Unexpected life‐threating events and unexpected cardiac arrests among hospital‐wide deaths before and 1 year after introduction of a medical emergency team (MET) system. Unexpected life‐threatening events (pre‐MET 3.3% [11/331] versus post‐MET 1.5% [5/337], P = 0.14) and unexpected cardiac arrests (pre‐MET 9.1% [30/331] versus post‐MET 5.3% [18/337], P = 0.063) tended to decrease in the post‐MET period compared to the pre‐MET period. Total serious unexpected events were significantly decreased in the post‐MET period compared to the pre‐MET period (pre‐MET 12.4% [41/331] versus post‐MET 6.8% [23/331], P = 0.015).
