An increase in healthcare utilization is an adverse outcome of frailty and disability.</p><p><strong>Objective: </strong>The aim of the present study was the prediction of six indicators of healthcare utilization by frailty and disability measures. The six indicators of healthcare utilization of interest were: use of informal care, number of visits to a general practitioner, hospital admission, receiving nursing care, receiving personal care, and contacts with (health)care professionals.</p><p><strong>Methods: </strong>We used a sample of 484 people that was randomly drawn from the municipality of Roosendaal (the Netherlands), a municipality with 78,000 inhabitants.

CD28null T cells were considerably higher (p<0.05) in the frail compared to the robust non-frail group, including in the CD8+ (47% vs 29%, p<0.05) and CD4+ (4% vs 1%, p<0.05) fractions. CD28null T cell percentage was also higher (p<0.05) in those with moderate CI compared to mild CI and normal function.</p><p><strong>Conclusion: </strong>CD8+CD28null T cells are considerably elevated in frailty and with cognitive impairment and may serve as a useful target for intervention. Currently, the utility of CD31+ T cells as an ageing biomarker may be confined to healthy ageing cohorts.</p>","PeriodicalId":51629,"journal":{"name":"Journal of Frailty & Aging","volume":"13 3","pages":"203-212"},"PeriodicalIF":3.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141857116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
