I'm doing a webinar in two weeks (15 Oct 1-2pm BST), part of NIHR Research Support Service's Methods Academy series, on the age-old question: should I do a stepped wedge trial?

Free registration, details here: tinyurl.com/z6cjvce3

Excellent three days in Bristol as part of the #BOASTiC (Bristol Oxford Aberdeen Surgical Trials Course). We've enjoyed the in-depth look at surgical trials with delegates designing their own studies by the end of the 3rd day! @marionkcampbell.bsky.social @situ-oxford.bsky.social

The measure can help highlight how an intervention may need to be improved ahead of full evaluation 7/7

Constructs include affective attitude (how someone feels about the intervention), burden, ethicality, intervention coherence (understanding of how the intervention works), opportunity costs, perceived effectiveness, & self-efficacy (one’s confidence that they can use it). 6/7

marionkcampbell.bsky.social
Assessment of acceptability can be explored through multiple approaches eg via qualitative interviews or focus groups, via questionnaires or via proxy measures eg consent rates 4/7

The MRC complex intervention framework gives a useful summary of the range of people whose views should be considered. It also encourages adopting a diverse approach. 3/7

This is particularly the case when planning for the evaluation of complex interventions as they are often multi-faceted and involve/impact many different parties (including at patient, professional and system levels) 2/7

marionkcampbell.bsky.social
One of the key things to address when undertaking a feasibility study ahead of a trial is the acceptability of different aspects of the proposed trial (intervention, trial processes, proposed outcomes etc) to all relevant parties 1/7

Statisticians are central to patient safety in clinical trials.

From designing stopping rules to monitoring adverse events, we ensure risks are detected early - protecting participants while maintaining trial integrity.

The use of Bayesian methods in the design of trials and the analysis of the findings provides several potential benefits, which may be particularly applicable in Trauma & Orthopaedic surgery.

A recent paper in the BMJ (by Ying et al) is a good read - with worked examples, tables and code to help calculate an appropriate pilot sample size. It also stresses the importance of aligning sample sizes with the objectives of the pilot study 6/6

marionkcampbell.bsky.social
There are a number of papers outlining approaches to pilot study sample size calculations - from rules of thumb (eg Julious) to ones based on estimating precision of standard deviations eg Sim & Lewis 5/6
Julious: onlinelibrary.wiley.com/doi/10.1002/...
