Background Recent evidence from randomized controlled trials has raised concerns about the long-term safety of paclitaxel-coated peripheral devices used for femoropopliteal artery revascularization. In response to a call for more real-world data on the safety of these devices, the SAFE-PAD study (Safety Assessment of Femoropopliteal Endovascular treatment with Paclitaxel-coated Devices) was designed with input from the Food and Drug Administration to provide a long-term, comprehensive evaluation of the mortality risk associated with paclitaxel-coated devices among Medicare beneficiaries. Methods and Results SAFE-PAD is an observational cohort study of fee-for-service Medicare beneficiaries that underwent femoropopliteal artery revascularization with either a drug-coated device or nondrug-coated device from 2015 through 2018. All patients age 66 years or older who underwent revascularization will be identified using a combination of International Classification of Diseases, Tenth Revision procedural codes, Current Procedural Terminology codes, and Healthcare Common Procedure Coding System C-codes. The safety end point of all-cause death will be updated semiannually and continued until the median duration of follow-up surpasses 5 years. Sub-group analyses will be conducted by device type, patient characteristics, and procedural setting. Registration: The SAFE-PAD study has been registered on URL: https://www.clinicaltrials.gov; Unique identifier: NCT04496544. Conclusions The SAFE-PAD study will evaluate the long-term safety of drug-coated devices compared with nondrug-coated devices for femoropopliteal artery revascularization among a broad, real-world population of patients with peripheral artery disease.
