      abstract     = {Hospital care of older adults, especially of those with
                      dementia, is associated with a high risk of complications
                      and increased mortality. Adverse events are often triggered
                      by hospital-related factors, hence the time spent in
                      hospitals should be limited. There is little knowledge of
                      the specific factors influencing hospitalizations of older
                      persons.To assess the duration of length of stay (LOS) and
                      risk factors of increased LOS, and, specifically, the role
                      of delirium and neuropsychiatric symptoms (NPS) among a
                      large sample of older adults with and without dementia in
                      Germany.A claims data based dynamic retrospective cohort
                      study from 2004 to 2015 was conducted. People with dementia
                      (PWD) were identified using ICD-10 codes and the application
                      of diagnostic measures. A control group without diagnosis of
                      dementia (CG) were matched in a 3: 1 ratio. Multivariate
                      methods were used to investigate the factors associated with
                      LOS.7,139 PWD and 21,417 controls were included. PWD had
                      longer hospitalizations (first LOS: +4.3 days; second LOS:
                      +0.2 days) than the CG. Diagnosis of delirium was associated
                      with LOS, both for PWD (first LOS: +9.6 days; second LOS:
                      +5.3 days) and CG (first LOS: +13.7 days; second LOS: +7.2
                      days).Major determinants of LOS were similar in PWD and the
                      CG. The strongest association was found for the presence of
                      delirium and NPS. Future research should focus on prevention
                      and intervention strategies that may reduce the impact of
                      delirium as well as NPS on the length of stay especially for
                      PWD.},
