Randomized controlled trials (RCTs) can answer only 40% of surgical treatment questions. Patient preference, rare conditions, and lack of clinical equipoise are key barriers to conducting RCTs in surgery.

Area of Science:

  • Surgical Research
  • Clinical Trials
  • Evidence-Based Medicine

Background:

  • Evaluating surgical treatments presents unique challenges for clinical research.
  • Randomized controlled trials (RCTs) are the gold standard for treatment evaluation but may not always be feasible in surgery.

Purpose of the Study:

  • To determine the proportion of surgical treatment evaluation questions answerable by RCTs.
  • To identify barriers that prevent the initiation of RCTs for surgical procedures.

Main Methods:

  • A computerized literature search identified treatment evaluation questions for surgical procedures.
  • Defined criteria were used to assess the feasibility of RCTs and identify precluding problems.
  • Interobserver and intraobserver reliability of these criteria were evaluated.

Main Results:

  • Only 38.8% of surgical treatment questions could be addressed by RCTs in an ideal setting.
  • Patient preference was the most common barrier (40%), followed by uncommon conditions (24.2%) and lack of clinical equipoise (10%).
  • Methodological issues and surgeon preference were infrequent barriers.

Conclusions:

  • RCTs are suitable for evaluating less than half of surgical treatment questions.
  • Patient preferences, rare conditions, and lack of equipoise significantly limit the application of RCTs in surgical research.
