Abstract: Objective　To develop a personalized and systematic integrated medical and nursing care model for Chinese people bereaved of their only child based on social support and polycentric governance theories.Methods　We conducted in-depth interviews with a purposive sample of key informants（10 people bereaved of their only child，8 workers from relevant health administrative departments and social organizations） from a city under provincial jurisdiction in eastern China for July to August 2017 for collecting the data about physical health，mental status，healthcare needs，support status and desired elderly care support of the bereaved people.Based on the interview results organized and analyzed with MAXQDA 12 as well as the theories of social support and polycentric governance，we developed an integrated medical and nursing care model for the bereaved people.Results　The bereaved people rarely actively sought help，but they could receive some policy-based support from the relevant departments of the district government and community departments.Their mental status were poor，but it could be improved significantly by consoling from the fixed and familiar people（such as the workers from relevant community departments）.Their physical health needed increasing care with aging.Health status，self-care ability and preferences（including preferred elderly care） differed significantly.Those with severe disease burdens or needing to raise the third generation of family members were found with great economic pressures.In our integrated medical and nursing care model，the involved subjects delivering support for bereaved people include relevant governmental departments，relevant community departments，non-governmental institutions，relatives，friends，neighbors and so on；the support includes healthcare，health cultivation，elderly care，financial backing，psychological consolation，social participation and so forth.Conclusion　In order to satisfy the individualized elderly care needs and to offer long-term integrated medical and nursing care in an all-round way for the bereaved people，it is suggested to establish a government-leading multidisciplinary social support system，achieving the development from healthy aging to active aging，and from survival support to developmental support.
