Interactive atlas on health inequalities in chronic diseases and mental health 
The interactive atlas on health inequalities is an online interactive query system on the spatio-temporal epidemiology, treatment and outcomes of chronic diseases and mental disorders. Based on a needs assessment among decision makers and potential users, this system was developed in order to structure and produce useful information from available medical data through a user-friendly interface. The Atlas provides important information for understanding the social and geographical health inequalities observed for myocardial infarction, osteoporotic fractures, diabetes, chronic pain, schizophrenia, and mood disorders. Query results are presented as maps, graphs or tables, via a dynamic online interface. The Atlas is a practical tool for health policy-makers who need access to comprehensive information on social and geographical health inequalities in the population.
