The inefficiency induced by between-cluster variation in cluster randomized (CR) trials can be reduced by implementing a crossover (CO) design. In a simple CO trial, each subject receives each ...

A tailored approach with rapid needs assessment before and during implementation to address local testing site barriers in ...

Objectives: Cluster randomised trials, in which groups of individuals are randomised, are increasingly being used in the health field. Adopting a clustered approach has implications for the design of ...

A cluster randomised trial (CRT) is a randomised controlled trial in which pre-existing groups, called clusters, of individuals are randomly allocated to treatment arms. For example, clusters may be ...

Cluster randomized trials (CRTs) represent a pivotal design in evaluating public health and clinical interventions where individuals are grouped into clusters (such as schools, hospitals or ...

The Stepped Wedge Cluster Randomized Trial is a research methodology that has been growing in popularity, particularly for pragmatic implementation and dissemination trials. SW-CRTs can have ...

We performed a cluster-randomized trial of universal decolonization as compared with routine-care bathing in nursing homes. The trial included an 18-month baseline period and an 18-month intervention ...

The randomization of GPs to the intervention or control arm will be conducted externally by the coordinating centre of the study in Greifswald. GPs consenting to participate are reported by the two ...

Injuries from falls are major contributors to complications and death in older adults. Despite evidence from efficacy trials that many falls can be prevented, rates of falls resulting in injury have ...

Background: We developed and tested a new method, called the Evidence-based Practice for Improving Quality method, for continuous quality improvement. Methods: We used cluster randomization to assign ...
