Association of opioid use disorder with outcomes of hospitalizations for acute myocardial infarction in the United States. Clinics (Sao Paulo) 2023; 78:100251. [PMID: 37473624 PMCID: PMC10372160 DOI: 10.1016/j.clinsp.2023.100251] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Revised: 06/27/2023] [Accepted: 07/03/2023] [Indexed: 07/22/2023] Open
Abstract
OBJECTIVE While Opioid Use Disorder (OUD) has been linked to inferior clinical outcomes, studies examining the clinical outcomes and readmission of OUD patients experiencing Acute Myocardial Infarction (AMI) remain lacking. The authors analyze the clinical and financial outcomes of OUD in a contemporary cohort of AMI hospitalizations. METHODS All non-elective adult (≥ 18 years) hospitalizations for AMI were tabulated from the 2016‒2019 Nationwide Readmissions Database using relevant International Classification of Disease codes. Patients were grouped into OUD and non-OUD cohorts. Bivariate and regression analyses were performed to identify the independent association of OUD with outcomes after non-elective admission for AMI, as well as subsequent readmission. RESULTS Of an estimated 3,318,257 hospitalizations for AMI meeting study criteria, 36,057 (1.1%) had a concomitant diagnosis of OUD. While OUD was not significantly associated with mortality, OUD patients experienced superior cardiovascular outcomes compared to non-OUD. However, OUD was linked to increased odds of non-cardiovascular complications, length of stay, costs, non-home discharge, and 30-day non-elective readmission. CONCLUSIONS Patients with OUD presented with AMI at a significantly younger age than non-OUD. While OUD appears to have a cardioprotective effect, it is associated with several markers of increased resource use, including readmission. The present findings underscore the need for a multifaceted approach to increasing social services and treatment for OUD at index hospitalization.

Abstract
BACKGROUND The link between obesity and poor outcomes in heart failure (HF) has been well-established. OBJECTIVES This retrospective study sought to examine national rates and outcomes of acute HF hospitalizations in obese individuals with a prior history of bariatric surgery. SETTING Academic, university-affiliated; the United States. METHODS Adult admissions (≥18 years) including a diagnosis of severe obesity were identified in the 2016-2019 Nationwide Readmissions Database. Patients who previously underwent bariatric operations were categorized into the Bariatric cohort. Multivariable linear and logistic models were used to assess the association of prior bariatric surgery with outcomes of interest. RESULTS Of an estimated 10,343,828 admissions for a diagnosis of severe obesity, 925,716 (8.9%) comprised the bariatric cohort. After risk adjustment, bariatric surgery was associated with significantly decreased odds of acute HF hospitalization (adjusted odds ratio [AOR]: .40, 95% confidence interval [CI]: .38-.41). Among acute HF hospitalizations, prior bariatric surgery was linked to lower odds of mortality (AOR: .68, 95% CI: .52-.89), prolonged mechanical ventilation (AOR .44, 95% CI: .32-.61), acute renal failure (AOR: .76, 95% CI: .70-.82), and prolonged hospitalization (AOR: .77, 95% CI: .68-.87). Bariatric surgery was linked to a decrement of 1 day (95% CI: .7-1.1) and $1200 in hospitalization costs (95% CI: 400-1900), but no significant difference in odds of 30-day readmission. CONCLUSIONS Bariatric surgery is associated with reduced admissions for acute HF. Among acute HF hospitalizations, bariatric surgery is linked to significantly improved clinical and financial outcomes. Given its potential benefits in obesity and related diseases, bariatric surgery holds promise for promoting value-based healthcare for HF.

Does universal insurance influence disparities in high-quality hospital use for inpatient pediatric congenital heart defect care within the first year of diagnosis? BMC Health Serv Res 2023; 23:702. [PMID: 37381049 DOI: 10.1186/s12913-023-09668-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Accepted: 06/07/2023] [Indexed: 06/30/2023] Open
Abstract
BACKGROUND Healthcare disparities are an issue in the management of Congenital Heart Defects (CHD) in children. Although universal insurance may mitigate racial or socioeconomic status (SES) disparities in CHD care, prior studies have not examined these effects in the use of High-Quality Hospitals (HQH) for inpatient pediatric CHD care in the Military Healthcare System (MHS). To assess for racial and SES disparities in inpatient pediatric CHD care that may persist despite universal insurance coverage, we performed a cross-sectional study of the HQH use for children treated for CHD in the TRICARE system, a universal healthcare system for the U.S. Department of Defense. In the present work we evaluated for the presence of disparities, like those seen in the civilian U.S. healthcare system, among military ranks (SES surrogate) and races and ethnicities in HQH use for pediatric inpatient admissions for CHD care within a universal healthcare system (MHS). METHODS We conducted a cross-sectional study using claims data from the U.S. MHS Data Repository from 2016 to 2020. We identified 11,748 beneficiaries aged 0 to 17 years who had an inpatient admission for CHD care from 2016 to 2020. The outcome variable was a dichotomous indicator for HQH utilization. In the sample, 42 hospitals were designated as HQH. Of the population, 82.9% did not use an HQH at any point for CHD care and 17.1% used an HQH at some point for CHD care. The primary predictor variables were race and sponsor rank. Military rank has been used as an indicator of SES status. Patient demographic information at the time of index admission post initial CHD diagnosis (age, gender, sponsor marital status, insurance type, sponsor service branch, proximity to HQH based on patient zip code centroid, and provider region) and clinical information (complexity of CHD, common comorbid conditions, genetic syndromes, and prematurity) were used as covariates in multivariable logistic regression analysis. RESULTS After controlling for demographic and clinical factors including age, gender, sponsor marital status, insurance type, sponsor service branch, proximity to HQH based on patient zip code centroid, provider region, complexity of CHD, common comorbid conditions, genetic syndromes, and prematurity, we did not find disparities in HQH use for inpatient pediatric CHD care based upon military rank. After controlling for demographic and clinical factors, lower SES (Other rank) was less likely to use an HQH for inpatient pediatric CHD care; OR of 0.47 (95% CI of 0.31 to 0.73). CONCLUSIONS We found that for inpatient pediatric CHD care in the universally insured TRICARE system, historically reported racial disparities in care were mitigated, suggesting that this population benefitted from expanded access to care. Despite universal coverage, SES disparities persisted in the civilian care setting, suggesting that universal insurance alone cannot sufficiently address differences in SES disparities in CHD care. Future studies are needed to address the pervasiveness of SES disparities and potential interventions to mitigate these disparities such as a more comprehensive patient travel program.

Abstract
Background Venous thromboembolism (VTE) remains under-studied among patients undergoing kidney, liver and pancreas (abdominal) transplantation. We characterized the risk and predictors of VTE using a nationally-representative cohort. Methods The 2014-2019 Nationwide Readmissions Database was queried to identify all adults undergoing abdominal transplantation. Patients who developed pulmonary embolism or deep venous thrombosis were considered the VTE cohort (others: nonVTE). Multivariable models were developed to identify factors linked with VTE and assess the independent associations between VTE and key outcomes. Results Of ~141,977 transplant recipients, 1.9 % (2722) developed VTE. The VTE cohort was similarly female (39.2 vs 38.0, p = 0.51), but more often demonstrated a higher Elixhauser comorbidity index (4.19 ± 1.40 vs 3.93 ± 1.39, p < 0.001).After adjustment, congestive heart failure (AOR 1.54, 95%CI 1.25-1.91), cardiac arrhythmias (AOR 1.54, 95%CI 1.34-1.78), peripheral vascular disease (AOR 1.29, 95%CI 1.02-1.63), coagulopathies (AOR 1.63, 95%CI 1.38-1.92), previous history of VTE (AOR 1.14, 95%CI 1.06-1.22), and heparin-induced thrombocytopenia (AOR 2.61, 95%CI 2.07-3.28) were associated with VTE. The development of VTE was linked with significantly greater in-hospital mortality (AOR 4.56, 95%CI 2.07-10.10), as well as infectious (AOR 2.59, 95%CI 1.55-4.21), cardiac (AOR 2.59, 95%CI 1.39-4.82), and respiratory (AOR 1.78, 95%CI 1.21-2.63) complications. VTE was further associated with increased length of stay (+8.18 days, 95%CI +1.32-15.41), expenditures (+$42,000, 95%CI $24,800-59,210), and odds of VTE upon readmission (AOR 4.51, 95%CI 1.32-15.41). Conclusions VTE after abdominal transplantation is linked with significantly greater in-hospital mortality, complications, resource utilization, and risk of VTE at readmission. Novel risk assessments and prophylaxis protocols are needed to reduce VTE incidence and sequelae.

Abstract
Background While the impact of socioeconomic status (SES) on surgical outcomes has been examined in limited series, it remains a significant determinant of healthcare outcomes at the national level. Therefore, the current study aims to determine SES disparities at three time-points: hospital accessibility, in-hospital outcomes, and post-discharge consequences. Methods The Nationwide Readmissions Database 2010-2018 was used to isolate major elective operations. SES was assigned using previously coded median income quartiles as defined by patient zip-code, with low SES defined as the lowest quartile and high SES as the highest. Results Of an estimated 4,816,837 patients undergoing major elective operations, 1,037,689 (21.3 %) were categorized as low SES and 1,288,618 (26.5 %) as high. On univariate analysis and compared to those of low SES, high SES patients were more frequently treated at high-volume centers (70.9 vs 55.6 %, p < 0.001), had lower rates of in-hospital complications (24.0 vs 29.0 %, p < 0.001) and mortality (0.4 vs 0.9 %, p < 0.001) as well as less frequent urgent readmissions at 30- (5.7 vs 7.1 %, p < 0.001) and 90-day timepoints (9.4 vs 10.7 %, p < 0.001). On multivariable analysis, high SES patients had higher odds of treatment at high-volume centers (Odds: 1.87, 95 % CI: 1.71-2.06), and lower odds of perioperative complications (Odds: 0.98, 95 % CI: 0.96-0.99), mortality (Odds: 0.70, 95 % CI: 0.65-0.75), and urgent readmissions at 90-days (Odds: 0.95, 95 % CI: 0.92-0.98). Conclusion This study fills a much-needed gap in the current literature by establishing that all of the aforementioned timepoints include significant disadvantages for those of low socioeconomic status. Therefore, a multidisciplinary approach may be required for intervention to improve equity for surgical patients.

Abstract
Introduction Due to immunosuppression and underlying comorbidities, transplant recipients represent a vulnerable population following emergency general surgery (EGS) operations. The present study sought to evaluate clinical and financial outcomes of transplant patients undergoing EGS. Methods The 2010-2020 Nationwide Readmissions Database was queried for adults (≥18 years) with non-elective EGS. Operations included bowel resection, perforated ulcer repair, cholecystectomy, appendectomy and lysis of adhesions. Patients were classified by transplant history (Non-transplant, Kidney/Pancreas, Liver, Heart/Lung). The primary outcome was in-hospital mortality while perioperative complications, resource utilization and readmissions were secondarily considered. Multivariable regression models evaluated the association of transplant status on outcomes. Entropy balancing was employed to obtain a weighted comparison to adjust for intergroup differences. Results Of 7,914,815 patients undergoing EGS, 25,278 (0.32 %) had prior transplantation. The incidence of transplant patients increased temporally (2010: 0.23 %, 2020: 0.36 %, p < 0.001) with Kidney/Pancreas comprising the largest proportion (63.5 %). Non-transplant more frequently underwent appendectomy and cholecystectomy while transplant patients more commonly received bowel resections. Following entropy balancing, Liver was associated with decreased odds of mortality (AOR: 0.67, 95 % CI: 0.54-0.83, Reference: Non-transplant). Incremental hospitalization duration was longer in Liver and Heart/Lung compared to Non-transplant. Odds of acute kidney injury, readmissions and costs were higher in all transplant types. Conclusion The incidence of transplant recipients undergoing EGS operations has increased. Liver was observed to have lower mortality compared to Non-transplant. Transplant recipient status, regardless of organ, was associated with greater resource utilization and non-elective readmissions. Multidisciplinary care coordination is warranted to mitigate outcomes in this high-risk population.

Abstract
BACKGROUND Financial toxicity, or the impact out-of-pocket medical expenses have on the quality of life, has not been widely enumerated in the trauma literature. We characterized the relationship between insurance status and the risk of financial toxicity after trauma and associated risk factors. METHODS Adults admitted for gunshot wounds, other penetrating injuries, or blunt assault were identified from the 2015 to 2019 National Inpatient Sample. The outcome of interest was a risk of financial toxicity with separate regression models for uninsured and insured populations. RESULTS Of an estimated 775,665 patients, 21.2% were at risk of financial toxicity. Patients at risk of financial toxicity were younger, more commonly male, less commonly White, and had a lower Elixhauser Index (Table 1). A higher proportion of uninsured patients were at risk of financial toxicity (40.8% vs 17.7%, P < .001) than insured patients. Whereas the proportion of uninsured patients at risk of financial toxicity significantly increased from 2015 to 2019, it was unchanged in insured patients. After adjustment, non-income demographic and clinical factors were not associated with the risk of financial toxicity amongst the insured. Conversely, the Black or Hispanic race, gunshot wounds, and any in-hospital complications were some factors associated with increased risk of financial toxicity in uninsured patients. CONCLUSION An increasingly larger proportion of uninsured patients are at risk of financial toxicity after trauma. The risk of financial toxicity among the uninsured was more complex than in the insured and associated with race, gunshot wounds, and complications. Increasing insurance access and the adoption of trauma-informed care practices should be used to address financial toxicity in this population.

Abstract
BACKGROUND Sociodemographic disparities in atrial fibrillation (AF) management and thromboembolic prophylaxis have previously been reported, which may involve inequitable access to left atrial appendage occlusion (LAAO) during cardiac surgery. The present study aimed to evaluate the association of LAAO utilization with sex, race, and hospital region among patients with AF undergoing heart valve operations. METHODS Adults with AF undergoing valve replacement/repair in the 2012-2019 National Inpatient Sample were identified and stratified based on concurrent LAAO. Multivariable linear and logistic regressions were developed to identify factors associated with LAAO utilization. Mortality, complications including stroke and thromboembolism, hospitalization costs and length of stay (LOS) were secondarily assessed. RESULTS Of 382,580 patients undergoing valve operations, 18.7% underwent concomitant LAAO. Over the study period, the proportion of female patients receiving LAAO significantly decreased from 44.8% to 38.9% (p<0.001). Upon risk adjustment, female (AOR 0.93 [95% CI 0.89-0.97]) and Black patients (0.91 [0.83-0.99]) had significantly reduced odds of undergoing LAAO compared to males and Whites, respectively. Additionally, hospitals in the Midwest (1.38 [1.24-1.51]) and West (1.26 [1.15-1.36]) had increased likelihood of LAAO whereas Northeast hospitals (0.85 [0.77-0.94)] had decreased odds relative to the South. Furthermore, LAAO was associated with decreased stroke (0.71 [0.60-0.84]) and thromboembolism (0.68 [0.54-0.86]), $4,200 reduction in costs and 1-day decrement in LOS. CONCLUSIONS Female and Black patients had significantly lower odds while Midwest and Western hospitals had greater odds of LAAO utilization. Enhancing access to LAAO during valvular surgery is warranted to improve clinical and financial outcomes for patients with AF.

Abstract
BACKGROUND While safety-net hospitals (SNH) play a critical role in the care of underserved communities, they have been associated with inferior postoperative outcomes. This study evaluated the association of hospital safety-net status with clinical and financial outcomes following esophagectomy. METHODS All adults (≥18 years) undergoing elective esophagectomy for benign and malignant gastroesophageal disease were identified in the 2010-2019 Nationwide Readmissions Database. Centers in the highest quartile for the proportion of uninsured/Medicaid patients were classified as SNH (others: non-SNH). Regression models were developed to evaluate adjusted associations between SNH status and outcomes, including in-hospital mortality, perioperative complications, and resource use. Royston-Parmar flexible parametric models were used to assess time-varying hazard of non-elective readmission over 90 days. RESULTS Of an estimated 51,649 esophagectomy hospitalizations, 9,024 (17.4%) were performed at SNH. While SNH patients less frequently suffered from gastroesophageal malignancies (73.2 vs 79.6%, p<0.001) compared to non-SNH, the distribution of age and comorbidities were similar. SNH was independently associated with mortality (AOR 1.24, 95% CI 1.03-1.50), intraoperative complications (AOR 1.45, 95% CI 1.20-1.74) and need for blood transfusions (AOR 1.61, 95% CI 1.35-1.93). Management at SNH was also associated with incremental increases in LOS (+1.37, 95% CI 0.64-2.10), costs (+10,400, 95% CI 6,900-14,000), and odds of 90-day non-elective readmission (AOR 1.11, 95% CI 1.00-1.23). CONCLUSIONS Care at safety-net hospitals was associated with higher odds of in-hospital mortality, perioperative complications, and non-elective rehospitalization following elective esophagectomy. Efforts to provide sufficient resources at SNH may serve to reduce complications and overall costs for this procedure.

Abstract
BACKGROUND Septal myectomy is the gold standard treatment for refractory hypertrophic obstructive cardiomyopathy. The present study characterized the association of septal myectomy volume and cardiac surgery volume with outcomes after septal myectomy. METHODS Adults undergoing septal myectomy for hypertrophic obstructive cardiomyopathy were identified in the 2016 to 2019 Nationwide Readmissions Database. Centers were grouped into low-, medium-, and high-volume hospitals by tertiles based on institutional septal myectomy caseload. Overall cardiac surgery volume was similarly assessed. Generalized linear models were used to test the association between hospital septal myectomy or cardiac surgery volume and in-hospital mortality, mitral valve repair, and 90-day non-elective readmission. RESULTS Of 3,337 patients, 30.8% underwent septal myectomy at high-volume hospitals, whereas 39.1% were managed at low-volume hospitals. Patients at high-volume hospitals had a similar burden of comorbidities at low-volume hospitals, although congestive heart failure was more prevalent at high-volume hospitals. Despite comparable rates of mitral regurgitation, patients more commonly avoided mitral valve intervention at high-volume hospitals compared with low-volume hospitals (72.9% vs 68.3%; P = .007). After risk adjustment, high-volume hospital status was associated with reduced odds of mortality (0.24; 95% CI, 0.08-0.77) and readmission (0.59; 95% CI, 0.3-0.97). Among cases requiring mitral intervention, high-volume hospital status was associated with greater odds of valve repair (5.33; 95% CI, 2.54-11.13) relative to low-volume hospitals. Overall cardiac surgery volume was not associated with any studied outcome. CONCLUSION Greater septal myectomy volume, but not overall cardiac surgery volume, was associated with reduced mortality and greater mitral valve repair relative to replacement after septal myectomy. These findings suggest that septal myectomy for hypertrophic obstructive cardiomyopathy should be performed at centers with expertise in this operation.

Abstract
BACKGROUND Hypoalbuminemia has been used as a surrogate for malnutrition and is associated with worse postoperative outcomes across major operations. Because patients with hiatal hernia often have inadequate caloric intake, we examined the association of serum albumin levels with outcomes after hiatal hernia repair. METHODS Adults undergoing elective and non-elective hiatal hernia repair via any approach were tabulated from the 2012 to 2019 National Surgical Quality Improvement Program. Patients were stratified into the Hypoalbuminemia cohort if serum albumin <3.5 mg/dL using restricted cubic spline analysis. Major adverse events were defined as a composite of all-cause mortality and major complications per the American College of Surgeons National Surgical Quality Improvement Program risk calculator. Entropy balancing was used to adjust for intergroup differences. Multivariable regression models were then constructed to assess the association of preoperative albumin with major adverse events, postoperative length of stay, and 30-day readmission. RESULTS Of 23,103 patients, 11.7% comprised the Hypoalbuminemia cohort. The Hypoalbuminemia group was older, less commonly of White race, and less likely to have an independent functional status than others. They were also more likely to undergo inpatient, non-elective surgery via laparotomy. After entropy balancing and adjustment, hypoalbuminemia remained associated with increased odds of major adverse events and multiple complications and longer adjusted postoperative length of stay. There was no significant difference in adjusted odds of readmission. CONCLUSION We used a quantitative methodology to establish a serum albumin threshold of 3.5 mg/dL associated with increased adjusted odds of major adverse events, increased postoperative length of stay, and postoperative complications after hiatal hernia repair. These results may guide preoperative nutrition supplementation.

Abstract
BACKGROUND Coronary artery bypass surgery in octogenarians is associated with increased postoperative morbidity. Off-pump coronary artery bypass surgery eliminates potential complications of cardiopulmonary bypass, but its use remains controversial. This study aimed to evaluate the clinical and financial impact of off-pump coronary artery bypass surgery compared to conventional coronary artery bypass surgery among this high-risk population. METHODS Patients ≥80 years undergoing first-time, isolated, elective coronary artery bypass surgery were identified using the 2010-2019 Nationwide Readmissions Database. Patients were grouped into off-pump or conventional coronary artery bypass surgery cohorts. Multivariable models were developed to assess the independent associations between off-pump coronary artery bypass surgery and key outcomes. RESULTS Of ∼56,158 patients, 13,940 (24.8%) underwent off-pump coronary artery bypass surgery. On average, the off-pump cohort was more likely to undergo single-vessel bypass (37.3 vs 19.7%, P < .001). After adjustment, undergoing off-pump coronary artery bypass surgery was associated with similar odds of in-hospital mortality (adjusted odds ratio 0.90, 95% confidence interval 0.73-1.12) relative to conventional bypass. Additionally, the off-pump and conventional coronary artery bypass surgery groups were comparable in odds of postoperative stroke (adjusted odds ratio 1.03, 95% confidence interval 0.78-1.35), cardiac arrest (adjusted odds ratio 0.99, 95% confidence interval 0.71-1.37), ventricular fibrillation (adjusted odds ratio 0.89, 95% confidence interval 0.60-1.31), tamponade (adjusted odds ratio 1.21, 95% confidence interval 0.74-1.97), and cardiogenic shock (adjusted odds ratio 0.94, 95% confidence interval 0.75-1.17). However, the off-pump coronary artery bypass surgery cohort was linked with an increased likelihood of ventricular tachycardia (adjusted odds ratio 1.23, 95% confidence interval 1.01-1.49) and myocardial infarction (adjusted odds ratio 1.34, 95% confidence interval 1.16-1.55). Furthermore, those undergoing off-pump coronary artery bypass surgery demonstrated reduced odds of non-home discharge (adjusted odds ratio 0.91, 95% confidence interval 0.83-0.99) and a decrement in hospitalization expenditures ($-1,290, 95% confidence interval -$2,370 to $200). CONCLUSION Off-pump coronary artery bypass surgery was linked with increased odds of ventricular tachycardia and myocardial infarction, but no difference in mortality. Our findings point to the safety of conventional coronary artery bypass surgery in octogenarians. Yet, future work is needed to consider long-term outcomes in this complex surgical cohort.

Abstract
Background Guidelines for choice of prosthetic heart valve in people of reproductive age are not well established. Although biologic heart valves (BHVs) have risk of deterioration, mechanical heart valves (MHVs) require lifelong anticoagulation. This study aimed to characterize the association of prosthetic valve type with maternal and fetal outcomes in pregnant patients. Methods and Results Using the 2008 to 2019 National Inpatient Sample, we identified all adult patients hospitalized for delivery with prior heart valve implantation. Multivariable regressions were used to analyze the primary outcome, major adverse cardiovascular events, and secondary outcomes, including maternal and fetal complications, length of stay, and costs. Among 39 871 862 birth hospitalizations, 4152 had MHVs and 874 had BHVs. Age, comorbidities, and cesarean birth rates were similar between patients with MHVs and BHVs. The presence of a prosthetic valve was associated with over 22-fold increase in likelihood of major adverse cardiovascular events (MHV: adjusted odds ratio, 22.1 [95% CI, 17.3-28.2]; BHV: adjusted odds ratio, 22.5 [95% CI, 13.9-36.5]) as well as increased duration of stay and hospitalization costs. However, patients with MHVs and BHVs had no significant difference in the odds of any maternal outcome, including major adverse cardiovascular events, hypertensive disease of pregnancy, and ante/postpartum hemorrhage. Similarly, fetal complications were more likely in patients with valve prostheses, including a 4-fold increase in odds of stillbirth, but remained comparable between MHVs and BHVs. Conclusions Patients hospitalized for delivery with prior valve replacement carry substantial risk of adverse maternal and fetal events, regardless of valve type. Our findings reveal comparable outcomes between MHVs and BHVs.

Abstract
BACKGROUND Traditional quality metrics like one-year survival do not fully encapsulate the multifaceted nature of solid organ transplantation in contemporary practice. Therefore, investigators have proposed using a more comprehensive measure, the textbook outcome. However, the textbook outcome remains ill-defined in the setting of heart transplantation. METHODS Within the Organ Procurement and Transplantation Network database, the textbook outcome was defined as having: (1) No postoperative stroke, pacemaker insertion, or dialysis, (2) no extracorporeal membrane oxygenation requirement within 72 hours of transplantation, (3) index length of stay <21 days, (4) no acute rejection or primary graft dysfunction, (5) no readmission for rejection or infection, or re-transplantation within one year, and (6) an ejection fraction >50% at one year. RESULTS Of 26,885 heart transplantation recipients between 2011 to 2022, 9,841 (37%) achieved a textbook outcome. Following adjustment, textbook outcome patients demonstrated significantly reduced hazard of mortality at 5- (hazard ratio 0.71, 95% CI 0.65-0.78; P < .001) and 10-years (hazard ratio 0.73, CI 0.68-0.79; P < .001), and significantly greater likelihood of graft survival at 5- (hazard ratio 0.69, CI 0.63-0.75; P < .001) and 10-years (hazard ratio 0.72, CI 0.67-0.77; P < .001). Following estimation of random effects, hospital-specific, risk-adjusted rates of textbook outcome ranged from 39% to 91%, compared to a range of 97% to 99% for one-year patient survival. Multi-level modeling of post-transplantation rates of textbook outcomes revealed that 9% of the variation between transplant programs was attributable to inter-hospital differences. CONCLUSION Textbook outcomes offer a nuanced, composite alternative to using one-year survival when evaluating heart transplantation outcomes and comparing transplant program performance.

Abstract
BACKGROUND Despite evidence suggesting oncologic equipoise of breast conservation therapy (BCT) for early-stage (stages I and II) breast cancer, mastectomy is still widely utilized. PATIENTS AND METHODS The 2004-2015 National Cancer Database was used to tabulate all adult women receiving mastectomy or BCT for early-stage breast cancer. Multivariable regression was used to evaluate factors associated with utilization of BCT, relative to mastectomy. RESULTS Of 1,079,057 women meeting study criteria, 57.4% underwent BCT. BCT patients were older and more commonly White, compared to mastectomy. They were more commonly privately insured, in the highest income quartile, and treated at metropolitan, nonacademic institutions. After adjustment, increasing age (AOR 1.01/year), Black race (AOR 1.21, Ref: White), and care at a community hospital (AOR 1.08, Ref: Academic; all P< .05) were associated with increased odds of undergoing BCT. Conversely, Asian or Pacific Islander (AAPI) race (AOR 0.74), Medicare (AOR 0.89) or Medicaid (AOR 0.95) coverage, and being in the lowest (AOR 0.95) and second lowest (AOR 0.98, all P< .05) income quartiles were associated with reduced odds of undergoing BCT. Finally, increasing tumor size (AOR 0.97, P< .05) was associated with decreased adjusted odds of undergoing BCT. CONCLUSION Our results suggest persistent socioeconomic and racial disparities in BCT utilization for early-stage breast cancer. Directed strategies should be implemented in order to reduce treatment inequality in this patient population.

Abstract
BACKGROUND The incidence of thyroid pathology increases with age. Yet octogenarians may face increased rates of complications after thyroid surgery. Using a nationally representative cohort, we evaluated the outcomes of thyroidectomy among octogenarians. METHODS All patients ≥55 years who underwent inpatient thyroidectomy were identified using the 2010 to 2020 National Readmissions Database. Patients ≥80 years were classified as octogenarians (others: nonoctogenarians). Multivariable models were built to evaluate independent associations between octogenarians and key clinical and financial outcomes. RESULTS Of 120,164 hospitalizations, 9,163 (7.6%) were octogenarians. The proportion of octogenarians undergoing thyroidectomy increased from 7.7% (2010) to 8.7% (2020) (nptrend <0.001). Octogenarians were more frequently female (72.1 vs 70.5%, P < .001), presented with a higher Elixhauser comorbidity index (3 [2-4] vs 2 [1-3], P < .001), and more commonly faced thyroid cancer (41.3 vs 32.7%, P < .001). After risk adjustment, octogenarians were associated with greater odds of experiencing any perioperative complication (adjusted odds ratio 1.36, 95% confidence interval 1.25-1.48). Octogenarians were further linked with greater odds of respiratory (adjusted odds ratio 1.82, 95% confidence interval 1.52-2.17) and renal complications (adjusted odds ratio 1.90, 95% confidence interval 1.45-2.49), dysphagia (adjusted odds ratio 1.51, 95% confidence interval 1.33-1.72), laryngeal edema (adjusted odds ratio 2.03, 95% confidence interval 1.30-3.18), vocal cord paralysis (adjusted odds ratio 1.79, 95% confidence interval 1.53-2.09), and stridor (adjusted odds ratio 1.42, 95% confidence interval 1.01-2.00). No difference in hypocalcemia was observed. Furthermore, octogenarians demonstrated an increased likelihood of in-hospital mortality (adjusted odds ratio 6.34, 95% confidence interval 3.11-12.53), hospitalization expenditures (+$910, 95% confidence interval +$420-1,400), and nonelective readmission within 30 days of discharge (adjusted odds ratio 1.54, 95% confidence interval 1.32-1.79). CONCLUSION Octogenarians are associated with greater morbidity after thyroidectomy. Patients ≥80 years should be counseled about increased perioperative risk when discussing surgical versus nonsurgical treatments for thyroid disease.

Abstract
BACKGROUND To assess the use of surgical intervention for lower gastrointestinal bleeding and evaluate its associated factors. METHODS The 2016 to 2019 National Inpatient Sample was queried to identify non-elective adult (≥18 years) hospitalizations for lower gastrointestinal bleeding. The International Classification of Diseases, 10th Revision, codes were used to ascertain patient characteristics, including signs of hemodynamic instability, potential lower gastrointestinal bleed source, and transfusion of blood products, as well as endoscopic, radiologic, and surgical intervention. Multivariable regression analyses were used to elucidate factors associated with operative management of lower gastrointestinal bleeding and evaluate its associated mortality, length of stay, and hospitalization costs. RESULTS Of an estimated 364,495 patients, 1.7% underwent an operation for lower gastrointestinal bleeding. Compared to those managed conservatively, patients who underwent surgical intervention more commonly had diverticular-related bleeding, signs of hypovolemia, and less frequently underwent endoscopic intervention. After the adjustment of patient and hospital characteristics, ischemic colitis (adjusted odds ratio 7.5, 95% confidence interval 1.8-30.9, ref: hemorrhoids), hemodynamic instability (adjusted odds ratio 1.7, 95% confidence interval 1.5-2.0), and angiographic embolization (adjusted odds ratio 4.9, 95% confidence interval 3.9-6.0, ref: no endoscopic/radiologic intervention) were associated with greater odds of surgical intervention. Additionally, surgical intervention portended greater odds of in-hospital mortality (adjusted odds ratio 6.2, 95% confidence interval 4.5-8.5), a longer length of stay (8.5 days, 95% confidence interval 8.0-9.0), and greater hospitalization cost ($29.1K, 95% confidence interval 26.7K-31.5K). CONCLUSION Operative management of lower gastrointestinal bleeding is rare and associated with significant morbidity and mortality compared to those managed conservatively. However, when surgical intervention is indicated, preoperative patient characteristics should be used to identify those at greater risk of an operation to facilitate early surgical consultation and inform expectations during the perioperative period.

Abstract
OBJECTIVE Safety-net hospitals (SNHs) have previously been associated with inferior outcomes and greater resource use. However, this relationship has not been explored in the contemporary setting of pulmonary lobectomy. In the present national study we characterized the association between SNHs and mortality, complications, and resource use. METHODS All adults (18 years of age or older) who underwent elective lobectomy for lung cancer were identified within the 2010 to 2019 Nationwide Readmissions Database. Hospitals in the highest quartile of safety-net burden were categorized as SNHs, and others non-SNHs. Multivariable regressions were developed to assess the independent association between safety-net status and outcomes of interest. RESULTS Of an estimated 282,011 patients who met inclusion criteria, 41,015 (14.5%) were treated at SNHs. Patients at SNHs were younger but as commonly female, compared with non-SNHs. After multivariable adjustment, there was no association between SNHs and mortality. However, treatment at SNHs was linked to higher odds of pneumonia (adjusted odds ratio [AOR], 1.11; 95% CI, 1.02-1.21) and prolonged ventilation (AOR, 1.36; 95% CI, 1.11-1.66), as well as infectious (AOR, 1.24; 95% CI, 1.08-1.43), intraoperative (AOR, 1.22; 95% CI, 1.07-1.39), and overall complications (AOR, 1.07; 95% CI, 1.01-1.14). Patients at SNHs also showed a greater need for a blood transfusion (AOR, 1.37; 95% CI, 1.23-1.53). In addition, SNHs were associated with increased length of stay (+0.33 days; 95% CI, 0.17-0.48) and greater costs (+$4130; 95% CI, 3.34-4.92), relative to non-SNHs. CONCLUSIONS Hospital safety-net status was associated with greater odds of perioperative complications and greater health care expenditure. Further investigation is necessary uncover the mechanisms contributing to these complications and eradicate persistent disparities in lobectomy.

Abstract
BACKGROUND Metabolic surgery has been shown to partially reverse metabolic and cardiovascular derangements associated with obesity. Using a national database, we examined the association of prior metabolic surgery with outcomes after elective cardiac operations. METHODS The 2016 to 2019 Nationwide Readmissions Database was queried to identify all adult hospitalizations for elective cardiac operations. Individual comorbidities and history of metabolic surgery were ascertained using International Classification of Diseases 10th Revision diagnosis codes. Entropy balancing was used to adjust for differences in baseline characteristics between patients with and without prior metabolic surgery. Multivariable logistic and linear regressions were subsequently developed to assess the association between metabolic surgery and in-hospital mortality, perioperative complications, length of stay, costs, and 30-day unplanned readmission. RESULTS An estimated 454,506 hospitalizations entailing elective cardiac operations met inclusion criteria, of whom 3,615 (0.80%) had a diagnosis code indicating a history of metabolic surgery. Compared to their counterparts, those with prior metabolic surgery were more frequently female, younger, and had a higher burden of comorbidities as measured by the Elixhauser Comorbidity Index. After adjustment, prior metabolic surgery was associated with significantly reduced mortality (adjusted odds ratio 0.50, 95% confidence interval 0.31-0.83). Prior metabolic surgery was also linked to decreased pneumonia, prolonged mechanical ventilation, and respiratory failure. Of note, patients with a history of metabolic surgery encountered a greater likelihood of 30-day, non-elective readmission (adjusted odds ratio 1.26, 95% confidence interval 1.08-1.48). CONCLUSIONS Patients with a history of metabolic surgery had significantly reduced odds of in-hospital mortality and perioperative complications after cardiac operations but faced increased readmissions.

Abstract
BACKGROUND Generally, heart transplantation with marginal donor allografts is reserved for a subset of high-risk patients. However, given the improved survival rates for patients on left ventricular assist devices, it is worth analyzing if they could potentially substitute for marginal donor allografts. This study aimed to compare survival outcomes of waitlisted patients with left ventricular assist devices who did not undergo heart transplantation to those who underwent heart transplantation with marginal allografts. METHODS This was a retrospective cohort study of adults (≥18 years) listed for heart transplantation between 2010 and 2022 in the Organ Procurement and Transplantation Network database. A previously validated risk score was used to define marginal donor organs. The primary outcome was death after transplantation or on the waitlist, as appropriate. RESULTS Of 5,713 patients with left ventricular assist devices, 4,683 (82%) comprised the left ventricular assist devices group and 1,030 (18%) the marginal group. The marginal cohort was older (57 [49-64] vs 55 [45-62] years, P < .001), similarly female (26 vs 24%, P = .16), and less often White (51 vs 60%, P < .001). Relative to the left ventricular assist devices group, the marginal group demonstrated higher 5-year survival from 2010 to 2014 (81 vs 43%, P < .001) and from 2015 to 2019 (77 vs 66%, P < .001). After adjustment, marginal patients demonstrated a significantly reduced hazard of 5-year mortality for those listed from 2010 to 2014 (hazard ratio 0.25, confidence interval 0.20-0.31; P < .001) and from 2015 to 2019 (hazard ratio 0.46, confidence interval 0.37-0.57; P < .001). CONCLUSION Our study validates the superiority of transplantation relative to left ventricular assist devices but also underscores the survival benefit of heart transplantation with marginal donor allografts, even in high-risk patients.

Abstract
BACKGROUND Although the use of robotic-assisted surgery continues to expand, the cost-effectiveness of this platform remains unclear. The present study aimed to compare hospitalization costs and clinical outcomes between robotic-assisted surgery and laparoscopic approaches for major abdominal operations. METHODS All adults receiving minimally invasive gastrectomy, cholecystectomy, colectomy (right, left, transverse, sigmoid), ventral hernia repair, hysterectomy, and abdominoperineal resection were identified in the 2012 to 2019 National Inpatient Sample. Records with concurrent operations were excluded. Multivariable linear and logistic regressions were developed to examine the association of the operative approach with costs, length of stay, and complications. An interaction term between the year and operative approach was used to analyze cost differences over time. RESULTS Of an estimated 1,124,450 patients, 75.8% had laparoscopic surgery, and 24.2% had robotic-assisted surgery. Compared to laparoscopic, patients with robotic-assisted operations were younger and more commonly privately insured. The average hospitalization cost for laparoscopic cases was $16,000 ± 14,800 and robotic-assisted cases was $18,300 ± 13,900 (P < .001). Regardless of procedure type, all robotic-assisted operations had higher costs compared to laparoscopic operations. Risk-adjusted trend analysis revealed that the discrepancy in costs between laparoscopic and robotic-assisted surgery persisted and widened over time from $1,600 in 2012 to $2,600 in 2019. Compared to laparoscopic procedures, robotic procedures had a 2.2% reduction in complications (9.4 vs 11.6%, P < .001) and a 0.7-day decrement in the length of stay (95% confidence interval -0.8 to -0.7). CONCLUSION Disparities in costs between robotic and laparoscopic abdominal operations have persisted over time. Given the modest decrement in adverse outcomes, further investigation into the clinical benefits of robotic surgery is warranted to justify its greater costs.

Abstract
A body of literature has previously highlighted the impact of health insurance on observed disparities in congenital cardiac operations. With aims of improving access to healthcare for all patients, the Affordable Care Act (ACA) expanded Medicaid coverage to nearly all eligible children in 2010. Therefore, the present population-based study aimed to examine the association of Medicaid coverage with clinical and financial outcomes in the era the ACA. Records for pediatric patients (≤ 18 years) who underwent congenital cardiac operations were abstracted from the 2010-2018 Nationwide Readmissions Database. Operations were stratified using the Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery (STAT) Category. Multivariable regression models were developed to evaluate the association of insurance status on index mortality, 30-day readmissions, care fragmentation, and cumulative costs. Of an estimated 132,745 hospitalizations for congenital cardiac surgery from 2010 to 2018, 74,925 (56.4%) were insured by Medicaid. The proportion of Medicaid patients increased from 57.6 to 60.8% during the study period. On adjusted analysis, patients with Medicaid insurance were at an increased odds of mortality (1.35, 95%CI: 1.13-1.60) and 30-day unplanned readmission (1.12, 95%CI: 1.01-1.25), experienced longer lengths of stay (+ 6.5 days, 95%CI 3.7-9.3), and exhibited higher cumulative hospitalization costs (+ $21,600, 95%CI: $11,500-31,700). The total hospitalization cost-burden for patients with Medicaid and private insurance were $12.6 billion and $8.06 billion, respectively. Medicaid patients exhibited increased mortality, readmissions, care fragmentation, and costs compared to those with private insurance. Our results of outcome variation by insurance status indicate the necessity of policy changes to attempt to approach equality in surgical out comes for this high-risk cohort. Baseline characteristics, trends, and outcomes by insurance status over the ACA rollout period 2010-2018.

A contemporary analysis of the volume-outcome relationship for extracorporeal membrane oxygenation in the United States. Surgery 2023; 173:1405-1410. [PMID: 36914511 DOI: 10.1016/j.surg.2023.02.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 01/02/2023] [Accepted: 02/06/2023] [Indexed: 03/13/2023]
Abstract
BACKGROUND A paradoxical increase in mortality following extracorporeal membrane oxygenation at high-volume centers has previously been demonstrated. We examined the association between annual hospital volume and outcomes within a contemporary, national cohort of extracorporeal membrane oxygenation patients. METHODS All adults requiring extracorporeal membrane oxygenation for postcardiotomy syndrome, cardiogenic shock, respiratory failure, or mixed cardiopulmonary failure were identified in the 2016 to 2019 Nationwide Readmissions Database. Patients undergoing heart and/or lung transplantation were excluded. A multivariable logistic regression with hospital extracorporeal membrane oxygenation volume parametrized as restricted cubic splines was developed to characterize the risk-adjusted association between volume and mortality. The volume corresponding to the maximum of the spline (43 cases/year) was used to categorize centers as low- or high-volume. RESULTS An estimated 26,377 patients met the study criteria, and 48.7% were managed at high-volume hospitals. Patients at low- and high-volume hospitals had similar age, sex, and rates of elective admission. Notably, patients at high-volume hospitals less frequently required extracorporeal membrane oxygenation for postcardiotomy syndrome but more commonly for respiratory failure. After risk adjustment, high-volume hospital status was associated with reduced odds of in-hospital mortality, relative to low-volume hospitals (adjusted odds ratio 0.81, 95% confidence interval 0.78-0.97). Interestingly, patients at high-volume hospitals faced a 5.2-day increment in length of stay (95% confidence interval 3.8-6.5) and $23,500 in attributable costs (95% confidence interval 8,300-38,700). CONCLUSION The present study found that greater extracorporeal membrane oxygenation volume was associated with decreased mortality but higher resource use. Our findings may help inform policies regarding access to and centralization of extracorporeal membrane oxygenation care in the United States.

Perioperative Nephrectomy Outcomes for Patients with Liver Disease: Implications for Liver Transplant Candidates. Urology 2023; 173:127-133. [PMID: 36403677 DOI: 10.1016/j.urology.2022.10.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Revised: 09/26/2022] [Accepted: 10/23/2022] [Indexed: 11/19/2022]
Abstract
OBJECTIVE To improve the management of cirrhotic patients diagnosed with new renal masses, we used a nationally representative cohort to assess the perioperative outcomes of nephrectomy in the setting of liver disease. The incidences of liver disease and renal masses are both rising in the US. Delaying liver transplantation to address other health concerns may have life changing consequences in these patients, thus these results help to guide treatment decisions at this critical junction in care. METHODS A retrospective study of the 2016-2019 Nationwide Readmissions Database was performed in adults undergoing nephrectomy for non-emergent indications. Outcomes were compared between 3 cohorts: no chronic liver disease (no CLD), chronic liver disease (CLD), and decompensated cirrhosis (DC). Mixed regression models were used to evaluate the association between CLD and DC with outcomes of interest including morbidity, mortality, readmission rates, non-home discharges, length of stay, and costs. RESULTS A total of 183,362 patients were evaluated. The mortality rate in the DC cohort (7%) was higher than with CLD (0.4%) and no CLD (0.3%), (P <.001). DC was associated with higher mortality (OR 8.29, 95% CI 4.07 - 16.88), postoperative bleeding requiring transfusion (OR 5.55, 95% CI 3.72 - 8.26), non-home discharge (OR 5.12, 95% CI 3.16 - 8.30) and readmission (OR 1.79, 95% CI 1.09 - 2.94) compared to no CLD. The DC cohort had the greatest length of stay and costs. CONCLUSION Patients undergoing nephrectomy with DC have increased morbidity, mortality, readmission rates, non-home discharges, LOS and costs. Alternative management strategies may be considered in these patients.
