Methodology
Orphanet carries out a systematic survey of literature in
order to estimate the prevalence and incidence of rare
diseases. This study aims to collect new data regarding
point prevalence, birth prevalence and incidence, and to
update already published data according to new
scientific studies or other available data.
This data is presented in the following reports published
biannually:
Prevalence, incidence or number of published cases
listed by diseases (in alphabetical order);
Diseases listed by decreasing prevalence, incidence
or number of published cases;
Data collection
A number of different sources are used :
Registries (RARECARE, EUROCAT, etc) ;
National/international health institutes and agencies
(Institut National de Veille Sanitaire (French Institute
of Health Surveillance); American Center of Disease
Control and Prevention, American National Cancer
Institute, European Medicines Agency, World Health
Organization etc) ;
Medline is consulted using the following search
algorithm : «Disease names» AND Epidemiology
[MeSH:NoExp] OR Incidence [Title/abstract] OR
Prevalence[Title/abstract]
OR
Epidemiology[Title
/abstract];
Medical texts, grey literature and reports from
experts;
Orphanet collaborating experts .
Data characteristics
The data published in this document are worldwide
estimations, or European estimations if a worldwide
estimation is not available.
The published data is raw collected data or
extrapolations of raw data at worldwide or European
level when no genetic founder effect is suspected as a
cause of a disease.
If a range of national data is available, the average is
calculated to estimate the worldwide or European
prevalence or incidence.
When a range of data sources is available, the most
recent data source that meets a certain number of quality
criteria
is
favoured
(registries,
meta-analyses,
population-based studies, large cohorts studies).
For congenital diseases, the prevalence is estimated, so
that:
Prevalence = birth prevalence x (patient life
expectancy/general population life expectancy).
When only incidence data is documented, the prevalence
is estimated when possible, so that :
Prevalence = incidence x disease mean duration.
When neither prevalence nor incidence data is available,
which is the case for very rare diseases, the number of
cases or families documented in the medical literature is
provided.
Limitations of the study
The prevalence and incidence data presented in this
report are only estimations and cannot be considered to
be absolutely correct.
The average values presented in this report do not take
into account the heterogeneous nature of the
methodologies employed by the studies considered in the
literature survey.
The validity and exactitude of raw data sources is taken
for granted and have not been verified. Thus, confusion
between terms such as incidence and prevalence and/or
birth prevalence is possible due to the interchangeable
use of these terms in certain sources.
It is possible that prevalence is overestimated in some
cases as epidemiological studies are generally based on
hospital data in regions with higher prevalence.
