[Prevalence of dementia of insured persons with and without German citizenship : A study based on statuatory health insurance data].

BACKGROUND

Elderly people with a non-German background are a fast growing population in Germany.

OBJECTIVES

Is administrative prevalence of dementia and uptake of nursing-home care similar in the German and non-German insured?

MATERIALS AND METHODS

Based on routine data, administrative prevalence rates for dementia were calculated for 2013 from a full census of data from one large sickness fund. Patients with dementia (PWD) were identified via ICD-10 codes (F00; F01; F03; F05; G30).

RESULTS

Administrative prevalence of dementia was 2.67% in the study population; 3.06% in Germans, and 0.96% in non-Germans (p value <0.001). Age and sex adjusted prevalence was comparable in the insured with and without German citizenship, except in women aged 80-84 (17.2 vs. 15.4) and for men in the age groups 80-84 (16.5 vs. 14.2), 85-89 years (23.4 vs. 21.5), and above 90 years of age (32.3 vs. 26.3). Standardized to the population of all investigated insured, 31.4% of all Germans with dementia had no longterm care entitlement vs. 35.5% of all patients without German citizenship. Of German patients, 55.1% were institutionalized vs. 39.5% of all patients without German citizenship.

CONCLUSIONS

There was a higher prevalence of dementia in the very old insured without German citizenship compared to those with German citizenship, especially in men. Non-Germans showed lower uptake of nursing home care compared to Germans. Additionally, Germans had slightly higher nursing care entitlements. It should be investigated further how much of the difference is due to underdiagnosis, cultural differences, or lack of adequate diagnostic work-up.
