Risk Aversion and Public Reporting. Part 1: Observations From Cardiac Surgery and Interventional Cardiology

Examining safety of cardiac surgery in patients with preoperative cardiac arrest

BACKGROUND

Although postoperative cardiac arrest is a well-studied complication of cardiac surgery, few guidelines exist regarding timing of surgery in preoperative cardiac arrest (pCA). We examined the association between delayed timing of operation and postoperative outcomes following cardiac surgery in a large cohort of pCA.

METHODS

Adults with a diagnosis of pCA undergoing a cardiac operation were identified in the 2016-2020 National Inpatient Sample. Those requiring surgery within 24 hours fo cardiac arrest were excluded. Patients who underwent a cardiac procedure after 5 days of cardiopulmonary resuscitation were classified as Delayed (others: Early). Multivariable regression models were constructed to evaluate associations between delayed timing of surgery with in-hospital mortality, postoperative complications, hospitalization duration, and costs.

RESULTS

Of an estimated 9,240 patients meeting study criteria, 4,860 (52.6%) received delayed cardiac surgery. Following entropy balancing, delayed surgery was significantly associated with decreased odds of in-hospital mortality (Adjusted Odds Ratio [AOR] 0.75, 95% Confidence Interval [CI] 0.58 - 0.97). However, delayed operation demonstrated greater odds of postoperative thromboembolic (AOR 1.44, 95% CI 1.02 - 2.04), and infectious (AOR 1.65, 95% CI 1.31 - 2.08) complications. Notably, delay did not alter odds of neurologic complication, and was linked to a decrement in per-day costs (β -$2,100, 95% CI -2,600 - -1,700).

CONCLUSIONS

While preoperative cardiac arrest remains challenging, the present study demonstrates the safety profile of delaying cardiac operation among patients tolerating at least 24 hours of a delay to surgery. Future studies are needed to elucidate the factors associated with favorable outcomes in this population.

Racial and Ethnic Disparities in Perioperative Health Care Among Patients Undergoing Cardiac Surgery: JACC State-of-the-Art Review

There has been little progress in reducing health care disparities since the 2003 landmark Institute of Medicine's report Unequal Treatment. Despite the higher burden of cardiovascular disease in underrepresented racial and ethnic groups, they have less access to cardiologists and cardiothoracic surgeons, and have higher rates of morbidity and mortality with cardiac surgical interventions. This review summarizes existing literature and highlights disparities in cardiovascular perioperative health care. We propose actionable solutions utilizing multidisciplinary perspectives from cardiology, cardiac surgery, cardiothoracic anesthesiology, critical care, medical ethics, and health disparity experts. Applying a health equity lens to multipronged interventions is necessary to eliminate the disparities in perioperative health care among patients undergoing cardiac surgery.

Public reporting for coronary artery bypass graft surgery: The quest for the optimal scorecard

OBJECTIVE

A number of publicly available rating algorithms are used to assess hospital performance in coronary artery bypass grafting (CABG). However, concerns remain that these algorithms fail to correlate with each other and inadequately capture the case complexity of individual center practices.

METHODS

Composite star ratings for isolated CABG from the Society of Thoracic Surgeons public reporting database were extracted for 2018-2019. U.S. News & World Report Best Hospitals was used to extract CABG ratings as well as overall cardiology and heart surgery ranking, and the Centers for Medicare & Medicaid Services Hospital Compare was used to extract CABG volume and 30-day mortality. Spearman correlation coefficients were used to assess possible relationships. Expert opinion on risk adjustment and program evaluation was incorporated.

RESULTS

Correlations between Society of Thoracic Surgeons star rating and U.S. News & World Report overall ranking in cardiology and heart surgery (r = 0.15) and Centers for Medicare & Medicaid Services 30-day mortality (r = -0.27) were poor. Society of Thoracic Surgeons star rating correlated weakly with U.S. News & World Report CABG ratings (r = 0.33) and with Centers for Medicare & Medicaid Services CABG volume (r = 0.32), whereas the latter 2 correlated moderately (r = 0.52) with each other. Of the 75 centers with accredited cardiac surgery training programs, 13 (17%) did not participate in Society of Thoracic Surgeons public reporting. Important gaps were identified in risk assessment, and potential solutions are proposed.

CONCLUSIONS

Correlations between current CABG public reporting systems are weak. Further work is needed to refine and standardize CABG rating systems to more adequately capture the scope and complexity of an individual center's clinical practice and to better inform patients.

Disparate Impacts of Two Public Reporting Initiatives on Clinical and Perceived Quality in Healthcare

Purpose

Transparency is increasingly viewed as a prerequisite for value-based health care that invites quality in the assessment of achieved value. However, nowadays the ability of transparency initiatives to enhance quality of care remains obscure, if not rejected. Thus, this study aims to investigate how transparency initiatives influence two types of quality of care: clinical and perceived quality.

Methods

First, factor analyses were conducted to construct three dependent variables: healthcare-associated infections (HAIs), 30-day readmission rates, and patient satisfaction. Then, the three quality models were compared by running ordinary least squares multiple regressions using STATA 14.1. The existence of heteroskedasticity was remedied by using robust standard errors.

Results

Examining general acute care hospitals in the US, the present study noted that the ability of public reporting to improve quality of care remains inconclusive and that the pursuit of transparency may lead to inadvertent results. The disclosure of all-payer claims data (APCD) was found to have the power to differentiate hospitals’ clinical and perceived quality, but it failed to reach the desired outcomes without market pressure. The impact of transparency on quality of care diverges depending on the unique characteristics of each transparency policy, even though they pursue the same ends through information dissemination. Furthermore, the same public policy showed starkly disparate impacts on clinical quality (eg, healthcare-associated infections (HAIs) and 30-day readmission rates) and perceived quality (eg, patient satisfaction).

Conclusion

Despite the theoretically acknowledged merits of transparency, the present study noted that its ability to enhance quality of care remains inconclusive, and the pursuit of transparency may even inadvertently harm quality of care. While hospitals may need to finetune their strategies for each quality measurement in order to cope with the new environmental pressure, it is health policymakers’ role to coordinate those quality metrics and improve the validity of patient experience measures and surveys.

Transparency, Public Reporting and a Culture of Change to Quality and Safety in Cardiac Surgery

Academic medical centers have a duty to serve as hospitals of last resort for advanced cardiac surgical care and therefore manage patients at elevated risk of post-operative morbidity and mortality. They must also meet state and professional quality targets devised to protect the public. The tension between these imperatives can be managed by a multi-dimensional quality improvement program which aims to manage risk, optimize outcomes and exclude futile operations. We here share our approach to this process, its impact on our institution and discuss pertinent issues relevant to institutions in a similar situation.

Operative mortality in adult cardiac surgery: is the currently utilized definition justified?

Background

This study evaluated operative mortalities following adult cardiac surgical operations to determine if this metric remains appropriate for the modern era.

Methods

This was a retrospective review of Society of Thoracic Surgeons (STS) indexed adult cardiac operations that included coronary artery bypass grafting (CABG), aortic valve replacement (AVR), CABG + AVR, mitral valve repair (MVr), CABG + MVr, mitral valve replacement (MVR) and CABG + MVR, performed at a single institution between 2011 and 2017. The primary outcome was the timing and relatedness of operation mortality, as defined by the STS as mortality within 30-day or during the index hospitalization, compared to the index operation. The secondary outcomes evaluated cause of death and the rates of postoperative complications.

Results

A total of 11,190 index cardiac operations were performed during the study period and operative mortality occurred in 246 (2.2%) of patients. The distribution of operative mortalities included 83.7% (n=206) who expired within 30-day while an inpatient, 6.9% (n=17) died within 30-day as an outpatient, 11.2% (n=23) expired after 30-day. The most common causes of operative mortality were cardiac (38.7%, n=92), renal failure (15.6%, n=37), and strokes (13.9%, n=33). Furthermore, 98.4% (n=242) of deaths were attributable to the index operation. Postoperative complications occurred frequently in those with operative mortality, with blood transfusions (80.1%), reoperations (65.0%) and prolonged ventilation (62.2%) being most common.

Conclusions

Most of the operative mortalities seemed to be attributable to the index cardiac operation. We believe that the current definition of mortality remains appropriate in the modern era.

The future of hospital quality of care policy: A multi-stakeholder discrete choice experiment in Flanders, Belgium

BACKGROUND

Collaboration between policymakers, patients and healthcare workers in hospital quality of care policy setting can improve the integration of new initiatives. The aim of this study was to quantify preferences for various characteristics of a future quality policy in a broad group of stakeholders.

MATERIALS AND METHODS

450 policymakers, clinicians, nurses, patient representatives and hospital board members in Flanders (Belgium) participated in five discrete choice experiments (DCE) on quality control, quality improvement, inspection, patient incidents and transparency. For each DCE, various attributes and levels were defined from a literature review and interviews with 12 international quality and patient safety experts.

RESULTS

For the attributes with the highest relative importance, participants exhibited a strong preference for quality control by an independent national organization and coordination of quality improvement initiatives at the level of hospital networks. The individual hospital was chosen over the government for setting up an action plan following patient complaints. Respondents also strongly preferred mandatory reporting of severe patient incidents and transparency by publicly reporting quality indicators at the hospital level.

CONCLUSIONS

A future quality model should focus on a multicomponent approach with external quality control, improvement actions on hospital network level and public transparency. DCEs provide an opportunity to incorporate the attitudes and views for individual components of a new policy recommendation.

Pharmacosurveillance in Juvenile Idiopathic Arthritis

The advent of biologic disease-modifying antirheumatic drugs targeting specific cytokines or cell-cell interactions has dramatically changed the outlook of patients with juvenile idiopathic arthritis. However, safety concerns remain around the use of therapeutic agents for children with juvenile idiopathic arthritis. Foremost among these are the risks of serious infections and malignancy. This article provides an overview of methodologies for pharmacosurveillance in juvenile idiopathic arthritis, including spontaneous reporting systems and the use of diverse data sources, such as electronic health records, administrative claims, and clinical registries. The risks of infections and malignancies are then briefly reviewed.

Variation in outcomes across surgeons meeting the Leapfrog volume standard for complex oncologic surgery

BACKGROUND

A large body of evidence supports regionalization of complex oncologic surgery to high-volume surgeons at high-volume hospitals. However, whether there is heterogeneity of outcomes among high-volume surgeons at high-volume hospitals remains unknown.

METHODS

Patients who underwent esophagectomy, lung resection, pancreatectomy, or proctectomy for primary cancer were identified within the Medicare 100% Standard Analytic File (2013-2017). Mixed-effects analyses assessed the association between Leapfrog annual volume standards for surgeons (esophagectomy ≥7, lung resection ≥15, pancreatectomy ≥10, proctectomy ≥6) and hospitals (esophagectomy ≥20, lung resection ≥40, pancreatectomy ≥20, proctectomy ≥16) relative to postoperative complications and 90-day mortality. Additional analyses using New York's all-payer Statewide Planning and Research Cooperative System (2004-2015) were performed.

RESULTS

Among 112,154 Medicare beneficiaries, high-volume surgeons at high-volume hospitals were associated with lower adjusted odds of complications (esophagectomy: odds ratio [OR], 0.73 [95% CI, 0.61-0.86]; lung resection: OR, 0.88 [95% CI, 0.82-0.94]; pancreatectomy: OR, 0.73 [95% CI, 0.66-0.80]; proctectomy: OR, 0.92 [95% CI, 0.85-0.99]) and 90-day mortality (esophagectomy: OR, 0.60 [95% CI, 0.44-0.76]; lung resection: OR, 0.82 [95% CI, 0.73-0.93]; pancreatectomy: OR, 0.66 [95% CI, 0.56-0.76]; proctectomy: OR, 0.74 [95% CI, 0.65-0.85]). For the average patient at the average high-volume hospital, there was a 2-fold difference in the adjusted complication rate between the best-performing and worst-performing high-volume surgeon for all operations (esophagectomy, 28%-55%; lung resection, 7%-21%; pancreatectomy, 16%-35%; proctectomy, 16%-28%). Wide variation was also present in adjusted 90-day mortality for esophagectomy (3.5%-9.3%). Results from New York's all-payer database were similar.

CONCLUSIONS

Even among high-volume surgeons meeting the Leapfrog volume standards, wide variation in postoperative outcomes exists. These findings suggest that volume alone should not be used as a quality indicator, and quality metrics should be continuously evaluated across all surgeons and hospital systems.

LAY SUMMARY

Previous studies have demonstrated a surgical volume-outcome relationship for high-risk operations-that is high-volume surgeons and hospitals that perform a specific surgical procedure more frequently have better outcomes for that operation. Although most high-volume surgeons had better outcomes, this study demonstrated that some high-volume surgeons did not have better outcomes. Therefore, volume is an important factor but should not be the only factor considered when assessing the quality of a surgeon and a hospital for cancer surgery.

Coronary Artery Bypass Grafting in Cardiogenic Shock: Decision-Making, Management Options, and Outcomes

Coronary artery bypass grafting is a highly efficacious mode of myocardial revascularization that reduces mortality from ischemic heart disease. The patient presenting after acute myocardial infarction in cardiogenic shock presents a unique challenge. Early revascularization is proven to reduce mortality, but many questions remain, including the optimal mode and extent of revascularization, the role of mechanical circulatory support, and which patients are candidates for surgical intervention. Unprecedented attention to the outcomes of cardiac surgery means decisions about the management of the acute myocardial infarction in cardiogenic shock patients are influenced by risk aversion. The authors here review this topic to arm the reader with a comprehensive understanding of the literature to better guide surgical decision-making and perioperative management.

The Society of Thoracic Surgeons Thoracic Surgery Practice and Access Task Force-2019 Workforce Report

BACKGROUND

The Society of Thoracic Surgeons (STS) has intermittently surveyed its workforce, providing isolated accounts of the current state of thoracic surgical practice.

METHODS

The 70-question survey instrument was received by 3834 STS surgeon members, and responses were gathered between September 16 and November 1, 2019. The return rate was 27.9%.

RESULTS

The median age of the active United States (US) thoracic surgeons is 56 years. Women comprise 8.4% of the responders, constituting 6.2% of adult cardiac, 10.6% of congenital heart, and 12.6% of general thoracic surgeons. Most practicing US surgeons (83.5%) graduated from medical school in the US. Survey respondents had 7 (21.8%), 8 (25.0%), 9 (22.1%) or 10 (29.2%) or more years of post-MD training before entering practice. Educational debt was increased compared with previous years, as were salaries. Overall career satisfaction was 54.1% (very or extremely satisfied), and overall average hours per week worked decreased compared with past surveys. However, 55.7% of surgeons had symptoms of burnout and depression. STS Database participation was high (90.5%), with the most common reason for not participating being cost (32.6%). Operative volume over the past 12 months decreased for 23.7% of surgeons. Of those who responded, 46.9% plan to retire between the age of 66 and 69 years and a further 25.6% at age 70 or older.

CONCLUSIONS

These data provide a current, detailed profile of the specialty. Ongoing challenges remain length of training and educational debt. Case volumes, scope of practice, and career satisfaction have remained relatively constant: however, symptoms of burnout or depression or both, are common.

Risk Aversion in Cardiac Surgery: 15-Year Trends in a Statewide Analysis

BACKGROUND

With a rising emphasis on public reporting, we hypothesized that select hospitals are becoming increasingly risk-averse by avoiding high-risk operations. Further, we evaluated the association between risk-averse practices, outcomes, and publicly reported quality measures.

METHODS

Clinical data from 78,417 patients undergoing cardiac surgery (2002-2016) from a regional consortium was paired with publicly available reimbursement and quality data. High-risk surgery was defined as predicted risk of mortality ≥5%. Hospital risk aversion was defined as a significant decrease in both high-risk volume and proportion, with cases stratified by hospital risk aversion status for univariate analysis.

RESULTS

The rate of high-risk cases decreased from 17.9% in 2002 to 12.6% in 2016. Significant risk aversion was seen in 39% of hospitals, which had a 59% decrease in high-risk volume vs a 16% decrease at non-risk-averse hospitals. In the last 5 years, declining high-risk cases at risk-averse hospitals were driven by fewer cases from transfers (19.2% vs 28.1%, P < .001) and the emergency department (17.6% vs 19.2%, P = .001). Only non-risk-averse hospitals had mortality rates lower than expected (risk-averse: 0.97 [95% confidence interval, 0.91-1.03], P = .30; non-risk-averse: 0.88 [95% confidence interval, 0.83-0.94], P = .001). There were no differences by risk aversion status in reported ratings or financial incentives (all P > .05).

CONCLUSIONS

Over 60% of hospitals continue to operate on high-risk patients, with concentration of care driven by transfer patterns. These non-risk-averse hospitals are high-performing with better-than-expected outcomes, particularly in high-risk cases. Transparency and objectivity in reporting are essential to ensure continued access for these high-risk patients.

Health Care Policy and Outcomes after Colon and Rectal Surgery: What Is the Bigger Picture?-Cost Containment, Incentivizing Value, Transparency, and Centers of Excellence

Early in the 21st century, the costs of health care in the United States have spiraled out of control, where the per capita spending is $9,237 per person-the highest in the world. By 2020, an estimated 20% of GDP will be spent on health care. The issue of cost and quality is now becoming a national crisis, with ∼50% of hospitals losing money on clinical operations, forcing closure of essential critical access hospitals, and forcing health care workers to relocate or change professions. This crisis will only worsen with the graying of America, as an estimated 17% of Americans will be over the age of 65 years by the year 2020. The policy and financial structures on which these changes are based are important factors of which practicing surgeons should be aware. This review discusses recent national health care policy reform and specific topics including cost-containment legislation, value-based incentives and penalties, transparency, and centers of excellence in colorectal surgery.

Quality metrics in coronary artery bypass grafting

Studies on the association between care quality, case volume, and outcomes in coronary artery bypass grafting (CABG) have concluded that consistent adherence to quality measures improves mortality rates and outcomes. However, the quality metrics are not well-defined, and their significance to surgeons and healthcare providers remains uncertain. We review the concept of "quality and quality metrics" and discuss their importance in the context of CABG.

Mandatory public reporting of cardiac surgery outcomes: The 2003 to 2014 Massachusetts experience

OBJECTIVES

Beginning in 2002, all 14 Massachusetts nonfederal cardiac surgery programs submitted Society of Thoracic Surgeons (STS) National Database data to the Massachusetts Data Analysis Center for mandatory state-based analysis and reporting, and to STS for nationally benchmarked analyses. We sought to determine whether longitudinal prevalences and trends in risk factors and observed and expected mortality differed between Massachusetts and the nation.

METHODS

We analyzed 2003 to 2014 expected (STS predicted risk of operative [in-hospital + 30-day] mortality), observed, and risk-standardized isolated coronary artery bypass graft mortality using Massachusetts STS data (N = 39,400 cases) and national STS data (N = 1,815,234 cases). Analyses included percentage shares of total Massachusetts coronary artery bypass graft volume and expected mortality rates of 2 hospitals before and after outlier designation.

RESULTS

Massachusetts patients had significantly higher odds of diabetes, peripheral vascular disease, low ejection fraction, and age ≥75 years relative to national data and lower odds of shock (odds ratio, 0.66; 99% confidence interval, 0.53-0.83), emergency (odds ratio, 0.57, 99% confidence interval, 0.52-0.61), reoperation, chronic lung disease, dialysis, obesity, and female sex. STS predicted risk of operative [in-hospital + 30-day] mortality for Massachusetts patients was higher than national rates during 2003 to 2007 (P < .001) and no different during 2008 to 2014 (P = .135). Adjusting for STS predicted risk of operative [in-hospital + 30-day] mortality, Massachusetts patients had significantly lower odds (odds ratio, 0.79; 99% confidence interval, 0.66-0.96) of 30-day mortality relative to national data. Outlier programs experienced inconsistent, transient influences on expected mortality and their percentage shares of Massachusetts coronary artery bypass graft cases.

CONCLUSIONS

During 12 years of mandatory public reporting, Massachusetts risk-standardized coronary artery bypass graft mortality was consistently and significantly lower than national rates, expected rates were comparable or higher, and evidence for risk aversion was conflicting and inconclusive.

Myocardial revascularization: the evolution of the STS database and quality measurement for improvement

The Society of Thoracic Surgeons (STS) is a not-for-profit organization dedicated to helping clinicians and researchers provide optimal outcomes for patients undergoing heart, lung, and esophageal surgery. The organization was founded in 1964 and has grown to now include over 7300 members in over 90 countries. The STS created a national database that collects detailed clinical information on patients undergoing adult cardiac, pediatric and congenital cardiac, and general thoracic operations. The data collected are used to produce risk-adjusted, nationally benchmarked performance assessments and feedback; facilitate voluntary public reporting; support quality initiatives; develop evidence-based guidelines; monitor long-term clinical outcomes; track device performance; and promote high-quality research collaboratives.

Beyond borders-international database collaboration in thoracic surgery

Thoracic surgery databases continue to emerge as pillars for institutional quality improvement and research endeavors. This paper reviews the current state of the largest thoracic surgery databases: the Thoracic Surgeons General Thoracic Surgery Database (STS-GTSD) and the European Society of Thoracic Surgery Database (ESTSD). In addition, we utilize these as a platform to evaluate the role and key ingredients for successful international database collaborations. Ultimately, collaborative efforts among large databases unify research efforts, foster cohesion, serve as benchmarks for quality improvement locally, nationally and internationally, promote comparative innovation, and ultimately improve patient outcomes.

Impact of public release of performance data on the behaviour of healthcare consumers and providers

BACKGROUND

It is becoming increasingly common to publish information about the quality and performance of healthcare organisations and individual professionals. However, we do not know how this information is used, or the extent to which such reporting leads to quality improvement by changing the behaviour of healthcare consumers, providers, and purchasers.

OBJECTIVES

To estimate the effects of public release of performance data, from any source, on changing the healthcare utilisation behaviour of healthcare consumers, providers (professionals and organisations), and purchasers of care. In addition, we sought to estimate the effects on healthcare provider performance, patient outcomes, and staff morale.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, and two trials registers on 26 June 2017. We checked reference lists of all included studies to identify additional studies.

SELECTION CRITERIA

We searched for randomised or non-randomised trials, interrupted time series, and controlled before-after studies of the effects of publicly releasing data regarding any aspect of the performance of healthcare organisations or professionals. Each study had to report at least one main outcome related to selecting or changing care.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened studies for eligibility and extracted data. For each study, we extracted data about the target groups (healthcare consumers, healthcare providers, and healthcare purchasers), performance data, main outcomes (choice of healthcare provider, and improvement by means of changes in care), and other outcomes (awareness, attitude, knowledge of performance data, and costs). Given the substantial degree of clinical and methodological heterogeneity between the studies, we presented the findings for each policy in a structured format, but did not undertake a meta-analysis.

MAIN RESULTS

We included 12 studies that analysed data from more than 7570 providers (e.g. professionals and organisations), and a further 3,333,386 clinical encounters (e.g. patient referrals, prescriptions). We included four cluster-randomised trials, one cluster-non-randomised trial, six interrupted time series studies, and one controlled before-after study. Eight studies were undertaken in the USA, and one each in Canada, Korea, China, and The Netherlands. Four studies examined the effect of public release of performance data on consumer healthcare choices, and four on improving quality.There was low-certainty evidence that public release of performance data may make little or no difference to long-term healthcare utilisation by healthcare consumers (3 studies; 18,294 insurance plan beneficiaries), or providers (4 studies; 3,000,000 births, and 67 healthcare providers), or to provider performance (1 study; 82 providers). However, there was also low-certainty evidence to suggest that public release of performance data may slightly improve some patient outcomes (5 studies, 315,092 hospitalisations, and 7502 providers). There was low-certainty evidence from a single study to suggest that public release of performance data may have differential effects on disadvantaged populations. There was no evidence about effects on healthcare utilisation decisions by purchasers, or adverse effects.

AUTHORS' CONCLUSIONS

The existing evidence base is inadequate to directly inform policy and practice. Further studies should consider whether public release of performance data can improve patient outcomes, as well as healthcare processes.
