Purpose: To determine the pros and cons of an artificial intelligence (AI) model developed to diagnose acute rib fractures in chest CT images of patients with chest trauma. Materials and Methods: A total of 1209 chest CT images (acute rib fracture [n = 1159], normal [n = 50]) were selected among patients with chest trauma. Among 1159 acute rib fracture CT images, 9 were randomly selected for AI model training. 150 acute rib fracture CT images and 50 normal ones were tested, and the remaining 1000 acute rib fracture CT images was internally verified. We investigated the diagnostic accuracy and errors of AI model for the presence and location of acute rib fractures. Results: Sensitivity, specificity, positive and negative predictive values, and accuracy for diagnosing acute rib fractures in chest CT images were 93.3%, 94%, 97.9%, 82.5%, and 95.6% respectively. However, the accuracy of the location of acute rib fractures was low at 76% (760/1000). The cause of error in the diagnosis of acute rib fracture seemed to be a result of considering the scapula or clavicle that were in the same position (66%) or some ribs that were not recognized (34%). Conclusion The AI model for diagnosing acute rib fractures showed high accuracy in detecting the presence of acute rib fractures, but diagnosis of the exact location of rib fractures was limited.

The assessment of the Party branch is conducive to improving the quality of Party building, giving full play of the role of Party branch, and better realizing the two-way integration of Party building and health care, to promote the high-quality development of public hospitals. Oriented by problems, West China Hospital, Sichuan University comprehensively adopted a series of methods, such as literature research, Delphi method and in-depth interview and so on, to construct the index system of the Party branch assessment and explored an effective operation mechanism. As a result, the basic management was consolidated, the normalization and standardization of Party branch work was advanced, and the roles of Party branch became more prominent, which is expected to provide decision-making and work references for health authorities and national counterparts.
