Patient Recruitment in Clinical Trials - Challenges and Best Strategies

The success of medical research depends on patient recruitment in clinical trials, which provides crucial insights into the safety and effectiveness of new treatments and drugs. However, many clinical trials fail due to recruitment challenges, resulting in increased costs and delays in the drug development process. Clinical trial recruitment strategies are essential to address this issue, and advancements in AI technology have created new opportunities to improve enrollment efforts.

In this article, we'll explore patient recruitment challenges, why clinical trials fail, and the best recruitment strategies for clinical research success. We will also describe how iSwarm, an EPAM AI tool, can help researchers overcome these challenges and recruit the right participants for their studies.

Why Clinical Trials Fail

Clinical trials can fail for various reasons. Here are some of the most common ones:

• Issues with the study design

• Safety concerns

• Lack of efficacy

• Unexpected results

• Insufficient funding

• Regulatory hurdles

• Operational challenges

• Patient recruitment and retention

According to the National Library of Medicine report, patient recruitment and retention are the main obstacles to the success of clinical trials. Recruiting participants within the defined time frame is the main bottleneck in conducting clinical trials. An inadequate enrollment process causes missed deadlines, increased costs, and delays of up to six months, which can cost the pharmaceutical industry millions of dollars per day. Patient recruitment takes up to 30% of development timelines, with ~1.2 billion USD spent on this activity.

And even when patient recruitment is successfully performed, the issue of patient retention remains. It is another great challenge in clinical trials as participants dropping out of the study before completion can lead to reduced statistical power, increased costs, and delays. Strategies such as improving communication, providing support, and reducing the burden on participants can improve patient retention.

Obviously, the success of a clinical trial relies heavily on a well-performed patient recruitment process. Let us look closely at why it remains such a challenging task and how pharmaceutical companies and other involved parties can overcome it.

Most Common Recruitment Challenges

There are numerous obstacles trial teams face when trying to recruit patients for clinical trials. Even when eligible patients are identified, they are sometimes not willing to participate. This is because of various reasons such as lack of awareness, fear of the unknown, lack of trust, inconvenient study location or time commitment, etc. As a result, recruitment timelines can be delayed, leading to increased costs and potentially impacting the overall success of the study.

Here are the top 5 challenges:

1. Participant Awareness and Interest: Low public awareness and interest in clinical trials can make it difficult to attract a sufficient number of participants and reach the recruitment targets.

2. Inclusion and Exclusion Criteria: Strict inclusion and exclusion criteria can limit the number of eligible participants, leading to recruitment difficulties.

3. Physician Referrals: Physicians may be hesitant to refer patients to clinical trials due to a lack of time, resources, or perceived risks.

4. Geographical Barriers: Limited access to clinical research sites or transportation difficulties can make enrolling eligible patients challenging.

5. Patient Burden: The burden of participating in a clinical trial, such as frequent visits, complex procedures, and lifestyle changes, can deter potential participants from enrolling.

With a significant proportion of clinical study sites failing to enroll participants, recruitment strategies must be prioritized from the beginning and addressed throughout the study's duration.

Best Clinical Trial Recruitment Strategies

Several strategies can be used to improve patient recruitment in clinical trials. Here are some of the most efficient ones:

Patient-Centric Approach

By placing patients' needs and comfort at the center of the study, clinical trial recruitment can be made more attractive to potential participants. This approach includes providing adequate support, clear communication, and minimal patient burden.

Digital Marketing and Social Media

Digital marketing and social media platforms can be used to advertise clinical trials and reach a broader audience, increasing participant awareness and engagement. It also helps target specific demographics and engage with potential participants, creating a more personalized and practical recruitment experience.

Collaboration with Patient Advocates

Partnering with patient advocacy groups can help in reaching out to their members and networks, who are more likely to express interest in clinical trial participation. Collaborating with them can also provide valuable insights into patient perspectives and needs, which can help design patient-friendly protocols and improve trial recruitment and retention.

Use of Electronic Health Record (EHR)

Provided compliance with specific regulations and guidelines is ensured, EHRs can be used to identify potential participants that meet the inclusion criteria for a clinical trial, reducing recruitment costs and time. It can also help in reducing the chances of enrolling ineligible patients, improving the efficiency and accuracy of recruitment.

Patient Recruitment Companies

These companies specialize in designing and executing enrollment campaigns that can reach a larger pool of potential participants, leading to faster enrollment and increased retention rates. A recruitment agency often uses various enrollment methods, including database-driven recruitment, social media advertising, and direct mail campaigns.

Technology As a Solution to Reach Recruitment Goals

Technology and artificial intelligence (AI) in particular can aid in patient recruitment for clinical trials in different ways:

• Predictive analytics: AI algorithms can help identify potential participants who meet the study's eligibility criteria by analyzing electronic health records (EHRs) and other health data.

• Chatbots and virtual assistants: Potential participants can receive real-time answers to their questions, reducing the burden on clinical staff and improving the participant experience.

• Sentiment analysis: AI-powered sentiment analysis tools can help researchers monitor social media and other online channels for participant feedback, allowing them to quickly address any concerns or issues.

EPAM Software Solution for Clinical Trial Recruitment

iSwarm is a sentiment analysis software developed by EPAM that can help with patient recruitment by analyzing social media and other online platforms. By leveraging data-driven insights, iSwarm identifies potential trial participants and assesses their interest in the study. The solution offers real-time, strategically planned marketing and social media campaigns that employ hyper-targeted multi-channel outreach. This way iSwarm supports trial sponsors in their recruitment efforts while at the same time, it helps to connect patients with research opportunities that can bring them potential benefits.

iSwarm Approach to Providing the Right Patient Population

These are the main phases through which iSwarm helps improve patient enrollment:

1. Target audience: The target audience is defined based on the inclusion and exclusion criteria and recruitment goals.

2. Listen: In order to categorize potential patient population, iSwarm’s listening algorithm analyzes and classifies massive amounts of real-time data.

3. Qualify: This step identifies interested potential patients who are open to learning about new products via online channels and social networks.

4. Build: It is necessary now to create campaign assets and outreach materials for patient engagement.

5. Activate: When everything is ready, it is time to select the campaign engagement approach in order to direct qualified audiences to the appropriate call-to-action.

Through prequalified, hyper-targeted online and social media campaigns iSwarm helps trial teams achieve their recruitment targets.

In Conclusion

In conclusion, clinical trial recruitment is a critical component of the drug development process, and its success is essential for bringing new treatments to patients in a timely manner.
