Abstract
According to the General Data Protection Regulation (GDPR 05/2018), anonymized data sets with a sufficiently high data density are classified as traceable and require a declaration of consent if they are evaluated centrally for research or quality control purposes. Quality assurance and further increases in the quality of care are, however, only possible with a nearly complete survey of seriously injured persons in the sense of health services research. The more than 600 German clinics that take part in the TraumaRegistry DGU® try to obtain the declarations of consent from this special patient population. The study clinic evaluated the rate of consent and the reasons for rejection or failure to obtain consent over a 12-month period. While using a resource-intensive workflow especially for patient education and obtaining the consent, a patient consent rate of 64.5% and an error rate of 35.5% were recorded. Of the 276 potential TraumaRegistry DGU® data records 98 could not be entered and were therefore neither available for quality control nor for multiple trauma research. In order to guarantee the quality control and the further improvement of the quality of care, an approximate total recording of the patient population is necessary; however, this cannot be achieved by requiring a declaration of consent. We therefore advocate creating the possibility of collecting the TraumaRegistry data set without consent, as this ultimately represents a standard data set, comparable to the Hospital Remuneration Act (§21-KHEntgG) data set but pseudonymised.
