Quality of life of critically ill patients in a developing country: a prospective longitudinal study.

[Purpose] To evaluate the quality of life of critical illness survivors in a developing country over the time after hospital discharge and to assess the influence of clinical variables on quality of life. [Subjects and Methods] A prospective longitudinal study was conducted in a large, tertiary, public hospital in Sao Paulo, Brazil. We included patients ≥18 years old, hospitalized in the intensive care unit with ≥24 hours of invasive mechanical ventilation. Quality of life was assessed using the Medical Outcomes Study 36-Item Short Form Health Survey, which was applied by telephone interview at the first, third and sixth months after hospital discharge. [Results] 75 patients were included in the study. Quality of life improved progressively after hospital discharge; role-physical was the most compromised domain. The physical component was influenced by the age. Quality of life was not influenced by Apache II categorization, length of invasive mechanical ventilation, intensive care unit stay or hospital stay. [Conclusion] Survivors of critical illness in a developing country present poor quality of life, which improves over time. Age influenced the physical component of quality of life.
