Haemophilia registry of the Medical Committee of the Swiss Hemophilia Society. Update and annual survey 2010-2011.

The Haemophilia Registry of the Swiss Haemophilia Society was created in the year 2000. The latest records from October 31st 2011 are presented here. Included are all patients with haemophilia A or B and other inherited coagulation disorders (including VWD patients with R-Co activity below 10%) known and followed by the 11 paediatric and 12 adult haemophilia treatment or reference centers. Currently there are 950 patients registered, the majority of which (585) having haemophilia A. Disease severity is graded according to ISTH criteria and its distribution between mild, moderate and severe haemophilia is similar to data from other European and American registries. The majority (about two thirds) of Swiss patients with haemophilia A or B are treated on-demand, with only about 20% of patients being on prophylaxis. The figure is different in paediatrics and young adults (1st and 2nd decades), where 80 to 90% of patients with haemophilia A are under regular prophylaxis. Interestingly enough, use of factor concentrates, although readily available, is rather low in Switzerland, especially when taking the country's GDP into account: The total amount of factor VIII and IX was 4.94 U pro capita, comparable to other European countries with distinctly lower incomes (Poland, Slovakia, Hungary). This finding is mainly due to the afore mentioned low rate of prophylactic treatment of haemophilia in our country. Our registry remains an important instrument of quality control of haemophilia therapy in Switzerland.

Hemophilia Registry of the Medical Committee of the Swiss Hemophilia Society: Update and Annual Survey 2008.

The Swiss Haemophilia Registry of the Medical Committee of the Swiss Haemophilia Society was established in 2000. Primarily it bears epidemiological and basic clinical data (incidence, type and severity of the disease, age groups, centres, mortality). Two thirds of the questions of the WFH Global Survey can be answered, especially those concerning use of concentrates (global, per capita) and treatment modalities (on-demand versus prophylactic regimens). Moreover, the registry is an important tool for quality control of the haemophilia treatment centres. There are no informations about infectious diseases like hepatitis or HIV, due to non-anonymisation of the data. We plan to incorporate the results of the mutation analysis in the future.

Haemophilia registry of the medical committee of the Swiss Haemophilia Society. Update and annual survey 2009.

The Swiss Haemophilia Registry of the Medical Committee of the Swiss Haemophilia Society started in 1996 but was set as an internet-based, double password-protected facility in the year 2000. With the inclusion of patients' data from two new centres in 2009, we assume a coverage rate of about 90% of all patients with inherited bleeding disorders in our country. Data concerning the phenotype and genotype of the disorder, its severity, its therapy, the prevalence of inhibitors are readily available to the registered users, allowing quality control of haemophilia therapy at a national level, but also rapid care of the patient visiting the emergency room of another treatment centre. Basing on the available data, about two thirds of the WFH global survey can be answered; the mortality statistics shows that bleeding remains a cause of death in haemophiliacs, also in the 21th century. The Registry allows for comparisons with international datasets, especially with respect to treatment (prophylaxis vs. on-demand therapy), factor consumption and costs.
