RESUMEN
BACKGROUND: Cardiogenic shock (CS) remains a leading cause of mortality despite advancements in mechanical circulatory support and other management strategies. In particular, venoarterial extracorporeal membrane oxygenation (ECMO) requires expertise in cardiac surgery, cardiology, and critical care. The benefits of such expertise may extend beyond ECMO patients. METHODS: Adult (≥18 years) hospitalizations with a primary diagnosis of CS, not undergoing ECMO, cardiac operations, durable LVAD, or transplantation, were abstracted from the 2016-2020 Nationwide Readmissions Database. Multivariable regression models were developed to assess the association of cardiac surgical and ECMO institutional caseload with clinical and financial outcomes. RESULTS: Of an estimated 70,339 patients with CS identified for study, 33,643 (47.8%) were treated at a high-volume hospital for ECMO (HVH-ECMO). HVH-ECMO was associated with decreased odds of in-hospital mortality (AOR 0.85, CI 0.75 - 0.95), respiratory complications (AOR 0.86, CI 0.79 - 0.94), and non-home discharge (AOR 0.86, CI 0.79 - 0.94). However, HVH-ECMO was associated with greater LOS by 1.7 days (CI 1.3 - 2.1) and inpatient costs by $9,170 (CI $6,490 - $12,060). While ECMO volume was inversely associated with the predicted risk of in-hospital mortality, institutional volume of cardiac operations was not significantly associated with mortality. CONCLUSIONS: Our findings suggest improved outcomes for CS patients treated at a HVH-ECMO. Multidisciplinary care pathways, including those among surgery, cardiology, and critical care, may influence CS management. Further studies are needed to characterize long-term outcomes of regionalization and ensure equitable access for all populations.
RESUMEN
OBJECTIVE: Given the nonelective nature of most trauma admissions, patients who experience trauma are at a particular risk of discharge against medical advice. Despite the risk of unplanned readmission and financial burden on the health care system, discharge against medical advice among hospitalized patients continues to rise. The present study aimed to assess evolving trends and outcomes associated in patients with discharge against medical advice among patients hospitalized for traumatic injury. METHODS: The 2016-2020 Nationwide Readmissions Database was queried to identify all hospitalizations for traumatic injuries. The patient cohort was stratified into those who had discharge against medical advice and those who did not. Temporal trends of discharge against medical advice and associated costs over time were evaluated using nonparametric tests. Multivariable regression models were developed to assess factors associated with discharge against medical advice. Associations of discharge against medical advice with length of stay, hospitalization costs, and unplanned 30-day readmission were subsequently evaluated. RESULTS: Of an estimated 4,969,717 patients, 65,354 (1.3%) had discharge against medical advice after hospitalization for traumatic injury. Over the study period, the incidence of discharge against medical advice increased (nptrend <0.001). After risk adjustment, older age (adjusted odds ratio, 0.98/per year; 95% confidence interval, 0.97-0.98), female sex (adjusted odds ratio, 0.65; 95% confidence interval, 0.64-0.67), and management at high-volume trauma center (adjusted odds ratio, 0.71; 95% confidence interval, 0.69-0.74) were associated with lower odds of discharge against medical advice. Compared with others, discharge against medical advice was associated with decrements in length of stay by 1.3 days (95% confidence interval, 1.1-1.5 days) and index hospitalization costs by $2,200 (5% confidence interval, $1,600-2,900), while having a greater risk of unplanned 30-day readmission (adjusted odds ratio, 2.21; 95% confidence interval, 2.06-2.36). CONCLUSION: The incidence of discharge against medical advice and its associated cost burden have increased in recent years. Community-level interventions and institutional efforts to mitigate discharge against medical advice may improve the quality of care and resource allocation for patients with traumatic injuries.
RESUMEN
Background: Failure to rescue (FTR) is increasingly recognized as a quality metric but remains understudied in emergency general surgery (EGS). We sought to identify patient and operative factors associated with FTR to better inform standardized metrics to mitigate this potentially preventable event. Methods: All adult (≥18â¯years) non-elective hospitalizations for large bowel resection, small bowel resection, repair of perforated ulcer, laparotomy and lysis of adhesions were identified in the 2016-2020 National Readmissions Database. Patients undergoing trauma-related operations or procedures ≤2â¯days of admission were excluded. FTR was defined as in-hospital death following acute kidney injury requiring dialysis (AKI), myocardial infarction, pneumonia, respiratory failure, sepsis, stroke, or thromboembolism. Multilevel mixed-effect models were developed to assess factors linked with FTR. Results: Among 826,548 EGS operations satisfying inclusion criteria, 298,062 (36.1â¯%) developed at least one MAE. Of those experiencing MAE, 43,477 (14.6â¯%) ultimately did not survive to discharge (FTR). Following adjustment for fixed hospital level effects, only 3.5â¯% of the variance in FTR was attributable to center-level differences. Relative to private insurance and the highest income quartile, Medicaid insurance (AOR 1.33; 95%CI, 1.23-1.43) and the lowest income quartile (AOR 1.22; 95%CI, 1.17-1.29) were linked with increased odds of FTR.A subset analysis stratified complication-specific rates of FTR by insurance status. Relative to private insurance, Medicaid coverage and uninsured status were linked with greater odds of FTR following perioperative sepsis, pneumonia, and AKI. Conclusion: Our findings underscore the need for increased screening and vigilance following perioperative complications to mitigate disparities in patient outcomes following high-risk EGS.
RESUMEN
Background: Obesity is a known risk factor for cholecystitis and is associated with technical complications during laparoscopic procedures. The present study seeks to assess the association between obesity class and conversion to open (CTO) during laparoscopic cholecystectomy (LC). Methods: Adult acute cholecystitis patients with obesity undergoing non-elective LC were identified in the 2017-2020 Nationwide Readmissions Database. Patients were stratified by obesity class; class 1 (Body Mass Index [BMI] = 30.0-34.9), class 2 (BMI = 35.0-39.9), and class 3 (BMI ≥ 40.0). Multivariable regression models were developed to assess factors associated with CTO and its association with perioperative complications and resource utilization. Results: Of 89,476 patients undergoing LC, 40.6 % had BMI ≥ 40.0. Before adjustment, class 3 obesity was associated with increased rates of CTO compared to class 1-2 (4.6 vs 3.8 %; p < 0.001). Following adjustment, class 3 remained associated with an increased likelihood of CTO (Adjusted Odds Ratio [AOR] 1.45, 95 % Confidence Interval [CI] 1.31-1.61; ref.: class 1-2). Patients undergoing CTO had increased risk of blood transfusion (AOR 3.27, 95 % CI 2.54-4.22) and respiratory complications (AOR 1.36, 95 % CI 1.01-1.85). Finally, CTO was associated with incremental increases in hospitalization costs (ß + $719, 95 % CI 538-899) and length of stay (LOS; ß +2.20 days, 95 % CI 2.05-2.34). Conclusions: Class 3 obesity is a significant risk factor for CTO. Moreover, CTO is associated with increased hospitalization costs and LOS. As the prevalence of obesity grows, improved understanding of operative risk by approach is required to optimize clinical outcomes. Our findings are relevant to shared decision-making and informed consent.
RESUMEN
Background: Black race has been associated with increased resource utilization after operation for small bowel obstruction (SBO). While prior literature has similarly demonstrated differences between urban and rural institutions, limited work has defined the impact of rurality on resource utilization by race. Methods: The 2016-2020 National Inpatient Sample was used to identify adults undergoing adhesiolysis after non-elective admission for SBO. The primary endpoint was hospitalization costs. Additional outcomes included surgical delay (≥ hospital day 3), length of stay (LOS), and nonhome discharge. Regression models were developed to identify the impact of Black race and rurality on the outcomes of interest with an interaction term to examine the incremental association of Black race on rurality. Results: Of an estimated 132,390 patients, 11.4 % were treated at an annual average of 377 rural hospitals (18.5 % of institutions). After adjustment, rural hospitals had higher costs (ß + $4900, 95 % Confidence Interval [CI] [4200, 5700]), compared to others. However, rurality was associated with reduced odds of surgical delay (Adjusted Odds Ratio [AOR] 0. 76, CI[0.69, 0.85]), decreased LOS (ß -1.66 days, CI[-1.99, -1.36]), and nonhome discharge (AOR 0.78, CI[0.70, 0.87]). While White patients experienced significant cost reductions at urban centers ($26,100 [25,800-26,300] vs $31,000 [30,300-31,700]), this was not noted for Black patients ($30,100 [29,400-30,700] vs $30,800 [29,300-32,400]). Conclusions: We found that Black patients do not benefit from the same cost protection afforded by urban settings as White patients after operative SBO admission. Future work should focus on setting-specific interventions to address drivers of disparities within each community.
RESUMEN
BACKGROUND: With the aging population in the United States, the incidence of abdominal aortic aneurysms is shifting to older ages. Given changing demographic characteristics and increasing health care expenditures, the present study evaluated the degree of center-level variation in the cost of elective abdominal aortic aneurysm repair. METHODS: We identified all adult (≥18 years) hospitalizations for elective repair of nonruptured abdominal aortic aneurysms in the 2017 to 2020 Nationwide Readmissions Database. Hierarchical mixed-effects models were used to rank hospitals based on risk-adjusted costs. The interclass coefficient was used to calculate the amount of variation attributable to hospital-level characteristics. High-cost hospitals were classified as centers in the top decile of costs. The association of high-cost hospitals status with outcomes of interest was examined. RESULTS: An estimated 62,626 patients underwent abdominal aortic aneurysm repair, and 5,011 (8.0%) were managed at high-cost hospitals. Compared with non-high-cost hospitals, high-cost hospitals were more commonly large (52.6% vs 48.3%) metropolitan (78.3% vs 66.9%) teaching centers (all P < .001). The interclass coefficient found that 28% of the observed variation in cost is attributable to hospital factors. After adjustment, high-cost hospitals were associated with increased odds of gastrointestinal (adjusted odds ratio = 1.42; 95% CI, 1.05-1.90) and infectious (adjusted odds ratio = 1.35; 95% CI, 1.14-1.59) complications. Finally, the Elixhauser index (ß = +$2,700/unit; 95% CI, $2,500-$3,000) and open repair (ß = +$4,100; 95% CI, $3,100-$5,200) were associated with increased costs. CONCLUSION: We observed significant variation in cost attributable to center-level differences. Our findings have implications for reimbursement paradigms and the establishment of quality and cost benchmarks in the elective repair of abdominal aortic aneurysm.
RESUMEN
Introduction: Despite considerable national attention, racial disparities in surgical outcomes persist. We sought to consider whether race-based inequities in outcomes following major elective surgery have improved in the contemporary era. Methods: All adult hospitalization records for elective coronary artery bypass grafting, abdominal aortic aneurysm repair, colectomy, and hip replacement were tabulated from the 2016-2020 National Inpatient Sample. Patients were stratified by Black or White race. To consider the evolution in outcomes, we included an interaction term between race and year. We designated centers in the top quartile of annual procedural volume as high-volume hospitals (HVH). Results: Of â¼2,838,485 patients, 245,405 (8.6%) were of Black race. Following risk-adjustment, Black race was linked with similar odds of in-hospital mortality, but increased likelihood of major complications (Adjusted Odds Ratio [AOR] 1.41, 95%Confidence Interval [CI] 1.36-1.47). From 2016-2020, overall risk-adjusted rates of major complications declined (patients of White race: 9.2% to 8.4%; patients of Black race 11.8% to 10.8%, both P < .001). Yet, the delta in risk of adverse outcomes between patients of White and Black race did not significantly change. Of the cohort, 158,060 (8.4%) were treated at HVH. Following adjustment, Black race remained associated with greater odds of morbidity (AOR 1.37, CI 1.23-1.52; Ref:White). The race-based difference in risk of complications at HVH did not significantly change from 2016 to 2020. Conclusion: While overall rates of complications following major elective procedures declined from 2016 to 2020, patients of Black race faced persistently greater risk of adverse outcomes. Novel interventions are needed to address persistent racial disparities and ensure acceptable outcomes for all patients.
RESUMEN
BACKGROUND: Recent studies have demonstrated a positive volume-outcome relationship in emergency general surgery. Some have advocated for the sub-specialization of emergency general surgery independent from trauma. We hypothesized inferior clinical outcomes of emergency general surgery with increasing center-level operative trauma volume, potentially attributable to overall hospital quality. METHODS: Adults (≥18 years) undergoing complex emergency general surgery operations (large and small bowel resection, repair of perforated peptic ulcer, lysis of adhesions, laparotomy) were identified in the 2016 to 2020 Nationwide Readmissions Database. Multivariable risk-adjusted models were developed to evaluate the association of treatment at a high-volume trauma center (reference: low-volume trauma center) with clinical and financial outcomes after emergency general surgery. To evaluate hospital quality, mortality among adult hospitalizations for acute myocardial infarction was assessed by hospital trauma volume. RESULTS: Of an estimated 785,793 patients undergoing a complex emergency general surgery operation, 223,116 (28.4%) were treated at a high-volume trauma center. Treatment at a high-volume trauma center was linked to 1.19 odds of in-hospital mortality (95% confidence interval 1.12-1.27). Although emergency general surgery volume was associated with decreasing predicted risk of mortality, increasing trauma volume was linked to an incremental rise in the odds of mortality after emergency general surgery. Secondary analysis revealed increased mortality for admissions for acute myocardial infarction with greater trauma volume. CONCLUSION: We note increased mortality for emergency general surgery and acute myocardial infarction in patients receiving treatment at high-volume trauma centers, signifying underlying structural factors to broadly affect quality. Thus, decoupling trauma and emergency general surgery services may not meaningfully improve outcomes for emergency general surgery patients. Our findings have implications for the evolving specialty of emergency general surgery, especially for the safety and continued growth of the acute care surgery model.

BACKGROUND: Pediatric traumatic injury is associated with long-term morbidity as well as substantial economic burden. Prior work has labeled the catastrophic out-of-pocket medical expenses borne by patients as financial toxicity. We hypothesized uninsured rural patients to be vulnerable to exorbitant costs and thus at greatest risk of financial toxicity. METHODS: Pediatric patients (<18 years) experiencing traumatic injury were identified in the 2016-2019 National Inpatient Sample. Patients were considered to be at risk of financial toxicity if their hospitalization cost exceeded 40% of post-subsistence income. Individual family income was computed using a gamma distribution probability density function with parameters derived from publicly available US Census Bureau data, in accordance with prior work. A multivariable logistic regression was developed to assess factors associated with risk of financial toxicity. RESULTS: Of an estimated 225,265 children identified for study, 34,395 (15.3%) were Rural. Rural patients were more likely to experience risk of financial toxicity (29.1 vs 22.2%, P < .001) compared to Urban patients. After adjustment, rurality (reference: urban status; adjusted odds ratio 1.45, 95% confidence interval 1.36-1.55) and uninsured status (reference: private; adjusted odds ratio 1.85, 95% confidence interval 1.67-2.05) remained linked to increased odds of risk of financial toxicity. Specifically among those with private insurance, Rural patients experienced markedly higher predicted risk of financial toxicity, relative to Urban. CONCLUSION: Our findings suggest a complex interplay between rural status and insurance type in the prediction of risk of financial toxicity after pediatric trauma. To target policy interventions, future studies should characterize the patients and communities at greatest risk of financial devastation among rural pediatric trauma patients.

BACKGROUND: Multi-arterial coronary bypass grafting with the left internal mammary artery as a conduit has been shown to offer superior long-term survival compared to single-arterial coronary bypass grafting. Nevertheless, the selection of a secondary conduit between the right internal mammary artery and the radial artery remains controversial. Using a national cohort, we examined the relationships between the right internal mammary artery and the radial artery with acute clinical and financial outcomes. METHODS: Adults undergoing on-pump multivessel coronary bypass grafting with left internal mammary artery as the first arterial conduit were identified in the 2016 to 2020 Nationwide Readmissions Database. Patients receiving either the right internal mammary artery or the radial artery, but not both, were included in the analysis. Multivariable regression models were fitted to examine the association between the conduits and in-hospital mortality, as well as additional secondary outcomes. RESULTS: Of an estimated 49,798 patients undergoing multi-arterial coronary bypass grafting, 29,729 (59.7%) comprised the radial artery cohort. During the study period, the proportion of multi-arterial coronary bypass grafting utilizing the radial artery increased from 51.3% to 65.2% (nptrend <0.001). Following adjustment, the radial artery was associated with reduced odds of in-hospital mortality (adjusted odds ratio 0.44), prolonged mechanical ventilation (adjusted odds ratio 0.78), infectious complications (adjusted odds ratio 0.69), and 30-day nonelective readmission (adjusted odds ratio 0.77, all P < .05). CONCLUSION: Despite no definite endorsement from surgical societies, the radial artery is increasingly utilized as a secondary conduit in multi-arterial coronary bypass grafting. Compared to the right internal mammary artery, the radial artery was associated with lower odds of in-hospital mortality, complications, and reduced healthcare expenditures. These results suggest that whenever feasible, the radial artery should be the favored conduit over the right internal mammary artery. Nevertheless, future studies examining long-term outcomes associated with these vessels remain necessary.

Background: Alcohol withdrawal syndrome (AWS) presents with a complex spectrum of clinical manifestations that complicate postoperative management. In trauma setting, subjective screening for AWS remains challenging due to the criticality of injury in these patients. We thus identified several patient characteristics and perioperative outcomes associated AWS development. Methods: The 2016-2020 National Inpatient Sample was queried to identify all non-elective adult (≥18 years) hospitalizations for blunt or penetrating trauma undergoing operative management with a diagnosis of AWS. Patients with traumatic brain injury or with a hospital duration of stay <2 days were excluded. Outcomes of interest included in-hospital mortality, perioperative complications, hospitalization costs, length of stay (LOS) and non-home discharge. Results: Of an estimated 2,965,079 operative trauma hospitalizations included for analysis, 36,415 (1.23 %) developed AWS following admission. The AWS cohort demonstrated increased odds of mortality (Adjusted Odds Ratio [AOR] 1.46, 95 % Confidence Interval [95 % CI] 1.23-1.73), along with infectious (AOR 1.73, 95 % CI 1.58-1.88), cardiac (AOR 1.24, 95 % CI 1.06-1.46), and respiratory (AOR 1.96, 95 % CI 1.81-2.11) complications. AWS was associated with prolonged LOS, (ß: 3.3 days, 95 % CI: 3.0 to 3.5), greater cost (ß: +$8900, 95 % CI $7900-9800) and incremental odds of nonhome discharge (AOR 1.43, 95 % CI 1.34-1.53). Furthermore, male sex, Medicaid insurance status, head injury and thoracic operation were linked with greater odds of development of AWS. Conclusion: In the present study, AWS development was associated with increased odds of in-hospital mortality, perioperative complications, and resource burden. The identification of patient and operative characteristics linked with AWS may improve screening protocols in trauma care.
RESUMEN
BACKGROUND: Transcatheter mitral valve replacement (TMVR) has garnered interest as a viable alternative to the traditional surgical mitral valve replacement (SMVR) for high-risk patients requiring redo operations. This study aims to evaluate the association of TMVR with selected clinical and financial outcomes. METHODS: Adults undergoing isolated redo mitral valve replacement were identified in the 2016-2020 Nationwide Readmissions Database and categorized into TMVR or SMVR cohorts. Various regression models were developed to assess the association between TMVR and in-hospital mortality, as well as additional secondary outcomes. Transseptal and transapical catheter-based approaches were also compared in relation to study endpoints. RESULTS: Of an estimated 7,725 patients, 2,941 (38.1%) underwent TMVR. During the study period, the proportion of TMVR for redo operations increased from 17.8% to 46.7% (nptrend<0.001). Following adjustment, TMVR was associated with similar odds of in-hospital mortality (AOR 0.82, p = 0.48), but lower odds of stroke (AOR 0.44, p = 0.001), prolonged ventilation (AOR 0.43, p<0.001), acute kidney injury (AOR 0.61, p<0.001), and reoperation (AOR 0.29, p = 0.02). TMVR was additionally correlated with shorter postoperative length of stay (pLOS; ß -0.98, p<0.001) and reduced costs (ß -$10,100, p = 0.002). Additional analysis demonstrated that the transseptal approach had lower adjusted mortality (AOR 0.44, p = 0.02), shorter adjusted pLOS (ß -0.43, p<0.001), but higher overall costs (ß $5,200, p = 0.04), compared to transapical. CONCLUSIONS: In this retrospective cohort study, we noted TMVR to yield similar odds of in-hospital mortality as SMVR, but fewer complications and reduced healthcare expenditures. Moreover, transseptal approaches were associated with lower adjusted mortality, shorter pLOS, but higher cost, relative to the transapical. Our findings suggest that TMVR represent a cost-effective and safe treatment modality for patients requiring redo mitral valve procedures. Nevertheless, future studies examining long-term outcomes associated with SMVR and TMVR in redo mitral valve operations, are needed.

INTRODUCTION: Immediate breast reconstruction (IBR) following mastectomy has been shown to improve quality of life and partially mitigate the adverse psychological impacts associated with the procedure. The present study examined hospital-based and patient-level disparities in utilization and outcomes of IBR following mastectomy. METHODS: All female adult hospitalizations with a diagnosis of breast cancer undergoing mastectomy were identified in the 2016 to 2020 National Inpatient Sample. Safety-net hospitals (SNH) were defined as those in the top quartile of all Medicaid or self-pay admissions. Patients who underwent mastectomy at SNH comprised the SNH cohort (others: Non-SNH). Multivariable models were developed to examine the impact of SNH status and patient factors on rates of IBR. RESULTS: Of an estimated 127,740 hospitalizations, 28,330 (22.2%) were treated at SNH. The proportion of patients receiving IBR increased from 46.7% in 2016 to 51.7% in 2020 (nptrend<.001). Compared to others, SNH were younger (57.9 ± 13.5 vs 58.3 ± 13.5 years) and less commonly White (45.6 vs 69.9%) (all P < .001). Additionally, SNH were more likely to receive unilateral mastectomy (67.1 vs 55.2%) but less frequently underwent IBR (37.7 vs 51.5%) (all P < .001). After adjustment, Black and Asian race, SNH, and bilateral mastectomy were associated with decreased odds of IBR. Increasing IBR hospital volume did not eliminate the observed racial disparity at non-SNH or SNH. CONCLUSION: There are disparities in rates of IBR following mastectomy attributable to SNH status. Future work is needed to ensure all patients have access to reconstructive care irrespective of payer status or the hospital at which they receive care.
RESUMEN
BACKGROUND: Extracorporeal membrane oxygenation (ECMO) has emerged as a life-sustaining measure for individuals with end-stage cardiopulmonary derangements. An estimated one-third of patients must be transferred to a specialized center to receive this intervention. Therefore, the present study sought to characterize the impact of interhospital transfer (IHT) status on outcomes following ECMO. METHODS: The 2016-2020 National Inpatient Sample was queried to identify all adult (≥18 years) hospitalizations for ECMO. Patients were stratified based on transfer status from another acute care hospital. Multivariable regression models were developed to assess the association between transfer status and outcomes of interest. Patient and operative factors associated with IHT were identified using regression. RESULTS: Of an estimated 61,180 hospitalizations entailing ECMO, 21,410 (35.0%) were transfers. Annual transfer volume doubled over the study period, from 2915 to 5945 (nptrend < .001). The predicted morality risk of non-transfers decreased between 2016 and 2020 but remained similar in transferred patients. Following adjustment, transfer was associated with increased odds of in-hospital mortality, complications, duration of stay, and hospitalization costs. Patients experiencing transfer were less likely to be of black race and private insurance status. CONCLUSION: Despite increasing transfer volume and utilization of ECMO, IHT was associated with significant mortality and hospital complication risks. Further work to reduce adverse outcomes, resource burden, and socioeconomic differences within IHT may improve accessibility to this life-saving modality.
RESUMEN
BACKGROUND: Appendectomy remains a common pediatric surgical procedure with an estimated 80,000 operations performed each year. While prior work has reported the existence of racial disparities in postoperative outcomes, we sought to characterize potential income-based inequalities using a national cohort. METHODS: All non-elective pediatric (<18 years) hospitalizations for appendectomy were tabulated in the 2016-2020 National Inpatient Sample. Only those in the highest (HI) and lowest income (LI) quartiles were considered for analysis. Multivariable regression models were developed to assess the independent association of income and postoperative major adverse events (MAE). RESULTS: Of an estimated 87,830 patients, 36,845 (42.0%) were HI and 50,985 (58.0%) were LI. On average, LI patients were younger (11 [7-14] vs 12 [8-15] years, P < .001), more frequently insured by Medicaid (70.7 vs 27.3%, P < .05), and more commonly of Hispanic ethnicity (50.8 vs 23.4%, P < .001). Following risk adjustment, the LI cohort was associated with greater odds of MAE (adjusted odds ratio [AOR] 1.30 95% confidence interval [CI] 1.06-1.64). Specifically, low-income status was linked with increased odds of infectious (AOR 1.65, 95% CI 1.12-2.42) and respiratory (AOR 1.67, 95% CI 1.06-2.62) complications. Further, LI was associated with a $1670 decrement in costs ([2220-$1120]) and a +.32-day increase in duration of stay (95% CI [.21-.44]). CONCLUSION: Pediatric patients of the lowest income quartile faced increased risk of major adverse events following appendectomy compared to those of highest income. Novel risk stratification methods and standardized care pathways are needed to ameliorate socioeconomic disparities in postoperative outcomes.
RESUMEN
BACKGROUND: Patients undergoing emergency general surgery (EGS) often require complex management and transfer to higher acuity facilities, especially given increasing national efforts aimed at centralizing care. We sought to characterize factors and evaluate outcomes associated with interhospital transfer using a contemporary national cohort. METHODS: All adult hospitalizations for EGS (appendectomy, cholecystectomy, laparotomy, lysis of adhesions, small/large bowel resection, and perforated ulcer repair) ≤2 days of admission were identified in the 2016-2020 National Inpatient Sample. Patients initially admitted to a different institution and transferred to the operating hospital comprised the Transfer cohort (others: Non-Transfer). Multivariable models were developed to consider the association of Transfer with outcomes of interest. RESULTS: Of â¼1 653 169 patients, 107 945 (6.5%) were considered the Transfer cohort. The proportion of patients experiencing interhospital transfer increased from 5.2% to 7.7% (2016-2020, P < .001). On average, Transfer was older, more commonly of White race, and of a higher Elixhauser comorbidity index. After adjustment, increasing age, living in a rural area, receiving care in the Midwest, and decreasing income quartile were associated with greater odds of interhospital transfer. Following risk adjustment, Transfer remained linked with increased odds of in-hospital mortality (AOR 1.64, CI 1.49-1.80), as well as any perioperative complication (AOR 1.33, CI 1.27-1.38; Reference: Non-Transfer). Additionally, Transfer was associated with significantly longer duration of hospitalization (ß + 1.04 days, CI + .91-1.17) and greater costs (ß+$3,490, CI + 2840-4140). DISCUSSION: While incidence of interhospital transfer for EGS is increasing, transfer patients face greater morbidity and resource utilization. Novel interventions are needed to optimize patient selection and improve post-transfer outcomes.
RESUMEN
Background: Despite increasing utilization and survival benefit over the last decade, extracorporeal membrane oxygenation (ECMO) remains resource-intensive with significant complications and rehospitalization risk. We thus utilized machine learning (ML) to develop prediction models for 90-day nonelective readmission following ECMO. Methods: All adult patients receiving ECMO who survived index hospitalization were tabulated from the 2016-2020 Nationwide Readmissions Database. Extreme Gradient Boosting (XGBoost) models were developed to identify features associated with readmission following ECMO. Area under the receiver operating characteristic (AUROC), mean Average Precision (mAP), and the Brier score were calculated to estimate model performance relative to logistic regression (LR). Shapley Additive Explanation summary (SHAP) plots evaluated the relative impact of each factor on the model. An additional sensitivity analysis solely included patient comorbidities and indication for ECMO as potential model covariates. Results: Of â¼22,947 patients, 4495 (19.6 %) were readmitted nonelectively within 90 days. The XGBoost model exhibited superior discrimination (AUROC 0.64 vs 0.49), classification accuracy (mAP 0.30 vs 0.20) and calibration (Brier score 0.154 vs 0.165, all P < 0.001) in predicting readmission compared to LR. SHAP plots identified duration of index hospitalization, undergoing heart/lung transplantation, and Medicare insurance to be associated with increased odds of readmission. Upon sub-analysis, XGBoost demonstrated superior disclination compared to LR (AUROC 0.61 vs 0.60, P < 0.05). Chronic liver disease and frailty were linked with increased odds of nonelective readmission. Conclusions: ML outperformed LR in predicting readmission following ECMO. Future work is needed to identify other factors linked with readmission and further optimize post-ECMO care among this cohort.
RESUMEN
BACKGROUND: Peripheral vascular trauma is a major contributing factor to long-term disability and mortality among patients with traumatic injuries. However, an analysis focusing on individuals at a high risk of experiencing limb loss due to rural and urban peripheral vascular trauma is lacking. METHOD: This was a retrospective analysis of the 2016 to 2020 Nationwide Readmissions Database. Patients (≥18 years) undergoing open or endovascular procedures after admission for peripheral vascular trauma were identified using the 2016 to 2020 Nationwide Readmissions Database. Patients from rural regions were considered Rural, whereas the remainder comprised Urban. The primary outcome of the study was primary amputation. Multivariable regression models were developed to evaluate rurality with outcomes of interest. RESULTS: Of 29,083 patients, 4,486 (15.6%) were Rural. Rural were older (41 [28-59] vs 37 [27-54] years, P < .001), with a similar distribution of female sex (23.0 vs 21.3%, P = .09) and transfers from other facilities (2.8 vs 2.5%, P = .34). After adjustment, Rural status was not associated with the odds of mortality (P = .82), with urban as reference. Rural status was, however, associated with greater odds of limb amputation (adjusted odds ratio 1.85, 95% confidence interval 1.47-2.32) and reduced index hospitalization cost by $7,100 (95% confidence interval $3,500-10,800). Additionally, compared to patients from urban locations, rurality was associated with similar odds of non-home discharge and 30-day readmission. Over the study period, the marginal effect of rurality on the risk-adjusted rates of amputation significantly increased (P < .001). CONCLUSION: Patients who undergo peripheral vascular trauma management in rural areas appear to increasingly exhibit a higher likelihood of amputation, with lower incremental costs and a lower risk of 30-day readmission. These findings underscore disparities in access to optimal trauma vascular care as well as limited resources in rural regions.

BACKGROUND: Contralateral prophylactic mastectomy (CPM) remains a personal decision, influenced by psychosocial factors, including cosmesis and peace of mind. Although use of CPM is disproportionately low among Black patients, the degree to which these disparities are driven by patient- vs hospital-level factors remains unknown. STUDY DESIGN: Patients undergoing mastectomy for nonmetastatic ductal or lobular breast cancer were tabulated using the National Cancer Database from 2004 to 2020. The primary endpoint was receipt of CPM. Multivariable logistic regression models were constructed with interaction terms between Black-serving hospital (BSH) status and patient race to evaluate associations with CPM. Cox proportional hazard models were used to evaluate long-term survival. RESULTS: Of 597,845 women studied, 70,911 (11.9%) were Black. After multivariable adjustment, Black race (adjusted odds ratio 0.65, 95% CI 0.64 to 0.67) and treatment at BSH (adjusted odds ratio 0.84, 95% CI 0.83 to 0.85) were independently linked to lower odds of CPM. Although predicted probability of CPM was universally lower at higher BSH, Black patients faced a steeper reduction compared with White patients. Receipt of CPM was linked to improved survival (hazard ratio [HR] 0.84, 95% CI 0.83 to 0.86), whereas Black race was associated with a greater HR of 10-year mortality (HR 1.14, 95% CI 1.12 to 1.17). CONCLUSIONS: Hospitals serving a greater proportion of Black patients are less likely to use CPM, suggestive of disparities in access to CPM at the institutional level. Further research and education are needed to characterize surgeon-specific and institutional practices in patient counseling and shared decision-making that shape disparities in access to CPM.

Background: With the growing opioid epidemic across the US, in-hospital utilization of opioids has garnered increasing attention. Using a national cohort, this study sought to characterize trends, outcomes, and factors associated with in-hospital opioid overdose (OD) following major elective operations. Methods: We identified all adult (≥18 years) hospitalizations entailing select elective procedures in the 2016-2020 National Inpatient Sample. Patients who experienced in-hospital opioid overdose were characterized as OD (others: Non-OD). The primary outcome of interest was in-hospital OD. Multivariable logistic and linear regression models were developed to evaluate the association between in-hospital OD and mortality, length of stay (LOS), hospitalization costs, and non-home discharge. Results: Of an estimated 11,096,064 hospitalizations meeting study criteria, 5375 (0.05 %) experienced a perioperative OD. Compared to others, OD were older (66 [57-73] vs 64 [54-72] years, p < 0.001), more commonly female (66.3 vs 56.7 %, p < 0.001), and in the lowest income quartile (26.4 vs 23.2 %, p < 0.001). After adjustment, female sex (Adjusted Odds Ratio [AOR] 1.68, 95 % Confidence Interval [CI] 1.47-1.91, p < 0.001), White race (AOR 1.19, CI 1.01-1.42, p = 0.04), and history of substance use disorder (AOR 2.51, CI 1.87-3.37, p < 0.001) were associated with greater likelihood of OD. Finally, OD was associated with increased LOS (ß +1.91 days, CI [1.60-2.21], p < 0.001), hospitalization costs (ß +$7500, CI [5900-9100], p < 0.001), and greater odds of non-home discharge (AOR 2.00, CI 1.61-2.48, p < 0.001). Conclusion: Perioperative OD remains a rare but costly complication after elective surgery. While pain control remains a priority postoperatively, protocols and recovery pathways must be re-examined to ensure patient safety.
