Objective To quantitatively assess the risk of the "Internet+home care" service projects for the elderly and explore the risk sources of the service project, to provide a basis for the development of risk management strategies for the "Internet+home care" service projects for the elderly. Methods Based on literature analysis, semi-structured interviews, and questionnaire surveys, the risk points and risk sources of the"Internet+home care" service project was identified and analyzed. The possibility of risk occurrence and the severity of consequences were evaluated through expert consultation, and then a risk matrix of the "Internet+ home care" service projects for the elderly was constructed. The Borda ranking method was used to improve the classification and ranking of risk levels. Results The "Internet+ home care" service projects for the elderly include three risk levels, of which there were 5 extremely high-risk projects, 11 high-risk projects, and 5 medium-risk projects. Among these, extremely high-risk projects included nasal feeding, indwelling gastric tube, PICC maintenance, stoma care, and peritoneal dialysis care. The Borda ranking method concluded that nasal feeding, PICC maintenance and peritoneal dialysis care were the three highest-risk levels.The risk sources were classified into five categories, with nurse factors ranking first, followed by patient-related factors, management factors, home environment factors, and communication and coordination factors. Conclusion The "Internet+ home care" service projects for the elderly has a high degree of risk and a variety of risk sources, which suggests that a multi-dimensional risk management system should be built according to the risk levels and potential risk factors of different projects, focusing on preventing and controlling service projects and risk sources with high risk levels, and promoting the standardized development of "Internet+ home care" service for the elderly.
