Katahira N, Tsukasaki K. International Journal of Nursing Practice 2016; 22: 605-615 Nursing care in multifunctional small group homes providing day, visiting and overnight services for older people living at homeHome care programs for older people have been developed around the world. Nurses are key to these programs. The aim of this study is to explore details of the nursing activities used in group homes to provide a basis for describing effective nursing practices in such facilities. A self-administered questionnaire was sent to 240 randomly selected facilities throughout Japan in 2013. Responses indicated that the activities of nurses in managing the health of older people included determining the need for medical consultations, dealing with emergencies, and making arrangements for the use of flexible care services. Nursing activities were directly related to the percentage of older people in each facility with diagnoses such as dementia or heart disease. Nurses reported low general self-efficacy for some of the more specialized nursing activities they performed. Nursing activities are performed with the aim of supporting older people with high health care needs to continue living at home; are tailored to the characteristics of residents and contribute to the provision of timely health examinations and flexible arrangement of services. Findings indicate that it might be advantageous to increase the nursing staffing at these facilities, to provide care guidelines and training opportunities to increase nurse self-efficacy.
