The benefits of hydration reminders and education on risk factors and care homes' solutions for reducing delirium is still uncertain. Physical rehabilitation for older people in long-term care Physical rehabilitation can prevent deterioration in health and activities of daily living among care home residents. The current evidence suggests benefits to physical health from participating in different types of physical rehabilitation to improve daily living, strength, flexibility, balance, mood, memory, exercise tolerance, fear of falling, injuries, and death. It may be both safe and effective in improving physical and possibly mental state, while reducing disability with few adverse events. The current body of evidence suggests that physical rehabilitation may be effective for long-term care residents in reducing disability with few adverse events. However, there is insufficient to conclude whether the beneficial effects are sustainable and cost-effective. The findings are based on moderate quality evidence. Need for long-term care Life expectancy is going up in most countries, meaning more people are living longer and entering an age when they may need care. Meanwhile, birth rates are generally falling. Globally, 70 percent of all older people now live in low or middle-income countries. Countries and health care systems need to find innovative and sustainable ways to cope with the demographic shift. As reported by John Beard, director of the World Health Organization's Department of Ageing and Life Course, "With the rapid ageing of populations, finding the right model for long-term care becomes more and more urgent." The demographic shift is also being accompanied by changing social patterns, including smaller families, different residential patterns, and increased female labour force participation. These factors often contribute to an increased need for paid care. In many countries, the largest percentages of older persons needing LTC services still rely on informal home care, or services provided by unpaid caregivers (usually nonprofessional family members, friends or other volunteers). Estimates from the OECD of these figures often are in the 80 to 90 percent range; for example, in Austria, 80 percent of all older citizens. The similar figure for dependent elders in Spain is 82.2 percent. The US Centers for Medicare and Medicaid Services estimates that about 9 million American men and women over the age of 65 needed long-term care in 2006, with the number expected to jump to 27 million by 2050. It is anticipated that most will be cared for at home; family and friends are the
