With the aging of the population in Japan, the construction and operation of a comprehensive community care system is being promoted, the demand for home medical care is increasing, and collaboration with other occupations is becoming essential. As a way of thinking as a recuperator at home, grasp the “view and way of thinking” of the International Classification of Functioning, Disability (ICF) model and utilize the recuperator's own abilities, self-help, mutual aid, and public assistance in the community. It is necessary to keep in mind that we will cooperate with local residents and utilize related facilities, occupations, etc. to provide support. In addition, the concept of collaboration and the multidisciplinary collaboration competencies in the medical, health, and welfare field that can be utilized even when it is difficult for other occupations to collaborate in homecare are summarized. We believe that it is necessary to utilize ICT in home medical care, further accelerate cooperation with other occupations, and respond flexibly to the needs of homecare recipients befitting professional standards.
