Chest pain is one of the most common reasons for emergency room visits. But once patients arrive, clinicians have wide discretion in determining which tests are needed to evaluate the patients’ heart health. A recent study in JAMA Internal Medicine from Yale School of Medicine evaluates the variation in clinical decisions, the costs, and patient outcomes in patients with suspected heart attacks. 

“The healthcare system must find new methods to reign in costs, but it is essential that this be done in ways that does not hurt patients,” said first author and Yale School of Medicine student Kyan Safavi. “This study demonstrates one area in which utilization of expensive healthcare resources could potentially be reduced without diminishing the quality of care that the patient receives.”

Non-invasive cardiac imaging, such as CT scans and MRIs, is an easy and safe way to gain a better understanding of heart health and the risk of heart attack. This study, which surveyed over half a million patients in 224 hospitals across the United States, showed that the use of non-invasive cardiac imaging in patients varied widely between hospitals. Hospitals that used imaging tests more frequently were also more likely to admit patients for hospitalization and to subsequently perform more invasive testing, such as coronary angiogram.

Despite wide variation in the use of imaging, the use of cardiac interventions, such as coronary artery stents and bypass surgery, was much more consistent across hospitals. There was also no difference in readmission outcomes across hospitals. This study adds to growing evidence that greater utilization of healthcare resources is not necessarily associated with better patient outcomes.

Other Yale authors on the study include Shu-Xia Li, Kumar Dharmarajan, Arjun K. Venkatesh, Kelly M. Strait, Haiqun Lin, and Harlan M. Krumholz. Timothy J. Lowe from Premier Inc., NC; Reza Fazel from Emory University; and Brahmajee K. Nallamothu from University of Michigan also contributed to the study.

This study was supported in part by grants from the Patrick and Catherine Weldon Donaghue Medical Research Foundation (DF10-301); National Center for Advancing Translational Sciences (UL1 RR024139-06S1); (Center for Cardiovascular Research at Yale University) from the National Heart Lung and Blood Institute Center for Cardiovascular Research at Yale (U01 HL105270-04); National Institutes of Health (HL007854); the John A. Hartford Foundation; and the American Federation for Aging Research.
