The index for emergency treatments of patients is the percentage of a given group in the population. The rates are standardized by sex and age, i.e. it has been corrected for the distribution by age being unequal for the different regions. Hence it is possible to compare the groups. The rates are presented as index figures, where the rate for everyone in the age group is set at 100. Between 2013 and 2014 the delimitation of patientgroups has been altered which implies a minor data breach.
