The goal of this study is to assess the Long-term Outcomes of Critical Illness Survivors,including physical, psychological, and cognitive sequelae.

An increasing number of patients survive critical illness; however, the evidence reveals that over the same period the number of patients being sent to rehabilitation settings have tripled . For those who do survive, the latest data indicate that 50-70% of ICU "survivors" will suffer cognitive impairment and 60-80% of "survivors" will suffer functional impairment or ICU-acquired weakness (ICU-AW).Still,there is a lack valid data on the long-term impact on morbidity from prospective observational studies. Therefore, the investigators designed an observational cohort which cover a broader range of outcomes to quantify long-term physical, psychological, and cognitive impairment after intensive care unit (ICU).Intensive Care Unit patients survive from critical illness will be approached for study recruitment and participation.Survival rate,Quality of life,Cognitive impairments,Depression and anxiety,PTSD,Physical activity,Neuromuscular impairment will be assessed 3 or 6 months after ICU discharge.

Inclusion Criteria:

• Patients aged >17 years
• Patients in intensive care unit(ICU) with at least one organ or system dysfunction,such as respiratory failure, cardiogenic shock,or septic shock.
