PURPOSE: Prior studies have demonstrated an overall decline in percutaneous renal artery angioplasty with and without stenting from 1988 to 2009. We evaluated the recent utilization trends in percutaneous renal arteriography (PTRA) among radiologists and non-radiologist providers from 2010 to 2018.
METHODS: Data from the 2010-2018 nationwide Medicare Part B fee-for-service database were used to tabulate case volumes for PTRA. Annual utilization rates per 10,000 Medicare beneficiaries were calculated and aggregated based on physician specialty: radiologists, cardiologists, vascular surgeons, general surgeons, or others.
RESULTS: From 2010 to 2018, the overall utilization rate of PTRA markedly declined (-72% change; from 15.5 to 4.3 cases per 10,000 Medicare beneficiaries). Proportionally, the cardiologist share of PTRA saw the greatest decline, falling from 74% market share in 2010 (11.4/15.5 cases) to only 36% market share in 2018 (1.6/4.3 cases). The market share of PTRA performed by radiologists grew from 12% market share in 2010 (1.9/15.5 cases) to 28% in 2018 (1.2/4.3 cases); despite this, the absolute number of PTRA performed by radiologists saw a smaller decline over this period (-34%; 1.9 to 1.2 cases).
CONCLUSION: The total utilization rates of PTRA in the Medicare population has continued to decline from 2010 to 2018, likely due to clinical trials suggesting limited efficacy of angioplasty and stenting in the treatment of renovascular hypertension and other factors such as declining reimbursement. The overall and per-specialty rates continue to decline, reflecting an overarching trend away from procedural management of renovascular hypertension.
