Study of the Effectiveness of Report Cards on the Quality of Care for Heart Attack and Heart Failure Patients

2014-08-27 03:50:13 | BioPortfolio


Randomized cluster trial of cardiac report cards for AMI and CHF. 103 acute care Ontario hospitals/85 hospital corporations participating, randomized to two groups: Group A Early Feedback and Group B Delayed Feedback.

Two phases of retrospective chart review of AMI and CHF separations to assess the impact of the public release of hospital specific performance on a set of Canadian quality indicators.


Study Overview:

The EFFECT Study is one of the largest and most comprehensive initiatives in the world to measure and improve the quality of cardiac care. A randomized trial of cardiac care report cards, the study's objective is to determine whether developing and publishing report cards based on clinical data collected from patient charts leads to greater use of evidence-based therapy at hospitals that receive them.

The three-phase study focuses on acute myocardial infarction (AMI) and congestive heart failure (CHF) and involves 85 hospital corporations (consisting of 103 acute care hospitals) in Ontario. As part of the study design, the hospitals were randomized into two groups: Group A-Early feedback hospitals (44 hospital corporations/53 hospitals) and Group B-Delayed feedback hospitals (41 hospital corporations/50 hospitals).

Phase I A retrospective chart review of hospitalizations from 1999/00 and 2000/01 was conducted in the participating Ontario hospital corporations. Findings from Phase I were documented in two reports:

- Report 1. Report Cards on Group A-Early Feedback Hospitals, released January 2004;

- Report 2. Report Cards on Group B-Delayed Feedback Hospitals, to be released September 2005.

In addition to demographic and treatment information, study data also focus on two sets of quality indicators—one for AMI care and one for CHF care. Canadian Cardiovascular Outcomes Research Team (CCORT) investigators, in conjunction with the Canadian Cardiovascular Society (CCS), formed two expert panels to define Canadian AMI and CHF Quality Indicators. The expert panels' membership included clinical leaders in cardiology, internal medicine, family practice, nursing, pharmacy and epidemiology. The indicators are posted on the CCORT web site ( and have been published in the Canadian Journal of Cardiology. The study's Technical Advisory Committee reviewed all of the proposed AMI and CHF quality indicators and recommended a final list of indicators for inclusion in the EFFECT report cards.

Phase II Report Cards for Group A-Early Feedback Hospitals and Group B-Delayed Feedback Hospitals based on a second phase of retrospective chart review of 2004/05 hospitalizations. (Release in 2006/07)

Phase III Final Report—Impact Assessment: A comparison of results/improvement from Phase I to Phase II. (Release in 2006/07)

Sources of Funding The EFFECT study is being funded by the Canadian Institutes of Health Research (CHIR) Interdisciplinary Health Research Team (IHRT) Program and the Heart and Stroke Foundation of Canada, with in kind support from the Institute for Clinical Evaluative Sciences.

Principal Investigators The EFFECT study is being led by Dr. Jack V. Tu, MD, PhD, Senior Scientist, ICES, Canada Research Chair, Health Services Research.

Medical and Biotech [MESH] Definitions

The hospital unit in which patients with acute cardiac disorders receive intensive care.

A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (CORONARY ARTERY DISEASE), to obstruction by a thrombus (CORONARY THROMBOSIS), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (MYOCARDIAL INFARCTION).

Hand-sized cards with built-in computer chips used for accessing, storing, and protecting patients' medical information.

A malformation that is characterized by a muscle bridge over a segment of the CORONARY ARTERIES. Systolic contractions of the muscle bridge can lead to narrowing of coronary artery; coronary compression; MYOCARDIAL ISCHEMIA; MYOCARDIAL INFARCTION; and SUDDEN CARDIAC DEATH.

The hospital department responsible for the administration and provision of diagnostic and therapeutic services for the cardiac patient.
