Defining the Cross-Volume Effect of Extracorporeal Life Support on Outcomes of Cardiogenic Shock.

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.

Discharge against medical advice in trauma patients: Trends, risk factors, and implications for health care management strategies.

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.

Association of severe obesity with risk of conversion to open in laparoscopic cholecystectomy for acute cholecystitis.

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.

Hospital-level variation in costs of elective nonruptured abdominal aortic aneurysm repair.

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.

Impact of Safety-Net Hospital Status on Immediate Reconstruction Following Mastectomy: A Contemporary National Analysis.

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.

Mortality and resource utilization in surgical versus transcatheter repeat mitral valve replacement: A national analysis.

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.

Heart Transplantation After Donation After Circulatory Death: Early United States Experience.

BACKGROUND: Given the renewed interest in heart transplantation after donation after circulatory death (DCD), a contemporary analysis of trends and longer-term survival is warranted. METHODS: Adult heart transplant recipients (December 2019-September 2023) were identified in the Organ Procurement and Transplantation Network. Recipients were stratified as donation after brain death (DBD) or DCD. DCD procurements were further classified as direct procurement and perfusion (DCD-DPP) or normothermic regional perfusion (DCD-NRP), based on the declaration of death to cross-clamp interval (≥40 minutes DCD-NRP). The main outcome was posttransplant survival at 1 and 3 years. RESULTS: Of 11,625 transplantations, 792 (7%) involved DCD allografts (249 DCD-NRP, 543 DCD-DPP). The proportion of transplants involving DCD allografts significantly increased from 2% (December 2019) to 11% (January-September 2023, P < .001). Upon adjusted analysis, 1-year posttransplant survival was similar for DBD vs DCD-DPP (hazard ratio [HR], 1.00; 95% CI, 0.66-1.66) or DCD-NRP (HR, 0.92; 95% CI, 0.49-1.72). This remained true at 3 years for DCD-DPP (HR, 1.07; 95% CI, 0.77-1.48) and DCD-NRP (HR, 1.04; 95% CI, 0.62-1.73). Incidence of postoperative stroke, dialysis, acute graft rejection, and primary graft dysfunction were similar across groups. Across various strata of recipient risk and center volume, survival was equivalent between the DBD and DCD cohorts. CONCLUSIONS: Rates of DCD heart transplantation continue to rise. Across various recipient risk and center volume categories, DCD and DBD recipients show comparable posttransplant survival up to 3 years. These findings encourage broader use of such donors in attempts to expand the organ pool.

A National Analysis of Alcohol Withdrawal Syndrome in Patients with Operative Trauma.

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.

Persistent Racial Disparities in Morbidity Following Major Elective Operations.

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 ∼2,838,485 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.

Demystifying the association of center-level operative trauma volume and outcomes of emergency general surgery.

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.

Association of uninsured status and rurality with risk of financial toxicity after pediatric trauma.

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.

Trends and associated outcomes of fat embolism after trauma surgery.

BACKGROUND: Fat embolism is a life-threatening complication often occurring in patients with traumatic injuries. However, temporal trends and perioperative outcomes of fat embolism remain understudied. Using a nationally representative cohort, we aimed to characterize temporal trends of fat embolism and its associated resource utilization in operatively managed trauma patients. METHODS: All patients (≥18 years) undergoing any major operations after traumatic injuries were tabulated using the 2005 to 2020 National Inpatient Sample. Patients were stratified into those with fat embolism and those without. Multivariable logistic and linear regressions were developed to assess the association between fat embolism and outcomes of interest. RESULTS: Of an estimated 10,600,000 hospitalizations, 7,479 (0.07%) patients had fat embolism. Compared to the non-fat embolism cohort, the fat embolism cohort was younger (55 [26-79] vs 69 [49-82] years, standard mean difference = 0.46) and more likely to receive treatment at a high-volume trauma center (42.9 vs 33.7%, standard mean difference = 0.19). Over the study period, there was an increase in annual mortality and hospitalization costs among the fat embolism group (nptrend <0.001). After risk adjustment, fat embolism was associated with greater odds of mortality (adjusted odds ratio: 2.65, 95% confidence interval: 2.24-3.14) compared to others. Additionally, fat embolism was associated with increased odds of cerebrovascular, infectious, and renal complications. CONCLUSION: Among all operatively managed trauma patients, those who developed fat embolism had increased mortality, rates of complications, length of stay, and costs. Optimization of early and accurate identification of fat embolism is warranted to mitigate complications and improve resource allocation among trauma patients.

Association of substance-use disorder with outcomes of major elective abdominal operations: A contemporary national analysis.

Background: Affecting >20million people in the U.S., including 4 % of all hospitalized patients, substance use disorder (SUD) represents a growing public health crisis. Evaluating a national cohort, we aimed to characterize the association of concurrent SUD with perioperative outcomes and resource utilization following elective abdominal operations. Methods: All adult hospitalizations entailing elective colectomy, gastrectomy, esophagectomy, hepatectomy, and pancreatectomy were tabulated from the 2016-2020 National Inpatient Sample. Patients with concurrent substance use disorder, comprising alcohol, opioid, marijuana, sedative, cocaine, inhalant, hallucinogen, or other psychoactive/stimulant use, were considered the SUD cohort (others: nSUD). Multivariable regression models were constructed to evaluate the independent association between SUD and key outcomes. Results: Of ∼1,088,145 patients, 32,865 (3.0 %) comprised the SUD cohort. On average, SUD patients were younger, more commonly male, of lowest quartile income, and of Black race. SUD patients less frequently underwent colectomy, but more often pancreatectomy, relative to nSUD.Following risk adjustment and with nSUD as reference, SUD demonstrated similar likelihood of in-hospital mortality, but remained associated with increased odds of any perioperative complication (Adjusted Odds Ratio [AOR] 1.17, CI 1.09-1.25). Further, SUD was linked with incremental increases in adjusted length of stay (ß + 0.90 days, CI +0.68-1.12) and costs (ß + $3630, CI +2650-4610), as well as greater likelihood of non-home discharge (AOR 1.54, CI 1.40-1.70). Conclusions: Concurrent substance use disorder was associated with increased complications, resource utilization, and non-home discharge following major elective abdominal operations. Novel interventions are warranted to address increased risk among this vulnerable population and address significant disparities in postoperative outcomes.

Association of rurality with short-term outcomes of peripheral vascular trauma.

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.

Current Status of Contralateral Prophylactic Mastectomy: Investigating Structural Racial Disparity.

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.

Trends, outcomes, and factors associated with in-hospital opioid overdose following major surgery.

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.

Association of prior bariatric surgery with outcomes following emergency general surgery.

BACKGROUND: Despite the favorable outcomes and safety profile associated with metabolic and bariatric surgery (MBS), complications may occur postoperatively, necessitating emergency general surgery (EGS) intervention. OBJECTIVES: To evaluate the association of outcomes in patients with prior MBS following EGS interventions. SETTING: Academic, University-affiliated; USA. METHODS: All adults undergoing nonelective EGS operations were identified using the 2016 to 2020 Nationwide Readmission Database. Patients with a history of MBS were subsequently categorized as Bariatric, with the remainder of patients as NonBariatric. The primary outcome of interest was in-hospital mortality, while perioperative complications, length of stay (LOS), hospitalization costs, non-home discharge, and 30-day readmission were secondarily assessed. Multivariable regression models were developed to evaluate the association of history of MBS with outcomes of interest. RESULTS: Of an estimated 632,375 hospitalizations for EGS operations, 29,112 (4.6%) had a history of MBS. Compared to Nonbariatric, Bariatric were younger, more frequently female and more commonly had severe obesity. Following risk adjustment, Bariatric had significantly lower odds of in-hospital mortality (AOR .83, 95%CI .71-.98). Compared to others, Bariatric had reduced LOS by .5 days (95%CI .4-.7) and hospitalization costs by $1600 (95%CI $900-2100). Patients with prior MBS had reduced odds of nonhome discharge (AOR .89, 95%CI .85-.93) and increased likelihood of 30-day readmissions (AOR 2.32, 95%CI 1.93--2.79) following EGS. CONCLUSIONS: Prior MBS is associated with decreased mortality and perioperative complications as well as reduced resource utilization in select EGS procedures. Our findings suggest that patients with a history of MBS can be managed effectively by acute surgical interventions.

Off-Pump Coronary Artery Bypass Grafting Does Not Confer Superior Outcomes Among Frail Patients.

Off-pump coronary revascularization (OPCAB) has been proposed to benefit patients who are at a greater surgical risk because it avoids the use of extracorporeal circulation. Although, historically, older patients were considered high-risk candidates, recent studies implicate frailty as a more comprehensive measure of perioperative fitness. Yet, the outcomes of OPCAB in frail patients have not been elucidated. Thus, using a national cohort of frail patients, we assessed the impact of OPCAB relative to on-pump coronary revascularization (ONCAB). Patients who underwent first-time elective coronary revascularization were tabulated from the 2010 to 2020 Nationwide Readmissions Database. Frailty was assessed using the previously-validated Johns Hopkins Adjusted Clinical Groups indicator. Multivariable models were used to consider the independent associations between OPCAB and the key outcomes. Of ∼26,529 frail patients, 6,322 (23.8%) underwent OPCAB. After risk adjustment and compared with ONCAB, OPCAB was linked with similar odds of in-hospital mortality but greater likelihood of postoperative cardiac arrest (adjusted odds ratio [AOR] 1.53, confidence interval [CI] 1.13 to 2.07) and myocardial infarction (AOR 1.44, CI 1.23 to 1.69). OPCAB was further associated with greater odds of postoperative infection (AOR 1.22, CI 1.02 to 1.47) but decreased need for blood transfusion (AOR 0.68, CI 0.60 to 0.77). In addition, OPCAB faced a +0.86-day increase in length of stay (CI 0.21 to 1.51) but similar costs (ß $1,610, CI -$1,240 to 4,460) relative to ONCAB. Although OPCAB was associated with no difference in mortality compared with ONCAB, it was linked with greater likelihood of postoperative cardiac arrest and myocardial infarction. Our findings demonstrate that ONCAB remains associated with superior outcomes, even in the growing population of frail patients who underwent coronary revascularization.

Percutaneous cholecystostomy tube placement as a bridge to cholecystectomy for grade III acute cholecystitis: A national analysis.

Introduction: Percutaneous cholecystostomy (PCT) is an alternative to cholecystectomy (CCY) in high-risk surgical candidates with severe acute cholecystitis. A subset of these patients ultimately undergo delayed CCY. We therefore compared outcomes of delayed CCY in patients with grade III acute cholecystitis who received a PCT on index admission, to those who did not. Methods: Non-elective adult hospitalizations for grade III acute cholecystitis that underwent delayed CCY were identified in the 2016-2020 Nationwide Readmission Database. Patients who received a PCT during their index admission comprised the PCT group (others: Non-PCT). Outcomes were assessed for the CCY hospitalization. Entropy balancing was used to generate sample weights to adjust for differences in baseline characteristics. Regression models were created to evaluate the association between PCT and the outcomes of interest. Results: Of an estimated 13,782 patients, 13.3 % comprised PCT. Compared to Non-PCT, PCT were older (71.1 ± 13.1 vs 67.4 ± 15.3 years) and more commonly in the highest income quartile (22.5 vs 16.1 %, both p < 0.001). After risk adjustment, PCT was associated with reduced odds of respiratory (AOR 0.67, CI 0.54-0.83) and infectious (AOR 0.77, CI 0.62-0.96) complications after eventual CCY. Finally, PCT had comparable pLOS (ß +0.31, CI [-0.14, 0.77]) and operative hospitalization costs (ß $800, CI [-2300, +600]). Conclusion: In the present study, PCT was associated with decreased odds of perioperative complications and comparable resource utilization upon readmission CCY. Our findings suggest that PCT may be helpful in bridging patients with grade III acute cholecystitis to eventual CCY.

Impact of Early Tracheostomy After Lung Transplantation: A National Analysis.

BACKGROUND: Prolonged mechanical ventilation is common among lung transplant recipients, affecting nearly one-third of patients. Tracheostomy has been shown as a beneficial alternative to endotracheal intubation, but delays in tracheostomy tube placement persist. To date, no large-scale study has investigated the effect of tracheostomy timing on posttransplant outcomes. METHODS: All adults receiving tracheostomy after primary, isolated lung transplantation were identified in the 2016 to 2020 Nationwide Readmissions Database. Early tracheostomy was defined as placement before postoperative day 8 based on exploratory cohort analysis. Multivariable regression was used to evaluate the association of early tracheostomy with in-hospital mortality, select posttransplant complications, and resource utilization. RESULTS: Of an estimated 11,048 patients undergoing first-time lung transplantation, 1509 required a tracheostomy in the postoperative period, with 783 (51.9%) comprising the early cohort. After entropy balancing and risk adjustment, early tracheostomy placement was associated with reduced odds of death (adjusted odds ratio, 0.59; 95% CI, 0.36-0.97) and posttransplant infection (adjusted odds ratio, 0.54; 95% CI, 0.35-0.82). Further, tracheostomy within 1 week of transplantation was associated with decreased length of stay (ß-coefficient, -16.5 days; 95% CI, -25.3 to -7.6 days) and index hospitalization costs (ß-coefficient, -$97,600; 95% CI, -$153,000 to -$42,100). CONCLUSIONS: The present study supports the safety of early tracheostomy among lung transplant recipients and highlights several potential benefits. Among appropriately selected patients, tracheostomy placement before postoperative day 8 may facilitate early discharge, lower costs, and reduced odds of posttransplant infection.
