Thirst in heart failure: A scoping review.

Aim: The aim of this study was to summarise the overall picture of thirst-related research in patients with heart failure.

Design: We conducted a scoping review following the Arskey and O'Malley methodological framework along with the PAGER framework.

Methods: PubMed, CINAHL, Web of Science, Embase, The Cochrane Library, Jonna Briggs Institute, ProQuest Database, Google Scholar, PsycINFO, PQDT, CNKI, Wan Fang, VIP and CBM. Additionally, grey literature including grey databases (Opengrey, OpenDoar, Openaire and BASEL Bielefeld Academic Search Engine), conferences or articles (Scopus and Microsoft Academic), graduate theses databases (eTHOS, DART Europe, Worldcat and EBSCO Open Dissertations) and government information media (UK guidance and regulations, USA government websites, EU Bookshop and UN official publications) were searched. The databases were searched from inception to 18 August 2022 for Articles written in English and Chinese. Two researchers independently screened articles based on inclusion and exclusion criteria, and a third researcher adjudicated disagreements.

Results: We retrieved 825 articles, of which 26 were included. Three themes were summarised from these articles: (a) the incidence of thirst in patients with heart failure; (b) the thirst-related factors in patients with heart failure; and (c) the intervention measures of thirst in patients with heart failure.
