Health-related quality of life and posttraumatic stress disorder among survivors of an outbreak of legionnaires disease

Abstract

A follow-up study of 122 survivors of an outbreak of legionnaires disease (LD) in The Netherlands was conducted to determine persistence of symptoms, health-related quality of life (HRQL), and presence of posttraumatic stress disorder (PTSD). Seventeen months after diagnosis of LD, survivors completed a questionnaire assessing symptoms and HRQL and a questionnaire assessing PTSD. The most prevalent new symptoms were fatigue (in 75% of patients), neurologic symptoms (in 66%), and neuromuscular symptoms (in 63%). HRQL was impaired in 7 of the 8 dimensions assessed by the HRQL questionnaire, and 15% of patients experienced PTSD. Symptoms and impaired HRQL persisted for >1.5 years. As a result of the design of this study, it could not be inferred whether Legionella pneumophila infection, severe pneumonia in general, or the outbreak situation was responsible for impaired well-being. However, awareness of this problem by health care providers may improve the aftercare of patients. © 2002 Infectious Diseases Society of America.
