Step-by-step explanation:
The acronym CPOE stands for computerized physician order entry. It is a system used in the medical field that allows healthcare providers, particularly physicians, to enter medical orders into a computer system that is directly linked to a hospital's pharmacy, laboratory, and radiology departments. Essentially, CPOE is used as a tool to improve the accuracy and efficiency of the ordering process, reduce errors associated with handwriting, and enhance overall patient care.
With the implementation of CPOE, healthcare practitioners can prescribe medication, order laboratory tests, and request radiology services electronically. In addition to reducing medical errors, CPOE systems can include decision support features, such as alerts for potential drug interactions or suggestions for clinical guidelines, which assist healthcare providers in making more informed decisions.
