What Is Clinical Trial Intake?
Clinical trial intake is the operational bridge between a referral or patient inquiry reaching a research site and the next site-approved step.
It can organize candidate-reported information, follow-up, open items, and handoff readiness. Formal eligibility, clinical screening, and informed consent remain with the research site.
Direct answer
Clinical trial intake turns incoming interest into an organized, owned record
A referral alone tells a site that someone has raised a hand. Intake answers the operational questions that follow: Who owns the record? What information is required? What has the candidate reported? What is still missing? What follow-up has occurred? What is the next approved step?
The exact workflow varies by site and protocol. At some sites, intake ends before preliminary prescreening begins; at others, site-approved preliminary questions sit inside the same pre-consent workflow. The durable design principle is clear ownership with a clear authority boundary: intake prepares an organized record, while the research site applies clinical judgment and determines the appropriate clinical next step.
The authority boundary
A practical distinction for sites designing the workflow.
Intake can organize
- Referral and inquiry records
- Candidate-reported information
- Site-approved preliminary questions
- Follow-up and open items
- Handoff preparation
The site retains
- Clinical judgment and medical interpretation
- Formal eligibility decisions
- Clinical screening procedures
- Informed consent and clinical relationships
- Protocol oversight and randomization
Operational mechanism
What does a structured intake process actually do?
The details should be site-defined, but a usable intake system usually needs six operational functions. None of them requires intake staff to make a clinical eligibility decision.
Create an owned intake record
Document the inquiry or referral, source, date, study context, responsible owner, and the next expected action in a consistent record.
Confirm usable contact information
Verify the contact details and communication information the site requires so later outreach does not begin by reconstructing the record.
Collect site-defined intake information
Capture required administrative details and candidate-reported information using the site-approved workflow, while keeping unresolved items visible.
Manage permitted follow-up
Document outreach, responses, current status, and the next action so a candidate does not depend on one person remembering what happened last.
Prepare the handoff
Organize candidate-reported responses, available documentation, follow-up history, and open items into a record the receiving site team can review efficiently.
Route or escalate appropriately
Move the record to the site-defined next step, or escalate questions that require clinical judgment rather than interpreting them within intake.
Workflow view
Where intake sits before site clinical review
Intake is not a substitute for screening. Its job is to make the pre-consent record easier to understand and act on before the research site applies the clinical and protocol-specific judgment that only the site can provide.
- 1
Stage 1
Referral or inquiry
Interest enters the research site’s process.
- 2
Stage 2
Structured intake
Ownership, required information, status, and next action are documented.
- 3
Stage 3
Preliminary information
Candidate-reported information and site-approved preliminary questions may be collected where authorized.
- 4
Stage 4
Handoff readiness
Open items and prior follow-up are visible to the receiving team.
- 5
Stage 5
Authorized site review
The research site applies clinical judgment and determines the appropriate next step.
Why the sequence matters
FDA guidance on screening tests prior to study enrollment distinguishes preliminary contact and basic eligibility conversations from clinical screening procedures performed solely to determine research eligibility; those research-only clinical procedures generally require informed consent first. A site’s intake workflow should therefore make escalation and authority explicit rather than asking intake staff to cross that line.
C2R operational framework
The C2R Intake Handoff Test
The C2R Intake Handoff Test is a five-question operational check for determining whether an intake record is ready to move forward for site review. The receiving team should be able to answer each question without reconstructing the story from scratch.
This is a Consent2Randomize operational framework, not an industry benchmark or regulatory standard. Sites should adapt it to their protocols, SOPs, IRB-approved materials, privacy requirements, and division of responsibilities.
- 1
Who is this record about?
Usable contact information and the relevant study or referral context are clear.
- 2
What has already been collected?
Required intake fields and candidate-reported information are visible without searching across disconnected notes.
- 3
What remains unresolved?
Missing, uncertain, or unanswered items are explicit rather than silently treated as complete.
- 4
What follow-up has occurred?
Prior outreach, responses, and current status are documented.
- 5
What happens next, and who owns it?
The receiving team can see the next action and the person or function responsible for it.

Operational value
How intake quality can affect downstream enrollment work
Intake is one operational factor in a much larger enrollment system. Protocol complexity, eligibility criteria, participant burden, referral quality, competition, geography, staffing, and many other conditions can affect enrollment performance. CTTI recruitment-planning guidance likewise addresses multiple design, feasibility, resource, communication, and implementation considerations.
What structured intake can do is make a narrower set of problems more observable: incomplete records, unclear ownership, undocumented follow-up, unresolved information, and handoffs that require reconstruction. Reducing those problems may improve the condition of the record reaching the next stage and help protect site capacity, but the effect should be measured locally rather than assumed.
What better intake should make easier to see
- Whether every new inquiry has a documented owner and next action.
- Which records are complete, incomplete, unreachable, or waiting on a site decision.
- Which open items are creating re-contact or reconstruction work.
- Whether the handoff gives the receiving team enough context to act without guessing.
Measurement guidance
How should a site measure clinical trial intake?
There is no single universal intake benchmark that fits every protocol or site. Start by defining each status and timestamp consistently, establish a local baseline, and then compare changes over time, by study, or by referral source where appropriate.
These measures describe workflow performance. They should not be treated as proof that intake alone caused a downstream enrollment result.
Time to first documented action
Start: referral or inquiry received. End: first documented operational action in the site-defined intake workflow.
Intake completion rate
Numerator: records reaching the site’s defined complete-intake state. Denominator: intake records opened in the same defined cohort or period; document exclusions such as duplicates.
Age of open items
Start: a required item is marked unresolved. End: the item is resolved or the record closes; for still-open items, report current age.
Follow-up attempts to disposition
Count documented, permitted outreach attempts from the first attempt until the record reaches a defined pre-consent status; define which attempts are included.
Time to handoff readiness
Start: referral or inquiry received. End: the record meets the site’s documented handoff-readiness criteria for authorized review.
Post-handoff rework rate
Numerator: handed-off records requiring intake clarification or reconstruction after handoff. Denominator: all handed-off records in the same period; define rework before tracking.
Where Consent2Randomize fits
Support after interest reaches the site and before consent
Consent2Randomize can support intake, candidate-reported information collection, site-approved preliminary prescreening, follow-up, appointment preparation or coordination where appropriate, documentation, open-item resolution, and structured handoff preparation.
The research site retains clinical judgment, formal eligibility decisions, clinical screening, protocol oversight, informed consent, medical interpretation requiring clinical judgment, clinical relationships, and randomization.
A useful service-fit question
When a coordinator opens a new candidate record, are they beginning site review, or are they first rebuilding the intake?
