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.
Methods: Billing data from 2017 to 2020 for all new vascular surgery patients entering a tertiary health care system were captured, and segregated by encounter type--inpatient versus outpatient. Within these major categories, vascular revenue streams were analyzed according to procedural pathology types, such as aneurysm, peripheral vascular disease, cerebrovascular, and venous. Subsequent revenues for nonvascular services were also captured for both inpatient and outpatient encounters that were tied to the initial vascular surgical encounter. Revenues attributable to vascular patients were analyzed and followed with respect to other hospital service lines.
Results: A total of 1115 new patients were introduced to the health care system for the first time by vascular surgery. These new patients generated more than $26 million in gross revenue and more than $10 million in contribution margin to the hospital during this time interval in aggregate. From a procedural standpoint, aortic surgery generated more than $7.4 million in revenue and $2.9 million in health system contribution margin. Peripheral vascular disease contributed $7.3 million and $2.6 million in revenue and contribution margins, respectively. Aortic surgery cases generated the highest margin per encounter encompassing the total sum of contributions. Subtracting all revenue attributable to vascular billing (spin-off), new patients brought in by vascular generated $9.6 million in revenue and $4.3 million in contribution margin from other service lines. Vascular access procedures produced the greatest spin-off margin per encounter at $10,985, and ancillary inpatient/outpatient generated the greatest number of spin-off encounters (n = 597) and revenue ($8,181,708).
Conclusions: Patients introduced by a tertiary care vascular surgery program produce a significant revenue/margin for the parent health care system. When considering the fiscal health of a vascular program within a tertiary health care system, spin-off and downstream revenue should be considered in terms of overall value.
