Challenges to Randomized Trials in Adult and Congenital Cardiac and Thoracic Surgery

Area of Science:

• Surgical Research Methodology
• Clinical Trial Design
• Evidence-Based Surgery

Background:

• Randomized trials in surgery encounter unique obstacles distinct from medical trials.
• Challenges include blinding, surgeon learning curves, experience levels, and trial timing.
• Surgical culture, surgeon attitudes, and institutional support also impact trial conduct.

Purpose of the Study:

• To identify and discuss key challenges specific to conducting randomized trials in surgery.
• To propose potential solutions and strategies for overcoming these obstacles.
• To provide insights for improving the design and execution of surgical trials.

Main Methods:

• Review of existing literature and investigator experience in surgical trials.
• Discussion of intrinsic and extrinsic factors affecting surgical trial implementation.
• Identification of common issues in congenital, adult cardiac, and thoracic surgery trials.

Main Results:

• Significant challenges exist in blinding, surgeon variability, and trial design in surgical research.
• Surgical culture and lack of dedicated support systems hinder trial participation and success.
• Specific issues related to the timing and feasibility of comparative surgical trials were highlighted.

Conclusions:

• Addressing surgical trial challenges requires a multi-faceted approach involving methodological innovation and cultural shifts.
• Enhanced support from professional bodies and improved surgeon engagement are crucial.
• Implementing proposed solutions can strengthen the evidence base for surgical interventions.
