The statistics concerning the cause of death is one of the most important health statistics in the Federal Republic of Germany and allows important insights into the population’s state of health. Their data is based on death certificates which are issued as a part of post mortem examinations; these certificates include the circumstances, which lead to death, in an encoded form. If legal provisions would enable institutions for hospitalised geriatric care to make use of their deceased residents’ data, the manager of such an institution would be equipped with a tool for quality assurance: for instance, avoidable causes of death could be recognised and countered by different aspects of quality assurance. Such a use of the statistics concerning the cause of death is currently prevented by significant legal barriers; especially provisions regarding data protection, which in this case applies to post mortem, too. The following article presents the potential uses of the statistics concerning the cause of death in institutions of inpatient care and discusses as well as evaluates the legal options and limitations of such statistics.
