    Abstract:
    BACKGROUND: Percutaneous dilatation tracheostomy (PDT) is increasingly being used in the intensive care unit (ICU), and has probably increased the number of procedures performed. The primary aim of this study was to document the short- and long-term outcome of patients with a tracheostomy performed during an ICU stay. METHODS: Patients in our ICU who underwent an unplanned tracheostomy between 1997 and 2003 were included in this analysis. The type of tracheostomy (PDT or surgical tracheostomy) and time of the procedure were registered prospectively in our ICU database. Survival was followed using the People's Registry of Norway and morbidity data from the individual hospital record. These patients were also compared with a group of ICU patients ventilated for more than 24 h, but managed without a tracheostomy. We also compared patients who had early tracheostomy (less than median time to procedure) with those who had late tracheostomy. RESULTS: Of the 2844 admissions (2581 patients), unplanned tracheostomy was performed during 461 admissions (16.2%) on 454 patients (17.6%). The median time to tracheostomy was 6 days. The ICU, hospital and 1-year mortality rates were 10.8, 27.1 and 37.2%, respectively, significantly less than those of the group ventilated without tracheostomy. The median time to decannulation was 14 days. Patients who had early tracheostomy had a more favourable long-term survival than those who had late tracheostomy. No procedure-related mortality was registered. CONCLUSIONS: In our ICU, having a tracheostomy performed was associated with a favourable long-term outcome with regard to survival, and early tracheostomy improved survival in addition to consuming less ICU resources.
