Clinical Trial Recruitment Strategies to Accelerate Patient Enrollment

Patient recruitment is one of the most challenging areas in clinical trials. And one of the most common reasons is overly optimistic projections regarding the pool of available patients. So common is this perception that it’s been given a name: Lasagna’s Law.

According to Lasagna’s Law, the number of available patients who meet the inclusion criteria sharply decreases when a clinical trial begins, by about 90%, and only reappears when the trial is completed.

According to an article in Contemporary Clinical Trials Communications, almost 90% of clinical trials experience significant delays due to patient recruitment issues, and over 75% of terminated clinical trials are due to poor recruitment.

Fortunately, because of these challenges, clinical trial recruitment strategies have emerged to help researchers optimize patient recruitment. Here, we’ll uncover some of the top contenders.

Why Clinical Trial Recruitment Matters

A lack of clinical trial enrollment and retention may result in extended trial durations, leading to additional costs and resource allocation. It can also jeopardize the study due to an inadequate sample size. Failure to recruit the required number of eligible participants can result in reduced validity, significant delays, and financial losses.

The good news: A study documenting patient recruitment tactics found that, when clinical trial recruitment strategies were integrated into the initial study design, using both direct and indirect methods, the research team met its enrollment target within the allotted time.

Leveraging Digital Channels for Patient Outreach

Digital advertising reaches patients where they are, whether on Facebook, Instagram, or email. It enables you to target specific patient groups based on health behaviors, age, or location. For instance, a campaign targeting individuals with rheumatoid arthritis could focus on social media groups and online forums where this population is actively engaged.

Retargeting presents the information to the same patient multiple times. When performed correctly, leveraging digital channels can accelerate the recruitment of suitable participants.

Social Media Advertising

When utilizing social media, it’s essential to know which platform the target market uses. For example, older demographics tend to spend more time on Facebook, while younger generations are more likely to be found on Instagram, YouTube, and TikTok.

Dynamic content, such as videos, can help viewers understand the study better and increase their interest, while recruiters can base data-informed decisions on engagement. One group that recruited participants for a trial of web-based smoking interventions recruited almost half of the participants (49%) from Facebook.

Search Engine Marketing

Search engine marketing is one of the most powerful tools in digital advertising. It uses organic strategies and paid ads to connect to people interested in relevant information. Recruiters can reach specific populations who have been searching for certain keywords related to the clinical trial or medical condition on Google.

Another popular clinical trial recruitment strategy is using Search Engine Optimization (SEO) to increase leads and enhance a trial’s online presence, thereby attracting potential participants.

Patient Matching Platforms

Patient matching platforms are also powerful tools that help recruiters find patients who are actively seeking clinical trials. The platforms enable patients to search by location, medical condition, or other factors. By connecting with these platforms, recruiters can directly engage with individuals who have shown interest in patient recruitment.

Combining Traditional Approaches with Modern Tactics

When considering how to recruit patients for clinical trials, it’s easy to overlook traditional methods in this digital age. However, conventional approaches to trial participant recruitment have their place. The best approach is to combine the two, maximizing engagement and in-person interaction.

Healthcare Provider Networks

In the previously mentioned study, in-person recruitment was the most cost-effective clinical trial recruitment strategy, followed by personal referrals. A healthcare provider network gives researchers access to physicians who can directly refer eligible patients.

Patient Advocacy Group Partnerships

Partnering with a patient advocacy group provides access to large online communities. If endorsed by them, your trial gains the backing of a trusted source, offering an excellent opportunity to reach motivated and relevant patient populations.

Traditional Media

Traditional marketing approaches include flyers, television, radio, and newspapers. Flyers have yielded a high number of enrollments due to the ability to place them in high-traffic areas frequented by the target demographic. This placement may be in community centers, clinics, libraries, and senior centers. While television and radio offer a broad reach, their targeting is less direct than that of other methods.

Next-Generation Recruitment Strategies

Artificial intelligence (AI) has become increasingly indispensable to the healthcare industry, and clinical trials are no exception. AI-powered natural language processing analyzes EHR data for feasible patient outreach and recruitment. Some platforms apply machine learning for data analysis, optimizing recruitment and retention rates.

According to a narrative review published in the International Journal of Medical Informatics, clinical trial enrollment rates improved by 65% when AI-powered recruitment tools were used.

Optimizing the Patient Experience with Patient-Centric Recruitment and Retention

Patient-centric recruitment centers on direct conversations with the patient, whether in-person or virtual. It involves explaining the risks and benefits, and providing adequate support, while presenting the study and expectations in a manner they can understand.

Patients tend to shy away from overly complex studies that are difficult to understand or require multiple follow-ups.

Measuring and Optimizing Recruitment Performance

Several key metrics help evaluate patient recruitment campaigns. Evaluating these metrics on an ongoing basis enables recruiters to prevent delays, meet enrollment goals, and maximize ROI.

• Determine which campaign is performing the best.
• Keep an eye on how many referrals are making their way to informed consent and the leading recruitment source.
• Explore why referrals fail pre-screening.
• Determine the cost per qualified patient and identify the most efficient outreach channel.

How Medical Answering Services Support Clinical Trial Success

When a potential participant reaches out through social media or a trial’s website, a medical answering service can conduct in-depth screening. This screening involves assessing their eligibility, which may include questions about their medical history and lifestyle. When someone meets the study’s criteria, they are scheduled for a follow-up appointment.

But how do they ensure HIPAA compliance when dealing with sensitive patient information?

At notifyMD®, we are the first answering service to obtain HITRUST certification, the gold standard in patient data protection. With over 30 years of experience in the healthcare industry, you can rely on our virtual assistants to streamline the enrollment process and provide engaging, supportive, and empathetic guidance.
