Definition. Community intervention trials are research studies designed to evaluate the effects of public health interventions on a community-wide basis, rather than on individuals.
Intervention groups, sometimes referred to as treatment groups, receive some form of intervention, such as a new reading program, designed to result in some change in behavior. Control or comparison groups do not receive the intervention.
In summary, the primary distinction lies in the focus on human subjects and the testing of interventions in clinical trial research, whereas non-clinical trial research encompasses a broader spectrum of studies that may not involve direct interventions on human participants.
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.
(kun-TROLD KLIH-nih-kul TRY-ul) A clinical study that includes a comparison (control) group. The comparison group receives a placebo, another treatment, or no treatment at all.
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.
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, ...
As mentioned in our publication Types of Clinical Trial Design, one of the designs is based, on the inclusion or not, of a control group to compare the effects of the investigational treatment. Trials that do not include it are called uncontrolled trials and those that do are called controlled trials.
But the most important benefit of community-based clinical trials is that patients have more options for their healthcare. By embracing community-based clinical trials, small sites and sponsors can give patients, including underrepresented patients, treatment options they've never experienced before.
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.
