Informed consent and the security of the electronic health record (EHR): some policy considerations.

Various codes of ethics, and in particular the IMIA Code of Ethics for Health Information Professionals (HIPs), stipulate that the subject of an electronic health record (EHR) has a series of security rights with respect to her/his EHR, and that to some degree these rights center in the notion of informed consent. This paper examines the ethical basis of this position, outlines its implications for professionals, institutions and society in general, and identifies its limits. Further issues that will be discussed include who carries the responsibility for informed consent, what nature it should take, whether web-based EHRs present ethically unique problems, and related security implications.

A cross-platform model for secure Electronic Health Record communication.

During the past decade, there have been many regional, national and European projects focused on the development of platforms for secure access and sharing of distributed patient information. A platform is needed because present local or enterprise-wide information systems are typically not intended for cross-organisational secure access of patient data. Most of the present secure platforms are local or regional. Commonly used platform types in the health care environment vary from secure point-to-point communication systems to internet-based portals. This paper defines an enhanced cross-security platform which makes it possible for different kinds of local, regional, and national health information systems to communicate in a secure way. The proposed evolutionary way interconnects regional or national security domains with the help of a cross-platform zone. A more revolutionary model based on peer-to-peer Grid like networks and dynamic security credentials is also discussed. The proposed evolutionary model uses cross-domain security and interoperability services to ensure secure communication and interoperability between different security domains. The platform supports both communication defined beforehand and adhoc dynamic access to distributed electronic health records (EHRs). The internet is proposed as the "glue" between different regional or national security domains.

HIPAA compliance in the OR.

Many current information management practices in the OR will have to change to comply with the Health Insurance Portability and Accountability Act and meet Joint Commission on Accreditation of Healthcare Organizations standards for managing health care information. Demands for accurate, timely, confidential, and secure data make an integrated automated system for information management imperative. Delivering health care in today's OR environment results in enormous amounts of data. Caregivers must transform this data into useable information, while protecting patient privacy, confidentiality, and the security of health care information.

Teaching secure communication: a challenge for nurse educators.

The purpose of the paper was to find and discuss methods for teaching secure communication. A survey to a sample of nursing schools was executed. The teachers were asked to define 'secure communication' and to relate teaching methods used. Theories supporting the proposed methods were discussed. Conclusively it was found that a joint task force including IMIA WG4 and the IMIA and EFMI nursing groups for selecting an educational strategy in teaching 'secure communication' is highly recommended.

Protecting and securing networked medical devices.

Designing, building, and maintaining a secure environment for medical devices is a critical component in health care technology management. This article will address several avenues to harden a health care information network to provide a secure enclave for medical devices.

Optical memory card applicability for implementing a portable medical record.

The implementation of portable record based on laser card technology is discussed in terms of data structures for quick access and software tools to reinforce security and confidentiality as required by medical data. Experimental results from a field test with a laser card technology are reviewed with regard to implementation in a large-scale and public information system. An efficient data structure is described for storage purposes, and some proposals are put forward to secure stored data.

Web-enabled medical databases: a threat to security?

An increasing number of clinical databases are being adapted to allow access through Internet protocols, particularly Hypertext Transfer Protocol (HTTP). The World Wide Web (WWW) provides a user-friendly, standardized, broadly distributed database interface; at the same time, it may also present a threat to the security and confidentiality of patient data. However, there is little empirical evidence concerning such threats. Using publicly available records we estimate the additional risk of security violations due to web-enabling a database. The evidence, though limited, suggests that the additional risk may be small relative to more traditional security threats.

The need for security--a clinical view.

Systems which process patient health data of any kind are considered to be medical information systems. Some data can be categorized as non-personal, non-identifiable, or non-patient-based such as knowledge bases. Others are considered as highly sensitive because of the 'need to know' to deliver health care to patient. Access is not only justifiable for doctors and nurses, but, for specific purposes to administrative personnel and public health organisations. Of special concern are registers on sexually transmitted diseases, mental health and genetic diseases. In future, patients might gain more autonomy and also have access to some parts of their own record. Telematics allows them to update a data base and to consult a knowledge base. Clearly, physicians in charge of the cases have a responsibility that has been recognised by law in all Western countries. Access to patient's data should take into account this responsibility. Although most health professionals would still believe that confidentiality is the main issue, it appears that data integrity and availability are as important in the context of the 'paperless' electronic record. Information should be complete and correct, to be only accessed by authorized persons. The health care environment is characterised by an open nature of clinics that leaves them vulnerable to theft, damage and unauthorized access. Disclosure of information may affect the patient's social standing as well as their general health. The health professions lack sufficiently well-defined organisational structure, culture and perceptions to support security.

Medical database security policies.

Database security plays an important role in the overall security of medical information systems. Security does not only involve fundamental ethical principles such as privacy and confidentiality, but is also an essential prerequisite for effective medical care. The general framework and the requirements for medical database security are presented. The three prominent proposals for medical database security are discussed in some detail, together with specific proposals for medical database security. A number of parameters for a secure medical database development are presented and discussed, and guidelines are given for the development of secure medical database systems.
