Understanding how patients approach enrollment and where they encounter impediments may be useful for identifying strategies for enrollment outreach in individual communities or disease populations.
Take a look at our detailed infographic, filled with eye-opening statistics, to learn more about how to break down barriers found within the conceptual model of the accrural process:
The conceptual model of the accrual process describes three fundamental steps required for patients to enroll in clinical trials: awareness, opportunity, and decision-making. Patients can accept or refuse participation in a clinical trial only after being aware that the study is being conducted and having an opportunity to participate. Given the opportunity to participate, an individual may seek additional information regarding the potential harms or benefits of participation. The conceptual model serves as a framework to categorize barriers based on their effects on awareness, opportunity, and decisions about participation.
And while the barriers to minority enrollment in clinical trials are many, so are the number of approaches aimed at increasing enrollment. The process of deciding to enroll in a study is not necessarily linear, and for that reason specific approaches for overcoming barriers may in reality encompass more than one stage of decision-making.
