Implementation of Vascular Care Team to Improve Medical Management of PAD Patients

February 6, 2024 updated by: Colorado Prevention Center

Implementation of Vascular Care Team to Improve Medical Management of Peripheral Arterial Disease (PAD) Patients

This study intends to evaluate the efficacy of a multidisciplinary vascular care team utilizing an intensive guideline-based lipid reduction program in improving risk factor modification as measured by LDL-C reduction at 12 months in patients with peripheral artery disease (PAD). An additional objective is to understand the potential reach and impact if this program were extended across the University of Colorado Healthcare (UC Health) System.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients with PAD and elevated LDL-C who are cared for at the University of Colorado (UC) and who provide consent will be randomized 1:1 to Intervention A, a vascular care team approach including pharmacy and healthcare provider assistance with medication adherence, versus Intervention B consisting of standard care augmented with a single consultation with a Vascular Medicine physician who will provide the treating doctor with a personalized risk assessment for the patient and a summary of the 2018 American College of Cardiology (ACC)/American Heart Association (AHA) Guideline on Management of Blood. In order to investigate the efficacy of the CPC Endpoint Quality Intervention Program (EQuIP), subjects will additionally be randomized 1:1 to an investigative site conducted Six-Minute Walk Test or an EQuIP team led Six-Minute Walk Test. Quality of Life data will be collected from all subjects. There will also be an observational cohort (registry) to understand current practice patterns and outcomes in a non-interventional PAD population within the UC Health system in order to assess the potential impact of Intervention A after conclusion of the randomized study.
