Background: Endotracheal intubation (EI) is a critical life-saving procedure commonly performed on emergency department (ED) patients who present with altered mental status (AMS).
Aims: We aimed to investigate the safety of observing, without EI, patients who present to the ED with decreased levels of consciousness (LOC).
Methods: We reviewed the data of all adult ED patients with a Glasgow Coma Scale (GCS) score ≤ 8, during the period between 2012 and 2018, in an academic tertiary care centre. Trauma patients were excluded. The patients were divided into two groups for comparison: those who were intubated and those who were not. Data on mortality, morbidity, and baseline clinical characteristics were collected and analysed.
Results: After screening 6334 electronic medical records of patients presenting to the ED with decreased LOC, only 257 patients met the inclusion criteria. 173 (67.3%) patients were intubated, while 84 (32.7%) were not. Among the intubated patients, 165 (95.4%) were intubated early (within two hours of presentation). Mortality, morbidity and length of stay for the intubated group were higher, although the baseline clinical characteristics were the same.
Conclusion: It might be safe to observe non-trauma emergency patients with a GCS score ≤ 8 without intubation. However, such decision should be taken carefully, as delayed intubation can be associated with higher mortality and morbidity
