Abstract

Background: Compliance with guidelines for treating patients with peripheral artery disease (PAD) lags compliance for treating patients with coronary artery disease. We assessed the gap between guidelines and practice for patients with PAD who underwent lower extremity revascularization (LER) at our institution from 2007 to 2010.

Methods: Quality of care (QoC) was calculated by measuring provider performance on four indicators (antiplatelet therapy, dyslipidemia management, control of hypertension, and diabetes) derived from the ACCF/AHA PAD guidelines. The QoC score was calculated at the time of admission and at time of discharge for each patient, and reflects the proportion of indicated treatments received.

Results: Patients (n = 734, mean age 70±11, female 51%) were followed for a mean of 2.0±1.4 years (range 05.7) following LER. The indication for LER was claudication (24.8%), rest pain (16.7%), and tissue loss (58.4%). The percentage of patients with a perfect QoC score increased significantly during hospital admission (11% to 21%, p < 0.001). ignificant multivariate predictors of perfect QoC score included race/ethnicity, Charlson score, severity of LE ischemia, and observation period (admission, discharge). Multivariate analysis demonstrated that age>75 years, heart failure, chronic kidney disease, rest pain, and tissue loss-but not compliance with four guideline-based therapies-were associated with decreased freedom from the composite endpoint of major amputation, repeat revascularization, and death.

Conclusions: Although adherence to guidelines improved over time, we found a significant gap between guidelines and practice for this cohort of patients at increased risk for adverse cardiovascular events.
