ME/CFS is characterized by debilitating fatigue in addition to other physical and cognitive symptoms. It is estimated to affect over 800,000 adults in the U.S. ME/CFS often results in diminished functionality and increased economic impact. The economic impact of an illness is generally divided into two categories: direct and indirect costs. Despite high prevalence rates and the disabling nature of the illness, few studies have examined the costs of ME/CFS at the individual and societal level. In fact, of the four studies examining the economic impact of ME/ME/CFS only two used a U. S. sample. The current study used community and tertiary samples to examine the direct costs of ME/CFS.
Using archival data, Study 1 examined the direct cost of ME/CFS in a community-based sample in Chicago. Study 2 estimated the direct cost of ME/CFS in a tertiary sample in Chicago. Both Study 1 and Study 2 assessed direct costs using office visit costs, medical test costs, and medication costs.
For Study 1, the annual direct total cost per ME/CFS patient was estimated to be $2,342, with the total annual direct cost of ME/CFS to society being approximately $2 billion. In Study 2, the annual direct was estimated to be $8,675 per ME/CFS patient, with the total annual direct cost of ME/CFS to society being approximately $7 billion.
Using ME/CFS prevalence data of 0.42 and indirect costs estimates from Reynolds et al. (2004), the direct and indirect cost of ME/CFS to society was estimated to be $18,677,912,000 for the community sample and $23,972,300,000 for the tertiary sample. These findings indicate that whether or not individuals are recruited from a community or tertiary sample, ME/CFS imposes substantial economic costs.
肌痛性脑脊髓炎/慢性疲劳综合征(ME/CFS)的特征是除了其他身体和认知症状外,还伴有使人衰弱的疲劳。据估计,美国有超过80万成年人受其影响。ME/CFS常常导致功能下降和经济影响增加。疾病的经济影响通常分为两类:直接成本和间接成本。尽管该疾病患病率高且具有致残性,但很少有研究在个体和社会层面考察ME/CFS的成本。事实上,在四项考察ME/CFS经济影响的研究中,只有两项使用了美国样本。本研究使用社区样本和三级医疗机构样本考察ME/CFS的直接成本。
研究1利用存档数据,在芝加哥一个基于社区的样本中考察ME/CFS的直接成本。研究2在芝加哥的一个三级医疗机构样本中估计ME/CFS的直接成本。研究1和研究2均使用门诊就诊费用、医学检查费用和药物费用来评估直接成本。
对于研究1,每名ME/CFS患者每年的直接总成本估计为2342美元,ME/CFS对社会的年度直接总成本约为20亿美元。在研究2中,每名ME/CFS患者的年度直接成本估计为8675美元,ME/CFS对社会的年度直接总成本约为70亿美元。
利用0.42的ME/CFS患病率数据以及雷诺兹等人(2004年)的间接成本估计,社区样本中ME/CFS对社会的直接和间接成本估计为186.77912亿美元,三级医疗机构样本为239.723亿美元。这些发现表明,无论个体是从社区样本还是三级医疗机构样本中招募,ME/CFS都会带来巨大的经济成本。
