Abstract: An estimated 8 million individuals in America are affected by peripheral arterial disease (PAD), blockages of the leg arteries that can cause excruciating calf pain when walking. PAD can have a tremendous impact on patients' quality of life. It is also associated with high rates of heart attacks and premature death. While there are a number of treatments, there have been few previous studies that have prospectively examined treatment patterns for PAD or sought to systematically identify opportunities to improve care. Most importantly, there have been no rigorous studies examining the impact of the disease from patients' perspectives--their symptoms, function and quality of life--as a function of different patient characteristics and treatments. The PORTRAIT study (phase II) will systematically document the treatments and health status (symptom, function and quality of life) outcomes of 840 US patients over the course of one year from 9 centers to address these gaps in knowledge. It will illuminate whether disparities in treatment or health status outcomes exist as a function of patients' age, gender, race, or socioeconomic or psychological characteristics. As a direct deliverable, it will translate its findings--expected health status changes following PAD treatments over the course of one year--directly to patients through the development of patient education tools for patients with PAD that need to make a choice with regards to their treatment. As it is PCORI's mission to assist patients, clinicians, purchasers, and policy makers in making informed health decisions with regards to diseases like PAD, PORTRAIT will substantially elevate the field and identify critical gaps in the way PAD is currently managed, including potential disparities in care, so that the quality of care can be improved. PORTRAIT will also be a critical first step in designing efficient, effective disease management programs for PAD in the future that are based on more personalized and health care system-oriented approaches to increase the use of evidence-based guidelines. Finally, as patients have been closely involved in the design of this study (in phase I) and continue to be engaged as active advocates and experts of their disease throughout the current study, PORTRAIT will also empower patients and let them decide on what information and outcomes are most relevant for them while dealing with this burdensome condition of PAD.
