This report examines the electronic medication administration record (eMAR) within the context of computer and informatics in nursing. It defines eMAR as an automated system for tracking medication from order to administration, emphasizing its role in improving patient safety and clinical outcomes. The report explores the importance of eMAR, its advantages, challenges, and potential for future improvement. It draws on expert opinions, nursing research, and comparative analyses to highlight eMAR's benefits in reducing medication errors, enhancing patient data access, and promoting safe medication practices. The report also discusses the barriers to eMAR implementation, such as a lack of computer literacy and resistance to change, while emphasizing the need for training and patient education. Literature findings are summarized, comparing paper-based and electronic systems, and highlighting the impact of eMAR on factors like medication errors, documentation, and clinical efficacy. Gaps in knowledge and existing challenges, including resistance to change and the need for comprehensive training, are also identified. The report concludes by emphasizing the potential of eMAR to significantly improve clinical outcomes and patient safety, provided that adequate measures are taken to address the identified challenges and gaps.
