However, delirium remains underdiagnosed by healthcare teams. Standardized assessments increase the chance of identifying the condition. The Ultra-Brief 2-item Screener (UB-2) is an effective tool for rapid screening for delirium. Considering the importance, the main objective of this study is to validate the UB-2 evaluate its performance as a screening tool in real-world public healthcare settings.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>This study included patients aged 65 years or older. Within the first 48\u00a0h after hospital admission, patients were assessed using the UB-2 by a trained evaluator to screen for delirium. At another time, a second evaluator applied the Confusion Assessment Method (CAM). The two tools were applied with a maximum interval of six hours between applications. Evaluators were blinded to the results of the other assessment tools.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>97 patients met the criteria for the study. Considering CAM-control as a reference, the UB-2 test had a sensitivity of 87.1% and specificity of 87.9%. The positive predictive value was 0.77 (95% CI: 0.60\u20130.90), and the negative predictive value was 0.94 (95% CI: 0.84\u20130.98). Furthermore, the positive likelihood ratio was 7.19 (95% CI: 3.70\u201313.95), whereas the negative likelihood ratio was 0.15 (95% CI: 0.06\u20130.37).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The UB-2 as a delirium screening tool appears to be feasible for clinical practice, and applicable in public healthcare setting of an middle-income country.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1186\/s12877-026-07711-4","type":"journal-article","created":{"date-parts":[[2026,6,9]],"date-time":"2026-06-09T11:05:52Z","timestamp":1781003152000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Clinical performance of an ultra-brief delirium screening tool in hospitalized older adults"],"prefix":"10.1186","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-2115-6378","authenticated-orcid":false,"given":"M M L","family":"Fochi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I M","family":"Suetugo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"V B","family":"Villar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G M","family":"Ara\u00fajo Filho","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,6,9]]},"reference":[{"issue":"12","key":"7711_CR1","doi-asserted-by":"publisher","first-page":"1161","DOI":"10.1001\/jama.2017.12067","volume":"318","author":"ES OH","year":"2017","unstructured":"OH ES, Fong TG.
