Enhancing Diversity in Clinical Trials through Effective Communication




January 10, 2024


The significant challenge faced by researchers is the lack of diversity among trial participants. This underrepresentation can lead to limited generalizability and hinder the development of therapies that benefit all populations.

Starting in 2024 the FDA is requiring diversity plans for Phase III and above, this requirement will increase the need for study participants and volunteers in order to gather the necessary data for statistical relevance. Keeping in mind, researchers have traditionally struggled to meet volunteer enrollment numbers. Considering the new guidance for diversity in clinical trials, the need for research volunteers and participants will grow exponentially as the industry considers new strategies for protocol design and new strategies for inclusion/exclusion criteria.

Let’s look for simple ways to update our strategies that will result in big impacts on diversity outcomes. Starting with effective communication strategies can help bridge this gap and increase diversity in clinical trials. 

1. Tailoring language for diverse audiences: To attract a diverse pool of participants, researchers should communicate trial information using inclusive language and avoid complex scientific jargon. By using plain language and ensuring clarity, potential volunteers from different backgrounds will feel more comfortable and engaged in the trial. 

2. Engaging with culturally sensitive approaches: Understanding cultural nuances is essential in building trust and engaging diverse populations. Researchers should engage with community organizations, religious institutions, and cultural leaders to establish partnerships that can facilitate effective communication with underrepresented communities. This approach helps address cultural concerns and build rapport, ultimately increasing diversity in clinical trials. 

3. Addressing barriers to participation: Communication should address common barriers that hinder diverse populations from participating in clinical trials. For example, researchers can provide information on transportation options, childcare services, or language interpretation services to remove practical obstacles. Using services by providers such as Scout Clinical, a company which provides solutions to getting participants to the clinical trials. Using expert providers can greatly improve study diversity by proactively addressing participants concerns, making participation more accessible and inclusive. 

4. Exploring multiple communication channels: Utilizing diverse communication channels is essential to reach a wide range of potential participants. Researchers should consider using various platforms such as social media, community newsletters, local clinics, physician support, seminars, community outreach, local events, collaborations with patient centric organizations, radio, and targeted advertisements to disseminate trial information. By increasing community outreach and varying the channels of communication researchers can effectively engage diverse populations. 

5. Establishing trust through transparent communication: Building trust is paramount in increasing diversity in clinical trials. Researchers should provide clear information about the purpose, process, and potential risks and benefits of the trial. Transparent communication helps potential participants feel informed and confident in their decision to participate, thus encouraging a more diverse representation. 

6. Leveraging community ambassadors and influencers: Engaging community ambassadors and influencers who are respected and trusted within diverse communities can be highly effective. Including diversity in research center hiring plans creates safer spaces in which communities feel included. These individuals can serve as advocates, disseminating trial information, and addressing concerns in a relatable and culturally sensitive manner. Their influence can help break down barriers and increase the diversity of trial participants.

Increasing diversity in clinical trials is crucial for ensuring that medical advancements benefit all populations. Effective communication strategies play a pivotal role in engaging diverse communities and overcoming barriers to participation. By tailoring language, addressing cultural nuances, becoming part of the local community, and establishing trust, researchers can create an inclusive environment that encourages a diverse representation in clinical trials. Embracing these communication practices will lead to more accurate and applicable results, ultimately improving healthcare outcomes for everyone.
