EuroREACH Appraisal Criteria

To inform you about the appropriateness and quality of data for your research or interest, data sources linked in the Health Data Navigator are described in greater detail where information exists. This assessment draws on the Global Health Data Charter, prepared by the World Economic Forum 2011. 


Contact information: who can be contacted to ask for data, ask for help...


Timeliness, transparency: e.g. most data collected are out of date to some degree by the time they are published and made available

Access to database

Ease: Can data be downloaded directly; if motions need to be filed, persons responsible contacted etc.


Conditions of access: e.g. data protection issues, fee

Language issues


# variables and # years available


Sample size


Geographical coverage (national, some regions, etc.). For surveys, population covered (representative or not)


Standardization: harmonized standards, taxonomies, terminologies that could help codify data, but also the number and range of technical systems present challenges in terms of interoperability


Possibility of linkage among national databases: Is there a common variable (e.g. Person ID) that makes data assignable to specific persons, providers etc. across databases


Entry errors: databases often contain entry errors, multiple common entries, other redundancies that have led to incorrect /incomplete data


Breaks: changing reporting standards leads to data incompatibility
Consistency of terminology: differences in how data are described when collected
