Have you ever had trouble enrolling patients for a study? If you answered “yes” then you’re not alone. Most trials end up having to double their original timelines to meet enrollment goals, and 48% of sites under-enroll study volunteers. These delays in drug development cost a lot of money, but when it comes to finding the right participants, patient recruitment is easier said than done.

Take a look at the infographic below to see how people find out about clinical trials, important factors in choosing to participate, top perceived benefits and risks, challenges associated with enrollment, and more.

  1. Really neat infographic – please email more as you develop. Very informative in minimal pages/time

    1. Hi Moorthy,

      Thanks for the comment! Can you clarify what you mean by presentable format?


      1. Great infographic indeed. Think Moorthy might mean in a slide format or the like. The size of the graphic of a PPT slide makes it quite small. Would be really keen to use it in our efforts, with credit provided.

  2. Hi Kristina, very interesting and demonstrative! Am I allowed to use it in our newsletter for the investigators?

  3. Re:Infographic. It would make a great poster for promoting clinical trials at public forums. Can you covert it pdf at high enough resolution for poster size prints? (slides would be useful for our clinical staff and investigators). Many thanks and much Mahalo! (“Thank You” in Hawaiian)

  4. Hi Kristina,

    This is a very interesting insight. May I know which markets/countries does this statistical data refer to?


    1. Hi Panha,

      Thanks for the comment! The data used in this infographic is obtained from the sources in the reference list (also below). Each statistic corresponds to one of the sources, as indicated by the number that appears in superscript. I know within each CISCRP study, there is a breakdown by region of survey respondents. I used the overall percentages, but you can see it broken down by the different demographics of respondents if you go to the links below.

      Hope that helps!


  5. Thank you for the well-structured infographic! Patient recruitment is a tough process, but it can be optimized in a variety of ways. Knowing your target patients, keeping trial volunteers well-informed about the latest updates about the clinical trial, using a user-friendly clinical trial management system are just some of the things which can facilitate the process of clinical trial recruitment. A few other very useful tips for optimization of patient recruitment are described in the following article:
