A forensic analysis of spin-off and downstream revenue in an academic vascular surgery practice: Unveiling the "vascular X-factor" in a tertiary health care system.

Background: Owing to the high level of patient and operative complexity, vascular surgery represents a major driver for elevating case mix index within health care institutions. Although several specialty services are recruited in the care of these patients, it has been difficult to quantify the financial impact of these vascular patient across the health care enterprise. This study aims to quantify all revenues attributable to the introduction of vascular surgery patients within a tertiary health care system.
