Evolution of the MCS and PCS component of the SF-36 at 3, 6 and 12 months after ICU admission in patients with tracheostomy or no tracheostomy and prolonged mechanical ventilation.
The quality of life was measured by the Short Form-36 (SF-36) at 3, 6 and 12 months after ICU admission. SF-36 is a made of a mental (Mental Component Scale, MCS) and of a physical (Physical Component Scale, PCS) component. Each component ranges from 0 (poor quality of life) to 100 (upper quality of life). There is no significant difference in the MCS (Left panel, p = 0.5) and in the PCS (Right panel, p = 0.4) between the two groups. Two-way ANOVA.
