BACKGROUND: Respiratory dysfunction often persists in post intensive care unit (ICU) patients and intermediate care facilities have been established to ensure the continuous of appropriate care. METHODS: The data of patients with difficult weaning from mechanical ventilation admitted to a respiratory intermediate unit (RIU) attached to a pulmonary department of a General Hospital, were retrospectively analyzed. Clinical characteristics, weaning from mechanical ventilation and tracheostomy, ICU readmission and RIU mortality were examined over a period of 18 years (1993- 2010) that was randomly divided into three six-year-periods. RESULTS: A total of 548 patients (age 56.7±17.9 years) [mean ± standard deviation (SD)], of whom 80% with tracheostomy in place and 37.6% with pressure ulcers, were examined. The ICU stay was 30.1±24.7 days (mean ± SD) and increased over time (p<0.05). Patients' baseline disorders were: chronic respiratory disease (41.3%), chronic cardiovascular diseases (10.6%), neuromuscular disease (22.8%) and miscellaneous (25.3%). The length of RIU stay (22.8±19.5 days) was constant over the examined periods but an increase in age and maintenance of tracheostomy were observed; 80% of patients were liberated from mechanical ventilation and 58.5% from tracheostomy, whereas the RIU mortality was 15%. CONCLUSION: In their vast majority patients with chronic respiratory failure, who were admitted to RIU,were weaned from mechanical ventilation, although in a substantial percentage the maintenance of tracheostomy was mandatory after discharge.
