Aim: To describe the number, diagnosis and prognosis of patients arriving to the trigger teams for trauma, suspected STEMI, suspected stroke, and Medical emergency patients (MEP) Method: Retrospective cohort study of all patients who between November 2012 and September 2015 had either a trauma, STEMI, stroke or MEP trigger team activation at arrival to Odense University Hospital – a level 1 trauma centre, a direct referral centre for patients with suspected STEMI to the catheterization laboratory or stroke, and with a trigger team at emergency department arrival of MEP patients from the local area. Results: There were 8,075 activations of a trigger team at hospital arrival, median 7.6 calls per day (range 1-18); 16.7% trauma, 28.3% STEMI, 19.7% stroke and 35.3% MEP calls. This corresponds to 161/100,000 person years (py) with trauma calls, 64/100,000 py STEMI calls, 72/100,000 py stroke calls and 340/100,000 py MEP calls. Patients from the different calls had a 30-day mortality of 12% (trauma), 8% (STEMI), 5% (stroke), and 25% (MEP). Whereas patients from trauma, STEMI and stroke calls were mainly discharged within a few ICD10 (International classification of diseases, version 10) main coding areas, patients from MEP calls had discharge diagnosis within many different ICD10 main coding areas. Conclusion: Trauma, STEMI and stroke trigger teams are used at a daily base, treat a prehospitally well-defined patient population and have a relatively low 7-day mortality. Patients with MEP calls are more frequent, have a diverse aetiology and a higher mortality than patients in the other trigger teams.
