Abstract
OBJECTIVES Studies have demonstrated that socioeconomic status, insurance, race, and distance impact clinical outcomes in patients with abdominal aortic aneurysms. The purpose of this study was to assess if these factors also impact clinical outcomes in patients with thoracoabdominal aortic aneurysms (TAAAs). METHODS We conducted a retrospective review of patients with TAAAs confirmed by computed tomography imaging between 2009 and 2019 at a single institution. Patients' zip codes were mapped to American Community Survey Data to obtain geographic poverty rates. We used the standard U.S. Census definition of high-poverty concentration as >20% of the population living at 100% of the poverty rate. Our primary outcome was overall survival, stratified by whether the patient underwent repair. RESULTS Of 578 patients, 575 had zip code data and were analyzed. In both the nonoperative (N = 268) and operative (N = 307) groups, there were no significant differences in age, race, comorbidities, clinical urgency, surgery utilization, or surgery modality between patients living in high-poverty areas (N = 95, 16.4%) vs not. In the nonoperative group, patients from high-poverty areas were more likely to have aneurysm due to dissection (37.5% vs 17.6%, P = .03). In multivariate analyses, patients from high-poverty zip codes had significantly worse nonoperative survival (hazard ratio [HR]: 1.9, 95% confidence interval [CI]: 1.1-3.3, P = .03). In the repair group, high poverty was also a significant predictor of reduced postoperative survival (HR: 1.65, 95% CI: 1-2.63, P = .04). Adding the Gagne Index, these differences persisted in both groups (nonoperative: HR: 1.93, 95% CI: 1.01-3.70, P = .05; operative: HR: 1.62, 95% CI: 1.03-2.56, P = .04). In Kaplan-Meier analysis, the difference in postoperative survival began approximately 1.5 years after repair. Private insurance was predictive of improved postoperative survival (HR: 0.42, 95% CI: 0.18-0.95, P = .04) but reduced nonoperative survival (HR: 2.05, 95% 1.01-4.14, P = .04). Data were insufficient to determine if race impacted survival discretely from poverty status. These results were found after adjusting for age, race, sex, maximum aortic diameter, coronary artery disease, distance from the hospital, insurance, and active smoking. Interestingly, in multivariate regression, traveling greater than 100 miles was correlated with increased surgery utilization (odds ratio: 1.58, 95% CI: 1.08-2.33, P = .02) and long-term survival (HR: 0.61, 95% CI: 0.41-0.92, P = .02). CONCLUSIONS Patients with TAAAs living in high-poverty areas had significantly more dissections and suffered a nearly doubled risk of mortality compared with patients living outside such areas. These data suggest that these disparities are attributed to the overall impacts of poverty and highlight the pressing need for research into TAAA disparities.

Abstract
INTRODUCTION Low socioeconomic status (SES), distance lived from hospital, and insurance status are well documented in the literature to increase the risk of post-operative morbidity and mortality for some disease processes however there is a paucity of data regarding how this association impacts patients with peripheral artery disease (PAD). This study aimed to evaluate if SES, distance lived from hospital, and insurance status increased the risk of developing major graft failure in patients undergoing revascularization procedures for symptomatic PAD in a prospective, observation study. METHODS In this prospective, observational study, all patients undergoing lower extremity revascularization (endovascular or open) were included from December 2020 to February 2022. Demographic factors, insurance status, operative details, and median income and distance from hospital were documented through chart review. Complications were defined as thrombosis/occlusion of the revascularized vessel or bypass graft or infection of the distal wound or surgical incision wound. Univariate and multivariate analysis were performed comparing patients that developed complications and those that did not. This project was undertaken at the Massachusetts General Hospital and was governed by the Institutional Review Board (IRB: 2020P000263) all patients agreed to participation via informed written consent prior to enrollment in the study. RESULTS A total of 108 patients were enrolled in the study of which 94 underwent successful revascularization procedures. Of those 94 patients, 38 (40.4%) underwent open bypass, 39 (41.5%) underwent endovascular revascularization, and 17 (18.1%) underwent a hybrid approach. There were no significant differences in post-operative outcomes between operative approaches. Twenty-five patients (28.7%) experienced major revascularization complications as defined as re-occlusion of the treated vessel/thrombosis of the bypass graft (n = 13) or development of post-operative infection (n = 12). There was no significant difference in median income ($75,295 vs $87,757, p = NS), distance lived from hospital, (27.4 miles vs. 29.7 miles, p = NS), or type of insurance (private 24% vs 26%, government 76% vs 73%, p = NS between patients that experienced complications versus those that did not have complications. These findings suggest the risk of major graft failure is independent of a patient's socioeconomic status, distance lived from hospital, or insurance type in patients undergoing revascularization procedures for PAD. CONCLUSION While socioeconomic factors impact access to and have a known association with negative outcomes, complications in patients with PAD appear to be independent of these factors. To mitigate the negative outcomes in patients with peripheral artery disease, a focus should be on patient risk factors and modifiable medical factors that contribute to adverse outcomes.

Abstract
BACKGROUND The American Heart Association (AHA), in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, nutrition, sleep, and obesity) and health factors (cholesterol, blood pressure, glucose control, and metabolic syndrome) that contribute to cardiovascular health. The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs). METHODS The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing. The 2024 AHA Statistical Update is the product of a full year's worth of effort in 2023 by dedicated volunteer clinicians and scientists, committed government professionals, and AHA staff members. The AHA strives to further understand and help heal health problems inflicted by structural racism, a public health crisis that can significantly damage physical and mental health and perpetuate disparities in access to health care, education, income, housing, and several other factors vital to healthy lives. This year's edition includes additional global data, as well as data on the monitoring and benefits of cardiovascular health in the population, with an enhanced focus on health equity across several key domains. RESULTS Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics. CONCLUSIONS The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Abstract
OBJECTIVE Given the ongoing nature of research in the social determinants space and urges to improve United States Preventive Services Task Force screening efforts for abdominal aortic aneurysms (AAAs), this project aims to characterize the association between the level of socioeconomic deprivation, rurality, and ruptured AAA (rAAA) presentation across the United States. METHODS We queried the Vascular Quality Initiative registry (2010-2019) for patients with AAAs. The area deprivation index (ADI) is an index from 1 to 100 used to capture socioeconomic status. ADI was grouped into quintiles, with the most deprived regions being quintile 5 and having the highest ADI index. Multivariable logistic regression assessed the association between ADI, rurality, and rAAA presentation overall and before age 65. RESULTS Of the 82,909 patients included, 11,458 patients (14%) resided in the most socioeconomically deprived regions, and 18,083 patients (22%) lived in rural regions. Overall, 6831 patients (8.2%) experienced an rAAA, with 4696 patients (69%) residing in the three most deprived quintiles. Most patients underwent endovascular repair (n = 67,933; 82%), followed by open repair (n = 14,976; 18%). On multivariable analysis, residence in the most socioeconomically deprived region was associated with a near 1.5-fold increased odds of presenting with an rAAA compared with a residence in the least deprived regions (odds ratio [OR], 1.46; 95% confidence interval [CI], 1.31-1.63; P < .001), whereas urban residence was associated with a decreased odds to present with an rAAA compared with rural residence (OR, 0.84; 95% CI, 0.79-0.89; P < .001). When stratifying the study population by the United States Preventive Services Task Force recommended age for AAA screening (65 years old), 14,147 patients (17%) were under 65. Of those under 65, 1381 patients (9.8%) experienced a rAAA, and 9955 patients (71%) resided in the three most deprived quintiles. Residence in the most socioeconomically deprived region was associated with an increased odds of presenting with an rAAA compared with residence in the least deprived region (OR, 1.31; 95% CI, 1.01-1.69; P = .042). However, there were no significant associations between rural residence and increased rAAA presentation among individuals under 65 (OR, 1.07; 95% CI, 0.93-1.23; P = .36). CONCLUSIONS Among all patients in this study, patients residing in highly socioeconomically deprived or rural regions were more likely to present with an rAAA, but among those under 65, only residence in a socioeconomically deprived area was associated with increased odds of rAAA presentation. Understanding the effects of socioeconomic deprivation on rAAA presentation can identify at-risk populations for early AAA screening before rupture.

Abstract
OBJECTIVE Readmission after vascular procedures is a burden to hospitals and the Medicare system. Therefore, identifying risk factors leading to readmission is vital. We examined the frequency of and risk factors for 30-day readmission after open aneurysm repair (OAR) and explored post-operative outcomes with special attention for those with preexisting chronic kidney disease (CKD). METHODS Patients who underwent OAR were identified in the National Readmission Database (2016-2018). Demographic information and comorbidities were collected. Patients readmitted within 30 days after their index hospitalization were identified and compared to patients without readmission records. RESULTS A total of 5090 patients underwent OAR during the study timeframe with 488 patients (9.6%) were readmitted within 30 days. Females were more readmitted than males (F = 11.1% vs M = 9.0%, P < 0.001). Readmitted patients had more comorbidities (median ECI 12, P < 0.05), were on Medicare (73.7%, P < 0.001), had higher surgery admission cost ($146,844, P < 0.001), longer length of stay (8 days, P < 0.001), and were discharged to a lower level care facility (62.7%, P < 0.001). Comorbidities that predisposed patients for readmission include: peripheral arterial disease (OR 2.15, P < 0.01), asthma (OR 1.87, P < 0.01), chronic heart failure (OR 1.74, P < 0.05). On readmission visit, acute renal failure (23.8%) was the most common diagnosis, while intestinal surgery (13.7%) was the most common procedure. Patients with CKD (n = 968, 18.9% of total population) had double the mortality rate compared to non-CKD patients on surgery admission (10.4%, P < 0.001) and readmission (10.1%, P < 0.001). CONCLUSION Certain factors were noted to increase readmission rate, special attention need to be paid when dealing with such group of patients requiring OAR. Vascular surgeons should meticulously weigh benefits and risks when considering OAR in patients with CKD who are not a candidate for endovascular repair, and optimize their kidney function before considering such approach.

Patients from distressed communities are more likely to be symptomatic at endovascular aneurysm repair and have an increased risk of being lost to long-term follow-up. J Vasc Surg 2023; 77:1087-1098.e3. [PMID: 36343872 DOI: 10.1016/j.jvs.2022.10.053] [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: 06/24/2022] [Revised: 10/17/2022] [Accepted: 10/25/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND Endovascular aortic aneurysm repair (EVAR) has become the preferred modality to repair abdominal aortic aneurysms (AAAs). However, the effect of the distressed communities index (DCI) on the outcomes of EVAR is still unknown. In the present study, we investigated the effect of DCI on the postoperative outcomes after EVAR. METHODS The Society for Vascular Surgery Vascular Quality Initiative database was used for the present study. Patients who had undergone EVAR from 2003 to 2021 were selected for analysis. The study cohort was divided into two groups according to their DCI score. Patients with DCI scores ranging from 61 to 100 were assigned to group I (DCI >60), and those with DCI scores ranging from 0 to 60 were assigned to group II (DCI ≤60). The primary outcomes included the 30-day and 1-year mortality and major adverse cardiovascular events at 30 days. Regression analyses were performed to study the postoperative outcomes. P values ≤ .05 were deemed statistically significant for all analyses in the present study. RESULTS A total of 60,972 patients (19.5% female; 80.5% male) had undergone EVAR from 2003 to 2021. Of these patients, 18,549 were in group I (30.4%) and 42,423 in group II (69.6%). The mean age of the study cohort was 73 ± 8.9 years. Group I tended to be younger (mean age, 72.6 vs 73.7 years), underweight (3.5% vs 2.5%), and African American (10.8% vs 3.5%) and were more likely to have Medicaid insurance (3.6% vs 1.9%; P < .05 for all). Group I had had more smokers (87.3% vs 85.3%), a higher rate of comorbidities, including hypertension (84.5% vs 82.9%), diabetes (21.7% vs 19.7%), coronary artery disease (30.3% vs 28.6%), chronic obstructive pulmonary disease (36.9% vs 31.8%), and moderate to severe congestive heart failure (2.6% vs 2%; P < .05 for all). The group I patients were more likely to undergo EVAR for symptomatic AAAs (11.1% vs 7.9%; P < .001; adjusted odds ratio [aOR], 1.25; 95% confidence interval [CI], 1.15-1.37; P < .001) with a higher risk of mortality at 30 days (aOR, 3.98; 95% CI, 2.23-5.44; P < .001) and 1 year (aOR, 1.74; 95% CI, 1.43-2.13; P < .001). A higher risk of being lost to follow-up (28.9% vs 26.3%; P < .001) was also observed in group I. CONCLUSIONS Patients from distressed communities who require EVAR tended to have multiple comorbidities. These patients were also more likely to be treated for symptomatic AAAs, with a higher risk of mortality. An increased incidence of lost to long-term follow-up was also observed for this population. Surgeons and healthcare systems should consider these outcomes and institute patient-centered approaches to ensure equitable healthcare.

Abstract
OBJECTIVE In the present study, we used a national database to identify racial differences in the presentation and outcomes for patients undergoing endovascular abdominal aortic aneurysm (AAA) repair (EVAR) and identified areas for improving their care. METHODS We queried the EVAR-targeted National Surgical Quality Improvement Program database (2016-2019) to identify patients who had undergone EVAR for both ruptured and nonruptured AAAs. The patients were categorized according to race (White, Black, and Asian). Patients with a history of abdominal aortic surgery or an indication other than AAAs were excluded. The data was analyzed using the χ2 and Kruskal-Wallis tests, presented as frequencies and percentages or median and interquartile range (IQR) for categorical and continuous variables, respectively. RESULTS We identified 3629 patients (16.6% female), including 3312 White (91.3%), 248 Black (6.8%), and 69 Asian (1.9%) patients. Black patients were more frequently women (27.0%) compared with White patients (15.9%) and were younger (median age, 71 years; IQR, 64-77 years) than White (median age, 73 years; IQR, 67-79 years) and Asian (median age, 76 years; IQR, 67-81 years) patients (P < .001 for both). The incidence of smoking, congestive heart failure, and dialysis dependency was highest for Black patients, and the incidence of obesity was lowest for Asian patients. The AAAs in Black patients extended more frequently beyond the aortic bifurcation (P = .047). In Asian patients, the internal iliac arteries were more involved (P = .040). For Black patients, 29.8% of the EVARs were performed in a nonelective setting compared with 20.2% for the White and 15.9% for the Asian patients (P < .001). The aneurysm diameter, nonruptured symptomatic rate, and rupture rate were similar across the groups (P = .807). The operative time was prolonged for Black (median, 128 minutes; IQR, 96-177 minutes) compared with White (median, 114 minutes; IQR, 84-162 minutes) patients (P < .001). Postoperatively, Black patients were more likely to require blood transfusion (16.5%) and had prolonged length of hospital stay (median, 2 days; IQR, 1-4 days) compared with White (10.0%; median, 1 day; IQR, 1-3 days) and Asian (4.3%; median, 1 day; IQR, 1-3 days) patients (P = .001 and P < .001, respectively). Black patients also had a higher 30-day readmission rate (P = .038). On multivariate analysis, Black race was an independent factor for length of stay >1 day after both elective and nonelective EVAR and 30-day readmission for elective EVAR, but not 30-day mortality after elective and nonelective EVAR. CONCLUSIONS In the present nationwide sample of EVAR cases, Black patients were more often women and younger. Despite similar rates of symptomatic and ruptured AAAs at presentation and 30-day mortality, Black patients more often presented and were treated during the same nonelective admission; they also had associated increased length of hospital stay and readmission. These findings signal a missed opportunity to diagnose, optimize, and treat this particular group of patients in an elective setting.

Maheswaran R, Tong T, Michaels J, Brindley P, Walters S, Nawaz S. Socioeconomic disparities in abdominal aortic aneurysm repair rates and survival. Br J Surg 2022; 109:958-967. [PMID: 35950728 PMCID: PMC10364757 DOI: 10.1093/bjs/znac222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 05/23/2022] [Accepted: 05/29/2022] [Indexed: 08/02/2023]
Abstract
BACKGROUND Abdominal aortic aneurysm (AAA) is more prevalent in socioeconomically disadvantaged areas. This study investigated socioeconomic disparities in AAA repair rates and survival. METHODS The study used ecological and cohort study designs, from 31 672 census areas in England (April 2006 to March 2018), the Index of Multiple Deprivation 2010 as the area-level deprivation indicator, and Poisson, logistic and Cox regression. RESULTS Some 77 606 patients (83.4 per cent men) in four age categories (55-64, 65-74, 75-84, 85 or more years) were admitted with AAA from a population aged at least 55 years of 14.7 million. Elective open and endovascular repair rates were 41 (95 per cent c.i. 23 to 61) and 60 (36 to 89) per cent higher respectively among men aged 55-64 years in the most versus least deprived areas by quintile. This differences diminished and appeared to reverse with increasing age, with 26 (-1 to 45) and 25 (13 to 35) per cent lower rates respectively in men aged 85 years or more in the most deprived areas. Men admitted from more deprived areas were more likely to die in hospital without aneurysm repair. Among those who had aneurysm repair, this was more likely to be for a ruptured aneurysm than among men from less deprived areas. For intact aneurysm repair, they were relatively more likely to have this during an emergency admission. The mortality rate after repair was higher for men from more deprived areas, although the hazard diminished with age. Patterns were unclear for women. CONCLUSION There were clear socioeconomic disparities in operation rates, mode of presentation, and outcome for AAA surgery. Policies are needed to address these disparities.

Abstract
BACKGROUND The American Heart Association, in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, diet, and weight) and health factors (cholesterol, blood pressure, and glucose control) that contribute to cardiovascular health. The Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, congenital heart disease, rhythm disorders, subclinical atherosclerosis, coronary heart disease, heart failure, valvular disease, venous disease, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs). METHODS The American Heart Association, through its Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States to provide the most current information available in the annual Statistical Update. The 2022 Statistical Update is the product of a full year's worth of effort by dedicated volunteer clinicians and scientists, committed government professionals, and American Heart Association staff members. This year's edition includes data on the monitoring and benefits of cardiovascular health in the population and an enhanced focus on social determinants of health, adverse pregnancy outcomes, vascular contributions to brain health, and the global burden of cardiovascular disease and healthy life expectancy. RESULTS Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics. CONCLUSIONS The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Abstract
Despite declining incidence and mortality rates in many countries, the abdominal aortic aneurysm (AAA) continues to represent a life-threatening cardiovascular condition with an overall prevalence of about 2-3% in the industrialized world. While the risk of AAA development is considerably higher for men of advanced age with a history of smoking, screening programs serve to detect the often asymptomatic condition and prevent aortic rupture with an associated death rate of up to 80%. This review summarizes the current knowledge on identified risk factors, the multifactorial process of pathogenesis, as well as the latest advances in medical treatment and surgical repair to provide a perspective for AAA management.

Abstract
Background The clinical impact of the distressed communities index (DCI), a composite measure of economic well-being based on the U.S. zip code, is becoming increasingly recognized. Ranging from 0 (prosperous) to 100 (distressed), DCI's association with cardiovascular outcomes remains unknown. We aimed to study the association of the DCI with presentation and outcomes in adults with severe symptomatic aortic stenosis (AS) undergoing transcatheter aortic valve intervention (TAVR) in an affluent county in New York. Methods The study population included 286 patients with severe symptomatic AS or degeneration of a bioprosthetic valve who underwent TAVR with a newer generation transcatheter heart valve (THV) from December 2015 to June 2018 at an academic tertiary medical center. DCI for each patient was derived from their primary residence zip code. Patients were classified into DCI deciles and then categorized into 4 groups. The primary and secondary outcomes of interest were 30-day, 1-year, and 3-year mortality, respectively. Results Among 286 patients studied, 26%, 28%, 28%, and 18% were categorized into DCI groups 1–4, respectively (DCI <10: n = 73; DCI 10–20: n = 81; DCI 20–30: n = 80; DCI >30: n = 52). Patients in group 4 were younger with worse kidney function compared to patients in groups 1 and 2. They also had smaller aortic annuli and were more likely to receive a smaller THV. No significant difference in hospital length of stay or distribution of in-hospital, 30-day, 1-year, and 3-year mortality was demonstrated. Conclusions While the DCI was associated with differences in the clinical and anatomic profile, it was not associated with differences in clinical outcomes in this prospective observational study of adults undergoing TAVR suggesting that access to care is the likely discriminator.

Incidence and predictors of early and delayed renal function decline after aortic aneurysm repair in the Vascular Quality Initiative database. J Vasc Surg 2021; 74:1537-1547.

Abstract
BACKGROUND Postoperative acute kidney injury (AKI) may complicate both open and endovascular aortic aneurysm repair (EVAR) and is associated with substantial morbidity, mortality, and health care expense. We aim to evaluate the incidence of postoperative AKI and factors associated with its occurrence and the effects of postoperative AKI on long-term renal function and mortality after open and EVAR in the Society for Vascular Surgery Vascular Quality Initiative registry. METHODS Elective aneurysm cases were identified including thoracic endovascular aortic aneurysm repair (TEVAR) and complex endovascular aortic aneurysm repair (cEVAR), infrarenal endovascular repair (EVAR) and infrarenal open repair (OAR) from 2003 to 2019. The preoperative estimated glomerular filtration rate (eGFR) was calculated using the Modification of Diet in Renal Disease formula and stratified based on chronic kidney disease (CKD) grades. Postoperative AKI was defined per the Vascular Quality Initiative definition as a creatinine increase of 0.5 mg/dL or if postoperative dialysis was required. Patients on preprocedural hemodialysis and those with previous renal transplant were excluded. Demographics and procedural factors were evaluated for predicting in-hospital postoperative AKI (all approaches) and at 9 to 21 months of long-term follow-up (EVAR only) using logistic regression modeling. RESULTS We identified a total of 2813 cEVAR, 2995 TEVAR, 39,945 EVAR, and 8143 OAR patients. Of those, postoperative AKI occurred in 377 cEVAR (13.5%), 199 TEVAR (6.7%), 1099 EVAR (2.8%), and 1249 OAR (15.5%). Risk factors for postoperative AKI across all groups were worse preoperative eGFR, total number of blood transfusions, perioperative anemia, reinterventions, and postoperative respiratory complications. Additional procedure-specific risk factors of postoperative AKI were preoperative hemoglobin of less than 10 and contrast volume of 125 to 150 mL, hypertension, a low ejection fraction, and a history of percutaneous revascularization for EVAR; for both EVAR/cEVAR, renal artery coverage was a risk factor, whereas for OAR, male sex, non-White race, hypertension, suprarenal aortic cross-clamp, and increased renal ischemic time were risk factors. Among 8133 EVAR patients with long-term follow-up, a decrease in kidney function occurred in 56.7% of patients with postoperative AKI vs 19.9% without postoperative AKI (P < .001). The following risk factors were associated with a decrease in renal function at long-term follow-up: postoperative AKI, a preoperative eGFR of less than 90, and hypertension. A preoperative hemoglobin of greater than 12 was protective. Postoperative AKI was associated with significantly lower survival compared with no postoperative AKI across all procedures (log rank <0.001). CONCLUSIONS Postoperative AKI occurs more often in patients with worse preoperative renal function, lower preoperative hemoglobin, and in open surgeries with inter-renal or suprarenal cross-clamping. Importantly, postoperative AKI is associated with increased mortality across all types of aortic repair. Given the long-term impact of postoperative AKI on outcomes for all aortic repairs and the limitations of current insensitive functional indices, there is a need to seek more sensitive indicators of decreases in early renal structural in this population.

Abstract
OBJECTIVE The objective of this study was to determine differences in mortality after abdominal aortic aneurysm (AAA) repair based on insurance type. METHODS In this retrospective cohort study, data from all-payer patients in nonpsychiatric hospitals in New York, Maryland, Florida, Kentucky, and California from January 2007 to December 2014 (excluding California, ending December 2011) were extracted from the State Inpatient Databases, Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality. There were 90,102 patients ≥18 years old with available insurance data who underwent open AAA repair or endovascular aneurysm repair (EVAR) identified using International Classification of Diseases, Ninth Revision, Clinical Modification procedure codes 3844, 3925, and 3971. EVAR patients were identified using the procedure code 3971, and the remainder of cases were categorized as open. Patients were divided into cohorts by insurance type as Medicare, Medicaid, uninsured (self-pay/no charge), other, or private insurance. Patients were further stratified for subgroup analyses by procedure type. Unadjusted rates of in-hospital mortality, the primary outcome, as well as secondary outcomes, such as surgical urgency, 30-day and 90-day readmissions, length of stay, total charges, and postoperative complications, were examined by insurance type. Adjusted odds ratios (ORs) for in-hospital mortality were calculated using multivariate logistic regression models fitted to the data. The multivariate models included patient-, surgical-, and hospital-specific factors with bivariate baseline testing suggestive of association with insurance status in addition to variables that were selected a priori. RESULTS Medicaid and uninsured patients had the highest rates of mortality relative to private insurance beneficiaries in all cohorts. Medicaid patients incurred a 47% increase in the odds of mortality, the highest among the insured, after all AAA repairs (OR, 1.47; 95% confidence interval [CI], 1.23-1.76), whereas uninsured patients experienced a 102% increase in the odds of mortality (OR, 2.02; 95% CI, 1.54-2.67). Subgroup analyses for open AAA repair and EVAR corroborated that Medicaid insurance (open repair OR, 1.37 [95% CI, 1.14-1.64]; EVAR OR, 2.06 [95% CI, 1.40-3.04]) and uninsured status (open repair OR, 1.85 [95% CI, 1.35-2.54]; EVAR OR, 2.96 [95% CI, 1.82-4.81]) were associated with the highest odds of mortality after both procedures separately. CONCLUSIONS This study demonstrates that Medicaid insurance and uninsured status are associated with higher unadjusted rates and adjusted ORs for in-hospital mortality after AAA repair relative to private insurance status. Primary payer status therefore serves as an independent predictor of the risk of death subsequent to AAA surgical interventions.
