The randomized controlled clinical trial. Scientific and ethical bases

Area of Science:

• Medical research methodology
• Surgical innovation evaluation

Background:

• Randomized controlled trials (RCTs) are gaining acceptance for therapeutic evaluation.
• Implementation challenges persist, particularly for surgical interventions.
• Uncontrolled trials often acknowledge the need for controlled studies.

Purpose of the Study:

• To advocate for the widespread adoption and rigorous application of RCTs.
• To highlight the scientific, behavioral, and ethical justifications for RCTs.
• To establish RCTs as a prerequisite for publishing research on therapeutic innovations.

Main Methods:

• The abstract discusses the principles and practicalities of conducting RCTs.
• It emphasizes the design features that mitigate investigator bias.
• Ethical considerations, including informed consent and equal treatment allocation, are highlighted.

Main Results:

• Successful surgical RCTs prove their feasibility.
• RCTs are the most powerful tool for attributing outcomes solely to the intervention.
• Despite potential imperfections, RCTs are designed to minimize bias.

Conclusions:

• Scientific rigor, behavioral integrity, and ethical considerations strongly support RCTs.
• RCTs are the optimal method for investigating nearly all therapeutic innovations.
• RCTs should be a mandatory requirement for publication in medical research.
