Evaluation of an Electronic Health Record-based Screening Tool for Peripheral Artery Disease
Not Recruiting
Trial ID: NCT04054232
Purpose
This protocol represents a pilot randomized-controlled trial evaluating the effect of an
electronic health record (EHR)-based peripheral artery disease (PAD) screening tool on rates
of new non-invasive testing, diagnosis and treatment of PAD over a 6-month period. An
EHR-based PAD screening tool will be applied to the Stanford EHR, which will generate a group
of patients of varying risks of having undiagnosed PAD. Patients with the highest risk of
having undiagnosed PAD will then be evaluated for inclusion in this study. 1:1 randomization
will be performed on a consecutive basis until study enrollment is completed (25 patients per
arm).
Physicians of patients randomized to the intervention arm will be sent notification via an
EHR message detailing the patient's risk of undiagnosed PAD and suggestions for referral to
vascular medicine for risk assessment and/or non-invasive ankle brachial index (ABI) testing.
The primary outcome is number of patients receiving ABI testing for PAD at 6 months, with
secondary outcomes including number of new PAD diagnoses, number of new referrals to
cardiovascular specialists (vascular medicine, vascular surgery, and/or cardiology) and
number of patients receiving initiation of new cardiovascular medications (anti-platelet
agents, statins, and/or antihypertensive agents).
