Aim: Patients from racial and ethnic minority backgrounds in the USA have historically been under-represented in research trials. Understanding their viewpoints regarding participation in N-of-1 trials is imperative as we design and implement these studies. Materials & methods: We conducted six focus groups of racial and ethnic minority patients (n = 25) and providers (n = 9). We used content analysis to identify themes. Results: Our results noted the importance of considering family members in N-of-1 trial recruitment and participation, patients' desire for education as a design feature, for 'lifestyle' changes as a treatment option and for use of nonevidence-based treatments in the design of future N-of-1 trials. Conclusion: Personalized trials have the potential to change the way we deliver primary care and improve disparities for minorities.

Lay abstract Commonly, research studies seek to enroll large groups of individuals to test a new product or medication. However, the personalized trial/N-of-1 trial has a different goal. This is to focus on a single person and study their response to different treatments. Our focus group-based study of medical providers and racial and ethnic minority patients, sought to learn how personalized trials can be designed to include the life experiences and cultural considerations of members of minority populations. Participants noted factors such as the role of family, including educational programming or lifestyle changes in the trial, and the use of natural remedies (not prescribed by a physician) as specific cultural considerations. N-of-1 trials have the potential to change the way we deliver primary care and improve disparities, but we must design them to address the concerns of importance to minority populations.
