Association between public reporting of outcomes with procedural management and mortality for patients with acute myocardial infarction

Cardiac Catheterization Laboratory Management of the Comatose Adult Patient With an Out-of-Hospital Cardiac Arrest: A Scientific Statement From the American Heart Association

Out-of-hospital cardiac arrest is a leading cause of death, accounting for ≈50% of all cardiovascular deaths. The prognosis of such individuals is poor, with <10% surviving to hospital discharge. Survival with a favorable neurologic outcome is highest among individuals who present with a witnessed shockable rhythm, received bystander cardiopulmonary resuscitation, achieve return of spontaneous circulation within 15 minutes of arrest, and have evidence of ST-segment elevation on initial ECG after return of spontaneous circulation. The cardiac catheterization laboratory plays an important role in the coordinated Chain of Survival for patients with out-of-hospital cardiac arrest. The catheterization laboratory can be used to provide diagnostic, therapeutic, and resuscitative support after sudden cardiac arrest from many different cardiac causes, but it has a unique importance in the treatment of cardiac arrest resulting from underlying coronary artery disease. Over the past few years, numerous trials have clarified the role of the cardiac catheterization laboratory in the management of resuscitated patients or those with ongoing cardiac arrest. This scientific statement provides an update on the contemporary approach to managing resuscitated patients or those with ongoing cardiac arrest.

The France PCI registry: Design, methodology and key findings

BACKGROUND

Obstructive coronary artery disease is the main cause of death worldwide. By tracking events and gaining feedback on patient management, the most relevant information is provided to public health services to further improve prognosis.

AIMS

To create an inclusive and accurate registry of all percutaneous coronary intervention (PCI) procedures performed in France, to assess and improve the quality of care and create research incentives. Also, to describe the methodology of this French national registry of interventional cardiology, and present early key findings.

METHODS

The France PCI registry is a multicentre observational registry that includes consecutive patients undergoing coronary angiography and/or PCI. The registry was set up to provide online data analysis and structured reports of PCI activity, including process of care measures and assessment of risk-adjusted outcomes in all French PCI centres that are willing to participate. More than 150 baseline data items, describing demographic status, PCI indications and techniques, and in-hospital and 1-year outcomes, are captured into local reporting software by medical doctors and local research technicians, with subsequent encryption and internet transfer to central data servers. Annual activity reports and scoring tools available on the France PCI website enable users to benchmark and improve clinical practices. External validation and consistency assessments are performed, with feedback of data completeness to centres.

RESULTS

Between 01 January 2014 and 31 December 2022, participating centres increased from six to 47, and collected 364,770 invasive coronary angiograms and 176,030 PCIs, including 54,049 non-ST-segment elevation myocardial infarction cases and 31,631 ST-segment elevation myocardial infarction cases. Fifteen studies stemming from the France PCI registry have already been published.

CONCLUSIONS

This fully electronic, daily updated, high-quality, low-cost, national registry is sustainable, and is now expanding. Merging with medicoeconomic databases and nested randomized scientific studies are ongoing steps to expand its scientific potential.

Influence of Major Adverse Events on Procedural Selection for Percutaneous Coronary Intervention: Insights From the Veterans Affairs Clinical Assessment Reporting and Tracking Program

Background

Public reporting of percutaneous coronary intervention (PCI) outcomes has been associated with risk-averse attitudes, and pressure to avoid negative outcomes may hinder the care of high-risk patients referred for PCI in public reporting environments. It is unknown whether the occurrence of PCI-related major adverse events (MAEs) influences future case selection in nonpublic reporting environments. Here, we describe trends in PCI case selection among patients undergoing coronary angiography following MAEs in Veterans Affairs (VA) cardiac catheterization laboratories participating in a mandatory internal quality improvement program without public reporting of outcomes.

Methods

Patients who underwent coronary angiography between October 1, 2010, and September 30, 2018, were identified and stratified by VA 30-day PCI mortality risk. The association between MAEs and changes in the proportion of patients proceeding from coronary angiography to PCI within 14 days was assessed.

Results

A total of 251,526 patients and 913 MAEs were included in the analysis. For each prespecified time period of 1, 2, and 4 weeks following an MAE, there were no significant changes in the proportion of patients undergoing coronary angiography who proceeded to PCI within 14 days for the overall cohort and for each tercile of VA 30-day PCI mortality risk.

Conclusions

There were no deviations from routine PCI referral practices following MAEs in this analysis of VA cardiac catheterization laboratories. Nonpublic reporting environments and quality improvement programs may be influential in mitigating PCI risk-aversion behaviors.

Public Reporting on the Quality of Care in Patients with Acute Myocardial Infarction: The Korean Experience

Public reporting is a way to promote quality of healthcare. However, evidence supporting improved quality of care using public reporting in patients with acute myocardial infarction (AMI) is disputed. This study aims to describe the impact of public reporting of AMI care on hospital quality improvement in Korea. Patients with AMI admitted to the emergency room with ICD-10 codes of I21.0 to I21.9 as the primary or secondary diagnosis were identified from the national health insurance claims data (2007-2012). Between 2007 and 2012, 43,240/83,378 (51.9%) patients manifested ST segment elevation myocardial infarction (STEMI). Timely reperfusion rate increased (β = 2.78, p = 0.001). The mortality rate of STEMI patients was not changed (β = -0.0098, p = 0.384) but that of NSTEMI patients decreased (β = -0.465, p = 0.001). Public reporting has a substantial impact on the process indicators of AMI in Korea because of the increased reperfusion rate. However, the outcome indicators such as mortality did not significantly change, suggesting that public reporting did not necessarily improve the quality of care.

Contemporary Clinical and Coronary Anatomic Risk Model for 30-Day Mortality After Percutaneous Coronary Intervention

BACKGROUND

Percutaneous coronary intervention (PCI) procedures are increasing in clinical and anatomic complexity, likely increasing the calculated risk of mortality. There is need for a real-time risk prediction tool that includes clinical and coronary anatomic information that is integrated into the electronic medical record system.

METHODS

We assessed 70 503 PCIs performed in 73 Veterans Affairs hospitals from 2008 to 2019. We used regression and machine-learning strategies to develop a prediction model for 30-day mortality following PCI. We assessed model performance with and without inclusion of the Veterans Affairs SYNTAX score (Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery), an assessment of anatomic complexity. Finally, the discriminatory ability of the Veterans Affairs model was compared with the CathPCI mortality model.

RESULTS

The overall 30-day morality rate was 1.7%. The final model included 14 variables. Presentation status (salvage, emergent, urgent), ST-segment-elevation myocardial infarction, cardiogenic shock, age, congestive heart failure, prior valve disease, chronic kidney disease, chronic lung disease, atrial fibrillation, elevated international normalized ratio, and the Veterans Affairs SYNTAX score were all associated with increased risk of death, while increasing body mass index, hemoglobin level, and prior coronary artery bypass graft surgery were associated with lower risk of death. C-index for the development cohort was 0.93 (95% CI, 0.92-0.94) and for the 2019 validation cohort and the site validation cohort was 0.87 (95% CI, 0.83-0.92) and 0.86 (95% CI, 0.83-0.89), respectively. The positive likelihood ratio of predicting a mortality event in the top decile was 2.87% more accurate than the CathPCI mortality model. Inclusion of anatomic information in the model resulted in significant improvement in model performance (likelihood ratio test P<0.01).

CONCLUSIONS

This contemporary risk model accurately predicts 30-day post-PCI mortality using a combination of clinical and anatomic variables. This can be immediately implemented into clinical practice to promote personalized informed consent discussions and appropriate preparation for high-risk PCI cases.

Quality Improvement and Public Reporting in STEMI Care

Mortality rates for patients with ST-segment elevation myocardial infarction (STEMI) remain high despite development of novel drugs and interventions over the past several decades. There is significant variability between hospitals in use of evidence-based treatments, and substantial opportunities exist to optimize care pathways and reduce disparities in care delivery. Quality improvement interventions implemented at local, regional, and national levels have improved care processes and patient outcomes. This article reviews evidence for quality improvement interventions along the spectrum of STEMI care, describes existing systems for quality measurement, and examines local and national policy interventions, with special attention to public reporting programs.

Is a hospital quality policy based on a triad of accreditation, public reporting and inspection evidence-based? A narrative review

BACKGROUND

Since 2009, hospital quality policy in Flanders, Belgium, is built around a quality-of-care triad, which encompasses accreditation, public reporting (PR) and inspection. Policy makers are currently reflecting on the added value of this triad.

METHODS

We performed a narrative review of the literature published between 2009 and 2020 to examine the evidence base of the impact accreditation, PR and inspection, both individually and combined, has on patient processes and outcomes. The following patient outcomes were examined: mortality, length of stay, readmissions, patient satisfaction, adverse outcomes, failure to rescue, adherence to process measures and risk aversion. The impact of accreditation, PR and inspection on these outcomes was evaluated as either positive, neutral (i.e. no impact observed or mixed results reported) or negative.

OBJECTIVES

To assess the current evidence base on the impact of accreditation, PR and inspection on patient processes and outcomes.

RESULTS

We identified 69 studies, of which 40 were on accreditation, 24 on PR, three on inspection and two on accreditation and PR concomitantly. Identified studies reported primarily low-level evidence (level IV, n = 53) and were heterogeneous in terms of implemented programmes and patient populations (often narrow in PR research). Overall, a neutral categorization was determined in 30 articles for accreditation, 23 for PR and four for inspection. Ten of these recounted mixed results. For accreditation, a high number (n = 12) of positive research on adherence to process measures was discovered.

CONCLUSION

The individual impact of accreditation, PR and inspection, the core of Flemish hospital quality, was found to be limited on patient outcomes. Future studies should investigate the combined effect of multiple quality improvement strategies.

Assessment of repeat target lesion percutaneous coronary intervention as a quality measure for public reporting and general quality assessment for PCIs

BACKGROUND

Target lesion percutaneous coronary intervention (TLPCI) within 1 year of PCI has been proposed by critics of public reporting of short-term mortality as an alternative measure for PCI reporting.

METHODS

New York's PCI registry was used to identify 1-year repeat TLPCI and 1-year repeat TLPCI/mortality for patients discharged between December 1, 2013 and November 30, 2014. Significant independent predictors of the outcomes were identified. Hospital and cardiologist risk-adjusted outcomes were calculated, and outlier status and correlations of risk-adjusted rates were examined for the three outcomes.

RESULTS

The adverse outcome rates were 1.30, 4.21, and 8.97% for in-hospital/30-day mortality, 1-year repeat TLPCI, and 1-year repeat TLPCI/mortality. There were many commonalities but also many differences in significant predictors of the outcomes. Hospital and cardiologist risk-adjusted 1-year repeat TLPCI rates and repeat TLPCI/mortality rates were poorly correlated with risk-adjusted in-hospital/30-day mortality rates (eg, Spearman R = -.16 [p = .23] and .27 [p = .04], respectively, for hospital 1-year repeat TLPCI vs. in-hospital/30-day mortality). Many more providers were found to have significantly higher and lower rates for repeat TLPCI than for short-term mortality.

CONCLUSIONS

Hospital and cardiologist quality assessments are very different for TLPCI and repeat TLPCI/mortality than they are for short-term mortality. Repeat TLPCI/mortality rates are highly correlated with repeat TLPCI rates, but outlier providers differ. More study of repeat TLPCI and all the patient, cardiologist, and hospital factors associated with it may be required before using it as a supplement to, or in lieu of, short-term mortality in public reporting of PCI outcomes.

Public Reporting of Cardiac Outcomes for Patients With Acute Myocardial Infarction: A Systematic Review of the Evidence

BACKGROUND

Percutaneous coronary intervention (PCI) is recognized by both the American Heart Association and the American College of Cardiology as an optimal therapy to treat patients experiencing acute myocardial infarction (AMI) with ST-segment elevation myocardial infarction. A health policy aimed at improving outcomes for the patient with AMI is public reporting of whether a patient received a PCI.

OBJECTIVE

A systematic review was conducted to evaluate the effect of public reporting for patients with AMI, specifically for those patients who receive PCI.

METHODS

EMBASE, MEDLINE, Academic Search Premier, Google Scholar, and PubMed were searched from inception through August 2017. Articles were selected for inclusion if researchers evaluated public reporting and included an outcome for whether a patient received a PCI during hospitalization for an AMI. Methodological quality of the included studies was evaluated, and findings were synthesized.

RESULTS

Eight studies of high methodological quality were included in the review. Most studies found that, in areas of public reporting, patients were less likely to undergo a PCI and high-risk patients did not undergo a PCI. Researchers also found that patients with AMI had lower in-hospital mortality after the implementation of public reporting, but only if these patients received a PCI.

CONCLUSIONS

Although public reporting may have had intentions of improving care, there is strong evidence that this policy did not result in more timely PCIs or improved mortality of patients with AMI. In fact, public reporting resulted in unintended consequences of not providing care for the most vulnerable patients in fear of an adverse outcome.

Temporal changes in patient characteristics and outcomes in ST-segment elevation myocardial infarction 2003-2018

BACKGROUND

We sought to describe changes in demographic variables, process of care measures, and outcomes of patients treated in a regional ST-segment elevation myocardial infarction (STEMI) program over the last 15 years.

METHODS

We describe demographic variables, process of care measures, and outcomes of patients treated in the program in various 5-year time periods: 2003-2007 (n = 1,821), 2008-2012 (n = 1,968), and 2013-2018 (n = 2,223). The primary outcome measures were in-hospital and 30-day mortality.

RESULTS

Among 6,012 STEMI patients treated from 2003 to 2018 we observed a significant increase in mean age at presentation (62 ± 14 to 64 ± 13 years) and diabetes (14-22%, p < .01). The proportion of patients with cardiogenic shock (CS) and cardiac arrest (CA) pre-PCI increased significantly from 9.5% to 11.1% and 8.5% to 12.7% (p < .05), respectively. The median door-to-balloon (D2B) times decreased from 98 to 93 min and total ischemic time decreased from 202 to 185 min (all p < .05). Despite increased patient complexity, the proportion of nontransfer and transfer patients achieving D2B times consistent with guideline recommendations remained unchanged (for nontransfer patients 79-82%, p = .45 and for transfer patients 65-64%, p = .34). Among all STEMI patients, in-hospital mortality increased during the study period from 4.9 to 6.9% (p = .007) but remained stable (<2%) when CA and CS patients were excluded.

CONCLUSIONS

Over the last 15 years, short-term STEMI mortality has increased despite improvements in care delivery metrics. Patients with CA and/or CS now represent 10% of STEMI patients and are responsible for 80% of deaths. Therefore, efforts to improve STEMI mortality, and metrics for assessing STEMI programs, should focus on these patients.

Association between Public Reporting of Outcomes and the Use of Mechanical Circulatory Support in Patients with Cardiogenic Shock

Risk-averse behavior has been reported among physicians and facilities treating cardiogenic shock in states with public reporting. Our objective was to evaluate if public reporting leads to a lower use of mechanical circulatory support in cardiogenic shock. We conducted a retrospective study with the use of the National Inpatient Sample from 2005 to 2011. Hospitalizations of patients ≥18 years old with a diagnosis of cardiogenic shock were included. A regional comparison was performed to identify differences between reporting and nonreporting states. The main outcome of interest was the use of mechanical circulatory support. A total of 13043 hospitalizations for cardiogenic shock were identified of which 9664 occurred in reporting and 3379 in nonreporting states (age 69.9 ± 0.4 years, 56.8% men). Use of mechanical circulatory support was 32.8% in this high-risk population. Odds of receiving mechanical circulatory support were lower (OR 0.50; 95% CI 0.43-0.57; p < 0.01) and in-hospital mortality higher (OR 1.19; 95% CI 1.06-1.34; p < 0.01) in reporting states. Use of mechanical circulatory support was also lower in the subgroup of patients with acute myocardial infarction and cardiogenic shock in reporting states (OR 0.61; 95% CI 0.51-0.72; p < 0.01). In conclusion, patients with cardiogenic shock in reporting states are less likely to receive mechanical circulatory support than patients in nonreporting states.

Perceptions of Public and Nonpublic Reporting of Interventional Cardiology Outcomes and Its Impact on Practice: Insights From the Veterans Affairs Clinical Assessment, Reporting, and Tracking Program

Background

Physicians have expressed significant mistrust with public reporting of interventional cardiology outcomes. Similar data are not available on alternative reporting structures, including nonpublic quality improvement programs with internally distributed measures of interventional quality. We thus sought to evaluate the perceptions of public and nonpublic reporting of interventional cardiology outcomes and its impact on clinical practice.

Methods and Results

A standardized survey was distributed to 218 interventional cardiologists in the Veterans Affairs Healthcare System, with responses received from 62 (28%). The majority of respondents (90%) expressed some or a great deal of trust in the analytic methods used to generate reports in a nonpublic quality improvement system within Veterans Affairs, while a minority (35%) expressed similar trust in the analytic methods in a public reporting system that operates outside Veterans Affairs (P<0.001). Similarly, a minority of respondents (44%) felt that in‐hospital and 30‐day mortality accurately reflected interventional quality in a nonpublic quality improvement system, though a smaller proportion of survey participants (15%) felt that the same outcome reflected procedural quality in public reporting systems (P<0.001). Despite these sentiments, the majority of operators did not feel pressured to avoid (82% and 75%; P=0.383) or perform (72% and 63%; P=0.096) high‐risk procedures within or outside Veterans Affairs.

Conclusions

Interventional cardiologists express greater trust in analytic methods and clinical outcomes reported in a nonpublic quality improvement program than external public reporting environments. The majority of physicians did not feel pressured to avoid or perform high‐risk procedures, which may improve access to interventional care among high‐risk patients.

Association Between Current and Future Annual Hospital Percutaneous Coronary Intervention Mortality Rates

Importance

Multiple states publicly report a hospital's risk-adjusted mortality rate for percutaneous coronary intervention (PCI) as a quality measure. However, whether reported annual PCI mortality is associated with a hospital's future performance is unclear.

Objective

To evaluate the association between reported risk-adjusted hospital PCI-related mortality and a hospital's future PCI-related mortality.

Design, Setting, and Participants

This study used data from the New York Percutaneous Intervention Reporting System from January 1, 1998, to December 31, 2016, to assess hospitals that perform PCI.

Exposures

Public-reported, risk-adjusted, 30-day mortality after PCI.

Main Outcomes and Measures

The primary analysis evaluated the association between a hospital's reported risk-adjusted PCI-related mortality and future PCI-related mortality. The correlation between a hospital's observed to expected (O/E) PCI-related mortality rates each year and future O/E mortality ratios was assessed. Multivariable linear regression was used to examine the association between index year O/E mortality and O/E mortality in subsequent years while adjusting for PCI volume and patient severity.

Results

This study included 67 New York hospitals and 960 hospital-years. Hospitals with low PCI-related mortality (O/E mortality ratio, ≤1) and high mortality (O/E mortality ratio, >1) had inverse associations between their O/E mortality ratio in the index year and the subsequent change in the ratio (hospitals with low mortality, r = -0.45; hospitals with high mortality, r = -0.60). Little of the variation in risk-adjusted mortality was explained by prior performance. An increase in the O/E mortality ratio from 1.0 to 2.0 in the index year was associated with a higher O/E mortality ratio of only 0.15 (95% CI, 0.02-0.27) in the following year.

Conclusions and Relevance

At hospitals with high or low PCI-related mortality rates, the rates largely regressed to the mean the following year. A hospital's risk-adjusted mortality rate was poorly associated with its future mortality. The annual hospital PCI-related mortality may not be a reliable factor associated with hospital quality to consider in a practice change or when helping patients select high-quality hospitals.

Public Reporting of Percutaneous Coronary Intervention Outcomes: Moving Beyond the Status Quo

Importance

More than 20 years have passed since public reporting of percutaneous coronary intervention (PCI) outcomes first began in New York State, but reporting remains a polarizing issue.

Observations

Advocates of public reporting point to the strong incentive that public disclosure of outcomes data provides for institutions and clinicians to improve clinical care and to the importance of enabling patients to make informed choices about their care. Critics highlight the methodological challenges that impede fair and accurate assessments of care quality as well as reporting's unintended consequences. Public reporting of PCI outcomes has only been implemented in 5 states, but reporting efforts for multiple conditions and procedures are now proliferating nationally, propelled by the notion that transparency improves the quality of health care and fosters trust in health care institutions. Careful evaluation of the evidence to date for PCI in particular, however, suggests that enthusiasm for such efforts should be tempered.

Conclusions and Relevance

Public reporting has not achieved its primary objectives. Policy makers should consider variations of reporting that might strengthen care quality, empower patients, and mitigate undesirable repercussions.

A Survey of Interventional Cardiologists' Attitudes and Beliefs About Public Reporting of Percutaneous Coronary Intervention

Importance

Public reporting of procedural outcomes has been associated with lower rates of percutaneous coronary intervention (PCI) and worse outcomes after myocardial infarction. Contemporary data are limited on the influence of public reporting on interventional cardiologists' clinical decision making.

Objective

To survey a contemporary cohort of interventional cardiologists in Massachusetts and New York about how public reporting of PCI outcomes influences clinical decision making.

Design, Setting, and Participants

An online survey was developed with public reporting experts and administered electronically to eligible physicians in Massachusetts and New York who were identified by Doximity (an online physician networking site) and 2014 Medicare fee-for-service claims for PCI procedures. The personal and hospital characteristics of participants were ascertained via a comprehensive database from Doximity and the American Hospital Association annual surveys of US hospitals (2012 and 2013) and linked to survey responses. Associations between survey responses and characteristics of participants were evaluated in univariable and multivariable analyses.

Main Outcomes and Measures

Reported rate of avoidance of performing PCIs in high-risk patients and of perception of pressure from colleagues to avoid performing PCIs.

Results

Of the 456 physicians approached, 149 (32.7%) responded, including 67 of 129 (51.9%) in Massachusetts and 82 of 327 (25.1%) in New York. The mean (SD) age was 49 (9.2) years; 141 of 149 participants (94.6%) were men. Most participants reported practicing at medium to large, nonprofit hospitals with high-volume cardiac catheterization laboratories and cardiothoracic surgery capabilities. In 2014, participants had higher annual PCI volumes among Medicare patients than nonparticipants did (median, 31; interquartile range [IQR], 13-47 vs median, 17; IQR, 0-41; P < .001). Among participants, 65% reported avoiding PCIs on at least 2 occasions becase of concern that a bad outcome would negatively impact their publicly reported outcomes; 59% reported sometimes or often being pressured by colleagues to avoid performing PCIs because of a concern about the patient's risk of death. After multivariable adjustment, more years of experience practicing interventional cardiology was associated with lower odds of PCI avoidance. The state of practice was not associated with survey responses.

Conclusions and Relevance

Current PCI public reporting programs can foster risk-averse clinical practice patterns, which do not vary significantly between interventional cardiologists in New York and Massachusetts. Coordinated efforts by policy makers, health systems leadership, and the interventional cardiology community are needed to mitigate these unintended consequences.

The cardiac arrest survival score: A predictive algorithm for in-hospital mortality after out-of-hospital cardiac arrest

BACKGROUND

Out-of-hospital cardiac arrest (OHCA) is associated with high mortality. Current methods for predicting mortality post-arrest require data unavailable at the time of initial medical contact. We created and validated a risk prediction model for patients experiencing OHCA who achieved return of spontaneous circulation (ROSC) which relies only on objective information routinely obtained at first medical contact.

METHODS

We performed a retrospective evaluation of 14,892 OHCA patients in a large metropolitan cardiac arrest registry, of which 3952 patients had usable data. This population was divided into a derivation cohort (n = 2,635) and a verification cohort (n = 1,317) in a 2:1 ratio. Backward stepwise logistic regression was used to identify baseline factors independently associated with death after sustained ROSC in the derivation cohort. The cardiac arrest survival score (CASS) was created from the model and its association with in-hospital mortality was examined in both the derivation and verification cohorts.

RESULTS

Baseline characteristics of the derivation and verification cohorts were not different. The final CASS model included age >75 years (odds ratio [OR] = 1.61, confidence interval [CI][1.30-1.99], p < 0.001), unwitnessed arrest (OR = 1.95, CI[1.58-2.40], p < 0.001), home arrest (OR = 1.28, CI[1.07-1.53], p = 0.008), absence of bystander CPR (OR = 1.35, CI[1.12-1.64], p = 0.003), and non-shockable initial rhythm (OR = 3.81, CI[3.19-4.56], p < 0.001). The area under the curve for the model derivation and model verification cohorts were 0.7172 and 0.7081, respectively.

CONCLUSION

CASS accurately predicts mortality in OHCA patients. The model uses only binary, objective clinical data routinely obtained at first medical contact. Early risk stratification may allow identification of more patients in whom timely and aggressive invasive management may improve outcomes.

Invasive Management of Out of Hospital Cardiac Arrest

Out of hospital cardiac arrest (OHCA) is a major cause of morbidity and mortality worldwide. Clinical decision making is extremely difficult in this understudied patient population with high prevalence of neurological injury and inexorable shock states. As such, there are uncertain benefits from therapies available in the cardiac catheterization laboratory. Fear of futility and public reporting often affects decision making and can result in risk aversion. This review focuses on invasive management in OHCA care, with particular focus on coronary angiography, coronary revascularization, and mechanical support. Guidelines recommend emergency coronary angiography in patients with ST-segment elevations on ECG after OHCA, while the role of coronary angiography in patients without ST-segment elevations is less clear. Similar uncertainty remains in the appropriate revascularization strategy in these patients. As in other areas of cardiology, there is a growing interest in the role of mechanical circulatory support after OHCA, though the available literature shows mixed results. The many uncertainties associated with treating the patient with OHCA highlight the importance of clinical decision support tools and treatment algorithms in the care of this population. This review focuses on invasive management in OHCA care, with particular focus on coronary angiography, coronary revascularization, and mechanical support.

After COACT trial-new perspectives for the management of non-ST elevation myocardial infarction: early versus late cardiac catheterization post cardiac arrest

Out-of-hospital cardiac arrest (OHCA) is the leading cause of death in the United States, as 90% of them are fatal per the 2018 American Heart Association statistics. As many as fifty-percent of cardiac arrest events display an initial rhythm of pulseless ventricular tachycardia (pVT) and ventricular fibrillation (VF), and of those, coronary artery disease (CAD) is found in 60-80% of patients. Following return of spontaneous circulation, patients who present with ST-elevation myocardial infarction (STEMI) should undergo an early invasive strategy and primary intervention, which is well-established guideline-based management. The support of such a strategy in patients suspected to have underlying cardiac cause but without ST-elevation has been waxing and waning in the literature. The Coronary Angiography after Cardiac Arrest (COACT) trial was designed to compare survival between an immediate or delayed coronary angiography strategy in non-STEMI (NSTEMI) OHCA patients, following successful resuscitation. We present a systematic review of the history of management strategies in OHCA and propose guidelines to manage such patients in light of the COACT trial.

The association between the public reporting of individual operator outcomes with patient profiles, procedural management, and mortality after percutaneous coronary intervention: an observational study from the Pan-London PCI (BCIS) Registry using an interrupted time series analysis

AIMS

The public reporting of healthcare outcomes has a number of potential benefits; however, unintended consequences may limit its effectiveness as a quality improvement process. We aimed to assess whether the introduction of individual operator specific outcome reporting after percutaneous coronary intervention (PCI) in the UK was associated with a change in patient risk factor profiles, procedural management, or 30-day mortality outcomes in a large cohort of consecutive patients.

METHODS AND RESULTS

This was an observational cohort study of 123 780 consecutive PCI procedures from the Pan-London (UK) PCI registry, from January 2005 to December 2015. Outcomes were compared pre- (2005-11) and post- (2011-15) public reporting including the use of an interrupted time series analysis. Patients treated after public reporting was introduced were older and had more complex medical problems. Despite this, reported in-hospital major adverse cardiovascular and cerebrovascular events rates were significantly lower after the introduction of public reporting (2.3 vs. 2.7%, P < 0.0001). Interrupted time series analysis demonstrated evidence of a reduction in 30-day mortality rates after the introduction of public reporting, which was over and above the existing trend in mortality before the introduction of public outcome reporting (35% decrease relative risk 0.64, 95% confidence interval 0.55-0.77; P < 0.0001).

CONCLUSION

The introduction of public reporting has been associated with an improvement in outcomes after PCI in this data set, without evidence of risk-averse behaviour. However, the lower reported complication rates might suggest a change in operator behaviour and decision-making confirming the need for continued surveillance of the impact of public reporting on outcomes and operator behaviour.

The Impact of Public Performance Reporting on Market Share, Mortality, and Patient Mix Outcomes Associated With Coronary Artery Bypass Grafts and Percutaneous Coronary Interventions (2000-2016): A Systematic Review and Meta-Analysis

Supplemental Digital Content is available in the text.

Objective:

Public performance reporting (PPR) of coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI) outcomes aim to improve the quality of care in hospitals, surgeons and to inform consumer choice. Past CABG and PCI studies have showed mixed effects of PPR on quality and selection. The aim of this study was to undertake a systematic review and meta-analysis of the impact of PPR on market share, mortality, and patient mix outcomes associated with CABG and PCI.

Methods:

Six online databases and 8 previous reviews were searched for the period 2000–2016. Data extraction, quality assessment, systematic critical synthesis, and meta-analysis (where possible) were carried out on included studies.

Results:

In total, 22 relevant articles covering mortality (n=19), patient mix (n=14), and market share (n=6) outcomes were identified. Meta-analyses showed that PPR led to a near but not significant reduction in short-term mortality for both CABG and PCI. PPR on CABG showed a positive effect on market share for hospitals (3 of 6 studies) and low-performing surgeons (2 of 2 studies). Five of 6 PCI studies found that high-risk patients were less likely to be treated in States with PPR.

Conclusions:

There is some evidence that PPR reduces mortality rates in CABG/PCI-treated patients. The significance of there being no strong evidence, in the period 2000–2016, should be considered. There is need for both further development of PPR practice and further research into the intended and unintended consequences of PPR.

Effect of Public Reporting on the Utilization of Coronary Angiography After Out-of-Hospital Cardiac Arrest

BACKGROUND

Public reporting of cardiovascular outcomes has been associated with risk aversion for potentially lifesaving procedures and may have spillover effects on nonreported but related procedures.

METHODS AND RESULTS

A cross-sectional analysis of the utilization of coronary angiography among patients presenting with out-of-hospital cardiac arrest between 2005 and 2011 in states with public reporting of percutaneous coronary intervention outcomes (New York and Massachusetts) versus neighboring states without public reporting of percutaneous coronary intervention outcomes (Delaware, Connecticut, Maine, Vermont, Maryland, and Rhode Island) was performed using the Nationwide Inpatient Sample. We analyzed 50 125 admission records with out-of-hospital cardiac arrest between 2005 and 2011. The unadjusted rate of coronary angiography for patients presenting with out-of-hospital cardiac arrest in states with public reporting versus without public reporting was not different (20.8% versus 22.8%, P=0.35). We found no statistically significant difference in the adjusted likelihood of coronary angiography in states with public reporting, though the point estimate suggested decreased utilization (odds ratio, 0.84; 95% CI, 0.66-1.06; P=0.14). There was no difference in the adjusted likelihood of in-hospital mortality for patients presenting with out-of-hospital cardiac arrest in states with public reporting compared to states without public reporting (odds ratio, 0.98; 95% CI, 0.78-1.23; P=0.88).

CONCLUSIONS

Public reporting of percutaneous coronary intervention outcomes was associated with a nonstatistically significant reduction in the utilization of diagnostic coronary angiography, a nonreported but related procedure, for patients with out-of-hospital cardiac arrest.

Association of acute myocardial infarction cardiac arrest patient volume and in-hospital mortality in the United States: Insights from the National Cardiovascular Data Registry Acute Coronary Treatment And Intervention Outcomes Network Registry

BACKGROUND

Little is known about how differences in out of hospital cardiac arrest patient volume affect in-hospital myocardial infarction (MI) mortality.

HYPOTHESIS

Hospitals accepting cardiac arrest transfers will have increased hospital MI mortality.

METHODS

MI patients (ST elevation MI [STEMI] and non-ST elevation MI [NSTEMI]) in the Acute Coronary Treatment Intervention Outcomes Network Registry were included. Hospital variation of cardiac arrest and temporal trend of the proportion of cardiac arrest MI patients were explored. Hospitals were divided into tertiles based on the proportion of cardiac arrest MI patients, and association between in-hospital mortality and hospital tertiles of cardiac arrest was compared using logistic regression adjusting for case mix.

RESULTS

A total of 252 882 patients from 224 hospitals were included, of whom 9682 (3.8%) had cardiac arrest (1.6% of NSTEMI and 7.5% of STEMI patients). The proportion of MI patients who had cardiac arrest admitted to each hospital was relatively low (median 3.7% [25th, 75th percentiles: 3.0%, 4.5%]).with a range of 4.2% to 12.4% in the high-volume tertiles. Unadjusted in-hospital mortality increased with tertile: low 3.8%, intermediate 4.6%, and high 4.7% (P < 0.001); this was no longer significantly different after adjustment (intermediate vs high tertile odds ratio (OR) = 1.02; 95% confidence interval [0.90-1.16], low vs high tertile OR = 0.93 [0.83, 1.05]).

CONCLUSIONS

The proportion of MI patients who have cardiac arrest is low. In-hospital mortality among all MI patients did not differ significantly between hospitals that had increased proportions of cardiac arrest MI patients. For most hospitals, overall MI mortality is unlikely to be adversely affected by treating cardiac arrest patients with MI.

Current quality reporting methods are not adequate for salvage cardiac operations

OBJECTIVES

Outcomes in cardiac surgery are benchmarked against national Society of Thoracic Surgeons (STS) data and include patients undergoing elective, urgent, emergent, and salvage operations. This practice relies on accurate risk adjustment to avoid risk-averse behavior. We hypothesize that the STS risk calculator does not adequately characterize the risk of salvage operations because of their heterogeneity and infrequent occurrence.

METHODS

Data on all cardiac surgery patients with an STS predicted risk score (2002-2017) were extracted from a regional database of 19 cardiac surgery centers. Patients were stratified according to operative status for univariate analysis. Observed-to-expected (O:E) ratios for mortality and composite morbidity/mortality were calculated and compared among elective, urgent, emergent, and salvage patients.

RESULTS

A total of 76,498 patients met inclusion criteria. The O:E mortality ratios for elective, urgent, and emergent cases were 0.96, 0.98, and 0.93, respectively (all P values > .05). However, mortality rate was significantly higher than expected for salvage patients (O:E ratio, 1.41; P = .04). Composite morbidity/mortality rate was lower than expected in elective (O:E ratio, 0.81; P = .0001) and urgent (O:E ratio, 0.93; P = .0001) cases but higher for emergent (O:E ratio, 1.13; P = .0006) and salvage (O:E ratio, 1.24; P = .01). O:E ratios for salvage mortality were highly variable among each of the 19 centers.

CONCLUSIONS

The current STS risk models do not adequately predict outcomes for salvage cardiac surgery patients. On the basis of these results, we recommend more detailed reporting of salvage outcomes to avoid risk aversion in these potentially life-saving operations.

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.
