What DCT Local Collection Infrastructure Actually Requires

The Gap That Shows Up in the Data

Here's a problem that comes up in DCT protocol design more often than it should: you can qualify a local collection site on paper — license, liability, basic credentials, proof of general phlebotomy competency — and still send the first participant draw to a collector who has never seen your collection kit.

Doesn't know your tube type or draw order. Hasn't completed a chain of custody document to your sponsor's standard. Doesn't know what to do if the kit instructions don't match standard practice.

That's not a training failure at the local site level. That's a design gap at the protocol level.

In a traditional site-based trial, this problem doesn't arise the same way. The investigational site's staff handle collections. They're trained under the site's SOPs, they operate within an established quality infrastructure, and their procedures are directly supervised.

In a decentralized model, the local collector isn't part of that system. The collection moved to the community — to a pharmacy, a draw site, a mobile phlebotomist — but the oversight didn't automatically move with it.

Explicit collection infrastructure is how you close that gap. And it's more specific than most protocol designs account for.

What Explicit DCT Collection Infrastructure Requires

It means four things being in place before the first participant draw. Not after.

1. Protocol-Specific Training — Not Just a Phlebotomy Certificate

A general phlebotomy credential confirms someone can draw blood. It says nothing about whether they're qualified to draw blood for your specific study.

Protocol-specific training for a DCT study covers the collection kit components, the tube type and draw order specified in the protocol, the temperature and handling requirements that preserve specimen integrity, the chain of custody documentation the sponsor requires, and the deviation reporting procedure for when something goes wrong.

Sticklogistics® — a learning management system powered by MOMS — delivers this digitally. When a study connects to the MOMS platform, the collection protocol goes into Sticklogistics®. Connected MAPs complete protocol-specific training to the sponsor's standard before they're cleared to collect for that study. Training completion is documented and verifiable.

The result is a collector whose readiness for your specific protocol is confirmed. Not assumed.

2. Chain of Custody That Works in the Field, Not Just on Paper

Chain of custody in a DCT isn't just a documentation requirement. It's the evidentiary record connecting the specimen the central lab receives to the participant draw it originated from — with continuous documentation of handling, temperature, and transfer at every step.

The chain of custody that works in a site-based trial, where clinical staff manage the custody record and ship specimens under established SOPs, doesn't automatically work when a local collector at a draw site is managing a custody record they may have never seen before. 

Building custody discipline into local collection infrastructure means training collectors on the documentation requirements before the first draw — not explaining it during a courier handoff. Custody records completed correctly at every step, rather than reconstructed after an issue surfaces.

3. Deviation Management Before It Becomes a Sponsor Problem

Deviations happen in every study. The question is whether they get identified, documented, and communicated before they become a quality event.

In a site-based trial, deviation management at the collection level is built into the site's quality system. In a decentralized model, that has to be built explicitly. The local collector needs to know what constitutes a deviation for this study, how to document it, and who to communicate it to before the specimen ships.

MOMS builds deviation reporting into the Sticklogistics® training curriculum for every DCT study connection. The MAP who collects for a study knows the procedure before the first draw — not after the first issue.

4. Credentialing That Scales When the Study Does

Local collector credentialing for a DCT isn't a one-time event. Studies scale. Enrollment expands into new geographies. Dropout requires replacement recruitment in markets that weren't initially active.

The credentialing infrastructure has to scale with the study — which means a systematic process for qualifying collectors in new geographies, not a one-off review every time the enrollment map changes.

MOMS maintains ongoing credentialing monitoring across the MAP network: license status, liability coverage, and credential expiration tracked continuously. When a study expands into a new geography, the MAPs in that geography who have been continuously monitored are available immediately — not after a weeks-long credentialing review.

Why This Has to Be Built Before Site Initation

A training gap discovered after the first collection event is discovered in the data.

A first draw that produces a deviation, a chain of custody error, or a specimen integrity issue because the local collector wasn't trained to the study's standard generates a quality event — one that has to be reported, investigated, and remediated. That remediation is almost always more expensive and more time-consuming than the training would have been.

The infrastructure that works is the infrastructure that was built correctly before the first participant showed up.

What MOMS Provides for DCT Studies

When a clinical study connects to the MOMS platform, the collection infrastructure is built from the protocol requirements:

• Protocol loaded into Sticklogistics® — lab/sponsor provided curriculum built to sponsor standard

• Connected MAPs complete protocol-specific training before first draw clearance

• Chain of custody documentation integrated into collector training
  
  

• Deviation reporting procedure trained before first collection event

• Credentialing monitored continuously across the active MAP network
  
  
• Coverage available in all 50 states — including rural counties and smaller MSAs where site-based collection isn't available

For CROs and sponsors evaluating local collection infrastructure for Phase II and Phase III decentralized or hybrid studies: this conversation is worth having before the protocol is finalized. Not after site initiation.
