      abstract     = {Hospitalizations of people with dementia (PWD) are often
                      accompanied by complications or functional loss and can lead
                      to adverse outcomes. Unsystematic findings suggest an
                      influence of comorbidities on the extent of differences in
                      the length of hospital stay (LOS). This systematic review
                      aimed to identify and evaluate all studies reporting LOS in
                      PWD as compared to PwoD in general hospitals.A systematic
                      review of observational studies using PubMed and ISI Web of
                      Knowledge. Inclusion criteria comprised original studies
                      written in English or German, assessment of diagnosis of
                      dementia, measurement of LOS, and comparison of people with
                      and without dementia.Fifty-two of 60 studies reported a
                      longer hospitalization time for PWD compared to PwoD. The
                      extent of the difference in LOS varied between and within
                      countries as well as by type of primary morbidity (eg,
                      injuries, cardiovascular diseases). The range of the LOS
                      difference for studies without restriction to a primary
                      morbidity was -2 to +22 days after matching or adjustment
                      for a variable number and selection of potentially relevant
                      covariates. For studies with injuries/fractures/medical
                      procedures and infectious/vascular disease as the primary
                      morbidity, the range was -2.9 to +12.4 and -11.2 to
                      +21.8 days, respectively.The majority of studies reported a
                      longer hospitalization of PWD compared to PwoD. Length of
                      hospital stay seems to be influenced by a variety of
                      medical, social, organizational factors, including reasons
                      for hospital admission, whose role should be explored in
                      detail in further research.},
