Sudden Decompensation of Patients Admitted to Non-ICU Settings Within 24 h of Emergency Department Admission

Abstract

Background Patients admitted to the hospital floor (non-intensive care (ICU) settings) from the emergency department (ED) are generally stable. Unfortunately, some will unexpectedly decompensate rapidly. This study explores these patients and their characteristics. Methods This retrospective, observational study examined patients admitted to non-ICU settings at a community hospital. Patients were identified by rapid response team (RRT) activation, triggered by acute decompensation. ED chief complaint, reason for activation, and vital signs were compared between patients transferred to a higher level of care versus those who were not. Results Throughout 2019, 424 episodes of acute decompensation were identified, 118 occurring within 24 h of admission. A higher rate of ICU transfers was seen in patients with initial ED chief complaints of general malaise (87.5% vs 12.5%, p  =  0.023) and dyspnea (70.6% vs 29.4%, p  =  0.050). Patients with sudden decompensation were more likely to need ICU transfer if the RRT reason was respiratory issues (47% vs 24%, p  =  0.010) or hypertension (9.1% vs 0%, p  =  0.019). Patients with syncope as a reason for decompensation were less likely to need transfer (0% vs 10.3%, p  =  0.014). Patients requiring ICU transfer were significantly older (74.4 vs 71.8 years, p  =  0.016). No differences in admission vital signs, APACHE score, or qSOFA score were found. Conclusions Patients admitted to the floor with chief complaint of general malaise or dyspnea should be considered at higher risk of having a sudden decompensation requiring transfer to a higher level of care. Therefore, greater attention should be taken with disposition of these patients at the time of admission.
