This study sought to characterize the current US experience of aortic prosthetic valve endocarditis (PVE) compared with native valve endocarditis (NVE).The Society of Thoracic Surgeons Database was queried for entries of active aortic infective endocarditis (IE). Two analyses were performed: (1) trends of surgical volume and operative mortality (2011-2019); and (2) descriptive and risk-adjusted comparisons between PVE and NVE (2014-2019) using multivariable logistic regression.From 2011 to 2019, there was a yearly increase in the proportion of PVE (20.9% to 25.9%; P.001) with a concurrent decrease in operative mortality (PVE, 22.5% to 10.4%; P.001; NVE, 10.9% to 8.5%; P.001). From 2014 to 2019, active aortic IE was identified in 9768 patients (NVE, 6842; PVE, 2926). Aortic root abscess (50.1% vs 25.2%; P.001), aortic root replacement (50.1% vs 12.8%; P.001), homograft implantation (27.2% vs 4.1%; P.001), and operative mortality (12.2% vs 6.4%; P.001) were higher in PVE. After risk adjustment, PVE (odds ratio [OR], 1.5; 95% CI,1.16-1.94; P.01), aortic root replacement (OR, 1.49; 95% CI,1.15-1.92; P.001), Staphylococcus aureus (OR, 1.5; 95% CI,1.23-1.82; P.001), and unplanned revascularization (OR, 5.83; 95% CI,4.12-8.23; P.001) or mitral valve surgery (OR, 2.29; 95% CI,1.5-3.51; P.001) correlated with a higher operative mortality, whereas prosthesis type (P = .68) was not an independent predictor.IE in the United States has risen over the past decade. However, operative mortality has decreased for both PVE and NVE. PVE, extension of IE requiring aortic root replacement, and additional unplanned surgical interventions carry an elevated mortality risk. Prosthesis selection did not affect operative mortality.

Conversion to thoracotomy during minimally invasive lobectomy for lung cancer is occasionally necessary. Differences between video-assisted thoracoscopic surgery (VATS) and robotic-assisted thoracoscopic surgery (RATS) lobectomy conversion have not been described.We queried The Society of Thoracic Surgeons General Thoracic Surgery Database from January 1, 2015 to December 31, 2018. Patients with prior thoracic operations and metastatic disease were excluded. Univariable comparisons with χThere were 27,695 minimally invasive lobectomies from 269 centers. Conversion to thoracotomy occurred in 11.0% of VATS and 6.0% of RATS (P.001). Conversion was associated with increased mortality (P.001), major complications (P.001), and intraoperative (P.001) and postoperative (P.001) blood transfusions. Conversion from RATS occurred emergently (P.001) and for vascular injury (P.001) more frequently than from VATS, but there was no difference in overall major complications or mortality. Mortality after conversion was 3.1% for RATS and 2.2% for VATS (P = .24). Clinical cancer stage II or III (P.001), preoperative chemotherapy (P = .003), forced expiratory volume in 1 second (P = .006), body mass index (P.001), and left-sided resection (P = .0002) independently predicted VATS conversion. For RATS clinical stage III (P = .037), left-sided resection (P = .041), and forced expiratory volume in 1 second (P = .002) predicted conversion. Lower volume centers had increased rates of conversion (P.001) in both groups.Conversion from minimally invasive to open lobectomy is associated with increased morbidity and mortality. Conversion occurs more frequently during VATS compared with RATS, albeit less often emergently, and with similar rates of overall mortality and major complications. Predictors, urgency, and reasons for conversion differ between RATS and VATS lobectomy and may assist in patient selection.

For the more than 40,000 children in the United States undergoing congenital heart surgery annually, the relationship between hospital quality and costs remains unclear. Prior studies report conflicting results and clinical outcomes have continued to improve over time. We examined a large contemporary cohort, aiming to better inform ongoing initiatives seeking to optimize health care value in this population.Clinical information (The Society of Thoracic Surgeons Congenital Database) was merged with standardized cost data (Pediatric Health Information Systems) for children undergoing heart surgery from 2010 to 2015. In-hospital cost variability was analyzed using Bayesian hierarchical models adjusted for case-mix. Quality metrics examined included in-hospital mortality, postoperative complications, postoperative length of stay (PLOS), and a composite.Overall, 32 hospitals (n = 45,315 patients) were included. Median adjusted cost per case varied across hospitals from $67,700 to $51,200 in the high vs low cost tertile (ratio 1.32; 95% credible interval, 1.29 to 1.35), and all quality metrics also varied across hospitals. Across cost tertiles, there were no significant differences in the quality metrics examined, with the exception of PLOS. The PLOS findings were driven by high-risk The Society of Thoracic Surgeons-European Association for Cardiothoracic Surgery categories 4 and 5 cases (adjusted median length of stay 16.8 vs 14.9 days in high vs low cost tertile [ratio 1.13, 1.05 to 1.24]), and intensive care unit PLOS.Contemporary congenital heart surgery costs vary across hospitals but were not associated with most quality metrics examined, highlighting that performance in one area does not necessarily convey to others. Cost variability was associated with PLOS, particularly related to intensive care unit PLOS and high-risk cases. Care processes influencing PLOS may provide targets for value-based initiatives in this population.

ObjectiveTo compare maternal obstetric complications and nonelective readmissions in women with common neurologic comorbidities (WWN) vs women without neurologic disorders.MethodsWe performed a retrospective cohort study of index characteristics and acute postpartum, nonelective rehospitalizations from the 2015–2017 National Readmissions Database using ICD-10 codes. Wald χ2 testing compared baseline demographic, hospital, and clinical characteristics and postpartum complications between WWN (including previous stroke, migraine, multiple sclerosis [MS], and myasthenia gravis [MG]) and controls. Multivariable logistic regression models examined odds of postpartum complications and nonelective readmissions within 30 and 90 days for each neurologic comorbidity compared to controls (α = 0.05).ResultsA total of 7,612 women with previous stroke, 83,430 women with migraine, 6,760 women with MS, 843 women with MG, and 8,136,335 controls met the criteria for index admission after viable infant delivery. WWN were more likely than controls to have inpatient diagnoses of edema, proteinuria, or hypertensive disorders and to have received maternal care for poor fetal growth. The adjusted odds of a Centers for Disease Control and Prevention severe maternal morbidity indicator were greater for women with previous stroke (adjusted odds ratio [AOR] 8.53, 95% CI 7.24–10.06), migraine (AOR 2.04, 95% CI 1.85–2.26), and MG (AOR 4.45, 95% CI 2.45–8.08) (all p < 0.0001). Readmission rates at 30 and 90 days for WWN were higher than for controls (30 days: previous stroke 2.9%, migraine 1.7%, MS 1.8%, MG 4.3%, controls 1.1%; 90 days: previous stroke 3.7%, migraine 2.5%, MS 5.1%, MG 6.0%, controls 1.6%). Women with MG had the highest adjusted odds of readmission (30 days: AOR 3.96, 95% CI 2.37–6.65, p < 0.0001; 90 days: AOR 3.30, 95% CI 1.88–5.78, p < 0.0001).DiscussionWWN may be at higher risk of severe maternal morbidity at the time of index delivery and postpartum readmission. More real-world evidence is needed to develop research infrastructure and create efficacious interventions to optimize maternal–fetal outcomes in WWN, especially for women with previous stroke or MG.

Background The Society of Thoracic Surgeons (STS) Quality Measurement Task Force has developed risk models and composite performance measures for isolated coronary artery bypass grafting (CABG), isolated aortic valve replacement (AVR), isolated mitral valve replacement or repair (MVRR), AVR+CABG, and MVRR+CABG. To further enhance its portfolio of risk-adjusted performance metrics, STS has developed new risk models for multiple valve operations ± CABG procedures. Methods Using July 2011 to June 2019 STS Adult Cardiac Surgery Database data, risk models for AVR+MVRR (n = 31,968) and AVR+MVRR+CABG (n = 12,650) were developed with the following endpoints: Operative Mortality, major morbidity (any 1 or more of the following: cardiac reoperation, deep sternal wound infection/mediastinitis, stroke, prolonged ventilation, and renal failure), and combined mortality and/or major morbidity. Data were divided into development (July 2011 to June 2017; n = 35,109) and validation (July 2017 to June 2019; n = 9509) samples. Predictors were selected by assessing model performance and clinical face validity of full and progressively more parsimonious models. Performance of the resulting models was evaluated by assessing discrimination and calibration. Results C-statistics for the overall population of multiple valve ± CABG procedures were 0.7086, 0.6734, and 0.6840 for mortality, morbidity, and combined mortality and/or morbidity in the development sample, and 0.6953, 0.6561, and 0.6634 for the same outcomes, respectively, in the validation sample. Conclusions New STS Adult Cardiac Surgery Database risk models have been developed for multiple valve ± CABG operations, and these models will be used in subsequent STS performance metrics.

Certain neurologic diseases have been noted to vary by season, and this is important for understanding disease mechanisms and risk factors, but seasonality has not been systematically examined across the spectrum of neurologic disease, and methodologic guidance is also lacking.Using nationally representative data from the National Inpatient Sample, a stratified 20% sample of all non-federal acute care hospitalizations in the United States, we calculated the monthly rate of hospitalization for 14 neurologic diseases from 2016 to 2018. For each disease, we assessed seasonality of hospitalization using chi-squared, Edward, and Walter-Elwood tests and seasonal time series regression models. Statistical tests were adjusted for multiple hypothesis testing using Bonferroni correction.Meningitis, encephalitis, ischemic stroke, intracerebral hemorrhage, Guillain-Barre syndrome, and multiple sclerosis had statistically significant seasonality according to multiple methods of testing. Subarachnoid hemorrhage, status epilepticus, myasthenia gravis, and epilepsy had significant seasonality according to Edwards and Walter-Elwood tests but not chi-square tests. Seasonal time series regression illustrated seasonal variation in all 14 diseases of interest, but statistical testing for seasonality within these models using the Kruskal-Wallis test only achieved statistical significance for meningitis.Seasonal variation is present across the spectrum of acute neurologic disease, including some conditions for which seasonality has not previously been described, and can be examined using multiple different methods.

Objective:We sought to determine who is involved in the care of a trauma patient.Methods:We recorded hospital personnel involved in 24 adult Priority 1 trauma patient admissions for 12 h or until patient demise. Hospital personnel were delineated by professional background and role.Results:We cataloged 19 males and 5 females with a median age of 50-y-old (interquartile range [IQR], 35.5-67.5). The average number of hospital personnel involved was 79.71 (standard deviation, 17.62; standard error 3.6). A median of 51.2% (IQR, 43.4%-59.8%) of personnel were first involved within hour 1. More personnel were involved in direct versus indirect care (median 54.5 [IQR, 47.5-67.0] vs 25.0 [IQR, 22.0-30.5];P< 0.0001). Median number of health-care professionals and auxiliary staff were 74.5 (IQR, 63.5-90.5) and 6.0 (IQR, 5.0-7.0), respectively. More personnel were first involved in hospital locations external to the emergency department (median, 53.0 [IQR, 41.5-63.0] vs 27.5 [IQR, 24.0-30.0];P< 0.0001). No differences existed in total personnel by Injury Severity Score (P= 0.1266), day (P= 0.7270), or time of admission (P= 0.2098).Conclusions:A large number of hospital personnel with varying job responsibilities respond to severe trauma. These data may guide hospital staffing and disaster preparedness policies.

Previous single-center studies of diaphragm paralysis (DP) after pediatric cardiac surgery report incidence of 0.3% to 12.8% and associate DP with respiratory complications, prolonged ventilation and length of stay, and mortality. To better define incidence and associations between DP and various procedures and outcomes, we performed a multicenter study.The Society of Thoracic Surgeons Congenital Heart Surgery Database was queried to identify children who experienced DP after cardiac surgery (2010-2018; 126 centers). Baseline characteristics and postoperative outcomes were compared between patients with and without DP as well as between patients who underwent plication and those who did not. Associations between center volume and center rates of DP and use of plication were also explored.A total of 2214 of 191,463 (1.2%) patients experienced DP. Postoperative DP portended worse outcomes, including mortality (5.6% vs 3.5%; P.001), major morbidity (37.2% vs 10.7%; P.001), tracheostomy (7.1% vs 0.9%; P.001), prolonged mechanical ventilation (38.0% vs 7.8%; P.001), and 30-day readmission (22.0% vs 10.6%; P.001). A total of 1105 of 2214 (49.9%) patients with DP underwent plication. Patients who underwent plication were younger, were smaller, had more risk factors, and underwent more complex surgeries. Plication rates varied widely across centers. There was no correlation between center volume and center risk-adjusted rates of DP (r = .05, P = .5), nor frequency of plication (r = .08, P = .4).DP complicating pediatric heart surgery is rare but portends significantly worse outcomes. One-half of patients underwent plication. Center-level risk-adjusted rates of DP and plication are not associated with case volume. Significant variability in plication practices suggests a target for quality improvement.

Background There are no criteria to estimate the risk of early discharge after anatomic lung resection. We hypothesized that demographic, clinical, and surgical variables could be used to predict successful postoperative day 1 (POD1) discharge after anatomic lung resection. Methods Patients with POD1 discharge after anatomic lung resection were identified in The Society of Thoracic Surgeons database from 2012 to 2018. Discharges were categorized as successful based on freedom from complications, readmission, or death. A multivariable model identified variables from univariate analysis and was further optimized using stepwise selection. This model was used to create a risk score of success. Results Among 62,785 patients who underwent anatomic lung resection, 2480 (3.9%) were discharged on POD1. Of the 2480 patients, 2129 (85.8%) had successful discharge and 351 (14.2%) had failed discharge due to postoperative complication (282; 11.3%), readmission (151; 6.1%), or death (9; 0.4%). In univariable analysis, successful POD1 discharge was associated with younger age, female sex, video-assisted thoracic surgery, higher forced expiratory volume in 1 second and diffusion capacity of lung for carbon monoxide, shorter operating room times, and lower rates of comorbidities. A risk model for successful discharge incorporated sex, age, body mass index, operative lobe, Zubrod score, American Society of Anesthesiologists class, coronary artery disease, chronic obstructive pulmonary disease, video-assisted thoracic surgery approach, and operating room time. Using this model, a risk score created, and derived estimated proportion of successful POD1 discharge varied from 75.6% to 92.9%. Conclusions Demographic, clinical, and surgical variables are associated with successful POD1 discharge. This analysis suggests that a combination of demographic factors is associated with failed early discharge, and this understanding can be used in conjunction with clinical judgment to facilitate decisions regarding appropriateness of POD1 discharge.

There are conflicting reports in the literature comparing outcomes after open Ravitch and minimally invasive Nuss procedures for pectus excavatum repair, and there is relatively little data available comparing the outcomes of these procedures performed by thoracic surgeons.The 2010 to 2018 Society of Thoracic Surgeons General Thoracic Surgery Database was queried for patients age 12 or greater undergoing open or minimally invasive repair of pectus excavatum. Patients were stratified by operative approach. Multivariable logistic regression was performed with a composite outcome of 30-day complications.A total of 1,767 patients met inclusion criteria, including 1,017 and 750 patients who underwent minimally invasive pectus repair and open repair, respectively. Open repair patients were more likely to be American Society of Anesthesiologists (ASA) class III or greater (24% vs 14%; P.001), have a history of prior cardiothoracic surgery (26% vs 14%; P.001), and require longer operations (median 268 vs 185 minutes; P.001). Open repair patients were more likely to require greater than 6 days of hospitalization (18% vs 7%; P.001), undergo transfusion (7% vs 2%; P.001), and be readmitted (8% vs 5%; P = .004). After adjustment, open repair was not associated with an increased risk of a composite of postoperative complications (odds ratio 0.99, 95% confidence interval 0.67-1.46). This finding persisted after propensity score matching (odds ratio 1.11, 95% confidence interval 0.74-1.67).Pectus excavatum repair procedure type was not associated with the risk of postoperative complications after adjustment. Further investigation is necessary to determine the impact of pectus excavatum repair type on recurrence and patient reported outcomes, including satisfaction, quality of life, and pain control.

Background Extracorporeal membrane oxygenation (ECMO) has been used increasingly for cardiopulmonary rescue. Despite recent advances however, post-cardiotomy shock (PCS)-ECMO survival remains comparatively poor. We sought to evaluate outcomes and define factors that predict in-hospital mortality. Methods We used the Nationwide Inpatient Sample (NIS) to evaluate adult hospitalizations with a primary procedure code for coronary artery bypass grafting (CABG), and/or valve procedures performed between 2013 and 2018, which also required post cardiotomy ECMO support. Patient-related factors and hospital costs were evaluated to identify those associated with in-hospital mortality. Results There were 1,247,835 admissions for cardiac surgical procedures during the study period. Post-cardiotomy shock-ECMO support was provided in 4475 (0.3%) within the study cohort. A total of 2000 (44.7%) hospitalizations involved isolated valvular procedures, 1700 (38.0%) isolated CABG, and 775 (17.3%) involved a combination of both. Overall, in-hospital mortality was 42.1% ( n = 1880). Factors significantly associated with in-hospital mortality included patients with multiple comorbidities (> 7) and those undergoing combination of valve and CABG procedures. Only 26.6% of those who survived to discharge, were discharged home independently. Conclusion Survival to independent home discharge is rare following PCS-ECMO. Its high mortality is associated with multiple comorbidities and combination of CABG and valve surgery.

This study sought to identify the optimal temperature for moderate hypothermic circulatory arrest in patients undergoing elective hemiarch replacement with antegrade brain perfusion.The Society of Thoracic Surgeons adult cardiac surgery database was queried for elective hemiarch replacements using antegrade brain perfusion for aneurysmal disease (2014-2019). Generalized estimating equations and restricted cubic splines were used to determine the risk-adjusted relationships between temperature as a continuous variable and outcomes.Elective hemiarch replacement with antegrade brain perfusion occurred in 3898 patients at 374 centers with a median nadir temperature of 24.9 °C (first quartile, third quartile = 22.0 °C, 27.5 °C) and median circulatory arrest time of 19 minutes (first quartile, third quartile = 14.0 minutes, 27.0 minutes). After adjustment for comorbidities, circulatory arrest time, and individual surgeon, patients cooled between 25 and 28 °C had an early survival advantage compared with 24 °C, whereas those cooled between 21 and 23 °C had higher risks of mortality compared with 24 °C. A nadir temperature of 27 °C was associated with the lowest risk-adjusted odds of mortality (odds ratio, 0.62; 95% confidence interval, 0.42-0.91). A nadir temperature of 21 °C had the highest risk of mortality (odds ratio, 1.4; 95% confidence interval, 1.13-1.73). Risk of experiencing a major morbidity was elevated in patients cooled between 21 and 23 °C, with the highest risk occurring in patients cooled to 21 °C (odds ratio, 1.12; 95% confidence interval, 1.01-1.24).For patients with aneurysmal disease undergoing elective hemiarch with antegrade brain perfusion, circulatory arrest with a nadir temperature of 27 °C confers the greatest early survival benefit and smallest risk of postoperative morbidity.

ImportanceLimited effective therapeutics are available to hospitalized patients with COVID-19. Clinical trials and observational studies have shown varying effects of systemic corticosteroids, including dexamethasone, in hospitalized patients with COVID-19, with limited descriptions of important patient subgroups.ObjectiveTo examine the clinical use of dexamethasone for hospitalized patients with COVID-19 respiratory illness and to explore the heterogeneity of treatment outcomes across different subgroups.Design, Setting, and ParticipantsThis is a retrospective, propensity score–weighted cohort study of adult patients hospitalized for at least 48 hours for COVID-19 respiratory illness between July 1, 2020, and October 31, 2021, at a large health care network of 156 hospitals across the US. Data analysis was performed from March 2022 to February 2023.ExposuresSystemic dexamethasone administered within 48 hours of either admission or escalation in oxygen support.Main Outcomes and MeasuresAll-cause in-hospital mortality or discharge to hospice.ResultsA total of 80 699 patients who met the eligibility criteria were identified (median [IQR] age, 64 [52-76] years; 37 606 women [46.6%]); 13 230 patients (16.4%) identified as Black, 49 222 (60.9%) as White, 18 247 (22.6%) as other race, and 20 340 (25.2%) as Hispanic ethnicity. Of these patients, 13 040 (16.2%) did not require supplemental oxygen within 48 hours of admission, 56 368 (69.8%) required supplemental oxygen, 7618 (9.4%) required noninvasive positive pressure ventilation (NIPPV), and 3673 (4.6%) required mechanical ventilation (MV) and/or extracorporeal membrane oxygenation (ECMO). After adjustment by propensity score overlap weighting, early use of dexamethasone was associated with reduction in a composite outcome of in-hospital mortality or discharge to hospice for patients receiving supplemental oxygen (aOR, 0.92; 95% CI, 0.86-0.98) and MV and/or ECMO (aOR, 0.82; 95% CI, 0.68-0.99). In contrast, all-cause inpatient mortality or discharge to hospice was not lower for patients who received dexamethasone in the no supplemental oxygen group (aOR, 0.90; 95% CI, 0.78-1.03) and in the NIPPV group (aOR, 0.87; 95% CI, 0.73-1.04). Importantly, patients with more comorbidities had greater benefit from dexamethasone use.Conclusions and RelevanceIn this national multicenter cohort study of inpatients with COVID-19, early administration of dexamethasone was associated with significantly reduced odds of mortality or discharge to hospice in those requiring supplemental oxygen or MV and/or ECMO but not in those requiring no supplemental oxygen or NIPPV. These results support the continued use of systemic dexamethasone in patients hospitalized with COVID-19.

Patients on extracorporeal membrane oxygenation (ECMO) who suffer vascular complications frequently accrue additional procedures and costs. We sought to evaluate the effect of ECMO-related vascular complications on hospital charges and in-hospital mortality. Adult discharges involving ECMO from 2004 to 2013 in the National Inpatient Sample were examined. There were 12,636 patients in the cohort. Vascular complications, focusing on arterial complications were identified using ICD-9-CM diagnosis and procedure codes. A multivariable survey linear regression model using median hospital charges was used to model the effect of vascular complications on charges. We used multivariable survey logistic regression to evaluate the effect of vascular complications on in-hospital mortality. Of the 12,636 patients examined, 6467 (51.2%) had ECMO-related vascular complications. Median charges in patients with vascular complications were $ 477,363 (interquartile range: 258,660-875,823) and were $ 282,298 (interquartile range: 130,030-578,027) without vascular complications. On multivariable analysis, patients with vascular complications had 24% higher median charges than patients without vascular complications (Ratio: 1.24; 95% confidence interval [CI]: 1.16-1.33; P0.0001) and 34% higher odds of experiencing in-hospital mortality than patients without vascular complications (adjusted odds ratio: 1.34; 95% CI:1.08-1.66; P = 0.009). Vascular complications occur in over half of ECMO patients and are associated with an increased risk of high hospital charges and in-hospital mortality. These findings support the need for identification and modification of risk factors for ECMO-related vascular complications. Furthermore, the standardization of protocols using evidence-based measures to mitigate vascular complications may improve overall ECMO outcomes.

Recent esophagectomy trends were evaluated to describe the shift in surgical approach and outcomes using the Society of Thoracic Surgeons General Thoracic Surgery Database (STS-GTSD).All patients who underwent an esophagectomy with gastric conduit were identified from 2015-2019 and analyzed according to original intended approach. After performing volume trend analysis of patients, operative outcomes were evaluated.Among 10,607 patients, esophagectomy was open in 5763 (54.3%), minimally-invasive (MIE) in 3524 (33.2%) and robotic (RAMIE) in 1320 (12.4%). Within five years, MIE and RAMIE combined rose to majority approach (open from 58 to 42% of annual volume). While MIE and RAMIE were associated with higher rates of anastomotic leak, loss of conduit, pulmonary embolus, and reoperation, R0 resection and harvested number of lymph nodes exceeded those in open approaches. Operative mortality did not differ by approach (3.21% open vs. 2.72% MIE vs. 2.50% RAMIE; p=0.2329). On multivariable analysis, RAMIE was independently associated with higher rate of anastomotic leak compared to open (aOR 1.53, 95% CI 1.14-2.04), while both MIE and RAMIE had lower mean length of stay. Propensity matching of 1,320 pairs found a higher risk of anastomotic leak requiring surgery for RAMIE compared to MIE (aOR 1.39, 95% CI 1.01-1.92).In less than a decade, the dominant surgical approach in the STS-GTSD has become minimally invasive (RAMIE and MIE). While anastomotic leak and reoperation, more common in RAMIE, require a technical solution, these complications have not raised operative mortality. Further studies are needed to address long-term results and oncologic outcome.

Background: Optimal strategies to improve national congenital heart surgery outcomes and reduce variability across hospitals remain unclear. Many policy and quality improvement efforts have focused primarily on higher-risk patients and mortality alone. Improving our understanding of both morbidity and mortality and current variation across the spectrum of complexity would better inform future efforts. Methods: Hospitals participating in the Society of Thoracic Surgeons Congenital Heart Surgery Database (2014–2017) were included. Case mix–adjusted operative mortality, major complications, and postoperative length of stay were evaluated using Bayesian models. Hospital variation was quantified by the interdecile ratio (IDR, upper versus lower 10%) and 95% credible intervals (CrIs). Stratified analyses were performed by risk group (Society of Thoracic Surgeons–European Association for Cardiothoracic Surgery [STAT] category) and simulations evaluated the potential impact of reductions in variation. Results: A total of 102 hospitals (n=84 407) were included, representing ≈85% of US congenital heart programs. STAT category 1 to 3 (lower risk) operations comprised 74% of cases. All outcomes varied significantly across hospitals: adjusted mortality by 3-fold (upper versus lower decile 5.0% versus 1.6%, IDR 3.1 [95% CrI 2.5–3.7]), mean length of stay by 1.8-fold (19.2 versus 10.5 days, IDR 1.8 [95% CrI 1.8–1.9]), and major complications by >3-fold (23.5% versus 7.0%, IDR 3.4 [95% CrI 3.0–3.8]). The degree of variation was similar or greater for low- versus high-risk cases across outcomes, eg, ≈3-fold mortality variation across hospitals for STAT 1 to 3 (IDR 3.0 [95% CrI 2.1–4.2]) and STAT 4 or 5 (IDR 3.1 [95% CrI 2.4–3.9]) cases. High-volume hospitals had less variability across outcomes and risk categories. Simulations suggested potential reductions in deaths (n=282), major complications (n=1539), and length of stay (101 183 days) over the 4-year study period if all hospitals were to perform at the current median or better, with 37% to 60% of the improvement related to the STAT 1 to 3 (lower risk) group across outcomes. Conclusions: We demonstrate significant hospital variation in morbidity and mortality after congenital heart surgery. Contrary to traditional thinking, a substantial portion of potential improvements that could be realized on a national scale were related to variability among lower-risk cases. These findings suggest modifications to our current approaches to optimize care and outcomes in this population are needed.

OBJECTIVE: Primary amputation (ie, without attempted revascularization) is a devastating complication of peripheral artery disease. Racial disparities in primary amputation have been described; however, rural disparities have not been well investigated. The purpose of this study was to examine the impact of rurality on risk of primary amputation and to explore the effect of race on this relationship. METHODS: The national Vascular Quality Initiative amputation data set was used for analyses (N = 6795). The outcome of interest was primary amputation. Independent variables were race/ethnicity (non-Latinx whites vs nonwhites) and rural residence. Multivariable logistic regression examined impact of rurality and race/ethnicity on primary amputation after adjustment for relevant covariates and included an interaction for race/ethnicity by rural status. RESULTS: Primary amputation occurred in 49% of patients overall (n = 3332), in 47% of rural vs 49% of urban patients (P = .322), and in 46% of whites vs 53% of nonwhites (P < .001). On multivariable analysis, nonwhites had a 21% higher odds of undergoing primary amputation overall (adjusted odds ratio [AOR], 1.21; 95% confidence interval [CI], 1.05-1.39). On subgroup analysis, rural nonwhites had two times higher odds of undergoing primary amputation than rural whites (AOR, 2.06; 95% CI, 1.53-2.78) and a 52% higher odds of undergoing primary amputation than urban nonwhites (AOR, 1.52; 95% CI, 1.19-1.94). In the urban setting, nonwhites had a 21% higher odds of undergoing primary amputation than urban whites (AOR, 1.21; 95% CI, 1.05-1.39). CONCLUSIONS: In these analyses, rurality was associated with greater odds for primary amputation in nonwhite patients but not in white patients. The effect of race on primary amputation was significant in both urban and rural settings; however, the effect was significantly stronger in rural settings. These findings suggest that race/ethnicity has a compounding effect on rural health disparities and that strategies to improve health of rural communities need to consider the particular needs of nonwhite residents to reduce disparities.

The incidence of esophageal cancer has increased faster than that of most cancers. Evidence from other malignant neoplasms suggests that diabetic patients have a worse response to multimodality therapy. We hypothesized that diabetic patients with esophageal cancer will have a decreased response to neoadjuvant chemotherapy and radiation therapy compared with nondiabetic patients.A retrospective study of The Society of Thoracic Surgeons General Thoracic Surgery Database identified all patients who had an esophagectomy after neoadjuvant therapy for esophageal cancer between 2012 and 2019. Patients were compared on the basis of the presence of diabetes. A pathologic complete response (pCR) was defined as ypT0 N0. The χOf the 9171 patients who met inclusion criteria, 2011 (22%) patients were diabetic and 7160 (78%) patients were nondiabetic. Patients with diabetes were older, more likely to be male, and more likely to have all comorbidities. Univariate analysis revealed that diabetic patients were less likely to have pCR (16% vs 18%; P = .026). Although multivariable analysis showed a trend toward diabetic patients' having lower odds of achieving pCR, diabetes was not independently associated with pCR (odds ratio, 0.89; 95% CI, 0.78-1.01; P = .075).Diabetic patients may be less likely than nondiabetic patients to achieve pCR after neoadjuvant treatment of esophageal cancer. This suggests the need for further exploration as diabetic patients with esophageal cancer can potentially benefit from different treatment paradigms compared with their nondiabetic counterparts.

ObjectivesAlthough amphetamine use is a growing health problem in the USA, there are limited data on amphetamine-related hospitalisations. The primary objective of our study was to examine trends in amphetamine-related hospitalisations in the USA between 2003 and 2014, including by age and sex. Our secondary objectives were to examine whether demographic, clinical and care setting characteristics were associated with select outcomes of amphetamine-related hospitalisations, including in-hospital mortality, prolonged length of stay and leaving against medical advice.Design, setting and participantsUsing the 2003–2014 National Inpatient Sample, we estimated the rate of amphetamine-related hospitalisations for each year in the USA among individuals 18+ years of age, stratified by age and sex. Subgroup analyses examined hospitalisations due to amphetamine causes. Unconditional logistic regression modelling was used to estimate the adjusted odds of admission outcomes for sociodemographic, clinical and hospital indicators.Primary and secondary outcomesOur primary outcome was amphetamine-related hospitalisations between 2003 and 2014; secondary outcomes included in-hospital mortality, prolonged length of stay and leaving against medical advice.ResultsAmphetamine-related hospitalisation rates increased from 27 to 69 per 100 000 population between 2003 and 2014. Annual rates were consistently greater among younger (18–44 years) individuals and men. Regional differences were observed, with admission to Western hospitals being associated with increased mortality (adjusted OR, AOR 5.07, 95% CI 1.22 to 21.04) and shorter (0–2 days) lengths of stay (AOR 0.70, 95% CI 0.58 to 0.83) compared with Northeast admissions. Males (AOR 1.26, 95% CI 1.15 to 1.38; compared with females) and self-pay (AOR 2.30, 95% CI 1.90 to 2.79; compared with private insurance) were associated with leaving against medical advice.ConclusionsIncreasing rates of amphetamine-related hospitalisation risk being overshadowed by other public health crises. Regional amphetamine interventions may offer the greatest population health benefits. Future studies should examine long-term outcomes among patients hospitalised for amphetamine-related causes.

Congenitally corrected transposition of the great arteries (ccTGA) has many management strategies, with the emergence of anatomic repair increasing the available surgical options. Contemporary surgical practices have not been described in multicenter analyses. This study describes the distribution of heart surgery in patients with ccTGA and defines contemporary outcomes in a large multicenter cohort.Index cardiovascular operations in patients with primary or fundamental diagnosis of ccTGA were identified in The Society of Thoracic Surgeons Congenital Heart Surgery Database from 2010 to 2019. Operations of interest were combined into mutually exclusive groups designating overall ccTGA management strategies. Outcomes were defined with standard Society of Thoracic Surgeons Congenital Heart Surgery Database definitions. Pearson χOne hundred one centers performed 985 index operations, with anatomic repair the most common approach. Twenty-six centers performed more than 10 operations. Atrial switch plus Rastelli operations had the highest rate of operative mortality (8.4%) and major complications (38.2%). Heart transplant operations had the longest postoperative length of stay among survivors (18 days [interquartile range, 13.5-26]).Patients with ccTGA remain a challenging cohort, with significant diversity in the operations used and a substantial burden of operative mortality and morbidity.

Background The Society of Thoracic Surgeons Congenital Heart Surgery Database Mortality Risk Model adjusts not only for procedure and age group pairings but also for additional patient factors, including the binary presence or absence of a chromosomal abnormality (CA), syndrome (S), and/or a noncardiac congenital anatomic abnormality (NCAA). This analysis refines case-mix adjustment by adding more granular adjustment for individual conditions (CA, S, and NCAA), consistent with a hypothesis that associated risk of mortality differs between individual conditions. Methods CA/S corresponding to the same condition were merged to a single condition code. Odds ratios were estimated for all CA/S. For CA/S associated with at least 10 deaths in neonates and infants and at least 10 deaths in children and adults, odds ratios were estimated for the effect of the CA/S separately in neonates/infants and in children/adults. In addition to these condition/age interactions, condition/age/procedure interactions were explored (eg, effect of Down syndrome was estimated based on age and procedure subgroups, including atrioventricular canal repair and single-ventricle palliation). Bayesian modeling was used to create 5 maximally homogeneous groups of CA/S from 81 candidate CA/S variables. A standard logistic regression model then incorporated indicator variables for the 5 categories of CAs/Ss, 7 unique NCAAs, and all other covariates in the previously published Society of Thoracic Surgeons Congenital Heart Surgery Database Mortality Model. Results Analysis included 107,062 operations in 100 centers (2010 to 2015). Operative Mortality was 3,629 (3.4%). In the development sample, the C statistics of the original nonaugmented model and the augmented model were 0.872 and 0.875, respectively. Conclusions The Society of Thoracic Surgeons Congenital Heart Surgery Database Mortality Risk Model has been augmented by addition of covariates representing individual CAs, Ss, and NCAAs.

Background Unlike coronary artery bypass and aortic and mitral valve procedures, there is no predictive risk model for aortic root replacement procedures. As a first step toward development of a risk model, this study analyzed The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database to determine factors predictive of mortality and morbidity in patients undergoing elective aortic root replacement (ARR). Methods The STS database was queried (from July 2011 to June 2016) for elective ARR with the following exclusion criteria: urgent or salvage cases, endocarditis, redo cardiac surgery, circulatory arrest, and aortic arch surgery. Adjusted multivariate logistic regression models for outcomes of mortality and composite STS morbidity were performed using covariates of the STS aortic valve risk set (expressed as odds ratios [ORs]). Results Of 24,244 patients undergoing ARR, 8,807 (77.6% male) met inclusion criteria in 808 centers; 33.7% (n = 2,965) had a bicuspid aortic valve, and 3.7% (n = 327) had Marfan syndrome. The median age was 58.0 years (interquartile range, 49 to 67 years). Median intensive care unit and hospital stays were 46 hours and 6 days, respectively. Significant predictors for mortality included: atrial fibrillation (OR, 2.06), body surface area (OR, 0.14), chronic obstructive pulmonary disease (OR, 1.2), New York Heart Association class IV (OR, 2.53), diabetes (OR, 2.48), coronary artery bypass grafting (OR, 2.77), mitral valve surgery (OR, ≥2.18), and Bentall operation (OR, 2.08). Regression analysis for risk factors for STS morbidity yielded 14 significant factors. A glomerular filtration rate increase of 20 units was predictive of improved mortality (OR, 0.85) and morbidity (OR, 0.91). Conclusions Elective ARR is performed with excellent postoperative outcomes. Analysis of the STS database reveals several significant risk factors that are independently associated with increased mortality and morbidity. The investigators anticipate that future studies inclusive of the nonelective ARR cases in the database will facilitate development of a risk model for root replacement procedures.

Background The primary surgical therapy for hypertrophic cardiomyopathy with obstruction is septal myectomy (SM). The current outcomes of SM with and without concomitant mitral operations in the United States was examined using The Society of Thoracic Surgeons database. Methods From July 2014 through June 2017, 4,274 SM operations were performed. Emergent status, endocarditis, aortic stenosis, and planned aortic valve operations were excluded. In the final cohort of 2,382 patients, 1,581 (66.4%) received SM alone (group 1), and 801 (33.6%) had SM with mitral valve repair or replacement (group 2). Group 2 was subdivided into mitral valve repair (MVr [n = 500]) and mitral valve replacement (MVR [n = 301]). Baseline characteristics were compared and risk-adjusted operative mortality and major morbidity were evaluated between treatment groups. Results Baseline comorbidity was lower in group 1 versus group 2 and for MVr versus MVR. Operative mortality and major morbidity was lower for group 1 versus 2 (1.6% versus 2.8%, p = 0.046, and 10.9% versus 20.0%, p Conclusions Septal myectomy for hypertrophic cardiomyopathy is safe. Septal myectomy alone may have risk-adjusted outcome advantages over SM with mitral valve repair or replacement. Septal myectomy and SM with MVr provide similar reduction in mitral regurgitation. Further longitudinal analyses are required to define technical efficacy and outcomes in selected pathoanatomic groups.

BACKGROUND: The impact of utilization of intraoperative transesophageal echocardiography (TEE) at the time of isolated coronary artery bypass grafting (CABG) on clinical decision making and associated outcomes is not well understood. OBJECTIVES: The purpose of this study was to determine the association of TEE with post-CABG mortality and changes to the operative plan. METHODS: A retrospective cohort study of planned isolated CABG patients from the Society of Thoracic Surgeons Adult Cardiac Surgery Database between January 1, 2011, and June 30, 2019, was performed. The exposure variable of interest was use of intraoperative TEE during CABG compared with no TEE. The primary outcome was operative mortality. The association of TEE with unplanned valve surgery was also assessed. RESULTS: Of 1,255,860 planned isolated CABG procedures across 1218 centers, 676,803 (53.9%) had intraoperative TEE. The proportion of patients receiving intraoperative TEE increased over time from 39.9% in 2011 to 62.1% in 2019 (p trend

Female patients with coronary artery disease have inferior outcomes compared with male patients, including higher mortality after coronary artery bypass graft surgery (CABG). We aimed to evaluate the association of female sex with the use of guideline-concordant CABG revascularization techniques.The Society of Thoracic Surgeons Adult Cardiac Surgery Database was queried for adult patients who underwent first-time isolated CABG in the United States from 2011 to 2019. The association between female sex and the odds of (1) receiving a left internal mammary artery graft for revascularization of the left anterior descending artery, (2) undergoing complete revascularization, and (3) undergoing multiarterial grafting was assessed, adjusting for procedural anatomy.Among 1,212,487 patients meeting inclusion criteria, 75% were male (n = 911,178) and 25% were female (n = 301,309). Female sex was associated with lower unadjusted rates of revascularization with an internal mammary artery graft (93.9% vs 95.9%, P.001), bilateral internal mammary artery graft (2.9% vs 5.6%, P.001), or radial artery graft (3.2% vs 5.6%, P.001). After adjustment, female patients had lower odds than males of receiving a left internal mammary artery graft to the left anterior descending artery (adjusted odds ratio 0.79; 95% confidence interval, 0.75 to 0.83; P.001), undergoing complete revascularization (adjusted odds ratio 0.86; 95% confidence interval, 0.83 to 0.90; P.001), and undergoing multiarterial grafting (adjusted odds ratio 0.78; 95% confidence interval, 0.75 to 0.81; P.001).Female sex was associated with 14% to 22% lower odds of undergoing guideline-concordant revascularization including left internal mammary artery to left anterior descending artery grafting, multiarterial grafting, and complete revascularization. Further investigation is necessary to determine why revascularization approaches differ by sex and to what degree sex disparities in coronary artery disease outcomes are due to surgical approach.

Introduction: Extracorporeal membrane oxygenation (ECMO) is a resource-intense modality whose usage is expanding rapidly. It is a costly endeavor and best conducted in a multidisciplinary setting. There is a growing impetus to mitigate the mortality and costs associated with ECMO. We sought to examine the impact of complications on mortality and hospital costs in patients on ECMO. Methods: Using the NIS database, we performed multivariable logistic regression to assess the influence of complications on the primary outcome, in-hospital mortality. Similarly, we performed multivariable survey linear regression analysis to evaluate the effect of the complications on hospital costs. Results: Of the 12,637 patients supported using ECMO between 2004 and 2013, 9836 (78%) developed at least one complication. The three most common complications were acute kidney injury (32.8%), bloodstream infection (31.8%), and bleeding (27.8%). An ECMO hospitalization with no complications was associated with median costs of $53,470, a single complication with costs of $97,560, two complications with costs of $139,035, and three complication with costs of $162,284. A single complication was associated with a 165% increase in odds of mortality. Two or three complications resulted in 375% or 627% higher odds of mortality, respectively. Having one, two, or three complications was associated with 24%, 38%, or 38% increase in median costs respectively (Figure 1). Complications associated with the highest median costs were central line-associated bloodstream infection $217,751; liver failure $176,201; bloodstream infection $169,529. Conclusion: In-hospital mortality and costs increase with each incremental complication in patients on ECMO. Accurate prediction and mitigation of complications is likely to improve outcomes and cost.

The relationship between institutional volume and operative mortality after surgical aortic valve replacement (SAVR) remains unclear.From January 2013 to June 2018, 234 556 patients underwent isolated SAVR (n = 144 177) or SAVR with coronary artery bypass grafting (CABG) (n = 90 379) within the Society of Thoracic Surgeons Adult Cardiac Surgery Database. The association between annualized SAVR volume (group 1 [1-25 SAVRs], group 2 [26-50 SAVRs], group 3 [51-100 SAVRs], and group 4 [100 SAVRs]) and operative mortality and composite major morbidity or mortality was assessed. Random effects models were used to evaluate whether historical (2013-2015) SAVR volume or risk-adjusted outcomes explained future (2016-2018) risk-adjusted outcomes.The annualized median number of SAVRs per site was 35 (interquartile range, 22-59; isolated aortic valve replacement [AVR], 20; AVR with CABG, 13). Among isolated SAVR cases, the mean operative mortality and composite morbidity or mortality were 1.5% and 9.7%, respectively, at the highest-volume sites (group 4), with significantly higher rates among progressively lower-volume groups (P trend.001). After adjustment, lower-volume centers had increased odds of operative mortality (group 1 vs group 4 [reference]: adjusted odds ratio [AOR] for SAVR, 2.24 [95% CI, 1.91-2.64]; AOR for SAVR with CABG, 1.96 [95% CI, 1.67-2.30]) and major morbidity or mortality (AOR for SAVR, 1.53 [95% CI, 1.39-1.69]; AOR for SAVR with CABG, 1.46 [95% CI, 1.32-1.61]) compared with the highest-volume institutions. Substantial variation in outcomes was observed across hospitals within each volume category, and prior outcomes explained a greater proportion of hospital operative outcomes than did prior volume.Operative outcomes after SAVR with or without CABG is inversely associated with institutional procedure volumes; however, prior outcomes are more predictive of future outcomes than is prior volume. Given the excellent outcomes observed at many lower-volume hospitals, procedural outcomes may be preferable to procedural volumes as a quality metric.

Highlights • Patients in the rural state of WV are at high-risk for atraumatic amputation. • There are opportunities for improved diabetes and vascular disease management in WV. • Patients at risk for vascular disease require preventive foot care and medication. • Amputation may represent a sentinel event that promotes patient behavior change., Lower extremity amputation due to peripheral artery disease (PAD) and diabetes (DM) is a life-altering event that identifies disparities in access to healthcare and management of disease. West Virginia (WV), a highly rural state, is an ideal location to study these disparities. The WVU longitudinal health system database was used to identify 1) risk factors for amputation, 2) how disease management affects the risk of amputation, and 3) whether the event of amputation is associated with a change in HbA1c and LDL levels. Adults (≥18 years) with diagnoses of DM and/or PAD between 2011 and 2016 were analyzed. Multivariable logistic regression analyses were performed on patients with lab information for both HbA1c and LDL while adjusting for patient factors to examine associations with amputations. In patients who underwent amputation, we compared laboratory values before and after using Wilcoxon signed rank tests. 50,276 patients were evaluated, 369 (7.3/1000) underwent amputation. On multivariable analyses, Male sex and Self-pay insurance had higher odds for amputation. Compared to patients with DM alone, PAD patients had 12.3 times higher odds of amputation, while patients with DM and PAD had 51.8 times higher odds of amputation compared to DM alone. We found significant associations between odds of amputation and HbA1c (OR 1.31,CI = 1.15–1.48), but not LDL. Following amputation, we identified significant decreases in lab values for HbA1c and LDL. These findings highlight the importance of medical optimization and patient education and suggest that an amputation event may provide an important opportunity for changes in disease management and patient behavior.

Aortic root translocation (Nikaidoh), Rastelli, and réparation à l'etage ventriculaire (REV) are repair options for transposition of the great arteries (TGA) with ventricular septal defects and left ventricular outflow tract obstruction (VSD-LVOTO) or double outlet right ventricle TGA type (DORV-TGA).This retrospective study using The Society of Thoracic Surgeons Congenital Heart Surgery Database evaluates surgical procedure utilization and outcomes of patients undergoing repair of TGA-VSD-LVOTO and DORV-TGA with a Nikaidoh, Rastelli, or REV procedure.A total of 293 patients underwent repair at 82 centers (January 2010 to June 2019). Most patients underwent a Rastelli (n = 165, 56.3%) or a Nikaidoh (n = 119, 40.6%) operation; only 3.1% (n = 9) underwent a REV. High-volume centers performed the majority of the repairs. Fewer Nikaidoh than Rastelli patients had prior cardiac operations (n = 57 [48.7%] vs n = 102 [63.0%]; P = .004). Nikaidohs had longer median cardiopulmonary bypass time (227 [interquartile range (IQR), 167-299] minutes vs 175 [IQR, 133-225] minutes; P.001) and median aortic cross-clamp times (131 [IQR, 91-175] minutes vs 105 [IQR, 82-141] minutes; P = .0015). Operative mortality was 3.1% (95% confidence interval [CI], 1.0%-7.0%; n = 5) for Rastelli, 4.4% (95% CI, 1.4%-9.9%; n = 5) for Nikaidoh, and 11.1% (95% CI, 0.3%-48.3%, n = 1) for REV. The rates of cardiac arrest, unplanned reoperation, mechanical circulatory support, prolonged ventilation, and permanent pacemaker placement were higher in the Nikaidoh population but with 95% CIs overlapping those of the other procedures.Rastelli and Nikaidoh procedures are the prevalent repair strategies for patients with DORV-TGA and TGA-VSD-LVOTO. Most are performed at high-volume institutions, and early outcomes are similar.

Head and neck malignancies are often treated with radiotherapy (RT). Nearly 80% of patients who have undergone RT will develop carotid radiation arteritis to some degree and 29% will develop stenosis50%. Surgery in a radiated neck has higher rates of complications, and carotid artery stenting (CAS) has become the primary therapy. The outcomes for CAS in patients with radiation arteritis have not been rigorously evaluated. The objective of the present study was to evaluate the differences in perioperative outcomes, restenosis rates, the need for reintervention, and freedom from mortality between RT patients and patients with atherosclerotic disease who had undergone CAS.The national Vascular Quality Initiative CAS dataset from 2016 to 2019 comprised the sample for analyses (n = 7343). The primary independent variable was previous head and/or neck RT. The primary endpoint was the interval to mortality. The secondary endpoints were the cumulative incidence of restenosis (50% and70% by duplex ultrasound) and reintervention. We also examined the following secondary perioperative endpoints: myocardial infarction, in-hospital mortality (death before discharge), neurologic events, ipsilateral stroke, and contralateral stroke. Kaplan-Meier and multivariable Cox proportional hazard models were used to assess for mortality, and cumulative incidence function estimates were used for the nonfatal endpoints.Of the 7218 patients, 1199 (17%) had undergone prior RT. We found a significant difference in the 3-year estimates of mortality for those with and without prior RT (9.4% and 7.5%, respectively; P = .03). Furthermore, on adjusted analysis, we observed a 58% increase in the risk of mortality for those with prior RT (adjusted hazard ratio, 1.58; 95% confidence interval, 1.13-2.21). We did not observe any differences in the risk of perioperative complications (myocardial infarction, in-hospital mortality, ipsilateral or contralateral stroke), restenosis (50% or70%), or reintervention for the prior RT group compared with those without RT.The CAS patients with RT had significantly greater mortality at all time points compared with those without RT, even after adjusting for other covariates. No significant difference was found in the incidence of perioperative complications, reintervention, or restenosis between the two groups. The present study is unique because of the large sample size and length of follow-up. The results suggest that for this high-risk group, CAS provides the same patency as it does for atherosclerotic carotid stenosis and avoids potentially morbid cranial nerve injury and wound healing complications.

The authors evaluated the type of anesthesia administered in atrial fibrillation ablation, hypothesizing that monitored anesthesia care is used less frequently than general anesthesia.A retrospective study.National Anesthesia Clinical Outcomes Registry data, which are multi-institutional from across the United States.Adult patients who underwent elective atrial fibrillation ablation between 2013 and 2018.None.National Anesthesia Clinical Outcomes Registry data were evaluated, and covariates were selected a priori within multivariate models to assess for predictors of anesthetic type. A total of 54,321 patients underwent atrial fibrillation ablation; 3,251 (6.0%) received monitored anesthesia care. Patients who received monitored anesthesia care were more likely to be80 years old (12.4% v 4.9%; p0.0001), female (36.1% v 34.3%; p0.0001), have American Society of Anesthesiologists physical statusIII (17.28% v 10.48%; p0.0001), and reside in urban areas (62.23% v 53.37%; p0.0001). They received care in the Northeast (17.6% v 10.1%; p0.0001) at low-volume centers (median 224 v 284 procedures; p0.0001). Multivariate analysis revealed that each five-year increase in age, being female, and having an American Society of Anesthesiologists physical statusIII resulted in a 7% (p0.0001), 9% (p = 0.032), and 200% (p0.0001) increased odds of receiving monitored anesthesia care, respectively. Requiring additional ablation of atria or of a second arrhythmia and residing outside the Northeast resulted in a decreased odds of monitored anesthesia care (adjusted odds ratio 0.24 [p=0.002] and0.5 [p0.03], respectively). For each 50 cases performed annually at a center, the odds decreased by 5% (p = 0.005).General anesthesia is the most common type of anesthesia administered for atrial fibrillation ablation. The type of anesthesia administered, however, varies with patient, procedural, and hospital characteristics.

Airway anomalies are common in children with cardiac disease but with an unquantified impact on outcomes. We sought to define the association between airway anomalies and tracheal surgery with cardiac surgery outcomes using the Society of Thoracic Surgery Congenital Heart Surgery Database.Index cardiac operations in children aged less than 18 years (January 2010 to September 2018) were identified from the Society of Thoracic Surgery Congenital Heart Surgery Database. Patients were divided on the basis of reported diagnosis of an airway anomaly and subdivided on the basis of tracheal lesion and tracheal surgery. Multivariable analysis evaluated associations between airway disease and outcomes controlling for covariates from the Society of Thoracic Surgery Congenital Heart Surgery Database Mortality Risk Model.Of 198,674 index cardiovascular operations, 6861 (3.4%) were performed in patients with airway anomalies, including 428 patients (0.2%) who also underwent tracheal operations during the same hospitalization. Patients with airway anomalies underwent more complex cardiac operations (45% vs 36% Society of Thoracic Surgeons/European Association for Cardiothoracic Surgery Congenital Heart Surgery Mortality category ≥3 procedures) and had a higher prevalence of preoperative risk factors (73% vs 39%; both P .001). In multivariable analysis, patients with airway anomalies had increased odds of major morbidity and tracheostomy (P .001). Operative mortality was also increased in patients with airway anomalies, except those with malacia. Tracheal surgery within the same hospitalization increased the odds of operative mortality (adjusted odds ratio, 3.9; P .0001), major morbidity (adjusted odds ratio, 3.7; P .0001), and tracheostomy (adjusted odds ratio, 16.7; P .0001).Patients undergoing cardiac surgery and tracheal surgery are at significantly higher risk of morbidity and mortality than patients receiving cardiac surgery alone. Most of those with unoperated airway anomalies have higher morbidity and mortality, which makes it an important preoperative consideration.

Fontan failure often requires surgical therapy in the form of Fontan revision or heart transplantation. We sought to characterize national trends in the surgical burden of Fontan failure and identify risk factors for adverse outcomes.Fontan patients undergoing Fontan revision or transplantation from January 2010 to June 2018 were included. We evaluated baseline characteristics and outcomes and used multivariable logistic regression to identify risk factors for operative mortality and composite mortality and major morbidity.A total of 1135 patients underwent Fontan revision (n = 598) or transplantation (n = 537) at 100 centers. Transplantations increased from 34 in 2010 to 76 in 2017, largely owing to an increase in patients with hypoplastic left heart syndrome (HLHS) (18 in 2010 to 49 in 2017), while Fontan revision decreased (75 in 2010 to 49 in 2017). Transplantation patients were younger (median 14 years of age vs 18 years of age; P.001), more often had preoperative risk factors (66% vs 40%; P.001), and more often had HLHS (51% vs 15%; P.001). Operative mortality and composite major morbidity and mortality were 7.6% and 35% for transplantation and 7.1% and 22% for Fontan revision, respectively. Multivariable risk factors for mortality included older age (odds ratio [OR], 1.08/y; P = .007), presence of preoperative risk factors (OR, 3.33; P = .002), and concomitant pulmonary artery reconstruction (OR, 2.7; P = .029) for Fontan revision but only older age (OR, 1.06/y; P = .020) for transplantation.Both transplantation and Fontan revision are associated with high morbidity and mortality. There has been evolution of practices in surgical therapy for Fontan failure, perhaps related to rising prevalence of HLHS staged palliation.

Background The long-term effects of postoperative complications following coronary artery bypass grafting (CABG) are unknown. Methods Medicare-linked records from the Society of Thoracic Surgeons Adult Cardiac Surgery Database were queried for isolated CABG records from 2007 through 2012. Unadjusted and adjusted associations between individual postoperative complications and both mortality and all-cause rehospitalization were evaluated to 7 years using Cox proportional-hazards models and cumulative incidence functions. Because of nonproportional hazards, associations are presented as early (0 to 90 days) and late (90 days to 7 years). Results Of the 294,533 isolated CABG patients who had records linked to Medicare for long-term follow-up (median age, 73 years; 30% female), 120,721 (41%) experienced at least 1 of the complications of interest, including new-onset atrial fibrillation (30.0%), prolonged ventilation (12.3%), renal failure (4.5%), reoperation (3.5%), stroke (1.9%), and sternal wound infection (0.4%). Each of the 6 postoperative complications was associated with a significantly increased risk of mortality and rehospitalization to 7 years despite adjustment for baseline characteristics and the presence of multiple complications. Although the predominant effect of postoperative complications was observed in the first 90 days, the increased risk-adjusted hazard for death and rehospitalization continued through 7 years. Conclusions Postoperative complications are associated with an increased risk of both early and late mortality and all-cause rehospitalization, particularly during the “value” window within 90 days of CABG. These findings underscore the need to develop avoidance strategies as well as cost-adjustment methods for each of these complications.

Data from The Society of Thoracic Surgeons Adult Cardiac Surgery Database were analyzed to identify trends in patient characteristics and outcomes of mitral valve operations in North America.All patients with isolated primary mitral valve operations with or without tricuspid valve repair, surgical atrial fibrillation ablation, or atrial septal defect closure performed July 2011 to September 2016 were identified. A subgroup analysis assessed patients with degenerative leaflet prolapse (DLP).Isolated primary mitral valve operations were performed on 87,214 patients at 1,125 centers, increasing by 24% between 2011 (n = 14,442) and 2016 (n = 17,907). The most common etiology was DLP (60.7%); 4.3% had functional mitral regurgitation. Preoperatively, 47.3% of patients had an ejection fraction less than 60% and 34.2% had atrial fibrillation. Overall mitral valve repair rate was 65.6%, declining from 67.1% (2011) to 63.2% (2016; p 0.0001). Repair rates were related to etiology (DLP, 82.5%; rheumatic, 17.5%). Of the 29,970 mitral valve replacements, 16.2% were preceded by an attempted repair. Repair techniques included prosthetic annuloplasty (94.3%), leaflet resection (46.5%), and artificial cord implantation (22.7%). Bioprosthetic valves were implanted with increasing frequency (2011, 65.4%; 2016, 75.8%; p 0.0001). Less-invasive operations were performed in 23.0% and concomitant tricuspid valve repair in 15.7%. Unadjusted operative mortality was 3.7% (replacements) and 1.1% (repairs).Patients undergoing primary isolated mitral valve operations commonly have ventricular dysfunction, atrial fibrillation, and heart failure. Although contemporary outcomes are excellent, earlier guideline-directed referral and increased frequency and quality of repair may further improve results of mitral valve operations.

The goal of this study was to determine the relationship of prosthesis-patient mismatch (PPM) with long-term survival and to assess whether growing concern about PPM has resulted in a decreased incidence over time.Using The Society of Thoracic Surgeons Adult Cardiac Surgery Database, we identified 59,779 patients ≥65 years old who underwent isolated surgical aortic valve replacement (AVR) between 2004 and 2014. The degree of PPM was calculated using literature-derived effective orifice areas for commonly used valves. Outcomes to 10 years were stratified by degree of PPM.The distribution of PPM was as follows: 35%, none (n = 21,053); 54%, moderate (n = 32,243); and 11%, severe (n = 6,483). Compared with patients with no PPM, patients with moderate or severe PPM had a significantly increased risk of readmission for heart failure (hazard ratio [HR], 1.15; 95% confidence interval [CI], 1.09 to 1.21; HR, 1.37; 95% CI, 1.26 to 1.48) and redo AVR (HR, 1.41; 95% CI, 1.13 to 1.77; HR, 2.68; 95% CI, 2.01 to 3.56) for moderate or severe PPM, respectively. Survival was significantly worse for any degree of PPM (moderate to none: HR, 1.08; 95% CI, 1.05 to 1.12; severe to none: HR, 1.32; 95% CI, 1.25 to 1.39), with 10-year adjusted survival rates of 46%, 43%, and 35% for none, moderate, and severe, respectively (p0.001). The incidence of severe PPM decreased by 55% over the study period, from 13.8% in 2004 to 6.2% in 2014.Any degree of PPM significantly decreased long-term survival and increased readmission rates for both heart failure and reoperation for AVR. Temporal trends show a significant decrease in the incidence of PPM over the past decade.

Background: We sought to evaluate differences in primary anesthetic type used in arteriovenous access creation with the hypothesis that administration of regional anesthesia and monitored anesthesia care (MAC) with local anesthesia as the primary anesthetic has increased over time. Methods: National Anesthesia Clinical Outcomes Registry data were retrospectively evaluated. Covariates were selected a priori within multivariate models to determine predictors of anesthetic type in adults who underwent elective arteriovenous access creation between 2010 and 2018. Results: A total of 144,392 patients met criteria; 90,741 (62.8%) received general anesthesia. The use of regional anesthesia and MAC decreased over time (8.0%–6.8%, 36.8%–27.8%, respectively; both p III and to reside in rural areas (52.3% and 12.9%, respectively; both p III, and each 5-year increase in age resulted in increased odds of receiving alternatives to general anesthesia (regional anesthesia adjusted odds ratios (AORs) 1.06, 1.12, and 1.26, MAC AORs 1.09, 1.2, and 1.1, respectively; all p Conclusions: Use of regional anesthesia and MAC with local anesthesia for arteriovenous access creation has decreased over time with general anesthesia remaining the primary anesthetic type. Anesthetic choice, however, varies with patient characteristics and geography.
