The Arkansas Department of Human Services has been working with Electronic Data Systems Corp. for the past 18 months to develop a computer network that will make e-prescribing available to doctors statewide before the end of the year. If all goes as planned, the network will become available just in time for doctors in Arkansas to reap the benefits of Medicare's new incentive-based e-prescribing program. The federal effort is designed to save time and reduce costly and dangerous medication errors caused by illegible handwriting and bad drug combinations.
