Summary

In the past, due to economic and medical resource constraints, the hemophilia comprehensive care in China was suboptimal. The BCH data of both retrospective and prospective studies reveals that for 4-6y and 6-9y patients with severe hemophilia respectively: 45% and 82% of the patients have suffered from joint bleeding, with mean AJBR of 4.18 and 4.95; and 24.2% and 33.3% of them with AJBR\>10 times, led to arthropathies and made their quality of life be heavy affected. Now, with the development of economy and medical science in China, prophylaxis regimens have been initiated in more and more children with hemophilia. Considering the difference between prophylaxis regimens, the frequency of joint bleeding was reduced significantly, the quality of life of hemophilia kids improved. An assessment scoring system for the appropriate validation of individualized prophylaxis treatment regimens are urgently needed.

Before, the most important assessed indication for hemophilia prophylaxis was the frequency of joint bleeding. But increasing evidences are showing that there is a discrepancy between real joint damage and joint bleeding frequency. The single indicator of joint bleeding frequency is not sufficient to evaluate the joint status of hemophilia children.

Under the World Health Organization's ICF guidelines, the assessment scoring system for selecting prophylaxis for children with hemophilia should include the tools currently available for assessment of structure/function of the joint, patient activities and patient participation in hemophilia healthcare. According to ICF of WHO, the most common bleeding parts are elbows, knees and ankles, therefore the assessment of children with hemophilia should include the evaluation of the structure, the function of these 6 Index joints, the capacity of activities and the capacity of participation of children. These will constitute a comprehensive hemophilia evaluation system.

In China, exploration of the optimal and individualized prophylaxis regimen is urgent, and the comprehensive evaluation system should include joint structure and function, body's activities and individual participation, thus may be more appropriate for the individualized prophylaxis for Chinese children with hemophilia.
