1) The ICU at Reinier de Graaf Hospital in Delft works to ensure patient safety through protocols, guidelines, and an intensivist-led closed format. 2) To further increase safety outside the ICU, the hospital introduced a Medical Emergency Team (MET) in 2004 composed of ICU professionals who provide rapid response to patients experiencing medical emergencies. 3) Evidence on the impact of METs is inconclusive but most studies show benefits to patient outcomes and mortality reduction. The hospital believes early detection and treatment of deteriorating patients can prevent serious adverse events.
