Improving Cardiovascular Risk Prediction Using Hand Held Carotid Ultrasonography Study — MERC-CIMT  

Stroke Clinical Trial

Official title: Improving Cardiovascular Risk Prediction Using Hand-Held Carotid Ultrasonography Study

Status Completed

Clinical Trial Summary

1) Research questions:

1a. Can non-sonographer health care professionals in a community medical office practice setting be trained to detect and evaluate subclinical atherosclerosis?

1b. Can carotid ultrasound performed in community office practices improve physician use of evidence-based, risk-reducing interventions and patient motivation to adhere to therapeutic recommendations?

Clinical Trial Description

Health care providers from five medical practices will complete a 2-day training program that teaches instrumentation, scanning, measurement, quality assurance, and interpretation. They also will learn about CV risk assessment, intervention, and how to use an ultrasound-based CV risk stratification and treatment algorithm. After certification, each site will recruit 70 patients from their practice (total N=350). Subjects will complete their routine office visit and a pre-test survey designed to assess motivation and intention to change. The physician's initial plan of action based on usual care will be recorded. Next, the subject will have a standardized CV risk carotid ultrasound. The physician will revise his/her treatment plan based on the scan results and an ultrasound-based risk assessment algorithm that includes CV risk factors and ultrasound data. Evidence-based treatment recommendations for lifestyle changes and risk factor targets will be provided. The physician's scan-based plan of action will be recorded. The subject will be informed of the results and repeat the survey. All images, interpretations, and recommendations will be reviewed by the UW AIRP. ;
