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.

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, ...

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.

One example is the Community Intervention Trial for Smoking Cessation (COMMIT), which involved 11 matched pairs of communities and randomized within these pairs to active community-level intervention versus comparison.

Community trials address the efficacy of preventive interventions applied at the group level (e.g., a social marketing campaign trial). Field trials address preventive interventions applied to individuals (e.g., a vaccine trial).

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.

Benefits of Community-Based Clinical Trials By including individuals from underserved populations, researchers can gather data on the safety and efficacy of interventions across different demographic groups, ensuring that treatments are effective for all patients.

Clinical trials target individuals whereas community trials target groups c. The study involves the recruitment of research participants who are randomized to receive one of two approved drugs.Communitybased clinical trials can help more patients access clinical trials than ever before and make recruitment easier. A Phase I trial takes several months to complete. About 70 percent of experimental drugs pass this initial phase of testing. Unsure whether your human subjects study meets the NIH definition of a clinical trial? There are three general types of epidemiologic experiments: community trials, field trials, and clinical trials. The concept-based nursing curriculum is designed for deep learning so that you develop higher-level clinical judgment.
