| Abstract: | AimsTo examine interventions and timing of emergency team calls in hospitals with or without a medical emergency team (MET).MethodsInterventions were recorded, categorized and classified as critical care interventions (e.g. airway intervention, ventilation and use of inotropic drugs); ward level interventions (e.g. fluids, oxygen by mask); assessment, physical examination and investigations.ResultsOnly 5 of the 2376 calls were free of critical care interventions. For non-cardiac arrest-related calls, MET hospitals had a lower proportion of airway, circulation and drug-related interventions and a higher proportion of ward level interventions. The majority of calls were between 0601 and 1200 h and cardiac arrest survival was greatest in the 1200-2400 h period. Overall median time at the scene was 25 min.ConclusionsNearly all emergency team calls required critical care type interventions. Emergency team calls show a unique temporal pattern for both MET and control hospitals. These findings have important organizational and resource-related implications for hospitals evaluating and establishing rapid response systems. |
