We evaluated the classification impact of binary postoperative intensive care unit (ICU) admission and the additional information retained by actual ICU duration after colorectal cancer surgery. Methods: This retrospective single-center cohort included 241 patients undergoing colorectal cancer resection between 2020 and 2026. Comprehensive TO required no major postoperative complication, reoperation, 30-day mortality, or postoperative ICU admission, together with microscopically margin-negative (R0) resection of the colorectal primary and postoperative length of stay \u226414 days. Core TO omitted ICU admission and length of stay and was used as an analytical comparator rather than as a newly validated TO definition. Patient-level reclassification was the primary outcome. ICU duration was evaluated continuously in the principal concurrent-association analysis; the 0-, 1-, 2-, and \u22653-day categories were exploratory. Results: Comprehensive and core TO were achieved in 27 (11.2%) and 169 (70.1%) patients, respectively, resulting in reclassification of 142 patients (58.9%; exact McNemar p &lt; 0.001). ICU admission alone accounted for reclassification in 118 patients (49.0% of the cohort). Each additional ICU day showed a concurrent association with higher odds of core TO failure (adjusted odds ratio (OR), 1.43; 95% confidence interval (CI), 1.25\u20131.63) and major postoperative complications (adjusted OR, 1.63; 95% CI, 1.40\u20131.91; both p &lt; 0.001). Categorical estimates for 1- and 2-day stays were imprecise and did not establish equivalence with no ICU admission. Duration-sensitive representations showed better internal model fit, discrimination, and probabilistic performance than binary ICU admission. Conclusions: In this center with frequent postoperative ICU utilization, binary ICU admission dominated comprehensive TO classification. ICU duration retained additional clinical information, but the findings do not establish the intrinsic invalidity of the ICU component, equivalence of short stays with no ICU admission, or a universal duration cutoff. Multicenter external validation across different ICU policies is required.<\/jats:p>","DOI":"10.3390\/jcm15176809","type":"journal-article","created":{"date-parts":[[2026,9,2]],"date-time":"2026-09-02T10:02:52Z","timestamp":1788343372000},"page":"6809","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Beyond Binary ICU Admission: Duration-Sensitive Evaluation and Patient-Level Reclassification of Textbook Outcome After Colorectal Cancer Surgery"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2432-7334","authenticated-orcid":false,"given":"Adem","family":"Ozcan","sequence":"first","affiliation":[{"name":"Department of Surgical Oncology, Ankara Bilkent City Hospital, Ankara 06800, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5761-4052","authenticated-orcid":false,"given":"Gizem","family":"Gunes","sequence":"additional","affiliation":[{"name":"Department of Surgical Oncology, Ankara Bilkent City Hospital, Ankara 06800, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"validation","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4259-3217","authenticated-orcid":false,"given":"Ali","family":"Bal","sequence":"additional","affiliation":[{"name":"Department of Surgical Oncology, Ankara Bilkent City Hospital, Ankara 06800, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"}]},{"given":"Abdulkadir","family":"Unsal","sequence":"additional","affiliation":[{"name":"Department of Surgical Oncology, Ankara Bilkent City Hospital, Ankara 06800, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"156","DOI":"10.1016\/j.ejso.2012.10.007","article-title":"Focusing on desired outcomes of care after colon cancer resections: Hospital variations in \u2018textbook outcome\u2019","volume":"39","author":"Kolfschoten","year":"2013","journal-title":"Eur.
