      abstract     = {Hospitalization is a key driver of health care costs. Thus
                      far, there are only a few longitudinal studies investigating
                      whether changes in explanatory variables lead to
                      hospitalization. Moreover, these longitudinal studies did
                      not focus on individuals in highest age.The purpose of the
                      current study was to examine the correlates of
                      hospitalization among the oldest old in Germany
                      longitudinally.A multicenter prospective cohort study
                      ['Study on Needs, health service use, costs and
                      health-related quality of life in a large sample of
                      oldest-old primary care patients (85+)', AgeQualiDe].
                      Primary care patients ≥ 85 years took part
                      [n = 861 at follow-up (FU) 7, average age of
                      89.0 years; 85-100 years]. Two waves were used.
                      Hospitalization in the last 6 months was used as outcome
                      measure. Well-established scales were used to quantify the
                      independent variables such as Instrumental Activities of
                      Daily Living Scale, Global Deterioration Scale or Geriatric
                      Depression Scale.Logistic random effects regressions showed
                      that the probability of hospitalization in the preceding
                      6 months significantly increased with increases in the
                      social network, more depressive symptoms, functional
                      decline, and increase in chronic conditions, whereas it was
                      not significantly associated with age, sex, marital status,
                      education, and cognitive impairment. Social networks
                      moderate the relationship between functional decline and
                      hospitalization.The results of the present longitudinal
                      study emphasize the association of depressive symptoms,
                      functional decline, more social networks, and chronic
                      conditions with hospitalization among the oldest
                      old.Treatments with the aim to reduce or postpone these
                      factors might also help to reduce hospitalization.},
