Boost Clinical Trial Recruitment & Retention with Zelthy

Recruiting and retaining patients in clinical trials remains a major challenge in medical research. According to the U.S. Food and Drug Administration (FDA), nearly 30% of clinical trials fail to recruit a single participant, while 85% face delays due to recruitment issues. Even after enrollment, retention is a significant hurdle with reports indicating dropout rates of 15-40%.

These challenges not only delay the development of life-saving treatments but also increase trial costs and hinder medical advancements. To improve clinical trial success, sponsors and researchers must adopt innovative strategies to enhance patient enrollment and ensure participant retention.

In this article, we explore 10 proven strategies to boost patient recruitment and retention, drawing from industry best practices and research-driven insights to optimize trial outcomes.

Adopt a Patient-Centric Approach in Trial Design and Execution

A patient-centric approach makes clinical trials more accessible and engaging. To improve recruitment and retention, focus on:

• Understanding Patient Needs: Consider their daily challenges, medical conditions, and lifestyle.

• Reducing Barriers to Participation: Minimize travel, offer remote options, and simplify procedures.

• Enhancing Patient Experience: Provide clear communication, flexible scheduling, and personalized support.

• Involving Patients in Trial Design: Work with patient advocacy groups to ensure the study aligns with real-world needs.

By prioritizing the patient voice, trials become more relevant, leading to higher enrollment and retention rates.

Leverage Technology and Digital Platforms

Technology makes patient recruitment and retention more efficient by meeting patients where they are—online.

• Expand Reach: Use social media, targeted ads, and online registries to attract participants.

• Enhance Engagement: Leverage email campaigns, mobile apps, and telemedicine for ongoing communication.

• Improve Retention: Utilize ePRO, wearable devices, and digital reminders to track progress and support patients.

With over 3.5 billion social media users, digital outreach is a powerful tool to boost trial participation and ensure study completion.

Prioritize Clear and Transparent Communication

Effective communication builds trust and improves both patient recruitment and retention.

• Simplify Informed Consent: Many consent forms are written at a 12th-grade level, while the average adult reads at an 8th-grade level, leading to confusion. Studies show that for each additional grade level increase in readability complexity, dropout rates rise by 16%.

• Set Clear Expectations: Outline trial details, benefits, risks, and commitments upfront.

• Address Concerns Proactively: Foster open communication and provide ongoing support.

When patients feel well-informed and confident, they are more likely to enroll and stay engaged throughout the trial.

Meet Patients Where They Are-Online and Offline

Reaching patients effectively requires a strategic outreach plan that engages them in both digital and real-world spaces.

• Online Engagement: Utilize social media platforms, patient communities, and targeted digital outreach to connect with potential participants.

• Community Partnerships: Collaborate with patient organizations, advocates, and local healthcare providers to build trust and credibility.

• In-Person Outreach: Host informational sessions at clinics, hospitals, and community centers to educate and engage patients.

By meeting patients where they already are, both online and offline, trials can increase awareness, recruitment, and long-term participation.

Address Logistical Barriers and Provide Support

Logistical challenges like transportation, financial constraints, and time commitments can discourage participation in clinical trials. To minimize burden and improve retention, consider:

• Covering Travel Costs: Offer transportation support, stipends, or reimbursement for study visits.

• Flexible Scheduling: Provide weekend, evening, or remote visit options to accommodate patients' availability.

• Reducing Site Visits: Use remote participation, telemedicine, and point-of-care testing (POCT) to limit unnecessary travel.

• Providing Compensation: Offer incentives for time and effort, helping ease financial concerns.

By removing logistical barriers, trials become more accessible, leading to higher recruitment and retention rates.

Don’t Forget Families and Care Partners

For many patients, care partners and family members play a crucial role in decision-making and ongoing participation.

• Engage Care Partners Early: Recruitment materials should address both patients and their loved ones, especially for conditions requiring caregiver support.

• Provide Family-Friendly Resources: Offer educational materials to help them understand the trial process and expectations.

• Train Site Staff: Ensure teams are prepared to answer caregiver concerns and provide ongoing support.

By supporting families and care partners, trials can improve enrollment, retention, and overall patient experience.

Provide Incentives and Show Appreciation

Recognizing and rewarding participants helps boost both recruitment and retention in clinical trials.

• Offer Meaningful Incentives: Provide compensation, travel reimbursement, and flexible participation options to ease burdens.

• Highlight the Impact: Emphasize altruism and contributions to medical research, reinforcing the value of their participation.

• Show Appreciation: Use thank-you notes, milestone achievement cards, and regular updates to keep participants engaged.

• Celebrate Milestones: Recognize study progress and participant dedication to foster motivation and long-term commitment.

By making patients feel valued, trials can improve engagement, satisfaction, and retention rates.

Build Relationships with Patient Organizations and Clinicians

Strong partnerships with patient advocacy groups and healthcare providers can enhance recruitment and retention efforts.

• Engage Patient Advocacy Groups: Work with patient organizations to understand participant needs and tailor outreach strategies.

• Leverage Trusted Physicians: Clinicians can refer eligible patients, increasing trust and trial enrollment.

• Create Referral Programs: Develop collaborations with research networks and patient registries to streamline recruitment.

• Start Early: Build long-term relationships with advocacy groups and providers before launching a study.

By partnering with trusted sources, trials gain credibility, wider reach, and improved patient retention.

Create a Feedback Loop and Listen to Patient Sentiment

Regular patient feedback helps improve the trial experience and boost retention rates.

• Use Surveys & Check-Ins: Collect feedback after site visits, mid-trial, and post-study to identify concerns early.

• Address Issues Promptly: Act on feedback to resolve communication gaps and logistical challenges.

• Leverage Sentiment Analysis: Use insights management tools to track patient sentiment and improve engagement.

By listening to participants, trials can enhance patient satisfaction, trust, and long-term commitment.

Stay Top-of-Mind and Offer Reminders

Consistent follow-up communication helps improve enrollment and retention by keeping patients engaged.

• Reach Out to Unresponsive Patients: A simple follow-up call or email can encourage enrollment.

• Send Timely Reminders: Use text messages, phone calls, or emails for appointment reminders and study updates.

• Leverage Retargeting: Digital ads and automated messages can re-engage interested participants.

By helping patients manage their schedules, trials can reduce dropouts and improve completion rates.
