Electronic prescribing (e-prescribing) is the use of a computerized system to enter and generate a prescription rather than writing it on paper.

Introduction

Electronic prescribing or e-prescribing improves patients safety and satisfaction by providing legible prescriptions. This results in decreased call backs to provider offices for clarification and faster prescription fulfillment. One study estimates that pharmacists make 150 million calls a year to physicians to clarify prescriptions (Kilbridge, 2001). Electronic prescribing can also help reduce medication spending by providing information on generic or other low-cost alternatives (Steinbrook, 2008).

In the United States, 3.5 billion prescriptions were filled in 2007 (Steinbrook, 2008). Medication prescriptions accounts for 13% of health care expenditures annually in the U.S. (Eslami et al., 2007). The Institute of Medicine announced in July 2006 their recommendation that all prescriptions be written electronically by 2010 (eHealth Initiative 2008). Medicare also announced that all Medicare Part D prescriptions must be transmitted electronically by January 1, 2009 (Surescripts, n.d.). The prescription is then sent to the pharmacy over a secure network (Lapane et al., 2008). Prescriptions that have been created through an EHR then printed or faxed are not considered e-prescriptions (Steinbrook, 2008). This technology has the potential to reduce preventable ADEs by alerting providers to drug interactions and drug allergies (Lapane et al., 2008).

Many medication errors are a result of illegible handwriting, unclear abbreviations and unclear or ambiguous orders (eHealth Initiative, 2008).

Electronic prescribingadoption has had a slow but steady growth. In March 2008, about 40,000 physicians in the U.S. were writing e-prescriptions and nearly 73% of retail pharmacies were receiving them (Steinbrook, 2008).

In 2007, approximately 35 million prescriptions were transmitted electronically through the Pharmacy Health Information Exchange operated by Surescripts(Surescripts 2007). The eRX Collaborative, another e-prescribing program, reported 5 million prescriptions transmitted in 2007. They also reported that approximately 104,000 e-prescriptions (2.1%) were changed or cancelled as a result of a safety alert by the system (eHealth Initiative, 2008).

The eHealth Initiative and the Center for Improving Medication Management documented the phases and functions of e-prescribing to demonstrate its benefits and key features. Some of the benefits are the ability to access medication history and receive notifications when a medication has been picked up or left unfilled. Another benefit is providers can receive drug safety alerts when prescribing medications. However, a study in 2008 concluded that providers override the drug dose alerts and drug-drug alerts most of the time. Approximately 1 in 4 providers override drug dose alerts most of the time or always and 40% override drug-drug interactions most of the time or always. When asked about drug-allergy alerts, they were least likely to override the alert stating that the alerts are helpful, useful and a good reminder. Providers noted that drug-drug alerts are beneficial but, at times, unnecessarily excessive or trivial (Lapane et al., 2008).

Benefits of electronic prescribing

Electronic prescribing has major benefits for providers and patients. Providers will benefit from decision support tools to assist them in prescribing medications and a decrease in the number of phone calls from pharmacies requesting clarification. Patients will receive lower costs, increased safety, and greater efficiency.
