Evidence shows that home visits can reduce mortality and nursing home admissions in some groups of older people. Characteristics of effective home-visiting programmes include multidimensional assessment, many follow-up visits and targeting people at lower risk of death. Home visits for older adults aim to prevent cognitive and functional impairment, thus reducing institutionalization and mortality. Some programs focus on one risk factor, such as falls. Others include multidimensional geriatric assessment (MGA) to evaluate and to improve medical, functional, psychosocial, and environmental problems and resources. Visitors may provide information, investigate untreated problems, encourage medication compliance, and provide referrals to services.
