To search, evaluate and integrate the best evidence of adult aerosol inhalation nursing practice, and to provide basis for the establishment of adult aerosol inhalation nursing practice standard.

The evidence-based nursing method was applied to retrieve relevant literatures from domestic and foreign databases and related websites according to the "6S" model, and the retrieval time was from the establishment of the database to October 10, 2020. The Johns Hopkins evidence grading system was used to grade the evidence. Appraisal of Guidelines for Research and Evaluation Instrument Ⅱ (AGREEⅡ) (2017 edition) and literature quality evaluation standards and evidence recommendation system (2014 edition) of Australian JBI Evidence-based Health Care Center were used to evaluate the quality of various studies and the level of evidence recommendation.

A total of 16 literatures were included, including 4 guidelines, 1 systematic evaluation, 7 expert consensus, 1 recommended practice and 3 evidence summaries. The best evidence included 6 aspects, including general principles, choice of tools, implementation process management, adverse events management, aerosol inhalation management for special patients and infection control, with a total of 32 pieces of evidence.

This study summarizes the current best evidence on adult aerosol inhalation nursing practice, which can provide evidence-based basis for standardizing the practice of aerosol inhalation by nursing staff, guarantee the standard of patient treatment and improve the quality of care.
