All remaining possible participants will receive a letter of invitation explaining the purpose of the study and the study protocol. Within seven days from the sending of the letter the subjects are contacted by telephone for verbal informed consent and booking an appointment at their home for further information, written consent and baseline assessment by a study nurse. If an old person due to cognitive decline is unable to answer the study questions or give informed consent, a proxy is contacted. Those accepting to participate will be randomized by computer-generated numbers into two study arms: intervention or control group. This information will be kept as a randomisation master list with the powered number of participants (450) by a research administrator. When written informed consent has been given and the baseline assessment done, the visiting study nurse will contact the administrator who will give the patient a randomisation number consecutively according to the master list. A letter will be sent within a week to inform the patient about to which group he or she has been allocated.
