CPRS is released as VISTA open source system which shows adult advisories for preventive services produced by the Veterans Administration computer-based patient record system. (web reference accessed sep 17, 2005 http://www.vistasoftware.org). a powerful feature of electronic medical records is their use of protocols or algorithms to review the patient's electronic data and provide alerts and remindres aobut any unmet goals of those protocols to clincial decision markers.

Clinical users may optionally complete any "due" reminders, browse applicable reminders, or review completed reminders.

Results:

The use of computers to remind physicians about associated orders as they write orders that trigger additional suggested orders can be implemented effectively without incurring significant ongoing costs, if physicians were already writing orders by using computer workstations. One estimate from another similar study suggested that computer interventions during order-entry could have the potential to reduce adverse effects by 25 – 49%, leading many hospitals to fast-track implementation. Further, presentation of fully-configured order suggestions made this approach more competitive from a time perspective when compared to the previous paper-based system. Systems can be configured to present information to physicians in a w ay that allows them to proceed without stopping to think about ordering follow-up tests, or enter instructions about an order. They have the option of quickly scanning the order, and accepting the order with a single keystroke or mouse click.
