Development of a multicenter peripheral arterial interventional database: the PVD-QI2

Area of Science:

• Vascular Surgery
• Cardiovascular Medicine
• Health Services Research

Background:

• Peripheral vascular intervention (PVI) procedures are increasingly common in the US.
• Peripheral arterial disease (PAD) management requires quality improvement initiatives.
• Understanding PVI effectiveness and appropriateness is crucial for patient outcomes.

Purpose of the Study:

• To establish a prospective, multicenter observational study (PVD-QI 2) for PVI quality improvement.
• To identify comorbid conditions and procedural variables impacting vascular intervention outcomes.
• To enhance the understanding of PVI effectiveness in improving PAD patient outcomes.

Main Methods:

• Prospective data collection from five centers on consecutive PVIs.
• Inclusion of patients with claudication and critical limb ischemia.
• Standardized data collection forms and definitions for demographics, history, comorbidities, treatments, and outcomes.
• Follow-up at 30 days, 6 months, and 1 year for vascular events, medication, lifestyle, walking scores, and mortality.
• Rigorous data validity checks including nurse review, database diagnostics, and site visits.

Main Results:

• Data collection is underway across five centers, focusing on diverse patient populations and PVI procedures.
• Comprehensive data on patient characteristics, interventions, and short-term outcomes are being gathered.
• Long-term patient follow-up is established to assess recurrent events, lifestyle changes, and mortality.

Conclusions:

• A quality-controlled PVI registry necessitates collaboration between clinicians and healthcare systems.
• A robust diagnostic and data quality assessment system is fundamental for registry success.
• The registry will yield critical insights into practice patterns influencing long-term quality outcomes for PAD patients.
