Studies Within a Trial (SWATs)

Athough there are an ever increasing number of research studies being undertaken, there isn’t very much evidence regarding the best way to conduct studies in order to ensure they can be completed successfully and are efficient.

Studies Within a Trial (SWATs) are studies embedded in clinical trials that aim to provide more evidence about the best way to conduct these trials. They produce better evidence to manage and problem solve uncertainties faced in running future trials, for example in relation to recruitment and retention of participants.

The PCTU actively encourages investigators to embed SWATs in their trial design. For more information, please visit our SWATs page.
