Abstract:
|
Special design issues arise when adapting ongoing data gathering systems for quick turn-around assessments, for example during public health emergencies. One of these issues is determining adequate sample size for subgroup estimates. For example, if a comparison between overlapping population subgroups is desired (e.g., when comparing a state coverage rate to one of its region's), special consideration must be given to the overlap when determining sample size requirements. The need to estimate influenza vaccination coverage, in the context of adapting CDC's Behavioral Risk Factor Surveillance System (BRFSS), is used to illustrate these issues and their resolution.
