Multivariate analyses were performed to evaluate the association between blood eosinophilia (\u2265 500 cells\/\u00b5L) and length of hospital stay (\u2265 4 days).\nResults: Data from 225 children were analyzed; 15.1% had eosinophilia (exposed group), while the remaining 84.9% did not (non-exposed group). In the absence of pneumonia, the eosinophilia group was less likely to experience a prolonged hospital stay (RR = 0.6, P = 0.034). In this same group, eosinophils \u2265 500 cells\/\u00b5L reduced the likelihood of a hospital stay \u2265 4 days (adjusted OR 0.22, P = 0.005) in the multivariate analysis. Meanwhile, age \u2265 6 years (adjusted OR 4.12, P &lt; 0.001), moderate (adjusted OR 2.54, P = 0.016) and severe (adjusted OR 8.42, P = 0.003) Pulmonary Scores were predictors of prolonged hospital stay.\nConclusions: Blood eosinophilia \u2265 500 cells\/\u00b5L is associated with a shorter hospital stay. Additionally, children aged 6 years or older and those with moderate or severe exacerbations have a higher risk of prolonged hospitalization.<\/jats:p>","DOI":"10.15586\/aei.v54i5.1749","type":"journal-article","created":{"date-parts":[[2026,9,1]],"date-time":"2026-09-01T15:56:56Z","timestamp":1788278216000},"page":"58-65","source":"Crossref","is-referenced-by-count":0,"title":["Predictive usefulness of blood eosinophilia for hospital length of stay among children with asthma exacerbation"],"prefix":"10.15586","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-1712-9861","authenticated-orcid":false,"given":"Carlos Aar\u00f3n","family":"Lafarga-D\u00edaz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4915-1582","authenticated-orcid":false,"given":"Mart\u00edn","family":"Bedolla-Barajas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1492-1797","authenticated-orcid":false,"given":"Jaime","family":"Morales-Romero","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6170-5464","authenticated-orcid":false,"given":"Carlos","family":"Meza-L\u00f3pez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3504-9811","authenticated-orcid":false,"given":"Mar\u00eda Enriqueta","family":"Nu\u00f1ez-Nu\u00f1ez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4842-7578","authenticated-orcid":false,"given":"Ruth Yesica","family":"Ramos-Guti\u00e9rrez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5734-6534","authenticated-orcid":false,"given":"Beatriz","family":"Bayardo-Guti\u00e9rrez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7395-8760","authenticated-orcid":false,"given":"Christopher William","family":"Herrick-Ramos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"6228","published-online":{"date-parts":[[2026,9,1]]},"container-title":["Allergologia et Immunopathologia"],"original-title":[],"link":[{"URL":"https:\/\/www.all-imm.com\/index.php\/aei\/article\/download\/1749\/2542","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.all-imm.com\/index.php\/aei\/article\/download\/1749\/2543","content-type":"text\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.all-imm.com\/index.php\/aei\/article\/download\/1749\/2544","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.all-imm.com\/index.php\/aei\/article\/download\/1749\/2542","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,16]],"date-time":"2026-09-16T10:51:29Z","timestamp":1789555889000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.all-imm.com\/index.php\/aei\/article\/view\/1749"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,1]]},"references-count":0,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2026,9,1]]}},"URL":"https:\/\/doi.org\/10.15586\/aei.v54i5.1749","relation":{},"ISSN":["0301-0546"],"issn-type":[{"value":"0301-0546","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,9,1]]}}}
