Abstract
Policy-based incentives for health care providers to adopt health information technology are predicated on the assumption that, among other things, electronic access to patient test results and medical records will reduce diagnostic testing and save money. To test the generalizability of findings that support this assumption, we analyzed the records of 28,741 patient visits to a nationally representative sample of 1,187 office-based physicians in 2008. Physicians’ access to computerized imaging results (sometimes, but not necessarily, through an electronic health record) was associated with a 40–70 percent greater likelihood of an imaging test being ordered. The electronic availability of lab test results was also associated with ordering of additional blood tests. The availability of an electronic health record in itself had no apparent impact on ordering; the electronic access to test results appears to have been the key. These findings raise the possibility that, as currently implemented, electronic access does not decrease test ordering in the office setting and may even increase it, possibly because of system features that are enticements to ordering. We conclude that use of these health information technologies, whatever their other benefits, remains unproven as an effective cost-control strategy with respect to reducing the ordering of unnecessary tests.

Through the Affordable Care Act and through the Health Information Technology for Economic and Clinical Health (HITECH) provisions of the the American Recovery and Reinvestment Act of 2009, Congress wished to bring under control the ever escalating costs of health care in the United States. This study of physicians’ electronic access to prior imaging and lab results adds to other data that indicates that the cost containment measures were merely a wish list that have failed to improve value in our health care purchasing.
As an another example, a recent report of the Congressional Budget Office on Medicare’s demonstration projects on disease management, care coordination, and value-based payment revealed that “the evaluations show that most programs have not reduced Medicare spending: In nearly every program involving disease management and care coordination, spending was either unchanged or increased relative to the spending that would have occurred in the absence of the program.”
Instead of simply wishing that these ideas would control costs, we should adopt policies that we already know are effective. We know that the financing model of the Affordable Care Act – building on our fragmented system of private plans and public programs – is the most expensive model of financing health care, and yet a model that falls far short on universality, comprehensiveness and equity.
In contrast, single payer and health service models are the least expensive, and are the most successful in achieving universality, comprehensiveness and equity. Establishing a health service model through government takeover of our entire health care delivery system is not a model that is likely to gain political traction in the foreseeable future. On the other hand, improving Medicare and converting it into a single payer national health program is much more consistent with American views of equity, justice, and choice.
We should certainly encourage the continued evaluation and development of potentially beneficial measures such as the use of health information technology. Improvement in quality and efficiency should always be our goals. But in the overall picture, such efforts would amount to mere tweaks compared to a comprehensive overhaul of the health care financing system. Let’s move forward with an improved Medicare for all.
