Clinical Record Systems in Oncology. Experiences and Developments on Cancer Registers in Eastern Germany

Abstract

Healthcare information systems have to guarantee quality and efficiency of the medical maintenance. The basis of such information systems is an good medical and caring documentation. The labour-shared cooperative care for cancer patients as ``Shared Care{''} requires a complete, distributed cancer documentation, summarized in clinical cancer registers. The information of those registers are also a basis for a population-related epidemiological registry. Cancer registers must meet all demands in data protection. This paper deals with the security architecture of distributed information systems. Organizational as well as technical problems are discussed. Essential attention is paid to security modelling and access rights. The actual structure of the regional Clinical Cancer Register Magdeburg/Saxony-Anhalt and the existing as well as the planned register security mechanisms are presented.
