Purpose: The purpose of this qualitative study was to explore the experiences of visiting nurses and social workers providing health and social care services to the elderly living alone. We have developed and applied a community care model, SIHA (Smart In-Home Aftercare) service model, designed to improve networking and collaboration between health and social care professionals through data sharing (e.g., data derived from ICT-based smart care devices installed in care recipients’ homes). Methods: Data were collected through focus group and individual interviews with four visiting nurses and five social workers. Results: Three main themes emerged: ‘perception about the SIHA service model’, ‘experience of using the SIHA service model’ and ‘tasks to improve networking and collaboration between health and social care professionals’. Also, Nine sub-themes emerged, including ‘prejudice on the use of ICT-based care devices and ICT data’, ‘expectations for using ICT data’, ‘expectations for using the SIHA service model’, ‘benefits of using the SIHA model’, ‘difficulties of using the model’, ‘suggestions for SIHA’, ‘information sharing problems’, ‘responsibility’ and ‘prejudice and lack of understanding about other professionals’ roles and perspectives’. Conclusion: Based on the study results on the use of ICT data and data sharing between health and social care professionals, political and practical implications are suggested.
