BAME patients are more susceptible to and have a higher incidence to type 2 diabetes compared to the wider population. However, the under-representation of BAME patients in type 2 diabetes RCTs makes it difficult to generalise the findings of these trials, and to determine whether the treatment is beneficial for this patient group.

The study, which is also included researchers from Bristol's School of Social and Community Medicine and School for Policy Studies, was the first systematic review to address the role of language in recruiting ethnic minority patients to RCTs targeting type two diabetes. It focused on telehealth interventions, which involve remote healthcare delivery using phone, internet, or other technology, and can involve increased communication demands.
