Home › Patient Strategy & Recruitment
Turn patient intelligence into recruitment action, connecting the right patients and HCPs to your trials.
Size and locate eligible populations, map referral pathways and see how patients access care.
Connect patients to the providers and sites that serve them and identify high-volume treating HCPs.
Identify matched patients earlier and reach them through targeted HCP and patient outreach.
Understand the competitive picture. Identify where to invest and where to compete.
Design protocols real patients can qualify for, grounded in competitive evidence.
Place trials where eligible patients and capable sites meet.
Reach the right patients at the right moment.
Stay compliant and meet critical reporting obligations.
Give patients, caregivers, and HCPs the information they need, with a branded, plain-language digital presence covering your entire trial portfolio.
Build a community around your portfolio and increase awareness among the physicians treating your target population, turning interest into intent before a site ever contacts a patient.
From precision identification for complex protocols to broad network recruitment for studies that need volume, Citeline’s enrollment solutions connect identification to activation, so matches become enrollments.
Norstella, Citeline’s parent company, provides real-world patient data powered by NorstellaLinQ, sizing the eligible population, mapping referral pathways, and identifying the providers treating your target patients across claims (300M+ US lives), lab results (500M+ diagnostic results per month), EHR (62M US lives), and the Skipta network of 2M+ providers.
A secure, branded research community where patients follow trials, receive updates, and stay connected from first interest through enrollment

US lives in EHR data across 500+ hospitals and health systems
providers in the Skipta network

Every algorithm is built by Citeline's in-house clinical experts, so the logic behind each match can be explained and defended.

Deploys across 500+ hospitals and health systems and connected to 3 of the top 4 national reference labs, with no integration constraints or single-system bias.

All patient information is de-identified before reaching sites. Alerts contain only the clinical signals relevant to eligibility.
| Traditional Approach | Patient Strategy & Recruitment Workflow |
|---|---|
| Patient population sized by assumption or historical estimates | Eligible population sized and located against real-world data, so site and country strategy reflects where patients actually are |
| Recruitment strategy defined after site activation | Patient access strategy built upstream, connecting recruitment to feasibility rather than starting from scratch at site activation |
| Sites receive unfiltered patient lists to sort through manually | Sites receive only de-identified, protocol-matched alerts, with no manual chart review and no unqualified referrals |
| Screen-fail rate emerges as a problem after recruitment starts | Precision matching means lower screen-fail rates from the first alert, not after the problem has cost time and budget |
| No centralized view of recruitment performance across sites, channels, and programs | One platform gives sponsors, CROs, and sites near real-time visibility into the full referral funnel, from alert to randomization |
| Generic data sources with limited clinical depth and no in-house validation | NorstellaLinQ real-world data across claims, labs, EHR, and clinical notes, with Citeline's clinical SMEs building and validating every algorithm |
Whether you’re planning a study, rescuing one behind timeline, or building a long-term recruitment program, the right setup depends on your trial, your sites, and your population.
