Impact of Early Electronic Prescribing on Pharmacists' Clarification Calls in Four Community Pharmacies Located in St John's, Newfoundland.

Advanced e-prescribing functionality will enable secure transmission of prescriptions from prescribers to a patient's pharmacy of choice through a provincial electronic Drug Information System (DIS)/Pharmacy Network, which will lessen the need for clarification calls, especially in the domains of missing information and appropriateness of the prescription. This exploratory study provides valuable insight into the benefits and gaps of early e-prescribing. Advanced e-prescribing systems will provide an opportunity for further realization of quality and safety benefits related to medication prescribing.
