Quality indicators for acute cardiovascular diseases: a scoping review

Quality indicators for the primary prevention of cardiovascular disease in primary care: A systematic review

BACKGROUND

Primary care is usually the entry point for preventing cardiovascular disease (CVD). Quality indicators can be used to assess and monitor the quality of care provided in a primary care setting. In this systematic review, we aimed to identify, summarise, and assess the methodological quality of indicators reported in the articles for the primary prevention of CVD in primary care.

METHODS

We searched Ovid MEDLINE, Ovid EMBASE, CINAHL Plus, SCOPUS, and grey literature for articles containing quality indicators published in English language. Quality indicators were categorised using the Donabedian framework: Structure (organisation of care), Process (assessment of metabolic risk factors, global risk assessment, lifestyle management, prescription of medications, risk communication/advice, referral), and Outcome (attainment of risk factor targets). Articles were reviewed by two authors, using the Appraisal of Indicators through Research and Evaluation (AIRE) instrument, where a score of ≥50% for each domain indicated strong methodological quality (e.g., stakeholder involvement).

RESULTS

We identified 282 articles for full-text review; 57 articles were included for extraction. A total of 726 (681 unique) quality indicators were extracted. Three out of four (76%) were process indicators (56 articles), followed by 15% outcome indicators (40 articles), and 9% structure indicators (12 articles). One-third of process indicators were related to the assessment of metabolic risk factors (222/726 indicators, 41 articles), followed by lifestyle management (153/726 indicators, 39 articles), prescription of medications (122/726 indicators, 37 articles), and global risk assessment (27/726, 14 articles). Few indicators were related to risk communication/advice (20/726 indicators, 7 articles) and referral (9/726 indicators, 6 articles). Only 26/57 (46%) articles were found to have strong methodological quality.

CONCLUSION

We summarised and appraised the methodological quality of indicators for the primary prevention of CVD. The next step requires prioritising a minimum set of quality indicators to encourage standardised collection and monitoring across countries.

Development and Validation of Quality Indicators for Pulmonary Arterial Hypertension Management in Japan: A Modified Delphi Consensus Study

BACKGROUND

Quality indicators (QIs) are used to standardize care and improve outcomes in patients with pulmonary arterial hypertension (PAH). It is important that QIs are validated within specific healthcare contexts. Therefore, this study aimed to validate QIs for PAH management in Japan using a modified Delphi consensus method.

METHODS

QI candidates were identified from published European QIs and clinical practice guidelines. An expert panel of 11 PAH specialists from diverse Japanese institutions anonymously rated the 36 initial QI candidates in two rounds using a nine-point appropriateness scale.

RESULTS

In the first round, 35 QIs received a median score of ≥7 points. A panel discussion was held between rounds to address the single low-scored QI, biomarker modifications, and invasive examinations, resulting in 36 modified QIs. In the second round, all modified QIs received median scores of ≥7 points and were judged to be valid as the final Japanese set of QIs.

CONCLUSIONS

The findings of this study validated a set of QIs for PAH management tailored to the Japanese healthcare context. These QIs can be used to standardize care, identify areas for improvement, and ultimately enhance outcomes for Japanese patients with PAH.

International Comparison of Quality Indicators for Adults Hospitalized for Heart Failure: A Systematic Review

BACKGROUND

There is limited international agreement on defining care quality for the millions of people hospitalized with heart failure worldwide. Our objective was to compare and measure agreement across existing internationally published quality indicators (QIs) for the care of adults hospitalized for heart failure.

METHODS

Systematic review and evidence gap map of internationally published articles reporting on QIs for adults hospitalized for heart failure, using PubMed, MEDLINE, EMBASE, and TRIP from inception to July 18, 2022. Narrative synthesis and descriptive statistics characterized included articles and QIs using the Donabedian Framework of Structural, Process, and Outcomes. The methodological quality of QI sets was assessed using the Appraisal of Indicators through Research and Evaluation instrument. Agreement about QIs was defined as having at least 3 different cardiovascular societies recommend its use. An evidence gap map displayed each QI according to its clinically relevant category, methodological quality, and reporting articles.

RESULTS

Fourteen articles from 11 societies reported 75 unique QIs; 53 QIs were process, 16 were structural, and 7 were outcome measures. There was limited agreement on individual QIs across sets as a minority were recommended by ≥3 societies (12%; 9/75 QIs). The most common QIs included postdischarge follow-up (73%, 8/11 societies), specific pharmacotherapy (64%, 7/11 societies), patient education (45%, 5/11 societies), assessment of left ventricular ejection fraction (45%, 5/11 societies), 30-day readmission rate (45%, 5/11 societies), cardiac rehabilitation (36%, 4/11 societies), and multidisciplinary management (27%, 3/11 societies).

CONCLUSIONS

There was little agreement on defining high-quality care and limited agreement on measures including postdischarge follow-up, specific pharmacotherapies, patient education, assessment of left ventricular ejection fraction, 30-day readmission, cardiac rehabilitation, and multidisciplinary management. These measures may define high-quality care and highlight opportunities to improve the quality of care for adults hospitalized for heart failure.

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.

Current status of real-world big data research in the cardiovascular field in Japan

Real-world data (RWD) are observational data obtained by collecting, structuring, and accumulating patient information among the medical big data. RWD are derived from a variety of patient medical care and health information outside of conventional research data, and include electronic health records, claims data, registry data of disease, drug and device, health check-up data, and more recently, patient information data from wearable devices. They are currently being utilized in various forms for optimal medical care and real-world evidence (RWE) is constructed through a process of hypothesis generation and verification based on the RWD research. Together with classic clinical research and pragmatic trials, RWE shapes the learning healthcare system and contributes to the improvement of medical care. In the cardiovascular medical care of the current super-aged society, the need for a variety of RWE and the research is increasing, since the guidelines established over time and the medical care based on it cannot necessarily be the best in accordance with the current medical situation. In this review, we focus on the RWD and RWE studies in the cardiovascular medical field and outlines their current status in Japan. Furthermore, we discuss the potential for extending the studies and issues related to the use of medical big data and RWD.

Hospital- and Patient-Level Analysis of Quality Indicators in Acute Coronary Syndrome Care: A Nationwide Database Study

BACKGROUND

This study aimed to clarify the variations in the quality of care provided to patients with acute coronary syndrome (ACS) and to investigate the association between quality of care and mortality at both hospital and patient levels with the use of a nationwide database.

METHODS

Patients with ACS who underwent percutaneous coronary intervention (PCI) from April 2014 to March 2018 were included from the National Database of Health Insurance Claims and Specific Health Checkups of Japan. Twelve quality indicators (QIs) available from administrative data and the association of the QIs with all-cause mortality were investigated.

RESULTS

From the analysis of 216,436 patients from 1215 hospitals, adherence to PCI on admission day, aspirin use on arrival, P2Y12 inhibitor use, and left ventricular function assessment were high (median proportion > 90%), and adherence to outpatient cardiac rehabilitation was low (median proportion < 10%). At the hospital level, acute-phase composite QI score was associated with reduced risk-adjusted 30-day mortality (β = -0.92 [95% confidence interval -1.19 to -0.65]; P < 0.001). At the patient level, all acute-phase and subacute-phase QIs were inversely associated with 30-day and 2-year mortalities, respectively (all P < 0.001).

CONCLUSIONS

Substantial variations in ACS care were observed in the current nationwide database. High adherence to the QI sets was associated with significant survival gains at both hospital and patient levels. Multilevel approach in QI assessment may be effective for improvement of survival in this population.
