Things You Wanted to Know About the New HIT Standards But Were Too Afraid to Ask

In a previous post I discussed the interim final rule (IFR) that was recently promulgated by the Office of the National Coordinator for Health Information Technology (ONC).  The previous post discussed two of the four categories of standards in the IFR. This post will look at the final two categories. In order to appreciate the purpose of the final two standards, it is worth recapitulating the basic framework upon which the IFR is based.

The ONC’s framework for the standards is to first start with the meaningful use objectives. From the broad objectives of meaningful use, the ONC establishes certification criteria for these objectives. Based on the certification criteria, the ONC has adopted standards that would allow for an objective determination of whether the criteria has been met.

An example will help: One of the meaningful use objectives is “the capability to exchange key clinical information among providers of care and patient authorized entities electronically.”  To achieve this objective, “Certified EHRs” will have to meet the following criteria: “[The EHR system must] electronically receive a patient summary record, from other providers and organizations including, at a minimum, diagnostic test results, problem list, medication list, immunizations, and procedures and upon receipt of a patient summary record formatted in an alternative standard specified in Table 2A row 1, displaying it in human readable format.”

In order to guide EHR vendors (and purchasers) in fulfilling the above criteria–and likewise the larger meaningful use objective–the ONC has adopted a number of standards that EHRs must utilize in order to be certified. These standards fall into 4 general categories.

1. Vocabulary Standards — The standardized nomenclatures and code sets used to describe clinical problems and procedures, medications and allergies.
2. Content Exchange Standards –  The standards used to share clinical information such as clinical summaries, prescriptions, and structured electronic documents.
3. Transport Standards — The standards used to establish a common, predictable, secure communication protocol between systems.
4. Privacy and Security Standards — Standards relating to authentication, access control, transmission security which relate to and span across all of the other types of standards.

My previous post provided a general overview of the first two standards, the first of which specifies the language of “EHR speak,” while the second specifies standards giving that EHR vocabulary a predictable organization so as to ensure that different EHR systems can interpret the data.

In the previous post I used the analogy of the Bluebook style of citation to explain the content exchange standard and vocabulary standard. As you can see, the following two citations share the same basic organization (e.g. case name in italics, followed by the reporter volume number, name of the reporter, starting page of case, etc).

Wilson v. Mar. Overseas Corp., 150 F.3d 1 (1st Cir. 1998)

Orange County Agric. Soc’y, Inc. v. Comm’r, 893 F.2d 529 (2d Cir. 1990).

The content exchange standard is analogous to the order of the different elements of the citation. Regardless of the case, all Bluebook citations to federal court of appeals cases have this same basic organization. The part that changes is the vocabulary. As you can see in the cases above, two different reporters (publishers) have been used: F.3d and F.2d.  There are still only limited options for the vocabulary of court reporters.  Likewise, even though the organization of a patient’s record will remain constant, it will obviously consist of different terms depending on, among other things, the patient’s diagnosis and test results. The possible terms within the chart are determined by the vocabulary standards.

Essentially, the signifier and syntax standards are meant to save us from constructing a costly high-tech Tower of Babel. A sign (word, letter, number, symbol) displayed in a particular way must have an agreed to and discernible meaning.

With these two standards in mind, a brief overview of the latter two standards is possible.

Transport Standards

Though the data is sitting on server A in a structured format–governed by the content exchange and vocabulary standards discussed above–there is more that needs to occur for the data to be useful. For example, Computer A must “know” how to send a request for that data in a way that Computer B can understand. Likewise, Computer B must “know” how to respond to Computer A’s request, i.e., how to structure the response it will give to Computer A. This is where the third category of “transport standards” becomes important.

Luckily for us, one of the transport standards (SOAP) adopted by the ONC is the same standard used by LexisNexis. This allows us to continue our analogy.

When I log onto LexisNexis, I have the opportunity to enter a citation. The citation must be entered in the same basic order that the Bluebook citation provides. Therefore, utilizing the first case cited above, I would type in:

150 F.3d 1

The name of the parties in the case is not necessary since only one case occurs at a given page (page 1) of a reporter’s (F.3d) volume (150). If I submit that citation and Lexis recognizes it, Lexis will then display the case. The beautiful thing about Lexis (and Westlaw) is that the case data, like the citations, has a specified organization–analogous to the organization specified by content exchange standards. One discrete element common to all Lexis cases is a field listing the parties’ counsel. Let’s say that I am an iPhone application developer and I want to create a simple application that would allow a user with a Lexis account to type in a citation like the one above, and in response the program would output the opposing counsel field (as opposed to the whole case). My application would need to know how to trigger Lexis’s server to go and find that information in the database. Likewise, the Lexis database must know how to package and send that data back to the client application. Thus, the fact that Lexis organizes data like citations and counsel into organized fields with specific vocabulary is not sufficient. Rather, there must be a standard governing the requests of specific information, as well as how that information should be formatted and transmitted. This is the role of the “transport standards.”

The ONC adopted two alternative standards–the SOAP standard and the REST standard–to govern requests and responses between client and server computers. As stated above, the SOAP standard is used by Lexis (and other Internet sites) to allow other applications and services to be able to interact with it. That Lexis uses the same standard as that adopted in the HIT interim final rule helps to illustrate the broad nature of  transport standards. Unlike the content exchange and vocabulary standards that are unique to the practice of health care, the transport standards ensure that services wishing to interact with a server have an agreed upon framework by which to accomplish the interaction.  As becomes obvious from this discussion, ensuring the proper implementation of the transport standards is critical to meeting the meaningful use objective described earlier that dealt with exchanging clinical information among providers. Additionally, having a specified standard for requesting and receiving the data is crucial for personal health record (PHR) services that seek to interface with the databases of health care providers in order to retrieve and display certain information to the consumer of the PHR.

Privacy and Security Standards

The fourth group of standards deals with privacy and security, and for the most part, this part of the IFR is straightforward. The reason for the straightforwardness is that the ONC has decided to model their privacy and security criteria off of HIPAA’s Privacy and Security Rules. Therefore, there are no real surprises. With that said, the HITECH Act does direct the various HIT committees as well as the ONC to look at capabilities beyond those specified in the HIPAA Security Rule. Thus, even though the IFR does not change the privacy and security landscape in any major way, there is no promise that things won’t change in the future.

Specifically,  the ONC has adopted standards for certain aspects of HIPAA but not others. For example, standards have been adopted for the encryption of data, but not for “access control” measures that are used to prevent unauthorized access at computer terminals connected to EHR systems. The ONC’s rationale is that the methods of regulating access are evolving at a rapid pace, whereas there are industry best practices available for encrypting information. As a result, the ONC requires all certified EHR systems to be capable of encrypting their data. This is somewhat remarkable given that HIPAA and HITECH do not require all entities to use encryption. The ONC believes that this capability will spur the use of encryption by making it available to all consumers of certified EHR systems. Furthermore, the implementation of encryption by HIPAA covered entities is important because it acts as a safe harbor, relieving them of the responsibility of having to report a data breach.

As Table 2B shows, the ONC distinguishes between the general encryption of stored data on the one hand and the encryption of transmitted data on the other hand. Please click on the thumbnail below to enlarge the table.

The ONC has stated numerous times that the IFR in no way changes the responsibilities of covered entities or business associates under HIPAA (and HITECH). Rather, it solely concerns the capabilities of certified EHR systems.

Below I will explore what seems to be a gaping hole in the HITECH Act. However, as with any new legislation, it is often necessary to reexamine the laws that preceded it, which in this case is HIPAA.  This is particularly true given that the HITECH Act does not replace HIPAA. Rather, it provides–amongst other things–additional security and privacy safeguards with respect to health information. To that extent,  at least a cursory reexamination of HIPAA is required before understanding HITECH and the importance of comprehensive legislation.

HIPAA was a product of the 1990’s–an era triggering nostalgic memories of grunge music  for some, and the (in)famous Macarena dance for others. For a large part of this period, the Internet was accessed by a handful of tech savvy individuals who dialed into services like CompuServ, Prodigy, and AOL.  It was during this transition that Congress felt the need to make health insurance more portable, as well as standardize the variegated electronic systems that were conducting nonstandard healthcare-related transactions. There was a concomitant concern that health information needed better protection. Thus, in 1996 Congress adopted the Health Insurance Portability and Accountability Act (HIPAA), providing HHS with the responsibility to enforce it. However, the regulation enforcing privacy and security of health information would not be implemented until years later.

HIPAA’s Privacy Rule, which describes the appropriate use and disclosure of certain health information, came into force on April 14th, 2001, updated in 2002, with compliance required by April of 2003. The Security Rule, which establishes the policies and best practices for securing health information, came into force in 2003. Thus, the Privacy and Security Rules (referred to below as HIPAA) came to life in a period of technological transition. New technologies like residential broadband Internet access and Wi-Fi networks were becoming the norm. Electronic Health Record (EHR) systems had been developed, but had only marginal penetration within certain academic medical centers and government entities. Consequently, the threats to patient privacy from early EHRs was much smaller than it is today, since these systems were not widespread and did not often share data over disparate regions. Thus, access to the systems was not necessarily available outside of the intranets where the servers were located.

Acronyms of HIPAA & HITECH

Given the historical context of HIPAA’s passage, it is easy to appreciate HIPAA’s missteps in not specifically  focusing on EHRs or PHRs.  Rather, HIPAA regulates protected health information at a broader level, focusing primarily on the “use and disclosure” of PHI by CEs, and the best practices and policies for securing the PHI itself.   To be fair, the Security Rule does focus on PHI that is stored and transmitted electronically. However, even the most stringent best practices and policies are useless if the corresponding privacy regulations are inadequate.

But the times they are a-changin’–sort of.

Buried on page 112 of the American Recovery and Reinvestment Act (ARRA)–also known as the Stimulus Bill–is Title VIII of the bill, known as the Health Information Technology for Economic and Clinical Health Act, or more commonly, the HITECH Act. One (of the many) purposes of the HITECH Act is to fill in the gaps that have emerged since the Privacy and Security rules came into force.  But like before, we are in a transition period. Whereas HIPAA’s passage coincided with a period of generalized transition towards digital information, HITECH has coincided with its own transition: the implementation of personal health records (PHRs). Unfortunately, the current HITECH Bill and regulations have serious flaws in how they protect patient information stored in PHRs. However, before discussing the problems, it is only fair to discuss the benefits to privacy and security that HITECH’s passage has provided.

Specifically, HITECH introduces breach notification requirements. HITECH’s provisions govern the procedures which CEs and BAs must follow if health information has been compromised. HITECH also empowers the FTC to promulgate regulations pertaining to the notification procedures of PHR vendors (as well as those who offer services to PHR vendors). The FTC’s proposed breach notification requirements can be found here. Thus, CEs, BAs, and PHR vendors are, for the first time, required by law to notify individuals if their unsecured PHI has been accessed by unauthorized individuals.  Surprisingly, this was not required under HIPAA. CEs were obligated to notify individuals only insofar as the CEs were required by HIPAA to mitigate damages. But now, with the passage of HITECH, breach notification is no longer amorphous, but is spelled out in detail in HITECH’s regulations.

Additionally, HITECH requires BAs to abide by many of the same privacy and security requirements that CEs have had to abide by. Before HITECH, a BA, such as an attorney reviewing the PHI of a CE, was required to sign an agreement promising to protect the PHI that they were accessing, but were not themselves regulated by HIPAA. Thus, BAs had only contractual liability to the CE if the BA violated the rules of the agreement. On the other hand, if a CE violated HIPAA, it was subject to specific penalties and fines by the government.

Under HITECH, BAs must now comply with much of the Privacy and Security Rule, and face many of the same penalties and fines if they violate HIPAA regulations. That is, BAs are now accountable to the government if they improperly use or disclose PHI, or fail to adequately secure PHI.

HITECH also offers other benefits, such as increased enforcement of violations, a strengthening of the requirement that only the minimum necessary information is disclosed to other CEs or BAs, a more thorough framework of accounting for uses and disclosures, as well as a certain prohibitions on the sale of PHI.

The last benefit of HITECH–the prohibition on the sale of PHI–is a perfect springboard for discussing the potential pitfalls of HITECH. The benefits of HITECH may well be sufficient to shore up HIPAA’s gaps when it comes to regulating CEs and BAs. However, as HITECH’s regulatory language makes clear, there remains a gaping hole:

(d) Prohibition on Sale of Electronic Health Records or Protected Health Information-

(1) IN GENERAL- Except as provided in paragraph (2), a covered entity or business associate shall not directly or indirectly receive remuneration in exchange for any protected health information of an individual unless the covered entity obtained from the individual, in accordance with section 164.508 of title 45, Code of Federal Regulations, a valid authorization

The emphasis is added to underscore that PHRs are not included in this provision. There is no corresponding provisions in the FTC’s proposed regulations which concern breach notification. The upshot of this is that, as of the date of this posting, PHR services like Google Health and Microsoft HealthVault are not subject to this prohibition, nor is there a provision in HITECH mandating that PHRs comply with HIPAA’s Privacy and Security Rule. Therefore, PHR vendors can use, disclose–and possibly even sell–an individual’s health information outside of the HIPAA and HITECH regulations. This problem underscores a larger issue: PHRs are not regulated by HIPAA, and only regulated by HITECH insofar as the FTC’s interim rule requires certain breach notification procedures. Read more
