conversion rate
The percentage of minimally invasive procedures that require conversion to open surgery due to complications or technical difficulties.
Full Definition
A key quality metric in minimally invasive surgery representing the frequency at which laparoscopic or robotic procedures must be converted to open surgical approaches. Conversion may be necessary due to bleeding, anatomical complexity, equipment failure, or patient safety concerns. Conversion rates are procedure-specific benchmarks used for quality improvement, surgeon credentialing, and patient counseling regarding surgical risks.
Usage
Usage note: Always specify the procedure type when citing conversion rates.
