The accelerating adoption of electronic health record systems will have profound impacts on clinical care. It will also have far-reaching implications for public health research and surveillance, which in turn could lead to changes in public policy, statutes, and regulations. The public health benefits of EHR use can be significant. However, researchers and analysts who rely on EHR data must proceed with caution and understand the potential limitations of EHRs.Much has been written about the risk of EHR privacy breaches. This (...) paper focuses on a different set of concerns, those relating to data quality. Unlike clinical trial data, EHR data is not recorded primarily to meet the needs of researchers. Because of clinicians’ workloads, poor user-interface design, and other factors, EHR data is surprisingly likely to be erroneous, miscoded, fragmented, and incomplete. Although EHRs eliminate the problem of cryptic handwriting, other kinds of errors are more common with EHRs than with paper records. (shrink)

Comparative effectiveness research (CER) is one of the Patient Protection and Affordable Care Act's significant initiatives that aims to improve treatment outcomes and lower health care costs. This article takes CER a step further and suggests a novel clinical application for it. The article proposes the development of a national framework to enable physicians to rapidly perform, through a computerized service, medically sound personalized comparisons of the effectiveness of possible treatments for patients' conditions. A treatment comparison for a given patient (...) would be based on data from electronic health records of a cohort of clinically similar patients who received the treatments previously and whose outcomes were recorded. This framework has unique potential to simultaneously improve the quality of health care, reduce its cost, and alleviate public concerns about rationing and “one size fits all” medicine. (shrink)

The unsustainable growth in U.S. health care costs is in large part attributable to the rising costs of pharmaceuticals and medical devices and to unnecessary medical procedures. This fact has led health reform advocates and policymakers to place considerable hope in the idea that increased government support for research on the comparative effectiveness of medical treatments will eventually help to reduce health care expenses by informing patients, health care providers, and payers about which treatments for common conditions are effective and (...) which are not. Comparative effectiveness research has shown in some cases that expensive but commonly used treatments are significantly less effective than relatively inexpensive alternatives. Critics warn, however, that CER will homogenize patient care, limit patient choices, and lead to improper health care rationing and even to the denial of lifesaving treatments. (shrink)

Health information technology is becoming increasingly prevalent in medical offices and facilities. Like President George W. Bush before him, President Obama announced a plan to computerize all Americans’ medical records by 2014. Computerization is certain to transform American health care, but to ensure that its benefits outweigh its risks, the federal government must provide appropriate oversight.President Obama’s stimulus legislation, the American Recovery and Reinvestment Act of 2009, dedicated $27 billion to the promotion of health information technology. It provides payments of (...) up to $44,000 per clinician under the Medicare incentive program and $63,750 per clinician under the Medicaid program. (shrink)
