The Future of EHR Security: Good and Bad News

The future of Electronic Health Records (EHR) security will be impacted by the findings of several studies conducted in the past year. From what I can tell, these studies bring with them both good and bad news.

Access Logs Recommended for EHRs

Department of Health and Human Services’ Office for Civil Rights’ recent notice of proposed rulemaking on accounting of disclosures introduces a valuable privacy tool for individuals—the access report.

The HIPAA Security Rule’s information system activity review specification [164.308(a)(1)] requires organizations to “implement procedures to regularly review records of information system activity, such as audit logs, access reports, and security incident tracking reports.” The rule’s audit controls standard [164.312(b)] requires organizations to “implement hardware, software, and/or procedural mechanisms that record and examine activity in information systems that contain or use electronic protected health information.”

Adam Greene, the primary author of the proposed accounting of disclosures rule mandated under the HITECH Act, states that the proposed rule takes a two-pronged approach.

First, the proposed rule spells out revised HIPAA requirements to provide patients with an accounting of disclosures of protected health information to outside parties for certain purposes, such as law enforcement and public health.

Second, the proposal requires providing patients, upon request, with “access reports” that summarize who electronically accessed their information. Greene explains the rule attempts to address “What’s the best way to get the information that individuals are most interested in, which is, who has seen their records?” He points out that under the proposed rule, a patient could simply ask whether a specific individual has electronically accessed their records, or they could ask for a complete list of everyone who has accessed them.

Kate Borten, president of The Marblehead Group, a health information privacy and security consulting firm, agrees that the Access Report recommendation deserves industry support.

“Access logs and reports are the primary, if not only, way for organizations and individuals to identify inappropriate electronic snooping by otherwise authorized user—a serious problem wherever many users have access […]

HHS OIG finds Security Lacking in Health Information Technology Infrastructure

The Department’s Office of the National Coordinator (ONC) provides leadership for the development and nationwide implementation of an interoperable health information technology (HIT) infrastructure. ONC is charged with guiding the nationwide implementation of interoperable HIT to reduce medical errors, improve quality, produce greater value for health care expenditures, ensure that patients’ individually identifiable health information is secure and protected, and facilitate the widespread adoption of electronic health records (EHR).

On May 16, 2011, the Health and Human Services Office of the Inspector General (OIG) released the Audit of Information Technology Security Included in Health Information Technology Standards.

The Executive Summary states that the : “ONC had application information technology (IT) security controls in the interoperability specifications, but there were no HIT standards that included general information IT security controls. General IT security controls are the structure, policies, and procedures that apply to an entity’s overall computer operations, ensure the proper operation of information systems, and create a secure environment for application systems and controls.”

At the time of the initial audit, the interoperability specifications were the ONC HIT standards and included security features necessary for securely passing data between EHR systems (e.g., encrypting transmissions between EHR systems). These controls in the EHR systems were application security controls, not general IT security controls.

The OIG recommendations are as follows:

The ONC should broaden its focus from interoperability specifications to also include well-developed general IT security controls for supporting systems, networks, and infrastructures.
The ONC should use its leadership role to provide guidance to the health industry on established general IT security standards and IT industry security best practices.
The ONC should  emphasize to the medical community the importance of general IT security.
The ONC should coordinate its work with the Centers for Medicare […]

HHS Tiger Privacy and Security Tiger Team Findings Part 1

Last winter, the Health and Human Services Health Information Technology Policy Committee gave the following broad charge to the Privacy and Security Tiger Team (Tiger Team).

The charge is as follows: “The Tiger Team is charged with making short-term and long term recommendations to the Health Information Technology Policy Committee (HITPC) on privacy and security policies and practices that well help build public trust in health information technology and efficiency, particularly as related to the  American Recovery and Reinvestment Act of 2009 and the Affordable Care Act (ACA) which mandates a number of duties to the ONC relative to privacy and security.”

Since February 2011, the Tiger Team has conducted a number of public meetings on a variety of issues related to achieving public trust in health IT. The Tiger Team released  the  findings for public comment on April 11, 2011. The Tiger Team presented their finding to the HITPC on April 13, 2011. The complete briefing can be viewed on the www.healthit.hhs.gov/portal.

The following is a summary of the Tiger Team recommendations:

Organizations that are seeking to exchange information as part of the Nationwide Health Information Network (NwHIN) should be required to adopt baseline user authentication policies that require more than just user name and password for remote access. At least two factors should be required .
For more sensitive, higher risk transactions, an additional authentication of greater strength may be required. Similar to the Drug Enforcement Agency policy covering prescribing controlled substances.
The Office of the National Coordinator for Health Information Technology (ONC) should also work to develop and disseminate evidence about the effectiveness of various methods for authentication and reassess NwHIN policies accordingly.
ONC should work with the National Institute of Science and Technology (NIST) to provide guidance to […]
