Pilot randomised controlled trial: protocol changes

The current protocol is version 4.2 (dated 14 June 2018).

The general practice database search criteria included refining the search to patient postal codes within 2 miles of the participating CHEMIST CP. Feedback from several general practices suggested that this particular search criteria was complex and time-consuming for practice staff to implement, resulting in some general practices withdrawing their initial involvement in the study. So as not to exclude patients from receiving information about the study owing to the practicalities of conducting searches on general practice systems, this postal code restriction was removed from the search criteria in month 5 of recruitment.

A request to extend the pilot RCT recruitment period by 9 months was submitted to the funder after the study had been recruiting for 9 months (excluding a 3-month delay to the start of recruitment). Both costed and non-costed extension requests were rejected by the funder. Given that recruitment had continued for a longer period of time (14 months) than had been initially planned (8 months), a time-only extension was subsequently approved to allow collection of planned data for all those participants recruited to the pilot RCT (n = 44). The full study was, therefore, extended by 7 months.
