Clinical Trial Summary

This project will use literature analysis, expert research, real-world data mining and other methods to investigate the current status of the application of antimicrobial aerosolized inhalation in healthcare institutions, combine expert recommendations and real-world data analysis results to explore potential risk points in the process of antimicrobial aerosolized drug delivery, and sort out the key points of drug use management in healthcare institutions and the key points of regulatory recommendations for healthcare institutions.

Description:

The current status of nebulised inhalation of antimicrobial drugs was examined by the main subject through literature search and expert research. The researchers selected patients who visited or were admitted to Qianfoshan Hospital in Shandong Province during the period from 1 January 2021 to 31 December 2023, extracted data according to the inclusion and exclusion criteria, and used tobramycin inhalation solution as the study group, and injectable antimicrobials used by inhalation such as amikacin, polymyxin E sodium methanesulfonate, polymyxin E sulphate, polymyxin B sulphate and other antimicrobials in a multicentre real-world cohort study as the control group, and adopted a multi A multi-centre real-world cohort study was conducted to examine the effectiveness, safety and economy of nebulised inhalation of antimicrobial drugs in different levels of healthcare institutions in China, to directly compare the risk of use of injectable over-the-counter nebulised inhalation with that of inhalation formulations, and also to provide post-marketing re-evaluation for the newly marketed tobramycin inhalation solution and to provide evidence-based evidence for the rational use of medication in the clinic.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Total Adverse Reaction Incidence Rate	To evaluate the safety of injectable over-the-counter nebulized inhalation versus inhalation formulations by analyzing the incidence of total adverse reactions, and to provide first-line, real-world data to support post-market re-evaluation.	Through study completion,up to half a year.
Primary	Pathogen clearance	To evaluate the effectiveness of the clinical application of injectable over-the-counter nebulized inhalation versus inhalation formulations by analyzing the pathogen clearance rate, and to provide first-line real-world data support for post-market re-evaluation of the product.	Through study completion,up to half a year.
Primary	Average hospitalization cost per visit	To provide first-line, real-world data support for post-market re-evaluation of the product by analyzing the average per-hospitalization cost to evaluate the economics of the clinical application of injectable over-the-counter nebulized inhalation versus inhalation formulations.	Through study completion,up to half a year.
