Background: A number of risk factors for C. difficile infection (CDI) are described in the literature, in particular an antibiotic therapy 4-6 weeks before disease, an age of >65 years, immunosuppression and living in a long-term care facility. Increasing incidence rates have been reported for Germany. CDI is the fourth most common nosocomial infection with 6.4%.
Aim: Due to the amendment of the Infection Protection Act of 01.05.2016, the proportion of all deaths that are C. difficile-associated deaths should be investigated to determine the extent to which the obligation to report is fulfilled in the case of a severe CDI. The epidemiological situation in Munich and Nuremberg should also be investigated and the characteristics of the deceased should be analyzed.
Material and methods: A review of all death certificates for the period from 1 January 2013 to 30 June 2016 was carried out according to defined inclusion criteria for clostridia infection. All data were anonymized, standardized and statistically evaluated.
Results: Almost every hundredth death is associated with C. difficile. Medical and outbreak reports are very poor and do not reflect the real situation. The age of the deceased and increased factors for the acquisition of a CDI correspond to the literature. The collected data from both cities show a good congruence.
Conclusion: For the first time, data from the health authorities can be submitted on the proportion of all deaths that are C. difficile-associated deaths, reporting behavior and patient characteristics in cases of severe CDI. This is a serious disease, especially for older people with regard to the existence of risk factors, and its frequency and effects are significantly underestimated.
