Hischke S, Rieß HC, Bublitz MK, et al. - Researchers performed a systematic review to recognize evidence-based quality indicators for invasive revascularisation of symptomatic peripheral arterial occlusive disease (PAOD). They selected one systematic review and one consensus statement focusing on quality indicators for inclusion in the review. In the literature, there was a lack of published evidence-based quality indicators concerning invasive treatment for PAOD. They identified a total of three process quality indicators from the sources that matched the search criteria: one on pharmacological intervention, another on smoking cessation, and a third on surveillance of lower extremity vein bypass grafts. Prior guidelines did not incorporate an additional 31 indicators from the databases of professional societies and organizations.
