About this study
Official title: Feedback and Education Intervention to Reduce Inappropriate Transthoracic Echocardiograms (TTE)
This study is an international, prospective, multi-centred, investigator blinded, randomized control trial of an educational and feedback-based intervention vs. usual care to study the proportion of inappropriate TTEs ordered by clinicians in ambulatory care.
The American College of Cardiology collaborated with the American Society of Echocardiography to develop its Appropriate Use Criteria (AUC) for Echocardiography in 2007, and were updated in 2011.

We created an innovative education and feedback-based intervention that we hypothesize will reduce the proportion of inappropriate TTEs ordered in clinical practice. Our objective is to prospectively study the following intervention in a multicentre, randomized control trial format to determine if this intervention will reduce inappropriate TTEs and the number of TTEs ordered in practice.
The study will take place at multiple hospitals in Canada the United States. Participants include cardiologists and primary care providers (both general internal medicine and family practice) who provide ambulatory care.
Once cardiologists and primary care physicians are recruited for the study, they will be randomized into one of two arms: 1) Intervention group, 2) Control group.
A physician's TTE ordering information will be ascertained by review of the individual TTE order and by review of the patient's medical record. Trained research coordinators at each site will review the TTE order for indication and review the patient record to ascertain clinical circumstances regarding the TTE order. The individual research coordinator will review this information using the 2011 AUC and classify the TTE as Appropriate (A), Inappropriate (I) or Uncertain (U), and assign the TTE order the most appropriate indication number accordingly. Research Coordinators will be blinded to which physicians are in the intervention or control group.
Research Coordinators at each site will be responsible for individual physicians' TTE order classifications but will be blinded to study group. Once monthly TTE orders are classified and collated, this information will be transmitted to the central research laboratory, where a research coordinator will collate all of the results and transmit monthly feedback reports to individual physicians. The control group will order TTEs as is their usual practice.
Read the detailed description
This study is an international, prospective, multi-centred, investigator blinded, randomized control trial of an educational and feedback-based intervention vs. usual care to study the proportion of inappropriate TTEs ordered by clinicians in ambulatory care.
Increased inappropriate TTE utilization represents a burden to health budgets as costs rise with increased utilization, and to patients themselves who are burdened with unnecessary procedures that can adversely affect quality of care. Rising utilization in an environment with limited supply also creates barriers to access and increased wait times for those patients in the community who are awaiting necessary TTEs.
In a move to balance the concern regarding rising utilization while still ensuring physician autonomy on access to ordering cardiac tests and procedures, the American College of Cardiology collaborated with the American Society of Echocardiography to develop its Appropriate Use Criteria (AUC) for Echocardiography in 2007, and were updated in 2011. AUC were created by using the modified RAND appropriateness method. Studies applying AUC to TTE orders at single centres in the US found inappropriate TTE rates in ambulatory (outpatient) care ranging up to 35%.
We have successfully created an innovative education and feedback-based intervention that we hypothesize will reduce the proportion of inappropriate TTEs ordered in clinical practice, which will save healthcare dollars and improve quality of care and access to echocardiography. Our objective is to prospectively study the following intervention in a multicentre, randomized control trial format to determine if this intervention will reduce inappropriate TTEs and the number of TTEs ordered in practice.
The study will take place at multiple hospitals in Canada the United States. Participants include cardiologists and primary care providers (both general internal medicine and family practice) who provide ambulatory care. Only providers who see patients in ambulatory care clinics will be included. Pediatric cardiologists and physicians who specialize primarily in adult congenital heart disease will be excluded from the study. Physicians who are approached will be required to provide written consent prior to participation in the study.
Once cardiologists and primary care physicians are recruited for the study, they will be randomized into one of two arms: 1) Intervention group, 2) Control group. Randomization will occur at the same time for each site to ensure the study start date is consistent across all sites.
Collection of TTE ordering information and TTE order classification:
A physician's TTE ordering information will be ascertained by review of the individual TTE order and by review of the patient's medical record. This may be through review of the Electronic Medical Record (EMR) or paper chart, depending on the individual site. Trained research coordinators at each site will review the TTE order for indication and review the patient record to ascertain clinical circumstances regarding the TTE order. The individual research coordinator will review this information using the 2011 AUC and classify the TTE as Appropriate (A), Inappropriate (I) or Uncertain (U), and assign the TTE order the most appropriate indication number accordingly. TTE orders that do not have a corresponding indication number will be designated as unclassifiable. Research Coordinators will be blinded to which physicians are in the intervention or control group. This system of TTE classification has been previously piloted and published by our group in two recently published studies, and the rate of successful classification was greater than 98%.
Dissemination of TTE monthly feedback reports:
Research Coordinators at each site will be responsible for individual physicians' TTE order classifications but will be blinded to study group. Once monthly TTE orders are classified and collated, this information will be transmitted to the central research laboratory, where a research coordinator will collate all of the results and transmit monthly feedback reports to individual physicians. This process ensures that local site coordinators and the study investigators are blinded to the results to the study, while still enabling the creation and dissemination of physician related feedback reports to the intervention group. The control group will order TTEs as is their usual practice.

Questions about this trial
What is this clinical trial studying?
A study testing Education and Feedback in people with CARDIOVASCULAR DISEASES, run by Women's College Hospital at 6 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 9 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 6 sites in Canada, United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Proportion of Inappropriate Transthoracic Echocardiograms ordered (%) (time frame: 18 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02038101, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
