Comparing Consumer-Directed Hospital Rankings With STS Adult Cardiac Surgery Database Outcomes.

BACKGROUND: Public interest in stratifying hospital performance has led to the proliferation of commercial, consumer-oriented hospital rankings. In cardiac surgery, little is known about how these rankings correlate with clinical registry quality ratings. METHODS: The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database was queried for isolated coronary artery bypass grafting or coronary artery bypass grafting/valve patients at hospitals among the top 100 U.S. News & World Report (USNWR) Cardiology & Heart Surgery rankings from 2016 to 2020. Hospitals were grouped into deciles by risk-adjusted observed/expected (O/E) ratios for morbidity and mortality using the STS 2018 risk models. Agreement between STS Adult Cardiac Surgery Database and USNWR ranked deciles was calculated by Bowker symmetry test. The association between each center's annual change in STS O/E ratio and change in USNWR ranking was modeled in repeated measures regression analysis. RESULTS: Inclusion criteria were met by 524 393 patients from 149 hospitals that ranked in USNWR top 100 at least once during the study period. There was no agreement between USNWR ranking and STS major morbidity and mortality O/E ratio (P > .50 for all years). Analysis of patients undergoing surgery at the 65 hospitals that were consistently ranked in the top 100 during the study period demonstrated no association between annual change in hospital ranking and change in O/E ratio (P all > .3). CONCLUSIONS: There was no agreement between annual USNWR hospital ranking and corresponding risk-adjusted STS morbidity or mortality. Furthermore, annual changes in USNWR rankings could not be accounted for using clinical outcomes. These findings suggest that factors unrelated to key surgical outcomes may be driving consumer-directed rankings.

The Society of Thoracic Surgeons 2021 Adult Cardiac Surgery Risk Models for Multiple Valve Operations.

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.

Factors Associated With Successful Postoperative Day One Discharge After Anatomic Lung Resection.

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.

Readmission After Lobectomy for Lung Cancer: Not All Complications Contribute Equally.

OBJECTIVE: The aim of this study was to identify independent predictors of hospital readmission for patients undergoing lobectomy for lung cancer. SUMMARY BACKGROUND DATA: Hospital readmission after lobectomy is associated with increased mortality. Greater than 80% of the variability associated with readmission after surgery is at the patient level. This underscores the importance of using a data source that includes detailed clinical information. METHODS: Using the Society of Thoracic Surgeons (STS) General Thoracic Surgery Database (GTSD), we conducted a retrospective cohort study of patients undergoing elective lobectomy for lung cancer. Three separate multivariable logistic regression models were generated: the first included preoperative variables, the second added intraoperative variables, and the third added postoperative variables. The c statistic was calculated for each model. RESULTS: There were 39,734 patients from 277 centers. The 30-day readmission rate was 8.2% (n = 3237). In the final model, postoperative complications had the greatest effect on readmission. Pulmonary embolus {odds ratio [OR] 12.34 [95% confidence interval (CI),7.94-19.18]} and empyema, [OR 11.66 (95% CI, 7.31-18.63)] were associated with the greatest odds of readmission, followed by pleural effusion [OR 7.52 (95% CI, 6.01-9.41)], pneumothorax [OR 5.08 (95% CI, 4.16-6.20)], central neurologic event [OR 3.67 (95% CI, 2.23-6.04)], pneumonia [OR 3.13 (95% CI, 2.43-4.05)], and myocardial infarction [OR 3.16 (95% CI, 1.71-5.82)]. The c statistic for the final model was 0.736. CONCLUSIONS: Complications are the main driver of readmission after lobectomy for lung cancer. The highest risk was related to postoperative events requiring a procedure or medical therapy necessitating inpatient care.

Trends in the Surgical Treatment of Pseudotumor Cerebri Syndrome in the United States.

Importance: Optic nerve sheath fenestration (ONSF) and cerebrospinal fluid shunting are sometimes used to treat pseudotumor cerebri syndrome (PTCS), but their use patterns are unknown. Objectives: To investigate the frequency of surgical PTCS treatment in the United States and to compare patients undergoing ONSF with those treated with shunting. Design, Setting, and Participants: This was a retrospective longitudinal cross-sectional study. Inpatient data were obtained from the National Inpatient Sample (NIS), and outpatient surgical center data were obtained from the National Survey of Ambulatory Surgery (NSAS) and National Hospital Ambulatory Medical Care Survey (NHAMCS). Included in the analysis were 10 720 patients aged 18 to 65 years with a diagnosis code for PTCS, excluding venous thrombosis and other causes of intracranial hypertension. Time trends were explored and logistic regression was used to measure differences according to age, race/ethnicity, sex, Elixhauser comorbidity index, and other patient and hospital characteristics. Data analysis was performed from March 31 to October 7, 2020. Exposure: Treatment for PTCS, excluding venous thrombosis and other causes of intracranial hypertension. Main Outcomes and Measures: Annual number of PTCS-related admissions, ONSFs, and shunt procedures from 2002-2016. Patient and hospital-level characteristics of patients with PTCS undergoing ONSF or shunting were compared. Results: Between 2010 and 2016, 297 ONSFs were performed and 10 423 shunts were placed as treatment for PTCS. The procedures were most commonly performed in individuals aged 26 to 35 years (39.4%), and 9920 (92.4%) of the surgically treated patients were women. ONSF was more common among younger patients (eg, adjusted odds ratio [AOR] for patients ≥46 years vs those 18-25 years, 0.22; 95% CI, 0.08-0.61) and in Black, Hispanic, or other minority populations (AOR, 2.37; 95% CI, 1.31-4.30) and less common in the South (AOR, 0.34; 95% CI, 0.13-0.88) and West (AOR, 0.15; 95% CI, 0.04-0.58) compared with the Northeast. Total PTCS-related hospitalizations increased from 6081 (95% CI, 5137-7025) in 2002 to 18 020 (95% CI, 16 607-19 433) in 2016. Shunting increased from 2002 to 2011 and subsequently plateaued and declined. ONSF was used much less frequently, and use has not increased. No instances of outpatient ONSF or shunting for PTCS were recorded in the NSAS or NHAMCS databases. Conclusions and Relevance: This study's findings suggest that shunting is more common than ONSF and that the use gap has widened as shunting has increased. However, because overall PTCS-related hospitalizations have increased even more rapidly, the percentage of inpatients with PTCS undergoing surgery has decreased. These trends may reflect changes in medical treatment practices and outcomes or growing limitations in access to ophthalmic surgical expertise.

Self-reported vision and hallucinations in older adults: results from two longitudinal US health surveys.

BACKGROUND: Vision loss may be a risk factor for hallucinations, but this has not been studied at the population level. METHODS: To determine the association between self-reported vision loss and hallucinations in a large community-based sample of older adults, we performed a cross-sectional and longitudinal analysis of two large, nationally representative US health surveys: the National Health and Aging Trends Study (NHATS) and the Health and Retirement Study (HRS). Visual impairment and hallucinations were self- or proxy-reported. Multivariate single and mixed effects logistic regression models were built to examine whether visual impairment and history of cataract surgery were associated with hallucinations. RESULTS: In NHATS (n = 1520), hallucinations were more prevalent in those who reported difficulty reading newspaper print (OR 1.77, 95% confidence interval (CI): 1.32-2.39) or recognising someone across the street (OR 2.48, 95% CI: 1.86-3.31) after adjusting for confounders. In HRS (n = 3682), a similar association was observed for overall (OR 1.32, 95% CI: 1.08-1.60), distance (OR 1.61, 95% CI: 1.32-1.96) and near eyesight difficulties (OR 1.52, 95% CI: 1.25-1.85). In neither sample was there a significant association between cataract surgery and hallucinations after adjusting for covariates. CONCLUSIONS: Visual dysfunction is associated with increased odds of hallucinations in the older US adult population. This suggests that the prevention and treatment of vision loss may potentially reduce the prevalence of hallucinations in older adults.

Association of postoperative complications and outcomes following coronary artery bypass grafting.

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.

A contemporary analysis of goiters undergoing surgery in the United States.

INTRODUCTION: We identified disparities and at-risk populations among patients with goiters undergoing thyroidectomy. MATERIALS AND METHODS: The National Inpatient Sample (NIS) database was queried for patients with goiter who underwent thyroidectomy between 2009 and 2013. Multivariable logistic regression was used to determine factors associated with goiters undergoing thyroidectomy. RESULTS: The study consisted of 103,678 patients with thyroidectomy and a goiter diagnosis, which included: simple goiter (n = 7,692, 7.42%), nodular goiter (n = 73,524, 70.92%), thyrotoxicosis (n = 14,043, 13.54%), thyroiditis (n = 1,248, 1.20%), and thyroid cancer (n = 7,169, 6.92%). Factors associated with operation for simple goiter included age >65 years (AOR 1.43 [1.15-1.79]), black race (AOR 1.35 [1.14-1.58]), and being uninsured (AOR 2.13 [1.52-2.98]). Patients with cancerous goiters undergoing thyroidectomy were less likely to be Black (AOR 0.38 [0.31-0.48]) or uninsured (AOR 0.25 [0.07-0.89]). DISCUSSION: Understanding disparities within populations undergoing thyroidectomy for goiter may allow for targeted efforts to more effectively treat goiters nationwide.

Acute readmission following deep brain stimulation surgery for Parkinson's disease: A nationwide analysis.

INTRODUCTION: Deep brain stimulation (DBS) surgery is an efficacious, underutilized treatment for Parkinson's disease (PD). Studies of DBS post-operative outcomes are often restricted to data from a single center and consider DBS in isolation. National estimates of DBS readmission and post-operative outcomes are needed, as are comparisons to commonly performed surgeries. METHODS: This study used datasets from the 2013 and 2014 Nationwide Readmissions Database (NRD). Our sample was restricted to PD patients discharged alive after hospitalization for DBS surgery. Descriptive analyses examined patient, clinical, hospital and index hospitalization characteristics. The all-cause, non-elective 30-day readmission rate after DBS was calculated, and logistic regression models were built to examine factors associated with readmission. Readmission rates for the most common surgical procedures were calculated and compared to DBS. RESULTS: There were 6058 DBS surgeries for PD in our sample, most often involving a male aged 65 and older, who lived in a high socioeconomic status zip code. DBS patients had an average of four comorbidities. With respect to outcomes, the majority of patients were discharged home (95.3%). Non-elective readmission was rare (4.9%), and was associated with socioeconomic status, comorbidity burden, and teaching hospital status. Much higher acute, non-elective readmission rates were observed for common procedures such as upper gastrointestinal endoscopy (16.2%), colonoscopy (14.0%), and cardiac defibrillator and pacemaker procedures (11.1%). CONCLUSION: Short-term hospitalization outcomes after DBS are generally favorable. Socioeconomic disparities in DBS use persist. Additional efforts may be needed to improve provider referrals for and patient access to DBS.

Understanding nationwide readmissions after thyroid surgery.

BACKGROUND: The 30-day readmission rate is increasingly utilized as a metric of quality that impacts reimbursement. To date, there are no nationally representative data on readmission rates after thyroid surgery. We aimed to determine national readmission rates after inpatient thyroidectomy operations and whether select clinical factors were associated with increased odds of postthyroidectomy readmission. METHODS: Using the 2014 Nationwide Readmissions Database, we identified patients undergoing inpatient thyroid surgery as defined by the International Classification of Diseases, Ninth Revision, procedure codes for thyroid lobectomy, partial thyroidectomy, complete thyroidectomy, and substernal thyroidectomy. Descriptive statistics were used to report readmission rates, most common diagnosis and causes of readmission, and timing of presentation after discharge. Multivariable logistic regression models controlling for potential confounders were used to determine whether select factors were associated with 30-day readmission. RESULTS: A total of 22,654 patients underwent inpatient thyroid surgery during the study period, 990 of whom (4.4%) were readmitted within 30 days. Among these, the most common diagnoses during readmission were disorders of mineral metabolism and hypocalcemia, accounting for 36.0% and 26.6% of readmissions, respectively. This held true regardless of the apparent indication for thyroid surgery (goiter, cancer, or thyroid function disorder) or timing of readmission after discharge. Calcium-related abnormalities were the top diagnoses at readmissions (22.1%). Most readmissions (54.6%) occurred within 7 days of discharge, with 24.6% within the first 2 days Factors associated with an increased odds of readmission included having Medicare (adjusted odds ratio [AOR] 1.47 and 95% confidence interval [CI] 1.03-2.11) or Medicaid insurance (AOR 1.44 [CI 1.04-1.99]), being discharged to inpatient post acute care (AOR 2.31 [CI 1.48-3.62]) or to home health care (AOR 1.78 [CI 1.21-2.63]), having an Elixhauser comorbidity score ≥ 4 (AOR 2.04 [CI 1.27-3.26]), and a duration of stay ≥2 days after the thyroid surgery (AOR 2.7 [CI 1.9-3.82]). The only complication during index admission associated with increased odds of readmission was hypocalcemia (AOR 1.5 [CI 1.1-2.06]. Indications for thyroid surgery were not associated with increased odds of readmission. CONCLUSION: Readmissions after thyroid surgery are relatively low and occur early after surgery. The most common diagnoses identified on readmission were calcium and mineral metabolism disorders, which also were the most common cause of readmission. Socioeconomic factors, comorbidities, and complications during the index admissions were found to be associated with nonelective, postthyroidectomy readmissions. Recognition of these risk factors may guide the development of interventions and protocols to decrease readmissions.

A Study of Practice Behavior for Endotracheal Intubation Site for Children With Congenital Heart Disease Undergoing Surgery: Impact of Endotracheal Intubation Site on Perioperative Outcomes-An Analysis of the Society of Thoracic Surgeons Congenital Cardiac Anesthesia Society Database.

BACKGROUND: In adults undergoing cardiopulmonary bypass surgery, oral intubation is typically preferred over nasal intubation due to reduced risk of sinusitis and infection. In children, nasal intubation is more common and sometimes preferred due to perceived benefits of less postoperative sedation and a lower risk for accidental extubation. This study sought to describe the practice of nasal intubation in the pediatric population undergoing cardiopulmonary bypass surgery and assess the risks/benefits of a nasal route against an oral one. METHODS: Patients <18 years of age in the Society of Thoracic Surgeons Congenital Heart Surgery Database between January 2010 and December 2015 were included. Patients with a preoperative endotracheal tube, tracheostomy, or known airway anomalies were excluded. Multivariable modeling was used to assess the association between route of tracheal intubation and a composite measure of infection risk (wound infection, mediastinitis, septicemia, pneumonia, and endocarditis). Covariates were included to adjust for important patient characteristics (eg, weight, age, comorbidities), case complexity, and center effects. Secondary outcomes included length of intubation, hospital length of stay, and airway complications including accidental extubations. We also performed a subanalysis in children <12 months of age in high-volume centers (>100 cases/y) examining how infection risk may change with age at the time of surgery. RESULTS: Nasal intubation was used in 41% of operations in neonates, 38% in infants, 15% in school-aged children, and 2% in adolescents. Nasal intubation appeared protective for accidental extubation only in neonates (P = .02). Multivariable analysis in infants and neonates showed that the nasal route of intubation was not associated with the infection composite (relative risk [RR], 0.84; 95% CI, 0.59-1.18) or a shorter length of stay (RR, 0.992; 95% CI, 0.947-1.039), but was associated with a shorter intubation length (RR, 0.929; 95% CI, 0.869-0.992). Restricting to high-volume centers showed a significant interaction between age and intubation route with a risk change for infection occurring between approximately 6-12 months of age (P = .003). CONCLUSIONS: While older children undergoing nasal intubation trend similar to the adult population with an increased risk of infection, nasal intubation in neonates and infants does not appear to carry a similar risk. Nasal intubation in neonates and infants may also be associated with a shorter intubation length but not a shorter length of stay. Prospective studies are required to better understand these complex associations.

Contemporary Surgical Management of Hypertrophic Cardiomyopathy in the United States.

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 < 0.001, respectively). For patients with severe 3-4+ mitral regurgitation, SM alone was effective in reducing mitral regurgitation in 85.5% (355 of 415), and SM with MVr was effective in 88.0% (176 of 200; p = 0.4061). After risk adjustment, odds ratio for composite of mortality and major morbidity for group 2 versus group 1 was 1.8 (95% confidence interval: 1.4 to 2.4, p < 0.0001). 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.

Inpatient care for stiff person syndrome in the United States: a nationwide readmission study.

BACKGROUND: Stiff person syndrome (SPS) is a progressive neurological disorder characterized by axial muscle rigidity and involuntary spasms. Autoimmune and neoplastic diseases are associated with SPS. Our study objectives were to describe inpatient care for SPS in the United States and characterize 30-day readmissions. METHODS: We queried the 2014 Nationwide Readmission Database for hospitalizations where a diagnosis of SPS was recorded. For readmission analyses, we excluded encounters with missing length of stay, hospitalization deaths, and out-of-state and December discharges. National estimates of index hospitalizations and 30-day readmissions were computed using survey weighting methods. Unconditional logistic regression was used to examine associations between demographic, clinical, and hospital characteristics and readmission. RESULTS: There were 836 patients with a recorded diagnosis of SPS during a 2014 hospitalization. After exclusions, 703 patients remained, 9.4% of which were readmitted within 30 days. Frequent reasons for index hospitalization were SPS (27.8%) and diabetes with complications (5.1%). Similarly, readmissions were predominantly for diabetes complications (24.2%) and SPS. Most readmissions attributed to diabetes complications (87.5%) were to different hospitals. Female sex (OR, 3.29; CI: 1.22-8.87) and routine discharge (OR, 0.26; CI: 0.10-0.64) were associated with readmission, while routine discharge (OR, 0.18; CI: 0.04-0.89) and care at for-profit hospitals (OR, 10.87; CI: 2.03-58.25) were associated with readmission to a different hospital. CONCLUSIONS: Readmissions in SPS may result from disease complications or comorbid conditions. Readmissions to different hospitals may reflect specialty care, gaps in discharge planning, or medical emergencies. Studies are required to determine if readmissions in SPS are preventable.

Isolated Mitral Valve Surgery: The Society of Thoracic Surgeons Adult Cardiac Surgery Database Analysis.

BACKGROUND: 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. METHODS: 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). RESULTS: 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). CONCLUSIONS: 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.

Surgical Management and Outcomes of Ebstein Anomaly in Neonates and Infants: A Society of Thoracic Surgeons Congenital Heart Surgery Database Analysis.

BACKGROUND: Ebstein anomaly (EA) encompasses a broad spectrum of morphology and clinical presentation. Those who are symptomatic early in infancy are generally at highest risk, but there are limited data regarding multicentric practice patterns and outcomes. We analyzed multiinstitutional data concerning operations and outcomes in neonates and infants with EA. METHODS: Index operations reported in The Society of Thoracic Surgeons Congenital Heart Surgery Database (2010 to 2016) were potentially eligible for inclusion. Analysis was limited to patients with diagnosis of EA and less than 1 year of age at time of surgery (neonates ≤30 days, infants 31 to 365 days). RESULTS: The study population included 255 neonates and 239 infants (at 95 centers). Among neonates, median age at operation was 7 days (interquartile range, 4 to 13 days) and the majority required preoperative ventilation (61.6%, n = 157). The most common primary operation performed among neonates was Ebstein repair (39.6%, n = 101), followed by systemic-to-pulmonary shunt (20.4%, n = 52) and tricuspid valve closure (9.4%, n = 24). Overall neonatal operative mortality was 27.4% (n = 70), with composite morbidity-mortality of 51.4% (n = 48). For infants, median age at operation was 179 days (interquartile range, 108-234 days); the most common primary operation for infants was superior cavopulmonary anastomosis (38.1%, n = 91) followed by Ebstein repair (15.5%, n = 37). Overall operative mortality for infants was 9.2% (n = 22) with composite morbidity-mortality of 20.1% (48). CONCLUSIONS: Symptomatic EA in early infancy is very high risk and a variety of operative procedures were performed. A dedicated prospective study is required to more fully understand optimal selection of treatment pathways to guide a systematic approach to operative management.

The Incidence and Consequence of Prosthesis-Patient Mismatch After Surgical Aortic Valve Replacement.

BACKGROUND: 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. METHODS: 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. RESULTS: 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 (p < 0.001). The incidence of severe PPM decreased by 55% over the study period, from 13.8% in 2004 to 6.2% in 2014. CONCLUSIONS: 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.

Outcomes after coronary artery bypass grafting in patients with myocardial infarction, cardiogenic shock and unresponsive neurological state: analysis of the Society of Thoracic Surgeons Database.

OBJECTIVES: Previous studies have demonstrated a 20% mortality rate among patients undergoing isolated coronary artery bypass grafting (CABG) for cardiogenic shock. However, outcomes following CABG for cardiogenic shock in patients who are neurologically unresponsive preoperatively are unknown. METHODS: Utilizing the Society of Thoracic Surgeons Adult Cardiac Surgery Database between July 2011 and December 2013, patients undergoing urgent or emergent CABG within 7 days of an acute myocardial infarction complicated by cardiogenic shock were identified. Patients were stratified on the basis of whether they had a non-medically induced unresponsive state within 24 h of surgery. RESULTS: Of the 5259 patients with acute myocardial infarction complicated by cardiogenic shock who underwent CABG during the study period, 243 (4.62%) patients had an unresponsive preoperative neurological state. The unresponsive cohort had a higher 30-day operative mortality than the responsive cohort (33.74% vs 16.91%, P < 0.001). Unresponsive neurological state was associated with increased odds for mortality (adjusted odds ratio 1.81, 95% confidence interval 1.37-2.4; P < 0.001), postoperative stroke (adjusted odds ratio 2.17, 95% confidence interval 1.27-3.73; P = 0.0048) and encephalopathy (adjusted odds ratio 2.08, 95% confidence interval 1.44-3.01; P < 0.001). Among survivors in the unresponsive cohort, 78 (46.15%) were discharged home and 62 (36.69%) were discharged to extended care facilities. CONCLUSIONS: Although cardiac surgery in unresponsive patients in the setting of acute myocardial infarction complicated by cardiogenic shock is associated with considerable neurological disability and mortality, the majority survive to discharge. These findings may help guide patient and family discussions regarding goals of care.

Demographics, disparities, and outcomes in substernal goiters in the United States.

BACKGROUND: Disparities distinguishing patients with substernal goiters from nonsubsternal goiters have not been thoroughly described. METHODS: The National Inpatient Sample database was used to compare patients who underwent substernal thyroidectomy years 2000 to 2010 with those who underwent thyroidectomy for nonsubsternal goiter. RESULTS: A total of 110,889 patients underwent thyroidectomy for goiter (5,525 substernal and 105,364 nonsubsternal). Substernal thyroidectomy patients were older, more likely to be Black or Hispanic and to have Medicare insurance. They had a higher comorbidity index, were more likely to be admitted emergently and to have postoperative complications such as hemorrhage/hematoma, pneumothorax, pulmonary embolism, and hypocalcemia/hypoparathyroidism. Furthermore, substernal thyroidectomy patients had 73% increased odds of death during admission than nonsubsternal thyroidectomy patients. CONCLUSIONS: Substernal goiters present a distinct type of goiter with identifiable patient-level characteristics and an increased risk of postoperative complications and death. Earlier identification and treatment of goiters may allow earlier interventions at a stage when risks are reduced.

Trends in inpatient antiparkinson drug use in the USA, 2001-2012.

PURPOSE: Although therapeutic options and clinical guidelines for Parkinson's disease (PD) have changed significantly in the past 15 years, prescribing trends in the USA remain unknown. The purpose of this population-based cohort study was to examine patterns of inpatient antiparkinson drug use between January 2001 and December 2012 in relation to clinical guideline publication, drug introduction/withdrawal, and emerging safety concerns. METHODS: A total of 16,785 inpatients receiving pharmacological treatment for PD were identified in the Cerner Health Facts database. Our primary outcome was standardized (age, sex, race, and census region) annual prevalence of antiparkinson drug use. We also examined antiparkinson medication trends and polypharmacy by age and sex. RESULTS: The most frequently prescribed antiparkinson drugs between 2001 and 2012 were levodopa (85%) and dopamine agonists (28%). Dopamine agonist use began declining in 2007, from 34 to 27% in 2012. The decline followed publication of the American Academy of Neurology's practice parameter refuting levodopa toxicity, pergolide withdrawal, and pramipexole label revisions. Despite safety concerns for cognitive impairment and falls, individuals ≥80 years of age demonstrated stable rates of dopamine agonist use from 2001 to 2012. Polypharmacy was most common in younger patients. CONCLUSIONS: Dopamine agonist use declined from 2007 to 2012, suggesting that increased awareness of safety issues and practice guidelines influenced prescribing. These events appear to have minimally influenced treatment provided to older PD patients. Antiparkinson prescribing trends indicate that safety and best practice information may be communicated effectively.
