Preface

We seek to understand the nature and distribution of risks to security and privacy inherent in designing and deploying health information technology (HealthIT, eHealth; we use both terms interchangeably). We posit that achieving the appropriate balance of these risks and potential costs (to doctors, patients, hospitals, and the American taxpayer) requires careful, deliberate study to understand the nature of this new problem. [This is not occurring anywhere near the extent it needs to, and the absence of health IT industry regulation in the U.S. does not help; cf. 2009 National Research Council report on health IT summarized here - ed.]

Although health care reform in the United States is a highly-charged political issue, this Web page is not meant to be a political document or support a particular political point of view or legislative agenda. Instead, this page supplies a collection of information detailing the pitfalls and challenges involved in deploying a large-scale information infrastructure around the recording, tracking, and maintenance of patient and other medical information.

We are interested in the technical security and privacy issues that emerge from what we believe is a fundamentally different data acquisition and storage problem than previous industry efforts at record keeping for other forms of data. [Clinical computing and business computing are indeed different - ed.]

Our central hypothesis is that the government and private sector are rushing [you think? - ed.] into the deployment of eHealth technology without careful consideration of the design criteria necessary to ensure accurate and private data collection and without a realistic understanding of the costs of such a large software deployment. We certainly agree that improving the efficiency and efficacy of health care delivery while reducing the cost to the taxpayer and patients is an important and critical activity. Achieving this goal, however, demands a more careful approach than has heretofore been adopted.

Introduction

The application of information technology (especially back-office data storage applications) to various facets of medical care in the U.S.A. and other countries has often promised decreased cost, increased quality of health care, and no risk to privacy, among other benefits. Such belief in the reliability and integrity of information systems is an unwarranted leap of faith on behalf of legislators and the general public. [I have written similar words - ed.]

Designing health IT systems for medical environments requires careful, thoughtful analysis. Yet, Health IT (particularly EMR systems) are de facto seen as a solution to the problem of costs, waste, fraud, and needlessly duplicated medical tests. The White House web site comments on ARRA funding for EMR work: "The Recovery Act also invests $19 billion in computerized medical records that will help to reduce costs and improve quality while ensuring patients’ privacy."

The scientific community has largely been silent on this issue, although the political rhetoric can be quite intense. Yet, most every side of the health care debate currently raging in the US accepts without question the benefits of health IT while ignoring the potential pitfalls and downsides of such technology. [Again, this is a common theme here at Healthcare Renewal - ed.]

We use the terms "eHealth" and "Health IT" interchangeably. In large part, we consider the application of computer technology in medical devices and procedures (such as remote operating rooms, advances in digital imaging, etc.) as a related but separate area from our criticism of the management of healthcare and patient information. Those systems pose different risks to patients; we comment on them only insofar as their use is driven by analysis of data held in IT systems.

Risks to the Public Trust in Computer Professionals

Hastily undertaking the transformation of the information infrastructure behind health care systems with little forethought or oversight entails the risk of the public rejecting the expertise and credibility of the computing profession. Just because we could do something does not mean that we should. There is an imperative to study the new problems posed by large-scale EMR, particularly one of national scope or connectivity. [One reason is that the risks and benefits are unknown - ed.]

No imperative exists, however, to aggressively adopt the current generation of solutions that are little more than back-office data management applications dressed up with new terminology. [This description of health IT and the lack of imperative is excellent. Adopting national HIT prior to reasonable understanding of the possible problems and risks to patients is what I have referred to as "putting the cart before the horse"- ed.]

Furthermore, academics and scientific professionals have a conflict of interest in this area. Indeed, academics stand to benefit tremendously from money being spent on this area: schools (GMU included) are quick to set up research centers dealing with various aspects of medical IT and eHealth. While there is a need for careful research into the many security, privacy, and functionality aspects of large medical IT systems, academics can be in the uncomfortable position of being funded by government or corporate money and trying to formulate an unbiased opinion as to the quality and efficacy of the state of the art in eHealth systems and practices.

Risks to Good Medicine

Health IT systems are not a panacea. Data models, systems, and user interfaces designed by computer scientists and professional software developers without much substantive input from health care professionals can lead to inefficiency and bad medicine [the common scenario for HIT development today - ed.], and risks loss of life or permanent injury to patients.

Data Leakage Models and Data Corruption Issues

One risk of large-scale EMR is a misunderstanding of the data loss dynamics of large public data systems. In addition, large databases tend to have errors: errors that are insidious and easily replicated due to the amount of automation present in such systems. It is an open question whether these errors pose a lesser or greater risk than errors due to bad handwriting on transcribed paper records. [The last point is controversial, but likely accurate - ed.]

Assessing the Cost of Large Software Projects and eHealth

Managing the design, construction, and delivery of a large software project is a complicated, fluid process. Government and industry can often fail in expensive and spectacular ways. [Indeed - ed.] Government agencies (particularly state and local government without in-house expertise), may play the role of uninformed client being sold digital snake oil at the expense of the taxpayer. Examples include the FBI's Virtual Case File system, AT&T's wireless database failure, and the Ontario eHealth scandal, among others listed below.
