Running a Study with No Sites: What Changes, What Doesn’t

Imagine a study without a single physical site. No reception desk. No cabinets full of forms. No onsite PI. In fully virtual trials, everything happens online or by phone. This model is gaining traction, particularly in low-risk consumer health and lifestyle research. But while the infrastructure changes, not everything about running a trial does.

Let’s break it down into what genuinely changes and what simply shifts form.

‍

What Changes

Participant contact becomes entirely digital or remote. Video calls replace face-to-face visits. Study kits are shipped to homes. Data flows in through apps and wearables. This can reduce geographic barriers, but it also puts more pressure on interfaces, logistics and participant communication.

Site roles are often absorbed by a central study team. Screening, consent and follow-up tasks need careful coordination to avoid overloading one part of the workflow. The structure becomes flatter, but also potentially more fragile if not carefully managed.

Monitoring and oversight become asynchronous. Instead of flying out to review binders, monitors track eCRFs and system logs from a distance. That changes how quality signals are interpreted and raises the importance of audit trails and real-time visibility.

What Doesn’t Change

People still need support. Just because the trial is remote doesn’t mean it runs itself. Participants still have questions, miss tasks or get confused. Human contact is still essential—just routed differently.

Protocols still matter. A digital trial doesn’t eliminate the need for well-defined procedures. In fact, loose protocols are even harder to manage remotely. Every step needs to be executable without in-person clarification.

Regulatory expectations stay put. Ethics reviews, data handling requirements, safety reporting—all the usual obligations still apply. If anything, documentation and transparency become more important when the process is less visible.

The same questions drive the work. Who is eligible? What data do we need? How do we protect privacy? A virtual trial still answers these questions—it just answers them with different tools.

A Word of Caution

Fully virtual trials can appear simpler, but they often involve more planning upfront. Without physical sites to absorb the friction, every weak point is exposed. If a task flow is unclear or an instruction is vague, there’s no coordinator nearby to step in. So more attention needs to go into interface design, logistics planning and real-time support.

The shift is real. But the fundamentals of good trial conduct remain the same. Fully virtual studies do not simplify the work. They just relocate it.
