[Primary care in homes for the elderly].

Dutch GP's (General Practitioners) take care of people living in homes for the elderly. The population of these homes is selected on the basis of poor functioning on ADL (activities of daily living). We expected to find a group of elderly people within these homes that need more complex primary care. We describe the characteristics of care for an institutionalized elderly population and compare these to the care provided to their independently living peers. The design of this study is a matched case-control study in a Dutch General Practice in the study period 1/1/1998 to 1/7/2004. Our main results show that the rate of cognitive problems is two times, the prevalence of depression even three times higher in older people living in a home for the elderly than in those who live independently. Locomotory problems are a frequent problem in homes for the elderly. Rates of chronic pulmonary problems, atherosclerosis-related diseases and urinary tract infection are higher, whereas no significant differences for CVA, diabetes and cancer were found. Institutionalized older patients use more different types of medication. GP's do not have more contacts with people living in a home for the elderly than with older people living independently. We conclude that people living in homes for the elderly have complex problems, and need special attention for their specific vulnerability. Differences in care are not primarily explained by chronic disease but by problems with mobility, confusion, depression and cognition.
