4 Quasi - experimental Designs

A tutorial on Quasi-experimental designs

A main step in answering a scientific hypothesis in an epidemiological study is deciding which type of study is suitable to be undertaken, considering methodology, practical considerations and budget and time limitations

Randomized Experiments and Quasi - Experimental Designs 5 RANDOMIZED EXPERIMENTS AND QUASI - EXPERIMENTAL DESIGNS IN EDUCATIONAL RESEARCH

A systematic review of quasi-experimental study designs in the fields of infection control and antibiotic resistance.

We performed a systematic review of articles published during a 2-year period in 4 journals in the field of infectious diseases to determine the extent to which the quasi-experimental study design is used to evaluate infection control and antibiotic resistance. We evaluated studies on the basis of the following criteria: type of quasi-experimental study design used, justification of the use of ...

Inclusion of quasi-experimental studies in systematic reviews of health systems research.

Systematic reviews of health systems research commonly limit studies for evidence synthesis to randomized controlled trials. However, well-conducted quasi-experimental studies can provide strong evidence for causal inference. With this article, we aim to stimulate and inform discussions on including quasi-experiments in systematic reviews of health systems research. We define quasi-experimental...

Position Paper: The Use and Interpretation of Quasi-Experimental Studies in Medical Informatics

Quasi-experimental study designs, often described as nonrandomized, pre-post intervention studies, are common in the medical informatics literature. Yet little has been written about the benefits and limitations of the quasi-experimental approach as applied to informatics studies. This paper outlines a relative hierarchy and nomenclature of quasi-experimental study designs that is applicable to...
