Implementing Electronic Medical Records (EMRs) is a key advancement in modern healthcare. These systems aim to improve operational efficiency, patient care, and staff satisfaction. However, their implementation often faces challenges that affect workflows, especially in high-pressure environments like emergency rooms (ERs). This paper presents a comprehensive evaluation of an EMR system implemented at Niguarda Hospital’s ER, focusing on its impact on documentation efficiency, staff satisfaction, and overall operational performance. We employed a combination of time-based metrics and qualitative staff feedback to capture both the quantitative and human factors influencing the adoption of the system. Our findings indicate significant improvements in documentation times, patient flow, and staff workflow following the adoption of Dedalus’ EMR system. However, initial challenges, such as resistance to change and system integration issues, were also observed.
