Due to the rising life expectancy and improved treatment possibilities of chronic illness and acute care, the group of older persons will continue to increase worldwide. Concurrently, the number of older people with multi-morbidities in acute care will also increase. Geriatric rehabilitation is important for this specific population, because it has a positive effect on the improvement of functioning after hospitalization, and leads to less re-admissions to nursing homes/hospitals and to lower mortality rates.Geriatric rehabilitation is a multidisciplinary set of evaluative, diagnostic and therapeutic interventions with the purpose to restore functioning or enhance residual functional capacity in older people with disabling impairments. Geriatric rehabilitation treatment has a multidisciplinary patient-centered approach.Internationally, post-acute care rehabilitation is provided in different settings. In the Netherlands, geriatric rehabilitation is provided in the post-acute care setting of skilled nursing facilities (SNFs). However, because geriatric rehabilitation is a relatively young field of research we are still in the early stages of exploring which aspects of structure and processes may help to improve successful geriatric rehabilitation outcomes.The general aim of this thesis is to investigate various aspects of the structure and processes in geriatric rehabilitation in relation to the outcome of successful rehabilitation.LUMC / Geneeskunde Repositoriu
