Benchmarking as a quality of care improvement tool for patients with ST-elevation myocardial infarction: an NCDR ACTION Registry experience in Latin America

Characteristics of High-Performing Hospitals in Cardiogenic Shock Following Acute Myocardial Infarction

Cardiogenic shock after acute myocardial infarction (AMI-CS) carries significant mortality despite advances in revascularization and mechanical circulatory support. We sought to identify the process-based and structural characteristics of centers with lower mortality in AMI-CS. We analyzed 16,337 AMI-CS cases across 440 centers enrolled in the National Cardiovascular Data Registry's Chest Pain-MI Registry, a retrospective cohort database, between January 1, 2015, and December 31, 2018. Centers were stratified across tertiles of risk-adjusted in-hospital mortality rate (RAMR) for comparison. Risk-adjusted multivariable logistic regression was also performed to identify hospital-level characteristics associated with decreased mortality. The median participant age was 66 (interquartile range 57 to 75) years, and 33.0% (n = 5,390) were women. The median RAMR was 33.4% (interquartile range 26.0% to 40.0%) and ranged from 26.9% to 50.2% across tertiles. Even after risk adjustment, lower-RAMR centers saw patients with fewer co-morbidities. Lower-RAMR centers performed more revascularization (92.8% vs 90.6% vs 85.9%, p <0.001) and demonstrated better adherence to associated process measures. Left ventricular assist device capability (odds ratio [OR] 0.78 [0.67 to 0.92], p = 0.002), more frequent revascularization (OR 0.93 [0.88 to 0.98], p = 0.006), and higher AMI-CS volume (OR 0.95 [0.91 to 0.99], p = 0.009) were associated with lower in-hospital mortality. However, several such characteristics were not more frequently observed at low-RAMR centers, despite potentially reflecting greater institutional experience or resources. This may reflect the heterogeneity of AMI-CS even after risk adjustment. In conclusion, low-RAMR centers do not necessarily exhibit factors associated with decreased mortality in AMI-CS, which may reflect the challenges in performing outcomes research in this complex population.

A collaborative approach to develop indicators for quality of care for ST segment Elevation Myocardial Infarction in networks without coronary intervention: A position paper

BACKGROUND

Data about performance measures (PM) in patients with ST segment Elevation Myocardial Infarction (STEMI) in low- and middle-income countries is really scarce. One of the reasons is the lack of appropriate measures for these scenarios where coronary intervention is not the standard treatment.

OBJECTIVE

This study aimed to develop a set of PM and quality markers for patients with STEMI in these countries.

METHODS

Two investigators systematically reviewed existing guidelines and scientific literature to identify potential PM by referring to documents searched through PubMed from 2010 through 2019, using terms "Myocardial Infarction", "STEMI", "quality indicator", and "performance measure". A modified Delphi technique, involving multidisciplinary panel interview, was used. A 15-member multidisciplinary expert panel individually rated each potential indicator on a scale of 1 (lowest) to 5 (highest) during three rounds. All indicators that received a median score ≥4.5, in final round without significant disagreement were included as PM.

RESULTS

Through the consensus-building process, 84 potential indicators were found, of which 10 were proposed as performance measures and 2 as quality metrics, as follows: Pre-Hospital Electrocardiogram; Patients with reperfusion therapy; Pre-hospital Reperfusion; Ischemic time less than 120 minutes; System delay time less than 90 minutes; In-hospital Mortality; Complete in-hospital Treatment; Complete in-hospital Treatment in patients with Heart Failure; 30 day-Re-admissions; 30 day-mortality; Patients with in-hospital stress test performed; and, Patients included in rehabilitation programs.

CONCLUSION

This document provides the official set of PM of attention in ST segment Elevation Myocardial Infarction of the Cuban Society of Cardiology and Cuban National Group of Cardiology.

Quality of care for patients with ST-segment Elevation Myocardial Infarction before COVID-19 pandemic in Cuba: review of 17 reports with 7823 patients

BACKGROUND

In Cuba, there is neither a registry of ST Elevation Myocardial Infarction (STEMI), nor are analysis of performance measures widely reported.

OBJECTIVE

A review of Cuban studies of patients with STEMI was carried out to describe quality of medical care.

METHODS

Cochrane Library, EMBASE, PubMed, Scopus and SciELO, as well as archives of national journals, were all searched for articles on STEMI in Cuba, from 2000 to March 2020. They were included if they reported number or percentage of application of reperfusion therapy; administration of aspirin, enalapril-captopril (ACEI) or beta-blockers; status of patients at discharge; and patient or system delay times. Finally, 17 reports with 7823 patients were included.

RESULTS

Thrombolytic therapy was administered to 3991 patients (51%), and 695 patients (8.9%) died. Only four studies, with 880 patients, presented data about prescription of ACEI, aspirin, and beta-blockers, which were administered to 381 (45.3%), 824 (93.6%), 464 (52.7%) patients, respectively. Coronary intervention was reported in 5 studies with 3422 patients, being performed in 661 (19.3%).  Conclusions: Quality of care of patients with STEMI seems to be poorer than reported in similar scenarios. Thrombolytic administration is still low, although mortality decreases in this period. Other pharmacological treatments were insufficiently fulfilled.
