AI Hub pilot with Trialwell: Usability evaluation of the Trialwell web platform to recruit participants for clinical and non-clinical trials

Trialwell supports researches by recruiting appropriate participants. AI Hub conducted a pilot study with Trialwell to evaluate their webservice with potential participants. The mission of AI Hub is to provide Aritifical Intelligence (AI) related guidance for small and medium sized companies (SMEs) free of charge. Since Trialwell will use AI to match participants’ profile with appropriate research trial, AI Hub agreed to conduct a pilot project to evaluate the usability and usefulness of the system.

We started discussing about the pilot officially on 9th April 2021, where Trialwell shared their expectations with us. In addition, we got a clear understanding about the service and it’s needs. Trialwell aims to recruit participants on behalf of clinical and non-clinical research trials. Researchers need to make arrangements with Trialwell to look for participants on their behalf. Our goal was to evaluate the usability and usefulness of the service with both researchers, who want to recruit participants, and potential end-users enrolling to the trials.

We recruited 2 researchers and 2 potential end-users for the user study. The researchers belonged to the faculty of ITC. One male and one female participated, aged between 30-40 years. The potential participants were male and female aged between 55-65 years. We provided different tasks for these two user groups since our target was to evaluate both researcher’s and end user’s perspective. We introduced Trialwell service for them and provided few tasks to be conducted with the service. Afterwards, we asked them few questions regarding the service.

Overall, the service got 4/5 points from the participants. Some usability issues were revealed in the study. The users found the service useful and they commented that they could use it in the future. One participant mentioned: “Can we get free subscriptions? Haha!”. Researchers suggested that it would be a great if Trialwell could handle consent forms and management of participants. Trialwell found our findings useful and they commented that they will consider the feedbacks from the participants in their next iteration.

Doctoral Researcher Aparajita Chowdhury and University Lecturer Aino Ahtinen (AI Hub wp4) conducted this pilot project along with the Trialwell team. Special thanks for the Trialwell team for this great collaboration!
