Hybrid Trial Support Model
Direct patient support · Site relief
The pitch for decentralized clinical trials included significant reduction in site workload. And in narrow operational terms — fewer patients physically in clinic, fewer blood draws, fewer scheduling conflicts — that is sometimes true. But the broader workload picture is more complicated.
Hybrid trials add coordination overhead that is easy to underestimate at the protocol design stage: technology onboarding calls with patients, troubleshooting wearable devices and eDiary apps, answering questions about at-home procedures, managing home nursing scheduling, and responding to patients who are confused about what they're supposed to be doing this week. None of these tasks disappear in a hybrid model — they just move to a different part of the workflow.
When they default to site coordinators — which they often do, because coordinators are the ones with patient relationships — the net effect on site burden is redistributed effort, not reduced effort. And coordinators who are managing a full clinic schedule on top of DCT coordination overhead make more errors, respond more slowly to patient issues, and experience higher turnover.

Identifying where burden actually comes from is the prerequisite for addressing it. These are the categories that most commonly appear in hybrid trial retrospectives.
Wearable devices, eDiary apps, home spirometry equipment, and other patient-facing technologies generate a continuous stream of support requests. Without a dedicated support function, these land on site coordinators who are not equipped to resolve technical issues quickly.
In a pure site-based model, compliance issues surface at visits. In hybrid models, monitoring between visits is continuous — and when a patient falls behind on eDiaries or misses a home assessment, someone needs to notice and act. If that person is the site coordinator, it adds to their burden.
Hybrid trials often enroll geographically diverse populations. Sites with diverse catchment areas face a disproportionate communication burden when they are responsible for patient outreach in multiple languages.
Home nursing visits, at-home lab sample collections, and remote assessments require scheduling, confirmation, and follow-up. When site coordinators own this workflow, it becomes one of the largest time sinks in hybrid operations.
Protocol amendments, wearable additions, and sub-study enrollment all require re-consent. In hybrid trials, coordinating this remotely — while ensuring it is documented correctly — adds significant administrative load.
App updates, device firmware changes, and platform changes require patient re-onboarding. When this falls on site staff, it generates reactive workload spikes that are difficult to plan for.
The structural fix is a patient support layer that operates independently of site bandwidth — handling patient communication, compliance monitoring, and technology support directly so site staff can focus on clinical tasks.

No. Technology can surface compliance issues more efficiently, but it does not resolve them. The reduction in site burden comes from taking tasks off site staff — which requires a human support layer, not a better dashboard.
Map the expected weekly task load per coordinator, including all new tasks added by DCT components. Studies that add five to eight new coordination touchpoints per patient without corresponding support will quickly overwhelm coordinator capacity.
Yes, and the value is highest at smaller or community sites with limited coordinator bandwidth. Academic medical centers with dedicated research staff can absorb more DCT overhead — community sites typically cannot, and they are where most patients are enrolled.
Delve provides direct-to-patient support that operates independently of site bandwidth — reducing coordinator workload while improving patient compliance and retention.
