Both HCP provider procedure case volumes as well as HCO provider case volumes are determinants of outcomes.

Surgeon case volume, not institution case volume, is the primary determinant of in-hospital mortality after elective open abdominal aortic aneurysm repair. With AAA repair, mortality reduction was associated with annual institution volume (low <7, medium 7-30, and high >30) and annual surgeon volume (low ≤ 2, medium 3-9, and high >9). High surgeon volume conferred a greater mortality reduction than did high institution volume.
