1. Position level and responsibilities: both the chief physician and the chief physician hold senior positions in medical institutions and have certain management and decision-making authority on medical diagnosis, treatment and approval. Because their positions and responsibilities are similar, they will make a consistent decision when approving.

2. Unified standards and regulations: Medical institutions will establish a set of unified standards and regulations for examination and approval to ensure fairness, accuracy and consistency in the examination and approval process. The chief physician and the chief physician need to abide by the same standards and regulations, and carry out examination and approval according to the procedures set by medical institutions, so as to ensure that the rights and interests of patients are protected and the operation of medical institutions is carried out in accordance with regulations and requirements.
