You are welcome to attend the following Statistics and Stochastic colloquium (part of the Colloquium Series of the Department of Mathematics and Statistics) at La Trobe University.

Title: Cross-overs, stepped wedges and staircases: some recent work in longitudinal cluster randomised trials

Speaker: Dr Jessica Kasza, Monash University

Time & Date: 12:00pm Thursday 7 May 2020

Venue: zoom seminar, see the information below

Abstract:
Although individually randomised trials are the gold standard for assessing the impact of new treatments on patient outcomes, cluster randomised trials are necessary when testing the effect of healthcare provider-level changes on patient outcomes, e.g. the effect of a hospital-wide handwashing program on the number of patients who acquire infections in hospital. Cluster randomised trials often require large numbers of clusters and thus can be infeasible, but longitudinal cluster randomised trials, where clusters may switch between intervention and control, require smaller sample sizes. Cross-overs, stepped wedges and staircases are all particular variants of longitudinal cluster randomised trials that are being conducted with increasing frequency. However, many of the underlying statistical aspects of these designs remain under-explored. In this talk I’ll discuss some of the work my group has been doing to increase our understanding of these trials and develop more trial designs, including our development of tools that allow researchers to directly apply our results.

Sincerely yours,
Statistics Seminar Convenor
