Prescreening Workflows for Research Sites
A prescreening workflow is the operational system that moves candidates from intake receipt to site handoff. Without a defined workflow, prescreening quality depends on individual staff performance rather than process design, producing inconsistent documentation and variable record quality. Structured workflows standardize prescreening documentation and support more consistent enrollment operations.
What a Prescreening Workflow Includes
A prescreening workflow is more than a checklist. It is the complete operational system governing how candidates are received from intake, how site-approved questions are asked, how candidate-reported information is documented, and how candidates whose records are ready are prepared for site handoff. Each component of the workflow connects to the next, and gaps in any component produce gaps in prescreening output quality.
The core components of a prescreening workflow are: a site-approved preliminary question set, a candidate contact procedure with defined follow-up steps, a set of operational status categories with corresponding next steps, documentation standards for each status, a site handoff package template, and performance metrics that measure workflow execution quality.
For a foundational understanding of what prescreening is and what it is designed to accomplish, see what is clinical trial prescreening. For related guidance on preliminary information collection, see preliminary eligibility-information collection best practices.
Building a Site-Approved Preliminary Question Set
The site-approved question set is the technical core of the prescreening workflow. It is built with the site to identify the specific questions, documentation requests, and confirmations that can be completed at the prescreening stage. The set distinguishes between questions that can be asked through structured conversation, questions that require documentation review, and questions that require clinical assessment and therefore belong at formal screening.
A well-constructed question set covers the most common non-clinical details the site wants collected before formal screening: age range, primary diagnosis, treatment history, concomitant medications, geographic availability, scheduling constraints, and general study awareness. It does not attempt to replace clinical screening, and the site remains responsible for any clinical determination.
The checklist should be reviewed at every protocol amendment and at any point where screen failure rate increases without an identifiable change in referral demographics. A checklist that reflects the current protocol version is a prerequisite for effective prescreening. For common prescreening mistakes, see common prescreening mistakes in clinical research.
The Five Stages of an Effective Prescreening Workflow
Candidate Receipt from Intake
The prescreening workflow begins when a candidate record is received from intake. At this point, the record should contain verified contact information, a completed intake form, preliminary information collected at intake, and an organized documentation package. If intake has not provided a complete record, the prescreening workflow includes a structured data completion step before site-approved questions begin.
Site-Approved Question Application
The prescreening team applies the site-approved preliminary question set to the candidate's record. Questions that can be answered from documentation are reviewed first. Questions requiring a structured conversation are identified and organized into a contact framework before outreach begins.
Structured Prescreening Contact
A trained team member contacts the candidate using the site-approved question set as the conversation guide. Each question is addressed in sequence, responses are documented in real time, and candidate questions about study requirements are addressed. The contact produces a complete summary of candidate-reported information and a noted availability status.
Outcome Documentation and Status Tracking
At the conclusion of the prescreening contact, the candidate record is updated with a structured operational status: ready for site review, information incomplete, clarification requested, or unreachable after the agreed contact attempts. Each status triggers a defined next step in the workflow.
Site Handoff Package Preparation
Candidates whose records are ready for site review advance to handoff package preparation. The package is organized according to the site's review preferences and includes the candidate-reported summary, contact history, availability confirmation, and any relevant supporting documentation.
The Site Handoff Package
The handoff package is the output that prescreening prepares for the site. Its purpose is to give coordinators organized information to begin clinical review with less information-gathering delay. A complete handoff package includes the candidate-reported summary for the pre-site questions, the contact history with timestamps, the candidate's noted availability for screening procedures, and any supporting documentation that has been collected during prescreening.
The format of the handoff package should be defined in advance and reviewed with the site to match their review preferences. Sites that receive records in a consistent, organized format can review them more efficiently than sites that receive ad hoc documentation in variable formats. This consistency is one way that prescreening workflow standardization can support coordinator capacity.

Measuring Prescreening Workflow Performance
Workflow performance is measured through a set of stage-specific metrics that reveal how consistently the workflow is being executed and where execution gaps are occurring. Key metrics include prescreening-to-screening conversion rate, prescreening follow-up step adherence, question set completion rate per contact, and time from intake receipt to prescreening outcome documentation.
Without these metrics, it is not possible to distinguish between a workflow design problem and a workflow execution problem, or between a prescreening issue and a referral quality issue. Metrics that track workflow execution quality make continuous prescreening improvement possible.
