Quality of life and utility of patients with peripheral artery disease (PAD): a systematic review and meta-analysis.

Peripheral artery disease (PAD) patients experience low utility, especially those having undergone amputation. Utility is one of the quality weights of health status, converted from quality of life (QOL). This study aimed to systematically review published literature and analyze a pooled estimate of utility in PAD patients. The following databases were queried for articles published from inception up to August 30, 2022: PubMed, ScienceDirect, Scopus, ThaiJo, and the Thai thesis database. Four quality assessment tools were used, tailored to each study's design. A pooled utility was estimated by the random effect and reported using Rutherford and Fontaine classification systems due to their common use in practice. The protocol was registered with the International Prospective Registration of Systematic Reviews (CRD42023392775). Fourteen high-quality studies were included, pooling utility from 3,664 PAD patients. The pooled utility by the Rutherford categories was 0.67, with scores for categories 0, 1-3, 4, and 5 being 0.88, 0.65, 0.68, and 0.58, respectively. The pooled utility by the Fontaine stage was 0.68, with stages 1, 2, 3, and 4 scoring 0.88, 0.65, 0.67, and 0.58, respectively. PAD utility is comparable to that of other chronic diseases. The pooled utility could be a valuable parameter for cost-utility analysis in PAD management.
