An Electronic Notification System for Improving Patient Flow in the Emergency Department

Healthcare providers make time-sensitive care decisions based on EHR data. As systems of record, the EHR is often not configured to optimally surface timely information. For patients awaiting admission, infection control concerns that potentially require private rooms can prolong stays in the Emergency Department. We aim to determine if an event-based notification platform connected with a commercial EHR can help prioritize timely information and improve patient flow in the emergency department. We undertook a pre-post analysis for patients being admitted from the emergency room who were tested for influenza. We used a primary outcome of mean time from negative test result to inpatient transfer. The median time decreased by 27%, from 4.1 hours to 3.0 hours. The distribution of transfer times pre and post-intervention were significantly different with a p-value of <0.001. Our findings support the use of event-based notification systems to improve patient flow in the emergency department.
