Serum lactate reflects tissue hypoperfusion, whereas hypoalbuminemia indicates systemic inflammation and poor nutritional status. The aim of this study is to evaluate the ability of the lactate-to-albumin ratio (LAR) to predict ICU admission in patients with DFI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      This retrospective study was conducted in the emergency department of a tertiary care center between 01.01.2022 and 01.01.2025. Adult patients (\u226518 years) with confirmed DFI were included. DFI diagnosis was established\n                      <jats:bold>in accordance with IWGDF\/IDSA 2023 criteria.<\/jats:bold>\n                      <jats:sup>\n                        <jats:xref ref-type=\"bibr\">1<\/jats:xref>\n                      <\/jats:sup>\n                      Patients with chronic liver failure, nephrotic syndrome, pregnancy, or incomplete records were excluded. LAR was calculated as lactate (mmol\/L) divided by albumin (g\/dL).

ICU patients had higher lactate (2.5 vs 1.8\u2005mmol\/L, P\u2009&lt;\u2009.001), lower albumin (3.2 vs 3.4\u2005g\/dL, P\u2009&lt;\u2009.001), and higher LAR (0.8 vs 0.5, P\u2009&lt;\u2009.001). LAR demonstrated the best discrimination for ICU admission (AUC, 0.717; 95% CI, 0.658-0.777), outperforming albumin (AUC, 0.626; P\u2009=\u2009.009) and similar to lactate (AUC, 0.702; P\u2009=\u2009.134). A cut-off of \u22650.73 yielded 57.1% sensitivity and 78.2% specificity. LAR (OR, 1.36; 95% CI, 1.16-1.58; P\u2009&lt;\u2009.001), older age, lower mean arterial pressure, and lower ankle\u2013brachial index were independent predictors of ICU admission.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The lactate-to-albumin ratio is a simple, cost-effective biomarker that independently predicts ICU admission in DFI patients and may aid early risk stratification. Although LAR did not demonstrate statistically superior discrimination over lactate alone, it integrates systemic metabolic stress with the host's inflammatory and nutritional reserve, offering a composite measure of physiological vulnerability in this high-risk population.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/15347346261460272","type":"journal-article","created":{"date-parts":[[2026,6,11]],"date-time":"2026-06-11T09:15:08Z","timestamp":1781169308000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Lactate-to-Albumin Ratio for Predicting Intensive Care Unit Admission in Patients with Diabetic Foot Infection"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9248-7527","authenticated-orcid":false,"given":"Kaan","family":"Yusufoglu","sequence":"first","affiliation":[{"name":"Haydarpasa Numune Training and Research Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Omer","family":"Yonga","sequence":"additional","affiliation":[{"name":"Yeditepe University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,6,11]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1093\/cid\/ciad527"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.3892\/etm.2023.12070"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1186\/cc3818"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.5505\/vtd.2019.24993"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2016.0287"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.3389\/fmed.2020.550182"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jemermed.2025.08.031"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13054-021-03693-4"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/awab040"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12890-025-03698-7"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-0043-1761471"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12879-025-10601-6"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1017\/dmp.2022.299"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcot.2021.01.017"},{"key":"e_1_3_3_16_2","doi-asserted-by":"publisher","DOI":"10.3389\/fpubh.2023.1181880"},{"issue":"1","key":"e_1_3_3_17_2","first-page":"86","article-title":"Epidemiyolojide G\u00f6zlemsel \u00c7al\u0131\u015fmalar\u0131n Raporlanmas\u0131: STROBE Kriterlerinin T\u00fcrk\u00e7e Uyarlamas\u0131","volume":"5","author":"Babao\u011flu AB","year":"2021","unstructured":"Babao\u011flu AB, Tekindal M, B\u00fcy\u00fckuysal M\u00c7, et al.
