An estimated 8 million individuals in America are affected by peripheral arterial disease (PAD). One of its extreme expressions is Critical Limb Ischemia (CLI). It is one of the most severe vascular conditions associated with devastating outcomes, including poorly healing wounds, extreme pain, and a high amputation risk. It is also one of the deadliest conditions, with 6-month and 5-year mortality rates estimated to be 20 and >50%, respectively. To date, however, there is a paucity of prospective clinical evidence about the variability in patients' presentations, their management or their outcomes. Accordingly, little progress has been made in adequately staging the disease and to risk-stratify treatment approaches to patients' individual characteristics. What is desperately needed to advance the care and management of patients with CLI is a focused research effort to set new standards for diagnosing, describing detailed patient-centered outcomes, and evaluating the variability in therapeutic approaches and their association with outcomes. The specific aims of SCOPE-CLI are to generate new evidence on the clinical characteristics, treatment patterns and outcomes of patients with critical limb ischemia (CLI); to describe treatment patterns and variability across practices to identify gaps in delivering quality care; and to perform a series of analyses to examine the associations of patient and treatment characteristics with outcomes. The central objective of SCOPE-CLI is to systematically quantify patients' CLI-specific health status and clinical outcomes and to perform subgroup analyses as a function of different PAD treatments and patient characteristics.
