Longer and more frequent dialysis sessions have demonstrated clinical and survival benefits. Methods: A single-center observational study of the first one hundred patients on nocturnal every-other-day OL-HDF was conducted with the aim of reporting the experience with this treatment schedule and evaluating analytical and clinical outcomes as well as the patient and technique survival. Results: Nocturnal OL-HDF on alternate days was highly accepted, with no adverse symptoms, good clinical tolerance, and maintained active work in 62%. Kt, and the convective volume increased from 67.6 \u00b1 12 L to 105.4 \u00b1 11.7 L, and from 27.1 \u00b1 4.6 L to 48.1 \u00b1 6.4 L, respectively, from the baseline to 24 months. An improved calcium\u2013phosphate balance and blood pressure control were observed, as the use of phosphate binders and antihypertensive medications decreased from 76.7% to 3.3% and from 56.7% to 28.3%, respectively. Furthermore, 58.3% of patients required phosphate supplementation in the dialysis fluid to prevent intradialytic hypophosphatemia. Additionally, doses of iron and erythropoiesis-stimulating agents were reduced. The global patient survival was 94% at the end of the follow-up. It was higher in those on the transplant waiting list, with 98.1% survival compared to 84.6% in non-wait-listed patients at 24 months. The main reason for treatment discontinuation was kidney transplantation, accounting for 78.4% of the 88 withdrawals, while death was the leading cause of discontinuation in non-listed patients (41.6%). Conclusions: Nocturnal every-other-day OL-HDF is a well-tolerated dialysis regimen that offers significant clinical benefits, which may positively impact morbidity and mortality. Additionally, it allows patients to integrate the treatment into their social and occupational lives.<\/jats:p>","DOI":"10.3390\/jcm14010251","type":"journal-article","created":{"date-parts":[[2025,1,3]],"date-time":"2025-01-03T10:17:23Z","timestamp":1735899443000},"page":"251","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["An Observational Study of the First 100 Patients Undergoing Nocturnal Every-Other-Day Online Hemodiafiltration: Clinical Outcomes and Patient and Technique Survival"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1673-0353","authenticated-orcid":false,"given":"Francisco","family":"Maduell","sequence":"first","affiliation":[{"name":"Nephrology and Renal Transplantation, Hospital Cl\u00ednic de Barcelona, 08036 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0411-207X","authenticated-orcid":false,"given":"V\u00edctor Joaqu\u00edn","family":"Escudero-Saiz","sequence":"additional","affiliation":[{"name":"Nephrology and Renal Transplantation, Hospital Cl\u00ednic de Barcelona, 08036 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lida Maria","family":"Rodas","sequence":"additional","affiliation":[{"name":"Nephrology and Renal Transplantation, Hospital Cl\u00ednic de Barcelona, 08036 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2412-6911","authenticated-orcid":false,"given":"Elena","family":"Cuadrado","sequence":"additional","affiliation":[{"name":"Nephrology and Renal Transplantation, Hospital Cl\u00ednic de Barcelona, 08036 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"Morantes","sequence":"additional","affiliation":[{"name":"Nephrology and Renal Transplantation, Hospital Cl\u00ednic de Barcelona, 08036 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8023-2589","authenticated-orcid":false,"given":"Marta","family":"Arias-Guillen","sequence":"additional","affiliation":[{"name":"Nephrology and Renal Transplantation, Hospital Cl\u00ednic de Barcelona, 08036 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N\u00e9stor","family":"Fontser\u00e9","sequence":"additional","affiliation":[{"name":"Nephrology and Renal Transplantation, Hospital Cl\u00ednic de Barcelona, 08036 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5667-0650","authenticated-orcid":false,"given":"Nayra","family":"Rico","sequence":"additional","affiliation":[{"name":"Biochemistry and Molecular Genetics Department\u2014CDB, Hospital Cl\u00ednic de Barcelona, 08036 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4559-9083","authenticated-orcid":false,"given":"Jos\u00e9 Jes\u00fas","family":"Broseta","sequence":"additional","affiliation":[{"name":"Nephrology and Renal Transplantation, Hospital Cl\u00ednic de Barcelona, 08036 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"A8","DOI":"10.1053\/j.ajkd.2022.02.001","article-title":"US Renal Data System 2021 Annual Data Report: Epidemiology of Kidney Disease in the United States","volume":"79","author":"Johansen","year":"2022","journal-title":"Am.
