Summary
Surgeon risk estimates for lung resection complications are unreliable. Experience alone does not ensure accuracy, highlighting the need for objective data and further research into improving these predictions.
Area of Science:
- Thoracic Surgery
- Surgical Education
- Patient Safety
Background:
- Surgeons often rely on experience for lung resection risk assessment, but factors influencing these estimates are unclear.
- Accurate risk prediction is crucial for optimizing patient outcomes in major lung resections.
Purpose of the Study:
- To evaluate the accuracy of surgeon risk estimates for lung resection complications.
- To determine if a calculated risk score improves estimate accuracy and agreement.
Main Methods:
- Clinical vignettes of lung resection patients (with/without complications) were used.
- Thoracic surgeons and trainees provided risk estimates before and after reviewing a calculated risk score.
Main Results:
- Surgeon risk estimates did not reliably differentiate between patients with and without complications.
- Predictive accuracy was only fair, though better for practicing surgeons than trainees.
- A calculated risk score improved estimate modification and agreement, particularly for trainees.
Conclusions:
- Surgeon risk estimates for lung resection complications are not accurate using vignette-based, matched-pair methodology.
- Estimates rely on limited objective data; trainees' estimates are more influenced by standard scores.
- Further prospective studies are needed to understand the etiology, accuracy, and utility of surgeon risk estimates.
