International comparison of acute myocardial infarction care and outcomes using quality indicators

Benchmarking System Monitoring on Quality Improvement in Percutaneous Coronary Intervention: A Nationwide Registry in Japan

Background

Quality indicators (QIs) have been developed to improve and standardize care quality in percutaneous coronary intervention (PCI). In Japan, consecutive PCI procedures are registered in a nationwide database (the Japanese Percutaneous Coronary Intervention registry), which introduces a benchmarking system for comparing individual institutional performance against the national average.

Objectives

The aim of this study was to assess the impact of the benchmarking system implementation on QI improvement at the hospital level.

Methods

A total of 734,264 PCIs were conducted at 1,194 institutions between January 2019 and December 2021. In January 2018, a web-based benchmarking system encompassing 7 QIs for PCI at the institutional level, including door-to-balloon time and rate of transradial intervention, was introduced. The process by which institutions tracked their QIs was centrally monitored.

Results

During the 3-year study period, the benchmarking system was reviewed at least once at 742 institutions (62.1%) (median 4 times; Q1-Q3: 2-7 times). The institutions that reviewed their records had higher PCI volumes. Among these institutions, although door-to-balloon time was not directly associated, the proportion of transradial intervention increased by 2.3% in the system review group during the initial year compared with 0.7% in their counterparts. However, in the subsequent year, the association between system reviews and QI improvement was attenuated.

Conclusions

The implementation of a benchmarking system, reviewed by participating institutions in Japan, was partially associated with improved QIs during the first year; however, this improvement was attenuated in the subsequent year, highlighting the need for further efforts to develop effective and sustainable interventions to enhance care quality in PCI.

Quality control to improve LDL-cholesterol management in patients with acute coronary syndromes based on the ACS EuroPath IV project

AIMS

We performed quality control of lipid-lowering therapy (LLT) in patients with acute coronary syndrome (ACS), with a view to proposing corrective actions.

METHODS AND RESULTS

Using a Define Measure Analysis Improve Control (DMAIC) approach applied to data from the ACS EuroPath IV survey, we measured attainment of two quality indicators (QIs) related to lipid-lowering treatment: (i) prescription of high-intensity statins (or equipotent treatment) before discharge, and (ii) proportion with LDL-cholesterol <55 mg/dL (1.4 mmol/L) during follow-up. A total of 530 European cardiologists responded and provided data for up to 5 patients from their centre, for acute and follow-up phases. Corrective measures are proposed to increase the rate of attainment of both QIs. Attainment of the first QI was measured in 929 acute-phase patients, 99% had LLT prescribed at discharge and 75% of patients fulfilled the first QI. Attainment of the second QI was assessed in 1721 patients with follow-up. The second QI was reached in 31% of patients. The DMAIC approach yielded 10 potential changes in prescription, 3 for the first and 7 for the second QI. The overall strategy is 'Fire to Target', i.e. early intensification of the LLT using statins, ezetimibe, bempedoic acid, and proprotein convertase subtilisin/kexin type-9 inhibitors, and is presented as an algorithm for routine application.

CONCLUSION

Quality control for LLT, based on the ACS EuroPath IV survey, detected 10 potential changes in prescription that could enhance attainment of 2 QIs. Whether the Fire to Target strategy will be adopted and effective needs to be assessed in further steps of the EuroPath Quality programme.

Cardiovascular disease care and outcomes in West and South European countries

Variations in cardiovascular disease (CVD) burden between West and South European countries are rarely reported. To address this knowledge gap, The Lancet Regional Health-Europe convened experts from a broad range of countries to assess the current state of knowledge of cardiovascular disease inequalities across Europe. This Review is specifically focused on West and South European countries. Mortality, risk factor and economic data for nine West European and six South European countries were sourced from the World Health Organisation, the Global Burden of Disease study and the World Bank. Healthcare data were collected by survey of participating countries. A key finding was of declines in age-standardised mortality rates (ASMRs) across all countries since 1990. In 2019 rates per 100,000 were lower in West European countries in males (279.7 (264.1-335.9) vs 337.2 (323.7-367.2)) and females (196.2 (183.3-228.8) vs 247.3 (232.2-268.3)). Differences in risk factor exposures were small, with the exception of physical activity and dietary factors, but across all countries the prevalence of obesity has increased, affecting >20% of adults in 2019. Healthcare delivery in 2019 showed inequalities with cardiovascular procedure rates lower in South compared with West European countries. Further declines in ASMRs in West and South European countries will require population strategies to reduce obesity and address inequalities in physical activity and dietary factors. Reducing the gap in procedure rates is unlikely to match the beneficial effects of population strategies for reducing CVD burden in South European countries.

Presentation, care, and outcomes of patients with NSTEMI according to World Bank country income classification: the ACVC-EAPCI EORP NSTEMI Registry of the European Society of Cardiology

BACKGROUND

The majority of NSTEMI burden resides outside high-income countries (HICs). We describe presentation, care, and outcomes of NSTEMI by country income classification.

METHODS AND RESULTS

Prospective cohort study including 2947 patients with NSTEMI from 287 centres in 59 countries, stratified by World Bank country income classification. Quality of care was evaluated based on 12 guideline-recommended care interventions. The all-or-none scoring composite performance measure was used to define receipt of optimal care. Outcomes included in-hospital acute heart failure, stroke/transient ischaemic attack, and death, and 30-day mortality. Patients admitted with NSTEMI in low to lower-middle-income countries (LLMICs), compared with patients in HICs, were younger, more commonly diabetic, and current smokers, but with a lower burden of other comorbidities, and 76.7% met very high risk criteria for an immediate invasive strategy. Invasive coronary angiography use increased with ascending income classification (LLMICs, 79.2%; upper middle income countries [UMICs], 83.7%; HICs, 91.0%), but overall care quality did not (≥80% of eligible interventions achieved: LLMICS, 64.8%; UMICs 69.6%; HICs 55.1%). Rates of acute heart failure (LLMICS, 21.3%; UMICs, 12.1%; HICs, 6.8%; P < 0.001), stroke/transient ischaemic attack (LLMICS: 2.5%; UMICs: 1.5%; HICs: 0.9%; P = 0.04), in-hospital mortality (LLMICS, 3.6%; UMICs: 2.8%; HICs: 1.0%; P < 0.001) and 30-day mortality (LLMICs, 4.9%; UMICs, 3.9%; HICs, 1.5%; P < 0.001) exhibited an inverse economic gradient.

CONCLUSION

Patients with NSTEMI in LLMICs present with fewer comorbidities but a more advanced stage of acute disease, and have worse outcomes compared with HICs. A cardiovascular health narrative is needed to address this inequity across economic boundaries.

Care of patients with ST-elevation myocardial infarction: an international analysis of quality indicators in the acute coronary syndrome STEMI Registry of the EURObservational Research Programme and ACVC and EAPCI Associations of the European Society of Cardiology in 11 462 patients

AIMS

To use quality indicators to study the management of ST-segment elevation myocardial infarction (STEMI) in different regions.

METHODS AND RESULTS

Prospective cohort study of STEMI within 24 h of symptom onset (11 462 patients, 196 centres, 26 European Society of Cardiology members, and 3 affiliated countries). The median delay between arrival at a percutaneous cardiovascular intervention (PCI) centre and primary PCI was 40 min (interquartile range 20-74) with 65.8% receiving PCI within guideline recommendation of 60 min. A third of patients (33.2%) required transfer from their initial hospital to one that could perform emergency PCI for whom only 27.2% were treated within the quality indicator recommendation of 120 min. Radial access was used in 56.6% of all primary PCI, but with large geographic variation, from 76.4 to 9.1%. Statins were prescribed at discharge to 98.7% of patients, with little geographic variation. Of patients with a history of heart failure or a documented left ventricular ejection fraction ≤40%, 84.0% were discharged on an angiotensin-converting enzyme inhibitor/angiotensin receptor blocker and 88.7% were discharged on beta-blockers.

CONCLUSION

Care for STEMI shows wide geographic variation in the receipt of timely primary PCI, and is in contrast with the more uniform delivery of guideline-recommended pharmacotherapies at time of hospital discharge.

Quality of acute myocardial infarction care in England and Wales during the COVID-19 pandemic: linked nationwide cohort study

BACKGROUND AND OBJECTIVE

The impact of the COVID-19 pandemic on the quality of care for patients with acute myocardial infarction (AMI) is uncertain. We aimed to compare quality of AMI care in England and Wales during and before the COVID-19 pandemic using the 2020 European Society of Cardiology Association for Acute Cardiovascular Care quality indicators (QIs) for AMI.

METHODS

Cohort study of linked data from the AMI and the percutaneous coronary intervention registries in England and Wales between 1 January 2017 and 27 May 2020 (representing 236 743 patients from 186 hospitals). At the patient level, the likelihood of attainment for each QI compared with pre COVID-19 was calculated using logistic regression. The date of the first national lockdown in England and Wales (23 March 2020) was chosen for time series comparisons.

RESULTS

There were 10 749 admissions with AMI after 23 March 2020. Compared with before the lockdown, patients admitted with AMI during the first wave had similar age (mean 68.0 vs 69.0 years), with no major differences in baseline characteristics (history of diabetes (25% vs 26%), renal failure (6.4% vs 6.9%), heart failure (5.8% vs 6.4%) and previous myocardial infarction (22.9% vs 23.7%)), and less frequently had high Global Registry of Acute Coronary Events risk scores (43.6% vs 48.6%). There was an improvement in attainment for 10 (62.5%) of the 16 measured QIs including a composite QI (43.8% to 45.2%, OR 1.06, 95% CI 1.02 to 1.10) during, compared with before, the lockdown.

CONCLUSION

During the first wave of the COVID-19 pandemic in England and Wales, quality of care for AMI as measured against international standards did not worsen, but improved modestly.

European Society of Cardiology methodology for the development of quality indicators for the quantification of cardiovascular care and outcomes

AIMS

It is increasingly recognized that tools are required for assessing and benchmarking quality of care in order to improve it. The European Society of Cardiology (ESC) is developing a suite of quality indicators (QIs) to evaluate cardiovascular care and support the delivery of evidence-based care. This paper describes the methodology used for their development.

METHODS AND RESULTS

We propose a four-step process for the development of the ESC QIs. For a specific clinical area with a gap in care delivery, the QI development process includes: (i) the identification of key domains of care by constructing a conceptual framework of care; (ii) the construction of candidate QIs by conducting a systematic review of the literature; (iii) the selection of a final set of QIs by obtaining expert opinions using the modified Delphi method; and (iv) the undertaking of a feasibility assessment by evaluating different ways of defining the QI specifications for the proposed data collection source. For each of the four steps, key methodological areas need to be addressed to inform the implementation process and avoid misinterpretation of the measurement results.

CONCLUSION

Detailing the methodology for the ESC QIs construction enables healthcare providers to develop valid and feasible metrics to measure and improve the quality of cardiovascular care. As such, high-quality evidence may be translated into clinical practice and the 'evidence-practice' gap closed.

Variations in Quality of Care by Sex and Social Determinants of Health Among Younger Adults With Acute Myocardial Infarction in the US and Canada

IMPORTANCE

Quality of care of young adults with acute myocardial infarction (AMI) may depend on health care systems in addition to individual-level factors such as biological sex and social determinants of health (SDOH).

OBJECTIVE

To examine whether the quality of in-hospital and postacute care among young adults with AMI differs between the US and Canada and whether female sex and adverse SDOH are associated with a low quality of care.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort analysis used data from 2 large cohorts of young adults (aged ≤55 years) receiving in-hospital and outpatient care for AMI at 127 centers in the US and Canada. Data were collected from August 21, 2008, to April 30, 2013, and analyzed from July 12, 2019, to March 10, 2021.

EXPOSURES

Sex, SDOH, and health care system.

MAIN OUTCOMES AND MEASURES

Opportunity-based quality-of-care score (QCS), determined by dividing the total number of quality indicators of care received by the total number for which the patient was eligible, with low quality of care defined as the lowest tertile of the QCS.

RESULTS

A total of 4048 adults with AMI (2345 women [57.9%]; median age, 49 [interquartile range, 44-52] years; 3004 [74.2%] in the US) were included in the analysis. Of 3416 patients with in-hospital QCS available, 1061 (31.1%) received a low QCS, including more women compared with men (725 of 2007 [36.1%] vs 336 of 1409 [23.8%]; P < .001) and more patients treated in the US vs Canada (962 of 2646 [36.4%] vs 99 of 770 [12.9%]; P < .001). Conversely, low quality of post-AMI care (748 of 2938 [25.5%]) was similarly observed for both sexes, with a higher prevalence in the US (678 of 2346 [28.9%] vs 70 of 592 [11.8%]). In adjusted analyses, female sex was not associated with low QCS for in-hospital (odds ratio [OR], 1.05; 95% CI, 0.87-1.28) and post-AMI (OR, 1.07; 95% CI, 0.88-1.30) care. Conversely, being treated in the US was associated with low in-hospital (OR, 2.93; 95% CI, 2.16-3.99) and post-AMI (OR, 2.67; 95% CI, 1.97-3.63) QCS, regardless of sex. Of all SDOH, only employment was associated with higher quality of in-hospital care (OR, 0.72; 95% CI, 0.59-0.88). Finally, only in the US, low quality of in-hospital care was associated with a higher 1-year cardiac readmissions rate (234 of 962 [24.3%]).

CONCLUSIONS AND RELEVANCE

These findings suggest that beyond sex, health care systems and SDOH that depict social vulnerability are associated with quality of AMI care. Taking into account SDOH among young adults with AMI may improve quality of care and reduce readmissions, especially in the US.

Impact of Race on the In-Hospital Quality of Care Among Young Adults With Acute Myocardial Infarction

Background The extent to which race influences in-hospital quality of care for young adults (≤55 years) with acute myocardial infarction (AMI) is largely unknown. We examined racial disparities in in-hospital quality of AMI care and their impact on 1-year cardiac readmission. Methods and Results We used data from the VIRGO (Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients) study enrolling young Black and White US adults with AMI (2008-2012). An in-hospital quality of care score (QCS) was computed (standard AMI quality indicators divided by the total a patient is eligible for). Multivariable logistic regression was performed to identify factors associated with the lowest QCS tertile, including interactions between race and social determinants of health. Among 2846 young adults with AMI (median 48 years [interquartile range 44-52], 67.4% women, 18.8% Black race), Black individuals, especially women, exhibited a higher prevalence of cardiac risk factors and social determinants of health and were more likely to experience a non-ST-segment-elevation myocardial infarction than White individuals. Black individuals were more likely in the lowest QCS tertile than White individuals (40.8% versus 34.7%; P=0.003). The association between Black race and low QCS (odds ratio [OR], 1.25; 95% CI, 1.02-1.54) was attenuated by adjustment for confounders. Employment was independently associated with better QCS, especially among Black participants (OR, 0.76; 95% CI, 0.62-0.92; P-interaction=0.02). Black individuals experienced a higher rate of 1-year cardiac readmission (29.9% versus 20.0%; P<0.0001). Conclusions Black individuals with AMI received lower in-hospital quality of care and exhibited a higher rate of cardiac readmissions than White individuals. Black individuals had a lower quality of care if unemployed, highlighting the intersection of race and social determinants of health.

Performance of acute coronary syndrome approaches in Brazil: a report from the BRACE (Brazilian Registry in Acute Coronary SyndromEs)

AIMS

Diagnostic and therapeutic tools have a significant impact on morbidity and mortality associated with acute coronary syndromes (ACS). Data about ACS performance measures are scarce in Brazil, and improving its collection is an objective of the Brazilian Registry in Acute Coronary syndromEs (BRACE).

METHODS AND RESULTS

The BRACE is a cross-sectional, observational epidemiological registry of ACS patients. Stratified 'cluster sampling' methodology was adopted to obtain a representative picture of ACS. A performance score (PS) varying from 0 to 100 was developed to compare studied parameters. Performance measures alone and the PS were compared between institutions, and the relationship between the PS and outcomes was evaluated. A total of 1150 patients, median age 63 years, 64% male, from 72 hospitals were included in the registry. The mean PS for the overall population was 65.9% ± 20.1%. Teaching institutions had a significantly higher PS (71.4% ± 16.9%) compared with non-teaching hospitals (63.4% ± 21%; P < 0.001). Overall in-hospital mortality was 5.2%, and the variables that correlated independently with in-hospital mortality included: PS-per point increase (OR = 0.97, 95% CI 0.95-0.98, P < 0.001), age-per year (OR = 1.06, 95% CI 1.03-1.09, P < 0.001), chronic kidney disease (OR = 3.12, 95% CI 1.08-9.00, P = 0.036), and prior angioplasty (OR = 0.25, 95% CI 0.07-0.84, P = 0.025).

CONCLUSIONS

In BRACE, the adoption of evidence-based therapies for ACS, as measured by the performance score, was independently associated with lower in-hospital mortality. The use of diagnostic tools and therapeutic approaches for the management of ACS is less than ideal in Brazil, with high variability especially among different regions of the country.

Assessment of the ESC quality indicators in patients with acute myocardial infarction: a systematic review

AIMS

To help improving quality of care in patients with acute myocardial infarction (AMI), the European Society of Cardiology (ESC) set 20 quality indicators (QIs). There is a need to compile and summarize QI availability, feasibility, and global compliance in real-world registries.

METHODS AND RESULTS

A systematic review of PubMed and Web of Science was conducted including all original articles reporting the use of the ESC QIs in AMI patients. Methods and reporting follow the guidelines of the PRISMA Statement and the protocol was registered in PROSPERO (CRD42020190541). Among the 220 screened citations, 9 studies met the inclusion criteria after full-text review. Among these 9 studies, there were 11 different cohorts. Patients were recruited from three different continents (31 countries). The number of QIs assessed ranged from 6 to 20, with 5 studies (56%) reporting data for at least 75% of the 20 QIs. There were room for improvement in terms of data availability (i.e. domain 6 measuring patient's satisfaction), feasibility (i.e. difficulties to find all data for composite QIs in domain 7), and attainment (i.e. high levels of compliance with the percentage of reperfused ST-segment elevation myocardial infarction patients, but low levels for a timely reperfusion).

CONCLUSIONS

Our systematic review has shown that it is possible to measure most QIs in existing registries, and that there is room for improvement in terms of data availability, feasibility, and levels of attainment to QIs. Our findings may influence the design of future registries to capture this information and help in QIs definition updates.

The 2020 ESC-ACVC quality indicators for the management of acute myocardial infarction applied to the FAST-MI registries

AIMS

We estimated the 2020 European Society of Cardiology-Acute Cardio Vascular Care (ESC-ACVC) quality indicators (QI) for the management of acute myocardial infarction, from three existing registries to determine the feasibility of assessment, room for improvement, association with outcomes, and suitability for centre benchmarking.

METHODS AND RESULTS

Data were extracted from three French nationwide registries, namely FAST-MI 2005, 2010, and 2015. Feasibility of assessment and room for improvement were estimated by the denominator (patients in whom QI could be measured) and numerator (patients who satisfied the QI, among those eligible). Associations between composite QIs (CQIs) and mortality were assessed by multivariate analysis. Centre benchmarking was based on the centres mean CQI, vs. the national mean. The 2020 QIs were measured in 12 660/13 130 patients from FAST-MI. Measurement feasibility ranged from 15% to 100% with greater potential for implementation with the 2020 QI set. The mean (±SD) value of the opportunity-based CQI was 0.72 ± 0.01 and attainment of the all-or-none CQI 8.5%. Both CQIs were associated with adjusted 1-year mortality. Centre categorization into low, intermediate, and high quality was feasible, and distinguished centres with differing mortality.

CONCLUSION

Most of the 2020 QI can be measured from existing registries in all domains but not in the patient's satisfaction domain. This assessment shows potential for implementation. Both CQIs were inversely associated with one-year mortality and centre benchmarking was feasible.

2020 Update of the quality indicators for acute myocardial infarction: a position paper of the Association for Acute Cardiovascular Care: the study group for quality indicators from the ACVC and the NSTE-ACS guideline group

AIMS

Quality indicators (QIs) are tools to improve the delivery of evidence-base medicine. In 2017, the European Society of Cardiology (ESC) Association for Acute Cardiovascular Care (ACVC) developed a set of QIs for acute myocardial infarction (AMI), which have been evaluated at national and international levels and across different populations. However, an update of these QIs is needed in light of the accumulated experience and the changes in the supporting evidence.

METHODS AND RESULTS

The ESC methodology for the QI development was used to update the 2017 ACVC QIs. We identified key domains of AMI care, conducted a literature review, developed a list of candidate QIs, and used a modified Delphi method to select the final set of indicators. The same seven domains of AMI care identified by the 2017 Study Group were retained for this update. For each domain, main and secondary QIs were developed reflecting the essential and complementary aspects of care, respectively. Overall, 26 QIs are proposed in this document, compared to 20 in the 2017 set. New QIs are proposed in this document (e.g. the centre use of high-sensitivity troponin), some were retained or modified (e.g. the in-hospital risk assessment), and others were retired in accordance with the changes in evidence [e.g. the proportion of patients with non-ST segment elevation myocardial infarction (NSTEMI) treated with fondaparinux] and the feasibility assessments (e.g. the proportion of patients with NSTEMI whom risk assessment is performed using the GRACE and CRUSADE risk scores).

CONCLUSION

Updated QIs for the management of AMI were developed according to contemporary knowledge and accumulated experience. These QIs may be applied to evaluate and improve the quality of AMI care.

Assessment of quality indicators for acute myocardial infarction management in 28 countries and use of composite quality indicators for benchmarking

Background:

The European Society of Cardiology established a set of quality indicators for the management of acute myocardial infarction. Our aim was to evaluate their degree of attainment, prognostic value and potential use for centre benchmarking in a large international cohort.

Methods:

Quality indicators were extracted from the long-tErm follow-uP of antithrombotic management patterns In acute CORonary syndrome patients (EPICOR) (555 hospitals, 20 countries in Europe and Latin America, 2010–2011) and EPICOR Asia (218 hospitals, eight countries, 2011–2012) registries, including non-ST-segment elevation acute myocardial infarction (n=6558) and ST-segment elevation acute myocardial infarction (n=11,559) hospital survivors. The association between implementation rates for each quality indicator and two-year adjusted mortality was evaluated using adjusted Cox models. Composite quality indicators were categorized for benchmarking assessment at different levels.

Results:

The degree of attainment of the 17 evaluated quality indicators ranged from 13% to 100%. Attainment of most individual quality indicators was associated with two-year survival. A higher compliance with composite quality indicators was associated with lower mortality at centre-, country- and region-level. Moreover, the higher the risk for two-year mortality, the lower the compliance with composite quality indicators.

Conclusions:

When EPICOR and EPICOR Asia were conducted, the European Society of Cardiology quality indicators would have been attained to a limited extent, suggesting wide room for improvement in the management of acute myocardial infarction patients. After adjustment for confounding, most quality indicators were associated with reduced two-year mortality and their prognostic value should receive further attention. The two composite quality indicators can be used as a tool for benchmarking either at centre-, country- or world region-level.
