Symptom Prevalence, Severity, and Distress Assessed by Memorial Symptom Assessment Scale (MSAS) in the General Population in Japan

ABSTRACT

<p>Understanding the symptoms of the general population has an important role in assessing and improving the quality of palliative care systems. However, there are no reliable epidemiological data on the symptoms of the general population in Japan. The aim of this study was to survey the actual status of the symptoms experienced by the general population in Japan. A large nationwide postal survey was conducted from January through February 2013 in Japan. A total of 2400 subjects were selected randomly from among members of the general population who were 20 to 79 years of age and lived in Japan. The Memorial Symptom Assessment Scale (MSAS) was used to multi-dimensionally evaluate symptoms experienced within the past week, and the Short Form 8™ (SF-8™) was used to assess the health-related quality of life (QOL). A total of 978 (41.1%) self-completed questionnaires were analyzed. The prevalences, severity rates, and distress rates of 35 physical and psychological symptoms were analyzed according to sex and age group. In addition, the relation between symptom severity and the health-related QOL score was evaluated. From the perspectives of public health and administrative policy, the results of this survey will most likely provide important basic data, with the ultimate goal of establishing a palliative care system in Japan. </p>
