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

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: Completed
• Conditions: Peripheral Artery Disease
• Intervention / Treatment: Other: Intervention A - Vascular Care + site 6MWT administration; Other: Intervention B - Standard Care + site 6MWT administration; Other: Intervention A - Vascular Care + CPC EQuIP 6MWT administration; Other: Intervention B - Standard Care + CPC EQuIP 6MWT administration

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Intervention A + site 6MWT administration; Intervention A subjects will receive a vascular care team approach to care including pharmacy and healthcare provider assistance with medication adherence. 6-Minute Walk Test (6MWT) will be administered by site staff.	Other: Intervention A - Vascular Care + site 6MWT administration; Implementation of multiple strategies related to improving lipid management, starting with a referral to the vascular care team. The subject will undergo a visit with a vascular care team, including a Vascular Medicine specialist who will obtain a patient history and prescribe a lipid lowering therapy regimen. The subject will also meet with a pharmacist to answer questions related to access to medications, drug side effects, and potential interactions with the subject's other medications. Additionally, the site staff will conduct and guide the subjects through 6MWTs at protocol-dictated time points.
Active Comparator: Intervention B + site 6MWT administration; Intervention B will receive 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. 6-Minute Walk Test (6MWT) will be administered by site staff.	Other: Intervention B - Standard Care + site 6MWT administration; Consists of provision of the treating provider with a copy of the 2018 ACC/AHA Guidelines on the Management of Blood Cholesterol. Subjects will return at 6 and 12 months for lab draws and endpoint event assessments but will not meet with vascular care team. Additionally, the site staff will conduct and guide the subjects through 6MWTs at protocol-dictated time points.
Active Comparator: Intervention A + CPC EQuIP 6MWT administration; Intervention A subjects will receive a vascular care team approach to care including pharmacy and healthcare provider assistance with medication adherence. 6-Minute Walk Test (6MWT) will be administered by CPC EQuIP staff.
