Healthy Volunteers Recruitment for a clinical study in gastroenterology (constipation)

For a research study at a university hospital, investigators needed to recruit more than 80 adults with hard stool and an overall good health. The study team could not recruit within their own patient population because this target population is typically not treated within a hospital setting or even not treated at all.

Pivotal was contracted to inform, recruit, and prescreen patients from outside the hospital pool.

Recruiting outside a hospital setting

  • The team developed a comprehensive direct-to-patient digital recruitment strategy.
  • This included an online awareness campaign with targeted advertising based on geo location, age, and gender.
  • Our team designed and launched several ads using photos, illustrations, animated videos, GIFs.
  • When clicking an ad people were redirected to a webpage for comprehensive information about the study. The webpage also included a smart online pre-screener and application form.
  • Study sites are the most important part when it comes to successfully screening and enrolling participants. Our team developed a close working relationship and trust with the site staff.

C-LYS platform

Webpage on C-Lys platform. This webpage included:

  • comprehensive information about the study
