The objective of this study was to assess mortality among the patients of the Hospital for Infectious Diseases in Warsaw related to\n                    <jats:italic>C.difficile<\/jats:italic>\n                    infection. Analysis was conducted of 1638 records reporting the medical histories of patients hospitalized for the first time due to\n                    <jats:italic>Clostridioides difficile infection<\/jats:italic>\n                    (CDI) in the Hospital for Infectious Diseases in Warsaw from 2010 to 2017. The inclusion criteria were any (principal or secondary) discharge diagnosis code for CDI according to ICD-10 and being an adult (\u2265\u200918\u00a0years). 108 out of 1638 (7%) of the patients died. The median age in this group was 83\u00a0years. The largest number of deaths (90%) occurred in the group of patients aged 65\u00a0years or older and 81\u201390\u00a0years old (53% of all the deaths). In the multivariate logistic regression model relevant only to the age groups, not to sepsis\u2014age over 80 and over 90 were independent predictors of death, increasing the risk of death by 3.4 and 1.8 times, respectively. The result of the receiver operating curve (ROC) analysis determined the age of 77\u00a0years as the threshold value, indicating the increased risk of death (AUC 0.727, standard error 0.025, 95% CI 0.678\u20130.776,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.0001). In addition, other quantitative variables, namely CRP, creatinine and leucocytes were studied and turned out to be independent death predictors as well. The diagnosis of sepsis increased the risk of death fourfold (OR\u2009=\u20094.042; 95% Cl 2.4\u20136.7;\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001). Increased inflammatory parameters, namely CRP and white blood cell count, advanced age, particularly over the age of 80, as well as a diagnosis of sepsis are independent risk factors for death and could be used as predictive markers of poor outcome in CDI.\n                  <\/jats:p>","DOI":"10.1038\/s41598-020-71466-0","type":"journal-article","created":{"date-parts":[[2020,9,7]],"date-time":"2020-09-07T06:02:52Z","timestamp":1599458572000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Advanced age and increased CRP concentration are independent risk factors associated with Clostridioides difficile infection mortality"],"prefix":"10.1038","volume":"10","author":[{"given":"Agnieszka","family":"Bednarska","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominik","family":"Bursa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Regina","family":"Podlasin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcin","family":"Paciorek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6367-5633","authenticated-orcid":false,"given":"Agata","family":"Skrzat-Klapaczy\u0144ska","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dawid","family":"Porowski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joanna","family":"Raczy\u0144ska","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joanna","family":"Pu\u0142a","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominika","family":"Krogulec","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Micha\u0142","family":"Makowiecki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrzej","family":"Horban","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,9,7]]},"reference":[{"key":"71466_CR1","volume-title":"Harrison's Infectious Diseases","author":"DL Kasper","year":"2017","unstructured":"Kasper, D.
