Numbers provided are of patients. Each patient saw 2–5 health-care professionals; total number of recordings analyzed was therefore upward of 168 (84 × 2).
b
Center B’s second feedback session only involved individual feedback to two recruiters as the center was recruiting well; one new research nurse (n=12) and one surgeon, who had particular concerns regarding consent rates/withdrawals in two specific clinics (n=7), and all the relevant recordings were analyzed (n=19).
