Abstract 16802: Intermittent Pneumatic Compression for Peripheral Artery Disease and End Stage Renal Disease to Improve Quality of Life and Functional Limitations
Background: Peripheral artery disease (PAD) is a prevalent condition affecting one in four patients with end stage renal disease (ESRD). Intermittent pneumatic compression (IPC) has proven benefits in PAD. We are conducting a trial testing the utility of IPC in the ESRD population by assessing the improvement in quality of life (QOL), functional limitation and walking performance from PAD-related symptoms. We aim to present our pilot results. Methods: Prospective single cohort study undergoing recruitment of outpatients at the hemodialysis (HD) unit of John H. Stroger Hospital. The calculated sample size is 78. PAD is confirmed by ankle-brachial index (ABI) and demographics obtained from interview and chart review. At baseline and post intervention, a Six-minute Walk Test (6MWT), Peripheral Artery Questionnaire (PAQ) and Walking Impairment Questionnaire (WIQ) are administered. The IPC device (Bio Arterial Plus) is used for intervention during HD. We present continuous variables as median (IQR) and categorical variables as percentage. Wilcoxon signed rank test was performed for comparison of results. Results: So far, 9 patients have completed intervention for the pilot study, 44% are men, the majority hispanic (66%), with age 48 (41-63) years. At baseline 66% of ABI were abnormal, all due to non-compressible PAD 1.46 (1.20-1.62). All patients have HTN, 44% diabetes, 33% hyperlipidemia and 33% heart failure. The median time of intervention is 70 (60-83) days. There was a significant difference in QOL measured by the WIQ (Fig.1), PAQ physical limitation (p=0.011), and PAQ social limitation (p=0.018). Although there was a trend towards benefit, no statistical difference was found on rest of objective and subjective measured parameters (p>0.05) Conclusions: Preliminary, IPC shows to improve many subsets of QOL in patients with ESRD and PAD. Given the small sample, improvement of walking distance remains elusive but with trends towards benefit.
