Incomplete preliminary information
The intake record reaches preliminary review without the candidate-reported responses or context requested in the site-approved workflow.
Clinical Trial Prescreening Support
Clinical Trial Prescreening Support for Research Sites
Preliminary prescreening collects and documents candidate-reported information through site-approved questions, escalates clinical or protocol issues, and prepares the record for authorized site review before formal screening.
Why Prescreening Breaks Down
Why Prescreening Breaks Down
This page explains the preliminary prescreening workflow. It breaks down when candidate-reported information, documentation, status, escalation, or handoff expectations are unclear. The research site retains clinical interpretation and every formal eligibility decision.
Clinical or protocol questions lack escalation
Unclear responses remain in the operational queue instead of being documented and routed to authorized site personnel for interpretation.
Candidate status is not documented
Contact attempts, open questions, current interest, and the next action are difficult to see when teams use inconsistent status definitions.
Unclear handoffs into site review
Candidate-reported information reaches the site without a structured summary of completed steps, unresolved items, and contact history.
Poor visibility across the preliminary workflow
Without defined stages and dispositions, teams cannot distinguish records awaiting contact, information, escalation, or authorized site review.
Structured Prescreening Between Referral and Screening
Preliminary prescreening sits between referral intake and formal site screening. It organizes site-approved questions, candidate-reported responses, contact history, status, unresolved items, and escalation before authorized site review.
A research site can operate the workflow internally or use Consent2Randomize's hands-on intake and preliminary prescreening service as an implementation option. The service executes agreed operational steps within the site's approved workflow.
The research site determines eligibility and retains formal screening, medical decisions, informed consent, protocol oversight, investigator responsibility, and randomization decisions.
Putting the Preliminary Workflow Into Practice
The workflow below shows how preliminary information moves from a complete intake record to authorized site review. Clear ownership and escalation also support coordinator-capacity planning without transferring clinical authority.
Record Completeness Review
Confirm that the referral contains the information required to begin the site-approved preliminary workflow.
Site-Approved Preliminary Questions
Collect candidate-reported responses without interpreting them as a formal eligibility assessment.
Documentation and Status
Record contact attempts, responses, unresolved items, current status, and the next operational action.
Clinical and Protocol Escalation
Route unclear clinical or protocol questions to authorized site personnel and document the response path.
Authorized Site-Review Handoff
Prepare the candidate record, contact history, reported responses, scheduling context where permitted, and open items for site review.
Prescreening Is Not the Same as Screening
Preliminary prescreening collects and documents candidate-reported information using site-approved questions. Unclear clinical or protocol issues are escalated, and the record is prepared for authorized site review.
The research site retains clinical interpretation, formal screening, eligibility decisions, informed consent, protocol oversight, investigator responsibility, and randomization decisions throughout the referral to randomization pathway. This separation is part of a clearly defined enrollment operations model.
Who This Helps
Research Sites
Reduce coordinator burden and improve referral readiness before screening.
Site Networks
Create more consistent prescreening workflows across locations.
Enrollment Operations Teams
Identify where candidates slow down before they reach formal screening.
Sponsors and CRO Partners
Support cleaner site workflows without relying only on more referrals.
What Structured Prescreening Organizes
- Consistent collection of candidate-reported information through site-approved questions
- Documented contact history, current status, unresolved items, and next actions
- Clear escalation of clinical and protocol questions to authorized site personnel
- Structured handoff records prepared for formal site review
- A defined boundary between preliminary operational support and formal screening
Evaluate Your Prescreening Process
A focused alignment call can review preliminary questions, documentation, status definitions, escalation, and handoff into authorized site review.
Schedule a CallProprietary Framework
The C2R Enrollment Pathway Framework™
The C2R Enrollment Pathway Framework™ maps the operational pathway from initial candidate contact through site-controlled study entry. Consent2Randomize supports Intake, Preliminary Prescreening, and Site Handoff through site-approved workflows. The research site retains protocol interpretation, clinical judgment, formal screening, final eligibility decisions, informed-consent discussion and documentation, investigator oversight, screening procedures, and randomization decisions.
Referral
A referral, patient inquiry, or expression of interest reaches the research site, and initial contact information is received.
Intake
Candidate-reported information is collected through a site-approved intake workflow, with missing items documented.
C2R SupportPreliminary Prescreening
Responses to site-approved preliminary questions are documented, and unresolved items are identified for authorized site review.
C2R SupportSite Handoff
An organized record, documented open items, and appointment-preparation details are transferred to authorized research-site personnel.
C2R SupportSite Review
Authorized site personnel review the organized record, resolve open items, and determine the appropriate next step.
Consent and Screening
The research site conducts informed consent and formal protocol screening in the order required by the protocol, IRB or IEC approvals, and applicable requirements.
Randomization
The research site makes final eligibility and randomization decisions under investigator oversight.
C2R-supported stages focus on administrative consistency, candidate follow-up, documentation, and organized handoff. They do not include protocol interpretation, formal screening, eligibility decisions, informed consent, or randomization.
