DVT Evaluation at the Bedside: How On-Site Imaging Changes the Workflow

A venous duplex study for deep vein thrombosis evaluation is not a complicated exam to perform. What is complicated is everything a facility has to arrange in order for it to happen. The exam itself takes a defined amount of time; getting the patient to an imaging department can take the better part of a day. When the ultrasound comes to the patient instead, the exam stays the same and the surrounding workflow changes almost completely.

This article describes the workflow difference in concrete terms for facilities weighing the two models: what steps disappear, what steps appear, who is involved, and what the facility needs ready. It does not address how a venous duplex study is interpreted, which is entirely the responsibility of the physician caring for the patient.

What the study involves

A venous duplex study for DVT evaluation examines the deep venous system of the legs or arms using B-mode imaging, compression and colour Doppler to assess whether blood is moving normally through the veins. The technologist works through the segments the protocol covers, documents each, and records the findings on a worksheet alongside the images. Full detail on the exam is on the venous duplex DVT evaluation exam page.

We perform complete protocols rather than abbreviated looks. That is a statement about scope, not about accuracy — the point is simply that the ordering physician receives the segments they expect to see documented, rather than a partial study performed under time pressure.

The send-out workflow, step by step

1. 1
   Order written
   The physician orders the study.
2. 2
   Imaging appointment sought
   Someone calls an outside department or vascular lab and finds a slot. Availability, not clinical priority, determines when the study happens.
3. 3
   Transport arranged
   Non-emergency transport is booked, which introduces a second schedule that has to align with the first.
4. 4
   Escort assigned
   For many patients — particularly in post-acute and long-term care — a staff member accompanies them, removing that person from the floor for hours.
5. 5
   Patient leaves the building
   Meals, therapy, medication timing and family visits are all worked around the trip.
6. 6
   Study performed
   The exam itself: a modest fraction of the elapsed time.
7. 7
   Patient returns
   Often late in the day, frequently tired, sometimes having missed therapy entirely.
8. 8
   Report follows
   The report comes back on the outside department's timeline, through whatever channel was arranged.

Eight steps, two schedules to reconcile, and one of them outside the facility's control. The failure mode is not dramatic — it is drift. Orders sit because arranging the trip is harder than writing the order.

The bedside workflow

1. 1
   Order written
   Unchanged.
2. 2
   Added to the imaging list
   The order goes onto the list for the facility's next scheduled imaging visit — for most buildings a standing recurring slot rather than a bespoke booking.
3. 3
   Technologist arrives and checks in
   The list is confirmed against the orders, and precautions and mobility limitations are reviewed at the nurses' station or front desk.
4. 4
   Study performed at the bedside or in the exam room
   The patient does not leave the building. Staff assist briefly with positioning if needed.
5. 5
   Equipment cleaned, next patient
   The technologist moves through the list.
6. 6
   Images and worksheet handed off
   They go to the physician who will interpret the study, by the route the facility specified in advance.

The steps that disappear are the ones the facility never wanted to own: transport coordination, escort assignment, and reconciling two external schedules. The step that appears is scheduling discipline — maintaining a list and a recurring slot.

What the facility needs ready

Where this changes the most

Skilled nursing and rehabilitation

This is where the difference is starkest, because the send-out cost is highest. New unilateral leg swelling in a recently immobilised or post-surgical resident is a common reason a physician wants imaging promptly, and it is exactly the situation in which transport is most burdensome. The full operational picture for these buildings is in how mobile vascular ultrasound works in a nursing home or SNF.

Primary care and specialty offices

For an office, the change is about the patient rather than staff time. A patient sent across town for a study may not go. A patient imaged during the visit they are already attending does. That retention effect is the same one described in bringing vascular imaging into a podiatry practice.

Homebound patients

For patients who cannot reasonably travel at all, on-site imaging is not a convenience but the difference between the study happening and not happening. That situation has its own logistics, covered in serving homebound patients with mobile imaging.

Scheduling patterns that hold up

Facilities that succeed with bedside imaging stop booking reactively. A standing slot — a set morning weekly or fortnightly — means charge nurses and front-desk staff know when imaging happens, orders stop accumulating unnoticed, and the per-patient overhead of setup and travel falls because the technologist works a list.

Multi-site operators sequence geographically. A single day covering Orland Park, Tinley Park, Oak Lawn and Palos Heights is realistic; adding Joliet or Aurora generally warrants its own day. The Northwest Indiana communities group similarly — Hammond, Munster and Schererville together, with Crown Point, Valparaiso and Michigan City on a wider loop. Telling us your site clusters up front produces a schedule that survives contact with reality.

Volume that justifies dedicated coverage

Some facilities have enough venous volume that recurring visits stop being the right shape, and a credentialed technologist covering the building on a defined term makes more sense. That decision and the term lengths available are covered in RVT staffing contracts and how 3, 6 and 9-month coverage models work. The broader set of mobile ultrasound and staffing services describes what else can run in the same visit — arterial studies, carotid duplex, aortic evaluation and echocardiography among them.

Who performs the studies

Bedside venous duplex studies are performed by credentialed, RVT-certified technologists, and our vascular technologists trained through the Rush University vascular ultrasound program. The facility types we work with are listed on our facilities we serve page.

Practical takeaway

Count the venous studies your facility sent out last quarter, the staff hours each trip consumed, and how many orders sat longer than anyone wanted. If those numbers are uncomfortable, the fix is not a faster outside department — it is removing the transport step from the workflow entirely.
