- Abstract
BACKGROUND: Gaps between evidence and practice in the care of patients with chronic heart failure (CHF) in the United States suggest major opportunities for improvement. However, the organizational factors and implementation approaches that influence adherence to national guidelines are poorly understood. OBJECTIVES: The objectives of this study were to explore the degree to which providers in the Veterans Health Administration system adhere to CHF clinical practice guidelines, and to identify facility-level factors influencing adherence. DESIGN: In a national cross-sectional study, facility quality managers were surveyed regarding quality improvement efforts, guideline implementation, and context. These data were linked to organizational structure data and provider adherence data from chart reviews. The unit of analysis was the facility. The data were adjusted for the average number of comorbidities per CHF patient. Multivariate logistic regression models were constructed to model factors affecting adherence to CHF guidelines. SAMPLE: The sample consisted of 143 Veterans Administration Medical Centers with ambulatory care clinics. RESULTS: The quality manager survey included data from 91% of facilities. Facility-level estimates of provider adherence measures were, on average, 85% or more for most measures. In multivariate analyses, facilities with higher levels of adherence were more likely to have: (1) providers who had been given a brief guideline summary, (2) providers receptive to the guidelines, (3) guideline-specific task forces to support implementation, and 4) a well-planned implementation process. CONCLUSIONS: Healthcare organizations should adapt implementation to meet local conditions, including creating guideline-specific task forces, developing a well-planned implementation process, fostering provider buy-in, and providing guideline summaries to providers.

- Abstract
Hospitals use numerous guideline implementation approaches with varying success. Approaches have been classified as consistently, variably, or minimally effective, with multiple approaches being most effective. This project assesses the Department of Veterans Affairs (VA) use of effective guideline implementation approaches. A survey of 123 VA quality managers assessed the approaches used to implement the chronic obstructive pulmonary disease, diabetes mellitus, congestive heart failure, and major depressive disorder guidelines. Approaches were categorized based on their effectiveness, and the total number of approaches used was calculated. Commonly used approaches were clinical meetings, summaries, and revised forms. Consistently and minimally effective approaches were used most frequently. Most hospitals used 4-7 approaches. Odds ratios demonstrated that consistently effective approaches were paired with minimally and variably effective approaches. The frequent use of consistently effective approaches and multiple approaches benefits VA adherence. However, VA hospitals should consider selective combinations of approaches to ensure the use of the most effective implementation methods. [ABSTRACT FROM AUTHOR]

- Abstract
Provider knowledge is a potential barrier to adherence to clinical guidelines. The purpose of this study is to assess the impact of organizational, provider, and guideline factors on provider knowledge of a congestive heart failure (CHF) clinical practice guideline (CPG) in the Veterans Health Administration (VHA) health care system. We developed a survey to investigate institution-level factors influencing the effectiveness of guideline implementation, including characteristics of the guideline, providers, hospital culture and structure, and regional network. Survey participants were quality managers, primary care administrators, and other individuals involved in primary care CPG implementation at 143 VHA hospitals with ambulatory care clinics. Potential explanatory variables were grouped into 11 factors. Multivariate regression models assessed the association between these factors and reported levels of provider knowledge regarding the CHF guideline at the hospital level. Two hundred forty surveys from 126 of 143 (88%) VHA hospitals were returned. Provider knowledge of the CHF guideline was estimated as "great" or "very great" by 58% of respondents. Three predictor factors (dissemination approaches, use of technology in guideline implementation, and hospital culture) were independently associated (P < or = .05) with provider knowledge. Specific variables within these categories that were related to greater knowledge included physician belief that guidelines were applicable to their practice, distribution of guideline summaries, use of guideline storyboards in clinic areas, the use of technology (eg, electronic patient records) in CPG implementation, and establishment of implementation checkpoints and deadlines. Provider knowledge of guidelines is affected by factors at various organizational levels: dissemination approaches, use of technology, and hospital culture. Guideline implementation efforts that target multiple organizational levels may increase provider knowledge. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Tricuspid atresia (TA) is the second most common form of functionally univentricular heart. For patients with TA and normally related great arteries (Type I), left ventricular outflow tract obstruction (LVOTO) is rare., Methods: From the Congenital Heart Surgeons' Society multi-institutional cohort of 445 patients with Type I TA enrolled from 1999 to 2024 from 42 sites, 14 infants (3%) had interventions for associated LVOTO, either at presentation or after their first TA-related intervention., Results: Of seven infants initially undergoing Norwood/Damus-Kaye-Stansel (DKS), six survived to Stage II, of whom five survived with one developing pulmonary hypertension and four achieving Fontan. An additional seven infants who were first managed with pulmonary artery band placement subsequently had bidirectional superior cavopulmonary anastomosis (BCPA) and a DKS procedure; there were six survivors, all achieving Fontan. All ten survivors who underwent the Fontan procedure had normal left ventricular and mitral valve function at the latest follow-up. The overall Kaplan-Meier survival estimate at 20 years for these 14 patients was 79% (70% CI, 66%-88%), and the median follow-up was 8.3 years (0.24-21.5)., Conclusions: While infants with TA and transposition of the great arteries are more likely to have LVOTO, this can also occur in the setting of normally related great arteries. Infants with Type I TA and LVOTO can be managed in the neonatal period with the Norwood procedure ensuring complete arch relief with acceptable outcomes. If LVOTO becomes evident after initial pulmonary artery band placement, a subsequent DKS procedure facilitates satisfactory success to Fontan., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Background: Society of Thoracic Surgeons Congenital Heart Surgery Database is the largest congenital heart surgery database worldwide but does not provide information beyond primary episode of care. Linkage to hospital electronic health records would capture complications and comorbidities along with long-term outcomes for patients with CHD surgeries. The current study explores linkage success between Society of Thoracic Surgeons Congenital Heart Surgery Database and electronic health record data in North Carolina and Georgia., Methods: The Society of Thoracic Surgeons Congenital Heart Surgery Database was linked to hospital electronic health records from four North Carolina congenital heart surgery using indirect identifiers like date of birth, sex, admission, and discharge dates, from 2008 to 2013. Indirect linkage was performed at the admissions level and compared to two other linkages using a "direct identifier," medical record number: (1) linkage between Society of Thoracic Surgeons Congenital Heart Surgery Database and electronic health records from a subset of patients from one North Carolina institution and (2) linkage between Society of Thoracic Surgeons data from two Georgia facilities and Georgia's CHD repository, which also uses direct identifiers for linkage., Results: Indirect identifiers successfully linked 79% (3692/4685) of Society of Thoracic Surgeons Congenital Heart Surgery Database admissions across four North Carolina hospitals. Direct linkage techniques successfully matched Society of Thoracic Surgeons Congenital Heart Surgery Database to 90.2% of electronic health records from the North Carolina subsample. Linkage between Society of Thoracic Surgeons and Georgia's CHD repository was 99.5% (7,544/7,585)., Conclusions: Linkage methodology was successfully demonstrated between surgical data and hospital-based electronic health records in North Carolina and Georgia, uniting granular procedural details with clinical, developmental, and economic data. Indirect identifiers linked most patients, consistent with similar linkages in adult populations. Future directions include applying these linkage techniques with other data sources and exploring long-term outcomes in linked populations.

- Abstract
Adults with congenital heart disease (CHD) benefit from cardiology follow-up at recommended intervals of ≤ 2 years. However, benefit for children is less clear given limited studies and unclear current guidelines. We hypothesize there are identifiable risks for gaps in cardiology follow-up in children with CHD and that gaps in follow-up are associated with differences in healthcare utilization. Our cohort included children < 10 years old with CHD and a healthcare encounter from 2008 to 2013 at one of four North Carolina (NC) hospitals. We assessed associations between cardiology follow-up and demographics, lesion severity, healthcare access, and educational isolation (EI). We compared healthcare utilization based on follow-up. Overall, 60.4% of 6,969 children received cardiology follow-up within 2 years of initial encounter, including 53.1%, 58.1%, and 79.0% of those with valve, shunt, and severe lesions, respectively. Factors associated with gaps in care included increased drive time to a cardiology clinic (Hazard Ratio (HR) 0.92/15-min increase), EI (HR 0.94/0.2-unit increase), lesion severity (HR 0.48 for shunt/valve vs severe), and older age (HR 0.95/month if < 1 year old and 0.94/year if > 1 year old; p < 0.05). Children with a care gap subsequently had more emergency department (ED) visits (Rate Ratio (RR) 1.59) and fewer inpatient encounters and procedures (RR 0.51, 0.35; p < 0.05). We found novel factors associated with gaps in care for cardiology follow-up in children with CHD and altered health care utilization with a gap. Our findings demonstrate a need to mitigate healthcare barriers and generate clear cardiology follow-up guidelines for children with CHD., (© 2024. The Author(s).)

- Abstract
Care and outcomes for the more than 40,000 patients undergoing pediatric and congenital heart surgery in the United States annually are known to vary widely. While consensus recommendations have been published across numerous fields as one mechanism to promote a high level of care delivery across centers, it has been more than two decades since the last pediatric heart surgery recommendations were published in the United States. More recent guidance is lacking, and collaborative efforts involving the many disciplines engaged in caring for these children have not been undertaken to date. The present initiative brings together professional societies spanning numerous care domains and congenital cardiac surgeons, pediatric cardiologists, nursing, and other healthcare professionals from diverse programs around the country to develop consensus recommendations for United States centers. The focus of this initial work is on pediatric heart surgery, and it is recommended that future efforts focus in detail on the adult congenital population. We describe the background, rationale, and methodology related to this collaborative effort, and recommendations put forth for Essential Care Centers (essential services necessary for any program), and Comprehensive Care Centers (services to optimize comprehensive and high-complexity care), encompassing structure, process, and outcome metrics across 14 domains., (Copyright © 2023 [Author/Employing Institution].

- Abstract
Background: Studies examining the volume-outcome relationship in congenital heart surgery (CHS) are more than a decade old. Since then, mortality has declined, and case-mix adjustment has evolved. We determined the current relationship between hospital CHS volume and outcomes., Methods: Patients aged ≤18 years undergoing index operations in The Society of Thoracic Surgeons-Congenital Heart Surgery Database (2017-2020) were included. Associations between annual hospital volume and case-mix-adjusted operative mortality, major complications, failure to rescue (FTR), and postoperative length of stay (PLOS) were assessed using Bayesian hierarchical models, overall, by The Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery (STAT) category, and for the Norwood procedure., Results: Across 101 centers (76,714 index operations), median annual volume was 144 operations/y. Operative mortality was 2.7%. Lower-volume hospitals had higher mortality, with an apparent transition zone at ∼190 operations/y (95% credible interval [CrI], 115-450 operations/y), below which a sustained uptick in the estimated odds of death occurred. Odds of death compared with a 450 operations/y reference were 50 operations/y (odds ratio [OR], 1.84; 95% CrI, 1.41-2.37), 100 operations/y (OR, 1.37; 95% CrI, 1.08-1.71), 200 operations/y (OR, 0.92; 95% CrI, 0.1-1.18), 300 operations/y (OR, 0.89; 95% CrI, 0.76-1.04). The volume-outcome effect was more apparent for STAT 4 to 5 than STAT 1 to 3 operations. In the overall cohort, PLOS and complications were similar across hospital volumes, whereas FTR rates were higher at lower-volume hospitals. Lower-volume hospitals had worse outcomes after the Norwood procedure, most notably mortality and FTR., Conclusions: Hospital volume is associated with mortality and FTR after CHS. The relationship is strongest for high-risk operations. These data can inform ongoing initiatives to improve CHS care., (Copyright © 2023 The Society of Thoracic Surgeons. Published by Elsevier Inc.

- Abstract
Objectives: Identifying the optimal solution for young adults requiring aortic valve replacement (AVR) is challenging, given the variety of options and their lifetime complication risks, impacts on quality of life, and costs. Decision analytic techniques make comparisons incorporating these measures. We evaluated lifetime valve-related outcomes of mechanical aortic valve replacement (mAVR) versus the Ross procedure (Ross) using decision tree microsimulations modeling., Methods: Transition probabilities, utilities, and costs derived from published reports were entered into a Markov model decision tree to explore progression between health states for hypothetical 18-year-old patients. In total, 20,000 Monte Carlo microsimulations were performed to model mortality, quality-adjusted-life-years (QALYs), and health care costs. The incremental cost-effectiveness ratio (ICER) was calculated. Sensitivity analyses was performed to identify transition probabilities at which the preferred strategy switched from baseline., Results: From modeling, average 20-year mortality was 16.3% and 23.2% for Ross and mAVR, respectively. Average 20-year freedom from stroke and major bleeding was 98.6% and 94.6% for Ross, and 90.0% and 82.2% for mAVR, respectively. Average individual lifetime (60 postoperative years) utility (28.3 vs 23.5 QALYs) and cost ($54,233 vs $507,240) favored Ross over mAVR. The average ICER demonstrated that each QALY would cost $95,345 more for mAVR. Sensitivity analysis revealed late annual probabilities of autograft/left ventricular outflow tract disease and homograft/right ventricular outflow tract disease after Ross, and late death after mAVR, to be important ICER determinants., Conclusions: Our modeling suggests that Ross is preferred to mAVR, with superior freedom from valve-related morbidity and mortality, and improved cost-utility for young adults requiring aortic valve surgery., Competing Interests: T.K. serves as a consultant for Edwards Lifesciences.

- Abstract
Children with congenital heart defects (CHDs) are at risk for poor academic performance. The degree to which receipt of health care services is associated with adverse academic outcomes is not known. We examined the association between episodes of cardiac care and third-grade performance in children with CHD. We identified subjects between 1/1/2008 and 4/30/2012 among 5 centers in North Carolina. We classified children by CHD type and linked subjects to the state educational records. Any inpatient or outpatient cardiac encounter on a date of service was considered an encounter. We calculated the number of encounters by adding the number of inpatient or outpatient cardiac visits prior to the date of the end-of-grade (EOG) tests. We estimated the odds of failing third-grade reading or math EOG tests by episodes of care stratified at the 50th percentile, controlling for CHD type, maternal education, sex, race/ethnicity, birth weight, and gestational age. A total of 184 children had third-grade EOG scores linked to health care records. The median number of episodes of care was 4 (range: 1-60). Those with visits ˃ 50th percentile (> 4 encounters/year over the 4.3 year observation period) had 2.09 (95% CI 1.04, 4.21) greater odds of failing the math EOG compared to those ≤ 50th percentile (1-4 encounters). The third-grade math score declined by 1.5 points (P < 0.008) for every 10 episodes of care. There was no association of episodes of care on third-grade reading performance. Children with CHD with > 4 episodes of cardiac care/year may be at risk for delays in third-grade academic performance. Strategies to minimize school absenteeism may improve academic success in this population., (© 2022.

- Abstract
Background: The AHA/ACC Adult Congenital Heart Disease guidelines recommend that most adults with congenital heart disease (CHD) follow-up with CHD cardiologists every 1 to 2 years because longer gaps in care are associated with adverse outcomes. This study aimed to determine the proportion of patients in North Carolina who did not have recommended follow-up and to explore predictors of loss to follow-up., Methods: Patients ages ≥18 years with a healthcare encounter from 2008 to 2013 in a statewide North Carolina database with an ICD-9 code for CHD were assessed. The proportion with cardiology follow-up within 24 months following index encounter was assessed with Kaplan-Meier estimates. Cox regression was utilized to identify demographic factors associated with differences in follow-up., Results: 2822 patients were identified. Median age was 35 years; 55% were female. 70% were white, 22% black, and 3% Hispanic; 36% had severe CHD. The proportion with 2-year cardiology follow-up was 61%. Those with severe CHD were more likely to have timely follow-up than those with less severe CHD (72% vs 55%, P < .01). Black patients had a lower likelihood of follow-up than white patients (56% vs 64%, P = .01). Multivariable Cox regression identified younger age, non-severe CHD, and non-white race as risk factors for a lower likelihood of follow-up by 2 years., Conclusion: 39% of adults with CHD in North Carolina are not meeting AHA/ACC recommendations for follow-up. Younger and minority patients and those with non-severe CHD were particularly vulnerable to inadequate follow-up; targeted efforts to retain these patients in care may be helpful.

- Abstract
Objective: Tricuspid atresia with normally related great vessels (TA) is considered the optimal substrate for the Fontan pathway. The factors associated with death or transplantation after cavopulmonary shunt (CPS) are underappreciated. We aimed to determine factors associated with CPS-Fontan interstage death/transplantation versus transition to Fontan in TA., Methods: A total of 417 infants younger than 3 months of age with TA were enrolled (January 1999 to February 2020) from 40 institutions into the Congenital Heart Surgeons' Society TA cohort. Parametric competing risk methodology was used to determine factors associated with the competing end points of death/transplantation without Fontan completion, and transition to Fontan., Results: CPS was performed in 382 patients with TA; of those, 5% died or underwent transplantation without transition to Fontan and 91% transitioned to Fontan by 5 years after CPS. Prenatal diagnosis (hazard ratio [HR], 0.74; P < .001) and pulmonary artery band (PAB) at CPS (HR, 0.50; P < .001) were negatively associated with Fontan completion. Preoperative moderate or greater mitral valve regurgitation (HR, 3.0; P < .001), concomitant mitral valve repair (HR, 11.0; P < .001), PAB at CPS (HR, 3.0; P < .001), postoperative superior vena cava interventions (HR, 9.0; P < .001), and CPS takedown (HR, 40.0; P < .001) were associated with death/transplantation., Conclusions: The mortality rate after CPS in patients with TA is notable. Those with preoperative mitral valve regurgitation remain a high-risk group. PAB at the time of CPS being associated with both increased risk of death and decreased Fontan completion may represent a deleterious effect of antegrade pulmonary blood flow in the CPS circulation., (Copyright © 2021 The American Association for Thoracic Surgery.

- Abstract
Purpose of Review: Decentralized, inconsistent healthcare delivery results in variable outcomes and wastes nearly one trillion dollars annually in the United States (US). Congenital heart surgery (CHS) is not immune due to high, variable costs and inconsistent outcomes across hospitals. Many European countries and Canada have addressed these issues by regionalizing CHS. Centralizing resources lowers costs, reduces in-hospital mortality and improves long-term survival. Although the impact on travel distance for patients is limited, the effect on healthcare disparities requires study. This review summarizes current data and integrates these into paths to regionalization through health policy, research, and academic collaboration., Recent Findings: There are too many CHS programs in the US with unnecessarily high densities of centers in certain regions. This distribution lowers center and surgeon case volumes, creates redundancy, and increases variation in costs and outcomes. Simultaneously, adhering to suboptimal allocation impedes the understanding of optimal regionalization models to optimize congenital cardiac care delivery., Summary: CHS regionalization models developed for the US increase surgeon and center volume, decrease healthcare spending, and improve patient outcomes without substantially increasing travel distance. Regionalization in countries with few or no existing CHS programs is yet to be explored, but may be associated with more efficient spending and procedural complexity expansion., (Copyright © 2021 Wolters Kluwer Health, Inc.

- Abstract
Background: Over 150 hospitals perform congenital heart surgery (CHS) in the United States. Many hospitals are close together, with a median patient travel distance of 38.5 miles. We began with a theoretical blank slate and used objective methodology guided by population density and volume thresholds to estimate the optimal number and locations of hospitals to provide CHS in the United States., Methods: Guided by published data, we estimated the number of CHS operations in the United States in to be 32,500 per year. We distributed patients geographically based on population density. Metropolitan Statistical Areas (population centers and surrounding areas with close economic/social ties) were used as potential hospital locations. Patients were assigned to the closest hospital location such that all hospitals had a CHS volume of ≥300 operations., Results: We estimated 57 hospitals could serve the contiguous United States. Median theoretical hospital volume after regionalization was 451 operations (interquartile range, 366-648). Median patient travel distance was 35.1 miles. Some patients (6396/31,895, 20%) traveled more than 100 miles., Conclusions: Our model suggests the United States could be served by approximately 100 fewer CHS hospitals than currently exist. With hospitals optimally placed, patient travel burden would decrease. This model serves as a platform to improve care delivery by regionalization of CHS., (Copyright © 2021 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.)

- Abstract
Objective: Pediatric extracorporeal membrane oxygenation typically necessitates protracted ventilator support, yet not much is known about the use of tracheostomy in the pediatric subpopulation. The study was designed with an objective to quantify the prevalence of tracheostomy in children with respiratory/cardiac failure requiring extracorporeal membrane oxygenation and to compare outcomes for patients undergoing early, late, and no tracheostomy., Methods: Data of patients <18 years of age who underwent extracorporeal membrane oxygenation for respiratory/cardiac failure between 2009 and 2015 were obtained from the Virtual Pediatric Systems (VPS, LLC) Database. Patients who underwent post-operative cardiac ECMO were excluded. Early versus late tracheostomy was defined as ⩽21 or >21 days after intensive care unit admission., Results: Data were analyzed for 2127 patients meeting inclusion and exclusion criteria. Five percent (107/2127) underwent a tracheostomy. Of these, 28% (30/107) underwent early and 72% (77/107) late tracheostomy. A higher mortality was found in the no tracheostomy group (41.3%) compared to early (13.3%) and late tracheostomy (14.3%) groups. Late tracheostomy was associated with 2.4 times the expected intensive care unit length of stay and 1.87 times the expected ventilator days as compared to patients with no tracheostomy. Early tracheostomy was associated with a shorter intensive care unit length of stay (p value < 0.001) and ventilator days (p value = 0.04) compared to late tracheostomy and no difference with the no tracheostomy group., Conclusions: Late tracheostomy (>21 days) is associated with worse outcomes in the cohort of children who underwent Pediatric extracorporeal membrane oxygenation compared to patients who did not undergo tracheostomy. Early tracheostomy is associated with shorter intensive care unit stay and ventilator duration when compared to late tracheostomy.

- Abstract
The objective of this study is to simulate regionalization of congenital heart surgery (CHS) in the United States and assess the impact of such a system on travel distance and mortality. Patients ≤18 years of age who underwent CHS were identified in 2012 State Inpatient Databases. Operations were stratified by the Risk Adjustment for Congenital Heart Surgery, version 1 (RACHS-1) method, with high risk defined as RACHS-1 levels 4-6. Regionalization was simulated by progressive closure of hospitals, beginning with the lowest volume hospital. Patients were moved to the next closest hospital. Analyses were conducted (1) maintaining original hospital mortality rates and (2) estimating mortality rates based on predicted surgical volumes after absorbing moved patients. One hundred fifty-three hospitals from 36 states performed 1 or more operation (19,064 operations). With regionalization wherein, all hospitals performed >310 operations, 37 hospitals remained, from 12.5% to 17.4% fewer deaths occurred (83-116/666), and median patient travel distance increased from 38.5 to 69.6 miles (P < 0.01). When only high-risk operations were regionalized, 3.9-5.9% fewer deaths occurred (26-39/666), and the overall mortality rate did not change significantly. Regionalization of CHS in the United States to higher volume centers may reduce mortality with minimal increase in patient travel distance. Much of the mortality reduction may be missed if solely high-risk patients are regionalized., (Copyright © 2019 Elsevier Inc. All rights reserved.)

- Abstract
Objectives: Improved survival has led to interest in functional health status (FHS) as patients with dextro-transposition of the great arteries (d-TGA) transition to adulthood. Our primary objectives were (1) evaluation of The Medical Outcomes Study Short Form-36 Health Survey (SF-36) results; (2) comparison with results of patients who completed the Child Health Questionnaire-Child Form 87 (CHQ-CF87) previously, or the PedsQL Generic Core Scales (PedsQL) survey subsequently; and (3) determination of factors associated with SF-36 domains., Methods: Survivors from the d-TGA Congenital Heart Surgeons' Society cohort (1985-1989) completed the SF-36 (2010) as a measure of FHS (n = 210; age 21-26 years). Patient characteristics, medical history, psychosocial factors, and previous adolescent CHQ-CF87 FHS assessment (2000) were explored for association with SF-36 domains, along with comparison with recent PedsQL data (2017)., Results: Patients scored themselves the same/higher than published normative data in 10 of 10 SF-36 summary scores/domains and similar in 5 of 6 PedsQL summary scores/domains. Factors commonly associated with lower summary scores/domains of the SF-36 were presence of cardiac symptoms, heart condition impacting physical activity/overall health/quality of life, unemployment, and lack of postsecondary education. Less commonly associated factors were lower birth weight, greater total medication number, female sex, shorter procedure-free interval, poor health knowledge, lower family income, younger age at SF-36, living with parents, and being married. These factors accounted for 17% to 47% of the variation in FHS summary scores/domains. FHS was minimally related to d-TGA morphology and repair type., Conclusions: Patients with d-TGA surviving into adulthood, regardless of morphology or repair type, can primarily expect normal FHS. Addressing the challenges of patients with d-TGA entering adulthood requires consideration of psychosocial factors and clinical management., (Copyright © 2019 The American Association for Thoracic Surgery.

- Abstract
Background: In addition to being associated with aortopathy, a bicuspid aortic valve (BAV) has been posed to be a risk factor for the dilation of the pulmonary autograft in the aortic position. The aim of this study is to assess the association between the subtype of native aortic valve leaflet fusion (right and noncoronary leaflets [R/N] vs right and left leaflets [R/L]) and autograft dilation and valve dysfunction after the Ross procedure., Methods: We performed a retrospective review of 43 patients with BAV who underwent a Ross procedure in our center from 1993 to 2013. Serial transthoracic echocardiography was used to measure changes in autograft and ascending aortic diameter over time. The aortic diameter was measured at four levels, and Z values were computed. Aortic dilation was defined as a Z value greater than 3., Results: The mean age at the time of the Ross procedure was 13.5 ± 9.2 years. R/L was the most prevalent native aortic valve subtype (R/L, n = 26, 61% vs R/N, n = 17, 39%). PreRoss procedure, aortic dilation was more frequent in patients with R/N fusion (P = .02), whereas the initial aortic valve gradient and grade of aortic insufficiency (AI) did not differ between the subgroups. At follow-up, (mean = 9.6 ± 4.3 years) dilation of the autograft and ascending aorta was seen more often in patients with R/N leaflet fusion (P = .03). Conversely, the prevalence of more than moderate AI was significantly higher in patients with R/L leaflet fusion (P = .03). There was no significant difference between groups among numbers of late reintervention on the aortic valve or root (P = .75); however the type of intervention varied by morphologic subtype. Patients with R/L fusion underwent more aortic valve replacements (AVRs) while patients with R/N fusion underwent more valve-sparing aortic root replacements., Conclusions: After Ross procedure, both groups of patients were likely to have a combination of dilation of the aortic root and the tubular portion of the ascending aorta at follow-up. Patients with R/L fusion were more likely to have a prevalence of root dilation, while patients with R/N fusion were more likely to have tubular ascending aorta dilation. The R/L phenotype is associated with a slightly more rapid dilation at follow-up and is more likely to have postoperative autograft insufficiency. This information may serve to guide patient and procedure selection for AVR., (© 2019 Wiley Periodicals, Inc.)

Tripathi S, Naevor AJ, Henrekin LL, and Welke KF
- Abstract
Objective: Most healthcare quality improvement projects focus on change management rather than the design of the process. In this article, we describe the development of a new rounding model based on quality function deployment, a Design for Six Sigma tool., Methods: We used affinity diagram, focus groups, and Kano analysis to identify critical customer requirements. We also used Kano analysis to determine the design team's ability to meet the requirements. We then completed a correlation matrix (House of Quality)., Results: Fifteen quality characteristics were analyzed on a correlation matrix to meet 15 demanded qualities. Numerical values were calculated based on the interactions identified by the design team. We designed a new rounding model based on the House of Quality; this new rounding model resulted in higher provider satisfaction (median 76-80%, P = 0.06)., Conclusions: We have described a sophisticated approach to the design of a new change strategy/intervention. This technique can be used as a starting point for other projects attempting to implement meaningful changes for complex processes of medical care., (Copyright © 2019 the Author(s).

- Abstract
Background: Several countries have regionalized congenital heart surgery (CHS). Before considering regionalization in the US, the current landscape must be understood. This investigation characterized the network of US hospitals providing CHS, including hospital locations and patient travel patterns., Methods: Patients ≤18 years undergoing CHS were identified in 2012 State Inpatient Databases from 39 states. Cases were stratified by the RACHS-1 method (high-risk defined as RACHS-1 categoris 4 to 6). Hospital and patient locations were identified. Patients were mapped to hospitals where they underwent surgery., Results: A total of 153 hospitals across 36 states performed ≥1 RACHS-1 case (19,064 operations). Of these, 101 hospitals (66%) were located within 25 miles of another hospital. Median annual RACHS-1 case volume was 90 (range, 1 to 797), with 55 hospitals performing ≤50 cases. A total of 111 hospitals (73%) performed ≥1 high-risk case. Of these, 39 (35%) performed ≤10 high-risk cases/year. Overall mortality rate was 3.5% (n = 666), with risk-adjusted mortality being lowest at hospitals in the highest-volume quartile (≥150 cases/year). About 25% of patients (n = 4,012) traveled >100 miles, with most traveling to hospitals within the highest-volume quartile; 53% of patients (n = 8,376) bypassed the nearest CHS hospital. Mortality was not associated with travel distance., Conclusions: We identified more US hospitals performing CHS than has been previously described. Many are small-volume and are in close proximity to one another. Patients are already traveling long distances to hospitals within the highest-volume quartile. These data help define the current landscape of CHS and associated considerations regarding regionalization., (Copyright © 2019 The Society of Thoracic Surgeons. Published by Elsevier Inc.

- Abstract
The purpose of public reporting is to provide transparency and accountability so that patients and their families can make informed choices. Our ability to assess and publicly report quality in congenital cardiac surgery is constrained by the available data and statistical techniques. Efforts should be directed toward collecting and evaluating information that provides a broad picture of what makes a high-quality program. For public reporting to succeed, the outcomes presented must be accessible, relevant, and understandable., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Tripathi S, Henrekin LL, Read CD, and Welke KF
- Abstract
Background: Pediatric cardiac intensive care unit rounds require high levels of efficiency in data transfer and decision making to achieve optimal performance. Traditional survey methods do not discriminate and prioritize effectively the elements of rounds essential to a provider. In this study, we describe our experience with a novel survey method (Kano analysis) to assess customers' (surgeons, intensivists, cardiologists, advanced practice nurses, and nurses) requirements from rounds., Methods: A 26-point survey divided into 3 domains (presentation, decision, and process elements) was conducted among Pediatric Intensive Care Unit (PICU) providers. Based on the survey, attractive, must be, performance, indifferent, and reverse categories were identified using methods described in the literature. Average satisfaction and dissatisfaction coefficients and percentages of attractive and mandatory elements in subgroups were compared. Results from the quantitative analysis were charted on a categorization plane., Results: The survey was returned by all providers with 96% valid responses. The highest satisfaction coefficient in the presentation domain was for "one line statement about the patient" (0.76), in the decision domain "rhythm/anti-arrhythmics" (0.54), and in the process domain "reformatting presentation script" (0.77). The highest dissatisfaction gradients were for "overnight events" (-0.91), "rhythm/anti-arrhythmics" (-0.71), and "asking families to join rounds" (-0.49). Among the 5 subgroups, surgeons required the largest percentage of items as mandatory or attractive and had the highest dissatisfaction coefficients in all 3 categories., Conclusion: Kano survey can provide rapid and precise actionable data to restructure a new process. Further research potentially also involving patients and families in the Kano survey may provide insight on patient-centered care models.

- Abstract
Background: The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database (ACSD) has been successfully linked to the Centers for Medicare and Medicaid (CMS) Medicare database, thereby facilitating comparative effectiveness research and providing information about long-term follow-up and cost. The present study uses this link to determine contemporary completeness, penetration, and representativeness of the STS ACSD., Methods: Using variables common to both STS and CMS databases, STS operations were linked to CMS data for all CMS coronary artery bypass graft (CABG) surgery hospitalizations discharged between 2000 and 2012, inclusive. For each CMS CABG hospitalization, it was determined whether a matching STS record existed., Results: Center-level penetration (number of CMS sites with at least one matched STS participant divided by the total number of CMS CABG sites) increased from 45% in 2000 to 90% in 2012. In 2012, 973 of 1,081 CMS CABG sites (90%) were linked to an STS site. Patient-level penetration (number of CMS CABG hospitalizations done at STS sites divided by the total number of CMS CABG hospitalizations) increased from 51% in 2000 to 94% in 2012. In 2012, 71,634 of 76,072 CMS CABG hospitalizations (94%) occurred at an STS site. Completeness of case inclusion at STS sites (number of CMS CABG cases at STS sites linked to STS records divided by the total number of CMS CABG cases at STS sites) increased from 88% in 2000 to 98% in 2012. In 2012, 69,213 of 70,932 CMS CABG hospitalizations at STS sites (98%) were linked to an STS record., Conclusions: Linkage of STS and CMS databases demonstrates high and increasing penetration and completeness of the STS database. Linking STS and CMS data facilitates studying long-term outcomes and costs of cardiothoracic surgery., (Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc.

- Abstract
Background: Previous composite performance measures of The Society of Thoracic Surgeons (STS) were estimated at the STS participant level, typically a hospital or group practice. The STS Quality Measurement Task Force has now developed a multiprocedural, multidimensional composite measure suitable for estimating the performance of individual surgeons., Methods: The development sample from the STS National Database included 621,489 isolated coronary artery bypass grafting procedures, isolated aortic valve replacement, aortic valve replacement plus coronary artery bypass grafting, mitral, or mitral plus coronary artery bypass grafting procedures performed by 2,286 surgeons between July 1, 2011, and June 30, 2014. Each surgeon's composite score combined their aggregate risk-adjusted mortality and major morbidity rates (each weighted inversely by their standard deviations) and reflected the proportion of case types they performed. Model parameters were estimated in a Bayesian framework. Composite star ratings were examined using 90%, 95%, or 98% Bayesian credible intervals. Measure reliability was estimated using various 3-year case thresholds., Results: The final composite measure was defined as 0.81 × (1 minus risk-standardized mortality rate) + 0.19 × (1 minus risk-standardized complication rate). Risk-adjusted mortality (median, 2.3%; interquartile range, 1.7% to 3.0%), morbidity (median, 13.7%; interquartile range, 10.8% to 17.1%), and composite scores (median, 95.4%; interquartile range, 94.4% to 96.3%) varied substantially across surgeons. Using 98% Bayesian credible intervals, there were 207 1-star (lower performance) surgeons (9.1%), 1,701 2-star (as-expected performance) surgeons (74.4%), and 378 3-star (higher performance) surgeons (16.5%). With an eligibility threshold of 100 cases over 3 years, measure reliability was 0.81., Conclusions: The STS has developed a multiprocedural composite measure suitable for evaluating performance at the individual surgeon level., (Copyright © 2015 The Society of Thoracic Surgeons.

- Abstract
Background: This study's objective was to develop a risk model incorporating procedure type and patient factors to be used for case-mix adjustment in the analysis of hospital-specific operative mortality rates after congenital cardiac operations., Methods: Included were patients of all ages undergoing cardiac operations, with or without cardiopulmonary bypass, at centers participating in The Society of Thoracic Surgeons Congenital Heart Surgery Database during January 1, 2010, to December 31, 2013. Excluded were isolated patent ductus arteriosus closures in patients weighing less than or equal to 2.5 kg, centers with more than 10% missing data, and patients with missing data for key variables. Data from the first 3.5 years were used for model development, and data from the last 0.5 year were used for assessing model discrimination and calibration. Potential risk factors were proposed based on expert consensus and selected after empirically comparing a variety of modeling options., Results: The study cohort included 52,224 patients from 86 centers with 1,931 deaths (3.7%). Covariates included in the model were primary procedure, age, weight, and 11 additional patient factors reflecting acuity status and comorbidities. The C statistic in the validation sample was 0.858. Plots of observed-vs-expected mortality rates revealed good calibration overall and within subgroups, except for a slight overestimation of risk in the highest decile of predicted risk. Removing patient preoperative factors from the model reduced the C statistic to 0.831 and affected the performance classification for 12 of 86 hospitals., Conclusions: The risk model is well suited to adjust for case mix in the analysis and reporting of hospital-specific mortality for congenital heart operations. Inclusion of patient factors added useful discriminatory power and reduced bias in the calculation of hospital-specific mortality metrics., (Copyright © 2015 The Society of Thoracic Surgeons.

- Abstract
Background: The empirically derived 2014 Society of Thoracic Surgeons Congenital Heart Surgery Database Mortality Risk Model incorporates adjustment for procedure type and patient-specific factors. The purpose of this report is to describe this model and its application in the assessment of variation in outcomes across centers., Methods: All index cardiac operations in The Society of Thoracic Surgeons Congenital Heart Surgery Database (January 1, 2010, to December 31, 2013) were eligible for inclusion. Isolated patent ductus arteriosus closures in patients weighing less than or equal to 2.5 kg were excluded, as were centers with more than 10% missing data and patients with missing data for key variables. The model includes the following covariates: primary procedure, age, any prior cardiovascular operation, any noncardiac abnormality, any chromosomal abnormality or syndrome, important preoperative factors (mechanical circulatory support, shock persisting at time of operation, mechanical ventilation, renal failure requiring dialysis or renal dysfunction (or both), and neurological deficit), any other preoperative factor, prematurity (neonates and infants), and weight (neonates and infants). Variation across centers was assessed. Centers for which the 95% confidence interval for the observed-to-expected mortality ratio does not include unity are identified as lower-performing or higher-performing programs with respect to operative mortality., Results: Included were 52,224 operations from 86 centers. Overall discharge mortality was 3.7% (1,931 of 52,224). Discharge mortality by age category was neonates, 10.1% (1,129 of 11,144); infants, 3.0% (564 of 18,554), children, 0.9% (167 of 18,407), and adults, 1.7% (71 of 4,119). For all patients, 12 of 86 centers (14%) were lower-performing programs, 67 (78%) were not outliers, and 7 (8%) were higher-performing programs., Conclusions: The 2014 Society of Thoracic Surgeons Congenital Heart Surgery Database Mortality Risk Model facilitates description of outcomes (mortality) adjusted for procedural and for patient-level factors. Identification of low-performing and high-performing programs may be useful in facilitating quality improvement efforts., (Copyright © 2015 The Society of Thoracic Surgeons.

- Abstract
Background and Aim of the Study: In patients undergoing the Ross procedure, the right ventricular outflow tract (RVOT) conduit is inserted in an orthotopic position rather than in the more heterotopic position used in the repair of complex congenital RVOT obstruction. The study aim was to compare the authors' institutional mid-term experience of large-sized homografts (>19 mm) in patients with Ross and non-Ross RVOT reconstructions., Methods: The outcome was reviewed of all homografts implanted for Ross (n = 72) or non-Ross (n = 64) RVOT reconstruction at a single center between 1993 and 2012. Echocardiographic data were reviewed to evaluate valve performance. Homograft dysfunction was defined as RVOT obstruction with peak echo-Doppler gradient >40 mmHg and/or grade >III/IV conduit valve regurgitation. Homograft failure was defined as the need for conduit replacement or catheter or surgical reintervention., Results: The age, body weight, conduit diameter and previous surgery were significantly higher in patients with Ross compared to the non-Ross group (p = 0.002, 0.003 and <0.001, respectively). The mean follow up duration was similar in both groups. There were 35 re-interventions (Ross, n = 17; non-Ross, n = 18). The data acquired showed actuarial survival, freedom from conduit dysfunction and conduit failure to be similar in both cohorts. Freedom from any type of reoperation was worse for the Ross group (58%) than for the non-Ross group (72%) (p = 0.05)., Conclusion: During the first 15 years after Ross or non-Ross pulmonary homograft implantation, the survival rate, freedom from failure and dysfunction, and RVOT gradient were statistically similar. Freedom from any type of reoperation was significantly higher in the non-Ross group, however.

- Abstract
Background: Dilation of the aorta is a frequent complication in patients with bicuspid aortic valves. The aim of this study was to determine the relationship between the subtype of leaflet fusion, right and noncoronary leaflet (R/N) fusion versus right and left leaflet (R/L) fusion, and the patterns of aortic dilation and valve dysfunction in young patients with bicuspid aortic valves., Methods: We performed a retrospective review of 642 patients who presented with bicuspid aortic valves between 1994 and 2014. Of these patients, 210 (33%) had aortic dilation (z score >3) by echocardiogram. For each patient, the most recent study or the last study before intervention was reviewed., Results: Median patient age was 15 years (range, 0 to 40 years) with patients with R/N fusion being younger. The most prevalent subtype was R/N fusion (R/N, n = 114, 54% versus R/L, n = 96, 46%). Dilation of the ascending aorta was seen more often in patients with R/N fusion (R/N, 88% versus R/L, 68%; p = 0.004), whereas the prevalence of dilation of the sinuses of Valsalva was significantly higher in patients with R/L fusion (R/L, 46% versus R/N, 20%; p = 0.01). The magnitude of dilation differed as well. The z value of the sinuses of Valsalva was significantly higher in patients with R/L fusion (R/L, 2.03 versus R/N, 1.2; p = 0.003), whereas the z values of the ascending aorta and sinotubular junction were similar between the groups. Patients with R/N fusion were more likely to have aortic stenosis, and within the R/N group, patients with aortic insufficiency had a greater degree of ascending aorta dilation (p = 0.04)., Conclusions: Our study suggests that in young patients with bicuspid aortic valves and aortic dilation, aortic valve morphology may be associated with the patterns of aortic dilation and valve dysfunction. Patients with R/N fusion were more likely to have ascending aorta dilation, whereas patients with R/L fusion were more likely to have dilation of the aortic root. In addition, patients with R/N fusion presented at a younger age and were more likely to have aortic stenosis. Recognition of these differences may eventually be helpful for patient counseling and the planning of follow-up., (Copyright © 2015 The Society of Thoracic Surgeons. Published by Elsevier Inc.

- Abstract
Background and Objectives: The use of pulse-oximetry screening to detect critical congenital heart defects in newborns has gained national and international momentum in the past decade. Our hospital system began screening in 2008. Since then, our program has undergone leadership changes and multiple quality improvement interventions. The aims of this study are to evaluate the evolution of our pulse-oximetry program and to provide insights from lessons learned over the course of a long-standing program., Methods: We reviewed 6 years of screening data and evaluated trends of missed screens, false-positives, protocol violations, and parental decline of screening. We implemented 3 quality improvement interventions (change in protocol, redesign of an electronic medical record documentation system to autocalculate results, and transition from research to standard-of-care) and reviewed the impact of a rigorous quality assurance review process. We used linear regression and statistical process control charts to evaluate the data., Results: A total of 18,363 newborns were screened; we identified 5 critical cases. We observed a significant decrease in missed (P < .001) and false-positive (P = .03) screens over time but found no significant trend in the rate of percentage of protocol violations (P = .26) or decline of screening (P = .99). Each metric showed behavior attributable to at least 1 quality improvement intervention., Conclusions: We established a sustainable pulse-oximetry screening program in our community hospital system, and the screening has now become routine. The quality of our screening was influenced by choice of screening protocol, rigor of quality assurance reviews, and the process used to interpret screening results., (Copyright © 2015 by the American Academy of Pediatrics.)

- Abstract
Background: The most common forms of risk adjustment for pediatric and congenital heart surgery used today are based mainly on the estimated risk of mortality of the primary procedure of the operation. The goals of this analysis were to assess the association of patient-specific preoperative factors with mortality and to determine which of these preoperative factors to include in future pediatric and congenital cardiac surgical risk models., Methods: All index cardiac operations in The Society of Thoracic Surgeons Congenital Heart Surgery Database (STS-CHSD) during 2010 through 2012 were eligible for inclusion. Patients weighing less than 2.5 kg undergoing patent ductus arteriosus closure were excluded. Centers with more than 10% missing data and patients with missing data for discharge mortality or other key variables were excluded. Rates of discharge mortality for patients with or without specific preoperative factors were assessed across age groups and were compared using Fisher's exact test., Results: In all, 25,476 operations were included (overall discharge mortality 3.7%, n=943). The prevalence of common preoperative factors and their associations with discharge mortality were determined. Associations of the following preoperative factors with discharge mortality were all highly significant (p<0.0001) for neonates, infants, and children: mechanical circulatory support, renal dysfunction, shock, and mechanical ventilation., Conclusions: Current STS-CHSD risk adjustment is based on estimated risk of mortality of the primary procedure of the operation as well as age, weight, and prematurity. The inclusion of additional patient-specific preoperative factors in risk models for pediatric and congenital cardiac surgery could lead to increased precision in predicting risk of operative mortality and comparison of observed to expected outcomes., (Copyright © 2014 The Society of Thoracic Surgeons.

- Abstract
Objectives: Tricuspid valve regurgitation (TR) is a common finding in children with hypoplastic left heart syndrome (HLHS) undergoing staged surgical reconstruction and can result from either abnormal valve morphology or incomplete leaflet coaptation due to annular dilatation. The purpose of this study was to determine the incidence of severe TR and to evaluate the effect of surgically treated tricuspid valve (TV) disease on overall survival., Methods: Between December 1988 and December 2012, 86 patients with HLHS underwent a Norwood procedure (mean age/weight, 11.1 days/3.5 kg). Thirty-five percent had associated congenital cardiac, structural, and genetic anomalies. Subsequently, 65 patients underwent a bidirectional Glenn procedure or a hemi-Fontan (stage II) and 42 patients a modified Fontan procedure (stage III). The mean follow-up was 6.6 years. All patients were evaluated preoperatively and postoperatively by Doppler echocardiography to determine the degree of TR., Results: At the time of discharge following the Norwood procedure, 64% (n = 47) of the patients had none/trivial, 32% (n = 24) had mild, 3% had moderate (n = 2), and 1% (n = 1) had severe TR on their post-Norwood Doppler echocardiograms. Among 74 Norwood survivors, 11 children (15%) with severe TR underwent TV repair at a median interval after the Norwood procedure of nine months (range, 2-70). There were one surgical and one late death, giving an overall mortality of 18%. The overall survival rate between TR and non-TR repair groups was not significantly different (p = 0.18). Four patients (36%) underwent reoperation for persistent TR., Conclusions: Severe TR as a risk factor for mortality in children undergoing palliative procedures for HLHS can be diminished by successful TV procedures. Survival at intermediate follow-up of patients with successful TV procedures that eliminate severe TR and patients without a history of severe TR are similar. Further follow-up is required to determine the impact of surgically treated TR on long-term survival and the durability of surgical techniques., (© 2014 Wiley Periodicals, Inc.)
