Background: There is little data on the 3 year prognosis and quality of life of patients on long-term (>72 hour) mechanical ventilation in a medical intensive care unit (MICU).
Methods: Patients with long-term mechanical ventilation from May 2003 through July 2003 in MICU of Asan Medical Center, Seoul were enrolled in this studay. The survival rates were observed prospectively at 1, 3, 6, 12, 24, 36 months, and the quality of life of survivor was measured at 12 months by using Short Form 36 (SF-36).
Results: The survival rate at 1, 3, 6, 12, 24 and 36 months was 54.8% (40/73), 39.7% (29/73), 30.1% (22/73), 20.5% (15/73), 18.3% (13/71) and 16.9% (12/71), respectively. There was a similar survival rate regardless of the diseases that required mechanical ventilation. A neoplasm or chronic liver disease had a worse survival rate than chronic lung or kidney disease (p>0.05). Each SF-36 domain except for the Role-emotional was inferior to the general population.
Conclusions: The survival rate of patients with mechanical ventilation more than 72 hours is decreases continuously until 12 months but is relatively constant from 12 to 36 months. In these patients quality of life is also decrased.
