Abstract

Objective

The Western Aortic Collaborative (WAC) is a new, hybrid, multi-institutional academic model that seeks to perform aortic surgery research and education.

Methods

The WAC has three fundamental thoracic aortic surgery goals: (1) advancing surgical techniques, (2) furthering education and development of aortic surgeons, and (3) performing multi-institutional clinical research. The WAC utilizes a hybrid model of annual in-person meetings at the Western Thoracic Surgical Association (WTSA) combined with videoconferencing platforms that regularly connect surgeons dispersed throughout the Western region. The structure of WAC is intentionally horizontal. The goal is to promote cross-pollination of ideas, techniques, and experiences between surgeons at different institutions.

Results

For its research goals, the WAC first identified the principal areas of aortic surgery with the greatest knowledge gaps and which of those knowledge gaps could best be addressed by institutional practice differences within WAC. Using this natural experiment design, five high-priority research topics from the aortic root to the left subclavian artery were created. In order to perform this subspecialized, multi-institutional research, the WAC created a novel, cloud-based database that piggybacks on the Society for Thoracic Surgeon database. The combined database also preserves the ability to generate subspecialized variables and to link with each institution's medical record system for semi-automated functionality.

Conclusion

In its inaugural year, the WAC succeeded in its primary goals of utilizing remote technology platforms and the annual WTSA meeting to create a regional community of aortic surgeons with shared research and educational goals.
