Access Control Requirements for Processing Electronic Health Records
There is currently a strong focus worldwide on the potential of large-scale Electronic Health Record systems to cut costs and improve patient outcomes through increased e±ciency. A number of countries are developing nationwide EHR systems to aggregate services currently provided by isolated Electronic Medical Record databases. However, such aggregation introduces new risks for patient privacy and data security, both by linking previously-separate pieces of information about an individual, and by creating single access points to a wide range of personal data. It is thus essential that new access control policies and mechanisms are devised for federated Electronic Health Record systems, to ensure not only that sensitive patient data is accessible by authorized personnel only, but also that it is available when needed in life-critical situations. Here we review the traditional security models for access control, Discretionary Access Control, Mandatory Access Control and Role-Based Access Control, and use a case study to demonstrate that no single one of them is su±cient in a federated healthcare environment. We then show how the required level of data security can be achieved through a judicious combination of all three mechanisms.
Impact and interest:
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
