As a frequent and serious problem in elderly people, malnutrition is a complex health issue. It requires comprehensive care through interprofessional collaborative practice (IPCP) engaging five health professionals in primary care consisting of a physician, dentist, nurse, dietitian and pharmacist. In Indonesia, the usual care involves monthly health screening in community programmes named Posyandu. The current study aimed to explore perceptions of elderly people with malnutrition and their families’ experiences with interprofessional teams compared with usual care in primary care. This qualitative study used the phenomenological approach based on Creswell. Interviews were conducted with fourteen elderly people and their families in the intervention group and fourteen elderly people with their families in the control group. Data were analysed using the four steps of descriptive qualitative analysis described by Giorgi, including comparing the experiences of both groups. Elderly people with malnutrition in the intervention group had more valued experiences regarding two-way communication with the IPCP team and felt it involved more comprehensive care for malnutrition management. Participants in the control group experienced communication between the health care providers and elderly people; however, it was not clear enough. There were overlapping roles among health care providers in the usual care. However, both groups shared the experience that family members are partners in nutritional management. Elderly people and their families in the intervention group have more valuable experiences related to two-way communication and comprehensive care. Family as partners was experienced in both the intervention and control groups.
