Annual Global Survey Data

The WFH Annual Global Survey data includes selected demographic and treatment data on people with hemophilia, von Willebrand disease, rare factor deficiencies, and inherited platelet disorders throughout the world. The WFH thanks our national member organizations for their help in gathering this important data. The interactive graphs accessible on this page are based on WFH Annual Global Surveys from 1999 to 2017.

With the Patients per 100,000 option, 0 means < 1 patient per 100,000 people.

Disclaimer: This graph demonstrates the number of patients reported in the specific year. Not all of our members are able to report every year. A list of participating countries and the last year they provided data can be found in the Report on the Annual Global Survey of the years shown.

Where there is no color on the map, no data were reported by the country for that year.

Severity defined by factor level: severe, <= 0.01 international units (IU); moderate, 0.01 to 0.05 IU; mild, > 0.05 IU

Map of FVIII use per capita

Loading...

Note: Factor VIII per capita is used as a general indicator of levels of treatment because, in all care systems, it is proportionately the largest expenditure. The WFH has established that one international unit (IU) of FVIII clotting factor concentrate per capita should be the target minimum for countries wishing to achieve optimal survival for the hemophilia population. Higher levels would be required to preserve joint function or achieve a quality of life equivalent to an individual without hemophilia. Furthermore, some FVIII products are used in the treatment of von Willebrand disease and not exclusively for hemophilia A.

Disclaimer: Where there is no color on the map, no data were reported by the country for that year.

FVIII and FIX use per capita -

The red line indicates 1 IU per capita of factor VIII. The WFH has established that one international unit (IU) of FVIII clotting factor concentrate per capita should be the target minimum for countries wishing to achieve optimal survival for the hemophilia population. Higher levels would be required to preserve joint function or achieve a quality of life equivalent to an individual without hemophilia.

The red line does not apply to factor IX. Where there is no number for factor IX, no number was reported.

Countries that did not provide data have been excluded from this chart.

Identified patients over time (latest) -

The numbers represent total number of patients identified since 1999. That is, if a country reported one year and not after, the latest data was used under the assumption that the number of patients did not change substantially from one year to the next. This reflects an estimate of the total number of identified patients with inherited bleeding disorders.

HTC: Hemophilia Treatment Centre (HTC) - a medical centre providing any level of care (including basic diagnosis and treatment) for inherited bleeding disorders.

HCCC: Hemophilia Comprehensive Care Centres - centers which have direct access, within the same structure, to at least the following: hemophilia doctor, nurse, physiotherapist, social worker, and special coagulation laboratory

With the Patients per 100,000 option, 0 means < 1 patient per 100,000 people.

The numbers represent total number of patients identified for the selected time frame. That is, if a country reported one year and not after, the latest data was used under the assumption that the number of patients did not change substantially from one year to the next. This reflects an estimate of the total number of identified patients with inherited bleeding disorders.

Percent of identified patients - vs regional comparison

The percentage of expected vs. identified number of patients. This chart compares the selected country to the countries within the same region. The expected number of patients is calculated based on the prevalence of 21 per 100,000 males as estimated by Iorio et al. (2019).

Participation in the Annual Global Survey is voluntary. The numbers in this Country Profile are as reported by our national member organizations. They are not independently verified by the WFH. Fluctuation in numbers over time can reflect a change in the data collection system for the country. Missing or discrepant values are due to missing or incomplete submission of the questionnaire.

The AGS country profiles are developed under the supervision of the WFH Data & Demographics Committee.

The expected number of patients is calculated based on the prevalence of 21 per 100,000 males as estimated by Iorio et al. (2019)
