Society for Vascular Surgery appropriate use criteria for management of intermittent claudication.

The Society for Vascular Surgery appropriate use criteria (AUC) for the management of intermittent claudication were created using the RAND appropriateness method, a validated and standardized method that combines the best available evidence from medical literature with expert opinion, using a modified Delphi process. These criteria serve as a framework on which individualized patient and clinician shared decision-making can grow. These criteria are not absolute. AUC should not be interpreted as a requirement to administer treatments rated as appropriate (benefit outweighs risk). Nor should AUC be interpreted as a prohibition of treatments rated as inappropriate (risk outweighs benefit). Clinical situations will occur in which moderating factors, not included in these AUC, will shift the appropriateness level of a treatment for an individual patient. Proper implementation of AUC requires a description of those moderating patient factors. For scenarios with an indeterminate rating, clinician judgement combined with the best available evidence should determine the treatment strategy. These scenarios require mechanisms to track the treatment decisions and outcomes. AUC should be revisited periodically to ensure that they remain relevant. The panelists rated 2280 unique scenarios for the treatment of intermittent claudication (IC) in the aortoiliac, common femoral, and femoropopliteal segments in the round 2 rating. Of these, only nine (0.4%) showed a disagreement using the interpercentile range adjusted for symmetry formula, indicating an exceptionally high degree of consensus among the panelists. Post hoc, the term "inappropriate" was replaced with the phrase "risk outweighs benefit." The term "appropriate" was also replaced with "benefit outweighs risk." The key principles for the management of IC reflected within these AUC are as follows. First, exercise therapy is the preferred initial management strategy for all patients with IC. Second, for patients who have not completed exercise therapy, invasive therapy might provide net a benefit for selected patients with IC who are nonsmokers, are taking optimal medical therapy, are considered to have a low physiologic and technical risk, and who are experiencing severe lifestyle limitations and/or a short walking distance. Third, considering the long-term durability of the currently available technology, invasive interventions for femoropopliteal disease should be reserved for patients with severe lifestyle limitations and a short walking distance. Fourth, in the common femoral segment, open common femoral endarterectomy will provide greater net benefit than endovascular intervention for the treatment of IC. Finally, in the infrapopliteal segment, invasive intervention for the treatment of IC is of unclear benefit and could be harmful.

Financial implications of coronavirus disease 2019 on a tertiary academic vascular surgery practice.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has had an unprecedented impact on the healthcare system in the United States. The redistribution of resources and suspension of elective procedures and other services has resulted in financial stress across all service lines. The financial effects on the practice of vascular surgery have not yet been quantified. We hypothesized that vascular surgery divisions have experienced losses affecting the hospital and professional sides that will not be recoupable without significant productivity increases. METHODS: Administrative claims data for clinical services performed by the vascular surgery division at a tertiary medical center for March and April 2019 and for March and April 2020 were analyzed. These claims were separated into two categories: hospital claims (inpatient and outpatient) and professional claims (professional reimbursement for all services provided). Medicare reimbursement methods were used to assign financial value: diagnosis-related group for inpatient services, ambulatory payment classification for outpatient services, and the Medicare physician fee schedule for professional reimbursement and work relative value units (wRVUs). Reimbursements and productivity (wRVUs) were compared between the two periods. A financial model was created to determine the increase in future productivity over baseline required to mitigate the losses incurred during the pandemic. RESULTS: A total of 11,317 vascular surgery claims were reviewed. Hospital reimbursement during the pandemic decreased from $4,982,114 to $2,649,521 (-47%) overall (inpatient, from $3,505,775 to $2,128,133 [-39%]; outpatient, from $1,476,339 to $521,388 [-65%]) and professional reimbursement decreased from $933,897 to $430,967 (-54%) compared with the same period in 2019. Professional productivity as measured by wRVUs sustained a similar decline from 10,478 wRVUs to 5386 wRVUs (-51%). Modeling sensitivity analyses demonstrated that if a vascular division were able to increase inpatient and outpatient revenue to greater than prepandemic levels by 10%, 5%, or 3%, it would take 9, 19, or 31 months, respectively, for the hospital to recover their pandemic-associated losses. Similarly, professional reimbursement recovery would require 11, 20, or 36 months with corresponding increases in productivity. CONCLUSIONS: The COVID-19 pandemic has had profound and lasting effects on the world in terms of lives lost and financial hardships. The financial effects on vascular surgery divisions has resulted in losses ranging from 39% to 65% compared with the prepandemic period in the previous year. Because the complete mitigation of losses is not feasible in the short term, alternative and novel strategies are needed to financially sustain the vascular division and hospital during a prolonged recovery period.
