Primary outcome was first CDI recurrence, and secondary outcomes were readmissions during recurrent CDI episodes and 30-day all-cause mortality.</p><p><strong>Results: </strong>In total, there were 1435 patients with CDI included: 370 in the historical period (2014-2017), 537 in the educational-ASP period (2018-2020), and 528 in the CDI-specific clinical pathway period (2021-2023). First CDI recurrence rates significantly declined across periods in high-risk groups: immunocompromised patients, 29% in 2014-2017, 22% in 2018-2020, and 15% in 2021-2023 (p = 0.038); those with severe/fulminant initial CDI, from 38% to 34% to 24% (p = 0.027); and patients aged 65-79 years, from 29% to 31% to 13% (p = 0.003). Hospitalization during recurrent CDI episodes and mortality were significantly reduced in the CDI-specific clinical pathway period: readmissions, 11% (2014-2017), 13% (2018-2020), and 6% (2021-2023) (p = 0.017); mortality, 7%, 6%, and 4% (p = 0.023).</p><p><strong>Conclusions: </strong>The implementation of a structured, multifaceted clinical pathway specifically designed for CDI management had significant clinical benefits, including a reduction of recurrences in high-risk groups, readmissions, and mortality.</p><p><strong>Trial registration: </strong>ClinicalTrials.gov identifier NCT04801862.</p>","PeriodicalId":13592,"journal":{"name":"Infectious Diseases and Therapy","volume":" ","pages":"85-100"},"PeriodicalIF":5.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12783481/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145458388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
