Background: In-home aged care is a vital part of Australia’s formal aged care system, offering essential support for older adults living in their homes. From 2023 to 2024, over 1.1 million Australians received in-home aged care, and this number is expected to grow. However, significant workforce shortages are currently occurring in the sector. One potential solution to workforce shortages is integrating technology into in-home aged care. Technology can support health monitoring, care coordination, emergency detection, social connection, and physical activity. Despite progress in residential aged care, community aged care lacks sufficient evidence on technological implementation. Objective: This study aims to develop guidelines for implementing digital technology for in-home aged care, considering the needs of clients, their families, care workers, and aged care providers. Methods: Guidelines were developed by a partnership consisting of a research institute and a national provider of in-home aged care. A 2-stage, mixed methods approach was used, integrating the data from a literature review, client and staff surveys, staff interviews, a co-design workshop, and case study to inform the guidelines’ content and format. Content was refined iteratively with aged care staff, older people, and researchers, using a participatory approach. Results: Seven key domains and 19 subthemes were identified as critical to the successful implementation of digital technology for in-home aged care. These included factors related to technology design, privacy and trust, training and support, organizational culture, client care, digital literacy, and perceived benefits. Each subtheme was accompanied by enablers, barriers, and practical implementation tips. The guidelines were refined through participatory methods and validated via a real-world case study involving smart glasses, demonstrating their applicability and relevance. Conclusions: The guidelines offer a comprehensive, evidence-informed framework to support aged care providers in implementing digital technology for in-home aged care. By addressing the unique challenges of in-home settings and incorporating the perspectives of clients, staff, and organizations, the guidelines aim to enhance care quality, client outcomes, and workforce sustainability. Further testing and refinement are recommended to strengthen client perspectives and evaluate broader applicability.
