      abstract     = {Demographic changes result in a higher prevalence of
                      patients suffering from dementia in hospital. In Germany,
                      epidemiological data of this target group are scarce and
                      prevalence rates from university hospitals (UH) are not
                      available. The prevalence rates and distribution were
                      analyzed on the basis of ICD-10-GM (German modification)
                      routine data METHOD: A secondary analysis on ICD-10-GM main
                      and secondary diagnoses of dementia from 2014 and 2015 from
                      5 UH was performed. All patients admitted to hospital for at
                      least 24 h and ≥18 years old (2014 n = 187,168;
                      2015 n = 189,040) were included. A descriptive analysis
                      for the >69-year-old group was carried out (2014,
                      n = 67,111; 2015; n = 67,824).The 1‑year
                      prevalence (2014/2015) for all 5 UH for patients
                      ≥18 years old was $1.3\%/1.4\%$ and for the >69-year-old
                      group, $3.3\%/3.5\%.$ The prevalence rates between the five
                      UH varied: for patients ≥18 years the range was
                      $0.44-2.16\%$ (2014) and $0.44-2.77\%$ (2015) and for
                      >69-year-olds $1.16-5.52\%$ (2014) and $1.16-7.06\%$ (2015).
                      Most cases were correlated with major diagnostic categories
                      of traumatology, cardiology, gastroenterology and
                      neurology.Analysis of ICD-10-GM routine data can provide an
                      indication of the prevalence of dementia in UH. Results of
                      the >69-year-olds varied greatly between participating UH.
                      The reasons for this might be different healthcare tasks,
                      especially with respect to geriatric patients; however, it
                      is also possible that assessment procedures are not
                      standardized and unreliable and therefore the coding is
                      invalid. A standardized procedure for the identification of
                      people suffering from dementia is necessary.},
