It also examines the effectiveness of different types of intervention. The term is used across a range of social and medical practices, including health care, child protection and law enforcement.

The type of intervention used depended on the situation, the number of people involved, and their proximity to the event. One form of intervention was a three-step approach, whereas different approaches include as many as five stages. [citation needed] However, the exact number of steps is not what is important for the intervention's success.
A quasi-experiment is an empirical study used to estimate the causal impact of an intervention. Quasi-experiments shares similarities with experiments or randomized controlled trials, but specifically lack random assignment to treatment or control. Instead, quasi-experimental designs typically allow assignment to treatment condition to proceed ...
The difference-in-difference (or double difference) estimator calculates the difference in the change in the outcome over time for treatment and comparison groups, thus utilizing data collected at baseline for both groups and a second round of data collected at end-line, after implementation of the intervention, which may be years later.
For example, in a case where a driver rear-ended another car due to faulty brakes, and is sued by the accident victim, the driver may decide to implead the repair shop where the brakes were worked on because the driver's liability derives from the repair shop's liability for their faulty repair of the brakes.

The second two levels form a taxonomy in which each intervention is grouped into 27 classes, and each class is grouped into six domains. An intent of this structure is to make it easier for a nurse to select an intervention for the situation, and to use a computer to describe the intervention in terms of standardized labels for classes and domains.
A clinical control group can be a placebo arm or it can involve an old method used to address a clinical outcome when testing a new idea. For example in a study released by the British Medical Journal, in 1995 studying the effects of strict blood pressure control versus more relaxed blood pressure control in diabetic patients, the clinical control group was the diabetic patients that did not ...
