What this trial studies

This study evaluates the effectiveness of a multi-component behavioral intervention aimed at anesthesiologists and surgeons to reduce the ordering of low-value preoperative tests, such as electrocardiograms and chest X-rays, in patients undergoing low-risk surgeries. The intervention is based on the Choosing Wisely De-Implementation Framework and seeks to change behaviors and decisions among healthcare providers in Ontario, Canada. The study will assess the overall rate of these low-value tests, along with economic and process evaluations, across 22 hospitals. By addressing low-value care, the study aims to improve patient outcomes and healthcare efficiency.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who are scheduled for low-risk surgeries such as endoscopy, ophthalmologic surgery, knee arthroscopy, or hernia repair.

Not a fit: Patients undergoing emergency elective procedures or those requiring chest X-rays and electrocardiograms for urgent reasons may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to a significant reduction in unnecessary preoperative testing, improving patient safety and reducing healthcare costs.

How similar studies have performed: Other studies have shown success in reducing low-value care through behavioral interventions, making this approach promising yet still innovative in its application.
