Clinical governance of patients with acute coronary syndromes.

AIMS: Using the principles of clinical governance, a patient-centred approach intended to promote holistic quality improvement, we designed a prospective, multicentre study in patients with acute coronary syndrome (ACS). We aimed to verify and quantify consecutive inclusion and describe relative and absolute effects of indicators of quality for diagnosis and therapy. METHODS AND RESULTS: Administrative codes for invasive coronary angiography and acute myocardial infarction were used to estimate the ACS universe. The ratio between the number of patients included and the estimated ACS universe was the consecutive index. Co-primary quality indicators were timely reperfusion in patients admitted with ST-elevation ACS and optimal medical therapy at discharge. Cox-proportional hazard models for 1-year death with admission and discharge-specific covariates quantified relative risk reductions and adjusted number needed to treat (NNT) absolute risk reductions. Hospital codes tested had a 99.5% sensitivity to identify ACS universe. We estimated that 7344 (95% CI: 6852-7867) ACS patients were admitted and 5107 were enrolled-i.e. a consecutive index of 69.6% (95% CI 64.9-74.5%), which varied from 30.7 to 79.2% across sites. Timely reperfusion was achieved in 22.4% (95% CI: 20.7-24.1%) of patients, was associated with an adjusted hazard ratio (HR) for 1-year death of 0.60 (95% CI: 0.40-0.89) and an adjusted NNT of 65 (95% CI: 44-250). Corresponding values for optimal medical therapy were 70.1% (95% CI: 68.7-71.4%), HR of 0.50 (95% CI: 0.38-0.66), and NNT of 98 (95% CI: 79-145). CONCLUSION: A comprehensive approach to quality for patients with ACS may promote equitable access of care and inform implementation of health care delivery.

Clinical governance programme in patients with acute coronary syndrome: design and methodology of a quality improvement initiative.

INTRODUCTION: Despite the availability of diverse evidence-based diagnostic and treatment options, many patients with acute coronary syndrome (ACS) still fail to receive effective, safe and timely diagnoses and therapies. The Association of Acute CardioVascular Care of the European Society of Cardiology has proposed and retrospectively validated a set of ACS-specific quality indicators. Combining these indicators with the principles of clinical governance-a holistic, patient-centred approach intended to promote continuous quality improvement-we designed the clinical governance programme in patients with ACS. METHODS AND ANALYSIS: This is a multicentre quality improvement initiative exploring multiple dimensions of care, including diagnosis, therapy, patient satisfaction, centre organisation and efficiency in all comers patients with ACS.The study will enrol ≈ 5000 patients prospectively (ie, at the time of the first objective qualifying ACS criterion) with a 1-year follow-up. Consecutive inclusion will be promoted by a simplified informed consent process and quantified by the concordance with corresponding hospital administrative records using diagnosis-related group codes of ACS.Coprimary outcome measures are (1) timely reperfusion in patients with ST-elevation ACS and (2) optimal medical therapy at discharge in patients with confirmed acute myocardial infarction. Secondary outcomes broadly include multiple indicators of the process of care. Clinical endpoints (ie, death, myocardial infarction, stroke and bleeding) will be adjudicated by a clinical event committee according to predefined criteria. ETHICS AND DISSEMINATION: The study has been approved by local ethics committee of all study sites. As a quality improvement initiative and to promote consecutive inclusion of the population of interest, a written informed consent will be requested only to patients who are discharged alive. Dissemination will be actively promoted by (1) the registration site (ClinicalTrials.Gov ID NCT04255537), (2) collaborations with investigators through open data access and sharing.

From research to clinical practice]. / Il rischio di sanguinamento nei pazienti con sindrome coronarica acuta trattati con farmaci antiaggreganti: incidenza, impatto prognostico e metodi di valutazione, dagli studi alla pratica clinica.

Dual antiplatelet therapy (DAPT) including aspirin and a P2Y12 inhibitor is the cornerstone for the treatment of patients with acute coronary syndrome (ACS). The introduction of more potent drugs significantly reduced ischemic events, but with an associated increased risk of bleeding. Although appropriate estimation of bleeding risk by comparing the single drugs is challenging, mainly because of differences in definitions, it has been consistently shown that bleeding events are associated with an adverse outcome, both at short and long-term follow-up.Current guidelines recommend a short DAPT in patients at high bleeding risk, making appropriate risk estimation of crucial importance. Several numerical scores have been proposed for use in daily clinical practice. Although an objective risk assessment provides superior risk discrimination compared to physician's estimation, none of these scores appear free from limitations, nor have been obtained from cohorts of patients on short-tern treatment with prasugrel or ticagrelor. In the present review, we report the rates of major bleeding observed in the main randomized clinical trials and registries, their association with mortality, differences in definitions when used as safety endpoint, and finally the scores currently used for evaluation in daily clinical practice.
