Experimental and quasi-experimental designs in implementation research

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

Experimental and quasi-experimental designs for evaluating guideline implementation strategies.

The choice of study design for guideline implementation studies will determine the confidence with which the observed effects can be attributed to the interventions under study. In general, cluster randomized trials, of which there are different types, provide the most robust design. However, the use of these designs has implications for the power, conduct and analysis of studies. Wherever poss...

Quasi-Experimental designs for quality improvement research

Presentation Quality Improvement (QI) research may be defined as “the design, development and evaluation of complex interventions aimed at the re-design of health care systems to produce improved outcomes”. The challenge of QI lies in bridging the gap between knowing what needs to happen at an individual patient level and implementing this at a systems level. The inherent complexity of systems ...

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
