This retrospective cohort study included 344 patients with moderate to severe diabetic foot infections. Patients were categorized into three groups based on presenting estimated eGFR: eGFR \u226560 (eGFR &gt;60\u2009mL\/min), eGFR 30\u201360 (eGFR 30\u201360\u2009mL\/min) and eGFR &lt;30 (eGFR &lt;30\u2009mL\/min). Outcomes assessed included wound healing, time to heal, re\u2010infection, amputation, mortality and re\u2010hospitalization for infection. Compared with patients with eGFR &lt;30, patients with eGFR \u226560 had significantly lower rates of retinopathy, peripheral arterial disease and use of beta blockers or calcium channel blockers. Glycated haemoglobin levels were inversely related to eGFR, decreasing as eGFR severity increased. Haemoglobin levels were significantly lower, and inflammatory markers (ESR and CRP) were significantly higher in patients with eGFR &lt;30. There were no significant differences among eGFR groups in rates of wound healing, time to heal, re\u2010infection or amputation. However, mortality increased with decreasing eGFR (1.9% in eGFR \u226560 vs. 3.2% in eGFR 30\u201360 vs. 8.1% in eGFR &lt;30; <jats:italic>p<\/jats:italic>\u2009=\u20090.04). Similarly, re\u2010hospitalization for infection at a different site also increased with decreasing eGFR (20.5% in eGFR \u226560 vs. 28.1% in eGFR 30\u201360 vs. 48.4% in eGFR &lt;30; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01). In diabetic foot infections, presenting eGFR severity did not affect rates of wound healing, time to heal, re\u2010infection or amputation. However, decreasing eGFR was associated with increased mortality and re\u2010hospitalization for infection at a different site. In this study, presenting eGFR was not a predictive value for wound healing or time until healing, however was associated with rehospitalization and overall mortality this diabetic foot population.<\/jats:p>","DOI":"10.1111\/iwj.70122","type":"journal-article","created":{"date-parts":[[2025,5,5]],"date-time":"2025-05-05T01:35:07Z","timestamp":1746408907000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The dialysis foot\u2010 the impact of presenting estimated glomerular filtration rate on clinical outcomes in patients hospitalized with diabetic foot infections"],"prefix":"10.1111","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5311-6283","authenticated-orcid":false,"given":"Arthur","family":"Tarricone","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery The University of Texas Health Science Center  San Antonio Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tyler L.","family":"Coye","sequence":"additional","affiliation":[{"name":"Michael E DeBakey Department of Surgery Baylor College of Medicine  Houston Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allen","family":"Gee","sequence":"additional","affiliation":[{"name":"Nova Southeastern University Dr. Kiran C.
