It is understandable to attempt to determine the factors that can predict the severity of the course of the infection and identify patients at risk of death. This study aimed to analyze the factors affecting the incidence and mortality of CDI in inpatient treatment at the University Clinical Hospital in Wroc\u0142aw in 2016\u20132018.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>Statistical analysis of data obtained from patients\u2019 medical records was performed. Only patients with symptoms of infection and infection confirmed by laboratory tests were enrolled in the study. When analyzing the number of deaths, only adult patients who died in hospital wards were included. The quantitative data including laboratory tests, used antibiotics and Nutritional Risk Screening (NRS) were assessed. Also, the qualitative data such as sex, year of hospitalization, occurrence of diarrhoea on admission to the hospital, presence of additional diseases, as wee ad the use of antibacterial drugs or proton pump blockers and ranitidine during hospitalization were analyzed.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>A total of 319 adult CDI patients (178 women and 141 men) were enrolled of which 80 people died (50 women and 30 men). The mean age of the patients was 72.08\u2009\u00b1\u200916.74 years. Over the entire period studied, the morbidity was 174 cases per 100,000 hospitalizations while mortality was 25.08%. The group of deceased patients was characterized by: older age (by 9.24 years), longer duration of hospitalization (by 10 days), reduced albumin levels (Rho = -0.235, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), higher urea levels, use of more antibiotics, higher risk of malnutrition in NRS (Rho\u2009=\u20090.219, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), higher incidence of sepsis, heart failure, stroke, hypothyroidism. Pneumonia was diagnosed twice as often. It was also shown that deceased patients were significantly more likely to take penicillin and fluoroquinolones.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>In this study, the morbidity was lower, but mortality was higher compared to similar hospitals in Poland. CDI patients were characterized by older age, multimorbidity, extended hospitalization, and the use of broad-spectrum antibiotics. Risk factors for death included advanced age, prolonged hospital stays, lower albumin, higher urea, malnutrition, and comorbidities like heart failure, stroke, pneumonia, sepsis, and hypothyroidism. Increased antibiotic use, particularly penicillin and fluoroquinolones, was associated with a higher mortality risk.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12879-024-09495-7","type":"journal-article","created":{"date-parts":[[2024,6,23]],"date-time":"2024-06-23T18:02:13Z","timestamp":1719165733000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Mortality in clostridioides difficile infection among patients hospitalized at the university clinical hospital in Wroclaw, Poland \u2013 a 3-year observational study"],"prefix":"10.1186","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5472-1485","authenticated-orcid":false,"given":"Jaros\u0142aw","family":"Drobnik","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9216-451X","authenticated-orcid":false,"given":"Piotr","family":"Pobrotyn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7397-6133","authenticated-orcid":false,"given":"M\u00e1ria","family":"Belovi\u010dov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3624-3691","authenticated-orcid":false,"given":"Katarzyna","family":"Madziarska","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3951-205X","authenticated-orcid":false,"given":"Ma\u0142gorzata","family":"Trocha","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3652-6309","authenticated-orcid":false,"given":"Mateusz","family":"Baran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,6,23]]},"reference":[{"key":"9495_CR1","doi-asserted-by":"publisher","first-page":"1211","DOI":"10.1007\/s10096-019-03539-6","volume":"38","author":"J Czepiel","year":"2019","unstructured":"Czepiel J, Dr\u00f3\u017cd\u017c M, Pituch H, Kuijper EJ, Perucki W, Mielimonka A, et al.
