Robust inference for the stepped wedge design

open access: yesBiometrics, 2019
AbstractStepped wedge designed trials are a type of cluster‐randomized study in which the intervention is introduced to each cluster in a random order over time. This design is often used to assess the effect of a new intervention as it is rolled out across a series of clinics or communities.

Sample size considerations for stepped wedge designs with subclusters

open access: yesBiometrics, 2021
AbstractThe stepped wedge cluster randomized trial (SW‐CRT) is an increasingly popular design for evaluating health service delivery or policy interventions. An essential consideration of this design is the need to account for both within‐period and between‐period correlations in sample size calculations.

The hunt for efficient, incomplete designs for stepped wedge trials with continuous recruitment and continuous outcome measures

open access: yesBMC Medical Research Methodology, 2020
Background We consider the design of stepped wedge trials with continuous recruitment and continuous outcome measures. Suppose we recruit from a fixed number of clusters where eligible participants present continuously, and suppose we have fine control ...
