Incidence of documented diabetes
The rate of new cases (incidence) and the corresponding absolute number of new cases are critical for assessing disease dynamics. Incidence influences the future development of prevalence and the expected number of patients (Tönnies et al., 2019). Incidence itself is dependent on the development of major diabetes risk factors (Paprott et al., 2016).
Key messages
- In 2012, around 560,000 people covered by SHI developed diabetes for the first time.
- Incidence increases with age and peaks in the 80-plus age group.

Results
In 2012, the incidence of documented diabetes in Germany was 1.2% of all people covered by SHI (women 1.1%; men 1.3%). This is equivalent to 560,762 adults. An analysis by age groups shows that for both men and women, incidence increased with age and peaked in the 80-plus age group.
Conclusion
Overall, the number of documented new cases increases significantly with age. Generally, the assessment of incidence within the Diabetes Surveillance will help predict changes to the risk of developing the disease. Current results indicate a decrease in the incidence of documented type 2 diabetes (Goffrier et al., 2017).

Definition
The indicator Incidence of documented diabetes is defined as the number of persons with SHIwith newly documented diabetes in relation to all persons with SHI in a year without a documented diabetes diagnosis in the previous year. Newly documented diabetes is defined as the presence of at least one inpatient documented diagnosis or at least two outpatient documented diagnoses (E10-E14) in four quarters.
Reference population
Adults (18 years and older) are included in the analysis if they have statutory health insurance and have been insured for at least 360 days in the respective year, reside in Germany, have their health benefits fully reimbursed by statutory health insurance and have not been diagnosed with diabetes in the preceding year (n = 46.4 million persons).
Data source
Claims data from all approximately 70 million people with statutory health insurance collected in accordance with the Data Transparency Ordinance (DaTraV data).
Calculation
- Observed relative values: The quotient of the number of people with newly diagnosed diabetes in relation to the entire population with statutory health insurance in Germany and without diabetes in the previous year.
- Observed absolute values: Number of persons covered by statutory health insurance with newly diagnosed diabetes.
Data quality
DaTraV data are claims data on all people covered by SHI. DaTraV data include documented outpatient and inpatient diagnoses as well as information on prescribed medications. The quality of claims data from SHI depends on conduct of documentation. DaTraV data do not cover people insured by private health insurance and do not provide information on inpatient or outpatient care.
