within the proposed framework, different choices of sub-models are discussed and the usage recommendation is provided accordingly. The modeling framework can be extended to other application scenarios with missing values.

RESUMO

BACKGROUND: People living with human immunodeficiency virus (HIV) may have numerous risk factors for acquiring coronavirus disease 2019 (COVID-19) and developing severe outcomes, but current data are conflicting. METHODS: Health-care providers enrolled consecutively, by nonrandom sampling, people living with HIV (PWH) with lab-confirmed COVID-19, diagnosed at their facilities between 1 April and 1 July 2020. Deidentified data were entered into an electronic Research Electronic Data Capture (REDCap) system. The primary endpoint was a severe outcome, defined as a composite endpoint of intensive care unit (ICU) admission, mechanical ventilation, or death. The secondary outcome was the need for hospitalization. RESULTS: There were 286 patients included; the mean age was 51.4 years (standard deviation, 14.4), 25.9% were female, and 75.4% were African American or Hispanic. Most patients (94.3%) were on antiretroviral therapy, 88.7% had HIV virologic suppression, and 80.8% had comorbidities. Within 30 days of testing positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), 164 (57.3%) patients were hospitalized, and 47 (16.5%) required ICU admission. Mortality rates were 9.4% (27/286) overall, 16.5% (27/164) among those hospitalized, and 51.5% (24/47) among those admitted to an ICU. The primary composite endpoint occurred in 17.5% (50/286) of all patients and 30.5% (50/164) of hospitalized patients. Older age, chronic lung disease, and hypertension were associated with severe outcomes. A lower CD4 count (<200 cells/mm3) was associated with the primary and secondary endpoints. There were no associations between the ART regimen or lack of viral suppression and the predefined outcomes. CONCLUSIONS: Severe clinical outcomes occurred commonly in PWH with COVID-19. The risks for poor outcomes were higher in those with comorbidities and lower CD4 cell counts, despite HIV viral suppression. CLINICAL TRIALS REGISTRATION: NCT04333953.

RESUMO

BACKGROUND: Currently 20-35% of pregnant women are obese, posing a major health risk for mother and fetus. It is postulated that an abnormal maternal-fetal nutritional environment leads to adverse metabolic programming, resulting in altered substrate metabolism in the offspring and predisposing to risks of obesity and diabetes later in life. Data indicate that oocytes from overweight animals have abnormal mitochondria. We hypothesized that maternal obesity is associated with altered mitochondrial function in healthy neonatal offspring. METHODS: Overweight and obese (body mass index, (BMI) ≥ 25 kg/m2, n = 14) and lean (BMI < 25 kg/m2, n = 8), African-American pregnant women carrying male fetuses were recruited from the Barnes Jewish Hospital obstetric clinic. Maternal and infant data were extracted from medical records. Infants underwent body composition testing in the first days of life. Circumcision skin was collected for isolation of fibroblasts. Fibroblast cells were evaluated for mitochondrial function, metabolic gene expression, nutrient uptake, and oxidative stress. RESULTS: Skin fibroblasts of infants born to overweight mothers had significantly higher mitochondrial respiration without a concurrent increase in ATP production, indicating mitochondrial inefficiency. These fibroblasts had higher levels of reactive oxygen species and evidence of oxidative stress. Evaluation of gene expression in offspring fibroblasts revealed altered expression of multiple genes involved in fatty acid and glucose metabolism and mitochondrial respiration in infants of overweight mothers. CONCLUSIONS: This study demonstrates altered mitochondrial function and oxidative stress in skin fibroblasts of infants born to overweight mothers. Future studies are needed to determine the long-term impact of this finding on the metabolic health of these children.

RESUMO

OBJECTIVE: To determine if the use of fresh frozen plasma/frozen plasma 24 hours compared to solvent detergent plasma is associated with international normalized ratio reduction or ICU mortality in critically ill children. DESIGN: This is an a priori secondary analysis of a prospective, observational study. Study groups were defined as those transfused with either fresh frozen plasma/frozen plasma 24 hours or solvent detergent plasma. Outcomes were international normalized ratio reduction and ICU mortality. Multivariable logistic regression was used to determine independent associations. SETTING: One hundred one PICUs in 21 countries. PATIENTS: All critically ill children admitted to a participating unit were included if they received at least one plasma unit during six predefined 1-week (Monday to Friday) periods. All children were exclusively transfused with either fresh frozen plasma/frozen plasma 24 hours or solvent detergent plasma. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: There were 443 patients enrolled in the study. Twenty-four patients (5%) were excluded because no plasma type was recorded; the remaining 419 patients were analyzed. Fresh frozen plasma/frozen plasma 24 hours group included 357 patients, and the solvent detergent plasma group included 62 patients. The median (interquartile range) age and weight were 1 year (0.2-6.4) and 9.4 kg (4.0-21.1), respectively. There was no difference in reason for admission, severity of illness score, pretransfusion international normalized ratio, or lactate values; however, there was a difference in primary indication for plasma transfusion (p < 0.001). There was no difference in median (interquartile range) international normalized ratio reduction, between fresh frozen plasma/frozen plasma 24 hours and solvent detergent plasma study groups, -0.2 (-0.4 to 0) and -0.2 (-0.3 to 0), respectively (p = 0.80). ICU mortality was lower in the solvent detergent plasma versus fresh frozen plasma/frozen plasma 24 hours groups, 14.5% versus 29.1%%, respectively (p = 0.02). Upon adjusted analysis, solvent detergent plasma transfusion was independently associated with reduced ICU mortality (odds ratio, 0.40; 95% CI, 0.16-0.99; p = 0.05). CONCLUSIONS: Solvent detergent plasma use in critically ill children may be associated with improved survival. This hypothesis-generating data support a randomized controlled trial comparing solvent detergent plasma to fresh frozen plasma/frozen plasma 24 hours.

RESUMO

BACKGROUND: Prehospital identification of the injured patient likely to require emergent care remains a challenge. End-tidal carbon dioxide (ETCO2) has been used in the prehospital setting to monitor respiratory physiology and confirmation of endotracheal tube placement. Low levels of ETCO2 have been demonstrated to correlate with injury severity and mortality in a number of in-hospital studies. We hypothesized that prehospital ETCO2 values would be predictive of mortality and need for massive transfusion (MT) in intubated patients. METHODS: This was a retrospective multicenter trial with 24 participating centers. Prehospital, emergency department, and hospital values were collected. Receiver operating characteristic curves were created and compared. Massive transfusion defined as >10 U of blood in 6 hours or death in 6 hours with at least 1 U of blood transfused. RESULTS: A total of 1,324 patients were enrolled. ETCO2 (area under the receiver operating characteristic curve [AUROC], 0.67; confidence interval [CI], 0.63-0.71) was better in predicting mortality than shock index (SI) (AUROC, 0.55; CI, 0.50-0.60) and systolic blood pressure (SBP) (AUROC, 0.58; CI, 0.53-0.62) (p < 0.0005). Prehospital lowest ETCO2 (AUROC, 0.69; CI, 0.64-0.75), SBP (AUROC, 0.75; CI, 0.70-0.81), and SI (AUROC, 0.74; CI, 0.68-0.79) were all predictive of MT. Analysis of patients with normotension demonstrated lowest prehospital ETCO2 (AUROC, 0.66; CI, 0.61-0.71), which was more predictive of mortality than SBP (AUROC, 0.52; CI, 0.47-0.58) or SI (AUROC, 0.56; CI, 0.50-0.62) (p < 0.001). Lowest prehospital ETCO2 (AUROC, 0.75; CI, 0.65-0.84), SBP (AUROC, 0.63; CI, 0.54-0.74), and SI (AUROC, 0.64; CI, 0.54-0.75) were predictive of MT in normotensive patients. ETCO2 cutoff for MT was 26 mm Hg. The positive predictive value was 16.1%, and negative predictive value was high at 98.1%. CONCLUSION: Prehospital ETCO2 is predictive of mortality and MT. ETCO2 outperformed traditional measures such as SBP and SI in the prediction of mortality. ETCO2 may outperform traditional measures in predicting need for transfusion in occult shock. LEVEL OF EVIDENCE: Diagnostic test, level III.

RESUMO

The time interval between the peaks in the electroccardiogram (ECG) and ballistocardiogram (BCG) waveforms, TEB, has been associated with the pre-ejection period (PEP), which is an important marker of ventricular contractility. However, the applicability of BCG-related markers in clinical practice is limited by the difficulty to obtain a replicable and consistent signal on patients. In this study, we test the feasibility of BCG measurements within a complex clinical setting, by means of an accelerometer under the head pillow of patients admitted to the Surgical Intensive Care Unit (SICU). The proposed technique proved capable of capturing TEB based on the R peaks in the ECG and the BCG in its head-to-toe and dorso- ventral directions. TEB detection was found to be consistent and repeatable both in healthy individuals and SICU patients over multiple data acquisition sessions. This work provides a promising starting point to investigate how TEB changes may relate to the patients' complex health conditions and give additional clinical insight into their care needs.

RESUMO

Background: Although single-incision endoscopic splenectomy (SIES-Sp) has been shown to be feasible and safe, few have compared the SIES-Sp with multiport laparoscopic splenectomy (MPLS). The purpose of this study was to compare the two techniques in children undergoing total splenectomy. Materials and Methods: We reviewed all children (age <18 years) who underwent minimally invasive total splenectomy at a single tertiary referral center from January 1, 2000 to January 1, 2019. The primary outcome was complication rate 30 days after discharge defined by maximum Clavien-Dindo score. Secondary outcomes included conversion, operative time, hospital length of stay, postoperative pain scores, and readmission within 30 days of discharge. SIES-Sp and MPLS were compared using univariate analysis. Results: Of 48 children undergoing laparoscopic total splenectomy, 60% (n = 29) were SIES-Sp and 40% (n = 19) were MPLS. Subjects were 48% female (n = 23). Common diagnoses were idiopathic thrombocytopenic purpura (33% [n = 16]), hereditary spherocytosis (29% [n = 14]), and other congenital hemolytic anemias (23% [n = 11]). There were no differences in age, gender, or diagnosis between groups (all P > .05). One in three cases involved additional procedures. Spleens were smaller in both greatest dimension (13.0 cm versus 16.4 cm) and weight (156.5 g versus 240.0 g) in SIES-Sp compared with MPLS patients (both P < .05). Readmission and reoperation rates were similar (both P > .05). Complications occurred in 7% (n = 2) of SIES-Sp and in 11% (n = 2) of MPLS patients (P > .99). Severe complications included: cardiac arrest in 1 SIES-Sp patient and bleeding requiring reoperation in 1 MPLS patient. Conclusion: SIES-Sp is a safe alternative to the traditional MPLS for children. Additional procedures do not preclude a less invasive approach, but larger spleens may present a challenge.

RESUMO

BACKGROUND: Antimicrobial guidance for common bile duct (CBD) stones is limited. We sought to examine the effect of antibiotic duration on infectious complications in patients with choledocholithiasis and/or gallstone pancreatitis. METHODS: We performed a post hoc analysis of a prospective, observational, multicenter study of patients undergoing same admission cholecystectomy for choledocholithiasis and gallstone pancreatitis between 2016 and 2019. We excluded patients with cholangitis and/or cholecystitis. Patients were divided into groups based on duration of antibiotics: prophylactic (<24 hours) or prolonged (≥24 hours). We analyzed these two groups in the preoperative and postoperative periods. Outcomes included infectious complications, acute kidney injury (AKI), and hospital length of stay (LOS). RESULTS: There were 755 patients in the cohort. Increasing age, CBD diameter, and a preoperative endoscopic retrograde cholangiopancreatography (odds ratio, 1.91; 95% confidence interval, 1.34-2.73; p < 0.001) significantly predicted prolonged preoperative antibiotic use. Increasing age, operative duration, and a postoperative endoscopic retrograde cholangiopancreatography (odds ratio, 4.8; 95% confidence interval, 1.85-13.65; p < 0.001) significantly predicted prolonged postoperative antibiotic use. Rates of infectious complications were similar between groups, but LOS was 2 days longer for patients receiving overall prolonged antibiotics (p < 0.0001). Patients with AKI received two more days of overall antibiotic therapy (p = 0.02) compared with those without AKI. CONCLUSION: Rates of postoperative infectious complications were similar among patients treated with a prolonged or prophylactic course of antibiotics. Prolonged antibiotic use was associated with a longer LOS and AKI. LEVEL OF EVIDENCE: Therapeutic, Level IV.

RESUMO

OBJECTIVES: To characterize patterns of surgery among pediatric patients during terminal hospitalizations in children's hospitals. METHODS: We reviewed patients ≤20 years of age who died among 4 424 886 hospitalizations from January 2013-December 2019 within 49 US children's hospitals in the Pediatric Health Information System database. Surgical procedures, identified by International Classification of Diseases procedure codes, were classified by type and purpose. Descriptive statistics characterized procedures, and hypothesis testing determined if undergoing surgery varied by patient age, race and ethnicity, or the presence of chronic complex conditions (CCCs). RESULTS: Among 33 693 terminal hospitalizations, the majority (n = 30 440, 90.3%) of children were admitted for nontraumatic causes. Of these children, 15 142 (49.7%) underwent surgery during the hospitalization, with the percentage declining over time (P < .001). When surgical procedures were classified according to likely purpose, the most common were to insert or address hardware or catheters (31%), explore or aid in diagnosis (14%), attempt to rescue patient from mortality (13%), or obtain a biopsy (13%). Specific CCC types were associated with undergoing surgery. Surgery during terminal hospitalization was less likely among Hispanic children (47.8%; P < .001), increasingly less likely as patient age increased, and more so for Black, Asian American, and Hispanic patients compared with white patients (P < .001). CONCLUSIONS: Nearly half of children undergo surgery during their terminal hospitalization, and accordingly, pediatric surgical care is an important aspect of end-of-life care in hospital settings. Differences observed across race and ethnicity categories of patients may reflect different preferences for and access to nonhospital-based palliative, hospice, and end-of-life care.

RESUMO

INTRODUCTION: We sought to evaluate whether the Emergency Surgery Score (ESS) can accurately predict outcomes in elderly patients undergoing emergent laparotomy (EL). METHODS: This is a post-hoc analysis of an EAST multicenter study. Between April 2018 and June 2019, all adult patients undergoing EL in 19 participating hospitals were prospectively enrolled, and ESS was calculated for each patient. Using the c-statistic, the correlation between ESS and mortality, morbidity, and need for ICU admission was assessed in three patient age cohorts (65-74, 75-84, ≥85 years old). RESULTS: 715 patients were included, of which 52% were 65-74, 34% were 75-84, and 14% were ≥85 years old; 51% were female, and 77% were white. ESS strongly correlated with postoperative mortality (c-statistic:0.81). Mortality gradually increased from 0% to 20%-60% at ESS of 2, 10 and 16 points, respectively. ESS predicted mortality, morbidity, and need for ICU best in patients 65-74 years old (c-statistic:0.81, 0.75, 0.83 respectively), but its performance significantly decreased in patients ≥85 years (c-statistic:0.72, 0.64, 0.67 respectively). CONCLUSION: ESS is an accurate predictor of outcome in the elderly EL patient 65-85 years old, but its performance decreases for patients ≥85. Consideration should be given to modify ESS to better predict outcomes in the very elderly patient population.

RESUMO

BACKGROUND: The Emergency Surgery Score (ESS) was recently validated as an accurate mortality risk calculator for emergency general surgery. We sought to prospectively evaluate whether ESS can predict the need for respiratory and/or renal support (RRS) at discharge after emergent laparotomies (EL). METHODS: This is a post hoc analysis of a 19-center prospective observational study. Between April 2018 and June 2019, all adult patients undergoing EL were enrolled. Preoperative, intraoperative, and postoperative variables were systematically collected. In this analysis, patients were excluded if they died during the index hospitalization, were discharged to hospice, or transferred to other hospitals. A composite variable, the need for RRS, was defined as the need for one or more of the following at hospital discharge: tracheostomy, ventilator dependence, or dialysis. Emergency Surgery Score was calculated for all patients, and the correlation between ESS and RRS was examined using the c-statistics method. RESULTS: From a total of 1,649 patients, 1,347 were included. Median age was 60 years, 49.4% were men, and 70.9% were White. The most common diagnoses were hollow viscus organ perforation (28.1%) and small bowel obstruction (24.5%); 87 patients (6.5%) had a need for RRS (4.7% tracheostomy, 2.7% dialysis, and 1.3% ventilator dependence). Emergency Surgery Score predicted the need for RRS in a stepwise fashion; for example, 0.7%, 26.2%, and 85.7% of patients required RRS at an ESS of 2, 12, and 16, respectively. The c-statistics for the need for RRS, the need for tracheostomy, ventilator dependence, or dialysis at discharge were 0.84, 0.82, 0.79, and 0.88, respectively. CONCLUSION: Emergency Surgery Score accurately predicts the need for RRS at discharge in EL patients and could be used for preoperative patient counseling and for quality of care benchmarking. LEVEL OF EVIDENCE: Prognostic and epidemiological, level III.

RESUMO

BACKGROUND: The Emergency Surgery Score (ESS) was recently developed and retrospectively validated as an accurate mortality risk calculator for emergency general surgery. We sought to prospectively validate ESS, specifically in the high-risk nontrauma emergency laparotomy (EL) patient. METHODS: This is an Eastern Association for the Surgery of Trauma multicenter prospective observational study. Between April 2018 and June 2019, 19 centers enrolled all adults (aged >18 years) undergoing EL. Preoperative, intraoperative, and postoperative variables were prospectively and systematically collected. Emergency Surgery Score was calculated for each patient and validated using c-statistic methodology by correlating it with three postoperative outcomes: (1) 30-day mortality, (2) 30-day complications (e.g., respiratory/renal failure, infection), and (3) postoperative intensive care unit (ICU) admission. RESULTS: A total of 1,649 patients were included. The mean age was 60.5 years, 50.3% were female, and 71.4% were white. The mean ESS was 6, and the most common indication for EL was hollow viscus perforation. The 30-day mortality and complication rates were 14.8% and 53.3%; 57.0% of patients required ICU admission. Emergency Surgery Score gradually and accurately predicted 30-day mortality; 3.5%, 50.0%, and 85.7% of patients with ESS of 3, 12, and 17 died after surgery, respectively, with a c-statistic of 0.84. Similarly, ESS gradually and accurately predicted complications; 21.0%, 57.1%, and 88.9% of patients with ESS of 1, 6, and 13 developed postoperative complications, with a c-statistic of 0.74. Emergency Surgery Score also accurately predicted which patients required intensive care unit admission (c-statistic, 0.80). CONCLUSION: This is the first prospective multicenter study to validate ESS as an accurate predictor of outcome in the EL patient. Emergency Surgery Score can prove useful for (1) perioperative patient and family counseling, (2) triaging patients to the intensive care unit, and (3) benchmarking the quality of emergency general surgery care. LEVEL OF EVIDENCE: Prognostic study, level III.

RESUMO

BACKGROUND: In trauma research, accurate estimates of mortality that can be rapidly calculated prior to enrollment are essential to ensure appropriate patient selection and adequate sample size. This study compares the accuracy of the BIG (Base Deficit, International normalized ratio and Glasgow Coma scale) score in predicting mortality in pediatric trauma patients to Pediatric Risk of Mortality III (PRISM III) score, Pediatric Index of Mortality 2 (PIM2) score and Pediatric Logistic Organ Dysfunction (PELOD) score. METHODS: Data were collected from Virtual Pediatric Systems (VPS, LLC) database for children between 2004 and 2015 from 149 PICUs. Logistic regression models were developed to evaluate mortality prediction. The Area under the Curve (AUC) of Receiver Operator Characteristic (ROC) curves were derived from these models and compared between scores. RESULTS: A total of 45,377 trauma patients were analyzed. The BIG score could only be calculated for 152 patients (0.33%). PRISM III, PIM2, and PELOD scores were calculated for 44,360, 45,377 and 14,768 patients respectively. The AUC of the BIG score was 0.94 compared to 0.96, 0.97 and 0.93 for the PRISM III, PIM2, and PELOD respectively. CONCLUSIONS: The BIG score is accurate in predicting mortality in pediatric trauma patients. LEVEL OF EVIDENCE: Level I prognosis.
