abstract="OBJECTIVE: To describe the characteristics of patients presenting to an Emergency Department (ED) following overdoses; to identify risk factors for intensive care unit (ICU) admission among these patients; and to identify the rate of mortality and repeat overdose presentations over four years. <br><br>METHODS: Adult patients presenting to ED following drug overdose during 2014 were included. Data were collected from medical notes and hospital databases. <br><br>RESULTS: During the study period, 654 patients presented to ED 800 times following overdose. Seventy-eight (9.8%) resulted in ICU admission, and 59 (7.4%) required intubation; 57.2% had no history of overdose presentations, and 72.9% involved patients with known psychiatric illness. Overdose of atypical antipsychotics (AAP), age and history of prior overdose independently predicted ICU admission. A third of patients (<i>n</i> = 196, 30%) had subsequent presentations to ED following overdose, in the four years from their index presentation, with an all-cause four-year mortality of 3.4% (<i>n</i> = 22). <br><br>CONCLUSION: A history of overdose, use of AAP and older age were risk factors for ICU admission following ED presentations. Over a third of patients had repeat overdose presentation in the four-year follow-up with a mortality of 3.4%.<p /> <p>Language: en</p>",
