OBJECTIVETo summarize the general condition, regional distribution, prevalence and clinical characteristics of Shandong province based on hemophilia case registry information.

METHODSA retrospective study was carried out on 1979 hemophilia patients registered at Shandong Hemophilia Registration Center.

RESULTSThe 1979 cases have included 1704 hemophilia A and 275 hemophilia B patients. Hemophilia A was characterized as severe in 1021 patients (59.9%), moderate in 483 patients (28.4%), and mild in 200 patients (11.7%); while hemophilia B was characterized as severe in 125 patients (45.4%), moderate in 116 patients (42.2%), and mild in 34 patients (12.4%). The median age was 23 years (ranging from 1 month to 81 years), and most were young patients. Joint deformity occurred in 963 patients, and 948 patients had a family history of hemophilia. All counties of Shandong province had patients except for Changdao county and Fushan district of Yantai city. The prevalence of Heze city and Dongying city (3.39/100 000 and 3.05/100 000, respectively) were relatively higher.

CONCLUSIONThe above data revealed epidemiological and clinical characteristics of Shandong Province. Patient-centered registry system allowed a more detailed and accurate patient information, and promoted the comprehensive care of hemophilia, which also suggested the necessity for the establishment and improvement of the National Hemophilia Registry System.
