Abstract: Objective: To construct nursing service frame for independent living and assisted living aged people in long-term care facilities. Methods: Delphi technique was used to construct index system of nursing service frame and minimum staffing qualification in long-term care facilities through a two-round expert consultation among 18 experts. Results: The effective response rates of two rounds' questionnaires were 75% and 100%, respectively. The experts’ authority, determination, and familiar coefficient were 0.874, 0.881, and 0.867. The compatibility of experts' opinion was statistically significant (P<0.01). After two rounds of consultation, the index system of nursing service frame in long-term care facilities was developed, including 3 types of service situation, namely independent living unit, assisted living unit and skilled nursing unit. In independent living unit,there were 2 first level items, 5 second level items and 18 third level items. In assisted living unit, there were 2 first level items,13 second level items and 45 third level items. Conclusion: The index system of nursing service frame and minimum staffing qualification in long-term care facilities are reliable and scientific, which can provide a basis for standardization of nursing service and nurse staffing allocation in long-term care facilities.
