OBJECTIVES: There are few contemporary data regarding health-related quality of life (HRQOL) measures in patients with chronic limb-threatening ischemia (CLI). METHODS: The Best Endovascular versus Best Surgical Therapy in Patients with CLI (BEST-CLI) trial is an ongoing, National Institutes of Health-sponsored, multicenter, randomized, controlled trial comparing revascularization strategies in patients with CLI. BEST-CLI baseline HRQOL measures were evaluated for patient-specific variables that were associated with poor HRQOL and then compared with published outcomes. The HRQOL measures Vascular Quality of Life Questionnaire (VascQOL), European Quality of Life 5D (EQ-5D), and the Short Form 12 (SF-12) Index score, physical component score (PCS) and mental component score (MCS) were aggregated from preoperative questionnaires completed by trial patients at baseline visits. Multivariable linear regression models were fit to determine which baseline characteristics were associated with poor HRQOL. RESULTS: We randomized 1830 patients into BEST-CLI. The majority (94.9%, 95.8%, and 95.8%) completed the VascQOL, EQ-5D, and SF-12 instruments at baseline, respectively. In the VascQOL, female sex, smoking history, opioid use, and nonindependent ambulation predicted lower HRQOL scores. Overall, VascuQOL scores were similar to those of participants in the Bypass versus Angioplasty in Severe Ischemia of the Leg (mean, 3.07 ± 1.2 vs mean, 2.9 ± 1.1; P = .07). In EQ-5D, nonindependent ambulation predicted lower HRQOL scores. In the SF-12, female sex, opioid use, nonindependent ambulation, and a history of smoking predicted lower HRQOL scores. The mean SF-12 PCS for all patients in the study was 33.0 ± 8.5 and for the MCS was 46.4 ± 12.0), significantly lower than the national SF-12 scores for US population ages more than 60 years, which is a PCS of 46.5 ± 11.4 and an MCS of 52.9 ± 8.7. CONCLUSIONS: Patients with CLI entering the BEST-CLI trial have very low HRQOL scores, comparable with patients suffering from other chronic conditions characterized by physical limitations and chronic pain. A history of smoking, impaired ambulation, opioid use, and female sex predicted lower HRQOL in patients with CLI, using multiple HRQOL measurement tools.
