The electronic health record (EHR) is defined as a "computer-based systems for input, storage, display, retrieval, and printing of information contained in a patient's medical record."[1] In the future it is hoped that EHRs across different health care systems will be able to exchange patient information in regional health information organizations (RHIOs); however, this goal has been elusive.[2]

Uses

Clinical care

Successful implementations

The United States Department of Veterans Affairs has successfully implemented an electronic health record system, "VistA", across a very large health care system.[3][4]

Failed implementations

  • Kaiser - Hawaii[5]
  • Limpopo (Northern) Province, South Africa[6]

Adverse effects

Most all of the adverse effects are due to just the computerized provider order entry component of the electronic medical record.

Implementation of the computerized provider order entry has been associated with medication errors[7] This may be due to computer interfaces that are not intuitive to use.[8]

Computerized provider order entry has been associated with causing a number of unintended consequences with "new work/more work, workflow, system demands, communication, emotions, and dependence on the technology" being most severe.[9] In this study, shifts in power ("The presence of a system that enforces specific clinical practices through mandatory data entry fields changes the power structure of organizations. Often the power or autonomy of physicians is reduced, while the power of the nursing staff, information technology specialists, and administration is increased") were also observed.

The introduction of computerized provider order entry has been associated with increased hospital mortality in some[10], but not all studies.[11][12]

Quality management

Research

The electronic health record can provide data for health research. One issue is protecting the privacy of patients.[13][14]
