Terminally ill patients can benefit from hospice care, which specifically addresses the needs of patients and families affected by terminal illness. However, there is a lack of standardized evaluation criteria to assess the quality of hospice care for terminally ill patients in the ICU, and it is impossible to evaluate the service quality of hospice care. To use the Delphi method to construct a hospice care system for terminally ill patients in ICU that meets clinical needs, and to provide theoretical support for nursing decision-making of terminally ill patients in clinical ICU.Obtain relevant literatures by entering specific key words into the database, the hospice care nursing system for terminally ill patients in ICU was preliminarily drawn up by literature analysis, and 24 experts in this field were consulted for 3 rounds by Delphi method to discuss the development status of hospice care and finally establish the hospice care nursing system.In the three rounds of letter inquiries, the positive coefficients of experts were all high, the expert authority coefficient (Cr) were 0.864, 0.849, 0.832, and the expert opinion coordination coefficient(W) were 0.186, 0.319, 0.224; The system includes 8 first-level indicators, 27 second-level indicators and 9 third-level indicators.In this study, three rounds of Delphi consultation methods were used to construct an evaluation index system for the nursing quality of hospice care for ICU patients. The evaluation indicators formulated closely focus on the physiological and psychological characteristics of ICU patients, which can provide a better reference for ICU patients with advanced life in the future.© 2024 Wang et al.
