Abstract
Purpose
To present a new outcomes-based registry to collect data on outpatient endovascular
interventions, a relatively new site of service without adequate historical data to
assess best clinical practices. Quality data collection with subsequent outcomes
analysis, benchmarking, and direct feedback is necessary to achieve optimal care.
Materials and Methods
The Outpatient Endovascular and Interventional Society (OEIS) established the OEIS
National Registry in 2017 to collect data on safety, efficacy, and quality of care for
outpatient endovascular interventions. Since then, it has grown to include a peripheral
artery disease (PAD) module with plans to expand to include cardiac, venous, dialysis
access, and other procedures in future modules. As a Qualified Clinical Data Registry
approved by the Centers for Medicare and Medicaid Services, this application also
supports new quality measure development under the Quality Payment Program. All
physicians operating in an office-based laboratory or ambulatory surgery center can use
the Registry to analyze de-identified data and benchmark performance against national
averages. Major adverse events were defined as death, stroke, myocardial infarction,
acute onset of limb ischemia, index bypass graft or treated segment thrombosis, and/or
need for urgent/emergent vascular surgery.
Results
Since Registry inception in 2017, 251 participating physicians from 64 centers located
in 18 states have participated. The current database includes 18,134 peripheral
endovascular interventions performed in 12,403 PAD patients (mean age 72.3±10.2 years;
60.1% men) between January 2017 and January 2020. Cases were performed primarily in an
office-based laboratory (85.1%) or ambulatory surgery center setting (10.4%). Most
frequently observed procedure indications from 16,086 preprocedure form submissions
included claudication (59%), minor tissue loss (16%), rest pain (9%), acute limb
ischemia (5%), and maintenance of patency (3%). Planned diagnostic procedures made up
12.2% of cases entered, with the remainder indicated as interventional procedures
(87.6%). The hospital transfer rate was 0.62%, with 88 urgent/emergent transfers and 24
elective transfers. The overall complication rate for the Registry was 1.87% (n=338),
and the rate of major adverse events was 0.51% (n=92). Thirty-day mortality was 0.03%
(n=6).
Conclusion
This report describes the current structure, methodology, and preliminary results of
OEIS National Registry, an outcomes-based registry designed to collect quality
performance data with subsequent outcome analysis, benchmarking, and direct feedback to
aid clinicians in providing optimal care.
