The electronic medical record: Diving into a shallow pool?
The rush to adopt the electronic medical record (EMR) has accelerated since the signing of the Health Information Technology for Economic and Clinical Health (HITECH) Act, part of the American Recovery and Reinvestment (ie, the Stimulus) Act of 2009. The HITECH Act provides incentives for physicians to adopt EMRs. However, I fear that our mad rush to complete adoption of the hodgepodge of currently available EMR systems may have unforeseen and unintended consequences. A skeptical look at several unresolved issues is warranted.
SO FAR, ELECTRONIC SYSTEMS ARE NOT INTERCONNECTABLE
More than 300 EMR systems are available, but only about two dozen account for most systems in use.1 So far, these systems are not interconnectable, ie, they are unable to share information, so patients seen by different physicians may still have a fragmented electronic record.
EMRs can also be inefficient to use. Many systems require logging on to a separate, password-protected system to view images. These problems are likely to go away over time with Internet-based solutions under development by Google and others, but the current lack of interconnectivity leaves much to be desired.
ELECTRONIC RECORDS ARE AT RISK
EMRs are at considerable security risk. About 13% of medical offices in the United States are using some form of EMR.2 A 1995 Harris poll revealed that 70% of Americans were concerned about the security of EMR systems.3 In 2007, the New York Times reported that more than 250,000 patients each year are victims of medical identity theft.4 A New Zealand survey revealed that 73.3% of patients were “highly concerned” about security and privacy.5 Even more troubling to physicians is the reported 13% incidence of patients withholding medical information because of security concerns. Furthermore, multiple breaches of electronic records have already been reported, including an extensive breach of the Veterans Administration system.6
DO ELECTRONIC RECORDS IMPROVE OR WORSEN THE QUALITY OF CAR E?
Proponents have repeatedly touted that EMRs improve the quality of medical care, and these claims have been used to accelerate the adoption of the EMR. The contention that EMRs improve the accuracy of billing, coding, and administrative functions is supported by considerable data; however, the evidence of the effect of EMRs on quality of care is mixed, with some information suggesting quality may not improve.
In an analysis of 750,000 patient records for a 2-year period as part of the National Ambulatory Care Survey, Linder et al7 found that the EMR was superior in one quality area, worse in another area, and the same as paper-based records in 14 other areas. They pointed out that previous studies showing improved outcomes were mainly from large institutions with internally developed EMR systems, and that outcomes reported from these “benchmark” institutions may not be broadly applicable.7 Linder et al concluded that use of electronic records “was generally not associated with improved quality of ambulatory care,”7 and that increased use of EMRs does not imply an automatic improvement in quality of care.7
Crosson et al8 evaluated diabetes care in a cross-sectional analysis of 50 ambulatory care practices from 2003 and 2004 and reported that “after controlling for potential practice- and patient-level confounders and for the clustering of patients within practices, patients with diabetes in practices that did not have an EMR were significantly more likely to have received care that met the guidelines for processes of care, treatment, and intermediate outcomes.”8
The Palo Alto Medical Foundation reported on the sources and types of discrepancies between EMR-listed medications and actual patient medications and found that 79.8% of the time the errors were generated by the EMR system.9 And an outpatient study that videotaped medical encounters to evaluate the accuracy of EMR in an area in which accuracy would be expected (medication lists) found that fewer than one-fifth of exchanges “ended with clear conclusions by both parties regarding prescribed medication regimens.”10 Never mind the lingering questions regarding our ability to define quality: these data provide at least some cause for concern and caution in our rush to adopt innovation in health care without proper consideration of the possible unintended consequences.
WHAT EFFECT ON MEDICAL EDUCATION?
Almost no information is available on the effects of the EMR on the process of medical student education. One could postulate and hope that embedded diagnostic algorithms and drug interaction software would facilitate the education process.
In a paper in Academic Psychiatry, Keenan et al noted that research on EMRs for education is in its infancy.11 A 2008 study of the effects of EMR on third-year medical students’ clinical experience found that students reported significant concerns about the potential impact of EMRs on their ability to conduct the doctor-patient encounter.12 Furthermore, 48% reported spending less time with patients face to face because of the EMR, and 34% reported less time talking to patients.12 In today’s world of off-site rotations and with nearly two dozen EMR systems in outpatient use alone, it is likely that a considerable amount of medical students’ time and effort is expended learning how to use different systems, which may detract from their actual medical experience.
Lastly, a survey of Canadian and US medical schools13 found that only 44% of schools had a policy regarding medical students’ documentation of progress notes in the EMR during ambulatory internal medicine clerkships. In an era when the medical student has been relegated to an observer in the education process, 14 the EMR has introduced yet another poorly understood variable in student education, which clearly begs for a thorough evaluation as the use of EMRs becomes more widespread. How can we maximize rather than dilute student education through the vehicle of electronic records?
