randomizing intact social units (e.g. families, schools, communities) rather
than independent individuals in experimental trials. Reasons are diverse,
but include administrative convenience, a desire to reduce the effect of
treatment contamination and the need to avoid ethical issues which might
otherwise arise. Dependencies among cluster members typical of such designs
must be considered when determining sample size and analysing the resulting
data. Failure to adjust standard statistical methods for within-cluster
dependencies may result in severely underpowered studies and in spuriously
elevated Type I error rates. The purpose of this talk is to review the key
issues in the design and analysis of cluster randomization trials. These
ideas will be illustrated using data from several recently completed
studies.

ABSTRACT
It is becoming increasingly common for health researchers to considerrandomizing intact social units (e.g. families, schools, communities) rather
than independent individuals in experimental trials. Reasons are diverse,
but include administrative convenience, a desire to reduce the effect of
treatment contamination and the need to avoid ethical issues which might
otherwise arise. Dependencies among cluster members typical of such designs
must be considered when determining sample size and analysing the resulting
data. Failure to adjust standard statistical methods for within-cluster
dependencies may result in severely underpowered studies and in spuriously
elevated Type I error rates. The purpose of this talk is to review the key
issues in the design and analysis of cluster randomization trials. These
ideas will be illustrated using data from several recently completed
studies.
