Background and Aim: Computerized physician order entry system is the process of entering orders electronically. It is a replacement for manual system and is considered as a part of a clinical information system. The appropriate design of this system leads to the enhancement of its capabilities, ensures orders accurately and comprehensively, and transfers information to different parts rapidly. Therefore, transfer time and the error related to the wrong path or misinterpretations will be omitted; in the end, efficiency will increase. This study aims to present different perspectives on design principles of computerized physician order entry system for stakeholders.
Materials and Methods: In this review article, Google, Google Scholar, Pub Med, Web of Science and Scopus databases were searched with some keywords related to design principles of computerized physician order entry system.
Results: Based on the performed studies, factors such as inappropriate design of links, display page, set of orders content, drug database, structure of order environment, rules, formats, mechanism of getting reports of errors, and finally clinical decision support system have led to the decrease of doctors’ performance, increase of new errors, and reduction of patients’ safety.
Conclusion: Inappropriate design leads to the increase of new errors after the implementation of system; therefore, proper and principled design of this system can lead to the improvement of practitioners’ function, decrease of prescription errors and drug side effects, reduction of costs, efficiency increase, workflow
