Studies with the goal of evaluating interventions but without the use of randomization are known as quasi-experiments. Similar to randomized trials, the goal of quasi-experiments is to show that an intervention causes an effect.

This fundamental concept makes it clear that the quasi-experimental approach is used in a large number of published studies in medical informatics. Despite the fact that randomized controlled trials are typically regarded as having the highest level.
