To examine the association related to LoS and HHF in patients with HF, a meta-analysis using a random-effects model was conducted (CRD42024570604). Our main analysis demonstrated a significantly increased LoS in patients with frailty versus those without frailty [n = 10; mean difference (MD): 3.67; 95% CI: 2.26\u20135.08, I2 = 93%, P &amp;lt; 0.01]. Likewise, patients with frailty had significantly increased odds of HHF [n = 17; odds ratio (OR): 1.76; 95% CI: 1.50\u20132.07, I2 = 81%, P &amp;lt; 0.01]. Risk of bias assessment of the included studies was overall fair, while Egger's test showed publication bias regarding studies that examined LoS (P = 0.02).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Patients with frailty have longer LoS and more frequent HHF, underscoring the need for early, targeted interventions to manage frailty that may be attributed primarily to ageing and comorbidity-related status.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/ehf2.15300","type":"journal-article","created":{"date-parts":[[2025,4,10]],"date-time":"2025-04-10T04:16:16Z","timestamp":1744258576000},"page":"2417-2426","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Length of Stay and Prior Heart Failure Admission in Frailty and Heart Failure: A Systematic Review and Meta-Analysis"],"prefix":"10.1093","volume":"12","author":[{"given":"Konstantinos","family":"Prokopidis","sequence":"first","affiliation":[{"name":"Department of Musculoskeletal and Ageing Science Institute of Life Course and Medical Sciences, University of Liverpool , Liverpool ,","place":["UK"]},{"name":"Liverpool Centre for Cardiovascular Science at University of Liverpool, Liverpool John Moores University and Liverpool Heart & Chest Hospital , Liverpool ,","place":["UK"]},{"name":"Liverpool Centre for Cardiovascular Science, University of Liverpool , Liverpool ,","place":["UK"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amy","family":"Nortcliffe","sequence":"additional","affiliation":[{"name":"Department of Musculoskeletal and Ageing Science Institute of Life Course and Medical Sciences, University of Liverpool , Liverpool ,","place":["UK"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chukwuma","family":"Okoye","sequence":"additional","affiliation":[{"name":"Aging Research Center, Department of Neurobiology, Care Sciences and Society (NVS), Karolinska Institutet, Stockholm University , Solna ,","place":["Sweden"]},{"name":"Department of Medicine and Surgery, University of Milan-Bicocca , Monza ,","place":["Italy"]},{"name":"Acute Geriatric Unit, IRCCS Foundation San Gerardo dei Tintori Monza , Monza ,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Massimo","family":"Venturelli","sequence":"additional","affiliation":[{"name":"Department of Neurosciences, Biomedicine and Movement Sciences, University of Verona , Verona ,","place":["Italy"]},{"name":"Department of Internal Medicine, University of Utah , Salt Lake City, Utah ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gregory Y.
