Many experts believe that it has the potential to significantly reduce medication errors.
Simply put, POE allows for direct entry of one or more types of medical orders by a physician into a system that electronically transmits those orders to the appropriate department. For example, rather than hand write a patient's prescription, a physician using a POE system keys into a computer the prescription that is then sent electronically to the hospital's pharmacy to be filled. The electronic order entry concept began more than 20 years ago when very rudimentary systems were developed by safety innovators. Today, the technology has evolved, and many hospitals are looking closely at the potential of POE to improve patient safety. Others are also examining the use of POE systems.
