Qualitative analysis identifies quality issues in clinical trials, proposing preventive measures that improve outcomes.

The study aims to identify and address quality control issues in clinical trials for large-area cerebral infarction.
Analyzed one phase II clinical trial as a research model.
Conducted a primary survey across one key center and 26 additional centers.
Developed six preventive measures based on identified quality issues.
Implemented these measures in a follow-up survey at two key centers.
Used chi-square analysis to evaluate the effectiveness of the measures.
No significant differences noted in quality issues between center A and other centers, except for PD-related issues.
Statistically significant reduction in AE-related issues at center A after preventive measures (p < 0.05).
Quality issues per subject decreased from 9.42 in the primary survey to 5.93 in the secondary survey.
AE-related issues per subject decreased from 4.58 to 2.20.
