People with haemophilia experience a progressive deterioration of their functional health status. Regular clinical assessment of functional health status provides insight into their process of disablement. As such, the development of a core-set of measurement tools is warranted. The aim of this study was to gather data to prepare a (preliminary) core set of clinically relevant and feasible instruments to assess the functional health status of adults with haemophilia, and to indicate their psychometric qualities. Therefore, clinimetric instruments frequently used in two haemophilia-resembling diseases (Rheumatoid Arthritis and Osteoarthritis) were reviewed from the literature. An extensive search in Medline yielded 13 relevant review articles, incorporating a total of 182 instruments, of which 40 were appropriate for haemophilia. Of these 40 instruments 3 measure body structures, 13 body functions, 19 activities (of which 5 are performance based and 14 self-report based), and 3 measure participation. This classification is based on the International Classification of Functioning, Disability and Health. Detailed information regarding the psychometrics (reliability, validity and responsiveness) of four instruments is described fully in the literature, whereas the psychometrics of the majority of the other instruments are only partly described. The results of this literature study may contribute to the formation of a (preliminary) core set of clinimetric instruments to assess the functional health status of adults with haemophilia. Decisions on the final core set should be held within the Musculoskeletal Committee of the World Federation of Haemophilia.
