Abstract: Objective To establish the nursing quality evaluation index system for children with bronchial asthma by Delphi method. It can provide quantitative tools for the quality of care management and improve the quality of care for children with bronchial asthma. Methods The research group was established, and the indicators to be selected were formulated through literature review, semi-structured interviews and expert meetings. Selected 30 experts in nursing management, pediatric respiratory care and pediatric respiratory medicine from all over the country to participate in the consultation. Index elimination criteria: average score <4, or full score rate <50%, or coefficient of variation > 0.25. The expert positive coefficient was reflected by the effective recovery rate of the questionnaire, the authority coefficient was reflected by the average value of the judgment basis coefficient and the familiarity coefficient, and the coordination degree of all experts on the indicators was reflected by the Kendall W coordination coefficient. Finally, the AHP method is used to calculate the weight coefficient of each index. Results A total of 28 experts completed 2 rounds of correspondence effectively. The effective recovery rate of the first round of correspondence questionnaire was 93.3%; The coefficient of expert familiarity was 0.82, the coefficient of judging basis was 0.90, and the coefficient of authority was 0.86. Kendall W concordance coefficient was 0.34, χ²=526.94, P<0.01. The effective recovery rate of the second round of correspondence questionnaire was 100.0%; The coefficient of expert familiarity was 0.84, the coefficient of judgment basis was 0.94, and the coefficient of expert authority was 0.89. Kendall W concordance coefficient was 0.52, χ²=427.45, P<0.01. The final evaluation index system of children's bronchial asthma care quality includes 3 primary indexes, 12 secondary indexes and 43 tertiary indexes. Conclusions The quality evaluation index system of care for children with bronchial asthma established in this study provides a scientific and reliable tool for the care quality supervision of this disease, which is helpful to identify problems and rectify them, and continuously improve the quality of care.
