Cluster Randomized Trials

AAP Grand Rounds, 2011
Over the last century, the randomized clinical trial has become the gold standard for interventional studies. Typically individuals are randomly assigned to an experimental group or a control group. What if it was impractical or unethical to randomize individuals to a treatment group? This is where the cluster randomized trial design comes in.

Balance in cluster randomized trials

Statistics in Medicine, 2001
This paper explores the role of balancing covariates between treatment groups in the design of cluster randomized trials. General expressions are obtained for two criteria to evaluate designs for parallel group studies with two treatments. The first is the variance of the estimated treatment effect and the second is the extent to which the estimated ...

Cluster-randomized trials: A closer look

Clinical Trials, 2016
Background: The cluster-randomized trial is the methodology of choice for evaluating interventions administered at the group level such as public health and healthcare quality improvement interventions. Because of unique features of this design, it can be difficult to apply standard research ethics guidelines to cluster-randomized trials.

Cluster Randomized Trials:Another Look

Hastings Center Report, 2013
The type of research known as cluster randomized trials raises ethical questions not readily answered within the standard understanding of research ethics. What distinguishes a CRT is that it randomizes at the level of social groups rather than at the level of individual research participants: in a CRT, the regimen under study might be assigned to a ...

Cluster Randomized Clinical Trials

2017
This chapter discusses the design and analysis of cluster randomized clinical trials (CRCTs). These trials are useful when the intervention is most appropriately applied at a group level (e.g., provider, clinic, hospital). Since patients within a provider, clinic, or hospital are more likely to be similar than patients from another provider, clinic, or
