Understanding the triggers for MET calls may help design interventions to prevent deterioration. We aimed to identify triggers for MET activation in non-cardiac surgical patients. A retrospective cohort study of adult patients who experienced a postoperative MET call at a single tertiary hospital was undertaken. The trigger and timing of each MET call and patient characteristics were collected.<\/jats:p>\n                  <jats:p>Four hundred and one MET calls occurred after 23,258 surgical procedures, a rate of 1.7% of all non-cardiac surgical procedures, accounting for 11.7% of all MET calls over the study period. Hypotension (41.4%) was the most common trigger, followed by tachycardia (18.5%), altered conscious state (11.0%), hypoxia (10.0%), tachypnoea (5.7%), \u2018other\u2019 (5.7%), clinical concern (4.0%), increased work of breathing (1.5%) and bradypnoea (0.7%). Cardiac and\/or respiratory arrest triggered 1.2% of MET activations. Eighty-six percent of patients had a single MET call, 10.2% had two, 1.8% had three and one patient (0.3%) had four. The median interval between post-anaesthetic care unit (PACU) discharge and MET call was 14.7\u2009h (95% confidence interval 4.2 to 28.9\u2009h). MET calls resulted in intensive care unit (ICU) admission in 40 patients (10%), while 82% remained on the ward, 4% had a MET call shortly after ICU discharge and returned there, 2% returned to theatre, and 2% went to a high dependency unit.<\/jats:p>\n                  <jats:p>Hypotension was the most common trigger for MET calls after non-cardiac surgery. Deterioration frequently occurred within 24\u2009h of PACU discharge. Future research should focus on prevention of hypotension and tachycardia after surgery.<\/jats:p>","DOI":"10.1177\/0310057x221141107","type":"journal-article","created":{"date-parts":[[2023,6,14]],"date-time":"2023-06-14T07:09:30Z","timestamp":1686726570000},"page":"281-287","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":11,"title":["Triggers
