A nurse wants to know which study design is more appropriate to study the effectiveness of an intervention like sending reminder calls to parents, public health support services, among children that need immunization. She has questions whether to use a quasi experimental cohort following the example of "Effectiveness of a Community Coalition for Improving Child Vaccination Rates in New York City" by Sarah findley et al. (1997) (see attached), or if there is another design that can be used and why. Based on that design, how will it answer the research question?
Hope this discussion on quasi experimental designs and randomized cohort study helps you understand when to use which study design in a health care setting.

Quasi experimental designs give you the flexibility of not having to select the subjects because they are "naturally" randomized. K. Moore (2008) states the information you can obtain with quasi experimental design as: "descriptive information about the population served; information that suggest whether anticipated changes are occurring; data that suggest the magnitude of the change; why does changes may occur in one group or another; and information on whether some outcomes are changing or not" (Moore, 2008, p.1) Unfortunately they cannot establish direct ...
The solution includes a discussion on quasi experimental cohort and randomized cohort study design in health care setting. Possible reseach questions and steps needed to design a study using randomized cohort study design are presented as applied to asessing children immunizations in the study group.
