While there is little information regarding the extent of maltreatment in elderly populations, especially in developing countries, it is estimated that 4–6% of elderly people in high-income countries have experienced some form of maltreatment at home However, older people are often afraid to report cases of maltreatment to family, friends, or to the authorities. Data on the extent of the problem in institutions such as hospitals, nursing homes and other long-term care facilities are scarce. Elder maltreatment can lead to serious physical injuries and long-term psychological consequences. Elder maltreatment is predicted to increase as many countries are experiencing rapidly ageing populations.
