Overall enhancement of the public health system ranks a key task and goal for the ongoing health reform.This paper described the public health development in Shenzhen amid the ongoing health reform.Shenzhen has achieved the following objectives as required in the reform:better public service by public health institutions,availability of major and primary public health services as required by the state and city,overall elevation of public health service capabilities,and significant drop of disease morbidity and mortality.Challenges ahead include room of improvement in public health service network,incentive mechanism of public health service providers,and that of public health service delivery capability.

While generative artificial intelligence(AI), exemplified by ChatGPT, demonstrated impressive capabilities in understanding the semantics and context of natural language, and generating coherent and meaningful responses, its performance in the medical field, which required high-level expertise and complex reasoning, remained uncertain. This article aimed to explore the potential applications and challenges of generative AI technology, with ChatGPT as a representative example, in enhancing the capabilities of primary healthcare services. Generative AI, represented by ChatGPT, had potential applications in enhancing primary healthcare services, including clinical assistance in diagnosis, electronic medical record documentation, remote management of chronic patients, and patient education. However, limitations such as the inability to guarantee accuracy, lack of doctor-patient interaction, language barriers, and concerns related to data security, patient privacy, and ethical considerations constrained its practical implementation. Therefore, the application of ChatGPT in improving the capabilities of primary healthcare services required extensive discussion and analysis throughout society. A comprehensive evaluation of potential risks and the establishment of corresponding policies and regulations were necessary to ensure the prudent and responsible introduction and application of ChatGPT, ultimately achieving the goal of empowering primary healthcare services.

Objective:To estimate the scale,expenditure and financing structure of potentially preventable hospitalization(PPH)for diabetes in Shenzhen,and provide data support for improving the utilization efficiency of medical and health resources.Methods:The System of Health Account 2011 was used to calculate the status of PPH for diabetes in Shenzhen and its cost scale and structure.Results:In 2019-2022,there will be a total of 441 426 avoidable hospital admissions for diabetes,hypertension,angina,influenza and pneumonia and dehydration and gastroenteritis,which cumulatively account for approximately 70.00%of admissions.The cost of hospitalization could be avoided by 525 028.06 million yuan,accounting for 6.18%of the total costs.The out-of-pocket costs were 1 762.724 4 million yuan,accounting for 33.57%of the total avoidable hospitalization costs.The out-of-pocket payment of angina pectoris,gangrene and rheumatic heart disease were higher and the proportion of out-of-pocket costs was larger.Conclusion:The large scale of hospital can be avoided in Shenzhen,and the waste of medical resources caused by unreasonable hospitalization is serious.The level of primary health care should be improved,the behavior of doctors should be regulated,the role of intervention in diseases of key populations should be increased,and the system of reimbursement of health insurance should be optimized.
