Conclusion
This study reveals important data relating to the utilization and trends over time of preoperative anesthesia consultations within a large comprehensive population. Opportunities for discussion were found, including consultations provided for patients who did not proceed to surgery, and those healthier patients undergoing minimally to moderately invasive surgeries. These findings are consistent with the Choosing Wisely Canada section for anesthesia which suggests minimizing preoperative testing for asymptomatic patients (synonymous with ASA class I and II patients) undergoing minimally invasive surgeries. Future studies are needed to evaluate the safety of allocating preoperative anesthesiology consultations in particular groups, and the potential healthcare system efficiencies and economic benefits of these reductions.
