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

Implementation of the electronic health record has been associated with medication errors[7] increased hospital mortality.[8] Some of these problems may be due to computer interfaces that are not intuitive to use.[9]

Quality management

Research

The electronic health record can provide data for health research. One issue is protecting the privacy of patients.[10][11]
