NCT03964844

Brief Summary

The microbiology department prospectively generates a data base of all episodes of Clostridium difficile infection (CDI) in the institution, the investigators will analyse the evolution of the episodes and the incidence per 10,000 days of stay of cases of diagnosed CDI in the Hematological wards and the rest of the hospital during the 2006-2018 period. The investigators will also compare the impact on haematological paediatric population. In order to analyse the clinical and epidemiological characteristics of CDI in this population, a case and control study will be conducted, reviewing the medical records of patients who have had an episode of diarrhoea caused by C. difficile in an hematological unit, which will be compared with non-hematological patients who have had an CDI episode These patients will be selected randomly from the Microbiology Department database. The sample size will be 400 patients, 200 per arm. The histories will be reviewed according to a pre-established clinical protocol including epidemiological, clinical, therapeutic and evolution variables. A prospective study in 2019-2020 will also be conducted. The investigators will include all patients diagnosed with an hematological/oncological disease or with any immunosuppressive condition, who have a positive detection of toxigenic Clostridium difficile. Patients will be followed for at least 2 months. For each patient a protocol data will be filled prospectively.

Study Population

Based on data from our center, for the retrospective part of the study, the total number of hematological patients with CDI corresponding to the study period is approximately 200 patients, all of them will be studied, the sample size for controls will be of 200 patients (ratio 1:1). For the prospective study, also based in data from our center, approximately 50 patients will be enrolled.

You may qualify if:

  • All patients diagnosed with a hematological disease who had a detection of toxigenic Clostridium difficile in the laboratory within the 2006-2018 period will be included in the study. Hematological patients with a negative CDI test in the same period will be included as controls.
  • All patients diagnosed with an hematological/oncological disease or with any immunosuppressive condition, who have a positive detection of toxigenic Clostridium difficile in 2019.

You may not qualify if:
