Interventional studies can be divided broadly into two main types: (i) “controlled clinical trials” (or simply “clinical trials” or “trials”), in which individuals are assigned to one of two or more competing interventions, and (ii) “community trials” (or field trials), in which entire groups, e.g., villages, ...
Example: to study the efficacy of adding fluoride to the community water supply to prevent dental decay, two similar towns in New York State were studied in the Newburgh-Kingston water fluoridation trial (Ast et al, 19561). In one town, fluoride was added to the water supply; nothing was done to the other town.
Community-based research offers a notable advantage to smaller, independent practices primarily due to one factor: patients do not have to travel far to participate in a clinical trial, which can boost enrollment and advance scientific knowledge.
(KLIH-nih-kul STUH-dee) A type of research study that tests how well new medical approaches work in people. These studies test new methods of screening, prevention, diagnosis, or treatment of a disease.
NIH Definition of a Clinical Trial A research study in which one or more human subjects are prospectively assigned to one or more interventions (which may include placebo or other control) to evaluate the effects of those interventions on health-related biomedical or behavioral outcomes.
Definition: Clinical trials are interventional studies and involve investigational medicinal products, whereas clinical studies can include both interventional and non-interventional studies but do not involve investigational medicinal products.
Clinical trials typically require a large number of participants, segmented by eligibility criteria such as age, health status, and medical history. Clinical studies, however, often involve fewer participants based on the characteristics of studies.
Moreover, any research that evaluates the aspects of a disease like the symptoms, risk factors, and pathophysiology, among others may be termed clinical research. However, clinical trials are those studies that assess the potential of a therapeutic drug/device in the management, control, and prevention of disease.
Screening trials test new ways for detecting diseases or health conditions. Diagnostic trials study or compare tests or procedures for diagnosing a particular disease or condition. Treatment trials test new treatments, new combinations of drugs, or new approaches to surgery or radiation therapy.
Community trials are an extension of field trials. In community trials the study group is the entire community, rather than individuals. Conceptually, the difference is whether or not the intervention is implemented separately for each individual.
