Patient group-specific data sovereignty needs and acceptance of electronic health records

BACKGROUND AND AIMPeople in Germany are very sensitive about their health data. The electronic health record (ePA) also raises questions about the patient's need for data sovereignty and acceptance. The possibility of selectively withholding data stored in the ePA from physicians who continue to treat the patient (opt-out) and the patient's prior knowledge of the ePA could influence the need for data sovereignty and acceptance of the ePA. The aim of this explorative study is to investigate these influences for three patient groups: "acute patients," "diabetes type 2 patients," and "palliative patients," as differences are expected between these groups. MATERIALS AND METHODSFrom August to October 2019, a quantitative survey was conducted among 140 patients in the abovementioned groups. RESULTSOf the respondents, 76.0% supported the selective opt-out option and stated that this would increase their willingness to participate in the ePA. Specifically, 81.1% of acute care patients, 80.6% of palliative care patients, and 65.6% of type 2 diabetes patients made this statement. Differences between groups were not significant. A general prior knowledge of the ePA was related to a higher need for data sovereignty - 43.2% of those who had never heard of the ePA rollout would occasionally hide their health data from other physicians, compared with 54.5% who knew of the rollout. DISCUSSIONConsideration of the data sovereignty needs of patients in the further establishment of the ePA is recommended. The selective opt-out option can contribute to acceptance. Knowledge of the ePA should be expanded, especially in the doctor-patient discussion, to enable an informed decision.
