Is informed consent always required in research?


In the US, colon cancer is the third most common cancer and the second leading cause of cancer death. It usually affects men and women of all racial and ethnic groups alike, and is most common in people 50 years or older. Colon cancer is highly treatable when discovered early. It first develops as polyps (abnormal growths in the colon or rectum), but can become cancerous if not removed (medical news today, 2017).

The New England Journal of Medicine published a study regarding ethical issues and the overgeneralizations of research conventions, such as informed consent. A health system (name of health system not provided) has proposed to send birthday cards to patients when they turn 50 to promote colorectal screenings. The health system has three different reminder interventions and randomizes each patient to one intervention; however, since the word “randomization” is in play, should the IRB be involved in this study?

The three interventions implemented by this healthy system consists of 1) a whimsical card (“it’s your birthday, treat yourself to a colonoscopy”), 2) a birthday card with a prescheduled colonoscopy appointment, or 3) a usual message (control intervention). The health system is obviously conducting research by randomizing patients to different interventions with the hope of seeing a change in screening rates which can implemented in other healthy system; thus promoting justice. However, the IRB from this health system indicates that by not asking for permission, the patient’s rights not to participate is violated. Patients who turn 50 will be receiving a reminder from this health system anyways; therefore, the IRB insists on receiving consent from the patients.

The IRB is essential in protecting patient rights, but when the word “randomization” is used, it alarms the IRB to request consent. Asch et al., (2017), argues that the IRB is misdirected since the plan implemented by the health system does not involve more than minimal risk, the rights and welfare of subjects are not affected, and if patients were to consent, it would throw off the purpose of the research. Furthermore, the approaches are well-meaning, plausible, safe, and are consistent with clinical guidelines; thus, they are promoting the ethical value of beneficence. 

These regulations when conducting low-risk science studies, can make it difficult to do better science such as randomized studies which yield better results. Thus, it would leave scientist to rely on uncontrolled projects with pre-and post-evaluations which may not give accurate results of the general population. What is your opinion on the ethical issue? Should informed consent be required for low-risk science studies, such as the colorectal screening reminders?

  1. Informed consent should always be required; there should never be an exceptions to this rule, even if it is being considered a small randomized test. The blurring of the line may lead to further lines being blurred later in that study or another one. Well intentions aren’t always in the best interests of all parties involved. The Kennedy Krieger Institute’s “Lead-Based Paint Abatement and Repair and Maintenance Study”, the thievery of Henrietta Lacks’ cells or the Tuskegee syphilis study are all studies where informed consent was taken away from the parties involved. These are only a few of a multitude of studies that were conducted toward a vulnerable population where some profited while others suffered greatly. The removal of informed consent damns history to be repeated and vulnerable populations to once again undergo unnecessary hardships. Overall, patients should always have the right to stay autonomous over their body.
