== Patient safety benefits == In the past, physicians have traditionally hand-written or verbally communicated orders for patient care, which are then transcribed by various individuals (such as unit clerks, nurses, and ancillary staff) before being carried out. Handwritten reports or notes, manual order entry, non-standard abbreviations and poor legibility lead to errors and injuries to patients, . A follow-up IOM report in 2001 advised use of electronic medication ordering, with computer- and internet-based information systems to support clinical decisions. Prescribing errors are the largest identified source of preventable hospital medical error. A 2006 report by the Institute of Medicine estimated that a hospitalized patient is exposed to a medication error each day of his or her stay. While further studies have estimated that CPOE implementation at all nonrural hospitals in the United States could prevent over 500,000 serious medication errors each year. Studies of computerized physician order entry (CPOE) has yielded evidence that suggests the medication error rate can be reduced by 80%, and errors that have potential for serious harm or death for patients can be reduced by 55%, and other studies have also suggested benefits. Further, in 2005, CMS and CDC released a report that showed only 41 percent of prophylactic antibacterials were correctly stopped within 24 hours of completed surgery. The researchers conducted an analysis over an eight-month period, implementing a CPOE system designed to stop the administration of prophylactic antibacterials. Results showed CPOE significantly improved timely discontinuation of antibacterials from 38.8 percent of surgeries to 55.7 percent in the intervention hospital. CPOE/e-Prescribing systems can provide automatic dosing alerts (for example, letting the user know that the dose is too high and thus dangerous) and interaction checking (for example, telling the user that 2 medicines ordered taken together can cause health problems). In this way, specialists in pharmacy informatics work with the medical and nursing staffs at hospitals to improve the safety and effectiveness of medication use by utilizing CPOE systems.
== Advantages == Generally, CPOE is advantageous, as it leaves the trails of just better formatting retrospective information, similarly to traditional hospital information systems designs. The key advantage of providing information from the physician in charge of treatment for a single patient to the different roles involved in processing he treatise itself is widely innovative. This makes CPOE the primary tool for information transfer to the performing staff and lesser the tool for collecting action items for the accounting staff. However, the needs of proper accounting get served automatically upon feedback on completion of orders. CPOE is generally not suitable without reasonable training and tutoring respectively. As with other technical means, the system based communicating of information may be inaccessible or inoperable due to failures. That is not different from making use of an ordinary telephone or with conventional hospital information systems. Beyond, the information conveyed may be faulty or erratic. A concatenated validating of orders must be well organized. Errors lead to liability cases as with all professional treatment of patients. Prescriber and staff inexperience may cause slower entry of orders at first, use more staff time, and is slower than person-to-person communication in an emergency situation. Physician to nurse communication can worsen if each group works alone at their workstations. But, in general, the options to reuse order sets anew with new patients lays the basic for substantial enhancement of the processing of services to the patients in the complex distribution of work amongst the roles involved. The basic concepts are defined with the clinical pathway approach. However, success does not occur by itself. The preparatory work has to be budgeted from the very beginning and has to be maintained all the time. Patterns of proper management from other service industry and from production industry may apply. However, the medical methodologies and nursing procedures do not get affected by the management approaches.
== Risks == CPOE presents several possible dangers by introducing new types of errors. Automation causes a false sense of security, a misconception that when technology suggests a course of action, errors are avoided. These factors contributed to an increased mortality rate in the Children's Hospital of Pittsburgh's Pediatric ICU when a CPOE system was introduced. In other settings, shortcut or default selections can override non-standard medication regimens for elderly or underweight patients, resulting in toxic doses. Frequent alerts and warnings can interrupt work flow, causing these messages to be ignored or overridden due to alert fatigue. CPOE and automated drug dispensing was identified as a cause of error by 84% of over 500 health care facilities participating in a surveillance system by the United States Pharmacopoeia. Introducing CPOE to a complex medical environment requires ongoing changes in design to cope with unique patients and care settings, close supervision of overrides caused by automatic systems, and training, testing and re-training all users.
