A case-controlled study examines one group of subjects with a certain condition at the same time as another group of subjects who do not have the condition to determine if there is an association between the condition and predictor variables. A qualitative study examines individuals' expe-riences with health problems and the contexts in which the experiences occur (e.g., a group of poststroke patients and how the attitude of the therapist affected their recovery). A descriptive study looks at specific concepts such as health care workers' perceptions of infection control practices. Quality improvement is not a study but a collection of data reflecting trends and in-formation about clinical conditions and problems.
