However, evidence for recommending screening of dehydration is insufficient and its relation with frailty and mortality is unclear. We tested the hypothesis that postoperative HD is associated with frailty and increased mortality. Methods: We recruited 625 older (&gt;65 years) patients surgically treated for hip fracture and co-managed by an orthogeriatric team over one year in 2017. Pre- and postoperative HD (serum osmolarity &gt; 300 mmol\/L) was diagnosed. Frailty and associated mortality risk were assessed by the Multidimensional Prognostic Index (MPI). Results: The prevalence of preoperative HD was 20.4%. Compared with no-HD, MPI was similar in HD patients despite higher (p &lt; 0.05) prevalence of polypharmacy, arterial hypertension, diabetes, chronic kidney disease and heart failure. After surgery the incidence of HD decreased to 16.5%, but increased (p = 0.003) in the MPI high-risk subgroup. Postoperative HD was associated with more complications and was an independent determinant of adjusted hospital length of stay (LOS) and of 60- to 365-days mortality. Conclusions: Older frail patients with hip fracture are prone to developing postoperative HD, which independently predicts prolonged hospital LOS and mortality. Systematically screening older patients for frailty and dehydration is advisable to customize hydration management in high-risk individuals.<\/jats:p>","DOI":"10.3390\/nu14040820","type":"journal-article","created":{"date-parts":[[2022,2,16]],"date-time":"2022-02-16T21:36:24Z","timestamp":1645047384000},"page":"820","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Postoperative Dehydration Is Associated with Frailty and Decreased Survival in Older Patients with Hip Fracture"],"prefix":"10.3390","volume":"14","author":[{"given":"Michela","family":"Zanetti","sequence":"first","affiliation":[{"name":"Clinica Medica, Clinical Department of Medical, Surgical and Health Sciences, University Hospital of Trieste, Strada di Fiume 447, 34100 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paolo","family":"De Colle","sequence":"additional","affiliation":[{"name":"Geriatria, Department of Medicine, University Hospital of Trieste, Piazza dell\u2019Ospitale 1, 34100 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cinzia","family":"Omiciuolo","sequence":"additional","affiliation":[{"name":"Geriatria, Department of Medicine, University Hospital of Trieste, Piazza dell\u2019Ospitale 1, 34100 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiara","family":"Ratti","sequence":"additional","affiliation":[{"name":"Clinica Ortopedica, Clinical Department of Medical, Surgical and Health Sciences, University Hospital of Trieste, Strada di Fiume 447, 34100 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gianluca","family":"Gortan Cappellari","sequence":"additional","affiliation":[{"name":"Clinical Department of Medical, Surgical and Health Sciences, University Hospital of Trieste, Strada di Fiume 447, 34100 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rocco","family":"Barazzoni","sequence":"additional","affiliation":[{"name":"Clinica Medica, Clinical Department of Medical, Surgical and Health Sciences, University Hospital of Trieste, Strada di Fiume 447, 34100 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luigi","family":"Murena","sequence":"additional","affiliation":[{"name":"Clinica Ortopedica, Clinical Department of Medical, Surgical and Health Sciences, University Hospital of Trieste, Strada di Fiume 447, 34100 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8319-635X","authenticated-orcid":false,"given":"Gianfranco","family":"Sanson","sequence":"additional","affiliation":[{"name":"Clinical Department of Medical, Surgical and Health Sciences, University Hospital of Trieste, Strada di Fiume 447, 34100 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"690","DOI":"10.1302\/0301-620X.94B5.28933","article-title":"Causes and predictors of early re-admission after surgery for a fracture of the hip","volume":"94","author":"Khan","year":"2012","journal-title":"J.
