What the CISCRP Patient Survey Data Says — and How Sites Should Respond to It

The Center for Information and Study on Clinical Research Participation has published annual survey data on patient awareness and attitudes toward clinical trial participation since 1999. The data is among the most cited in clinical research discussions about recruitment challenges, and it contains specific, actionable insights for research sites that read it carefully rather than citing the headline statistics in presentations and moving on.

The Physician Recommendation Finding

The most consistently cited CISCRP finding is that 64 percent of patients prefer to learn about clinical trial opportunities from their own physician. This preference significantly outranks every other information source: the internet, advertising, patient advocacy organizations, and hospital notices. The physician is the most trusted clinical information source in a patient's life, and that trust extends directly to clinical trial recommendations.

The implication for research sites is not subtle: the highest-return investment in patient recruitment is not advertising spend — it is building the physician outreach infrastructure that puts trial information in front of the physicians who are seeing eligible patients right now. A patient who cannot be reached by an ad can be reached by a recommendation from their doctor.

What Patients Say About Why They Do Not Participate

CISCRP survey data on patient non-participation consistently identifies awareness gaps rather than resistance as the primary reason. Most patients who are eligible for clinical trials do not know the trials exist. They are not declining to participate — they simply never received the information needed to consider it. This is a finding with direct operational implications: the recruitment problem is not primarily a messaging or persuasion problem. It is a reach problem.

What the Data Means for Site Operations

The CISCRP data supports a specific operational conclusion: physician outreach programs that systematically reach all relevant physicians in a site's geographic area — not just the physicians the PI knows personally — are addressing the primary recruitment failure mode documented by patient survey research. The patients exist. The physicians treating them exist. The gap is the outreach infrastructure that connects the research site to the physician referral network.

Sites that treat physician outreach as a passive, relationship-dependent process — waiting for physicians to call, relying on PI networks, adding outreach only when enrollment falls behind — are operating against the weight of their own recruitment data. The CISCRP numbers do not suggest that physician outreach is one component of a diversified recruitment strategy. They suggest it is the most structurally important one.
