Association Between Physicians' Appropriate Use of Echocardiography and Subsequent Healthcare Use and Outcomes in Patients With Heart Failure.

Background There is little understanding of whether a physician's tendency to order an inappropriate cardiac service is associated with the use of other cardiac services and clinical outcomes in their patients with heart failure (HF). Methods and Results We conducted a secondary analysis of 35 Ontario-based cardiologists who participated in the control arm of the Echo WISELY (Will Inappropriate Scenarios for Echocardiography Lessen Significantly) trial. Transthoracic echocardiograms, ordered during the trial, were classified as rarely appropriate (rA), appropriate, or maybe appropriate on the basis of the 2011 appropriate use criteria.

Low-Value Transthoracic Echocardiography, Healthcare Utilization, and Clinical Outcomes in Patients With Coronary Artery Disease.

Background: The relationship between ordering frequency of rarely appropriate transthoracic echocardiograms on healthcare utilization and patient outcomes in coronary artery disease (CAD) is not known. Our objective was to investigate practice patterns of cardiologists who order a high frequency of low-value transthoracic echocardiograms in patients with CAD and whether practice behavior influences patient outcomes.

Methods And Results: A retrospective cohort of outpatient CAD patients was accrued by identifying patients with at least 1 visit to 1 of 35 Ontario-based cardiologists in the EchoWISELY randomized clinical trial (Will Inappropriate Scenarios for Echocardiography Lessen Significantly) control group.

Design and methods of the Echo WISELY (Will Inappropriate Scenarios for Echocardiography Lessen SignificantlY) study: An investigator-blinded randomized controlled trial of education and feedback intervention to reduce inappropriate echocardiograms.

Background: Appropriate use criteria (AUC) for transthoracic echocardiography (TTE) were developed to address concerns regarding inappropriate use of TTE. A previous pilot study suggests that an educational and feedback intervention can reduce inappropriate TTEs ordered by physicians in training. It is unknown if this type of intervention will be effective when targeted at attending level physicians in a variety of clinical settings.
