Assessing health-related quality-of-life in individuals with haemophilia in China.

Haemophilia is a group of inherited, congenital diseases present all through the life. Those disorders are associated with a chronic burden of morbidity punctuated by episodes of acute deterioration in health-related quality-of-life (HR-QL). The significances of assessing HR-QL in individuals with haemophilia as an important component of the clinical database have gained increasing recognition in recent years. To the best of our knowledge, reports on the HR-QL of Chinese patients with haemophilia are not available. The purpose of this paper was to assess the HR-QL of patients with haemophilia in China. In order to do this, 179 patients with haemophilia (age 16-70) were mailed China quality-of-life questionnaire, which was designed specially for this study taking into account the culture characters of Chinese. Compared with the normal male general population, individuals with haemophilia experienced significantly lower levels of HR-QL and within the subgroups of patients, there was a gradation of HR-QL from mild < moderate < severe haemophilia patients. Age, clinical severity, degree of arthropathy, hepatitis status, salary and mean annual expenditure for replacement therapy were predictors of HR-QL. Clinical severity of the disease manifestation rather than the severity of the disease based on molecular classification was a factor that negatively influenced the HR-QL of patients with haemophilia. Arthropathies of patients with haemophilia in China were more severe than that in western countries because of the poorer medical care and were associated with their lower income and therapy cost. A large number of patients never had hepatitis or HIV serological examination. The exact prevalence of hepatitis and HIV was difficult to obtain and the HR-QL of hepatitis and HIV positive patients required further study.
