The German Diabetes Risk Score (GDRS) currently enables prediction of the individual risk of developing type 2 diabetes (T2D) within five years. The aim of this study is to extend the prediction period of the GDRS, including its non-clinical version and its HbA1c extension, to 10 years, and to perform external validation. ⋯ The extended GDRS prediction period of 10 years, with a non-clinical version and an HbA1c extension that will soon be available in both German and English, enables the even longer-range, evidence-based identification of high-risk individuals with many different applications, including medical screening.

It has been observed that the Medical Service (Medizinischer Dienst, an auditing body of the German statutory health insurance system) is more likely to audit the bill for a hospitalization in a psychosomatic clinic if the patient carries a secondary diagnosis of obesity. ⋯ Treatments of markedly obese inpatients that incurred greater expenses presumably led to a higher hospitalization audit rate as an automatic consequence of the auditing algorithms used. An unintentional statistical discrimination arose from the unjustified linkage of the audit category "quality of coding" of the secondary diagnosis (obesity) with the audit category "possible incorrect admission" with regard to the main diagnosis. Similar effects may be occurring with economically relevant secondary diagnoses in other areas of medicine as well.
